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 ...
Phys.org / Probability underlies much of the modern world—an engineering professor explains how it actually works
Probability underpins AI, cryptography and statistics. However, as the philosopher Bertrand Russell said, "Probability is the most important concept in modern science, especially as nobody has the slightest notion what it ...
Phys.org / 6 planets will parade across the night sky at the end of February
Six planets are linking up in the sky at the end of February, and most will be visible to the naked eye.
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" ...
Medical Xpress / First evidence of a 'critical priority' fungal pathogen becoming more deadly when co-infected with tuberculosis
Cryptococcus neoformans is one of four fungi classified as "critical priority" on the WHO's Fungal Pathogens Priority List, which was published in October 2022 following decades of research and calls for fungal pathogens ...
Phys.org / How to improve the performance of qubits: Super-fast fluctuation detection achieved
Using commercially available technology and innovative methods, researchers at NBI have pushed the limits of how fast you can detect changes in the sensitive quantum states in the qubit. Their work allows researchers to follow ...
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. ...
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 ...
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 / 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 / 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 / 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 ...
