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 chemical method makes it easier to select desirable traits in crops
Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists ...
Phys.org / Whale hunting began 5,000 years ago in South America, a millennium earlier than previously thought
The hunting of large whales goes back much further in time than previously thought. New research from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) and the Department ...
Phys.org / North Pacific winter storm tracks shifting poleward much faster than predicted
Alaska's glaciers are melting at an accelerating pace, losing roughly 60 billion tons of ice each year. About 4,000 kilometers to the south, in California and Nevada, records for heat and dryness are being shattered, creating ...
Phys.org / Blazar Ton 599's complex variability investigated by long-term observations
Using the Whole Earth Blazar Telescope (WEBT), an international team of astronomers have performed long-term photometric observations of a luminous blazar known as Ton 599. Results of the observations, published in the Astronomy ...
Phys.org / Reviving antibiotics with two-faced nanoparticles
Over the decades, many strains of disease-causing bacteria have evolved defenses to even the most potent antibiotics, setting off a growing health crisis. The rise of antibiotic-resistant "superbugs" has also set off an arms ...
Phys.org / Active solar region observed for record 94 days
In May 2024, the strongest solar storm in twenty years raged. An international team led by ETH Zurich observed it. Their findings are now helping to improve space weather forecasts.
Phys.org / Fault-tolerant quantum computing: Novel protocol efficiently reduces resource cost
Quantum computers, systems that process information leveraging quantum mechanical effects, could soon outperform classical computers on some complex computational problems. These computers rely on qubits, units of quantum ...
Phys.org / Scientists find more active black holes in dwarf and Milky Way-sized galaxies by cutting through glare of star formation
Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active black holes.
Medical Xpress / SARS-CoV-2 is on the decline in animals, researchers find
During the first few years of the COVID-19 pandemic, the virus SARS-CoV-2 was detected in an increasing number of non-human animal species. This included many wild animal species as well as domestic animals such as dogs and ...
Medical Xpress / Assisted reproductive technology associated with higher risk of childhood atopic diseases
Collaborating institutions in Taiwan report higher risks of atopic disease among children conceived via assisted reproductive technology compared to those conceived naturally.
Phys.org / Identifying where lithium ions reside in a new solid-state electrolyte that could lead to improved batteries
Recent research published in Science introduces a promising solid electrolyte material that could improve the performance of next-generation lithium batteries, particularly at lower temperatures. Illinois Institute of Technology ...
