Spinogenix has been awarded a research grant from the U.S. Department of Defense (DOD) to further test its lead compound as a potential treatment of amyotrophic lateral sclerosis (ALS), the company announced.

We are pleased that the DoD has recognized the potential of our novel drug candidate to change the course of disease progression in ALS, Stella Sarraf, PhD, founding CEO at Spinogenix, said in a press release. The grants amount and its duration were not disclosed in the release.

ALS is characterized by the progressive loss of motor neurons, or the nerve cells involved in the control of voluntary movement. Although some ALS treatments can slow nerve cell degeneration, they are not disease modifying and provide only a modest survival benefit. Spinogenix also noted in its release that not all patients tolerate these treatments well.

Spinogenixslead therapy candidate is a small, orally bioavailable, molecule designed to induce an increase in synapses the point of contact between two nerve cells that allows them to communicate. Its goal is to restore these neuronal connections and reverse patients decline in cognition and motor function, two faculties often affected in neurodegenerative diseases.

Spinogenix reports that the compounds mechanism is well understood, and believed to work across all the diseases where synapse loss occurs, regardless of the underlying disease mechanism.

With this grant from the DODs Congressionally Directed Medical Research Programs, Spinogenix aims to study the potential therapy using induced pluripotent stem cells (iPSCs) derived from both ALS patients and healthy controls.

iPSCs are stem cells generated from mature cells derived from the skin or blood that can give rise to different cell types, including nerve cells, depending on the particular chemical cues they are given. When these cells are derived directly from patients, they generate cellular models that mimic the diseases genetic and clinical diversity.

Additional experiments will also be conducted in ALS animal models.

Under the grant, Spinogenix will collaborate with researchers Rita Sattler, PhD, at the Barrow Neurological Institute, and Justin Ichida, PhD, at the Keck School of Medicine of the University of South Carolina.

Spinogenixs novel approach has the potential to demonstrate that replacing lost synapses may result in drugs that can provide a meaningful benefit for patients with ALS, said Merit Cudkowicz, MD, director of the Sean M. Healey and AMG Center for ALS at Mass General Hospital.

Skin Stem Cells Comments Off on Exosome Therapeutic Market Overview By Size, Share, Trends, Growth Factors and Leading Players With Detailed Analysis of Industry Structure – KSU |… | January 9th, 2021

I'm not the biggest fan of New Year's resolutions, but I like to think that as we enter the top of January there is no better time to try something new.

Growth of the global market is attributed to factors such as the growing prevalence of obesity, diabetes, cancer, and other chronic diseases which leads to organ damage, a strong product regulatory scenario, and strong investment in research and development activities by key market players including Abbott Laboratories, Cryolife Inc., Bristol-Myers Squibb, Novartis Ag, F. Hoffmann-La Roche Ltd., Medtronic, Arthrex Inc., Depuy Synthes (Johnson & Johnson), and Allosource.

Although various factors facilitate the global market for organ and tissue transplantation and alternatives, certain parameters such as challenges in HLA sequencing and gaps in supply and demand can constrain market growth. For instance, although there is an increasing need for organ transplants, the shortage of organs worldwide limits the number of transplant procedures performed, and in turn, creates an impact on transplant diagnostics procedures. An increasing number of candidates on the waiting list for organ transplant procedures worldwide further widens this gap of availability and requirement of organs for transplant purposes.

Successful organ and tissue transplantation began to arrive in the mid-1970s when tissue typing coupled with the use of cyclosporine provided more successful graft and patient survival. Today, patient and graft survival for kidney transplants is higher than 90% for the first year post-transplant, and often the success rate is 80% to 90% for five years post-transplant, with some recipients living more than 20 years after their transplant.

Continuing developments in organ procurement, organ preservation, tissue typing, and immunosuppressant use have bolstered successful transplantation surgical techniques. Evolving posttransplant drug and testing regimens have added to the success rate with close post-transplant monitoring and immunosuppressant dosage review.

Skin Stem Cells Comments Off on Global Organ and Tissue Transplantation and Alternatives Market to 2024 – Impact Analysis of COVID-19 – Yahoo Finance | January 9th, 2021

Ah, pregnancy. That wild, magical time when youre growing new life and all that, but also experiencing crazy symptoms of bodily change daily. Today, a fire-breathing dragon might be sending shooting flames of heartburn up your oesophagus, while tomorrow, pigmentation-induced maps of lost lands might appear overnight on your body. Its a game of Russian roulette because you never know what youre going to get.

A womans skin and hair are two of the areas that undergo massive change, and just like with other pregnancy side effects, you cant predict which ones youll get. Women whove never suffered a zit in their life can suddenly sprout a crop of hormonal acne, or find their bright, taut complexion is now droopy and sallow, while others are plagued by melasma and other pigmentation issues. These problems may be cosmetic, but they can be as unsettling and debilitating for women as other medical side effects, at a time when their bodies and minds are going through profound changes.

Dr Lara Devgan, a celebrity plastic surgeon in New York, shares the most common skin and hair concerns she sees in pregnant women and shares her top tips to safely alleviate them, using a combination of products and in-clinic procedures. Devgan also has six children of her own and is no stranger to post-baby skin and hair issues herself, so this advice is definitely doctor-vetted.

Hyperpigmentation and melasma are the most common skin complaints during and after pregnancy. An even skin tone is a marker of beauty, so hyperpigmentation can be quite unsettling. Melasma is so life-altering that it is sometimes referred to as the mask of pregnancy. Hyperpigmentation is multifactorialdue to genetics, hormonal fluctuations, environmental exposures like sun and heat, stress, trauma, and other unknown phenomena. The best way to address hyperpigmentation is multifactorial as well: topical skincare products like Vitamin C and E are safe to use during pregnancy and breastfeeding. After that, Devgan suggests adding a retinol or bakuchiol serum and considering microinfusion, micro-needling, peels, and lasers for more aggressive treatment of hyperpigmentation.

Pregnancy can often be associated with dullness, dryness, and loss of skin elasticity and lustre. Devgan recommends a hyaluronic serum for increased skin hydration during pregnancy. Postpartum, she suggests laser resurfacing; Its an amazing technique for rejuvenation of the skin, offering a complete skin reset to improve lustre, texture, discolouration and fine lines. She recommends the Erbium laser for a thorough resurfacing of the skins surface; it also has a much lower risk of post-laser hyperpigmentation in Indian skin tones.

Getting wrinkles and pimples at the same time can seem like the worst of both worlds for pregnant and nursing women. The best way to address acne during pregnancy is spot treatment with benzoyl peroxide and salicylic acid-based treatments. It is also important to think about daily routines and habits like cleansing the face, regularly changing pillowcases, and sterilising cell phone screens, says Devgan. Once nursing is complete, in-office treatments can also help. Intense Pulsed Light (IPL) can be used to selectively target the bacteria that causes acne. Prescription oral medications may also help. Often, when hormones normalise after delivery, the skin also tends more toward its baseline homeostasis, says Devgan.

Hair loss is one of the most distressing things to happen in the postpartum period. Because of a rapid decrease in progesterone as well as fluctuations in oestrogen levels, the thick, beautiful hair of pregnancy begins to shed shortly after delivery. Hair loss is a complex and multifactorial issue, with many solutions, says Devgan. A supplement rich in biotin, folate, and vitamin B derivatives can help boost growth by restoring the deficient cellular building blocks needed for hair growth. Topical sprays and foams such as minoxidil (Rogaine) can also help the survivalof hair follicles. Devgan also frequently performs Platelet Rich Plasma (PRP) injections into the scalp to help boost growth factors and stem cells needed for hair growth.

Skin Stem Cells Comments Off on A celebrity dermat’s tips for new moms on how to deal with postpartum hair and skin issues – VOGUE India | January 9th, 2021

There's no better time than a national lockdown to test out the coolest new skincare/makeup/hair trends and snazzy innovations in beauty tech from the comfort of your own home. That said, there's nothing more frustrating than spending upwards of 100 on a snazzy new hair treatment or at-home facial system, only to find out it doesn't *actually* work.

Enter GLAMOUR Tries: the weekly Instagram series which sees GLAMOUR editors do all of the time-consuming (and expensive) work for you.

