There is some truth to the longstanding anecdote that your locks can lose color when youre stressed.

A team of researchers has found that in mice, stressful events trigger damage the stem cells that are responsible for producing pigment in hair. These stem cells, found near the base of each hair follicle, differentiate to form more specialized cells called melanocytes, which generate the brown, black, red and yellow hues in hair and skin. Stress makes the stem cells differentiate faster, exhausting their number and resulting in strands that are more likely to be transparent gray.

The study, published Wednesday in Nature, also found that the sympathetic nervous system, which prepares the body to respond to threats, plays an important role in the graying process.

Normally, the sympathetic nervous system is an emergency system for fight or flight, and it is supposed to be very beneficial or, at the very least, its effects are supposed to be transient and reversible, said Ya-Chieh Hsu, a stem cell biologist at Harvard University who led the study.

The sympathetic nervous system helps mobilize many biological responses, including increasing the flow of blood to muscles and sharpening mental focus. But the researchers found that in some cases the same system of nerves permanently depleted the stem cell population in hair follicles.

The findings provide the first scientific link between stress and hair graying, Dr. Hsu said.

Stress affects the whole body, so the researchers had to do some sleuthing to figure out which physiological system was conveying its effects to hair follicles.

At first, the team hypothesized that stress might cause an immune attack on melanocyte stem cells. They exposed mice to acute stress by injecting the animals with an analogue of capsaicin, the chemical in chili peppers that causes irritation. But even mice that lacked immune cells ended up with gray hair.

Next, the scientists looked at the effects of the stress hormone cortisol. Mice that had their adrenal glands removed so they couldnt produce cortisol still had hair that turned gray under stress.

The system responsible for the appearance of silvery strands turns out to be the sympathetic nerves that branch out into each hair follicle in the skin.

The researchers found that the sympathetic nerve cells released a neurotransmitter called noradrenaline that was taken up by nearby melanocyte stem cells. Then a series of events unfolded in quick succession: The melanocyte stem cells proliferated and turned into specialized pigment-producing cells, which abandoned their niche near the base of the follicle and left the hair without a source of pigmentation.

In Dr. Hsus study, acute stress depleted the entire melanocyte stem cell population in mice in just five days. The researchers also found that, in petri dishes, noradrenaline prompted human melanocyte stem cells to proliferate, suggesting that the same acceleration of hair graying occurs in people, too.

I was amazed by how dramatic this change is, said Mayumi Ito, a biologist at the New York University School of Medicine who was not involved in the study. In her own research on aging mice, the graying process was gradual: The depletion of melanocyte stem cells led first to a few salt and pepper strands and then to gray or white fur, much as humans begin to see more white hair as they get older.

Dr. Itos team also found that the graying process in mice could be halted with drugs known as CDK inhibitors, which stop the proliferation of stem cells, or by blocking the release of noradrenaline.

The findings underscore the consequences of triggering a survival mechanism when the situation isnt life-threatening.

Stress is a normal part of life, but there are situations where stress is helpful and situations where it is detrimental, said Subroto Chatterjee, a biologist at Johns Hopkins University who studies the effects of stress on the cells in blood vessels.

Other studies have shown that stress is just one factor affecting how quickly hair goes gray, Dr. Chatterjee said. Genes and diet play a big role as well.

In a 2018 study, Dr. Chatterjee and his colleagues found that mice placed on the equivalent of a Western diet high in fat and cholesterol not only developed inflamed arteries, they also started going gray and experiencing hair loss. (The team also found a way to halt the process.)

But the new study is an important step toward understanding the role of stress on various tissues.

If we can know more about how our tissues and stem cells change under stress, we can eventually create treatments that can halt or reverse its detrimental impact, Dr. Hsu said.

Luke Jefferson Day, Editor of GQ Style and Fashion Director of GQ

"Sensai's SPF 6 Bronzing Gel is my winter grooming tip. I got it from my mega make-up artist friend Gina Kane, who works with Robbie Williams. It has such a light finish but gives you a little glow during the cold months."

"My winter grooming essential has been the same for the past decade or so. Bioeffect's EGF Serum is the best cold weather skin saver bar none. It contains "epidermal growth factor", sourced from apple stem cells, an ingredient that encourages skins cells to duplicate, instantly reducing dryness and producing that dewy glow we all crave (but can never quite achieve) in the winter months. Following a slick of the serum, a spot or two of Weleda's Skin Food is ultra rich and excellently moisturising."

"My go-to product during the winter months is the exfoliating energy scrub by Tom Ford. As energy is what most of us are lacking during a long dark winter, this product helps to bring you back to life and back to the reality that summer is coming (eventually)."

"In winter I use Eve Lom Intense Hydration Serum daily to maintain skin dexterity and to avoid drying, which my skin is susceptible to, especially with the mix of harsh cold outside and synthetic heat inside. I then use Eve Lom Rescue Mask once a week to try to prevent breakouts, as it utilises ground almond to gently exfoliate, camphor to reduce redness and its clay-like formulation is an excellent de-puffer. Winter sorted."

"One product I cant do without in the winter months is hair cream. My favourite is Bumble And Bumbles BB Grooming Creme. My hairs naturally pretty curly and I look absolutely bonkers when I blow dry it or make any attempt at styling. This, I just in pop once Im out of the shower with a bit of curl cream too if Im feeling dead posh and I can spend a whole day not worrying that I might look like something a bird might nest in whenever I meet a light breeze."

"During the cooler months my skin doesnt necessarily go hard and flaky, but it does get affected by the drop in temperature and definitely feels a little more dry. After having tried quite a lot of creams, I actually bought this absolute miracle worker from Awake Organics, which got rid of not only my bags (anti-ageing vitamin C to thank here), but also provided more than enough hydration to my skin. Ive used it since November (every night) and theres no looking back. Oh and its 100 per cent natural and totally affordable, which is the direction Im moving in when it comes to stocking my bathroom cabinet."

"When it comes to winter grooming I try and keep my routine as organic and natural as possible. One of my main go-to's is Dr Jackson's Everyday Oil. I add a couple of drops three or four times a week to my facial moisturiser when my skin is feeling extra dry. It's lightweight, so it doesn't have that greasy, clogging feeling to it and is infused with baobab oil that promotes elasticity in the skin."

Facelifts once had just a single focus: lifting and tightening the skin to reduce wrinkles. This resulted in a tighter but not necessarily more youthful appearance. Today, however, theres a more natural new solution: the lift-and-fill facelift. Using this technique, Dr. John Burns can lift the skin and deeper layer with less bruising, swelling, and scarring while filling areas that need volume replacement. If youre looking to refresh your appearance, you can find everything you need to know about this procedure and whether its right for you here.

What Is a Lift-and-Fill Facelift?

The lift-and-fill procedure has become increasingly popular in recent years. This procedure involves combining a facelift with the addition of volume in strategic locations, using facial fillers or a fat transfer. This approach offers outstanding outcomes, including a rejuvenated and more youthful face, eyes and neck, as well as longer-lasting results.

As your face ages, several changes take place. Years of facial movements lead to wrinkles, the skin loses elasticity, and the face loses volume due to fat atrophy and bone resorption. The combination of all these factors results in looser skin, deflation, lax tissue, with more wrinkles and lines. When it comes to facial rejuvenation, the best treatment for you depends on the amount of volume loss you have experienced. In some cases, a facelift and/or necklift alone is enough to significantly improve the contour of the face. However, when a patient has loose skin and volume loss, we can achieve much better results by combining the facelift with volume enhancement.

A few of the procedures used in conjunction with a facelift or necklift are:

Is a Lift-and-Fill Facelift Right for You?

Good candidates for facelift surgery include individuals who are in good physical health, do not smoke or use nicotine, and desire correction of facial aging due to gravity or volume loss. The combination of a facelift and/or necklift with facial fillers or fat transfer can provide the stunning results you want. Contact Dr. John Burns today to schedule your consultation to learn more about short-scar facelift and the facial rejuvenation options that are right for you.

