Vitamins like B12 and D can play an important role when levels are low, while protein may be one of the most overlooked nutrients for maintaining strength and independence. More isn’t always better, though—some supplements can cause harm or interact with medications. Sat, 06 Jun 2026 08:40:28 EDT https://www.sciencedaily.com/releases/2026/06/260605023408.htm https://www.sciencedaily.com/releases/2026/06/260605023400.htm A large study found that women taking GLP-1 drugs, the medication class behind Ozempic, Wegovy, Mounjaro, and Zepbound, were about 30% less likely to develop breast cancer. Researchers say the findings are promising but not yet proof, and clinical trials are now being planned to test whether these drugs could help prevent breast cancer.

Researchers also found modest benefits for muscle and tendon health. But the results challenge claims that collagen enhances sports performance, as it showed little effect on recovery or post-workout soreness. Fri, 05 Jun 2026 01:13:11 EDT https://www.sciencedaily.com/releases/2026/06/260604044302.htm https://www.sciencedaily.com/releases/2026/06/260604044247.htm For decades, pancreatic cancer has been one of the most lethal cancers, with few effective treatment options. A new drug, daraxonrasib, targets the KRAS mutation that fuels most pancreatic tumors—something many scientists once thought couldn't be done. In a major clinical trial, the treatment nearly doubled survival for patients with advanced disease and reduced the risk of death by 60%. Thu, 04 Jun 2026 09:18:44 EDT https://www.sciencedaily.com/releases/2026/06/260604044247.htm https://www.sciencedaily.com/releases/2026/06/260602021634.htm Scientists have uncovered evidence that autism may include at least two biologically distinct subtypes, each marked by a different pattern of brain communication. By combining brain scans from nearly 1,000 people with autism with insights from 20 genetically engineered mouse models, researchers identified a “hyperconnectivity” subtype, where brain regions communicate more than usual, and a “hypoconnectivity” subtype, where communication is reduced. Wed, 03 Jun 2026 00:46:00 EDT https://www.sciencedaily.com/releases/2026/06/260602021634.htm https://www.sciencedaily.com/releases/2026/06/260601025352.htm A long-overlooked organ may hold surprising clues to healthy aging and cancer survival. Researchers at Mass General Brigham used AI to analyze CT scans from tens of thousands of adults and found that people with healthier thymuses—a small immune-system organ once thought to become largely irrelevant after childhood—lived longer and had substantially lower risks of heart disease, cancer, and death. Mon, 01 Jun 2026 06:17:04 EDT https://www.sciencedaily.com/releases/2026/06/260601025352.htm https://www.sciencedaily.com/releases/2026/05/260530004622.htm Losing weight may involve rewiring the gut and the brain at the same time. In a study of obese adults, an intermittent fasting-style diet led to significant weight loss, healthier metabolic markers, and notable shifts in gut bacteria. Brain scans also revealed changes in regions tied to appetite, cravings, and self-control. The results suggest the gut microbiome and brain may work together to influence weight-loss success. Sun, 31 May 2026 05:01:44 EDT https://www.sciencedaily.com/releases/2026/05/260530004622.htm https://www.sciencedaily.com/releases/2026/05/260529030324.htm A sweeping global study found that chronic kidney disease now affects nearly 800 million people and has become one of the world's leading causes of death. Often silent in its early stages, the condition is also a major contributor to heart disease and may be even more common than current estimates suggest. Fri, 29 May 2026 07:10:34 EDT https://www.sciencedaily.com/releases/2026/05/260529030324.htm https://www.sciencedaily.com/releases/2026/05/260528082507.htm CBD may be doing far more than just easing pain or anxiety — new research suggests it could help fight Alzheimer’s disease by calming the brain’s runaway immune response. In experiments using Alzheimer’s mice, scientists found that inhaled CBD reduced key drivers of neuroinflammation, a damaging process increasingly linked to memory loss and brain degeneration. Thu, 28 May 2026 21:35:52 EDT https://www.sciencedaily.com/releases/2026/05/260528082507.htm https://www.sciencedaily.com/releases/2026/05/260528082459.htm Cambridge researchers created miniature brain-and-spinal-cord systems in the lab that can send signals and even trigger tiny muscle contractions. They discovered that human neurons gradually lose their ability to regrow after damage during development — but that ability can potentially be switched back on. The team identified a gene network controlling this process and found that an existing hormone drug dramatically boosted nerve fiber regrowth. Thu, 28 May 2026 22:55:05 EDT https://www.sciencedaily.com/releases/2026/05/260528082459.htm https://www.sciencedaily.com/releases/2026/05/260528074032.htm Researchers are developing a futuristic alternative to LASIK that reshapes the eye without lasers or incisions. Using mild electrical pulses and platinum contact lenses, they temporarily soften the cornea so it can be molded into a new shape. Early tests on rabbit eyes successfully corrected nearsightedness in about a minute while preserving the eye’s structure.

