Tech Xplore / When AI art has no author: Study finds generated images often can't be traced to training data
When an artificial intelligence image generator produces a portrait, whose work went into it? The question sits at the center of lawsuits, licensing deals and proposed regulations worldwide. Artists want credit. Companies ...
Medical Xpress / How loss of tumor suppressor drives ER+ breast cancer to metastasize to the bone
A Baylor College of Medicine-led team has uncovered how loss of tumor suppressor neurofibromin (NF1) in estrogen receptor-positive (ER+) breast cancer cells drives the cells' preference to metastasize to bone.
Phys.org / Loud snoring—simulation reveals the physical mechanism that keeps so many of us awake at night
Anyone who has had to share a room—or worse, a bed—with a loud snorer knows the effect unchecked snoring can have on sleep, sanity and emotional stability. An entire industry of products, technologies and treatments claims ...
Phys.org / Double spiral inside narwhal tusks may explain their resistance to bending
The narwhal's impressive tusk has long been the subject of myths. In the Middle Ages, they were sold as unicorn horns believed to possess magical powers. Now, an international team of researchers led by Aarhus University ...
Phys.org / AI prompts offer a new tool for mapping how emotion concepts relate
How similar are "joy" and "surprise"? Conversely, how far apart are "joy" and "sadness"? We naturally organize words that express emotions—such as "happy," "afraid," and "angry"—according to similarities and differences in ...
Phys.org / Small doses of caustic soda increase biogas production from banana waste
Low concentrations of caustic soda (sodium hydroxide, NaOH) are more efficient than high doses for preparing organic waste for biogas production. This finding increases methane production, reduces reagent consumption and, ...
Tech Xplore / The ultimate glow up: Flexible screens reach record brightness with redesigned electrolyte and electrodes
From a skin patch that changes color to flag abnormal blood sugar to a diver's sleeve display that stays readable underwater, the need for bright, flexible screens is growing, but no existing technology delivers the combination ...
Medical Xpress / Cannabis use linked to earlier onset of psychosis
Cannabis users develop psychosis an average of two-and-a-half years earlier than nonusers, a new meta-analysis by UNSW Sydney researchers shows. This earlier onset of psychosis becomes more pronounced with age, stretching ...
Medical Xpress / What is a thought made of? Scientists look beyond neurons—and raise new questions about AI
A familiar song can bring back a memory from decades ago. A particular smell can recall a person or place. And a frightening memory can trigger a simultaneous emotional and physical response almost instantly. Computers, too, ...
Tech Xplore / Laser de-icing system helps nuclear power plants improve maintenance of a critical safety system
University of South Florida engineers have developed an innovative laser-based technology that is helping nuclear power plants solve a complex maintenance challenge affecting a critical reactor safety system. After four years ...
Phys.org / 'Ecology of fear' can dramatically change the behavior of blue mussels
For a blue mussel, a good meal does not come entirely without risk. Blue mussels feed by filtering microscopic algae from seawater. But some unwelcome guests can slip in along with their food. Tiny parasite larvae can hitch ...
Medical Xpress / Heartbeats power a battery-free pacemaker designed to last a lifetime
Madison researchers have developed an implantable, battery-free pacemaker that's charged by a patient's heartbeat. The device has the potential to last an entire lifetime, reducing the risks and costs associated with replacing ...