What if 0.2% of your skin cells determined its future? That was the question posed, and answered, by Dior as it strove for a breakthrough that would ultimately top anything the French beauty house and its scientific partners had achieved in 30 years of research and innovation.

For the first time, Dior used artificial intelligence to go beyond visible signs. It was thus able to measure what, up until now, was considered immeasurable the key to our perception of age: the faces visible health and vitality.

The result is what Dior calls a major discovery about stem cells, one so incredible that it has driven the creation of a new range focused on the restoration of cellular energy to reactivate the skins vital functions and youthful beauty.

The range is called Capture Totale C.E.L.L. Energy [the C.E.L.L. acronym stands for Cutting-Edge Long-Lasting Energy], a launch we reported earlier this month in a global exclusive. This special eZine edition of The Moodie Davitt Spotlight Series tells the story of how the new launch embodies all the values of Dior skincare, while taking the science behind it to a new level.

Its a remarkable story, which we are honoured to tell.

Note: The Moodie Davitt Report Spotlight Series offers bespoke, curated e-publications for major brand launches and campaigns; airport, store or restaurant openings; and other notable corporate or commercial developments, events and anniversaries.

Point blank: Aging is a part of life. With each passing second, minute, and day, we age a little bit more. While you may not notice the signs of aging right away, there will come a day when you look in the mirror only to notice 11s and crows feet staring back at you. Of course, if you implement a quality anti-aging skincare routine before then, it may be years before you notice such things.

Intrigued? We thought you might be. Thats why we tapped some of the industrys top dermatologists to share their top 10 anti-aging skincare ingredients. By committing these ingredients to memory and adding them into your routine, youll be able to pause the clock of visible aging while making way for your bounciest, most beautiful skin yet. You can thank us later.

While there are many anti-aging ingredients on the market, dermatologists share that the following 10 are the most effective for fast-acting results.

Alpha- and beta-defensins are natural immune proteins that have been shown in in vitro studies to activate stem cells in the hair follicle, which typically helps with wound healing of the skin, says Yunyoung Claire Chang, M.D., a board-certified cosmetic dermatologist. These defensins have been shown to be effective in a new skincare product, called DefenAge. One multi-center, blinded controlled trial published in the Journal of Drugs in Dermatology in 2018 evaluated 44 patients using this new skincare product, demonstrating that this product improves brown spots and skin evenness, improves the appearance of wrinkles, and reduces visible pores. She adds that the product has retinol-like effects without the inflammation associated with retinol.

Bakuchiol is well-known for being a gentle (yet effective) retinol alternative. These findings were confirmed in a 2014 study published in the International Journal of Cosmetic Science, where researchers found that bakuchiol was able to stimulate collagen production in vivo, and found that 12-week application improved texture, tone, photo-damage, and more. While it has many of the same benefits of retinol, Dr. Chang says the most notable quality is that bakuchiol has less of the drying and irritating side effects of retinol, while still being just as effective.

Youve likely seen ceramides called out on many of the labels on the skincare products already in your routine. Thats because ceramides are intensely hydrating and effective for anti-aging.

Ceramides are a natural lipid that helps protect our skin barrier and seal in moisture. As we mature, the ceramide levels in our skin decrease, leading to drier, more sensitive skin, Dr. Chang explains. Dry skin also worsens the appearance of fine lines and uneven skin texture. Replacing ceramides using topical skincare is important to keep it hydrated, protected, and smooth.

Ginseng might be considered a Korean superfood, but were here to let you in on a little secret: It works wonders topically for your complexion, as well. Panax ginseng and ginsenosides are promising in preventing skin aging, Dr. Chang explains. Ginseng extract has been found in studies to protect against UVB-induced skin aging, reduce wrinkles, and increase moisture in the skin. However, its worth noting that most ginseng skincare studies have been small and need to be corroborated with larger clinical trials.

Take it from someone with sensitive skin who loves a gentle exfoliation: Glycolic acid is an alpha hydroxy acid (AHA) gorgeous skin dreams are made of. Dr. Chang supports this notion, explaining that glycolic acid exfoliates the top layers of the skin to improve texture and tone. Glycolic acid also has additional anti-aging benefits, including fighting UV-induced inflammation, lightening brown spots, and stimulating collagen, she adds. With glycolic acid, the higher the concentration of the product, the stronger its effects (and side effects). As such, its best to leave the higher concentrations of glycolic acid for professional use during in-office facials and treatments.

In some cases, glycolic acid (despite being fairly gentle) can be too irritating for super-sensitive skin. In these cases, you can reach for lactic acid, another AHA thats effective at resurfacing the skin.

Green tea might be a super popular beverage, but its also a stellar choice for reversing the clock on your complexion. According to Dr. Chang, green tea is an abundant source of polyphenols that can help protect the skin against UV-induced skin aging and skin cancer. It has antioxidant, anti-inflammatory, and anti-wrinkle properties, she adds.

Niacinamide, also known as vitamin B3, is a water-soluble vitamin that has been shown to have anti-inflammatory and anti-aging properties, Dr. Chang explains, noting that it helps calm red, inflamed, or irritated skin. Whats more, the hydrating ingredient helps protect the lipid barrier and keep the moisture barrier intact which helps heal dry skin and prevent seasonal flaking. It has also been shown to increase collagen production as well as inhibit melanosome transfer from melanocytes to keratinocytes, allowing lightening of dark spots, Dr. Chang adds. In other words, its a multi-tasker that deserves a spot in your anti-aging routine.

Retinoids are a derivative of vitamin A and are one of the longest-studied anti-aging ingredients. Retinoids have a long track record and clinical studies since the 1980s to back its evidence for preventing and treating skin aging, Dr. Chang explains. Retinoids increase skin cell turnover, diminish brown spots, and stimulate collagen to prevent fine lines and wrinkles.

While retinoids are undoubtedly effective, its worth noting that some versions can cause dryness and irritation, especially for those with dry or sensitive skin. Therefore, its best to start with a low percentage retinol (like 0.025 percent) before working yourself up to a stronger dose, prescription retinoid or Retin-A (like 0.5 to 2 percent).

Even when starting off with low percentages, Dr. Chang points out that retinoids tend to be drying and irritating, especially with initial use. It is important to start slow, using a small pea-size amount over the face, she says. I recommend starting two or three times per week at nighttime, and increasing the frequency of use slowly as tolerated.

Additionally, Dr. Chang says that retinoids and glycolic acid, especially when used together, may cause excessive dryness and irritation. For that reason, its best to choose between the two instead of trying to use them simultaneously.

Sun protection is the most critical part of your anti-aging skincare routine, Dr. Chang emphasizes. Sun exposure not only causes skin burning and skin cancer but is the main culprit for accelerated skin aging. Whats more, she adds that UV exposure forms free radicals, increases brown spots, and breaks down collagen to form fine lines, wrinkles, and skin laxity. This process, termed photo-aging, is absolutely preventable with the appropriate use of sun protection and broad-spectrum sunscreen, she explains, noting that she recommends mineral sunscreens with SPF 30 or greater, including zinc oxide and titanium dioxide. Mineral sunscreens sit on the surface of the skin and act as a barrier to both UVA and UVB rays rather than being absorbed into the skin, she explains. Because it isnt absorbed into the skin, there is a lower risk of allergic reactions and it is safe in pregnant females.

And remember: Regardless of the sun protection you opt for, reapplication every few hours is key.

Vitamin C renowned for its powerful antioxidant properties and the ability to affect so many aspects of aging. For starters, adding vitamin C into your skincare routine can lead to a brighter complexion. Whats more, Dr. Chang points out that the potent ingredient can act as a free radical scavenger to neutralize oxidative damage to the skin and stimulate collagen for fine line prevention.

The biggest thing to remember when adding vitamin C to your anti-aging routine is that the ingredient is very unstable. As a result, its important to look for stabilized formulations found in opaque, air-tight bottles.

