Medical Xpress / A silent signaling network deep in the gut protects against inflammatory intestinal disorders, scientists find
Deep in the folds of the intestine, in microscopic pockets called crypts, a quiet surveillance system is always at work. Stem cells lining the gut wall are not just rebuilding tissue—they are listening and signaling. When ...
Tech Xplore / Jailbreaking the matrix: How researchers are bypassing AI guardrails to make them safer
A paper written by University of Florida Computer & Information Science & Engineering, or CISE, Professor Sumit Kumar Jha, Ph.D., contains so many science fiction terms, you'd be forgiven for thinking it's a Hollywood script: ...
Phys.org / Tomb more than 1,000 years old found in Panama
Archaeologists have discovered a tomb more than a thousand years old in Panama containing human remains alongside gold and ceramic artifacts, the lead researcher told AFP on Friday.
Phys.org / In sea urchin and salmon sperm, pH value regulates whether they remain immotile or swim
A study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn has shown that pH value is crucial for sperm motility in sea urchins and salmon. An increase in pH activates the enzyme adenylyl ...
Tech Xplore / AI model edits can leak sensitive data via update 'fingerprints'
Artificial intelligence (AI) systems are now widely used by millions of people worldwide, as tools to source information or tackle specific tasks more rapidly and efficiently. Today, some of the most used are large language ...
Medical Xpress / Oxytocin reverses anxiety-like behavior after three months of isolation in mice
Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. ...
Phys.org / Chemists synthesize first stable copper metallocene complex, closing a 70-year gap
Almost half a century ago, a remarkable molecule called metallocene took center stage in chemistry, earning Geoffrey Wilkinson and Ernst Otto Fischer the Nobel Prize. These organic compounds, made of a transition metal "sandwiched" ...
Phys.org / Can a chatbot be a co-author? AI helps crack a long-stalled gluon amplitude proof
Like many scientists, theoretical physicist Andrew Strominger was unimpressed with early attempts at probing ChatGPT, receiving clever-sounding answers that didn't stand up to scrutiny. So he was skeptical when a talented ...
Phys.org / Living tissues are shaped by self-propelled topological defects, biophysicists find
With a new mathematical model, a team of biophysicists has revealed fresh insights into how biological tissues are shaped by the active motion of structural imperfections known as "topological defects." Published in Physical ...
Phys.org / The persistence of gravitational wave memory
Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two neutron stars collide, they ...
Phys.org / Symbiotic bacteria in planthoppers break record for smallest non-organelle genome ever found
Many insects rely on heritable bacterial endosymbionts for essential nutrients that they cannot get through their diet. A new study, published in Nature Communications, indicates that the genomes of these symbiotic bacteria ...
Phys.org / The bouba-kiki effect: Baby chicks match sounds to shapes just like humans
When we hear certain sounds, our brains often pair them with specific shapes. For example, most people will associate a sharp-sounding word with a jagged, pointed shape, while a soft, rolling word is linked to something smooth ...
