Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing ...

Many cutting-edge technologies, ranging from augmented reality (AR) and virtual reality (VR) to LiDAR (light detection and ranging) systems, rely on components that enable the precise control of light. These components include ...

Recently-revealed notebooks belonging to a late paleontologist contain the missing information needed to help researchers finish their study of a remarkable fossil discovered nearly three decades ago.

After more than a decade of research, scientists have discovered the natural mechanism behind a novel form of cell death called ferroptosis. The work, described in the current issue of Cell, points toward an entirely new ...

Snakes may be best known for slithering. But consider that these animals also perform one of the most extreme feats of posture control found in nature: They can stand nearly straight upright on a narrow perch without falling, ...

Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described ...

Hair regrowth treatment may soon take a major leap forward, as researchers in a recent study have successfully grown complete, fully functional hair follicles outside of the living body, in a dish. This was made possible ...

While sifting through the extensive data collected by NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft over the last decade, scientists discovered a familiar type of electromagnetic signal commonly caused ...

Past civilizations have been significantly affected by climate change, but how they adapted to new conditions centuries ago is less clear. In research newly published in the Proceedings of the National Academy of Sciences, ...

Greenland's largest glacier, Jakobshavn Glacier, may be edging closer to a critical threshold as meltwater runoff from the Greenland Ice Sheet accelerates in ways not seen in over a century, according to new research published ...

Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...

New minuscule fossils of Purgatorius, the earliest-known relative of all primates—including humans—have been unearthed in a more southern region of North America than ever before, and the breakthrough is providing paleontologists ...
