Phys.org / Earlier volcano warnings could mean more false alarms—but they could also save lives
Whakaari/White Island's sudden eruption in December 2019, which killed 22 people and severely injured 25 others, was New Zealand's deadliest volcanic disaster in recent history.
Phys.org / AI streamlines search for new ceramics that generate electricity
A tedious process of trial and error is normally required to discover ceramic materials that generate electricity under mechanical stress. Known as piezoelectric ceramics, these valuable next-generation materials can replace ...
Phys.org / No smartphone, no problem: Plants have their own built-in 'Season-Meter'
You may check your phone before deciding what to wear tomorrow. Plants do something similar: they carry an internal gadget called a "Season-Meter" that tracks temperatures over the preceding weeks or months to help determine ...
Phys.org / Why atmospheric nanoparticles grow at similar rates everywhere
Aerosols have a profound influence on air quality, human health, clouds and climate, but new particle formation in the atmosphere has remained a scientific conundrum. Large fractions of airborne fine particulate matter consist ...
Phys.org / Plant hormones may offer a way to balance crop yield and disease resistance
Growth or immune response? Higher organisms must constantly balance these two priorities. As in humans, hormones regulate this balance in plants. Researchers at the Technical University of Munich (TUM) have discovered a mechanism ...
Phys.org / Aboriginal artists painted giant ancestral beings as colonization arrived, study finds
Slithering across the ceiling of an Australian rock shelter is a giant snake with a crocodile-like head, razor-sharp teeth and a long tongue. It's more than 6 meters (20 feet) long, making it one of the largest Rainbow Serpent ...
Phys.org / Infection kills gut cells, while diet reshapes existing ones, fruit fly study finds
The intestines rely on different strategies to rebuild themselves in response to diet changes versus infections, according to a new Cornell study—a finding that can shed light on how gut health adapts to harsh conditions, ...
Phys.org / NASA's newest space telescope launches on a quest to explore the hidden universe
NASA's newest crown jewel blasted off Sunday to hunt for planets around other stars, explore secret dark energy and survey the cosmos like never before.
Phys.org / Hollow-core fiber platform could help different quantum technologies connect
Quantum technologies promise secure communication networks, powerful forms of computing and new sensing tools. One of the major challenges, however, is that different quantum systems often operate at different wavelengths ...
Phys.org / 'Cut-to-fuse' strategy: A new route for molecular skeletal editing
Restructuring a molecule without rebuilding it from scratch is an increasingly important goal in modern organic chemistry. Skeletal editing is an approach that helps chemists explore new chemical structures and simplify the ...
Phys.org / The length of your online reviews may help scammers map your friends and target them
On the surface, posting online reviews looks like a win-win activity. It helps both businesses we like and people who might frequent them. But although posting reviews can benefit others, it can also put us all at risk, according ...
Phys.org / Tides can be mapped much more locally using a new method based on satellite images
When high or low tide occurs, the water does not necessarily rise and fall uniformly along the entire coastline. In fact, the height of the tide in a bay can vary by up to one meter (3 feet) from one location to another just ...