We've been busy trying out all of the (sometimes) wacky but always wonderful beauty crazes to take the internet by storm - from the hair pods seen backstage at Victoria Beckham during fashion week to Sarah Chapman's 138 Meso-Melt Infusion at-home facial and Ciate's nail stickers which promise an Instagram-ready manicure in minutes. These are the products that every veteran beauty sleuth is talking about - but that you want to do a bit of research into before buying.

Thanks to GLAMOUR Tries, you won't need to waste your hard-earned pennies on testing these innovations yourself. We're getting in their first, giving you the lowdown and making sure you invest in products that genuinely work. Like what you see? You can shop all of the products seen on GLAMOUR tries, with the click of a button, down below. Don't say we don't treat you.

This week, our Social Media Assistant Luca Wetherby-Matthews tried FOREO's UFO 2 LED Power Mask. Described as "the future of your weekly masking ritual", it's designed to supercharge your pampering sessions by offering you a range of treatments in one device to tackle your main skin concerns.

Condensing a 20-minute session into 90 seconds, it works in combination with the specially invented UFO-activated masks and each treatment incorporates a carefully chosen combination of temperature and pulsation intensity for maximum effect and soothing facial massage. It switches between thermotherapy (warm) to soften the skin to cryotherapy (cold) to lift and firm. That's the "Power Mask" part.

The light therapy part? The effects of the aforementioned treatments are boosted with a choice of eight light settings from antibacterial blue light to sunburn-soothing yellow LED. Of course, LED face masks are big news right now, thanks to their ability to reduce breakouts, pigmentation, rosacea symptoms, psoriasis and other side-effects of inflammation. If you don't suffer from the above complaints, LED light therapy can simply help to improve the appearance of your skin. It's a great time to invest.

So, how did Luca get on? "It might seem a bit overwhelming, but something really impressive is that you can connect this to your FOREO app, and the app will guide you through your treatment based on the mask you use with it," Luca said. "It'll choose your LED settings and every other setting, doing all the hard work for you."

"My skin feels so good, and it was actually much more of a relaxing experience than I thought it was going to be. Just because it's such a quick treatment, I didn't know what to expect. But things like the cryotherapy just felt insane! So refreshing, really professional and the pulsations really relaxed my muscles. I love that you can just follow along on the app, which is so intuitive."

Stem cells are biological cells which have the ability to distinguish into specialized cells, which are capable of cell division through mitosis. Amniotic fluid stem cells are a collective mixture of stem cells obtained from amniotic tissues and fluid. Amniotic fluid is clear, slightly yellowish liquid which surrounds the fetus during pregnancy and is discarded as medical waste during caesarean section deliveries. Amniotic fluid is a source of valuable biological material which includes stem cells which can be potentially used in cell therapy and regenerative therapies. Amniotic fluid stem cells can be developed into a different type of tissues such as cartilage, skin, cardiac nerves, bone, and muscles. Amniotic fluid stem cells are able to find the damaged joint caused by rheumatoid arthritis and differentiate tissues which are damaged. Medical conditions where no drug is able to lessen the symptoms and begin the healing process are the major target for amniotic fluid stem cell therapy. Amniotic fluid stem cells therapy is a solution to those patients who do not want to undergo surgery. Amniotic fluid has a high concentration of stem cells, cytokines, proteins and other important components. Amniotic fluid stem cell therapy is safe and effective treatment which contain growth factor helps to stimulate tissue growth, naturally reduce inflammation.

2021: What are the best self-care products to buy in the new year? - The Jerusalem Post

Skin Stem Cells Comments Off on 2021: What are the best self-care products to buy in the new year? – The Jerusalem Post | January 3rd, 2021

More than 25 years ago, it was a patient with a port-wine stain who inspired Alster to learn more about the then-fledgling world of lasers. Alster accepted a fellowship in Boston, where her patient traveled to receive treatments. So in essence, I changed her life because I significantly lightened the birthmark to the point where she didn't need to cover it, says Alster. And she changed my life because I wouldn't have looked into lasers if it wasn't for her... I ended up opening up my own center in Washington, D.C. in 1990. And at that time it was the only freestanding laser center in the world.

Lasers and Scars

Lasers can treat many types of scars, including surgical scars, acne scars, and scars from injuries. They penetrate the epidermis to stimulate new, healthy skin cell growth. The most common lasers used in scar removal are ablative fractional carbon dioxide lasers, Nd:YAG, nonablative fractional lasers, and pulsed dye lasers.

Lasers and Hair Removal

Laser hair removal is a medical procedure that uses a concentrated beam of light to remove unwanted hair. The laser emits a light that is absorbed by the pigment (melanin) in the hair. The light energy is converted to heat, which then damages the hair follicles that produce hairs. This damage inhibits or delays future hair growth. With repeated treatments, laser hair removal can permanently reduce unwanted hair. While all hairs dont fall out immediately, they will shed within days to weeks of treatment.

But lasers arent only used for hair reduction. Low-Level Laser Therapy (LLLT) is a relatively new treatment that uses low-power lasers to stimulate hair growth. Its hypothesized that LLLT stimulates stem cells in the hair follicle and shifts the follicles in the anagen (growth) stage of the hair cycle.

How is LED different from lasers?

Commonly confused with lasers, light-emitting diodes (LED) can reduce fine lines, increase collagen production, and smooth skin by using varying color wavelengths of visible LED light. Lasers, on the other hand, often use a single wavelength, and the beam is ideal for stimulating changes that only respond to very specific wavelengths (hair removal, dark spot removal, etc.).

Can you combine lasers with other in-office treatments in the same session?

Short answer: Yes! Depending on the laser you and your dermatologist choose, you can get filler or Botox in the same treatment. Some experts will specifically recommend injectables with Fraxel within the same appointment since its considered safe and delivers a rather dramatic final result. Alster often combines non-ablative laser treatments with microneedling to amplify the effects.

Can you be too young for lasers?

When deciding whether or not to try a laser, your age shouldnt be a major deciding factor. It's more of a matter of the problem you want to fix, not how old you are. Many young people have rosacea, acne, sun spots, and sun damage all of which are treatable with lasers. Still, less-intensive therapies, such as chemical peels, are likely enough to repair young, relatively healthy skin (and are often less expensive).

Is it safe to laser your skin at home?

There are various options for at-home laser treatments that you can use safely. Typically, at-home devices have significantly lower power than those used in a medical setting, in order to reduce risks. Many lasers for wrinkles or acne are simply LED light products, like the Dr. Dennis Gross Skincare DRx SpectraLite mask. There are, however, a few at-home non-ablative fractional lasers available, like the Tria SmoothBeauty Laser.

Michelles Current Favorites

While everyones skin is different and your personal dermatologist knows whats best for you Michelle says she slathered her face with Aquaphor following a Fraxel treatment. You really do need to keep your skin moist [afterward], she says. And then it's all about sunscreen, sunscreen, sunscreen. Right now, Michelle is into Dr. Loretta Urban Antioxidant Sunscreen SPF 40, which has a slight tint.

Jennys Current Favorites

Like Michelle, Jenny used Aquaphor after getting Fraxel. She also used CeraVe Moisturizing Cream post-treatment to help speed up healing. And in order to cover up the sandpaper-like texture and small, dark dots that often arise after getting Fraxel, Jenny used Oxygenetix Oxygenating Foundation. A lot of dermatologists and plastic surgeons recommend it for people to use this when they're healing, she says. It's thicker than what I would normally use for foundation, but it gave a really seamless finish [and] got me through that week or two after [treatment].

Like many in-office treatments, lasers often come with some downtime. But good things come to those who wait: Lasers can have a huge impact on the look and health of your skin.

Vaccines at warp speed

Only one breakthrough truly mattered this year: the creation of a COVID-19 shot. The previous record for the fastest vaccine development, for mumps, was four years. But on Dec. 8 11 months after research began a 90-year-old British grandmother became the first person in the world to receive Pfizer's new COVID vaccine outside of a clinical study. Like Moderna's new shot, which was approved in the U.S. last week, the two-dose vaccine is about 95 percent effective and uses an entirely new type of technology. In traditional vaccines, a patient is injected with dead viral material, which triggers the body to produce antibodies. Pfizer's and Moderna's shot use a synthetic version of coronavirus genetic material that leads human cells to produce copies of the virus' outer spike proteins. Those proteins spark an immune defense. Pfizer and Moderna together hope to deliver enough doses for 20 million people by Dec. 31. "The light at the end of the tunnel is getting a little brighter," says infectious-disease expert Dr. William Schaffner.