Dr. Chang also notes that some formulations of antioxidant serums containing vitamin C may irritate or cause acne for some people, so it is important to find which products work best for your skin. This may take some trial and error (or, better yet, the advice of a derm), but it will be well worth it in the long run.

Great! So now that you know which skincare ingredients to keep on your radar, heres what else you need to know about how to use them.

The anti-aging skin type debate:

After reading about these anti-aging ingredients, you might be wondering which will be best for your skin type. While some are better tolerated by some specific skin types (as mentioned above), its important to remember that skincare is subjective based on your skin type and the products already in your routine.

undefined

At the end of the day, she says its not so much the skin type as what you are trying to address. For example, retinoids help to rejuvenate at the cellular layer, she begins. Glycolic acids helps to increase cell turnover and exfoliation.

When to add anti-aging ingredients into your skincare routine:

As much as wed like to tell you exact dates down to the day as to when to incorporate these ingredients into your routine, thats simply not realistic given that skin aging is subjective and varies from person to person. However, considering all of these ingredients are preventative, Dr. Chang says that its best to start incorporating them before or shortly after you start to notice signs of skin aging. I recommend starting anti-aging skincare in your 20s or early 30s, she adds. Some of these ingredients can be started even earlier (i.e. retinoids in teenagers with acne).

How to add anti-aging ingredients into your skincare routine:

Now, we know what youre thinking: How hard could it be? Well, if you try to add all 10 of these ingredients into your routine at once, youll seeand it wont be pretty. Since these ingredients are active, its important to ease them into your routine to avoid any sort of adverse effects.

I always recommend starting anti-aging ingredients one by one, to avoid any skin reactions or excessive irritation, Dr. Chang says. Start with a test spot before applying new products over your whole face. If one anti-aging product is tolerated, you can slowly add another one into the regimen. Additionally, she notes that not every person needs to use all of these ingredients, as many of the benefits overlap and using too many products can sometimes do more harm than good. I recommend consulting your board-certified dermatologist to develop a skincare plan tailored to your skin needs, she says.

Head-to-toe anti-aging treatments:

If you, like us, are a big believer in the beauty of cosmetic anti-aging treatments, like lasers and injectables, you might be wondering if you should supplement your anti-aging skincare routine with these in-office offerings. Considering most topicals can only penetrate the top-most layers of skin (unless, of course, its an epigenetic formulation), opting for treatments geared towards underlying causes of expression can lead to more noticeable results. For example, board-certified dermatologistJennifer MacGregor, M.D., says that Botox can smooth crepey texture in addition to lines (on the chest, for example) and can also smooth neck bands (hi, tech neck)something a cream alone may not be able to do.

As we mature, we lose fat and collagen in our face, leading to loose, sagging or hollowed skin, says Chang. Filler injections can help replace this volume and collagen in areas where topical anti-aging products would have little to no efficacy. Additionally, she points out that brown spots and photo-aging are often due to deeper pigment deposits which topicals cannot reach. Laser treatments can more effectively lighten or eliminate brown spots and signs of photo-aging, she explains. Resurfacing laser treatments, like Fraxel dual, and skin tightening treatments, like Ultherapy, can go deeper than any topical can to stimulate collagen, making these treatments essential in the anti-aging process [from head to toe].

The day of the robot frog is here. Sort of. Researchers in the United States have taken stem cells from the tissue of African clawed frogs and put them together to build tiny living robots. These are the worlds first living machines, robots made from biological tissue that have advantages your run-of-the-mill plastic and metal robots dont have.

These lifeforms have never before existed on earth, Michael Levin, director of the Allen Discovery Center at Tufts University, which conducted the research alongside scientists from the University of Vermont, said. They are living, programmable organisms.

Researchers are calling these new creatures xenobots, derivedfrom Xenopus laevis, the scientific name for the African clawed frog. The botsare less than a millimeter wide, which is small enough to travel through thehuman body. And they dont look anything like the robots weve all seen before.Xenobots are basically tiny dollops of moving pink flesh.

According to CNN,the researchers took stem cells from frog embryos, left them to incubate, thenused a supercomputer to cut and shape the cells into body forms. For example,you can have a xenobot with a hole in the middle that could possibly be used todeliver medication inside the human body.

Once they were created, the robots operated on their own. Theskin cells bonded to form structure, and the heart cells would actually pulse,allowing the bots to propel themselves.

What else might the xenobots be used for? Scientists say theycould potentially be used to remove plaque from artery walls, locate anddestroy radioactive waste, and even clean up microplastic pollution in theoceans.

And although metal and plastic robots are strong and durable, there are good reasons to create bots from biological tissue. For one thing, the xenobots are self-healing. And once their task is complete, says The Guardian, they fall apart, just as natural organisms decay when they die. That makes them more environmentally friendly than traditional robots, as well.

Creating these xenobots does raise some ethical issues,particularly because future versions of them might actually have nervoussystems and cognitive abilities. And then what will they be, living creaturesor just machines?

Whats important to me, Sam Kriegman, a PhD student on the University of Vermont team, said, is that this is public, so we can have a discussion as a society and policymakers can decide what is the best course of action.

5 Ways To Stay Healthy If You Sit All Day At Work

Ever since the 1966 film 'Fantastic Voyage', an American science-fiction about a submarine crew who are shrunk to microscopic size and venture into the body of an injured scientist to repair damage to his brain, it remained a possible conception for robotic engineers too.

Now, a team of scientists from the University of Vermont has succeeded by repurposing living cells of frog embryos into entirely new millimeter-long life-forms, called "xenobots", which can move toward a target, carry a payload, say, a medicine and reache a specific body part of a patient.

"These are novel living machines," says Joshua Bongard, a computer scientist and robotics expert at the University of Vermont, part of the research team. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

Bongard says they tried to slice the robot almost in half and found it stitching itself back up and moving ahead. This is "somtheing you can't do with typical machines. These xenobots are fully biodegradable. When they're done with their job after seven days, they're just dead skin cells," explained Bongard.

Initially designed on a supercomputer and then assembled and tested by biologists at Tufts University, these robots can have many useful applications as first batch of living robots that other machines cannot become, said Michael Levin, team member and director of Center for Regenerative and Developmental Biology at Tufts.

Some of the applications include searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque. The results of the new research were published January 13 in the Proceedings of the National Academy of Sciences.

The team used an evolutionary algorithm to create thousands of candidate designs for the new life-forms, which can carry out a task like locomotion in one direction. First they gathered stem cells, harvested from the embryos of African frogs, the species Xenopus laevis, which led to its name "xenobots."

Assembled into body forms never seen in nature, the cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion and aided by spontaneous self-organizing patterns -- allowing the robots to move on their own.

Later, tests showed that groups of xenobots would move around in circles, pushing pellets into a central location -- spontaneously and collectively. "It's a step toward using computer-designed organisms for intelligent drug delivery," says Bongard.

Formosa's plastics plant is seen dominating the landscape in Point Comfort, Texas. Julie Dermansky / DeSmogBlog

Diane Wilson is seen with volunteers before their meeting across the street from Formosa's Point Comfort manufacturing plant. Julie Dermansky / DeSmogBlog

Within 10 minutes she collected an estimated 300 of the little plastic pellets. Wilson says she will save them as evidence, along with any additional material the group collects, to present to the official and yet-to-be-selected monitor.

Wilson received the waiver forms from Formosa a day after the deadline. The group planned to set out by foot on Jan. 18, which would allow them to cover more ground on their next monitoring trip.

Any nurdles discharged on or after Jan. 15 in the area immediately surrounding the plant would be in violation of the court settlement.

Lawsuit Against Formosas Planned Louisiana Plant

On that same afternoon, Wilson learned that conservation and community groups in Louisiana had sued the Trump administration, challenging federal environmental permits for Formosa's planned $9.4 billion plastics complex in St. James Parish.