Researchers at Aalto University discovered a way to gently heat tissue at the back of the eye using near-infrared light, triggering the cells’ natural “cleanup and repair” systems before major damage occurs. Wed, 27 May 2026 07:43:10 EDT https://www.sciencedaily.com/releases/2026/05/260526233217.htm https://www.sciencedaily.com/releases/2026/05/260526022018.htm Researchers at Texas A&M have developed a nasal spray that appears to reverse brain aging by calming inflammation and restoring the brain’s energy systems. After just two doses, memory and cognitive function improved for months, raising hopes for future treatments targeting dementia and brain fog. Tue, 26 May 2026 09:39:35 EDT https://www.sciencedaily.com/releases/2026/05/260526022018.htm https://www.sciencedaily.com/releases/2026/05/260524021154.htm Drinking nitrate-rich beetroot juice may do more than support heart health — it could actually reshape the bacteria living in the mouth in ways that help lower blood pressure in older adults. In the largest study of its kind, researchers found that older people who drank concentrated beetroot juice twice daily for two weeks experienced noticeable blood pressure reductions, while younger adults did not. Mon, 25 May 2026 01:01:09 EDT https://www.sciencedaily.com/releases/2026/05/260524021154.htm https://www.sciencedaily.com/releases/2026/05/260524021151.htm A massive international study could upend 40 years of heart attack treatment. Researchers found that beta blockers—routinely prescribed after uncomplicated heart attacks—offered no real benefit for patients whose heart function remained normal, despite being given to millions worldwide. Even more surprising, women taking the drugs faced a higher risk of death, repeat heart attack, or hospitalization for heart failure compared to women who didn’t receive them.

In a year-long clinical trial, researchers found that slightly changing the angle of a person’s foot while walking reduced knee pain as effectively as common medications — and even slowed cartilage damage inside the joint. Fri, 22 May 2026 07:07:58 EDT https://www.sciencedaily.com/releases/2026/05/260522031135.htm https://www.sciencedaily.com/releases/2026/05/260522031001.htm Getting enough vitamin B12 to meet current health guidelines may not actually be enough to protect the aging brain. Researchers at UC San Francisco found that older adults with “normal” but lower levels of active B12 showed signs of slower thinking, delayed visual processing, and more damage to the brain’s white matter — the communication highways that help different brain regions work together.

The discovery is fueling a new wave of precision anti-aging therapies aimed at removing only the harmful “zombie” cells without disrupting the body’s natural repair systems. Fri, 22 May 2026 00:28:12 EDT https://www.sciencedaily.com/releases/2026/05/260521072402.htm https://www.sciencedaily.com/releases/2026/05/260520233223.htm MIT scientists have identified cysteine — an amino acid found in foods like meat, dairy, beans, and nuts — as a potent trigger for intestinal repair. In mice, a cysteine-rich diet activated immune cells that released healing signals, helping stem cells rebuild damaged intestinal tissue after radiation exposure. Researchers say the discovery could eventually lead to new dietary therapies for cancer patients suffering from treatment-related gut damage.

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.

A major Swiss study analyzing nearly 100,000 cases over four decades found that diagnoses in people under 50 have been steadily climbing, even as rates fall among older adults thanks to screening programs. Researchers say younger patients are also more likely to be diagnosed late, after the cancer has already spread.

A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the nucleus of fat cells—helping keep those cells healthy and balanced. Even more surprising, people and mice missing this protein don’t become obese as expected; instead, they lose fat tissue in a dangerous condition called lipodystrophy.

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.

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.

Patients in a UK-led trial who received just nine weeks of pembrolizumab prior to surgery have remained cancer-free nearly three years later—an outcome that challenges the standard approach of surgery followed by months of chemotherapy.

Researchers found that trimming a damaged meniscus—a procedure long believed to relieve pain—offers no real benefit over placebo surgery. Even more surprising, patients who had the operation actually fared worse over time, with more symptoms, poorer function, faster progression of osteoarthritis, and a greater likelihood of needing additional surgery.

In animal studies, it successfully treated heart attack damage and even showed promise for conditions like traumatic brain injury and pulmonary hypertension. Unlike earlier approaches that required direct injection into the heart, this new therapy can be delivered intravenously, allowing it to spread evenly and act quickly.

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.

Even more concerning, they may increase the risk of brain swelling and bleeding, sometimes without obvious symptoms.

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.

In experiments with mice, young animals exposed to the chemical developed significantly more DNA damage and cancer, despite experiencing the same initial exposure as adults. The key difference lies in how rapidly children’s cells divide, which turns early DNA damage into dangerous mutations much more easily.

This “pencil beam” enabled them to image the blood-brain barrier in 3D at speeds 25 times faster than existing techniques. The method also lets researchers watch how drugs move into brain cells in real time. It could dramatically accelerate the development of treatments for neurological diseases.

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.

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.

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.
