Phys.org / Tiny 'whirlpools' discovered in atom-thin semiconductor
Monash University-led researchers have directly imaged tiny swirling structures inside an atomically thin semiconductor, opening new possibilities for future low-energy electronic technologies. Published in Science Advances, ...
Phys.org / Parakeets, male or female, love a good fight
In a study of monk parakeets, researchers at the University of Cincinnati and Duke University found that sex has little to no impact on who initiates fights, who is targeted or who rises in the dominance hierarchy.
Phys.org / Antibody cocktails could steer viruses into evolutionary dead ends
When a virus mutates, the world usually finds out the hard way. Variants of influenza and SARS-CoV-2 can slip past vaccines and antibody drugs before scientists fully understand what has changed. A new study from Harvard's ...
Phys.org / A painting signed 'L daVinci': Analysis reveals Renaissance pigments and later alterations
Researchers at Uppsala University have analyzed the color pigments in a historical painting signed "L daVinci." Most of the pigments are consistent with materials used during the Renaissance, while a more recent pigment appears ...
Phys.org / Radiation-tolerant rotifers rebuild broken chromosomes over successive generations
DNA repair mechanisms are essential for maintaining the integrity of our genome. When they malfunction, they can cause disease or contribute to the development of cancer. Nature, however, offers remarkable examples of organisms ...
Phys.org / Peptide position determines whether gold nanoparticles branch or stay spherical
The position of biomineralization peptides within liposomes can influence how gold nanoparticles grow, reports a research team from the Institute of Science Tokyo. Peptides localized at the membrane interface promote branched ...
Phys.org / Cancer-linked protein binds to chromosome in unexpected way, study finds
A new 3D structure of a cancer-linked protein bound to its cellular partner reveals details of how the protein binds to chromosomes and could offer insights for future disease treatments. The protein—BRD4—plays a critical ...
Phys.org / Chocolate's new climate threat: Too much rain
Cocoa farmers in West Africa cannot stop intense downpours from damaging their crops. But they may be able to anticipate the risk and prepare, protecting both their livelihoods and their plants, the source of one of the world's ...
Phys.org / Anger, hope and compassion do little to spur more climate donations
Emotional mechanisms are frequently used to inspire good environmental behavior. But how effective are they at inspiring actual sustainable change? Perhaps not as much as previously believed, according to a new study that ...
Phys.org / Structural study explains how cells stabilize protective membrane pockets
Our cells' membranes have many functions. They not only provide mechanical protection but also precisely control which substances enter or leave cells. If they fail to perform these tasks, disease can result. Their structure ...
Phys.org / How can countries prevent shocks and disasters from turning into food crises? Analysis points to resilience measures
Floods, wildfires, conflicts, earthquakes, economic shocks, hurricanes or epidemics: These unexpected and often dramatic events affect people's lives and jobs, destroy crops, wipe out livestock and stored food, contaminate ...
Phys.org / Evolutionary home advantage: Field experiment reveals adaptation to be surprisingly local
A research team from the University of Bern has shown in a large-scale field experiment that populations of the same fish species can be much more fine-tuned to their local environments than previously thought. Habitats that ...
