Phys.org / Researchers identify class of 'oddball' meteorite that killed the dinosaurs
A rare CO chondrite meteorite was the probable impacter that struck Earth 66 million years ago, wiping out 75% of Earth's species, including nonavian dinosaurs. These findings are published in Science Advances. Researchers ...
Phys.org / Amazon soy pact collapse could add 1.4 million hectares of deforestation by 2036
The collapse of a landmark Amazon soy pact will drive at least 1.4 million hectares (3.5 million acres) of extra deforestation in Brazil over the next decade, releasing carbon emissions equal to Canada's annual output, according ...
Phys.org / Wild snapdragons paint themselves in subtle shades to attract bees
Just as careful blending of eye shadow can make a difference to our looks, a recent study has shown how flowers go to considerable trouble to fine-tune their shades. In the relentless competition to attract bees, a slight ...
Phys.org / Thinner wires, faster electrons: Quantum material challenges copper at chip scale
Electrical interconnects may very well be the unsung heroes of modern microchips. These tiny wires—typically made of copper due to its high conductivity—string together the billions of transistors that drive our computers ...
Phys.org / Prototype bicycle tire uses silk to outperform nylon in strength and endurance
Researchers in Thailand have developed a prototype high-performance bicycle tire that replaces conventional nylon fabric reinforcement with natural silk. The team combined laboratory-scale material testing with pilot-scale ...
Phys.org / Canadian wildfire smoke linked to fewer bird sightings in New York State
Despite burning hundreds of miles away, Canadian wildfires have become a familiar source of disruption in New York state.
Phys.org / AI-designed proteins help scientists see inside living cells
Cells are like metropolises, home to millions of molecular residents. If one were to stand atop a high-rise, trying to identify most of its inhabitants would seem an impossible task. Even with the sophisticated imaging tools ...
Phys.org / Researchers identify 'dimmer switch' for plants' immune system
As sulfur becomes increasingly scarce in soils worldwide, scientists are studying how plants decide whether to invest limited resources in growth or defense.
Phys.org / Giant planets could act as dark matter detectors
Researchers in the U.S. have carried out the most stringent tests to date of the idea that an ultraviolet glow in the atmospheres of giant planets could partly arise through the indirect interaction between dark matter and ...
Phys.org / A scheme to verify gates of a quantum computer without examining devices
Quantum computers, systems that process information using the principles of quantum mechanics, could solve some problems that cannot be tackled by the classical computers currently used worldwide. Despite their potential, ...
Phys.org / A source of extremely high-energy particles in the Milky Way identified
Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than what human-made accelerators can produce. Considering human-made accelerators, such as the Large Hadron ...
Phys.org / Aboriginal people harvested this native grass for millennia: Scientists find an odd trait in its DNA
Seen from the air, Channel Country resembles a vibrant, vast tapestry, with a network of waterways crisscrossing the land. Spread across more than 280,000 square kilometers (108,000 square miles) in outback Australia, it ...
