Participants who made these lifestyle changes were 31% less likely to develop the disease over six years. They also lost more weight and trimmed their waistlines compared to those following a standard Mediterranean diet alone.

Older mice with boosted levels of the protein were stronger, more energetic, and had healthier bones than untreated mice. Researchers say the findings could eventually lead to therapies that help people stay healthier and more independent later in life.

Those who gained weight instead faced higher risks — especially for heart failure — even though many patients discontinued the medications within a year. Tue, 19 May 2026 09:05:57 EDT https://www.sciencedaily.com/releases/2026/05/260518041432.htm https://www.sciencedaily.com/releases/2026/05/260517211451.htm Scientists in South Korea have discovered that a probiotic bacterium found in kimchi may help the body flush out tiny plastic particles before they can build up in organs. In lab tests, the kimchi-derived microbe clung tightly to nanoplastics even under conditions designed to mimic the human intestine, where other bacteria quickly lost their grip. Mon, 18 May 2026 05:59:47 EDT https://www.sciencedaily.com/releases/2026/05/260517211451.htm https://www.sciencedaily.com/releases/2026/05/260517211427.htm Scientists discovered that eating grapes can actually change how your skin behaves at the genetic level. After just two weeks of daily grape consumption, volunteers showed signs of improved skin protection and reduced oxidative stress from UV exposure. Researchers say the effects appear widespread, even though every person’s genes responded a little differently. Mon, 18 May 2026 19:31:33 EDT https://www.sciencedaily.com/releases/2026/05/260517211427.htm https://www.sciencedaily.com/releases/2026/05/260517030515.htm Studies suggest watermelon could be a hidden powerhouse for better health. Researchers found that people who eat watermelon tend to have higher-quality diets packed with more vitamins, fiber, and antioxidants — while consuming less added sugar and saturated fat. Another study showed watermelon juice may help protect blood vessel function and support heart health. Sun, 17 May 2026 08:56:21 EDT https://www.sciencedaily.com/releases/2026/05/260517030515.htm https://www.sciencedaily.com/releases/2026/05/260517030404.htm Scientists have discovered that the human body undergoes a dramatic internal transformation during extended fasting, with major changes appearing only after about three days without food. In a seven-day water-only fasting study, researchers tracked thousands of proteins in the blood and found widespread shifts affecting organs throughout the body — including the brain. While the body quickly switches from burning glucose to fat, the most intriguing biological changes linked to potential health benefits didn’t emerge until later in the fast. Sun, 17 May 2026 08:38:40 EDT https://www.sciencedaily.com/releases/2026/05/260517030404.htm https://www.sciencedaily.com/releases/2026/05/260517030326.htm A new nanotechnology treatment reversed Alzheimer’s symptoms in mice by restoring the brain’s natural cleanup system. The specially engineered nanoparticles helped clear toxic amyloid proteins from the brain and repair the blood-brain barrier, which normally protects and regulates the brain’s environment. In one striking experiment, elderly mice treated with the therapy later behaved like healthy younger mice. Sun, 17 May 2026 07:11:34 EDT https://www.sciencedaily.com/releases/2026/05/260517030326.htm https://www.sciencedaily.com/releases/2026/05/260515234803.htm Researchers have shown for the first time that malfunctioning mitochondria — the cell’s energy generators — may directly cause cognitive decline in neurodegenerative diseases. By creating a new tool that temporarily boosts mitochondrial activity in the brain, scientists restored memory performance in mouse models of dementia. The discovery hints that energy failure inside neurons could happen before brain cells die, potentially offering a new target for future Alzheimer’s treatments. Sat, 16 May 2026 09:30:59 EDT https://www.sciencedaily.com/releases/2026/05/260515234803.htm https://www.sciencedaily.com/releases/2026/05/260515234759.htm A major analysis of brain scans found that people with anxiety disorders have noticeably lower levels of choline, a nutrient crucial for healthy brain function. The strongest evidence appeared in the prefrontal cortex, the region tied to emotional control and decision-making. Researchers say the discovery is the first clear chemical brain pattern linked to anxiety and could eventually lead to new nutrition-based treatments. Sat, 16 May 2026 08:41:30 EDT https://www.sciencedaily.com/releases/2026/05/260515234759.htm https://www.sciencedaily.com/releases/2026/05/260515233346.htm Exercise may be training your brain just as much as your body. Researchers discovered that certain brain cells stay highly active even after a workout ends, and those lingering signals appear to help the body build endurance over time. In experiments with mice, blocking these brain cells prevented improvements in stamina, even when the animals still exercised normally. Sat, 16 May 2026 09:52:45 EDT https://www.sciencedaily.com/releases/2026/05/260515233346.htm https://www.sciencedaily.com/releases/2026/05/260515233343.htm Coffee may give your blood pressure a temporary jolt, but that doesn’t mean it’s secretly wrecking your heart. Researchers say caffeine can briefly raise blood pressure by stimulating your heart and tightening blood vessels, especially in people who don’t drink coffee regularly. But large studies involving hundreds of thousands of people found no strong evidence that moderate coffee drinking increases the risk of developing hypertension. In fact, coffee also contains natural compounds that may help blood vessels function better. Fri, 15 May 2026 23:33:43 EDT https://www.sciencedaily.com/releases/2026/05/260515233343.htm https://www.sciencedaily.com/releases/2026/05/260515233331.htm For years, “yo-yo dieting” has been blamed for wrecking metabolism and causing lasting damage, but a major new review says the fear may be wildly overblown. After analyzing decades of studies in humans and animals, researchers found little convincing evidence that losing weight and regaining it actually causes long-term harm. While regaining weight can erase some health improvements, it doesn’t appear to make people worse off than before. Sun, 17 May 2026 02:02:13 EDT https://www.sciencedaily.com/releases/2026/05/260515233331.htm https://www.sciencedaily.com/releases/2026/05/260515233322.htm A new study suggests microscopic particles from the gut may actively drive inflammation and chronic diseases associated with