The news made Wilson smile. "I hope they win. The best way to stop the company from polluting is not to let them build another plant," she told me.

The lawsuit was filed in federal court against the Army Corps of Engineers, accusing the Corps of failing to disclose environmental damage and public health risks and failing to adequately consider environmental damage from the proposed plastics plant. Wilson had met some of the Louisiana-based activists last year when a group of them had traveled to Point Comfort and protested with her outside Formosa's plastics plant that had begun operations in 1983. Among them was Sharon Lavigne, founder of the community group Rise St. James, who lives just over a mile and a half from the proposed plastics complex in Louisiana.

Back then, Wilson offered them encouragement in their fight. A few months after winning her own case last June, she gave them boxes of nurdles she had used in her case against Formosa. The Center for Biological Diversity, one of the environmental groups in the Louisiana lawsuit, transported the nurdles to St. James. The hope was that these plastic pellets would help environmental advocates there convince Louisiana regulators to deny Formosa's request for air permits required for building its proposed St. James plastics complex that would also produce nurdles. On Jan. 6, Formosa received those permits, but it still has a few more steps before receiving full approval for the plant.

From the Gulf Coast toEurope

Just a day after Wilson found apparently new nurdles in Point Comfort, the Plastic Soup Foundation, an advocacy group based in Amsterdam, took legal steps to stop plastic pellet pollution in Europe. On behalf of the group, environmental lawyers submitted an enforcement request to a Dutch environmental protection agency, which is responsible for regulating the cleanup of nurdles polluting waterways in the Netherlands.

The foundation is the first organization in Europe to take legal steps to stop plastic pellet pollution. It cites in its enforcement request to regulators Wilson's victory in obtaining a "zero discharge" promise from Formosa and is seeking a similar result against Ducor Petrochemicals, the Rotterdam plastic producer. Its goal is to prod regulators into forcing Ducor to remove tens of millions of plastic pellets from the banks immediately surrounding its petrochemical plant.

Scientists Combine AI With Biology to Create Xenobots, the World's First 'Living Robots' - EcoWatch

Skin Stem Cells Comments Off on Scientists Combine AI With Biology to Create Xenobots, the World’s First ‘Living Robots’ – EcoWatch | January 22nd, 2020

Over the last three decades, Ken Aldrich has successfully invested in over 50 businesses and has personally co-founded almost a dozen himself. He considers himself a jack of all trades, having been involved in everything from biomedicine to real estate. Some of his most successful investments include helping start one of the first wind parks in Palm Springs and Green Dot Corp. (NYSE:GDOT), which has become the worlds largest prepaid debit card company. In May, Aldrich published his book, "Dream Toolbox," which aims to guide readers toward establishing an entrepreneurial mind and gaining control over their financial world.

Before the business

Prior to entrenching himself as an entrepreneur, Aldrich started his career as a wage earner practicing law. He spent a great deal of time and effort to earn his law degree and land a spot in a well-established firm. With a clear career path ahead of him, Aldrich got to work earning his keep and establishing his position in the firm. However, one definitive moment stands out as the time when he became dissatisfied with his work.

This moment would revolve around sandwiches of all things. Working alongside one of the senior partners at the firm, Aldrich was helping to create a registration statement for a public company. At the end of the session that fateful day, the underwriters and the people from the company headed out to get dinner:

At the end of the day the company and the firm that was doing the underwriting turned to us, the lawyers, and said Well that was really good. Can we have a new draft of the work in the morning at nine and we will start again? Off they went to have dinner at Chasens and we ordered sandwiches, Aldrich said.

To provide context for those who do not know the Los Angeles restaurant history, Chasens was a well-known restaurant that was often frequented by famous celebrities until its closing in 1995. Based upon the prestige of the restaurant's chili, it is easy to conceive a distaste for sandwiches after a long day at work.

While in his 20s Aldrich did not have an issue eating sandwiches, yet he was thinking toward his future. My partner, that I was working for, was in his 30s or 40s. I do not want to be the guy eating sandwiches in his 30s or 40s, and I do not care how much they pay me for it, Aldrich said. It was in this moment that he decided that he would much prefer to be the guy going out for a nice dinner after work.

With clear motivation, Aldrich set out to find himself a new career path. He landed himself a contractual position at an investment banking firm. This provided him with some needed experience and training, alongside a foot in the door with a name behind him. This new venture would come with an inherent risk, one that Aldrich would feel almost immediately.

Working at the law firm, he had earned himself a paycheck and a solidified position. Upon leaving, that paycheck disappeared. To compound the pressure, Aldrich was working on a contract for the investment banking firm, meaning that if he were to no longer be productive in their eyes, he would be cut from their team. In essence, the already large pay cut he had taken could go away in an instant. He went on to say:

Wide World of Sports had a sports program on Saturday and their opening montage was a skier, it might have been a tobogganer, coming down a ski run and losing control and flying head over heels into a snowbank. The tagline was Wide World of Sports, the thrill of victory and the agony of defeat. I realized that with conventional jobs you are either working for a paycheck or in the case of a lawyer you are measuring your life out in coffee spoons as Eliot once said in a poem. There is never the chance of a real thrill of victory. The expectation is do not screw up and I wanted something more than that.

Finding success

With a drive to succeed and find that thrill of victory, Aldrich set out on his journey to become a successful entrepreneur. By nature of the business, he would find himself in the world of seed stage venture capital, investing and co-founding businesses from the ground up. Through both luck and skill, he was able to grow many of these businesses to success, yet there is seemingly no connection between them. However, Aldrich considers himself a jack of all trades and finds that his curiosity has led him to such diverse portfolio.

While he has found himself invested in many different fields, there is one key factor that ties them all together. If there is technology involved, I want to make sure that if it is successful, often it is not completely developed when we start, but that if it is successful it will make a fundamental change in some business, or industry, or science, Aldrich said. Having this significant change in the way things are done makes either the business or the product stand out in a way that the market cannot deny. For Aldrich, this is key for these types of ventures to be a success.

It is very hard to be successful starting a new business if you are just doing it a little bit better because, you know, everybody is looking for perfect, but perfect is the enemy of the good. If there is an existing process that is serving the market adequately it is usually just a fools errand to try to make something else that is just a little bit better, he continued.

As with many lessons, Aldrich had to learn to make fundamental changes first hand. One of the first businesses he found himself involved in was working to develop a new device for LASIK procedures. This device would allow for the surgeon to be more accurate when applying the procedure. Initially, the company found success in that the device did improve the accuracy of the procedure. However, it was not a big enough difference and nobody cared according to Aldrich.

Going back to the drawing board, the company went about redesigning the product so that it could be an aid to curing amblyopia in children, yet the market there was too small. With the aid of an ocular physician, the company found its true purpose. The new design would allow a surgeon in the process of doing cataract surgery to take an accurate measurement of the eye.

Prior to this new design, the surgeon would attempt to measure the eye through the clouded portion as best as possible before removing the affected area. As the measurement had to be taken through the affected area, it was generally not overly accurate and that is how people ended up with those coke bottle glasses, Aldrich said.

With their newly pioneered technology, the surgeon had a new device that would attach to the microscope that they used during the procedure. This would allow for them to take an accurate measurement of the lens of the eye prior to the surgery. This technology resulted in vision on par with a LASIK procedure as a byproduct of conventional cataract surgery. It was very gratifying for me because I have, over my life, had enough eye problems to realize just how life changing that small procedure can be, Aldrich said. This business would eventually go on to sell for $350 million.

Managing risk

With the prospect of millions, if not billions, on the horizon, there is constant risk involved with starting these businesses. For Aldrich, the key to success comes in managing this risk, although it can never be entirely eliminated. Once he has established that the technology or the business will make a fundamental change in the industry it operates in, he looks toward the people involved. First and foremost, he questions if they have enthusiasm and skin in the game as he calls it. Now that does not necessarily mean that they have written big checks, but they have put some portion of their life on hold to pursue this, he said.

