Gut bacteria can transform nitrate and plant-based iron from vegetables and other foods into protective molecules that may benefit the heart and metabolism. In experimental models, higher levels of th...
Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking neu...
An abandoned farm field became a flourishing wildflower meadow within little more than a decade, with plant diversity doubling and thousands of orchids appearing naturally. The discovery suggests that...
Researchers have found a way to slash the processing time for 3D-printed zirconia crowns from as much as 100 hours to under 30 minutes. The advance could eventually let dentists print strong, customiz...
Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ...
Researchers have used AI to uncover the DNA signature of a key genetic “switch” involved in turning genes on. After analyzing about 500,000 DNA sequences, the model identified the initiator in roughly...
A decades-old compound may point to a new way of treating obesity by making the body burn more energy rather than simply reducing appetite. In mice, TOFA increased energy use by as much as 18%, reduce...
Scientists have developed an ultrathin coating that could dramatically improve how efficiently heat is transferred during condensation. By turning tiny polymer structures once considered “defects” int...
A massive analysis involving more than 100 million people has found strong links between recreational drug use and stroke, including among younger adults. Cocaine was associated with nearly double the...
Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary fin...
Astronomers have found stars that repeatedly skim past supermassive black holes, surviving each encounter while producing a new burst of light. In some systems, those flares mysteriously fade with eve...
Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for see...