aging. Remarkably, gut particles from young animals appeared to counter some aging-related damage in older animals, hinting at new possibilities for future treatments. Sat, 16 May 2026 01:47:41 EDT https://www.sciencedaily.com/releases/2026/05/260515233322.htm https://www.sciencedaily.com/releases/2026/05/260515002201.htm Cannabis use among older adults is rising fast, but today’s marijuana is far more potent than many people realize — and experts warn the risks may be underestimated. Stanford Medicine specialists say modern cannabis can increase the chances of heart problems, falls, memory issues, dangerous drug interactions, and even addiction, especially for people over 65. Fri, 15 May 2026 08:18:42 EDT https://www.sciencedaily.com/releases/2026/05/260515002201.htm https://www.sciencedaily.com/releases/2026/05/260515002155.htm Scientists have uncovered evidence that serotonin — the same brain chemical boosted by many antidepressants — may actually worsen tinnitus. Using advanced light-based brain stimulation in mice, researchers identified a serotonin-driven circuit linked directly to tinnitus-like behavior. The findings may explain why some people experience louder ringing in their ears while taking SSRIs. Fri, 15 May 2026 07:11:38 EDT https://www.sciencedaily.com/releases/2026/05/260515002155.htm https://www.sciencedaily.com/releases/2026/05/260515002146.htm Scientists are uncovering a surprising link between hidden tooth infections and blood sugar problems. Deep infections around tooth roots can create chronic inflammation that spreads through the body and may interfere with insulin function. Studies found that people who underwent root canal treatment often experienced better blood sugar control and reduced inflammation afterward. The research suggests that treating an infected tooth could have benefits far beyond the mouth. Fri, 15 May 2026 00:21:46 EDT https://www.sciencedaily.com/releases/2026/05/260515002146.htm https://www.sciencedaily.com/releases/2026/05/260515002126.htm You may not need hours at the gym to boost your health after all. Researchers say just 30 minutes of high-intensity exercise per week — broken into tiny bursts of effort that leave you out of breath — can dramatically improve cardiovascular fitness, lower the risk of dozens of diseases, and even help protect the brain as we age. The key isn’t how long you exercise, but how hard you push yourself. Fri, 15 May 2026 20:20:30 EDT https://www.sciencedaily.com/releases/2026/05/260515002126.htm https://www.sciencedaily.com/releases/2026/05/260515000947.htm A groundbreaking Swedish study that tracked people for nearly 50 years has revealed when the body’s physical decline quietly begins. Researchers found that fitness, strength, and muscle endurance start slipping around age 35, with the decline accelerating over time. But there’s an encouraging twist: adults who became active later in life still improved their physical performance by up to 10 percent. Fri, 15 May 2026 00:15:26 EDT https://www.sciencedaily.com/releases/2026/05/260515000947.htm https://www.sciencedaily.com/releases/2026/05/260513221759.htm Scientists have finally cracked the mystery behind one of climate change’s strangest fingerprints: while Earth’s surface heats up, the upper atmosphere is rapidly cooling. Researchers at Columbia University discovered that carbon dioxide acts very differently high above the planet, where it actually helps radiate heat into space instead of trapping it. The team found that certain infrared wavelengths fall into a “Goldilocks zone” that becomes increasingly effective as CO2 levels rise, accelerating cooling in the stratosphere. Thu, 14 May 2026 03:24:00 EDT https://www.sciencedaily.com/releases/2026/05/260513221759.htm https://www.sciencedaily.com/releases/2026/05/260512202350.htm A huge long-term study found that drinking two to three cups of coffee a day was linked to a much lower risk of dementia, especially before age 75. Researchers say caffeine may help keep brain cells active while reducing inflammation and harmful plaque buildup associated with Alzheimer’s disease. But more coffee wasn’t better — the protective effect appeared to level off after moderate intake. Tue, 12 May 2026 20:23:50 EDT https://www.sciencedaily.com/releases/2026/05/260512202350.htm https://www.sciencedaily.com/releases/2026/05/260512202345.htm A daily multivitamin may help slow biological aging, according to researchers studying older adults in a large clinical trial. After two years, participants taking multivitamins showed slower aging in several DNA-based “epigenetic clocks,” with the effect equal to about four months less biological aging. People who started out biologically older than their actual age appeared to benefit the most. The findings hint that a simple supplement could play a role in healthier aging. Thu, 14 May 2026 10:22:46 EDT https://www.sciencedaily.com/releases/2026/05/260512202345.htm https://www.sciencedaily.com/releases/2026/05/260512202325.htm UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause hallucination-like behavior in animal tests. Scientists say the discovery could lead to future treatments for depression, PTSD, and addiction without the intense psychedelic experience. Wed, 13 May 2026 21:07:03 EDT https://www.sciencedaily.com/releases/2026/05/260512202325.htm https://www.sciencedaily.com/releases/2026/05/260511213144.htm A four-week diet change was enough to make some older adults appear biologically younger in a new University of Sydney study. Participants who reduced fat intake or shifted toward more plant-based protein showed improvements in key health biomarkers tied to aging. The strongest results came from a lower-fat, higher-carb diet, while people eating closer to their usual diets saw almost no change. Tue, 12 May 2026 08:44:25 EDT https://www.sciencedaily.com/releases/2026/05/260511213144.htm https://www.sciencedaily.com/releases/2026/05/260511213141.htm Scientists at McGill University have uncovered a hidden molecular “switch” that turns on a powerful calorie-burning system in brown fat — the body’s heat-generating fat linked to metabolism and weight control. The breakthrough centers on glycerol, a molecule released when fat is broken down in the cold, which activates an enzyme called TNAP and triggers an alternative heat-producing pathway that scientists had struggled to explain for years. Tue, 12 May 2026 07:58:13 EDT https://www.sciencedaily.com/releases/2026/05/260511213141.htm https://www.sciencedaily.com/releases/2026/05/260510234724.htm An ancient Chinese exercise routine may be just as powerful as a daily brisk walk for lowering blood pressure — without equipment, gyms, or intense workouts. In a major clinical trial, adults with stage 1 hypertension