Medical Xpress / Mapping how mental health risks emerge in AI chatbot conversations
Scientists at UCL have developed a framework for stress-testing how AI chatbots respond to vulnerable users, helping researchers identify weaknesses and test ways to make mental health interactions safer.
Phys.org / Chinese label once tied to Boston Tea Party reveals 19th-century Pacific trade
When MIT historian Tristan Brown first examined a Chinese tea chest label displayed as a relic of the Boston Tea Party, he had no reason to doubt its story.
Phys.org / Rescued platypuses quickly return to normal lives after five months in captivity
Platypuses rescued during a severe drought quickly returned to their old routines after being released back into the wild, suggesting emergency rescues can help protect vulnerable populations.
Phys.org / Toxoplasma parasite reveals an unusual strategy for surviving crowded environments in infected cells
Toxoplasma gondii, or Toxoplasma, is a parasite that infects hundreds of millions of people around the world. Although cases are often mild, it can cause severe symptoms in people with weakened immune systems and developing ...
Tech Xplore / A new class of metals could transform Africa's clean energy economy—scientists explain
For centuries, useful metals have been developed by starting with one core element and adding small amounts of other elements. Steel, for example, is composed primarily of iron; carbon is added in varied amounts to produce ...
Medical Xpress / Socializing: A prescription for healthier brain aging
Imagine heading to a doctor's office for memory problems and getting a prescription to hang out with friends.
Phys.org / How to spot the Perseid meteor shower, a summer light show that promises to dazzle
The Perseid summer light show is back—and viewing conditions are especially promising for the Northern Hemisphere.
Phys.org / Perceived naturalness emerges as key driver of public support for climate technology
From nuclear energy to lab-grown meat, the list of effective but unpopular climate solutions is long. A new University of Colorado Boulder study sheds light on why people reject or accept some proposed sustainability technologies: ...
Tech Xplore / From 'learning' to 'thinking,' AI language has long carried double meanings
Organizations can describe artificial intelligence using familiar words like "thinking," "writing" and "learning." But according to Carnegie Mellon University historian Christopher Phillips, those terms may tell us as much ...
Phys.org / Using salt to drive drug-carrying particles deeper into difficult-to-treat biofilms
Biofilms—bacterial communities encased in a sticky, polymer-rich matrix—can be difficult to treat because that matrix slows antibiotics and drug-carrying particles. With help from salt, though, Yale researchers have found ...
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 / 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. ...