Finding a person who fits these qualities allows for Aldrich to be confident that if things get difficult with the company, nobody is going to give up. In many cases, things do go wrong when starting a business. Very rarely does a business make its way to success without encountering a road bump. At some point everyone has to take some genuine risk. I have never known a startup that did not involve that, Aldrich said.

Over the course of 30 years in business, Aldrich has experienced his fair share of risk and road bumps. One of the most egregious cases that he recalled involved a biotechnology company. The company in question was working to develop new stem cells similar in nature to embryonic stem cells. The winning factor was that the company had found a way to access these cells without needing a fertilized embryo. So we took all, or we thought we took all of them, some people still managed to find objections, but we took basically all the real objections away from those who were concerned, for religious or for other reasons, with whether or not using embryonic stem cells was in effect killing a human being in utero, Aldrich said.

While they had overcome a major roadblock to progress their research, they still had not reached calm seas. The company would go public and found itself in the midst of the economic downturn of 2008. Almost overnight, funding that had been promised had disappeared and the company was left stranded with no backing.

To further compound issues, the CEO of the company died of a heart attack shortly after. Aldrich found himself running the company and as an investor himself. He put forth a check for $500,000, one that would have been very painful to have lost in his own words. In a stroke of luck, he was able to find an investor for the company. However, the man was in Paris, was Russian and spoke no English. Not a man to be stopped, Aldrich flew to Paris, dug up a translator on the eve of a French holiday and made a deal with the new investor.

With the help of this new partner and his own investment, Aldrich would pull the company out of the hole it found itself in. The company would continue to make progress on its stem cell research. Eventually, the majority shareholder of the company would push Aldrich out of a leadership position and he decided it would be best to pull himself out of the company entirely. During his time there, Aldrich would grow the stock from 15 cents per share to over $2 per share.

The biggest perks

While Aldrich has undoubtedly seen rough times working with companies, he has found himself, more often than not, in the position of successfully creating a business. The thrill of just saying, I did that, claimed Aldrich, is one of the best parts of what he does. Continuously, he has had the ability to take the vision that someone brings him and help them turn it into a reality. For him that has been extremely gratifying, yet he has been able to take it one step further.

Many of the companies that he has been involved in have changed people's lives for the better. The first LASIK company aided many people in having better vision, which Aldrich considers life changing. The stem cell company has the potential to change the way stem cells are used, and he believes they ultimately will. Even present day he is working with a company that is working to make chemotherapy drastically more effective to the point that it can cure certain types of cancers.

Without a doubt Aldrich has found the thrill of victory and helped people in the process. Now it is still a whole lot of fun to make money from a deal and see it take off, he said. One of his most ludicrous investments was Green Dot Corp., in which he was an early investor. Since throwing his hat in the ring, the company has not only reached a billion-dollar market cap, it has created an entirely new industry of prepaid debit cards.

Even the wind park in Palm Springs that Aldrich helped start has seen him cashing monthly checks from land rights for the last 20 years. Having both built companies and earned money for decades, it is easy to understand how he has no desire to change anything, yet Aldrich believes that he has no regrets for a different reason.

I think in each case we did the most we could do with what we had available, Aldrich said. In his opinion, there will always be something that could have gone differently or a potential to have found greater success. The reality is I had gone everywhere I could think of and took the option that was available, he continued.

In the end, worrying becomes unproductive. It creates a situation in which you are cautious about your current ventures and begin to question every decision. Aldrich believes this type of fear, the fear of failure, is one that is extremely detrimental to an entrepreneur. Overcoming this fear has been key to his success.

No end in sight

In his most recent ventures, Aldrich has found himself seeking to inspire both youth and entrepreneurs alike. He has spent time working with at-risk teenagers to provide them with financial lessons as well as the skills to develop their dreams into reality. From these lessons, Aldrich developed a podcast series that would eventually become his first book, titled "Dream Toolbox," for anyone frustrated by unfulfilled dreams.

Although Aldrich has had a career outlasting many other entrepreneurs, he does not believe he will ever be able to stop. While he has made a promise to himself to not start any new companies, he will continue to fund and advise them as much as he can:

I can not see stopping because, frankly, it is so darn much fun. I have flunked retirement several times in the sense of really trying to turn it off. What I have discovered is just about the time I am getting all excited to go play a round of golf, or go play tennis or something like that, somebody will call me up with a new idea, or a new concept, and I will cancel the golf or cancel the tennis because nothing is more exciting than dealing with a new idea that has great promise.

Question and answer

GuruFocus: As an entrepreneur, and a serial entrepreneur at that, is there anything in the future coming up or already starting to reach the market that you are really excited about and would love to get your hands on?

Aldrich: My experience has been that the things that are already visible to me, out there in the market, somebody else has already started and is way ahead of me. So what I am looking for are the things that are not yet obvious and those can come in many ways. I recently became an investor in a company. It is not a startup anymore. I invested through some friends, but it is very exciting. They have, I believe, a way to, I will not say cure, but to take any of the existing chemotherapies that are used in cancer and make them way, way more effective, and the reality is, based upon the data we have, in many cases cure cancers that the physicians had given them up as incurable and a death sentence. That is enormously exciting to me and I think that we will see that.

I have also invested, although I am not a principle, in three or four other companies that have varying ways of approaching, particularly cancer, but other disease forms. That to me is an exciting area and I think we are just beginning to scratch the surface of what can be done medically. There are things going on with AI that will affect the medical world. I read in this mornings newspaper about a new AI technique that I think was developed by Google that has greatly improved the accuracy, or looks like it has greatly improved the accuracy of mammograms. That could be life-saving.

GuruFocus: Where do you look for inspiration?

Aldrich: One of the great books and it is overlooked, but I think everybody should read it right after they finish mine, actually before, is "Think and Grow Rich." Which has been around for almost a century, I guess. It is absolutely a brilliant set of ideas and structures for entrepreneurship. There are certainly more modern books. I happen to like Peter Thiels book, which I think he calls "Zero to One." It talks about entrepreneurship and finding a niche that you can fill and expand into making something big. Of course, if you just start looking and get specific, there are tons and tons of books on how to structure a business, how to handle the accounting, finance and so on. Again, I think it starts with changing the belief systems so that you believe you can do it and for that there probably is no better book that I have read than "Think and Grow Rich."

GuruFocus: What are you most grateful for at this point in your life?

Aldrich: Oh wow. I am most grateful that I have had the incredible good fortune to have the love of not one, but two wonderful women in my life. First my wife, who died a few years ago, and second, the woman who is now sharing my life. That has been remarkable. I have also had the good fortune through most of my life of having good health. I have had plenty of health issues that I have had to deal with, but they have all been like the puzzles I talked about. OK, I have a problem. I had a vision problem. I have had other things. How can we solve them? So far, they have all been soluble. I have been very fortunate. As you can see from this ugly photograph on your screen, I am not a young man anymore. I wake up in the morning thinking I am at least 20 or 30 years younger than I am until I look in the mirror. And that is a good thing because age ultimately matters as none of us live forever. In terms of our capacity to do things, it is how we view ourselves, so that is important.

Aldrichs advice for entrepreneurs

Have a vision both personally and in business:

Try to visualize what life would look like if you were to find the success that you have. Once you have this vision, there is something for you to strive for. In Aldrichs opinion, this is one of the most powerful tools an entrepreneur can utilize. Visualize yourself being successful while standing in front of the mirror. It may feel stupid at first, as it did for Aldrich, but you will eventually make that vision a reality by translating it into the present. Use your vision to tell yourself that you are successful now and, before you realize it, you will have reached many of your early milestones.

Put some skin in the game:

It can be simplified to one word: commit. You need to absolutely dedicate yourself to what you are doing if you want to succeed. This will require personal sacrifice. Your life will not continue to exist in the same way that it had previously and you have to be OK with that. Once you have committed your life to achieving your goals and truly put some skin in the game, you will find success. If you do not do this, you are going to give up when things get tough.