Solving a protein puzzle

An artificial intelligence program appears to have solved one of the biggest mysteries in biology. The "protein-folding problem" is important because most biological processes such as how insulin controls blood-sugar levels or how antibodies fight coronaviruses are driven by proteins. How the strings of amino acids that make up a protein twist and fold into a 3D shape determines its function. Trying to establish how proteins get their origami-like structure can take years of lab work. But AlphaFold, an artificial intelligence program developed by the Google-owned DeepMind lab, can do it in a matter of hours with a remarkable level of accuracy. Bioinformatics professor Janet Thornton says protein-folding was "a problem that I was beginning to think would not get solved in my lifetime."

Building living 'bots

American scientists have created the world's first living robots. The millimeter-wide "xenobots" were formed by scraping live stem cells from frog embryos and leaving them to incubate. The resulting skin and heart cells were then reshaped and combined into "body forms" designed by a supercomputer to complete certain tasks walking, for example, or swimming. The pulsing heart cells serve as a miniature engine that powers xenobots until their energy reserves run out after about 10 days at present. Study co-leader Michael Levin says these "living, programmable organisms" might one day carry out tasks such as removing plaque from artery walls.

Signs of life on Venus?

Scientists have found hints that life might exist on Venus a notoriously inhospitable planet where surface temperatures hit 860 degrees Fahrenheit. Using powerful telescopes, researchers detected traces of the gas phosphine in the Venusian atmosphere. On Earth, that gas is produced by human industry and by microbial organisms that live in oxygen-free environments. Phosphine is quick to react and disappear, so something must be replenishing its supply on Venus. Researchers say it's not implausible that single-celled life might survive in the Venusian atmosphere, floating in a region where liquid water exists. Study co-author Sara Seager says the only way to confirm this theory is by "actually going to Venus."

The big scientific breakthroughs of 2020 - The Week

Skin Stem Cells Comments Off on The big scientific breakthroughs of 2020 – The Week | December 30th, 2020

A U.S. study has shown for the first time that enhancing signals from the nociceptive nervous system could provide new approaches to improve the collection of hematopoietic stem cells (HSCs) for treating cancers of the blood and bone marrow, the authors reported in the December 23, 2020, edition of Nature.

The findings may help cancer treatments, as "in a meaningful fraction of leukemia, multiple myeloma and lymphoma patients, particularly those who have received anticancer treatment, the HSC mobilization yield can be insufficient," said study leader Paul Frenette.

"Therefore, more efficient HSC mobilization methods would allow the harvest of sufficient HSCs for life-saving transplantation," said Frenette, a professor and director of the Ruth L. and David S. Gottesman Institute for Stem Cell and Regenerative Medicine Research at Albert Einstein College of Medicine in New York.

HSCs characteristically migrate to different hematopoietic sites during embryonic development and continue to be released from the adult bone marrow.

Most hematopoiesis occurs in the bone marrow, where different types of blood cells are derived from limited numbers of HSCs, which are multipotent and capable of extensive renewal.

The HSC migratory properties have facilitated their collection from the blood and transplantation as regenerative cancer treatment, although the mechanisms by which HSCs migrate out of the bone marrow remain largely unknown.

In tissues exposed to the external environment, such as the skin, lung and gut, nociceptors enable the rapid detection of external insults, including pain, cold or heat, in order to avoid organ damage.

Nociceptor sensory neurons detect these harmful stimuli and can regulate the immune response to them by releasing neurotransmitters and other regulatory molecules.

However, other than for pain perception, the role of nociceptors in a deep tissue, such as the bone marrow, is poorly understood.

In bone marrow, HSCs are found in specialized microenvironments or niches, which are complex regulatory environments influenced by multiple cellular constituents, including nerves.

Although sympathetic nerves are known to regulate the HSC niche, the role of nociceptive neurons in the bone marrow in this regard remains unclear.

"We have previously shown that nerves from the sympathetic nervous system promoted HSC mobilization in bone marrow, so we were curious to see whether nociceptive neurons might also be involved," Frenette told BioWorld Science.

In their new Nature study, the Frenette and his team showed that nociceptive neurons are required for HSC mobilization and that they interact with sympathetic nerves to maintain HSCs in the bone marrow.

Notably, nociceptor neurons were demonstrated to drive granulocyte colony-stimulating factor (G-CSF)-induced HSC mobilization via secretion of calcitonin gene-related peptide (CGRP).

"Our findings may lead to more efficient mobilization methods in [blood and bone marrow cancer] patients in whom existing methods are insufficient," Frenette said.

For example, "we have shown that the CGRP pathway synergizes with G-CSF and plerixafor [(Mozobil, Genzyme), an immunostimulant used to mobilize HSCs into the bloodstream in cancer patients]." Unlike sympathetic nerves, which regulate HSCs indirectly via the bone marrow niche, CGRP was shown to act directly on HSCs via receptor activity modifying protein 1 (RAMP1) and the calcitonin receptor-like receptor to promote HSC egress via Galphas/adenyl cyclase/cAMP signaling pathway activation.

This research identifies potential treatment targets for boosting HSC mobilization, since "we have shown that increasing the downstream signaling of the CGRP receptor RAMP1, by increasing cyclic AMP can enhance HSC mobilization," said Frenette.

Importantly, the Einstein researchers then showed that ingestion of food containing capsaicin, a natural component of chili peppers that can trigger the activation of nociceptive neurons, significantly enhanced HSC mobilization in mice.

"Capsaicin tablets are currently sold over-the-counter to 'help support cardiovascular and digestive function' at higher doses than that predicted by our studies in mice for stimulating HSC mobilization in humans," said Frenette.

"These relatively low concentrations of capsaicin have biological effects without seemingly causing obvious pain," he said.

Collectively, these findings therefore suggest that targeting the nociceptive nervous system could represent a novel strategy by which to improve the yield of HSCs for stem cell-based therapies. (Gao, X. et al. Nature 2020, Advanced publication).

Marco Kaltofen was 11 when he noticed his first white hairs. As his hair grew whiter, his middle-school friends started calling him the professor. By his mid-30s, it was completely white, as it had been for three of his grandparents. His parents went white in their 40s, so I had no chance of avoiding this, Kaltofen says.

Now 61, he is a civil engineer who lives in Boston. He wears his white hair in a ponytail. White hair is part of my identity, and I am completely at peace with it, he says.

Then there is Joe Rees, 75, a retired customs attache who lives in Washington. He is balding, but the hair that remains on the sides and in the back is the same dark brown it always has been. He jokingly attributes this to clean living and a pure heart, although, like Kaltofen, it probably is genetic. His mothers black hair didnt start to go gray until she was in her 70s, and was 50/50 when she died at 88, he says.

Still, Id rather be gray than bald, he says. That way, I wouldnt have to worry about wearing a hat all the time.

To be sure, Rees and Kaltofen are exceptions, since most people start graying in their 50s and 60s. Nevertheless, their experiences are among the many mysteries of gray, white or silver-looking hair that scientists are exploring to learn more about aging. They want to know why some people turn gray early and others late or not at all and what this might signal about their health. They also want to understand the factors that hasten graying, and even whether gray hair is reversible which could be a boon to those allergic to hair dye, or who hate spending money to keep the gray away.

Most important, studying gray hair could point to new approaches in promoting healthier aging, says Candace Kerr, health scientist administrator in the National Institute on Agings Division of Aging Biology.

While graying is one of the markers of aging aging is the ultimate risk factor for why hair goes gray it highlights the need for better understanding of the mechanisms that drive aging and age-related diseases, she says. To be able to target these pathways will be critically important for our aging population to live longer and happier lives.

Hair that looks gray, white or silver actually is colorless. Hair color comes from melanin, a pigment produced by cells in the hair follicles. Over time, these cells suffer damage and become depleted, losing their ability to make melanin. This results in new hair without pigment meaning, no color.

People use gray, white and silver interchangeably to describe hair that is turning or has turned. Its appearance whether it looks, gray, white or silver depends on how much natural color, or pigment, remains, experts say. Hair that has lost all its color typically appears white.

