Phys.org / Early snakes explored life underground, on land and at sea
Snakes are highly modified lizards, with more than 4,000 living species today. The origin of snakes has long been one of evolutionary biology's most debated questions. Their sparse fossil record has made it hard to pin down ...
Phys.org / New species of mountain horned dragon identified in Thailand's high-altitude forests
Scientists have described a new species of lizard from the high mountain forests of western Thailand and have given it a name straight out of an American fantasy drama television series: Acanthosaura syrax, named after Syrax, ...
Medical Xpress / Why a doctor saying 'it's normal' can backfire
A new study from the University of California San Diego Rady School of Management suggests that when physicians try to reassure patients by saying their symptoms are "normal," patients may infer that treatment isn't necessary—and ...
Phys.org / Real-time measurements reveal antiferromagnetic skyrmions move in line with an applied current
Skyrmions—essentially magnetic vortices—represent a promising approach in spintronics; in the future, they could serve as components in storage media or computers, potentially complementing established CMOS technologies. ...
Phys.org / Climate change could mean four extra hours of extreme heat on hot days
Hot days could gain more than four additional hours of extreme heat by the end of the 21st century under a high-emissions scenario, according to a modeling study published in Nature Climate Change. The findings show that ...
Medical Xpress / Patient-derived organoids reveal which breast tumors may resist standard therapies
Researchers at UC San Francisco have developed a new method to predict how different types of breast cancer will respond to treatment, using patient data from the I-SPY2 breast cancer trial and rapid testing on lab-grown ...
Phys.org / Fermentation emerges as key pathway for ammonium production beneath the Pearl River Delta
A study led by Professor Jimmy Jiujiu Jiao from the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU) and Professor Meng Li from Shenzhen University has identified microbial fermentation as the ...
Phys.org / Slow spin could explain why planets become hellish
Hundreds of Venus-like planets could soon help determine why some worlds become sweltering greenhouse hellscapes while others remain capable of supporting life. But before answering that question, scientists first need to ...
Phys.org / Ticklish spots are shared across cultures, but why they are ticklish is more complex than it seems
People from different cultural backgrounds are tickled in remarkably similar ways. They laugh, resist and are usually tickled by family members or friends. They are also ticklish in the same body regions. These are among ...
Phys.org / Mushroom behind 'tiny people' hallucinations identified
People in communities thousands of miles apart have described the same strange experience after eating a mysterious mushroom: vivid visions of tiny humans moving through and interacting with the physical world around them. ...
Medical Xpress / AI framework decodes how brain regions talk to one another
For decades, neuroscientists have been able to record which parts of the brain show increased electrical activity during a behavior, such as when we form a memory or make a decision. But scientists haven't been able to determine ...
Phys.org / Swarms of tiny robots remove microplastics from soil and water
Microplastics, which are plastic particles under 5 millimeters, are a major and growing threat in both soil and water. They damage soil fertility, disrupt nutrient cycling, harm aquatic and terrestrial life, and can move ...
