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 wh…
Hidden receptor interactions may explain past failures of brain disorder drugs
Metabotropic glutamate receptors, which are important but difficult drug targets, interact in surprisingly varied ways with their principal regulatory proteins, according to two n…
Scientists discover dispersal mechanism and new gene family in harmful E. coli strains
Researchers from Tokyo Metropolitan University have identified how certain dangerous bacteria spread. They studied chain-like adherence pattern (CLAP) varieties of Shiga toxin-pro…
From atomic vibrations to laboratory mechanics: Bridging 20 orders of magnitude in time
How can we predict the way a real material, such as a polymer, responds mechanically over timescales ranging from the ultrafast motion of atoms to the slow deformations measured i…
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 the…
What’s Next for Summit’s Carbon ‘Pipeline to Nowhere’?
The Iowa Utilities Commission is moving toward hearings on the second phase of a proposed carbon dioxide pipeline, which would add hundreds of miles of lines to a project already …
AI models enable cross-species mapping of cell biology
Researchers at Stanford Medicine have developed two new artificial intelligence models of the biological cell. The first, called universal cell embedding, paved the way for a seco…
Every animal, even the smallest rodent, deserves safe anesthesia, say researchers
Laboratory animals are anesthetized to avoid pain during invasive procedures. Anesthesia is necessary for these animals' welfare, but it is not always without problems: Substandar…
Three DNA loops prove essential for efficient wing tissue regeneration in fruit flies
After an injury, DNA not only changes its activity but also the way it is organized spatially within the cell nucleus. In this process, certain regions of DNA establish new physic…
Webinar 9/23: NASA CSDA Program Update 2026
This webinar will provide an overview of the CSDA program’s goals and activities, including the new Cal/Val initiative, and more.
Forest fire smoke reduces bird diversity, study suggests
When forests burn, the direct consequences are obvious: houses go up in flames and habitats are destroyed. The damage caused by smoke extending far beyond the fire area is less vi…
Common wastewater pollutant turns male minnows into poorer parents and fiercer rivals
A team of researchers has found that a common wastewater pollutant turned male fathead minnows into worse fathers and fiercer rivals, revealing ecological impacts that laboratory …
US ‘super-emitters’ of planet heating methane identified by satellite analysis
Energy Transfer, whose CEO is a major Trump donor, named as biggest single methane producer in new rankingsDown a short gravel track in a largely nondescript corner of Louisiana s…
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, …
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 w…
Active black holes reveal star-forming rings and shock waves in nine nearby galaxies
A new study of nine nearby galaxies has shown that actively growing supermassive black holes may contribute to, rather than prevent, star formation in their host galaxies.
Turning a potent greenhouse gas into a valuable pharmaceutical building block using light
The trifluoromethyl group, or CF₃, is widely used in pharmaceuticals. When added to organic molecules, it can improve metabolic stability and membrane permeability, making it high…
Researchers identify rubber-related chemicals in Swiss milk
Every year, tire and road wear release an estimated 6 million tons of rubber particles into the environment, some of which eventually reach agricultural land through the air, wate…
First confirmed Diplodocus outside North America reshapes Late Jurassic migration picture
In a discovery that challenges our understanding of dinosaur distribution during the Late Jurassic period, paleontologists have identified the first evidence of the iconic Diplodo…
The warmest summer on record: 2026 hit a scorching new high in the US
Temperatures and precipitation are hitting new extremes.
Only 1 out of every 5 amphibian type localities in Ecuador are in protected areas
In taxonomy, the location where specimens used to formally describe a new species are collected is called a type locality. These sites can be thought of as the species' formal bir…
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 …
Neutral radicals unlock porous organic semiconductors without chemical doping
Researchers at the Center for Research in Biological Chemistry and Molecular Materials (CiQUS) at the Universidade de Santiago de Compostela (USC) have developed a new strategy fo…
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 an…