Studies have identified a number of factors that also may speed up gray hair, including smoking, diet, stress and genetics.

Our hair color depends on a set of specialized stem cells called melanocyte stem cells, and every time a new hair grows, these melanocyte stem cells have to divide in two and make a new melanocyte, [or] pigment cells, explains Melissa Harris, assistant professor of biology at the University of Alabama at Birmingham. These pigment cells stay in the base of your hair and their job is to produce pigment. These melanocytes reach out skinny arms, called dendritic processes, that shuttle the pigment to the hair shaft as it grows. So if all your melanocyte stem cells disappear, so do your melanocytes and so does your hair pigment. Thus gray hair.

Because stem cells directly influence hair color, studying gray hair can provide insights about why stem cells age and ultimately fail, offering important clues about the workings of other stem cells in the body for example, those found in muscles, bones and organs. In turn, these ultimately could point to whether gray hair could be a marker for disease, or the opposite, a longer life. Previous studies have not shown a relationship between life span and gray hair, including whether late onset of gray hair predicts longevity. Some research, however, indicates that gray or white hair can be a sign of early heart disease, regardless of age.

In some people, gray hair could potentially serve as indication of their health for instance when caused by stress, or a signal for those who may be developing cardiovascular disease, Kerr says. We still need to learn more about whether and, if so, how late onset of gray hair can signal better health and longevity in some people under certain circumstances, as well as whether early graying means stem cells might be aging.

There are many different stem cells in our body which may or may not age by different means, she says. How stem cells mark aging overall and how they could interact to promote aging is an important question.

This is why scientists who study gray hair regard it as a valuable research tool.

As gray hair researchers, we often have to defend why we study a cosmetic characteristic, rather than a life-threatening disease, Harris says. But what is very cool about gray hair from a scientific point of view is that we can see it with our own eyes, meaning we dont have to take invasive biopsies, and it doesnt kill you. We have asked a lot of important and interesting questions about stem cells by studying gray hair in mice. And, we are constantly on the lookout for gray-haired mice so we can use our scientific skills to find out what makes them gray.

A 2018 mouse study by Team Hair-Us (Harris nickname for her lab colleagues) found a connection between MITF (microphthalmia), a transcription factor (a protein involved in gene expression) important in managing pigment production, and the innate immune system, suggesting that some peoples hair may turn gray in response to serious illness or chronic stress. They discovered a relationship between genes involved in hair color and those that trigger an immune response to a viral infection, suggesting this interaction could increase the chances of developing gray hair.

MITF, in a sense, shields melanocyte stem cells from our own immune system, she says. Normally our immune system protects our bodies from infection. But for melanocyte stem cells, too much immune response is bad for their health, and this leads to their loss and to gray hair. Why melanocyte stem cells are so sensitive to our own natural means for protection, we still dont know.

Im very curious to see whether we see an uptick in individuals with gray hair due to coronavirus infection, she says. Unfortunately, we probably wont know because gray hair is rarely documented clinically, unless it is very extreme.

Scientists still dont know why some people turn gray early, late, or not at all, although they suspect genes, nutrients and possibly the immune system play a role in depleting melanocyte stem cells.

There is still much to learn about what regulates these stem cells and what may contribute to their loss, says Ya-Chieh Hsu, associate professor of stem cell and regenerative biology at Harvard University and principal faculty member of the Harvard Stem Cell Institute.

Among other things, Hsu studies the effect of stress on graying. Most of us are familiar with those before-and-after photographs of U.S. presidents most recently Barack Obama showing a striking increase in gray hair during their terms, even in relatively young presidents. Its known as the Marie Antoinette Syndrome, after the 18th-century French queen whose hair allegedly turned white overnight before she went to the guillotine and her death at age 38 during the French Revolution.

With the aging process, we gradually lose melanocyte stem cells one-by-one over a very long period of time, Hsu says. What we found in our research was that the stress can accelerate that process.

Hsu and her colleagues found that stress stimulates the same nerves that trigger the fight-or-flight response, which in turn causes permanent damage to the pigment-producing cells in hair follicles. The fight or flight response is thought to be a good thing in stressful situations because it can drive us and other organisms to respond to danger rapidly, Hsu says. This activation causes a spike in the neurotransmitter norepinephrine. Norepinephrine raises our heartbeat and allows us to react quickly to danger without having to think about it.

But norepinephrine also tells melanocyte stem cells to pump up their activity and proliferate, and too much norepinephrine, in this case triggered by stress, causes the melanocyte stem cells to burst into so much activity it leads to rapid depletion of the stem cell reservoir, she says. If all the stem cells are depleted, no more pigment-producing cells can be produced anymore, and the hair turns gray.

Other stress hormones, ACTH (adrenocorticotropic hormone) for example, can cause melanocyte stem cells to migrate away from the hair follicle before they can produce the melanocytes needed for hair and skin color, according to research. Such hormones are known to increase in the body after stress, and may have the potential to promote the loss of these cells, regardless of age, says study author Mayumi Ito, associate professor in the departments of cell biology and dermatology at the New York University Grossman School of Medicine.

Hsu believes the connection between stress and hair color could reveal additional information about how stress affects other biological processes. How stress affects our tissues is still poorly understood, and one of the powerful aspects about the melanocyte is that it provides a visible and highly trackable system to study stress, she says.

Ito also found that certain cell signaling proteins called endothelins (substances known to constrict blood vessels and raise blood pressure) bind to melanocyte stem cells and, in doing so, keep them healthy. Interrupting the process causes cell loss and early graying in mice. They are studying whether the same happens in human hair follicles, hoping to find ways to preserve or regenerate the key stem cells that give hair its color.

All of this raises the intriguing possibility that scientists could discover ways to prevent or reverse gray hair.

Team Hair-Us recently published a paper describing a topical drug combination that increased melanocyte stem cells in gray mice, ridding them of their gray and restoring their original fur color perhaps for good. Because the treatment originally developed to regrow hair replenished pigment-producing stem cells, the effects could be long-lasting, Harris says.

We didnt keep the mice forever so we dont know, says Harris, who plans more studies. This has made us very interested in whether gray hair really is permanent, and if we can do something about it. We really want to know and so does everyone else we talk to is whether and when we can bring this to humans.

Getting to the root of why hair goes gray - messenger-inquirer

Skin Stem Cells Comments Off on Getting to the root of why hair goes gray – messenger-inquirer | December 26th, 2020

Chafing occurs when the skin rubs against something, such as clothing, for a prolonged period. The friction can cause a painful rash that typically resolves when the chafing stops.

A person can experience chafing on any part of the body that encounters friction. The resulting rash is often minor, but there are some possible complications.

In this article, we look at what causes chafing rash and how to treat it. We also look at how a person can prevent chafing from occurring.

A chafing rash occurs anywhere on the body where the skin is rubbing against clothing or other skin.

Mild chafing rashes tend not to be too painful, but more serious rashes could bleed, crust, or blister. Chafing can occur anywhere where there is friction, but some areas of the body are more prone to chafing than others.

Areas where chafing is most likely to happen are generally moist or generate friction. They include the:

The direct cause of chafing is the skin is rubbing against something for a prolonged period. This could happen, for instance, when someone is walking and their inner thighs are rubbing together.

Chafing is more likely to occur in particular areas of the body, and it tends to happen during physical activity, such as running.

Others causes of chafing include:

Additionally, an infant or toddler wearing a diaper may experience chafing due to the added moisture and movement in the area.

Learn more about the types of diaper rash here.

Chafing causes a burning or stinging rash to occur where the skin is rubbing against something. The rash will not spread to other areas.

Possible complications of chafing rashes include:

Bacteria could enter through the broken or damaged skin around a chafing rash and cause an infection. For that reason, a person should make sure that they take care of the rash and keep it clean. The Centers for Disease Control and Prevention (CDC) list several symptoms of a skin infection, which include:

Chafing rashes will typically clear up within a few days if a person stops the activity causing the chafing or takes action to prevent further chafing.

Excessive moisture and skin friction may lead to skin breakdown. Patting the skin dry to remove excess moisture may prevent complications of chafing rash.

A person may also wish to consider applying shea butter lotion to the rash. A 2012 study found that shea butter has anti-inflammatory properties, which could make it a good option for people who want to soothe a chafing rash with cream.