Determine if the worst outcome is survivable:

Another of Aldrichs most powerful tools is determining if the worst possible outcome is survivable. Look at the worst thing that could happen in the course of starting this business. Are you looking at bankruptcy? Or could it be something personal that ends life as you know it? Once you have determined what could happen, you need to decide if you have the ability to keep going on after that. If you can survive the worst outcome, than there is nothing that can stop you on your journey. All your problems become puzzles that have a solution. You simply need to find it.

Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Global Stem Cell Therapy Market: Market Potential

A number of new studies, research projects, and development of novel therapies have come forth in the global market for stem cell therapy. Several of these treatments are in the pipeline, while many others have received approvals by regulatory bodies.

The birds and the bees as we know them are changing. A new process called in vitro gametogenesis (IVG) is currently being developed, and if successful, it will completely transform the way humans think about reproduction.

In 20 to 40 years, people will still have sex. But when they want to make babies, theyll go to a lab, predicts Stanford University Professor Henry T. Greely. Its also the premise of his book The End of Sex and the Future of Human Reproduction.

The process of IVG creates sperm and egg cells in a lab from just about any adult cell. IVG uses skin or blood cells to reverse engineer a special type of cells calledinduced pluripotent stem cells(iPSCs).

IVG could eliminate the need for egg and sperm donors. With IVG, post-menopausal women could generate viable eggs. Same-sex couples could make a biological family. Virtually anyone with skin would have the ability to produce eggs or sperm.

Although 40 years might seem a lifetime away, theres a lot to figure out before we can safely, ethically, and responsibly add in vitro gametogenesis to our list of fertility treatment options.

No more feeling self-conscious about your scarring.

But there are other ingredients that aren't as harsh on the skin.

Salicylic acid is a fabulous way to combat acne in all skin types and can be found in a wash or in a lotion. If you tend to get small acne bumps known as comedonal acne, try OTC Differin lotion which is a retinoid. In general, those are strong enough to cause the skin to purge out those small bumps (which means it will be a little worse before getting better), and then prevent them from recurring, adds Dr. Mariwalla.

Contrary to what some people may think, having acne still means you need to moisturize. However, there are some precautions to consider. According to Dr. Mariwalla,Be sure not to use a heavy cream. Try a moisturizing gel or even a serum. A hyaluronic acid serum is ideal for acne=prone skin because it wont typically make you break out.

An international collaboration called BioRescue has taken a step forward in bringing back the Northern White Rhino with the creation of three embryos, which it hopes to bring to term in a surrogate in the coming months.

The BioRescue team, including researchers based at the Leibniz Institute for Zoo and Wildlife Research, Germany, extracted egg cells from the ovaries of the last two remaining northern white rhino females. They then artificially fertilized the eggs using sperm taken from now-deceased male rhinos and stored the embryos in liquid nitrogen. The team managed to create two embryos in September 2019 and has recently created a third.

Before the BioRescue team came, no one had ever created an embryo from a northern white rhino except for the rhino itself, Steven Seet, Head Public Relations & International Affairs at the Leibniz Institute for Zoo and Wildlife Research, told me. This species is functionally extinct. Nevertheless, we have achieved the production of a third embryo now. This is incredible.

As the last two females are unable to become pregnant, the plan now is to implant the embryos into surrogate female southern white rhinos, a distinct subspecies, in the coming months. Every additional embryo increases the probability of getting a pregnancy The more, the better! Seet said.

There are many technical challenges remaining before the team can save the Northern White Rhino from extinction. First of all, it will need a lot more than three embryos to rebuild a healthy population. To meet this challenge, the team is developing technology to transform stem cells from northern white rhino skin tissue into egg and sperm cells. Our Japanese cooperation partner succeeded in doing so in a mouse model, Seet said. We are adapting this to the rhinos.

A second challenge may lie in implanting a northern white rhino embryo into a surrogate southern white rhino mother, which might have compatibility issues.

It might be that there are epigenetic components involved as the biological system of the southern rhinos might differ from the northern, Seet told me. A possible assessment of this could be conducted when we have the first calves on the ground. This is further research then.

Also involved in the BioRescue project was the German big pharma Merck KGaA, which donated a specialized incubator where the egg cells could be fertilized with monitoring by HD cameras.

Merck has donated access to its innovative fertility technologies to Project BioRescue to give this challenge the best possible chance of success and protect the Northern White Rhino from extinction, Jan Kirsten, Mercks Head of Global Business Franchise for Fertility, told me. While there is a long way to go on this journey, we hope these steps will pave the way for this technique to potentially be used in other species.

According to Kirsten and Seet, the biotechnology industry will likely play a strong role in the conservation of endangered species in the coming years. However, argued Seet, reproductive medicine and stem cell technology should remain a last resort to save a species.

It would be better to react much earlier to avoid using the BioRescue technology, he said. Humans must learn from this best practice project and evaluate biodiversity and conserve it.

WASHINGTON - Scientists in the United States created the first living robots using stem cells, which can move toward a target and heal themselves after being cut. A study published on Monday in Proceedings of the National Academy of Sciences described the living, programmable organism, a completely new biological machine designed from ground up. Scientists at the University of Vermont ran an evolutionary algorithm on a supercomputer to screen out a design to be composed of single frog skin and heart cells.

Then, scientists at Tufts University transferred the in silico design into life with stem cells harvested from embryos of African frogs. They used tiny forceps and electrode to assemble the single cells into a close approximation of the computer designs.

They found that the skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion, allowing the robots to move on their own.

Those millimeter-wide reconfigurable organisms were shown to be able to move and explore their watery environment for days or weeks, according to the study.

They could move around in circles, collectively pushing pellets into a central location. Its a step toward using computer-designed organisms for intelligent drug delivery, said Joshua Bongard, a computer scientists at the University of Vermont.

We can imagine many useful applications of these living robots that other machines cant do, said Michael Levin at Tufts University, like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque.

In another test, the scientists cut the living robots and watched what happened. We sliced the robot almost in half and it stitches itself back up and keeps going, said Bongard.

Right now, your bodys stem cells are working hard replacing your skin every two weeks, creating new red and white blood cells and completing thousands of other tasks essential to life. They are your own personalized fountain of youth.

Scientists generally agree that a stem cell should be able to do both of the following:

One theory of ageing suggests that between the ages of 30 and 50, our stem cells reach a turning point and start to decline in number and function. This results in the typical features associated with ageing.

There does not seem to be a single discoverer of stem cells. Accounts date back to the 1800s and even further, but the first successful medical procedure was a bone marrow transfusion in 1939. Advances in immunology led to donor matching, initially via siblings and close relatives. Unrelated donor matching flourished in the 1970s, alongside donor registries.

In the 1980s, scientists identified embryonic stem cells in mice, leading to the 1997 cloning of Dolly the Sheep. This created immense interest for human and medical applications and a backlash in the US as federal R&D funding was essentially halted in 2001.

In 2012, a Nobel Prize was awarded for the earlier discovery of induced pluripotent stem cells (iPS). Essentially, they return potency and self-renewal properties to mature non-stem cells, essentially making them act like stem cells again.

In the decade between 2010 and 2019, the first wave of stem cell start-ups emerged, alongside R&D programmes at many large pharmaceutical companies, leading to innovation and the first human clinical trials for iPS and other related therapies.

According to Q3 2019 data from the Alliance for Regenerative Medicine, there are 959 regenerative medicine companies worldwide sponsoring 1,052 active clinical trials; 525 of these companies are in North America, 233 in Europe and Israel, and 166 in Asia. In aggregate, $7.4 billion has been invested in regenerative medicine companies in 2019; $5.6 billion of which has been dedicated to gene and gene-modified cell therapy, $3.3 billion in cell therapy, and $114 million in tissue engineering.

