Tech Xplore / AI models can fake visual understanding of images that don't exist
It wasn't long ago that news headlines claimed that AI might soon assist radiologists in interpreting X-rays of broken bones and analyzing mammograms. We are still far from the destination, as a new study has brought to light ...
Phys.org / Astronomers find the strongest evidence yet for the universe's first stars
For decades, astronomers were only able to study the universe's very first stars using theoretical models. Now, observations from the James Webb Space Telescope (JWST) have revealed what may be the most compelling evidence ...
Medical Xpress / Immune cells in the nose slow influenza virus, study finds
A new study from the University of Gothenburg may help guide the development of better influenza vaccines. Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may ...
Phys.org / Scientists spot a solar flare with surprising spectral behavior
On August 19, 2022, solar astronomers using the Daniel K. Inouye Solar Telescope (DKIST) on the Hawaiian island of Maui caught the fading remnants of a C-class solar flare. Their observations showed something unusual: very ...
Phys.org / Ancient Korean DNA reveals marriages between closely related individuals
DNA studies of 1,500-year-old skeletons have revealed that ancient Koreans lived in tightly knit family networks where marrying close relatives was common in some cases, from powerful elites to individuals chosen for human ...
Medical Xpress / Nerve growth factor alone triggers osteoarthritis-like joint changes in healthy mice
Nerve growth factor (NGF) is a specialized protein, also called a neurotrophin, that is critical for the development and survival of nerves responsible for our senses and the body's fight-or-flight response. While the presence ...
Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
Medical Xpress / Water contaminated with 'forever chemicals' during pregnancy linked to an increased risk of childhood asthma
PFAS, or per- and polyfluoroalkyl substances, are a group of human-made chemicals found in everything from food packaging to firefighting foam. Often called "forever chemicals" due to their persistence in the environment, ...
Phys.org / A matter of taste: Did Neanderthals really like sapiens women?
Going by the headlines, the matter seems to be settled. El País announces that Neanderthal men "chose" sapiens women. Science journal speaks of a "partner preference." National Geographic is already imagining the "Romeos" ...
Tech Xplore / One tiny diode could shrink image sensors by adding memory and processing
P-n diodes are two-terminal devices that consist of two types of semiconductor materials (i.e., a p-type and an n-type material) joined together. These components allow electric current to only move in one direction, which ...
Phys.org / Electrode technology achieves 86% efficiency for converting CO₂ into plastic precursors
In the process of converting carbon dioxide into useful chemicals such as ethylene—a key precursor for plastics—a major challenge has been the flooding of electrodes, where electrolyte penetrates the electrode structure and ...
Medical Xpress / Art films boost creative thinking in nearly 500 viewers, experiment suggests
A new study offers some of the strongest evidence yet that viewing art doesn't just move us emotionally—it changes how we think. Researchers at UC Santa Barbara found that people who viewed artistic film shorts showed measurable ...