For pain, a person can try applying aloe vera to the skin, as it may soothe sore skin and help prevent infections.

People have also traditionally used a range of other plant oils, including olive oil and coconut oil, to treat skin-related issues. Further research is necessary to confirm the benefits of each of these oils.

Unless the skin becomes infected, doctors do not have a standard way of treating chafing rash. A person should avoid the activity that caused the chafing. If they cannot avoid the activity, they should take steps to prevent further chafing from occurring.

If a person needs treatment, a doctor may prescribe or recommend a corticosteroid cream or ointment to help reduce the inflammation resulting from the rash.

It is not always possible to prevent chafing from occurring, but a person can take certain steps to reduce the risk.

According to the American Academy of Dermatology Association, these steps include:

Other steps a person can take to help prevent chafing include:

Additionally, the findings of an older study suggest that a person can apply petroleum jelly to the skin to minimize friction and prevent chafing rash.

If a person develops a rash that spreads, it is likely not a chafing rash. A person should consider seeing their doctor if the rash does not go away within a few days of home treatment.

A person should also talk to their doctor if they suspect that their rash has become infected. A doctor can examine the rash and determine whether additional treatment is necessary.

A chafing rash is often a mild rash that occurs when skin rubs against clothing or other areas of skin. Many cases are mild and will go away when a person stops the activity causing the chafing.

A possible complication of chafing rash is a skin infection. A person should speak with their doctor if the rash is severe or they think that it has become infected.

At-home treatments for chafing rash include aloe vera and other soothing ointments. A person can take preventive steps to reduce the risk of a rash forming, such as wearing moisture-wicking clothing and applying petroleum jelly to areas prone to chafing.

What causes chafing rash? Remedies, treatment, and prevention - Medical News Today

Skin Stem Cells Comments Off on What causes chafing rash? Remedies, treatment, and prevention – Medical News Today | December 24th, 2020

Rashes can appear differently on different skin tones. For example, a heat rash on darker skin may look like a series of gray or white spots, while many medical sources describe them as red.

It is crucial for medical professionals to understand how health issues can present on the full range of skin tones. A lack of this understanding can lead to misdiagnoses.

It is generally advisable to contact a doctor about any rash that lasts longer than a week. The Skin of Color Society offer a database of dermatologists in the United States who have experience treating conditions in people of color.

In this article, we explore what rashes can look like on skin of color. We also describe the symptoms and treatments of specific issues.

The appearance of a rash varies with skin tone. On skin of color, a rash may be purple, gray, or white while medical texts often simply describe these rashes as red. Some redness may appear, but typically not very much.

This is due to melanin, a molecule that gives the skin and hair their color. Generally, the more melanin a person has in their skin, the darker their skin tone. It affects how the skin reacts to sunlight, damage, and health conditions that cause rashes.

Some doctors are unaware of how skin conditions present on darker skin. A 2018 study of four major medical textbooks found that darker skin tones were underrepresented in the imagery.

The studys authors report that while, at the time, 20.4% of the U.S. population was Black, only 4.5% of the photographs in the textbooks showed people with dark skin. They suggest that this is likely an example of racial bias in the healthcare system.

Below, we explore how various health issues can appear in skin of color.

Heat rash, sweat rash, and prickly heat are all common names for miliaria, a skin condition that occurs when the skins sweat ducts become blocked.

The symptoms of heat rash include:

On darker skin, the blisters may be gray or white.

This rash often occurs due to heat and humidity, but intense exercise, nonbreathable clothing, and medical dressings can also cause it. The condition typically improves within 12 days.

Cooling down, wearing more breathable clothing, and changing or, if recommended, removing dressings can help.

Eczema causes patches of dry, itchy skin, and the affected area may also be flaky or scaly. If the skin is very dry, it may crack or bleed.

In darker skin tones, patches of eczema may be red, pink, magenta, or darker than surrounding skin.

Eczema is also more likely to form in specific ways in people of color. For example, there is a higher chance that the rash may be papular, characterized by a series of small bumps like goosebumps.

There are several types of eczema, including:

This occurs when the skin comes into contact with an irritant, such as poison ivy, nickel, or fragrance. The skin may itch, sting, burn, or blister.

People with certain jobs have a higher risk of contact dermatitis. These jobs may involve regular contact with chemicals, food, or water. People with a higher risk may include:

Avoiding contact with the trigger, such as a specific chemical, is the best approach. A dermatologist can also describe products that can help and perform skin allergy testing to identify the trigger.

Atopic dermatitis is eczema with no clear cause. The condition often begins in childhood and may not last into adulthood. In the U.S., it appears to be more common among African Americans, Asian Americans, and Pacific Islanders than other groups.

There is no cure for atopic dermatitis, but there are ways of alleviating and preventing the rash from forming.

This typically involves using a non-irritating moisturizer regularly, after bathing or showering. It is also important to avoid fragranced products, food allergens, and irritating fabrics, such as wool. In addition, a person may need a topical corticosteroid, which a doctor can recommend or prescribe.

Psoriasis is a long-term inflammatory condition that causes thickened patches of skin. On skin of color, these patches may be red or violet and have a top layer of silver or gray scales.

In the U.S., psoriasis is more common in white people than Black people. However, in Black people, it may be more likely to cover larger areas of the body.

Psoriasis can affect the nails as well as the skin, and a significant portion of people with psoriasis also have arthritis.

There is no cure, but it is possible to manage the symptoms. Among the range of options are:

Lichen planus causes a series of bumps to form on the skin. Each bump is shiny, raised, and has a flat top. On skin of color, these bumps may be gray-brown or purple.

The most commonly affected areas are the back, neck, lower legs, ankles, and the insides of the wrists. In 20% of cases, lichen planus causes no symptoms beyond the bumps, but in others, it causes intense itching.

Lichen planus can last for months or years, and there is no known cure. Treatments that can relieve the symptoms include:

Learn more about the causes and treatments of lichen planus.

Vitiligo is a condition that causes patches of skin to lose its color, or become depigmented. If the condition affects areas with hair, the hair may turn white, too.

The condition occurs when the immune system attacks melanocytes, the cells that produce melanin. Scientists are not sure why this happens, but they believe that it could stem from an autoimmune response.

Areas commonly affected by vitiligo include:

Vitiligo can affect anyone, but it is more noticeable in people with darker skin. People with vitiligo are more likely to have a family history of autoimmune disorders.

The depigmentation often stops or slows over time. Treatments focus on reducing the spread of depigmentation and restoring color to the skin. This may include the use of medicated creams or light therapy.

Shingles is caused by the same virus as chickenpox. Anyone who has had chickenpox can develop shingles later on. One symptom that most people with shingles develop is a rash of small blisters.

The symptoms of shingles are:

Some people also experience a fever, headaches, muscle aches, stomach pain, or nausea and vomiting.

On highly pigmented skin, a shingles rash may be red, the same color as the skin, or slightly darker. The scabs may be grey.

While the rash often heals within 24 weeks, it is important for anyone with shingles symptoms to see a doctor for treatment within 23 days. This is because shingles can cause long-term complications.

The doctor can prescribe antiviral medication, which can reduce the risk of complications and shorten the healing time.

Ringworm is a fungal infection of the skin. It often causes a round or ring-shaped rash with a raised border, though the rash may be shaped differently on certain areas, such as the feet or hands.

On darker skin, the ringworm rash is often gray or brown.

Ringworm is contagious, so it is important to seek treatment right away and avoid touching the rash, even if it is itchy.

Other names for this infection include:

Treatment may involve antifungal cream or, if the rash covers a large area, oral medication.

The best approach to treatment at home depends on the cause of the rash. But there are some general strategies for preventing further irritation, such as:

It is also important to protect the skin from sun damage with a product that contains SPF 30 or higher. UV light can also worsen skin irritation for people with certain conditions.

In some cases, a rash signals a medical emergency. Seek urgent medical attention if a rash:

Anyone who may have shingles or ringworm should see a doctor promptly to prevent transmission. For shingles, a person should wait no more than 23 days.

Otherwise, it is generally a good idea to contact a doctor if any rash lasts longer than a week.

The Skin of Color Society provide a database of dermatologists in the U.S. who have experience treating conditions in people of color.

In skin of color, a rash may be red, brown, purple, or gray.