who practiced baduanjin, a gentle mind-body exercise combining slow movements, breathing, and meditation, saw meaningful drops in blood pressure within three months that lasted for an entire year. Sun, 10 May 2026 23:47:24 EDT https://www.sciencedaily.com/releases/2026/05/260510234724.htm https://www.sciencedaily.com/releases/2026/05/260510234722.htm Staying strong may be one of the biggest secrets to living longer — especially for older women. A major study of more than 5,000 women found that simple signs of muscle strength, like a firm hand grip or the ability to quickly stand up from a chair, were strongly linked to lower risk of death over the next eight years. Mon, 11 May 2026 21:13:48 EDT https://www.sciencedaily.com/releases/2026/05/260510234722.htm https://www.sciencedaily.com/releases/2026/05/260510234655.htm A new international analysis suggests there may be a surprisingly simple secret to keeping weight off after dieting: walking about 8,500 steps a day. Researchers found that people who boosted their daily steps to around that level during a weight-loss program — and kept it up afterward — were far more successful at avoiding the frustrating cycle of regaining lost weight. The study highlights a major challenge in obesity treatment, since most people regain much of the weight they lose within a few years. Sun, 10 May 2026 23:46:55 EDT https://www.sciencedaily.com/releases/2026/05/260510234655.htm https://www.sciencedaily.com/releases/2026/05/260510234654.htm A major new analysis suggests semaglutide (Ozempic, Wegovy) works remarkably well in adults over 65, helping many lose substantial amounts of weight while improving heart and metabolic health. Participants taking the drug lost over 15% of their body weight on average — far more than those receiving placebo treatment. Many also moved out of obesity categories entirely and reached healthier weight levels. Mon, 11 May 2026 00:57:51 EDT https://www.sciencedaily.com/releases/2026/05/260510234654.htm https://www.sciencedaily.com/releases/2026/05/260510030948.htm Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer. The special gene boosts production of a substance called high molecular weight hyaluronic acid, which appears to protect against cancer, reduce inflammation, and support healthier aging. The modified mice showed stronger resistance to tumors, healthier guts, and lower levels of age-related inflammation. Sun, 10 May 2026 07:27:12 EDT https://www.sciencedaily.com/releases/2026/05/260510030948.htm https://www.sciencedaily.com/releases/2026/05/260509210644.htm Ultra-processed foods may be doing far more damage than many people realize. A major new European cardiology report warns that people who eat the most ultra-processed foods face significantly higher risks of heart disease, irregular heart rhythms, obesity, diabetes, high blood pressure, and even cardiovascular death. Researchers say these industrially manufactured foods — often packed with sugar, salt, unhealthy fats, and additives — can disrupt metabolism, trigger inflammation, and promote overeating, even when marketed as “healthy.” Sun, 10 May 2026 20:59:36 EDT https://www.sciencedaily.com/releases/2026/05/260509210644.htm https://www.sciencedaily.com/releases/2026/05/260509210643.htm Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation, reduced DNA damage, and no signs of liver cancer. Researchers also found that the treatment suppressed a cancer-linked gene called MDM2, making older mice biologically resemble younger ones. Sat, 09 May 2026 22:58:28 EDT https://www.sciencedaily.com/releases/2026/05/260509210643.htm https://www.sciencedaily.com/releases/2026/05/260508003121.htm Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in salamanders and mice. They then used a gene therapy inspired by zebrafish biology to partially restore regeneration in mice, marking a major step toward future treatments that could replace damaged limbs with living tissue instead of prosthetics. Sat, 09 May 2026 01:04:19 EDT https://www.sciencedaily.com/releases/2026/05/260508003121.htm https://www.sciencedaily.com/releases/2026/05/260506225551.htm Many cancer patients turn to biotin supplements hoping to restore hair lost during treatment, but experts warn the popular vitamin may do more harm than good. While biotin is often marketed for stronger hair and nails, there’s little evidence it actually helps cancer-related hair loss—and it can dangerously interfere with lab tests. Doctors say the supplement can distort key blood markers, potentially masking cancer recurrence or delaying treatment decisions. Thu, 07 May 2026 22:07:42 EDT https://www.sciencedaily.com/releases/2026/05/260506225551.htm https://www.sciencedaily.com/releases/2026/05/260506225428.htm Researchers have created a next-generation obesity drug that works like a “Trojan horse,” using GLP-1/GIP signals to slip a powerful metabolic enhancer directly into target cells. In mice, it outperformed existing treatments—curbing appetite, increasing weight loss, and improving blood sugar levels. Because the extra drug acts only where it’s needed, it can be used at much lower doses, potentially reducing side effects. Thu, 07 May 2026 06:37:46 EDT https://www.sciencedaily.com/releases/2026/05/260506225428.htm https://www.sciencedaily.com/releases/2026/05/260506225235.htm Aging doesn’t just add fat—it redistributes it in risky ways, pushing more into the abdomen where it can harm health. Scientists found that testosterone plays a key role in this shift. In older women recovering from hip fractures, a testosterone gel combined with exercise helped prevent the usual rise in dangerous visceral fat. The result could point to a powerful new strategy for improving recovery and long-term health. Thu, 07 May 2026 05:25:59 EDT https://www.sciencedaily.com/releases/2026/05/260506225235.htm https://www.sciencedaily.com/releases/2026/05/260506225233.htm Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place. A year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight and improve blood sugar levels on GLP-1 medications. But people who eat mainly in response to stress, sadness, or emotional struggles didn’t see the same long-term benefits. Thu, 07 May 2026 06:11:48 EDT https://www.sciencedaily.com/releases/2026/05/260506225233.htm https://www.sciencedaily.com/releases/2026/05/260506225214.htm Eating eggs might do more than just start your day—it could help protect your brain. Researchers found that people 65 and older who eat eggs regularly have a significantly lower risk of developing Alzheimer’s disease, with daily or near-daily consumption linked to up to a 27% reduction. Even modest egg intake showed benefits, suggesting that small dietary changes could make a meaningful difference over time.

