Phys.org / Laser-plasma 'mirror' unlocks a new path to extreme light intensities
An international team of physicists has achieved a significant advance in laser science, demonstrating for the first time a practical route to dramatically boosting the intensity of high-power laser light.
Phys.org / First direct nanomagnet measurement finds switching attempts far slower than long-assumed
A compass always points north—or does it? Magnets normally maintain a stable direction of magnetization, pointing from south to north (S→N). However, this direction can change under strong magnetic fields or heat. For example, ...
Phys.org / ATLAS sets record limits on Higgs boson's self-interaction
One of the biggest open questions in particle physics today is how the Higgs boson interacts with itself. This "self-coupling" could help explain the evolution of the early universe and the mechanism that gives mass to elementary ...
Phys.org / Chalk-stream salmon could become an official sub-species
Chalk-stream salmon should be officially classified as a sub-species, new research suggests. Scientists from the University of Exeter and INRAe (France) carried out detailed genetic testing of salmon from 42 rivers in England, ...
Phys.org / Hidden nest cameras debunk long-standing myth about how cuckoos lay their eggs
An international team of ornithologists has overturned one of the oldest assumptions in natural history by directly documenting how common cuckoos lay their eggs in host nests located inside cavities. The findings, published ...
Phys.org / How cells turn mechanical forces into biochemical signals
Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. ...
Phys.org / NASA's Curiosity rover uncovers metal‑rich hotspot tied to ancient Martian lake
A team of scientists using the ChemCam instrument on NASA's Curiosity Mars rover has discovered the highest amounts of iron, manganese, and zinc ever found together in Gale Crater on Mars. Minerals with these metals were ...
Phys.org / What's in a name? Study finds two dahlia-damaging viruses are variants of same species
For decades, two different viruses were believed to be responsible for a common, untreatable disease in dahlias, a colorful, high-value flower grown worldwide. Virologists at Washington State University have now learned that ...
Phys.org / Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food
Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. ...
Phys.org / Discovery of new polymer class provides compostable alternative to conventional thermoplastics
Researchers at the University of Bayreuth have discovered a new class of polymers as part of the work carried out within the Collaborative Research Center (CRC) 1357 Microplastics. These polymers are characterized by biodegradable ...
Phys.org / Discovering a favorite pit stop and communication hub for cloud forest canopy dwellers
In his time spent in the lush canopies of Costa Rica's cloud forest, UConn Department of Ecology and Evolutionary Biology Ph.D. student Jeremy Quirós-Navarro has worked as an arborist, helped place camera traps, collected ...
Phys.org / Geoengineering could protect Amazon rainforest from climate change
Geoengineering could protect the Amazon rainforest from climate change, new research shows. Stratospheric aerosol injection (SAI) aims to artificially cool Earth by increasing the reflection of incoming solar radiation, thereby ...