Some doctors may misdiagnose skin issues in people of color due to a lack of awareness. Skin of color is often underrepresented in medical texts.

A dermatologist who understands how rashes present in the full range of skin tones is best prepared to provide the right treatment.

Rash on black skin: Pictures, symptoms, and treatments - Medical News Today

As for your lips, we dont grow hair there because our lips are made up of a different type of cell, as theyre considered to be an extension of the gastrointestinal (GI) tract, says Mariwalla.

If having hair is so crucial to the function of our bodies, why have we been removing it for hundreds of years? Well, we have no one to blame but ourselves. We have, through communication with one another, established a globalized practice of removing hair to make women especially look very smooth and have baby-like skin; and for men to retain their body hair, says Jablonski. We tend to think, Oh, these signals are very ancient. These practices are very ancient. They're not. This is a pretty recent obsession. Jablonski estimates the practice of body hair removal started about only 500 years ago.

While modern societal standards of what femininity and masculinity are still very much linked to hairiness or lack of hairiness, weve begun to see a shift in the acceptance and normalization of body hair, thanks in part to social media, which has even helped us celebrate body hair for the first time. (Remember #freeyourpits?)

It's really wonderful when people examine those social norms and say, hold on, who started this? This is a bunch of nonsense, says Jablonski. And they realize, Hey, I can be a beautiful person inside and out without following these practices. It is tremendously liberating.

That sense of celebration seems to be more prevalent than ever before, as were living through a pandemic, which has put physical interactions between people on pause. Because of this, many of the performances we put on for others, like body hair removal, have become one-woman shows, with one-woman audiences.

So then you realize, in your heart of hearts, this is a waste of time, says Jablonski. Why should I take this time to do this thing that is socially acceptable and allows me to cleave towards a social norm? I'm doing just fine. People feel a lot of freedom now.

Of course, if you do choose to remove your body hair and thats fine too! depending on the location of the hair, there are a number of methods that will get the job done, says Mariwalla.

Shaving

For starters, theres shaving, the act of removing hair with a razor. When you shave the hair on your body (typically on the legs, underarms, and face), youre removing hair from above the top layer of skin, says Mariwalla. She recommends shaving with a cream or gel to keep the skin hydrated. The process of shaving is almost like exfoliating that top layer of skin, she says. So, it's like a two for one.

Tweezing

Tweezing, on the other hand, pulls the hair directly from the follicle. When you think about a hair follicle, it's like the little house that your hair lives in, explains Mariwalla. Any time you pull a hair from a follicle, it's always going to grow back. But its going to take longer than when you only remove it from above the skin.

Waxing and Sugaring

Waxing and sugaring use the same mechanism as tweezing but with warm substances (i.e. wax and sugar) that sit on top of the skin and around the hair to coax it out of the follicle. Its a process that is trying to warm the skin, so that the hair follicle opens up a little bit and the wax solidifies around the hair, says Mariwalla. When you remove the wax you basically rip the hair out of the follicle as you're doing it.

Depilatory Cream

There are also depilatory creams. Instead of grabbing onto the hair and pulling it, you're putting on a chemical that's dissolving the hair at the root, explains Mariwalla. So then you basically then just wipe it away.

Covid-19 sucked most of the oxygen out of science this year. But we still had brilliant wins.

The pandemic couldnt bring rockets or humans down: multiple missions blasted off to the red planet in the summer of Mars. Two astronauts launched to the International Space Stationand made it safely backin a game-changer for commercial space travel. NASA released dozens of findings on how space travel changes our bodies, paving the way to keep us healthy in orbitor one day, on Mars and beyond.

Back on Earth, scientists scoured mud ponds and fished out a teeny-tiny CRISPR enzyme that packs a massive punch for genome editing. AI and neuroscience became even more entwinedsometimes literally. Biological neurons got hooked up to two silicon-based artificial neurons, across multiple countries, into a fully-functional biohybrid neural network. Others tapped dopaminethe main messenger for the brains reward systemto unite electricity and chemical computing into a semi-living computer. While still largely a curiosity, these studies take brain-inspired computers to another level by seamlessly incorporating living neurons into AI hardware. Now imagine similar circuits inside the brainNeuralink sure is.

More abstractly, biological and artificial brains further fed into each other in our understandingand craftingof intelligence. This year, scientists found mini-computers in the input tree-like branches of neurons. Like entire neural networks, these cables were capable of performing complex logical calculations, suggesting our brain cells are far brainier than we previously thoughtsomething AI can learn from. On the flip side, a hotshot algorithm inspired by the brain called reinforcement learning pushed neuroscientists to re-examine how we respond to feedback as we learn. AI also helped build the most dynamic brain atlas to date, a living map that can continuously incorporate new data and capture individual differences.

As we leave 2020 behind, two main themes percolate in my mind, not just for what theyve accomplished, but as indicators of what lies ahead. These are the trends Ill be keeping my eyes on in the coming year.

Why we age is extremely complex. So are methods that try to prevent age-related diseases, or slow the aging process itself. This nth-dimensional complexity almost dictates that longevity research needs to self-segregate into lanes.

Take probing the biological mechanisms that drive aging. For example, our cells energy factory spews out bullet-like molecules that damage the cell. The genome becomes unstable. Cells turn zombie-like. Working stem cells vanish. Tissue regeneration suffers. Scientists often spend entire careers understanding one facet of a single hallmark of aging, or hunting for age-related genes. The lucky ones come up with ways to combat that one foefor example, senolytics, a family of drugs that wipe out zombie cells to protect against age-related diseases.

But aging hallmarks dont rear their heads in isolation. They work together. An increasing trend is to unveil the how of their interactions workcrosstalk, in science-speakwith hopes of multiple birds with one stone.

This year, longevity researchers crossed lanes.

One study, for example, took a stem cell playbook to rejuvenate eyesight in aged mice with vision loss. They focused on a prominent aging hallmark: epigenetics. Our DNA is dotted with thousands of chemical marks. As we age, these marks accumulate. Using gene therapy, the team introduced three superstar genes into the eyes of aged mice to revert those marks and reprogram cells to a younger state. Youve probably heard of those genes: theyre three of the four factors used to revert adult skin cells into a stem-cell-like state, or iPSCs (induced pluripotent stem cells). Resetting the epigenetic clock was so powerful it improved visual acuity in old mice, and the team has now licensed the tech to Life Biosciences in Boston to further develop for humans.

Another study combined three main puzzle pieces in agingzombie cells, inflammation, and malfunctioning mitochondriainto a full picture, with the surprise ending that senolytics has multiple anti-aging powers in cells. Talk about killing two birds with one stone. Finally, one team (which I was a part of) combined two promising approaches for brain rejuvenationexercise and young bloodto begin pushing the limits of reigniting faltering memory and cognition due to aging.

Longevity research has long been fragmented, but its starting to coalesce into a multidisciplinary field. These crossovers are just the start of a rising trajectory to combat the multi-headed Hydra thats aging. More will come.

If youre looking for a sign that AI is leaving the digital realm of Atari games and heading into the real world, this year was it.

In biotech, theres no doubt of AIs promise in drug discovery or medical diagnoses. In late 2019, a team used deep learning and generative modelssimilar to AlphaGo, the DeepMind algorithm that trounced humans at Go and wiped the Atari libraryto conjure over 30,000 new drug molecules, a feat chemists could only dream of. This year, the viral hurricane thats Covid-19 further unleashed AI-based drug discovery, such as screening existing drugs for candidates that may work against the virus, or newlydesigned chemicals to fight off SARS-CoV-2 infectionthe virus that causes Covid-19.

For now, we dont yet have an AI-designed drug on the market, an ultimate test for the technologys promise. However, although AI wasnt able to make a splash in our current pandemic battle, the scene is set for tackling the next oneand drug discovery as a whole.

In contrast, AI-based medical diagnosis had a resounding win. This year, the FDA approved a software that uses AI to provide real-time guidance for ultrasound imaging for the heart, essentially allowing those without specialized training to perform the test. The approval brings a total of 29 FDA-approved AI-based medical technologies to date. Even as the debate on trust, ethics, and responsibility for AI doctors cranked up in temperature, the Pandoras box has been opened.

