NASA's Orion Spacecraft Has Reached a Record Distance From Earth
At the halfway point in NASA's Artemis 1 mission, the unpiloted Orion moonship is chalking up a near-flawless flight. Monday afternoon, Orion reached a point in its "distant retrograde orbit around the moon some 268,562 miles from Earth - nearly 43,000 miles above the lunar surface - setting a new distance record for human-rated spacecraft. "The spacecraft is operating just tremendously well so far, and we're really happy with its performance overall across all the subsystem areas," said Howard Hu, NASA's Orion program manager.

Wildlife Comedy Awards Unveil This Year's Finalists With Amusing Animal Antics
The bears are smiling, the birds look confused, and the public is once again howling with laughter — the finalists for the 2025 Nikon Comedy Wildlife Awards have been announced, and the shortlist is as brilliant as ever. Out of nearly 10,000 entries from 108 countries, judges have selected 40 standalone photographs, 10 videos, and three photographer portfolios that capture animals at their most unintentionally hilarious. Think: a monkey mid-pratfall, an owl with impeccable side-eye, or a flamingo looking oddly... headless. This year’s finalists include a wildly expressive range of creatures — from a grumpy turtle to a surprised squirrel — each caught in a moment that feels oddly relatable. No digital trickery allowed either: AI and image manipulation are strictly banned, making every submission a genuine, real-world shot. “These inspiring and funny photos and videos do just that,” said co-founder Tom Sullam, a British photographer who helped launch the competition in 2015 to blend humor with conservation. “They reach people in more countries than ever before, helping us raise awareness of animal and habitat conservation — and crucially, highlight the fundamental importance of having wildlife on our planet and in our lives.” Organized in partnership with Nikon, the competition has grown into a global phenomenon. Entry is free and open to photographers of all levels, including a Young category (up to 25 years old), a Junior category (16 and under), and a People's Choice Award based on public votes from December 10, 2025, to March 1, 2026. This year’s overall winner — along with category winners and highly commended mentions — will be revealed at a ceremony in London on December 9. All finalists will then go on display at a free exhibition in a London art gallery from December 10 to 14. The top prize includes a Kenyan safari and photography gear, but for many, it’s about more than just accolades. Finnish photographer Tapani Linnanmäki took last year’s People’s Choice award for his photo of a white-tailed eagle caught mid-shake, feathers flying in every direction. And in a crossover moment between wildlife and the AI conversation, photographer Miles Astray submitted a now-famous image of a real flamingo that appeared headless — an image that fooled even AI image judges and became a top contender in an artificial intelligence art competition last year. That same image is now a Comedy Wildlife finalist. “This competition is a celebration of joy, timing, and patience,” said Stefan Maier, senior marketing manager at Nikon Europe. “These images combine wit and wonder to celebrate nature’s character, while emphasizing the urgency of conservation.” In keeping with that mission, the competition donates 10 percent of its net revenue each year to a conservation charity. In 2025, the chosen partner is once again the Whitley Fund for Nature, a UK-based nonprofit that supports grassroots wildlife conservation in the Global South. So, what should the public expect from this year’s finalists? “They’re brilliant,” said Maier. And judging from the bear with a toothy grin and a hornbill mid-squawk, that’s no exaggeration. Public voting opens in December — and if past years are any indication, it’ll be hard to choose just one favorite.

