Exercise normally boosts the body’s ability to use oxygen, a key marker of health and longevity — but high blood sugar can block that benefit. Researchers found that a ketogenic diet helped mice normalize blood sugar and dramatically improved how their muscles…

Pre-workout supplements promising extra energy for workouts may come with a hidden cost: severely reduced sleep. A study of people aged 16–30 found users were more than twice as likely to sleep five hours or less per night. Many of these products pack huge…

DNA is revealing that many animals once thought to be a single species may actually be several hidden ones. But research on Bornean fanged frogs shows the line between species can be blurry—an important challenge when deciding what wildlife needs protection…

Plants constantly juggle oxygen inside their cells, but scientists have now discovered a surprising twist in how that balance works. Researchers at the University of Helsinki found that mitochondria—the cell’s energy generators—can actively pull oxygen away…

Up to four in ten cancer cases worldwide could be prevented, according to a new global analysis from the World Health Organization (WHO) and its International Agency for Research on Cancer (IARC). The study examines 30 preventable causes, including tobacco…

Researchers have found hundreds of metabolic enzymes attached to human DNA inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic fingerprint.” Some of the enzymes gather around damaged DNA…

Researchers have created a method called optovolution that uses light to guide the evolution of proteins with dynamic behaviors. By engineering yeast cells so their survival depended on proteins switching states at the right time, scientists could rapidly…

Sound machines may not be the sleep saviors many believe. Researchers found that pink noise significantly reduced REM sleep, while simple earplugs did a better job protecting deep, restorative sleep from traffic noise. When pink noise was combined with outside…

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while preserving fat-related ones. This process, driven by ER-phagy…

A nearly complete dinosaur skeleton discovered in Patagonia is helping scientists crack the mystery of alvarezsaurs, a bizarre group of bird-like dinosaurs. The fossil of Alnashetri cerropoliciensis reveals that these animals became tiny before developing…

Colorblindness may be doing more than making traffic lights confusing — it could also be hiding a life-threatening warning sign. Researchers analyzing millions of medical records found that people with bladder cancer who are also colorblind have a 52% higher…

Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome separation during cell division. By studying related yeast species, researchers found centromeres that appear to represent evolutionary…

A new analysis of more than 422,000 patients reveals a stark Alzheimer’s care gap between Maryland’s urban and rural communities. Rural regions often lack hospitals and dementia specialists, forcing older patients to travel farther for diagnosis and treatment.…