Medicine aside, deep learning further honed its craft in a variety of fields. The neuroscience-AI marriage is one for the ages with no signs of fracture. Outside the brain, AI also gave synthetic biology a leg up by parsing the interactions between genes and genetic networksa mind-bending, enormously complex problem previously only achieved through trial and error. With help from AI, synthetic biologists can predict how changes to one gene in a cell could affect others, and in turn, the cells biochemistry and behavior. Bottom line: it makes designing new biological circuits, such as getting yeast to pump out green fuels or artificially hoppy beer, much easier.

But the coup de grce against AI as an overhyped technology is DeepMinds decimation of a 50-year-long challenge in biology. With a performance that shocked experts, DeepMinds AlphaFold was able to predict a proteins 3D structure from its amino acid sequencethe individual components of a proteinmatching the current gold standard. As the workhorses of our bodies, proteins dictate life. AlphaFold, in a sense, solved a huge chunk of the biology of life, with implications for both drug discovery and synthetic biology.

One more scientific brilliance this year is the use of light in neuroscience and tissue engineering. One study, for example, used lasers to directly print a human ear-like structure under the skin of mice, without a single surgical cut. Another used light to incept smell in mice, artificially programming an entirely new, never-seen-in-nature perception of a scent directly into their brains. Yet another study combined lasers with virtual reality to dissect how our brains process space and navigation, mentally transporting a mouse to a virtual location linked to a reward. To cap it off, scientists found a new way to use light to control the brain through the skull without surgerythough as of now, youll still need gene therapy. Given the implications of unauthorized mind control, thats probably less of a bug and more of a feature.

Were nearing the frustratingly slow, but sure, dying gasp of Covid-19. The pandemic defined 2020, but science kept hustling along. I cant wait to share what might come in the next year with youmay it be revolutionary, potentially terrifying, utterly bizarre* or oddly heart-warming.

* For example, Why wild giant pandas frequently roll in horse manure. Yes thats the actual title of a study. Yes, its a great read. And yes, its hilarious but has a point.

I am seeing tons of hair loss, Mona Gohara says.

Patients come to Gohara, a dermatologist and professor at the Yale School of Medicine, for all kinds of reasons from skin cancer screenings to cosmetic procedures. But this year more than ever, theyre worried about their hair.

Its not a coincidence. Stress like, say, that brought on by living through a deadly pandemic is known to cause hair loss. Ordinarily, 90 percent of the hairs on our head are in the growing cycle; 10 percent are in the shedding cycle, Gohara explained. But when were subject to some type of physiologic or emotional stress, that cycle shifts to where the shed outweighs the grow. The result: people notice a massive, massive shed.

And those stray hairs are part of a bigger trend. At this point, millions of Americans have spent nine months living through a public health nightmare and an unprecedented economic crisis at the same time. They have also had to cope with all this while avoiding gatherings, limiting physical contact, and, when possible, staying inside their homes. Put together, the isolation and anxiety of life in 2020 have brought with them numerous side effects. For one, they might be doing weird things to our bodies.

If youve noticed your menstrual cycle is more irregular this year, for example, youre not alone: More patients are reporting irregular periods since the pandemic began, Mary Jane Minkin, an OB-GYN who teaches at the Yale School of Medicine, told Vox. The likely culprit, as with hair loss, is the anxiety of living in such a difficult and uncertain time. When stressors come into play, Minkin said, we end up with screwy periods.

If youve spotted more gray hairs on Zoom calls, there may be a pandemic-related explanation for that too. And according to some, life in lockdown may even be changing peoples body odor.

Those are just some of the smaller effects. Some experts are also concerned because isolation has documented effects on health, increasing the risk of cardiovascular disease and even death. Humans are considered a social species, Julianne Holt-Lunstad, a professor of psychology and neuroscience at Brigham Young University who studies the impact of social relationships on health, told Vox. When we lack proximity to others, and particularly trusted others, this creates a heightened state of alert or stress which, over time, can have harmful effects on our bodies.

To be clear, none of this is an argument for getting rid of pandemic-related restrictions after all, the effects of Covid-19 on the body can be far more severe than the effects of isolation.

But the rise of pandemic periods, weird smells, and other bodily indignities are a reminder that Americans are going through something right now that most of us have never experienced before. And that takes its toll in a lot of ways some of them stranger than others.

Lets talk about periods first. Trend pieces about menstrual changes either irregularity or worsened symptoms like cramps began popping up in the spring. A couple of weeks into the stay-at-home order in Washington State, where I live, I woke up in the middle of the night with the worst cramps Ive ever had, Colleen Stinchcombe wrote at Self in May.

And while its likely too soon for any published research on the impact of the pandemic on menstruation, Minkin isnt the only one to see increased reports of irregularity among her patients. Its common for us to see patients with changes in their menstrual cycle, but anecdotally, it seems like its been happening more over the last six months, Beth Schwartz, an OB-GYN at Thomas Jefferson University Hospital in Philadelphia, told the Washington Post in August.

These changes arent necessarily surprising, Minkin told Vox. Most people think that the ovaries and the uterus regulate periods, she said. But actually, the boss is sitting in our brain.

Specifically, its the hypothalamus and the pituitary gland that control the ovaries, regulating their hormone production, which in turn regulates the menstrual cycle. Its our nice, regular hormonal activity from the hypothalamus and the pituitary which stimulate the ovaries to do their thing appropriately and get us nice, regular periods, Minkin said.

And when were under stress, that can disrupt the functioning of the hypothalamus and pituitary, leading to irregularity. Researchers have noticed a similar effect among young people who go away to college and often experience irregular periods as they adjust to a new environment and a new set of worries and pressures.

The good news, Minkin said, is having an irregular period generally isnt dangerous. When her patients report irregularity, shell typically test their thyroid function and levels of certain hormones to rule out conditions like polycystic ovary syndrome, but as long as everythings normal, no treatment is needed. If the irregularity is especially bothersome, people can take hormonal contraception to regulate their periods, Minkin said. Once we get through things and peoples lives get back toward normal, most folks are probably going to regulate themselves just fine.

But irregular periods arent the only strange symptom people are reporting after months of reduced contact with others. Another is body odor some say theyve started to smell worse, or just different, since the pandemic began.

I am a man who prides himself on smelling fresh and fancy free at all times, Joseph Lamour wrote at Mic in July. But during the pandemic summer, he became so limburger-esque that my own odor woke me up in the middle of the night.

As with periods, theres not yet published research on changes in body odor during the pandemic. But anecdotal reports of the issue have gotten back to Julie Horvath, head of the Genomics and Microbiology Research Lab at the North Carolina Museum of Natural Sciences and a professor at North Carolina Central University. An expert in primate genetics who expanded into studying microbes and odor (I never thought I would be the armpit researcher, she says), Horvath explains that a big factor in the way we smell is our skin microbiome, or the mix of bacteria, fungi, and viruses that live on our skin.

When youre in your home, youre now coming into contact more with maybe your pets and your family, who you didnt see as many hours a day, she told Vox. This means were exchanging microbes with a different group of people (and animals) than usual, which could affect our smell. Spending more time indoors can also affect the microbiome, as can wearing different types of clothes synthetic fabrics can host different kinds of microbes than cotton, for example. And a lot of people have changed their style (if you can call it that anymore) during the pandemic. When I talk to people, maybe theyre wearing a nice shirt, but now they have jeans or sweatpants on, Horvath said.

Stress can also affect the microbiome, Horvath said. A specific set of glands, the apocrine glands, release sweat when youre nervous. That sweat contains different compounds from sweat that comes from the ecrine glands, which get to work when youre too hot. And if your apocrine glands found in the armpit and a few other places on the body are highly active, then they are providing a different food source to some of those microbes there, and maybe youre promoting the growth of some that smell different than what they wouldve before, Horvath said.

But the microbiome doesnt just affect the way we smell. Beneficial bacteria on our skin create a protective barrier, Horvath explained. If you have these good, beneficial microorganisms that are on your skin, eating oil or sweat and living there happily, theyre taking up residence, she said. Then, if something lands on your skin that can make you sick a staph bacterium, for example then it cant take hold very quickly, because your beneficial organisms are going to outcompete it for resources.

Washing your hands with soap and water just washes away the lop layer of microbes, potentially allowing some of the good ones to stick around. But hand sanitizer kills the microorganisms on your skin, the good along with the bad, Horvath said. Thus, using too much hand sanitizer during the pandemic could leave us more vulnerable to staph, acne, or other infections down the road.

