Phys.org / Beyond the algorithm, online negativity takes on a life of its own as users try to stand out
It doesn't take a scientist to figure out that social media can trend toward the negative. But it might take one to figure out why. In a new paper in PNAS, professor of psychology Joshua Conrad Jackson and colleagues show ...
Phys.org / Muon g-2 experiment places new constraints on a forbidden property of muons
A year after its final muon magnetic anomaly announcement, the Muon g-2 collaboration reports a new measurement of a different property of the muon: its electric dipole moment. The work is published on the arXiv preprint ...
Medical Xpress / A timed liver signal may boost fat breakdown, pointing to potential metabolic treatments
What if one of the keys to a healthier metabolism is understanding how and when the liver communicates with the rest of the body?
Phys.org / Mathematical model shows how birds create a synchronized dawn chorus
Every morning, groups of birds start singing and chirping around the same time, typically when the sun starts rising. While zoologists have been studying this collective bird behavior, called the dawn chorus, for decades, ...
Phys.org / Famous oddball quasar isn't X-ray weak after all, astronomers say
For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe ...
Phys.org / Genome study reveals centromeres as one of the fastest-changing regions in human DNA
A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite their essential role, ...
Science X / Why eye contact may help babies learn: A hidden link between two brains
Have you ever noticed how babies get hooked the moment someone makes eye contact with them? That eye contact is not only cute; it may also send a powerful message to a baby. For years, scientists have been investigating whether ...
Medical Xpress / Astrocytes directly regulate brain circuits that consolidate memories during sleep, study reveals
Research has shown that a good night's sleep has many benefits, including memory consolidation. How sleep enables the brain to strengthen memories is still not completely understood, but a new study published in Neuron reveals ...
Phys.org / One in four cocoa farm audits contain data manipulated to meet sustainability targets, researchers find
ETH researchers have used a sustainability program for cocoa cultivation in Côte d'Ivoire to demonstrate that, in one in four cases, data was manipulated to meet the program's requirements. If the auditor were aware of the ...
Medical Xpress / Brain circuit keeps tabs on what just happened to aid judgment of what's happening now
A brain must constantly cope with the highly variable, fast-paced nature of the world when trying to judge what's going on around it. On the one hand, it has to be open to whatever new sensory information may come its way, ...
Tech Xplore / Brief physical access may let attackers alter Boeing 737 flight instructions
Physical access to an aircraft has not typically been considered a cybersecurity risk—but it should be, according to a team of computer scientists at the University of California San Diego. In a paper presented Aug. 13 at ...
Tech Xplore / Why AI may boost carbon emissions instead of cutting them
AI data centers get a bad rap, not least because of concerns that they drive climate change by consuming massive amounts of electricity. But one potentially larger impact of AI on global carbon emissions may be that it's ...