Overview of the cancer stem cells market

Perhaps most excitingly, curative therapies are hitting the market and the results are astonishing: 60% of Acute Lymphoblastic Leukemia patients taking Novartis Kymirah showed a complete response (no traces of cancer) and were declared in full remission. Meanwhile, 75% of patients with Transfusion-Dependent -Thalassaemia treated with bluebird bios Zynteglo achieved independence from transfusions. Perhaps most astonishingly, 93% of spinal muscular atrophy patients treated with Novartis Zolgensma were alive without permanent ventilation 24 months after treatment. We should expect more medical breakthroughs in the coming years.

New science, new start-ups: several companies in the sector have gone public or been acquired. These exits led to the recycling of talent and capital into new companies. Because the science and commercial systems have also advanced, the companies in the next wave are pursuing bigger challenges, driving innovation, with even greater resources.

Patients are eager: the current market for stem cell therapies is growing at 36% per year, though it will rapidly expand when a breakthrough occurs toward the treatment of a non-communicable disease (such as cancer, diabetes, heart disease) or a lifestyle factor (for example, growing hair in the correct places, expanding cognitive abilities or increasing healthy lifespan).

New R&D models: funding is flowing into the sector from large companies, VC funds, and institutions such as the California Institute for Regenerative Medicine (CIRM) and New York State Stem Cell Science programme (NYSTEM). Some of the leading university R&D platforms include the Center for the Commercialization of Regenerative Medicine in Toronto, the Stanford Institute for Stem Cell Biology and Regenerative Medicine, the Oxford Stem Cell Institute, and most notably, the Harvard Stem Cell Institute (HSCI).

Founded in 2004, HSCI has established a phenomenal track record. It provided the first $200,000 in funding to Derrick Rossis lab, which inspired the largest biotech IPO to date. HSCI scientists were also co-founders or principals in the three most prominent gene-editing companies (CRISPR Tx, Intellia and Editas), the combined $1.55-billion True North/iPierian acquisitions and the recent $950-million acquisition of Semma Tx, Frequency Tx, Fate Tx, Epizyme Inc., and Magenta Tx.

For the casual investor, Evercore ISI is building a Regenerative Medicine Index, which may be the simplest way to build a portfolio. For institutions and those with deeper pockets, regenerative medicine funds are forming, including the Boston-centric Hexagon Regenerative Medicine Fund, which aims to create companies out of the Harvard Stem Cell Institute.

Caveat emptor. Though patients needs are immediate, those seeking treatments should think very carefully about the risks. There are many dubious clinics touting expensive stem cell treatments and some patients have experienced horrifying complications. Dr. Paul Knoepfler of UC-Davis has written a practical and scientifically accurate guide, a strongly recommended read if you or a family member are considering treatment or a clinical trial.

The leading causes of death in 1900 were mostly infectious/communicable diseases. While the prevalence of most causes has diminished, the largest increases include heart disease (+40%) and cancer (+300%). Granted, this is partly due to doubling life expectancy and a lack of death from other causes. However, given time and resources, scientists and physicians may cure these challenging diseases.

Total disease burden by disease or injury

Today, six of the seven leading causes of death are non-communicable diseases (heart disease, stroke, lung diseases, cancer, Alzheimers disease and diabetes). Based on the early promise mentioned above, regenerative medicine may be our best hope to solve the great non-communicable diseases of our time, and perhaps the single most transformative medical innovation in a century.

Why stem cells could be the medical innovation of the century - World Economic Forum

Skin Stem Cells Comments Off on Why stem cells could be the medical innovation of the century – World Economic Forum | January 17th, 2020

What happens when you take cells from frog embryos and grow them into new organisms that were "evolved" by algorithms? You get something that researchers are calling the world's first "living machine."

Though the original stem cells came from frogs the African clawed frog, Xenopus laevis these so-called xenobots don't resemble any known amphibians. The tiny blobs measure only 0.04 inches (1 millimeter) wide and are made of living tissue that biologists assembled into bodies designed by computer models, according to a new study.

These mobile organisms can move independently and collectively, can self-heal wounds and survive for weeks at a time, and could potentially be used to transport medicines inside a patient's body, scientists recently reported.

Related: The 6 Strangest Robots Ever Created

"They're neither a traditional robot nor a known species of animal," study co-author Joshua Bongard, a computer scientist and robotics expert at the University of Vermont, said in a statement. "It's a new class of artifact: a living, programmable organism."

Algorithms shaped the evolution of the xenobots. They grew from skin and heart stem cells into tissue clumps of several hundred cells that moved in pulses generated by heart muscle tissue, said lead study author Sam Kriegman, a doctoral candidate studying evolutionary robotics in the University of Vermont's Department of Computer Science, in Burlington.

"There's no external control from a remote control or bioelectricity. This is an autonomous agent it's almost like a wind-up toy," Kriegman told Live Science.

Biologists fed a computer constraints for the autonomous xenobots, such as the maximum muscle power of their tissues, and how they might move through a watery environment. Then, the algorithm produced generations of the tiny organisms. The best-performing bots would "reproduce" inside the algorithm. And just as evolution works in the natural world, the least successful forms would be deleted by the computer program.

"Eventually, it was able to give us designs that actually were transferable to real cells. That was a breakthrough," Kriegman said.

The study authors then brought these designs to life, piecing stem cells together to form self-powered 3D shapes designed by the evolution algorithm. Skin cells held the xenobots together, and the beating of heart tissue in specific parts of their "bodies" propelled the 'bots through water in a petri dish for days, and even weeks at a stretch, without needing additional nutrients, according to the study. The 'bots were even able to repair significant damage, said Kriegman.

"We cut the living robot almost in half, and its cells automatically zippered its body back up," he said.

"We can imagine many useful applications of these living robots that other machines can't do," said study co-author Michael Levin, director of theCenter for Regenerative and Developmental Biologyat Tufts University in Massachusetts. These might include targeting toxic spills or radioactive contamination, collecting marine microplastics or even excavating plaque from human arteries, Levin said in a statement.

Creations that blur the line between robots and living organisms are popular subjects in science fiction; think of the killer machines in the "Terminator" movies or the replicants from the world of "Blade Runner." The prospect of so-called living robots and using technology to create living organisms understandably raises concerns for some, said Levin.

"That fear is not unreasonable," Levin said. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences."

Nevertheless, building on simple organic forms like the xenobots could also lead to beneficial discoveries, he added.

"If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules," Levin said.

The findings were published online Jan. 13 in the journal Proceedings of the National Academy of Sciences.

World's First 'Living Machine' Created Using Frog Cells and Artificial Intelligence - Livescience.com

Skin Stem Cells Comments Off on World’s First ‘Living Machine’ Created Using Frog Cells and Artificial Intelligence – Livescience.com | January 16th, 2020

Scientists have created the worlds first living robots out of frog stem cells, according to new research. These tiny new lifeforms can be programmed to move around or carry and deliver miniature payloads that could one day be medicines inside a patients body, the Guardian reports.

The scientists knit skin and heart cells scraped from the embryos of African clawed frogs (Xenopus laevis) into 3D shapes designed by artificial intelligence to accomplish certain tasks.

These are entirely new lifeforms. They have never before existed on Earth, study co-author Michael Levin told the Guardian. They are living, programmable organisms.

The living robots, called xenobots after the clawed frogs Latin name, measure 0.04 inches and have enough energy inside them to keep moving for seven to 10 days before calling it quits.

The squishy robots dont have the strength and durability of plastic or metal machines, but biology affords them some unique advantages. They can heal themselves if wounded, and when their biological engines run out of fuel the xenobots simply fall apart and decay. This last part is crucial when it comes to potential medical or environmental applications in which leaving behind shards of plastic or metal presents obvious problems.

The researchers said we cant know for sure what applications await the soft-bodied bots, but imagined uses including cleaning up microplastics in the ocean, digesting toxic materials at polluted sites or scooping plaque from inside human arteries. Apart from scooting around in petri dishes, the researchers also say tinkering with these living machines could help scientists better understand the software of life.

