Phys.org / A robot that reads bacteria by touch, without staining or chemical labels
Fast identification of bacteria is important in health care, food safety, environmental monitoring and infection control. One of the most common first steps is gram classification, which separates bacteria into gram-positive ...
Phys.org / Tiny worms reveal backup circuits that keep survival reflexes from failing
A research team led by Professor Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong (HKU), in collaboration with scientists from Princeton University and Columbia University, has discovered ...
Phys.org / Intricate molecular mechanisms help bacteria evade immune detection
Northwestern Medicine scientists have identified a novel mechanism used by the bacteria responsible for gonorrhea to evade immune detection and achieve widespread infection, according to a recent study published in the Proceedings ...
Dialog / Dark energy flips its sign, but the Hubble tension refuses to budge
For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by ...
Phys.org / Darwin's 150‑year‑old hillside steps mystery may have a new answer from virtual grazing animals
Steep hillsides and mountainsides in many regions worldwide are often covered in characteristic step-like patterns, also known as terracettes. These repeating landforms have fascinated scientists for more than a century, ...
Phys.org / Why natural forests survive heat waves better than planted forests
When a record-breaking drought and heat wave swept across China's Yangtze River Basin in 2022, forests across the region faced an extreme test. The event provided a rare opportunity for researchers to test how different forests ...
Phys.org / New Jurassic dinosaur species identified in Thailand from a single bone
A new study published in Scientific Reports describes the identification of a new species of long-necked dinosaur found in the Phu Kradung Formation in Thailand. The team calls the dinosaur Uragasaurus kalasinensis and says ...
Phys.org / Hidden health risks found in New York City's free-roaming cats
Cats may be cute and adorable, but stray and feral cats can sometimes pose a risk to human health. Veterinary researchers have discovered that more than 50% of free-roaming cats in New York City carry parasites that could ...
Phys.org / Warm Jupiter exoplanet transiting a sun-like star discovered
An international team of astronomers reports the discovery of a new exoplanet orbiting a sunlike star as part of the Next Generation Transit Survey (NGTS). The newfound alien world, designated NGTS-39 b, is a Jupiter-sized ...
Phys.org / Bacteria turn dissolved uranium into stable compound in 130 days, study finds
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), together with Wismut GmbH and scientists from the University of Granada in Spain, have demonstrated for the first time that bacteria can convert uranium dissolved ...
Phys.org / Capturing the cosmic 'drift' before a star is born
Stars like our sun are formed from the collapse of stellar objects called prestellar cores, cold and dense concentrations of gas and dust held together by gravity. While many questions remain about the exact mechanisms of ...
Phys.org / Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans
A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land ...
