- newScientists used brain stimulation to make people more generous
A new study suggests that generosity may be more than a moral lesson—it could be shaped by how different parts of the brain work together. By gently stimulating two brain regions and syncing their activity, researchers found that people became more willing to share money with others, even when it meant earning less themselves.

- newOmega-3 fish oil supplements could backfire without this key enzyme
Fish oil’s cancer-fighting reputation may hinge on a little-known gene. Researchers discovered that omega-3s like EPA and DHA help curb colorectal cancer only when the enzyme ALOX15 is present. Without it, fish oil sometimes increased tumor growth in mice—especially DHA. The results suggest that not all supplements work the same way, and genetics could determine who truly benefits.

- newScientists discover hidden brain cells that help heal spinal cord injuries
Scientists at Cedars-Sinai have uncovered a surprising repair system in the spinal cord that could open new doors for treating paralysis, stroke, and diseases like multiple sclerosis. They found that special support cells called astrocytes—located far from the actual injury—spring into action after damage. These “lesion-remote astrocytes” send out a protein signal, CCN1, that reprograms immune cells to efficiently clean up fatty nerve debris.

- newScientists make microplastics glow to see what they do inside your body
Microplastics and nanoplastics are now found everywhere on Earth, from ocean depths to agricultural soils and even inside the human body. Yet scientists still struggle to understand what these particles actually do once they enter living organisms. A new study proposes an innovative fluorescence-based strategy that could allow researchers to track microplastics in real time as they move, transform, and degrade inside biological systems.

- This vegan diet cut insulin use by nearly 30% in type 1 diabetes
A low-fat vegan diet—without cutting calories or carbs—may help people with type 1 diabetes significantly reduce how much insulin they need, and how much they spend on it. In a new analysis published in BMC Nutrition, participants following the plant-based plan lowered their daily insulin use by 28%, while those on a portion-controlled diet saw no meaningful change.

- The exact speed that makes an AI prosthetic arm feel like your own
A robotic arm that moves too quickly can feel creepy. One that moves too slowly feels awkward and unhelpful. In a VR study, researchers found that AI-powered prosthetic arms were best accepted when they moved at a natural, human-like speed—about one second per reach. That sweet spot boosted feelings of control, comfort, and even trust in the robot.

- Scientists discover hidden trigger behind achilles pain and tennis elbow
A protein called HIF1 may be the missing link behind painful tendon injuries like jumper’s knee and tennis elbow. Researchers showed that high levels of HIF1 actually cause harmful changes that make tendons brittle and prone to pain. In experiments, turning the protein off protected tendons — even under heavy strain.

- Scientists discover protein that rejuvenates aging brain cells
A newly identified protein may hold the key to rejuvenating aging brain cells. Researchers found that boosting DMTF1 can restore the ability of neural stem cells to regenerate, even when age-related damage has set in. Without it, these cells struggle to renew and support memory and learning. The findings raise hopes for treatments that could slow or even reverse aspects of brain aging.

- One simple daily change that could slash depression risk
Swapping just an hour of TV a day for something more active could significantly lower the risk of developing major depression—especially in middle age. A large Dutch study tracking more than 65,000 adults over four years found that replacing 60 minutes of TV with other activities cut depression risk by 11% overall, and by nearly 19% in middle-aged adults. The more time people reallocated—up to two hours—the greater the benefit, with risk dropping as much as 43% in midlife.

- This kefir and fiber combo beat omega-3 in slashing inflammation
A six-week study from the University of Nottingham suggests that pairing fermented kefir with a diverse prebiotic fiber mix may deliver a powerful anti-inflammatory boost. This “synbiotic” combination outperformed omega-3 supplements and fiber alone, leading to the broadest drop in inflammation-related proteins in healthy adults. By feeding beneficial microbes and helping them produce compounds like butyrate, the combo appeared to improve overall immune balance and metabolic health.

- Just 5 weeks of brain training may protect against dementia for 20 years
A simple brain-training program that sharpens how quickly older adults process visual information may have a surprisingly powerful long-term payoff. In a major 20-year study of adults 65 and older, those who completed five to six weeks of adaptive “speed of processing” training — along with a few booster sessions — were significantly less likely to develop dementia, including Alzheimer’s disease, even two decades later. Participants who received the boosted speed training had a 25% low…

- Changing when you eat dramatically reduced Crohn’s disease symptoms
A new clinical trial suggests that changing when you eat could make a meaningful difference for people living with Crohn’s disease. Researchers found that time-restricted feeding, a form of intermittent fasting that limits meals to an 8-hour daily window, reduced disease activity by 40% and cut abdominal discomfort in half over 12 weeks. Participants also lost weight and showed healthier inflammation and immune markers, even though they did not reduce calories or change what they ate.

- Blockbuster weight loss drugs like Ozempic deliver big results but face big questions
Three major reviews commissioned by the World Health Organization find that GLP-1 drugs including tirzepatide (sold as Mounjaro and Zepbound), semaglutide (Ozempic and Wegovy), and liraglutide (Victoza and Saxenda) can lead to substantial weight loss in people with obesity. But while the results are impressive, researchers caution that most trials were funded by drugmakers, long term safety data are still limited, and side effects such as nausea are common.

- Depression may be the brain’s early warning sign of Parkinson’s or dementia
Depression in older adults may sometimes signal the early stages of Parkinson’s disease or Lewy body dementia. Researchers found that depression often appears years before diagnosis and remains elevated long afterward, unlike in other chronic illnesses. This suggests depression may reflect early brain changes rather than emotional distress alone.

- This bedroom temperature could help older adults sleep with less stress
A cooler bedroom might be better for older sleepers than previously thought. Researchers found that keeping nighttime temperatures at 75°F reduced stress responses and helped the heart work more efficiently during sleep. Hot nights usually force the heart to work harder, interfering with recovery. As climate change drives warmer nights, this small adjustment could make a big difference.
