Medical Xpress / How the brain fine-tunes fear as threats fade
Researchers at Tulane University have identified brain circuits that help determine how fear responses change as perceived threats diminish, offering new insight into how the brain regulates defensive behavior and why those ...
Phys.org / How did Venus become a hellscape? 234,000 simulations reveal four possible paths
Venus is increasingly becoming a touch point for our studies of exoplanets, as missions like the James Webb Space Telescope (JWST) and the upcoming Habitable Worlds Observatory (HWO) begin to characterize rocky exoplanets ...
Phys.org / 'Cool' detectors cut neutrino mass upper limit by an order of magnitude
Their mass is extremely low, but how light are neutrinos really? A collaboration comprising German and international research groups has optimized its experiments to determine the mass of these "ghost particles." In doing ...
Tech Xplore / AI system learns to prevent warehouse robot traffic jams, boosting throughput 25%
Inside a giant autonomous warehouse, hundreds of robots dart down aisles as they collect and distribute items to fulfill a steady stream of customer orders. In this busy environment, even small traffic jams or minor collisions ...
Phys.org / Self-cleaning fabric could eliminate the need for detergent
Detergents may begin their journey by cleaning our clothes, but they end up contaminating the environment, flowing into rivers, ponds, and oceans, where they severely disrupt aquatic animal life. Even after wastewater treatment, ...
Phys.org / How plants stop growing to survive stress: Retired scientist's persistence reveals insight to boost farm yields
UC Riverside researchers have identified a mechanism that allows plants to rapidly slow growth in response to extreme environmental stress. The finding could help farmers grow more resilient crops, and one researcher continued ...
Phys.org / Shell-cracking turtles defied mass extinction at the end of the Cretaceous period
The mass extinction at the boundary between the Cretaceous and Paleogene periods was catastrophic, wiping out much of life on Earth. Vertebrate groups that dominated at the time, such as dinosaurs and many large marine reptiles, ...
Phys.org / A captive chimp's instrumental performances hint at the evolution of vocal externalization
In February 2023, a resident at Kyoto University's Center for the Evolutionary Origins of Human Behavior—EHUB—treated researchers to a spontaneous musical performance. Ayumu, a 26-year-old male chimpanzee, removed floorboards ...
Phys.org / RNA-guided CRISPR system activates gene expression
In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing ...
Phys.org / The hidden cost of sperm storage: Ejaculates found to deteriorate across the animal kingdom
Current World Health Organization (WHO) guidelines typically recommend two to seven days of abstinence before taking semen samples or assisted reproduction. However, a new study led by Oxford University researchers suggests ...
Phys.org / Laser-modified graphene enables molecule-thick films to grow only where needed
Researchers from the University of Jyväskylä and Aalto University have developed a new method based on laser modification, which allows metal-organic materials to be grown locally one molecule-thick layer at a time. The method ...
Phys.org / Microtubules discovered to play an active role in correctly distributing chromosomes during cell division
Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling role. The findings, published ...
