Science X / How a brainless sea blob still 'feels' touch and crawls away in seconds without nerves or muscles
For a flat sea creature just a few millimeters across, a gentle poke is instantly recognized as danger. Trichoplax adhaerens—a translucent blob with no head, brain or muscles—scuttles away in seconds when touched. Imagine ...
Tech Xplore / New study shows one in seven people have been victims of sextortion—and AI is making it worse
The Australian eSafety Commissioner recently launched a new campaign to raise awareness of sexual extortion, or "sextortion." Targeted primarily at men, the campaign features AI-generated videos of attractive women attempting ...
Phys.org / Mars-like conditions fail to kill some Earth pathogens, experiments suggest
Microorganisms from our planet could survive on celestial bodies where water is present, such as Mars. That is the conclusion of Ph.D. candidate Tommaso Zaccaria after experiments with simulated space conditions. Our immune ...
Medical Xpress / Performing under pressure? For athletes, it depends on 3 key things
Why do some people seem to thrive under pressure while others seem to fold or crumple?
Phys.org / NASA testing advanced capabilities for moon, Mars rovers
On a bleak stretch of the Colorado Desert in Southern California, a compact four-wheeled rover recently trundled 16 miles (26 kilometers) with minimal intervention from the team of engineers trailing it. Called ERNEST (Exploration ...
Phys.org / Why just sharing a stick while walking can significantly improve balance
Could the secret to preventing dangerous falls be surprisingly simple? For older adults, these unexpected tumbles are a leading cause of injury, affecting roughly 1 in 4 people 65 and older each year. What if the key isn't ...
Phys.org / Crane pair dances follow hidden rules, with performances revealing partner-driven timing
Animal pairs engage in mutual signaling by simultaneously performing a diverse repertoire of behaviors. A famous example is the sophisticated dance (mutual displays) performed by bird pairs.
Phys.org / New nanotube membranes reveal unusually fast lithium-ion transport
Researchers have developed a novel class of nanotube membranes that enable ultrafast ion transport. The findings open new pathways for high-efficiency clean energy generation, lithium recovery and molecular separation.
Phys.org / Can North America mine enough rare earth elements?
In the quest to create a robust supply chain of rare earth elements necessary for the clean energy revolution and everyday modern conveniences, North America has enough deposits of sufficient quality to begin looking in its ...
Medical Xpress / Neuroimmune abnormalities may play a key role in fibromyalgia
Fibromyalgia is a complex disorder characterized primarily by chronic widespread pain, fatigue and other physical and cognitive symptoms. Although it affects millions of people worldwide, the underlying biological mechanisms ...
Phys.org / 'Geriatric' butterfly species lives nearly three times as long as their relatives
A tropical butterfly has evolved an ingenious anti-aging strategy by delaying the aging process, enabling it to live far longer than its closest relatives, according to a new University of Bristol-led study published in Nature ...
Phys.org / White roofs and urban parks reduce heat in cities, but do not offset extreme global warming
The implementation of reflective white roofs and new urban parks can significantly reduce temperatures in cities and decrease population vulnerability to heat waves, although these measures are not sufficient to counteract ...
