Some stars appear to defy time itself. Nestled within ancient star clusters, they shine bluer and brighter than their neighbors, looking far younger than their true age. Known as blue straggler stars, these stellar oddities ...

Deep neural networks (DNNs) have become a cornerstone of modern AI technology, driving a thriving field of research in image-related tasks. These systems have found applications in medical diagnosis, automated data processing, ...

Researchers at Leipzig University and TU Dresden have succeeded in developing biological switches that can selectively turn ion channels on and off using light pulses. Initial applications show that it is possible, for example, ...

Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke. After that, many patients are ...

A new transceiver invented by electrical engineers at the University of California, Irvine boosts radio frequencies into 140-gigahertz territory, unlocking data speeds that rival those of physical fiber-optic cables and laying ...

UT Southwestern Medical Center researchers have discovered that increasing the levels of a protein called BACH2 makes engineered cancer-fighting immune cells behave more like stem cells, improving their therapeutic effectiveness. ...

Already recognized for its excellence and even adopted for operational weather forecasting, the European Space Agency's Arctic Weather Satellite has now fulfilled its most important role. This small prototype mission has ...

Research led by scientists at the University of Bristol and co-authored by top US nutritional experts reveals that people following a completely unprocessed diet ate more than 50% greater amounts of food than those eating ...

Men assess potential rivals that have a larger penis as more of a threat, both physically and sexually, according to a study by Upama Aich at the University of Western Australia and colleagues, published in PLOS Biology.

An international research team led by scientists at Waseda University and Tohoku University has discovered an extraordinary quasar in the early universe that hosts one of the fastest-growing supermassive black holes known ...

A team from Würzburg has fundamentally changed our understanding of platelet biology. The researchers demonstrate that the surface protein integrin αIIbβ3 is not only a key molecule in blood clotting, but can also act ...

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that this ring is too strict: ...