Airborne spread of the coronavirus in close contact is the main danger in the pandemic, but we still need to wash our hands, too. Horvath recommends using soap and water when possible to help maintain a healthy microbiome. Beyond that, habits like eating a healthy diet could be good for your microbial balance, though they may or may not help you smell better. Spending time outside if you can is also a good idea, Horvath said. Certain organisms that are outside in the soil are actually beneficial for your overall body.

Beyond weird smells and irregular periods, the isolation of this year has brought with it other physical changes for many. In addition to hair loss, a proliferation of gray hair is a common complaint one that can also likely be pinned on stress, as Deanna Pai reports at Medium. While the mechanism by which stress causes graying isnt fully understood, one recent study in mice found that stress led to the death of stem cells that produce melanocytes, the cells in hair follicles that produce pigment.

Gray hair isnt reversible (except with dye), Pai points out, but managing stress as much as anyone can during a pandemic can help slow the process.

Stress could also be making our skin look worse, Gohara, the dermatologist, said. It causes an increase in the hormone cortisol, which wreaks cosmetic havoc on your skin and can lead to anything from dryness to puffy eyes, she explained. Everything just looks worse with a surge in cortisol.

An increase in stress can also lead to more acne, something also exacerbated by the friction of wearing a mask (hence the 2020 neologism maskne, or breakouts on the lower part of the face linked to mask-wearing). Luckily, unlike gray hair, much of this is reversible you can combat maskne by washing masks in the same gentle cleanser you use for your face, Gohara said, and using a product with salicylic acid or benzoyl peroxide. For hair loss, meanwhile, she sometimes prescribes supplements, but also reassures patients that when it comes to shedding, eventually the cycle is going to re-equilibrate itself and your hair will be back on track.

While things like hair loss are typically harmless, if annoying, the way we live in 2020 could be causing more serious issues too.

Researchers have long known that isolation the condition of having little or no contact with other people and loneliness the subjective feeling of being alone, regardless of how much contact with people one has can be harmful, Holt-Lunstad, the psychologist, said. For example, in one 2015 analysis, she and her coauthors found that isolation was associated with a 29 percent increased likelihood of mortality, while loneliness was associated with a 26 percent increase.

There are a couple of ways that loneliness can potentially hurt our health. For one, friends and loved ones can influence us to take better care of ourselves having someone who encourages you to get to bed, or eat fruits and vegetables, or quit smoking, is good for our health, Holt-Lunstad said.

But many studies actually control for lifestyle factors like smoking and diet, and still find that loneliness and isolation have a negative effect. One reason, some researchers believe, is that our brains have adapted to expect proximity to others, and particularly trusted others, Holt-Lunstad said. When they arent around, the brain signals other parts of the body to go into a heightened state of alert. That can lead to changes in heart rate and blood pressure that could increase our risk of cardiovascular disease. But it could also lead to systemic inflammation in the body, which in turn has been linked to a host of mental and physical problems, Holt-Lunstad said, from Alzheimers disease to, troublingly, increased susceptibility to viruses.

These impacts are especially concerning because some early research has found high rates of loneliness and isolation during the pandemic. In an August survey, for example, two-thirds of adults reported social isolation, and more than 7 in 10 said the pandemic had made it harder to connect with friends.

Luckily, there are ways to reduce isolation, even during a time of social distancing. In a study this summer sponsored by the neighborhood-focused social network Nextdoor, Holt-Lunstad and her colleagues found that performing small acts of kindness for neighbors, such as bringing them groceries or checking in on them over the phone, was associated with a significant drop in loneliness 1 in 10 participants felt lonely at the beginning of the study, while just 1 in 20 felt the same at the end.

But it cant all be on individuals to fix their isolation during this very lonely time. Instead, Holt-Lunstad has advocated for policymakers to pay more attention to peoples social needs throughout the pandemic and recovery, including increased funding to help students and older people, who may be especially vulnerable to loneliness right now. And while funding for anything remains a fraught subject in Congress, Holt-Lunstad writes at Health Affairs that decisions should be based on scientific evidence of benefits and drawbacks to our well-being, not solely on economic costs and convenience.

Some of the smaller effects of pandemic living may dissipate naturally when this time in our lives is over. When it comes to issues like irregular periods, for example, the biggest takeaway is dont panic, Minkin says. We will get back to normal.

But for other, larger problems, like isolation and its serious effects on the body, the pandemic could be a wake-up call. My hope is now that we have all experienced, in some degree or another, this feeling of isolation and loneliness, that there may be greater awareness and less stigma, Holt-Lunstad said.

Give the gift of understanding

In April, Vox launched a way for readers to support our work with financial contributions and we've been blown away by the response. This year, support from our founding contributors has helped us create projects that millions relied on to understand a year of chaos, and to keep their families safe. Support from our readers helps us rely less on advertising, and keep our resource-intensive work free for everyone who needs it. We want to add 2,020 more founding contributors to our supporter base by the end of the year. Help us reach our goal by making a contribution to Vox today, from as little as $3.

Following the harassment of Christian Cooper in Central Park in May 2020, Black birders created #BlackBirdersWeek to celebrate Black nature enthusiasts and highlight their belonging in outdoor spaces. Since then, dozens of campaigns have emerged to amplify and appreciate Black academics, scientists, and naturalists.

Next up is #BlackInMarineScienceWeek, running from November 29th to December 5th.Led by founder Dr. Tiara Moore and organizers Amani Webber-Schultz, Dr. Camille Gaynus, Carlee Jackson, Al Troutman, Jasmin Graham, Jeanette Davis, Kris Howard, Leslie Townsell, Kaylee Arnold, and Jaida Elcock, this week represents an opportunity for community building and improved representation.

There are few Black folks in ecology and even fewer in marine ecology, says Arnold, a science communicator and disease ecologist. The network that Ive gained through organizing this week is phenomenal. Meeting other Black marine scientists and showing that to the world, especially young Black folks, is a way to say we exist, were here. We have a full day dedicated to young kids, which is unique and exciting.

The organizers hope that the week will help normalize Black folks doing marine research, inspire younger generations, and remind everyone to check their preconceived notions.

"When I say I study sharks people seem concerned about my swimming or my hair, [and] sometimes respond with 'Oh, thats super interesting'... I dont know if that's because it's unusual for people to study sharks or because Im Black and I study sharks, recalls Elcock, an elasmobranch movement ecologist, science communicator, and co-founder of Minorities in Shark Science. Science is for everybody. People say there isn't diversity because [Black] people arent interested... thats clearly not true theres a whole week dedicated [to it]."

Discussion this week will address the fact that exclusion, not lack of interest, led to todays lack of representation. Centuries of segregation and underinvestment in Black neighborhood pools led to, and are perpetuated by, these incorrect and harmful ideas.

My grandparents and my mom said there were just no pools for her to go to... I had a very different experience. Despite people trying to push us out of the water and science, we persevered, and now we get to break down those stereotypes, notes Arnold.

Black in Marine Science Week is here to do just that, showcasing organizers and participants from every imaginable marine science niche, all shaping how society views the oceans and its inhabitants.

There's more Black folks than even we know and are showcasing. I hope that if the media picks up on the number of us as well, and has better representation. Seminar series are extremely white, and now you have a resource of people you can invite instead, emphasizes Arnold, pointing to the necessity of non-Black marine scientists to step up and ensure representation continues beyond this joyous and educational week.

Adrenomyeloneuropathy is a rare genetic neuro-degenerative disease. Adrenomyeloneuropathy is the adult onset of adrenoleukodystrophy caused by the mutation in ABCD1 gene occurs usually in young boys. Adrenomyeloneuropathy disease affect the nerve cells in the spine and brain and the adrenal glands. Adrenomyeloneuropathy symptoms includes stiffness, weakness and pain in the legs. Adrenomyeloneuropathy is also known as progressive spastic paraparesis. Damage to the nerves of the legs which causes unsteadiness and fall, also the bladder, bowel and sexual organs are affected by the adrenomyeloneuropathy. Rare diseases affect vast numbers of people, with current data representing 30 million sufferers in the EU alone and 30 million affected in the US. There is no cure to Adrenomyeloneuropathy.