Veteran Who Spent 10 Years in Prison Launches Falconry Project to Support Mental Health
A military veteran from Reading who battled PTSD and spent a decade in prison has now found healing in an unexpected place — the woods, with a hawk on his arm. And now he’s sharing that experience with others facing mental health challenges. Darren Horvath, who served in the Middle East during the first Gulf War when he was just 17, said the trauma of what he experienced on the frontline stayed with him long after he returned home. Struggling to cope with PTSD, he attempted suicide, leaving him permanently paralysed in his right arm. “Life got worse,” he said, describing the period that followed. After setting fire to two parked cars, he was sentenced to prison under the controversial Imprisonment for Public Protection (IPP) system. Although his sentence was supposed to be just two years, he ended up serving 10. The IPP sentence, used between 2005 and 2012, was intended to keep serious offenders off the streets. But it became widely criticised for trapping low-level offenders in the system indefinitely. Release depended on a Parole Board review, which many never received. The law has since been scrapped. Raised in care, Horvath joined the Army at age 16 and served in the Life Guards regiment. He said he enjoyed his time in the military but found it difficult to process his actions in combat. “It was kill or be killed,” he said of the frontline. But back home, that mindset led to years of inner conflict and trauma. While in prison, Horvath joined a falconry programme and found unexpected solace in working with birds of prey. That experience planted the seed for what would eventually become The Raptor Project — a group he now runs to support people with mental health struggles. Out on a walk with Antal, his six-month-old hawk, Horvath described how much the bond with the bird has helped him. “It’s like a huge weight is taken off my shoulders when I’m in the woods with him,” he said. “When I’m out flying with him, and the kind of connection and the bond we’ve got — it’s kind of special too. It brightens me up. There’s a glowing and warmth inside, and I basically wouldn’t mind everyone else feeling like that too.” The project offers that sense of connection to others who might be struggling. Katie, who participates in the programme, said it’s changed her outlook. “Suffering with anxiety, depression and anxiety can be very challenging,” she said. “But it’s giving us all a reason to get up and go. It gives me a huge amount of purpose in life.” The Raptor Project is one of many grassroots efforts aiming to support mental health outside traditional therapy settings — this one through feathers, fresh air, and a quiet connection between human and bird. For Horvath, the journey has been long, but it’s finally taking flight.

New Study Finds Cholesterol-Lowering Drugs May Reduce Dementia Risk
Cholesterol-lowering drugs like statins and ezetimibe may do more than just protect your heart — they could also help reduce the risk of dementia, according to new research involving nearly one million people. The study, led by researchers at the University of Bristol and Copenhagen University Hospital, used genetic data to explore the long-debated link between cholesterol and cognitive decline. While previous research has hinted at a connection between "bad" cholesterol and dementia, this is one of the most comprehensive studies to date supporting that association. "The present data suggests that cholesterol lowering earlier in life likely will reduce the risk of dementia later in life," the researchers wrote in the paper, published in the journal Alzheimer’s & Dementia. Rather than tracking patients who were already taking statins, the researchers took a different approach: they studied people with genetic variants that naturally lower cholesterol. This method — known as Mendelian Randomization — allows scientists to study long-term health outcomes without the complications of lifestyle factors like diet or exercise, which can be difficult to control for in observational studies. “What our study indicates is that if you have these variants that lower your cholesterol, it looks like you have a significantly lower risk of developing dementia,” said clinical biochemist Liv Tybjærg Nordestgaard, who worked on the study during her time at the University of Bristol. By comparing genetic profiles across a massive dataset, the team was able to show that people with cholesterol-lowering genes were less likely to develop dementia — strongly suggesting that the biological mechanisms involved in lowering LDL cholesterol also influence cognitive health. The researchers believe the link may lie in how cholesterol affects blood vessels. Atherosclerosis — the build-up of fatty deposits in the arteries — is a known driver of heart disease, but it may also damage blood flow to the brain. That can, in turn, contribute to certain forms of dementia, particularly those associated with reduced oxygen and nutrients reaching brain tissue. While the study doesn’t prove that taking statins will prevent dementia, the researchers say it builds a strong case for clinical trials to test that hypothesis directly. “It would be a really good next step to carry out randomized clinical trials over 10 or 30 years, for example, where you give the participants cholesterol-lowering medication and then look at the risk of developing dementia,” said Nordestgaard. The findings add weight to the idea that managing heart health — even early in life — could be one of the most effective strategies for preserving brain health in later years.

