From butterflies to peacocks, bold circular "eyespots" are among nature's most eye-catching patterns. But why do they appear in some animals and not others? A new study of skates and rays finally provides an answer—and it ...

In the race to make AI models not just reason better but respond faster, latency—the delay before an answer appears—is often treated as a purely technical constraint, something to minimize and move past. But how is this relentless ...

New clues from genetic research may help explain what causes the most common heart defect present at birth. Researchers at KTH Royal Institute of Technology and Karolinska Institutet have identified rare DNA changes during ...

Even after fires, severe droughts, and windstorms, the vegetation in degraded Amazonian forests demonstrates a high capacity for regeneration, including tree species. However, recovery occurs under new ecological conditions, ...

Researchers at Hannover Medical School (MHH) have developed a method for the efficient production of human immune cells, such as macrophages, in medium-sized bioreactors. These immune cells can be derived from induced pluripotent ...

A healthy diet, weight loss, and increased physical activity can effectively prevent type 2 diabetes. However, not all individuals at elevated diabetes risk benefit equally from lifestyle interventions. People classified ...

A new genetic study shows that cultural diversity in the so-called Southern Cone—the roughly triangular southernmost part of South America—was strongly influenced by extensive human migration. An international research team ...

The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows. The findings ...

In everyday life, our genetic material is constantly under attack from many factors. Environmental influences such as light, along with internal processes like inflammation, can generate oxidative stress that damages DNA ...

Penn Engineers have developed SmartDJ, an AI-powered editor that lets users modify immersive audio environments with simple instructions in everyday language, with potential applications in virtual reality, augmented reality, ...

People getting their teeth pulled or drilled by dentists in the United States are still much more likely to get powerful opioid medications than dental patients in other developed countries or even the U.S. territory of Puerto ...

Mud-rich coastlines could face a greater tsunami risk, at least that may have been the case for the 2011 Tōhoku-oki tsunami that killed more than 19,000 people and led to the Fukushima Daiichi nuclear disaster. According ...
