We've all heard that making simple lifestyle changes today can help prevent heart disease down the line. But what if you already have key risk factors for heart disease, or even a diagnosis of heart disease ...

Adult survivors of childhood cancers are at higher risk for another cancer—such as breast, colorectal, sarcomas and thyroid cancer—that is not a relapse of their original illness. Previous cancer ...

Recent global crises have exposed the limits of a universal mortality threshold for declaring famine—an approach that can obscure how famine actually unfolds across different populations. In a paper ...

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…

Scientists are launching an ambitious global effort to map the “human exposome” — the lifelong mix of environmental and chemical exposures that drive most diseases. Backed by new partnerships with governments, UNESCO, and international science advisory bodies…

Scientists at Michigan State University have uncovered the molecular “switch” that powers sperm for their final, high-speed dash toward an egg. By tracking how sperm use glucose as fuel, the team discovered how dormant cells suddenly flip into overdrive,…

A new study shows that dogs and cats may be helping an invasive flatworm spread. Researchers analyzing over a decade of reports discovered the worm attached to pet fur. Its sticky mucus and ability to reproduce alone make it highly adaptable. Pets could be…

Couples who intentionally slow down and soak in their happy moments together may be building a powerful shield for their relationship. Researchers at the University of Illinois found that partners who regularly savor shared experiences—whether reminiscing…

WHO is aware of the proposed randomized controlled trial (RCT) on the hepatitis B birth dose vaccine in Guinea-Bissau. Based on questions raised in publicly available information and consultation with relevant experts, WHO has significant concerns regarding…

In the rapidly disappearing Atlantic Forest, mosquitoes are adapting to a human-dominated landscape. Scientists found that many species now prefer feeding on people rather than the forest’s diverse wildlife. This behavior dramatically raises the risk of spreading…

A massive review of 23 randomized trials found that statins do not cause the vast majority of side effects listed on their labels. Memory problems, depression, sleep issues, weight gain, and many other symptoms appeared just as often in people taking a placebo.…

Sleeping on a problem might be more powerful than we ever imagined. Neuroscientists at Northwestern University have shown that dreams can actually be nudged in specific directions — and those dream tweaks may boost creativity. By playing subtle sound cues…

Psychedelics can quiet the brain’s visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal recall —…

Spikes in blood sugar after eating may be more dangerous for the brain than previously thought. In a massive genetic study, people with higher post-meal blood sugar had a much greater risk of Alzheimer’s disease. The effect couldn’t be explained by visible…

New research suggests statins may protect adults with type 2 diabetes regardless of how low their predicted heart risk appears. In a large UK study, statin use was linked to fewer deaths and major cardiac events across all risk levels. Even those labeled…

Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between genes across…

A simple shift in your evening routine may give your heart a measurable boost. In a new study, adults who stopped eating and dimmed the lights three hours before bed and extended their overnight fast by about two hours saw improvements in blood pressure,…

Scientists have uncovered a hidden partnership between pancreatic cancer and the nervous system. Support cells in the pancreas lure nerve fibers, which then release signals that accelerate early cancer growth. This creates a self-sustaining loop that helps…

A major new study suggests that eating the Nordic way could help you live significantly longer—while also helping the planet. Researchers from Aarhus University found that people who closely followed the 2023 Nordic dietary guidelines had a 23% lower risk…

A new Stanford study suggests math struggles may be about more than numbers. Children who had difficulty with math were less likely to adjust their thinking after making mistakes during number comparison tasks. Brain imaging showed weaker activity in regions…