Scientists Detect ‘Seeds of Life’ Outside Milky Way Using James Webb Space Telescope
For the first time in history, scientists have detected complex organic molecules. It's the same kinds that help form life on Earth in a galaxy beyond our own. Using the James Webb Space Telescope (JWST), researchers have identified methanol, ethanol, and even the main ingredient in vinegar in a star-forming region of the Large Magellanic Cloud, a nearby galaxy about 160,000 light-years away. These molecules were spotted frozen in ice around a young star called ST6. The discovery is a major breakthrough in astrochemistry. While such molecules have been seen before in our galaxy, this is the first time several of them — including ethanol, methyl formate, and acetaldehyde — have been confirmed in ice outside the Milky Way. One of them, acetic acid, had never been conclusively detected in space at all. “These are molecules we associate with the building blocks of life,” said Marta Sewilo, the lead researcher from the University of Maryland. She and her team published the findings after analyzing data from JWST’s Mid-Infrared Instrument (MIRI), which is capable of detecting faint molecular signatures in the frozen dust where stars are born. The region they studied is filled with thick clouds of dust and ice, creating a kind of natural chemistry lab where organic molecules can form on the surfaces of tiny grains. What makes this discovery especially surprising is that the Large Magellanic Cloud has far fewer heavy elements than the Milky Way. It’s also bombarded by intense ultraviolet radiation — a hostile setting where fragile molecules like these would normally be expected to break apart. “The detection of icy COMs in the Large Magellanic Cloud provides evidence that these reactions can produce them effectively in a much harsher environment than in the solar neighbourhood,” said Will Rocha, a co-author from Leiden University. COMs — short for complex organic molecules — form when atoms and simple molecules stick to the surface of cold dust grains and react with one another. Once temperatures rise, as in the early stages of star formation, those molecules can evaporate into gas, seeding their surroundings with chemical complexity. Among the molecules identified in this study were methanol, ethanol, methyl formate, acetaldehyde, and acetic acid. The team also saw signs of glycolaldehyde, a sugar-related compound and a potential precursor to molecules like RNA. “The harsh conditions tell us more about how complex organic chemistry can occur in these primitive environments where much fewer heavy elements like carbon, nitrogen and oxygen are available for chemical reactions,” Sewilo said. The significance goes beyond the immediate discovery. Because the Large Magellanic Cloud has low metallicity — a lower abundance of heavy elements — it resembles the types of galaxies that existed in the early universe. This makes it an ideal test case for how organic molecules might have formed billions of years ago, long before our own solar system took shape. While the detection of these compounds doesn’t prove that life exists elsewhere, it does suggest that the chemical ingredients of life are not unique to the Milky Way — and may be far more common than previously thought. “These findings help us understand how complex chemistry emerges in star-forming regions across the universe,” said Sewilo, who hopes to expand the research to more stars in both the Large and Small Magellanic Clouds. For scientists searching for life’s origins in the universe, the discovery is a powerful reminder that nature’s chemical toolkit may be universal — and much more resilient than we imagined.

