Phys.org / 60,000-year-old traces of world's oldest arrow poison reveal early advanced hunting techniques
Researchers from South Africa and Sweden have found the oldest traces of arrow poison in the world to date. On 60,000-year-old quartz arrowheads from Umhlatuzana Rock Shelter in KwaZulu-Natal, South Africa, researchers have ...
Phys.org / New evidence for a particle system that 'remembers' its previous quantum states
In the future, quantum computers are anticipated to solve problems once thought unsolvable, from predicting the course of chemical reactions to producing highly reliable weather forecasts. For now, however, they remain extremely ...
Phys.org / Vera C. Rubin Observatory spots record-breaking asteroid in pre-survey observations
Astronomers analyzing data from Vera C. Rubin Observatory have discovered the fastest-ever spinning asteroid with a diameter over half a kilometer—a feat uniquely enabled by Rubin. The study provides crucial information ...
Phys.org / Snowflake-like emergence phenomenon discovered in metal nanocrystals
Whether they're tickling your nose, hugging your eyelashes or melting on your tongue, few winter wonders are as fascinating as snowflakes.
Phys.org / Solar physicists discover long-hidden source of gamma rays unleashed by flares
Solar physicists say they have found a key source of intense gamma rays unleashed when Earth's nearest star produces its most violent eruptions.
Phys.org / Plasma rings around M dwarf stars offer new clues to planetary habitability
How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie's Luke Bouma is exploring a new way to probe this critical question—using naturally occurring space ...
Phys.org / Dogs' dinners can have greater climate impact than those of their owners
Dogs fed on premium, meat-rich pet food can have a bigger dietary carbon pawprint than their owners, according to the largest study into dog food's climate impact.
Phys.org / Optics research uses dim light to produce bright LEDs
Researchers at Princeton and North Carolina State University have developed a technique that substantially improves the ability to convert low-energy light into a high-energy version. The method has immediate applications ...
Phys.org / Nature-inspired computers are shockingly good at math
Neuromorphic computers, inspired by the architecture of the human brain, are proving surprisingly adept at solving complex mathematical problems that underpin scientific and engineering challenges.
Phys.org / Engineers create water-saving sand layer to improve plant resilience during drought
The Anasazi, a once-flourishing tribe in the American Southwest, lived on bounties of corn, squash and beans. In 1276 A.D., however, a long, unforgiving drought made agriculture untenable, forcing them to migrate away from ...
Phys.org / THz spectroscopy system bypasses long-standing tradeoff between spectral and spatial resolution
Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next-generation applications, including high-speed wireless communications, chemical sensing, and advanced ...
Phys.org / The Milky Way's black hole is hiding an explosive past, evidence suggests
Our galaxy's supermassive black hole is famous for being one of the dimmest in the universe. Evidence from a new space telescope shows that might not always have been the case.
