Phys.org / Small-scale farmers produce more of the rich world's food than previously thought
Who grows our food? This seemingly simple question is getting harder to answer in a world where our food crosses borders to get to our plate.
Phys.org / Cross-border pollution tracking reveals unequal distribution of risk and responsibility
Microscopic airborne particles known as PM2.5 contribute to 100,000 premature deaths in the United States each year. A new University of Notre Dame study finds that 40% of these deaths can be attributed to pollution that ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Corals sleep like us, but their symbionts never rest
Sleep is essential for much of the animal kingdom. During the night, neuron and tissue repair mechanisms are activated to aid recovery from daily activity. This is risky: organisms that sleep are more vulnerable to predators. ...
Phys.org / Quantum batteries could quadruple qubit capacity while reducing energy infrastructure requirements
Scientists have unveiled a new approach to powering quantum computers using quantum batteries—a breakthrough that could make future computers faster, more reliable, and more energy efficient.
Phys.org / Novel ferroelectric ultraviolet photodetector achieves near-10,000-fold speed increase
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have developed a new ferroelectric ultraviolet photodetector material that overcomes the long-standing performance limitations of conventional ...
Phys.org / A protein thought to play a supporting role in DNA replication actually facilitates the whole process
Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its code and build new strands. ...
Phys.org / Changing land use can increase threat of animal‑to‑human disease spread
Changes to land use can directly heighten the risk of diseases spreading from animals to humans, new University of Stirling–led research has shown. The study, led by Dr. Adam Fell of the University's Faculty of Natural ...
Phys.org / Rare fossils reveal 91 new species that survived ancient mass extinction
Almost a hundred new animal species that survived a mass extinction event half a billion years ago have been discovered in a small quarry in China, scientists revealed Wednesday.
Phys.org / Proton-trapping MNene transforms ammonia production for food security and economic growth
With a new electrochemical synthesis via an electrochemical nitrogen reduction reaction (NRR), achieving carbon-free ammonia production is closer to reality through work from Drs. Abdoulaye Djire and Perla Balbuena, chemical ...
Phys.org / Google unveils AI tool probing mysteries of human genome
Google unveiled an artificial intelligence tool Wednesday that its scientists said would help unravel the mysteries of the human genome—and could one day lead to new treatments for diseases.
Phys.org / NASA telescopes spot surprisingly mature cluster in the early universe
Astronomers at The University of Manchester have played a leading role in the discovery of a new cosmic object that is much larger than anything astronomers have seen before in the distant universe. This new discovery captures ...