By viewing tourism through the lens of entropy, researchers found that positive travel experiences may help the body stay balanced and resilient. Activities like exploring new places, staying active, and connecting with others can boost immunity, metabolism, and stress recovery. However, stressful or unsafe travel could reverse these benefits. Mon, 04 May 2026 22:42:07 EDT https://www.sciencedaily.com/releases/2026/05/260504211836.htm https://www.sciencedaily.com/releases/2026/05/260504154016.htm GLP-1 weight-loss drugs like Ozempic and Wegovy are often celebrated as game-changing solutions—but new research reveals a surprising social twist. People who lose weight using these medications may actually face more judgment than those who lose weight through diet and exercise—or even those who don’t lose weight at all. The stigma seems rooted in a perception that these drugs are an “easy way out,” creating a double bind where individuals are judged both for their weight and for how they choose to manage it. Tue, 05 May 2026 14:04:18 EDT https://www.sciencedaily.com/releases/2026/05/260504154016.htm https://www.sciencedaily.com/releases/2026/05/260504075512.htm A new study suggests a surprisingly simple compound could help fight Alzheimer’s disease. Researchers found that arginine—an inexpensive amino acid already considered safe—can reduce the buildup of toxic amyloid proteins in the brain, a hallmark of the disease. In animal models, oral arginine not only lowered harmful protein deposits but also improved behavior and reduced brain inflammation.

Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and cognitive symptoms of depression, like hopelessness and loss of pleasure, rather than physical symptoms such as fatigue. Mon, 04 May 2026 03:17:17 EDT https://www.sciencedaily.com/releases/2026/05/260504023827.htm https://www.sciencedaily.com/releases/2026/05/260502233924.htm GLP-1 drugs like semaglutide—best known for treating diabetes and driving weight loss under the brand names Ozempic and Wegovy—may also deliver a surprising mental health boost. In a massive study tracking nearly 100,000 people over more than a decade, researchers found that these medications were linked to significantly fewer psychiatric hospital visits and sick days. Mon, 04 May 2026 02:14:05 EDT https://www.sciencedaily.com/releases/2026/05/260502233924.htm https://www.sciencedaily.com/releases/2026/05/260502233911.htm Coffee doesn’t just energize—it actively reshapes the gut and mind. Researchers found that both caffeinated and decaf coffee altered gut bacteria in ways linked to better mood and lower stress. Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety. Together, they show coffee works through multiple pathways beyond just caffeine. Sun, 03 May 2026 12:18:40 EDT https://www.sciencedaily.com/releases/2026/05/260502233911.htm https://www.sciencedaily.com/releases/2026/05/260501052832.htm Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your skull. This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially flushing out harmful waste. Fri, 01 May 2026 23:04:01 EDT https://www.sciencedaily.com/releases/2026/05/260501052832.htm https://www.sciencedaily.com/releases/2026/05/260501052830.htm Building muscle doesn’t have to mean exhausting workouts or soreness. Researchers found that slow, controlled “lowering” movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like chair squats or wall push-ups can make a real difference. It’s a smarter, easier way to get stronger—no gym required. Fri, 01 May 2026 10:07:35 EDT https://www.sciencedaily.com/releases/2026/05/260501052830.htm https://www.sciencedaily.com/releases/2026/05/260501013525.htm A new breakthrough could change how high cholesterol is treated, offering a powerful alternative to traditional drugs. Researchers have developed tiny DNA-based molecules that shut down PCSK9—a key protein that keeps “bad” LDL cholesterol circulating in the blood. By blocking this protein, cells can absorb more cholesterol instead of letting it build up in arteries, dramatically lowering levels linked to heart disease.

