Statins are a cornerstone of heart health, but muscle pain and weakness cause many patients to quit taking them. Scientists have now identified the precise molecular trigger behind these side effects. They found that statins jam open a critical muscle protein, causing a toxic calcium leak. The discovery could lead to safer statins that keep their life-saving benefits without the muscle damage.

A quiet change in everyday foods could save thousands of lives
Lowering salt in everyday foods could quietly save lives. Researchers found that modest sodium reductions in bread, packaged foods, and takeout meals could significantly reduce heart disease and stroke rates in France and the U.K. The key advantage is that people would not need to alter their eating habits at all. Small changes to the food supply could deliver large, long-term health benefits.

A fish that ages in months reveals how kidneys grow old
A fast-aging fish is giving scientists a rare, accelerated look at how kidneys grow old—and how a common drug may slow that process down. Researchers found that SGLT2 inhibitors, widely used to treat diabetes and heart disease, preserved kidney structure, blood vessels, and energy production as the fish aged, while also calming inflammation. The results help explain why these drugs protect kidneys and hearts so reliably in people, even beyond blood sugar control.

Brain cancer may begin years before doctors can see it
Scientists in South Korea have discovered that one of the most common malignant brain tumors in young adults may begin years before a tumor can be seen. IDH-mutant glioma, long treated by removing visible tumor tissue, actually starts when normal-looking brain cells quietly acquire a cancer-linked mutation and spread through the brain’s cortex. Using advanced genetic mapping and animal models, researchers traced the cancer’s true origin to glial progenitor cells that appear healthy at first.

Why long COVID brain fog seems so much worse in the U.S.
A massive international study of more than 3,100 long COVID patients uncovered a striking divide in how brain-related symptoms are reported around the world. In the U.S., the vast majority of non-hospitalized patients described brain fog, depression, and anxiety, while far fewer patients in countries like India and Nigeria reported the same issues. The difference doesn’t appear to be about the virus itself, but about culture, stigma, and access to mental health care.

The fat you can’t see could be shrinking your brain
Where your body stores fat may matter just as much as how much you carry—especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive decline, and higher neurological disease risk. One involves unusually high fat buildup in the pancreas, even without much liver fat, while the other—often called “skinny fat”—affects people who don’t appear severely obese but carry excess fat relative to muscle.

Asthma may not be driven by the molecules scientists have blamed for decades.

A protein once thought to simply help cancer cells avoid death turns out to do much more. MCL1 actively drives cancer metabolism by controlling the powerful mTOR growth pathway, tying survival and energy use together. This insight explains why MCL1-targeting drugs can be effective—but also why they sometimes damage the heart. Researchers have now identified a way to reduce that risk, potentially unlocking safer cancer therapies.

Scientists find a safer way to make cells burn more calories
Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria produce energy. Older versions of these chemicals were once used for weight loss—but were banned for being deadly. The new approach fine-tunes the effect, allowing cells to burn extra fuel safely. If successful, this could pave the way for new obesity treatments with added health benefits.

Why warm hugs feel so good to your brain
Feeling warm or cold doesn’t just register on the skin—it changes how connected we feel to our own bodies. Research shows that temperature sensations help shape body ownership, emotional regulation, and mental well-being. Disruptions in thermal perception are linked to conditions like depression, trauma, and stroke-related body disconnect. These insights could lead to new sensory-based mental health treatments and more lifelike prosthetics.

The invisible microbes that help keep us healthy
Not all microbes are villains—many are vital to keeping us healthy. Researchers have created a world-first database that tracks beneficial bacteria and natural compounds linked to immune strength, stress reduction, and resilience. The findings challenge the long-standing obsession with germs as threats and instead highlight the hidden health benefits of biodiversity. This shift could influence everything from urban design to environmental restoration.

Menopause symptoms are common even in elite endurance athletes
Menopause symptoms are common among female endurance athletes and often interfere with training and performance. A survey of women aged 40–60 who train regularly found high rates of sleep problems, exhaustion, anxiety, weight gain, and joint pain. Many athletes said these symptoms made it harder to train effectively or perform at their best. The results highlight a need for greater attention to menopause in active women.

A "herculean" genetic study just found a new way to treat ADHD
Attention depends on the brain’s ability to filter out distractions, but new research suggests this works best when background brain activity is quieter. Scientists found that lowering certain versions of the Homer1 gene improved focus in mice by calming neural noise. The effect was strongest during a critical developmental window. This approach could inspire new treatments for ADHD that work by reducing mental clutter instead of increasing stimulation.

This tiny nerve may help keep the heart young
A new study suggests the vagus nerve may be one of the heart’s most important defenders against aging. Researchers found that keeping this nerve connected to the heart helps protect heart cells and maintain strong pumping ability. Even partial restoration of the nerve was enough to slow harmful changes in heart tissue. The discovery could reshape future heart and transplant surgeries.

A key Alzheimer’s gene emerges in African American brain study
Scientists studying Alzheimer’s in African Americans have uncovered a striking genetic clue that may cut across racial lines. In brain tissue from more than 200 donors, the gene ADAMTS2 was significantly more active in people with Alzheimer’s than in those without it. Even more surprising, this same gene topped the list in an independent study of White individuals. The discovery hints at a common biological pathway behind Alzheimer’s and opens the door to new treatment strategies.

This 100-year-old teaching method is beating modern preschools
A first-of-its-kind national trial shows that public Montessori preschool students enter kindergarten with stronger reading, memory, and executive function skills than their peers. These gains don’t fade — they grow over time, bucking a long-standing trend in early education research. Even better, Montessori programs cost about $13,000 less per child than traditional preschool. The results suggest a powerful, affordable model hiding in plain sight.
