Phys.org / Laser bursts flip nanoscale magnetic vortices at blistering speeds, opening a path to brain-like spintronics
Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as it ultimately allows ...
Phys.org / Atlantic current shows two-decade decline across four deep-ocean monitoring sites
A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on ...
Phys.org / CHIME tracks a hyperactive repeating fast radio burst source
Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an international team of astronomers has performed radio observations of FRB 20220912A—a highly active source of repeating fast radio bursts. Results of the ...
Phys.org / Chernobyl's exclusion zone is a beacon of biodiversity—but it faces new threats from Russia's invasion
April 26 marks the 40th anniversary of the explosion at Reactor 4 of the Chernobyl nuclear power plant in Ukraine. The accident caused the largest ever release of radioactive material into the environment, and at the time ...
Phys.org / Low wages, poor training put security guards—and the public—at risk, study finds
Tens of thousands of private security guards in California play a critical role in public safety, but poverty-level wages and poor training put both the guards and the public at risk, according to a new study by the UC Berkeley ...
Science X / These ants can strip cocoa bare, but one farm tree changes the whole battle
Cocoa cultivation in so-called agroforestry systems is widespread in the Peruvian Amazon rainforest. There, cocoa plants grow alongside other trees in the same area. The problem is that leaf cutter ants also like to build ...
Medical Xpress / AI squeezes individual breast cells to learn how to spot cancer risk
Researchers at City of Hope, a cancer research and treatment organization, and the University of California, Berkeley, have created a novel microfluidic platform that can assess women's breast cancer risk at the cellular ...
Phys.org / Education saves lives: New study reveals global link between learning and longevity
A major international study involving researchers from The University of Manchester has found that education is one of the strongest predictors of how long people live. Using a new statistical approach to overcome gaps in ...
Tech Xplore / Fusion power may never be cost-competitive with renewables, study warns
Fusion power plants are sites at which electricity could be generated via a process known as nuclear fusion, which entails the merging of two atomic nuclei into a single heavier nucleus. This process is known to generate ...
Phys.org / A philosopher's serpent: New grass-green pitviper discovered in China's Giant Panda National Park
Draped in a uniform coat of vibrant grass-green and possessing eyes that shimmer like amber, a newly discovered pitviper is the latest hidden jewel to be found in the misty mountains of western Sichuan, China.
Tech Xplore / Tiny, knotted robots jump, fly and plant seeds
When a knot lets go, it doesn't just fall apart. It snaps. That simple observation led Penn Engineers to rethink what a knot can do. Instead of treating it as something that holds tension, they asked a different question: ...
Phys.org / Brazil unearths a bizarre beaked reptile with a trans-Atlantic prehistoric link
Paleontologists from the Federal University of Santa Maria (UFSM) have published a new study in the scientific journal Royal Society Open Science, in which they describe a new species based on a fossil skull approximately ...