Scientists Find a Way to See ‘Nature’s Invisible Glue’ Using Gold, Salt, and Light
In Sweden, a team of researchers has figured out a surprisingly simple way to make one of nature’s most mysterious forces visible — using gold flakes, salt water, and a beam of light. At Chalmers University of Technology, physicists have built a new experimental platform that lets scientists see the invisible forces that hold the tiniest particles together. These forces, which help explain everything from why dust sticks to surfaces to how a gecko walks across a ceiling, usually operate on a scale too small for the human eye to detect. But now, with a drop of salty water and some microscopic gold flakes, those interactions can be seen as flashes of shimmering colour. “What we are seeing is how fundamental forces in nature interact with each other,” said Michaela Hošková, a PhD student at Chalmers and lead author of the new research published in PNAS. “Through these tiny cavities, we can now measure and study the forces we call 'nature’s glue' — what binds objects together at the smallest scales.” In the lab, Hošková demonstrates how it works. She starts with a glass container holding millions of microscopic gold flakes suspended in a salt solution. Using a pipette, she places a droplet of the liquid on a thin glass plate coated in gold, under a standard optical microscope. Almost immediately, the flakes are drawn toward the surface — but they don’t touch it. Instead, they hover nanometers away, creating minuscule gaps so small that they trap light between the surfaces. As light reflects inside these cavities, the flakes start to shimmer in a range of colours, from red to green to gold, depending on how the light bounces within the space. These floating flakes essentially become sensors. They make it possible to measure the tiny, often competing, forces acting on particles in liquids. At the heart of the experiment are two forces in delicate balance. One is the Casimir effect — a strange quantum force that pulls the flakes toward the surface. The other is an electrostatic force, created by charged particles in the salt water, which pushes the flakes away. When the two forces cancel each other out, a phenomenon called “self-assembly” occurs, and the flakes lock into a perfectly balanced position, separated from the surface by just 100 to 200 nanometers. “Forces at the nanoscale affect how different materials or structures are assembled, but we still do not fully understand all the principles that govern this complex self-assembly,” said Hošková. “If we fully understood them, we could learn to control self-assembly at the nanoscale. At the same time, we can gain insights into how the same principles govern nature on much larger scales, even how galaxies form.” The platform, built with help from Chalmers’ Nanofabrication Laboratory and Materials Analysis Laboratory, is the result of several years of work in Professor Timur Shegai’s research group. The team first discovered in 2020 that two gold flakes could create a self-assembled optical resonator. Since then, they’ve refined the setup into a fully functioning tool for studying nanoscale interactions. The goal now is to use it across a wide range of scientific fields. “The method allows us to study the charge of individual particles and the forces acting between them,” said Shegai. “Other methods for studying these forces often require sophisticated instruments which cannot provide information down to the particle level.” Because the setup is so simple and fast — just two thin glass plates and a halogen lamp — it could become a practical tool for research in physics, chemistry, and materials science. But it also has potential for much more everyday uses, like improving the stability of cosmetics or enhancing how medicines travel through the body. Understanding how individual particles behave in liquid could also help design more effective biosensors, water filters, or medical diagnostics. “The fact that the platform allows us to study fundamental forces and material properties shows its potential as a truly promising research platform,” said Shegai. As Hošková zooms in on one of the flakes through the microscope, its colours shift and glimmer, revealing the subtle push and pull of invisible forces at play. “What I find most exciting is that the measurement itself is so beautiful and easy,” she said. “The method is simple and fast, based only on the movement of gold flakes and the interaction between light and matter.”

Could a Common Vitamin Cut Skin Cancer Risk In Half?
