Scientists Uncover Surprising Reversal in Quantum Systems
Researchers have demonstrated how topological effects in an artificially constructed solid can be manipulated using magnetic fields to switch particle interactions on or off, potentially paving the way for advances in quantum technologies. Their experiments, which involved topological pumping in systems of cold fermionic potassium atoms trapped in laser-created lattices, showed that these systems can
Scientists uncover aurora-like radio emission above a sunspot
Scientists uncover prolonged radio emissions above a sunspot, akin to those previously seen in the polar regions of planets and certain stars, which may reshape our understanding of intense stellar radio bursts.

Paleontologists Uncover First Theropod Fossils in Chilean Patagonia
Paleontologists have described new specimens of theropods — a dinosaur group that includes both modern birds and their closest non-avian dinosaur relatives — from the Late Cretaceous deposits of the Río de las Chinas Valley in the Chilean portion of Patagonia. A time averaged artist’s interpretation of Patagonia during the Late Cretaceous epoch, about 66-78
Scientists uncover the largest crater on Earth under 100,000 years old
Home News (Image credit: NASA Earth Observatory image by Lauren Dauphin, using Landsat data from the U.S. Geological Survey.) A crescent-shaped crater in Northeast China holds the record as the largest impact crater on Earth that formed in the last 100,000 years.Prior to 2020, the only other impact crater ever discovered in China was found…
Scientists Uncover First Evidence of Respiratory Infection in a Dinosaur
Hypothetical life restoration of MOR 7029. Note that the pulmonary disease infecting this animal would not have been externally evident, but the probable pneumonia-like outward symptoms would have included coughing, labored breathing, nasal discharge, fever, and weight loss, among others.

Scientists Uncover How Water Temperature Affects the Shape of Melting Ice
These photographs show the different shapes of melted ice that form for cold (4 degrees C), intermediate (5.6 degrees C), and warmer (8 degrees C) temperatures of the ambient water. Credit: Courtesy of NYU’s Applied Mathematics Laboratory A team of mathematicians and physicists has discovered how ice formations are shaped by external forces, such as…
Scientists have pinpointed a gene that helps deadly E. coli bacteria evade antibiotics, potentially leading to better treatments for millions of people worldwide. The University of Queensland-led study found a particular form of the bacteria -- E. coli ST131 -- had a previously unnoticed gene that made it highly resistant to commonly prescribed antibiotics. Professor…
Scientists uncover new information about cellular death process, previously thought to be irreversible
A study published by researchers at the University of Illinois Chicago describes a new method for analyzing pyroptosis -- the process of cell death that is usually caused by infections and results in excess inflammation in the body -- and shows that process, long thought to be irreversible once initiated, can in fact be halted…
Scientists uncover the distribution and physiological role of planteose
Witchweed (Striga spp.) and broomrapes (Orobanche and Phelipanche spp.) are root parasitic weeds that inflict major losses in agriculture globally. Being obligate parasitic flowering plants in nature, they parasitize other autotrophic plants of agricultural importance. The plants are attached to their host by means of haustoria, which transfer nutrients from the host to the parasite.…
Astronomers uncover largest group of rogue planets yet
Rogue planets are elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Not many were known until now, but a team of astronomers, using data from several European Southern Observatory (ESO) telescopes and other facilities, have…
