Phys.org / MeerKAT reveals three electron acceleration sites in one solar flare
Solar flares are the most explosive energy-release events in the solar corona, leading to intense particle acceleration, plasma heating and bulk plasma motions on short timescales. Core questions during solar flares remain ...
Phys.org / Tea compound boosts seaweed hydrogel strength fivefold, while tuning adhesion and breakdown
Could wound healing dressings adhere better, and could drug delivery patches become more sophisticated? A KAIST research team has developed a technology that leverages natural ingredients derived from plants to increase the ...
Phys.org / New dating of Spain's Sala Keimada rock art sanctuary reveals thousands of years of continuous use
The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) has participated in a study published in the Journal of Archaeological Science: Reports on Sala Keimada, one of the rock art sanctuaries in Cueva Palomera, ...
Phys.org / Why are sloths slow? It's in their DNA
Sloths are the slowest mammals on the planet, but living in dense jungles has made them notoriously difficult to study. For the first time, scientists have now sequenced and analyzed the two-toed sloth genome and revealed ...
Phys.org / Ancient ground squirrel droppings reveal Arctic's rich evolutionary history
Ground squirrel droppings, preserved for millennia in the Yukon's deep permafrost, have yielded an enormous amount of environmental DNA from dozens of species of plants, insects, microbes and large mammals, offering detailed ...
Phys.org / How climate shapes the meanings of words across languages
When English speakers say "rose" and Chinese speakers say "玫瑰," do they mean the same thing? A Peking University team led by Professor Bi Yanchao explored this question using word embeddings from 53 languages, behavioral ...
Phys.org / These underwater 'living pink rocks' help store carbon: Scientists just found four new species
Rhodoliths may look like small rocks on the seafloor, but they are actually living algae that create habitats for marine life and contribute to long-term carbon storage. A new study found that the deeper, low-light waters ...
Phys.org / Savanna chimpanzees use tools for capturing and feeding on army ants, study shows
Chimpanzees are the only great apes, apart from humans, that have adapted to living on savannas as well as in forests. However, it is not yet well understood how the harsh ecological conditions of the savanna—compared with ...
Phys.org / New 3D microscope technology captures high-resolution tissue images at a fraction of the cost
A team led by Raju Tomer, professor of biological sciences at Columbia University, has created a new design for microscopes and microscope lenses that could push 3D tissue imaging beyond state-of-the-art systems while drastically ...
Phys.org / 3D-printed nozzle array could streamline production of drug-delivery microparticles
MIT researchers have demonstrated a low-cost design for specialized electronic nozzles, called triaxial electrospray emitters, that could be used to manufacture time-release drug-delivery particles or self-healing materials ...
Phys.org / Some drugs 'fail' because of unrealistic testing conditions, scientists discover
A drug once dismissed as ineffective suddenly worked—when scientists tested it under more realistic conditions that mimic the human body. In this surprising new discovery, Northwestern University scientists uncovered a hidden ...
Phys.org / Koala population crash came before humans, genomic study reveals
A genomic study has reshaped our understanding of the evolutionary history of the koala (Phascolarctos cinereus), revealing the iconic Australian marsupial experienced a severe population decline around 100,000 years ago, ...
