Phys.org / Astronomers map tangled, supersonic filaments in distant interstellar gas cloud
A team of astronomers has uncovered an unexpectedly complex and dynamic filamentary network within a very-high-velocity cloud (VHVC) in the Milky Way.
Phys.org / Dogs' TV viewing habits vary by personality
The way household dogs engage with TV may depend on their personalities, suggests research published in Scientific Reports. Excitable dogs were more likely to follow on-screen objects while fearful or anxious dogs were more ...
Phys.org / Historical and current population DNA reveals at least 12 species of rocket frogs, three of which already extinct
A group led by University of São Paulo (USP) researchers in Brazil has described a new genus of frogs, Dryadobates, also known as rocket frogs, which was previously considered a single species. The study was published in ...
Phys.org / Programmable DNA moiré superlattices: Expanding the material design space at the nanoscale
Researchers are creating new moiré materials at the nanometer scale using advanced DNA nanotechnology. DNA moiré superlattices form when two periodic DNA lattices are overlaid with a slight rotational twist or positional ...
Phys.org / How a triatomic molecule works off excess energy
A resonance effect can significantly affect how a three-atom molecule cools down when excited, RIKEN physicists have found. The study, published in Physical Review A, highlights the complexity of the relaxation dynamics of ...
Phys.org / The first dinosaurs might have been bigger than expected
An ancient leg bone uncovered in Africa might provide a step forward in understanding how dinosaurs and their close relatives evolved.
Phys.org / Butterflies that look alike, see alike: Research links rainforest light to butterfly vision evolution
Butterflies that independently evolved the same wing patterns have also evolved similar eyes and brains which are fine-tuned for vision in the shifting light of tropical rainforests, according to new research led by the University ...
Medical Xpress / Scientists zero in on cellular mechanism fueling drug-resistant cancers
The mystery of how cancers build up resistance mechanisms and evade the treatments that should have destroyed them is a hugely pressing question. Overcoming cancer treatment resistance—a phenomenon that contributes to as ...
Medical Xpress / Can ChatGPT diagnose you? New research suggests promise but reveals knowledge gaps and hallucination issues
When people worry that they're getting sick, they are increasingly turning to generative artificial intelligence like ChatGPT for a diagnosis. But how accurate are the answers that AI gives out?
Medical Xpress / Wednesday's child is not 'full of woe,' new study finds, debunking popular nursery rhyme
A University of York study has found no link between a child's day of birth and their destiny, reassuring parents that the age-old verse is simply "harmless fun."
Tech Xplore / Can AI really code? Study maps the roadblocks to autonomous software engineering
Imagine a future where artificial intelligence quietly shoulders the drudgery of software development: refactoring tangled code, migrating legacy systems, and hunting down race conditions, so that human engineers can devote ...
Medical Xpress / Researchers develop novel antibody-RNA therapy for resistant cancers
A specially engineered antibody that can accurately deliver RNA treatments into hard-to-reach and hard-to-treat tumors significantly improved survival and reduced tumor sizes in animal models, according to a study reported ...
