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 / Long-sought Zhang-Rice singlet visualized directly in cuprate superconductor
Superconductors are materials that conduct electricity with zero electrical resistance below specific temperatures. Most of these materials become superconducting at very low temperatures, but some also exhibit superconductivity ...
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 ...
Phys.org / Recyclable glue bonds underwater in seconds and holds for years
Most glues need a dry surface to stick properly. Bonding materials underwater is challenging because water forms a thin film on any surface, so instead of an adhesive touching a material directly, it touches a layer of water, ...
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 ...
Phys.org / River shipping emits nearly one-quarter of global shipping CO₂, analysis finds
River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make ...
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, ...
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 ...
Medical Xpress / 'Locked' cancer therapeutic activates in tumors, limiting off-target exposure in mice
Although there are many cancer treatments available today that effectively eliminate abnormal cells, these therapies may also damage healthy cells, leading to unwanted side effects.
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 ...
Phys.org / Soft-bodied sea slug reconfigures anatomy to simplify feeding control
Made entirely of muscle, with no rigid skeleton, muscular hydrostats like octopus arms, elephant trunks and human tongues can move in ways traditional mechanical systems cannot. Between crawling across the seafloor, picking ...
Phys.org / Fungal age remains elusive as underground networks continually grow, split and recycle
Some of Earth's oldest living organisms may be right beneath our feet: not ancient trees or coral reefs but fungi. Yet despite their ubiquity and importance, scientists still don't know how long most fungi can live—or even ...
