Scientists have found the oldest known evidence of the plague, which sparked deadly outbreaks dating back about 5,500 years ago—some 200 years earlier than previously thought.

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult to detect. Research on ...

Scientists have engineered a nanoscale switch using DNA "origami." Inspired by macroscale mechanical switches, the device achieves long-term functionality without the continuous forcing mechanism that past versions required ...

When a company faces the prospect of a hostile takeover, its board may reach for traditional anti-takeover defenses. "Poison pills," for instance, allow existing shareholders to buy additional shares at a discount, diluting ...

Engineers at Queen Mary University of London have built a new color-changing tactile sensor, which allows robots to "see" and touch in real-time. The novel idea was invented by Giacomo Sasso, a postdoctoral researcher at ...

Natural historians have many observational techniques in their toolkit for learning about the natural world: tagging animals with tracking devices, recording sounds, analyzing droppings or simply watching and counting. As ...

The Congo River is the second-largest river in the world, releasing an average of 40,000 cubic meters of water per second into the Atlantic Ocean. This huge discharge rate creates a large plume of fresh water that fans out ...

Researchers have taken over 120,000 images of salmon lice larvae in seawater and used them to train AI models. The models were much faster and more accurate than experienced biologists at identifying the parasites that feed ...

When astronomers discovered a giant planet orbiting a dead star in 2020, they wondered how it survived its star's violent demise. Now, observations from NASA's James Webb Space Telescope (JWST) may finally explain the planet's ...

Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.

A mathematical problem that had remained unsolved for more than 10 years in the physics of complex systems has finally been resolved through an unusual collaboration: one involving two theoretical physicists and an artificial ...

Researchers at the University of Münster and Ruhr University Bochum have demonstrated for the first time in real time that the body's own defense cells use catecholamines—neurotransmitters such as dopamine and adrenaline—to ...
