Chinese users of AI-powered companion bots have bade heart-rending farewells to their virtual buddies as national regulations took effect Wednesday, aimed at curbing the risk of emotional dependency.
Medical Xpress / Study shows a blood test can help identify healthy people at high risk for Alzheimer's disease
A blood test may predict if apparently healthy older adults are likely to develop Alzheimer's symptoms in the next five or 10 years, researchers reported Wednesday.
Medical Xpress / The new malaria vaccine helps in Africa but faces a test: Completing all 4 doses
Rain had turned the dirt road into thick mud, but Mabel Djoumessi kept walking with her 9-month-old son, Kenfack, strapped to her back. His malaria vaccination appointment at a clinic in central Cameroon was too important ...
Phys.org / Elephants turn footsteps into messages through ground and skull vibrations
Elephants can communicate with other elephants across distances of up to five kilometers (3 miles) by producing sounds that travel through the air. However, they have a second way of sending signals: seismic waves traveling ...
Medical Xpress / Brain-computer training sharpens detection of tiny movement errors in five days
The brain uses visual cues to coordinate muscle movement. When motor commands and sensory feedback are out of alignment, visuo-motor errors occur. Rapid perception of these errors allows for correction, which is important ...
Medical Xpress / Blood-based test can predict risk of developing symptoms of Alzheimer's up to a decade early
A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged about the extent to which such tests can accurately predict whether a cognitively healthy individual ...
Phys.org / A new smart coating could improve the cleanup of nuclear wastewater
Scientists in China have developed a smart coating that could make it easier to remove tritium (a radioactive form of hydrogen) from nuclear power plant wastewater.
Phys.org / Frame-dragging observations validate Einstein yet again
More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio ...
Tech Xplore / Daydreaming algorithm helps AI remember what matters
During the day, our brain acquires new memories; at night, during sleep, it consolidates the important ones and eliminates the useless ones. A similar principle has been applied to Hopfield networks, one of the classic models ...
Phys.org / Why we may still be choosing our friends like it's the Stone Age
Choosing friends may involve more than clicking with others who share our interests or outlooks. According to new research, people may select friends based on traits that made them valuable survival partners in our evolutionary ...
Phys.org / Low carbon dioxide levels improve microbial production of biodegradable plastic
In an innovative gas fermentation process, reducing the concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic poly[(R)-3-hydroxybutyrate]. Researchers found that ...
Dialog / Ocean acidification emerging as a planetary signal linking today's carbon emissions to Earth's deep-time memory
When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...
