Coenzyme A, a molecule derived from vitamin B5, is vital for metabolism throughout the body. Scientists discovered that most of it resides inside mitochondria, yet how it reached these cellular powerhouses was unclear. Yale researchers have now identified…

Scientists have developed a promising new approach to treating Alzheimer’s disease by turning ordinary brain cells into powerful plaque-clearing machines. Instead of requiring frequent antibody infusions like current therapies, the experimental treatment…

Scientists have discovered that a rare “mirror-image” version of the amino acid cysteine can dramatically slow the growth of certain cancers while leaving healthy cells largely untouched. Unlike most anticancer treatments that harm normal tissues, this molecule—called…

Researchers have discovered that hedgehogs can hear ultrasound, a surprising ability that could help protect them from cars. Since road traffic kills large numbers of hedgehogs, scientists believe ultrasonic repellents might be used to steer them away from…

Decades of data from over 80,000 great tits reveal that extreme weather can shape the fate of baby birds. Cold snaps soon after hatching and heavy rain later in development shrink nestling body mass and reduce survival odds. But moderate warm spells can actually…

A study from Kobe University has uncovered a surprising partnership between Japanese red elder plants and Heterhelus beetles. The beetles pollinate the flowers but also lay eggs inside the developing fruit. The plant responds by dropping many of those fruits…

Researchers have uncovered a universal pattern showing how temperature affects life on Earth. Across thousands of species—from microbes to reptiles—performance rises gradually with warming until an optimal temperature is reached, after which it drops sharply.…

Three years ago, a train derailment spilled hazardous chemicals into the Ohio community.

Scientists at Arizona State University have uncovered surprising new ways bacteria move, even without their usual whip-like propellers called flagella. In one study, E. coli and salmonella were found to spread across moist surfaces by fermenting sugars and…

Researchers studying over 8,400 colonoscopies discovered that having both adenomas and serrated polyps in the bowel can raise the risk of serious precancerous changes by up to five times. These two polyp types may represent separate cancer pathways that can…

A severe case of COVID-19 or influenza could increase the risk of lung cancer later on, according to new research. Scientists discovered that serious viral infections can alter immune cells in the lungs, leaving behind chronic inflammation that may help tumors…

In medieval Denmark, people could pay for more prestigious graves closer to the church — a sign of wealth and status. But when researchers examined hundreds of skeletons, they discovered something unexpected: even people with stigmatized diseases like leprosy…

NIH-funded, automated clinical decision support could facilitate timely interventions for at-risk patients years before they might otherwise seek help.

Tiny plastic particles may be quietly threatening brain health. New research suggests microplastics—now widely found in food, water, and even household dust—could trigger inflammation and damage in the brain through multiple biological pathways. Scientists…

Researchers have identified two gut bacteria that can produce serotonin, a key chemical that regulates bowel movements. In experiments with mice lacking serotonin, the microbes boosted serotonin levels, increased nerve cells in the colon, and normalized intestinal…

A newly identified Australian tree has been dubbed the “zombie” tree because it’s alive but unable to reproduce. Myrtle rust repeatedly kills its young growth, stopping the species from flowering or making seeds. Scientists are scrambling to grow disease…

Cambridge scientists have discovered a light-powered chemical reaction that lets researchers modify complex drug molecules at the final stages of development. Unlike traditional methods that rely on toxic chemicals and harsh conditions, the new approach uses…

Scientists have uncovered an enormous hidden archive of plant DNA that has endured for more than 400 million years. By comparing hundreds of plant genomes, researchers identified more than 2.3 million regulatory DNA sequences that act like genetic switches…
