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 ...
Phys.org / Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau
A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the ...
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 / 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 / As RSV evolves, a two‑pronged antibody cocktail aims to stay ahead
Scientists in China have developed a two-antibody cocktail to treat respiratory syncytial virus, or RSV, that in laboratory studies prevented the virus from developing drug resistance—a persistent problem with current therapies ...
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 ...
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 / 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 ...
Dialog / Scientists build arsenic-lined crystal pore framework to boost rhodium catalyst performance
Rhodium is one of the most powerful catalytic metals known to chemistry. Small amounts of it can drive reactions that produce millions of tons of useful chemicals every year. But getting rhodium to work well—quickly, selectively, ...
Phys.org / Advanced mirror technology now powers a breakthrough X-ray telescope
Scientists in Japan have developed a high-resolution X-ray telescope sharp enough to distinguish an object just 3.5 mm wide from one kilometer away, by combining precision mirror-making technology with space astronomy. To ...
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 / 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 ...