A common, inexpensive vitamin supplement may offer real protection against one of the most frequent forms of cancer. A new study involving more than 33,000 U.S. veterans has found that nicotinamide, a form of vitamin B3, can significantly reduce the risk of developing certain types of skin cancer — particularly when started early. Stronger evidence for a simple supplement Since 2015, dermatologists have occasionally recommended nicotinamide to patients with a history of skin cancer. That advice stemmed from a much smaller clinical trial that included just 386 participants, which found fewer new cancers among those taking the vitamin. The latest research, conducted using data from the U.S. Department of Veterans Affairs, strengthens that evidence on a far larger scale. Because nicotinamide is listed on the VA’s official formulary, researchers were able to track its use and compare outcomes among tens of thousands of patients. Significant drop in skin cancer risk The study analyzed the medical records of 33,833 veterans, of whom 12,287 took 500 milligrams of nicotinamide twice daily for more than 30 days. Compared with those who didn’t take the supplement, nicotinamide users saw a 14% overall reduction in skin cancer risk. For patients who began taking it after developing their first skin cancer, the protective effect was far greater — a 54% reduction in the risk of future cases. However, the benefit decreased for those who started the vitamin only after developing multiple cancers. The strongest effect was observed against cutaneous squamous cell carcinoma, one of the two most common types of nonmelanoma skin cancer. Starting earlier may matter most “There are no guidelines for when to start treatment with nicotinamide for skin cancer prevention in the general population,” said Dr. Lee Wheless, the study’s corresponding author and an assistant professor of dermatology and medicine at Vanderbilt University Medical Center. “These results would really shift our practice from starting it once patients have developed numerous skin cancers to starting it earlier,” he said, noting that better methods are still needed to identify who benefits most. “Roughly only half of patients will develop multiple skin cancers.” Mixed results in transplant patients The team also examined 1,334 transplant recipients, who face higher skin cancer risks due to immune suppression. In this group, nicotinamide’s overall effect wasn’t statistically significant, though early use appeared to reduce the incidence of squamous cell carcinoma. A low-cost option for prevention Nicotinamide is inexpensive, widely available over the counter, and generally well tolerated, making it an appealing preventive option for people at high risk of recurrent skin cancer. The study was supported by a Department of Veterans Affairs grant and conducted in collaboration with researchers from Vanderbilt University. For dermatologists, the findings could mark a shift in prevention strategies — from waiting until patients have several skin cancers to intervening after the first one. For patients, it suggests something simple and safe might make a measurable difference in keeping their skin healthy.

70 Rare Horses Rescued in Major Animal Welfare Operation
Seventy rare Icelandic horses and foals have been rescued from poor conditions in a 15-month operation led by UK animal charities, following public concern about the welfare of semi-feral herds in Devon. The Mare and Foal Sanctuary, which coordinated the rescue alongside the RSPCA and World Horse Welfare, said the operation began in May 2024 after reports surfaced about unmanaged herds spread across several sites. Many of the animals were found in distressing conditions, including mares in foal sharing space with fighting stallions and colts. Some horses had life-threatening injuries. “There was unmanaged breeding among the herds,” the sanctuary said in a statement. “Our staff found in-foal mares living alongside fighting colts and stallions.” The rescue took place in stages, with injured and at-risk horses removed first. Healthier mares and foals were taken later. The process was vet-led throughout, and the sanctuary confirmed that the horses’ owner cooperated fully, signing over the animals voluntarily. Thirteen of the horses are still in the care of The Mare and Foal Sanctuary. The organization is now asking supporters to help name one of the rescued colts, a four-year-old with distinctive blue eyes and striking markings. “He’s a very handsome young colt,” said campaigns manager Pippa Quelch. “He came to us a few weeks after his birth in the summer, with his dam Mavis and another Icelandic mare and colt foal. They were completely unhandled on arrival... this little foal was quite reserved around people at first. He's now relaxed and confident and loves to be groomed and scratched.” Quelch said the care team has “fallen in love” with the young colt, and the winning name will be announced on 30 October. There are only about 1,000 registered Icelandic horses in the UK, according to the sanctuary, making the rescued group particularly rare. The breed is known for its hardiness, gentle temperament, and unique “tölt” gait — a smooth four-beat stride not seen in most other horses. The sanctuary is now focused on preparing the animals for future rehoming where appropriate, while ensuring their long-term health and welfare. The RSPCA called the operation “one of the most complex and sensitive horse welfare cases in recent years.”

