Phys.org / Rydberg atoms detect clear signals from a handheld radio
For the first time, a team of US researchers has used sensors containing highly excited Rydberg atoms to detect signals from an ordinary handheld radio. Through a careful approach to demodulating the incoming signals, Noah ...
Tech Xplore / How China is betting cheap AI will get the world hooked on its tech
Artificial intelligence (AI) is at a very Chinese time in its life. Recent moves from Chinese AI labs are throwing the dominance of American "frontier labs" such as Google and OpenAI into question.
Medical Xpress / Brain scans reveal why you can't resist a snack, even when you're full
Research from the University of East Anglia (UEA) may finally explain why we still reach for the cookie jar, even when we're full. A new study reveals that the human brain continues to respond to tempting food cues even after ...
Phys.org / Svalbard polar bears gained fat despite rapid Barents Sea ice loss
Their icy hunting grounds are rapidly shrinking, but polar bears in Norway's remote Svalbard archipelago have defied the odds by bulking up instead of wasting away, a study said Thursday.
Phys.org / Curiosity takes its closest look yet at Martian spiderwebs
In this age of Mars rovers, questions about the planet's ancient past have shifted. A growing body of evidence supports the idea that Mars was once warm and wet. Now researchers are focused on the timeline of the red planet's ...
Phys.org / The screech of peeling sticky tape conceals a rapid train of tiny shockwaves, ultrafast imaging shows
A new experiment has uncovered the mechanism responsible for the screeching sound made by peeling sticky tape. Using a combination of ultrafast imaging and synchronized acoustic recordings, Sigurdur Thoroddsen and colleagues ...
Tech Xplore / HFC electrolyte delivers energy-dense lithium battery that keeps running at −50 °C
A research team in China has developed an electrolyte using monofluorinated hydrofluorocarbon (HFC) solvents capable of achieving energy densities higher than 700 Wh kg−1 at room temperature and about 400 Wh kg−1 ...
Phys.org / Single-celled organism becomes multicellular via three different pathways
Some single-celled organisms are known to transition to multicellularity during their lifetimes, usually either by cloning themselves or when many similar cells come together to form a larger multicellular organism. A new ...
Phys.org / Why crowning the protein that makes jellyfish glow green as a model can help scientists streamline biology
Fruit flies, mice, zebrafish, yeast and the tiny worm C. elegans are model organisms that have carried modern biology on their backs.
Medical Xpress / Ivermectin was touted as a cure for COVID, now it's being tested for cancer. But what can it actually treat?
Ivermectin was originally celebrated as a revolutionary treatment for parasitic disease in humans and animals. It has since evolved into a focal point of misinformation and heated debate.
Medical Xpress / A blood marker could predict how people respond to antidepressants
Major depressive disorder (MDD) is among the most common psychiatric disorders, affecting approximately 330 million people worldwide. This disorder is characterized by persistent feelings of sadness, hopelessness, low motivation, ...
Phys.org / Drug discovery bottleneck? Cell-free platform screens peptides faster, even in harsh conditions
Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole (receptor) formed by a protein's three-dimensional structure and a molecule (ligand) that fits perfectly ...
