Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the bo…

A Rutgers study suggests GLP-1 drugs such as Ozempic and Wegovy may weaken the link between impulsive tendencies and violent behavior. The surprising finding hints that these medications could affect how people act on impulses, though researchers stres…

Scientists have discovered a new Amazonian spider with an astonishing disguise: it looks like a parasitic fungus. The species, Taczanowskia waska, mimics both the appearance and behavior of the fungus, helping it stay hidden from predators and potentia…

Scientists have digitally preserved the world’s most endangered marine mammal by creating highly detailed 3D models of a vaquita skeleton using advanced imaging technology. The virtual archive provides an unprecedented look at the species and could hel…

Exposure to a common plastic chemical before and shortly after birth may have lasting effects on behavior. Researchers found that male rats exposed early in life to DEHP—a plasticizer used in products ranging from medical devices to toys—showed signifi…

A small clinical trial suggests that probiotics may offer a surprising mental health boost for older adults with depression. Seniors who took a daily probiotic alongside their regular antidepressant treatment experienced slightly greater improvements i…

A clever nanoscale redesign may have solved one of superconductivity’s biggest problems. Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at hig…

Scientists at Mayo Clinic have uncovered a surprising new way the kidneys conserve water, revealing a hidden backup system that works independently of the hormone long believed to control the process. The discovery emerged when researchers testing an o…

A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials. Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much m…

A minimally invasive treatment that blocks inflammation-driving blood vessels in the knee provided significant pain relief and improved function for osteoarthritis patients, with benefits lasting at least a year. The procedure was safe, highly successf…

Scientists are beginning to explore a hidden world of thousands of food chemicals that go far beyond the nutrients listed on nutrition labels. This “nutritional dark matter” may hold the key to understanding disease risk, healthy aging, and why differe…

Depression appears to change what children notice in the faces around them, but the effect depends on family history. Kids with a higher inherited risk became more focused on sadness, while lower-risk children lost some of their natural attention to ha…

Diabetes and dementia appear to be closely intertwined, with each condition potentially influencing the other. Problems with insulin and glucose can affect the brain’s energy supply, increase inflammation, and damage blood vessels linked to memory loss…