Scientists Develop Breakthrough Vaccine to Protect Elephants From Deadly Virus
Veterinary scientists in the UK have developed a promising new vaccine that could protect young elephants from one of their deadliest viral threats, offering a lifeline to conservation efforts worldwide. Elephant endotheliotropic herpesvirus, or EEHV, is a fast-acting and often fatal disease that affects elephants both in the wild and in captivity. It’s particularly lethal to calves, and until now, there has been no vaccine or cure. But that may be changing. A team of researchers from the University of Surrey, Chester Zoo, and the UK’s Animal and Plant Health Agency have created a two-dose vaccine that has shown strong early results. Their study, published in Nature Communications, marks what scientists are calling a “landmark moment” in the fight to protect the species. “This is a landmark moment in our work to develop safe and efficacious vaccines,” said Professor Falko Steinbach, senior author of the study and a veterinary immunologist at the University of Surrey. “For the first time, we have shown in elephants that a vaccine can trigger the type of immune response needed to protect them against EEHV.” The vaccine works by delivering a first dose containing a harmless, inactivated version of the virus. A booster shot follows to enhance the animal’s immune response. Trials showed the vaccine was not only safe, with no side effects, but also triggered the type of strong immune reaction scientists hoped for. Chester Zoo, which has lost five elephants to EEHV in recent years, played a key role in the vaccine’s development. “EEHV has taken the lives of so many elephants, both in human care and in the wild, but this vaccine offers hope,” said Dr. Katie Edwards, lead conservation scientist at the zoo. “We can’t yet say this will be the end of EEHV deaths, but we have taken a massive step towards that goal.” Researchers tested the vaccine by comparing blood samples of vaccinated elephants against those who hadn’t received it. The results showed a marked increase in immune protection, suggesting the vaccine could be used to prevent further deaths and support the long-term health of conservation herds. EEHV is considered one of the leading causes of death for Asian elephant calves, and outbreaks often strike without warning. The virus targets blood vessels and organs, leading to sudden illness and, frequently, death within hours or days. Because it’s so difficult to detect early, prevention through vaccination is considered one of the most effective long-term solutions. While it’s still early days, conservationists say the new vaccine could be a gamechanger for breeding programs and elephant populations globally. Field trials and broader rollout will be key next steps, but the breakthrough offers a rare piece of good news for a species under significant pressure. For scientists and zoo staff who have watched young elephants die from EEHV, the development brings a renewed sense of hope. And for elephants themselves, it could be the protection they’ve long been waiting for.

Germany Leads Europe In Plastic Packaging Recycling Efforts
Europe generated nearly 80 million tonnes of packaging waste last year — but some countries are already smashing future recycling targets. New figures released by Eurostat show that the European Union produced 79.7 million tonnes of packaging waste in 2023, the equivalent of 177.8 kilograms per person. That’s down slightly from 2022, but up more than 21 kilograms compared to 2013. Packaging waste includes anything used to contain or deliver goods — such as plastic bottles, glass jars, food wrappers, pallets, or cans. Of the total generated, the biggest share came from paper and cardboard, making up 40.4 percent. Plastic followed at 19.8 percent, glass at 18.8 percent, wood at 15.8 percent, metal at 4.9 percent, and the remaining 0.2 percent classified as “other packaging.” Despite the sheer volume, some EU countries are making faster progress than others. Seven countries have already hit the EU’s 2030 target of recycling at least 70 percent of packaging waste. Leading the pack is Belgium, with a recycling rate of 79.7 percent — thanks in part to its long-standing “pay-as-you-throw” waste system. First introduced in 1995, the scheme charges households based on how much unsorted waste they produce, with rates in Flanders averaging 23 cents per kilogram. The aim is to nudge residents toward better recycling habits. Belgium also offers a voluntary deposit-return system for certain types of reusable packaging, such as glass bottles and industrial containers, according to the European Environment Agency (EEA). Hot on Belgium’s heels are the Netherlands and Italy, recycling 75.8 and 75.6 percent of their packaging waste, respectively. Czechia (74.8 percent), Slovenia (73.6 percent), Slovakia (71.9 percent), and Spain (70.5 percent) round out the list of early achievers. At the other end of the spectrum, Romania lagged far behind, recycling just 37.3 percent of its packaging waste