Instead of just releasing fat, it helps maintain healthy fat tissue and balance in the body. When it’s missing or disrupted, the results can be surprisingly harmful. This finding reshapes how researchers think about obesity and metabolic disease.

Activities like walking, cycling, and swimming outperformed other exercise types in reducing pain and improving movement. While alternatives like strength training and mind-body exercises help, they are best used alongside aerobic workouts. The findings also confirm that exercise is a safe and essential part of treatment.

Scientists analyzing thousands of people found that those under high stress who also ate a large portion of their calories after 9 p.m. were far more likely to suffer from constipation and diarrhea. The combination appears to hit the gut twice, not only disrupting digestion but also reducing the diversity of beneficial gut bacteria.

In a small study, women who took low doses alongside treatment were far more likely to see their cancer vanish than those who didn’t. Since vitamin D also supports immune function—and many patients are deficient—it could be playing a bigger role than expected. Scientists say this affordable approach deserves much deeper investigation.

Surprisingly, factors like community support didn’t show the same impact. Researchers say cultural pressures and stereotypes may cause emotional struggles to go unnoticed and untreated. The findings suggest that targeted, culturally sensitive stress relief could play a powerful role in preserving cognitive health.

Researchers found that a small, little-known region called the caudal granular insular cortex (CGIC) acts like a command center, telling the body to keep pain signals alive long after an injury has healed. In animal studies, shutting down this pathway not only prevented chronic pain from forming but could even erase it once it had taken hold.

Long-term research tracking over 100,000 people for more than three decades suggests that doing a variety of physical activities—rather than just more of the same—can significantly lower the risk of death. Interestingly, the benefits don’t keep rising endlessly; they seem to level off after a certain point, hinting at a “sweet spot” of activity.

Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline.

Researchers found that when Morganella morganii interacts with a common pollutant, it produces a molecule that triggers inflammation—something strongly linked to depression. This finding helps explain how gut microbes can influence brain health at a molecular level. It also raises the possibility of new treatments that target the immune system rather than just the brain.

By targeting a molecule found only in bacterial membranes, this ultra-thin carbon-based material acts with laser-like precision—offering a powerful new alternative to traditional antibiotics. Even more exciting, it works against drug-resistant “superbugs,” promotes faster wound healing, and keeps its antibacterial strength even after repeated washing.

A new study reveals that one of the biggest obstacles—cracking during ultra-cold preservation—can be reduced by carefully tuning the temperature at which tissues enter a glass-like state. This breakthrough builds on recent successes in cryopreserved organ transplants and could bring the long-imagined idea of “banking” organs for later use much closer to reality.

With memory abilities comparable to people decades younger, their brains either resist or withstand the damage typically linked to Alzheimer’s disease. Decades of research reveal that their social lifestyles and unique brain biology may hold the key to preserving cognitive function. Scientists believe these insights could pave the way for new strategies to delay or even prevent dementia.

In a clinical trial, those who underwent a technique called duodenal mucosal resurfacing regained far less weight compared to others after discontinuing the medication. The procedure works by renewing the lining of the upper small intestine, potentially “resetting” metabolism and preserving the benefits of weight loss.
