Certain lifestyle habits, like eating a nutritious diet, can lower dementia risk.Walnuts are rich in healthy fats, antioxidants and fiber, which may protect both your brain and heart.For a healthy brain, follow the MIND diet, stay physically active, sleep well and challenge your mind. Every three seconds, someone in the world is diagnosed with dementia, a condition marked by general decline in cognitive functioning. “Cognitive decline refers to a gradual loss of brain functions such as memory, attention, language, problem-solving and decision making. It ranges from mild changes that are a part of normal aging (like occasionally forgetting a name)…

Sleep is crucial for recovery, muscle growth, energy replenishment, and mental well-being.

Cells are poor storytellers. They live complex, eventful lives — dividing, migrating, responding to their environment. But by the time they reach the laboratory, whatever narrative they once carried is gone. Plucked from their native context and pinned beneath a microscope or cracked open to expose the genetic ledger inside, they reveal only their final state, not the path that led them there. For cell biologists, it’s like glimpsing a play’s finale and working backwards to deduce the plot.Molecular barcodes reveal tumour lineagesFor decades, researchers have strained to reconstruct cellular backstories through indirect means: static snapshots, fluorescent footprints and algorithmic…

The Great Holocene Transformation: What Complexity Science Tells Us about the Evolution of Complex Societies Peter Turchin Beresta Books (2025)When Spanish conquistador Hernán Cortés arrived in Mexico in 1519, he found monarchs, cities, roads, markets, schools, astronomers, law courts and much else that also existed in his native Spain. Put another way, two cultural experiments had been running in parallel for 15,000 years, and when they came into contact, each recognized the other’s institutions.It wasn’t just the civilizations of the Americas and Europe that resembled each other by that time. As biologist-turned-historian Peter Turchin observes in his tenth book, The…

For years, the health and fitness world has perpetuated the idea that “eating less and exercising more” is the holy grail for achieving a lean, strong physique. Abbie Smith-Ryan, Ph.D., a leading researcher in the field of metabolism, sports nutrition, and exercise performance, is here to tell you that this approach is outdated—and counterproductive.

A study headed by researchers at the Centre for Genomic Regulation (CRG) in Barcelona has provided for the first time evidence that a single drug, already licensed for medical use, can stabilize nearly all mutated versions of a human protein, regardless of where the mutation is in the sequence. The researchers, Taylor Mighell, PhD, a postdoctoral researcher at the Centre for Genomic Regulation (CRG) in Barcelona, and Ben Lehner, PhD, ICREA Research Professor, group leader at the Wellcome Sanger Institute and CRG, reported on their work in Nature Structural & Molecular Biology, in a paper titled “A small molecule stabilizer…

Scientists share who they thought will win the Nobel Prizes this year. Image credit:©iStock, Anton Skripachev​Every year in early October, scientists wonder whose phone will ring with a call from Sweden. This year, the Nobel Committee will announce the winners of the 2025 Nobel Prizes from October 6th to 13th. In anticipation of those reports, the editors at The Scientist asked researchers who they think might be honored this year.Who do you think will win a Nobel Prize this year?Claire Holt courtesy of The Rockefeller UniversityLi Zhao, evolutionary geneticist, The Rockefeller University There are so many deserving research contributions across diverse…

What happens when you don’t eat? Risks include nutrient gaps, poor digestion and higher disease risk.Skipping meals can trigger stress hormones, leaving you anxious, irritable and low on energy.Ignoring hunger cues may disrupt hormones that regulate appetite, leading to overeating later. Whether you’re joining in on the intermittent fasting trend, working through lunch or skipping breakfast, going too long between meals can have some serious consequences. Food helps to power every system in our bodies, so pretty much every part of your body is impacted when you skip a meal or fast. We asked Christy Harrison, M.P.H., RD, CDN and…

Breakfast is your first opportunity of the day to feed your body foods that’ll help fight inflammation. But, all too often, we pile our breakfast plates with stuff that can cause an inflammatory response.While short-term, acute inflammation is a helpful tool that triggers the body’s defenses to attack foreign invaders (like to fend off the common cold or heal a wound), chronic inflammation is a larger problem, says Leslie Langevin, RD, author of ‌The Anti-Inflammatory Kitchen Cookbook‌.Chronic inflammation happens when the immune system becomes overactive to protect itself from threats (which can result from an inflammatory diet, among other things),…