in 2023. The European Parliament has previously noted that countries with lower GDPs often struggle to build waste treatment infrastructure that is both cost-effective and environmentally sound. Plastic bags also under scrutiny The EU is also cracking down on single-use plastic bags. Under its Plastic Bags Directive, member states are expected to cut consumption of lightweight plastic carrier bags to fewer than 40 per person by 2025. Belgium again came out on top, with just four plastic bags used per capita in 2023. Poland followed with seven, and Portugal with 14. But not everyone is on track. Latvia reported a whopping 209 plastic bags per person — more than five times the upcoming 2025 threshold. To encourage change, many retailers have stopped offering thin, single-use bags, replacing them with thicker, reusable versions. Why the push to reduce waste? The environmental and health costs of poor waste management are well documented. Burning waste has been linked to increased air pollution, while overflowing landfill sites can contaminate nearby water and soil. “Overall, the EU is slowly showing improvement toward recycling more and landfilling less,” according to the EEA. But it warns that meeting future waste goals “requires significant effort,” including phasing out non-recyclable products and improving separate waste collection systems. Although about 90 percent of the EU’s waste is processed within its borders, significant volumes are still exported — primarily for recycling. This practice has raised concerns about burdening lower-income countries with additional environmental risks. As the EU works toward its 2030 targets, the new data highlights the gap between leaders and laggards — and the growing urgency to move from managing waste to preventing it altogether.

Scientists Hail Vitamin D As Potential Breakthrough In Anti-Aging Research
A new study suggests that vitamin D — best known for supporting strong bones — might also help slow the aging process by protecting telomeres, the tiny caps at the ends of our chromosomes that prevent DNA damage. Researchers at Augusta University in the United States found that adults who took 2,000 international units (IU) of vitamin D daily for five years maintained longer telomeres compared with those who took a placebo. The findings raise hopes that the “sunshine vitamin” could play a role in promoting healthier aging. Why telomeres matter Each of our 46 chromosomes is tipped with a telomere, a structure that keeps DNA intact when cells divide. Over time, these protective caps shorten — and when they get too short, cells stop dividing and begin to die. Shortened telomeres are linked to age-related illnesses such as heart disease, cancer, and osteoarthritis. Chronic stress, smoking, and inflammation can speed up this shortening, while anti-inflammatory habits — including diet and exercise — may help preserve them. Because vitamin D has anti-inflammatory properties, researchers believe it may indirectly slow telomere damage. Inside the research The study followed 1,031 adults, with an average age of 65, over five years. Half were given a daily vitamin D supplement of 2,000 IU, while the others received a placebo. Scientists measured participants’ telomere lengths at the start, after two years, and again after four. At the end of the trial, those taking vitamin D showed 140 base pairs more in preserved telomere length compared with the placebo group. Since telomeres typically shorten by about 460 base pairs every decade, that difference could represent years of additional cellular “youth.” “This may not sound huge,” the researchers noted, “but it could be meaningful in slowing age-related cellular decline.” More than bone health Vitamin D plays several roles in the body beyond bone maintenance. It helps the immune system function properly, reduces inflammation, and has been linked to a lower risk of respiratory infections and autoimmune diseases. The study builds on previous evidence that vitamin D and anti-inflammatory diets, like the Mediterranean diet, may contribute to longer telomeres. Questions that remain Despite the promising data, scientists urge caution. Longer isn’t always better — excessively long telomeres may increase the risk of some cancers. And while the trial used 2,000 IU per day, that’s well above the standard recommended amount: 600 IU for adults under 70 and 800 IU for those over 70. Experts say the right dosage likely varies by person, depending on diet, lifestyle, and current vitamin D levels. The takeaway For now, researchers agree that vitamin D alone isn’t a miracle anti-aging solution. The best way to support telomere health — and healthy aging in general — remains straightforward: eat well, exercise, get enough sleep, avoid smoking, and manage stress. Still, for those who are vitamin D deficient or at risk of bone problems, supplements remain a smart and proven choice. As scientists continue to uncover how our cells age, vitamin D may emerge as one small but significant piece of the longevity puzzle.