The first generation of xenobots are tiny, but the scientists say the plan is to scale up perhaps even to living robots with blood vessels and nervous systems that can live on dry land.

If the voice of Jeff Goldblums character from Jurassic Park is beginning to echo in the back of your mind, youre not alone: When youre creating life, you dont have a good sense of what direction its going to take, Nita Farahany, who studies the ethics of new technologies and was not involved in the study, told Smithsonian. Any time we try to harness life [we should] recognize its potential to go really poorly.

For their part, the creators of the xenobots acknowledged the potential ethical implications, but say its up to society and policymakers to decide what those might be.

I think theyd acquire moral significance only if they included neural tissue that enabled some kind of mental life, such as the ability to experience pain, ethicist Thomas Douglas told the Guardian. But some are more liberal about moral status. They think that all living creatures have interests that should be given some moral consideration. For these people, difficult questions could arise about whether these xenobots should be classified as living creatures or machines.

SCIENCE

Newswise A book is made of wood. But it is not a tree. The dead cells have been repurposed to serve another need.

Now a team of scientists has repurposed living cells--scraped from frog embryos--and assembled them into entirely new life-forms. These millimeter-wide "xenobots" can move toward a target, perhaps pick up a payload (like a medicine that needs to be carried to a specific place inside a patient)--and heal themselves after being cut.

"These are novel living machines," saysJoshua Bongard, a computer scientist and robotics expert at the University of Vermont who co-led the new research. "They're neither a traditional robot nor a known species of animal. It's a new class of artifact: a living, programmable organism."

The new creatures were designed on a supercomputer at UVM--and then assembled and tested by biologists at Tufts University. "We can imagine many useful applications of these living robots that other machines can't do," says co-leader Michael Levin who directs theCenter for Regenerative and Developmental Biologyat Tufts, "like searching out nasty compounds or radioactive contamination, gathering microplastic in the oceans, traveling in arteries to scrape out plaque."

The results of the new research were published January 13 in theProceedings of the National Academy of Sciences.

BESPOKE LIVING SYSTEMS

People have been manipulating organisms for human benefit since at least the dawn of agriculture, genetic editing is becoming widespread, and a few artificial organisms have been manually assembled in the past few years--copying the body forms of known animals.

But this research, for the first time ever, "designs completely biological machines from the ground up," the team writes in their new study.

With months of processing time on the Deep Green supercomputer cluster at UVM'sVermont Advanced Computing Core, the team--including lead author and doctoral student Sam Kriegman--used an evolutionary algorithm to create thousands of candidate designs for the new life-forms. Attempting to achieve a task assigned by the scientists--like locomotion in one direction--the computer would, over and over, reassemble a few hundred simulated cells into myriad forms and body shapes. As the programs ran--driven by basic rules about the biophysics of what single frog skin and cardiac cells can do--the more successful simulated organisms were kept and refined, while failed designs were tossed out. After a hundred independent runs of the algorithm, the most promising designs were selected for testing.

Then the team at Tufts, led by Levin and with key work by microsurgeon Douglas Blackiston--transferred the in silico designs into life. First they gathered stem cells, harvested from the embryos of African frogs, the speciesXenopus laevis. (Hence the name "xenobots.") These were separated into single cells and left to incubate. Then, using tiny forceps and an even tinier electrode, the cells were cut and joined under a microscope into a close approximation of the designs specified by the computer.

Assembled into body forms never seen in nature, the cells began to work together. The skin cells formed a more passive architecture, while the once-random contractions of heart muscle cells were put to work creating ordered forward motion as guided by the computer's design, and aided by spontaneous self-organizing patterns--allowing the robots to move on their own.

These reconfigurable organisms were shown to be able move in a coherent fashion--and explore their watery environment for days or weeks, powered by embryonic energy stores. Turned over, however, they failed, like beetles flipped on their backs.

Later tests showed that groups of xenobots would move around in circles, pushing pellets into a central location--spontaneously and collectively. Others were built with a hole through the center to reduce drag. In simulated versions of these, the scientists were able to repurpose this hole as a pouch to successfully carry an object. "It's a step toward using computer-designed organisms for intelligent drug delivery," says Bongard, a professor in UVM'sDepartment of Computer ScienceandComplex Systems Center.

LIVING TECHNOLOGIES

Many technologies are made of steel, concrete or plastic. That can make them strong or flexible. But they also can create ecological and human health problems, like the growing scourge of plastic pollution in the oceans and the toxicity of many synthetic materials and electronics. "The downside of living tissue is that it's weak and it degrades," say Bongard. "That's why we use steel. But organisms have 4.5 billion years of practice at regenerating themselves and going on for decades." And when they stop working--death--they usually fall apart harmlessly. "These xenobots are fully biodegradable," say Bongard, "when they're done with their job after seven days, they're just dead skin cells."

Your laptop is a powerful technology. But try cutting it in half. Doesn't work so well. In the new experiments, the scientists cut the xenobots and watched what happened. "We sliced the robot almost in half and it stitches itself back up and keeps going," says Bongard. "And this is something you can't do with typical machines."

CRACKING THE CODE

Both Levin and Bongard say the potential of what they've been learning about how cells communicate and connect extends deep into both computational science and our understanding of life. "The big question in biology is to understand the algorithms that determine form and function," says Levin. "The genome encodes proteins, but transformative applications await our discovery of how that hardware enables cells to cooperate toward making functional anatomies under very different conditions."

To make an organism develop and function, there is a lot of information sharing and cooperation--organic computation--going on in and between cells all the time, not just within neurons. These emergent and geometric properties are shaped by bioelectric, biochemical, and biomechanical processes, "that run on DNA-specified hardware," Levin says, "and these processes are reconfigurable, enabling novel living forms."

The scientists see the work presented in their newPNASstudy--"A scalable pipeline for designing reconfigurable organisms,"--as one step in applying insights about this bioelectric code to both biology and computer science. "What actually determines the anatomy towards which cells cooperate?" Levin asks. "You look at the cells we've been building our xenobots with, and, genomically, they're frogs. It's 100% frog DNA--but these are not frogs. Then you ask, well, what else are these cells capable of building?"

"As we've shown, these frog cells can be coaxed to make interesting living forms that are completely different from what their default anatomy would be," says Levin. He and the other scientists in the UVM and Tufts team--with support from DARPA's Lifelong Learning Machines program and the National Science Foundation-- believe that building the xenobots is a small step toward cracking what he calls the "morphogenetic code," providing a deeper view of the overall way organisms are organized--and how they compute and store information based on their histories and environment.

FUTURE SHOCKS

Many people worry about the implications of rapid technological change and complex biological manipulations. "That fear is not unreasonable," Levin says. "When we start to mess around with complex systems that we don't understand, we're going to get unintended consequences." A lot of complex systems, like an ant colony, begin with a simple unit--an ant--from which it would be impossible to predict the shape of their colony or how they can build bridges over water with their interlinked bodies.

"If humanity is going to survive into the future, we need to better understand how complex properties, somehow, emerge from simple rules," says Levin. Much of science is focused on "controlling the low-level rules. We also need to understand the high-level rules," he says. "If you wanted an anthill with two chimneys instead of one, how do you modify the ants? We'd have no idea."

"I think it's an absolute necessity for society going forward to get a better handle on systems where the outcome is very complex," Levin says. "A first step towards doing that is to explore: how do living systems decide what an overall behavior should be and how do we manipulate the pieces to get the behaviors we want?"

In other words, "this study is a direct contribution to getting a handle on what people are afraid of, which is unintended consequences," Levin says--whether in the rapid arrival of self-driving cars, changing gene drives to wipe out whole lineages of viruses, or the many other complex and autonomous systems that will increasingly shape the human experience.

"There's all of this innate creativity in life," says UVM's Josh Bongard. "We want to understand that more deeply--and how we can direct and push it toward new forms."
