Astronomers have found the biggest stream of stars ever recorded. This tendril of stars is extraordinarily faint, but it and others like it could eventually help us unveil the true nature of dark matter.

The stream of stars, called the Giant Coma Stream, appears to float unmoored from any particular galaxy in the Coma galaxy cluster, about 300 million light years away from Earth. Javier Román at the University…

Homo sapiens ventured into Neanderthal territory in Europe much earlier than previously thought, according to an archaeological study published in Science Advances on Wednesday. Up to now, archaeological discoveries had indicated that Neanderthals disappeared from the European continent about 40,000…

Long-Enduring COBOL May Still Have a Shelf Life

While machine learning has been around a long time, deep learning has taken on a life of its own lately. The reason for that has mostly to do with the increasing amounts of computing power that have become widely available—along with the burgeoning quantities of data that can be easily harvested and used to train…

Deleting a Protein May Prevent Heart Attacks and Strokes

Macrophages travel through our arteries, gobbling fat the way Pac-man gobbled ghosts. But fat-filled macrophages can narrow blood vessels and cause heart disease. Now, UConn Health researchers describe in Nature Cardiovascular Research how deleting a protein could prevent this and potentially prevent heart attacks and strokes in humans. Macrophages are large white blood cells that…
