Phys.org / Ancient teeth from Siberia rewrite the plague's timeline, dating back to over 5,500 years ago
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.
Phys.org / Cosmic neutrino 'whispers' may surface in 5,000-day Super-Kamiokande signal
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 ...
Phys.org / DNA-based nanoswitch can flip in milliseconds and stay in one state for days without continuous forcing
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 ...
Phys.org / When companies face hostile takeover threats, they turn to ESG, and the whole community benefits
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 ...
Tech Xplore / Robots can now 'see' touch thanks to a new color-changing tactile sensor
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 ...
Phys.org / 400-year-old painting reveals a bat's secret diet
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 ...
Phys.org / Congo River freshwater rides 49-day Atlantic eddy to travel 200 kilometers offshore
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 ...
Phys.org / Trained AI outperforms biologists at spotting salmon lice
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 ...
Phys.org / How a giant planet survived its star's death, then migrated inward
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 ...
Phys.org / A rare dinosaur fossil from Antarctica is found tucked away in a drawer
Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.
Phys.org / Physicists and AI model Claude 'collaborate' to prove a 10-year-old jamming conjecture
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 ...
Phys.org / Study demonstrates neurotransmitter communication in immune cells directly for the first time
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 ...
