Phys.org / Oldest known lizard ancestor discovered in England
Scientists announced Wednesday they have discovered the oldest-known member of the lizard family in southwest England, a tiny creature that used its surprisingly large teeth to hunt cockroaches 242 million years ago.
Phys.org / Atomic-level engineering enables new alloys that won't break in extreme cold
Navigating the extreme cold of deep space or handling super-chilled liquid fuels here on Earth requires materials that won't break. Most metals become brittle and fracture at such low temperatures. However, new research is ...
Phys.org / New metrics indicate habitat fragmentation has increased in over half the world's forests over the last 20 years
Deforestation is a well-known issue affecting biodiversity and carbon storage, but the fragmentation of forests is also a driving factor in the reduction of the world's biodiversity and carbon-storing abilities.
Phys.org / Study finds exoplanet TRAPPIST-1e is unlikely to have a Venus- or Mars-like atmosphere
In the search for habitable exoplanets, atmospheric conditions play a key role in determining if a planet can sustain liquid water. Suitable candidates often sit in the "Goldilocks zone," a distance that is neither too close ...
Phys.org / Q&A: New DNA techniques reveal unseen soil bacteria and antibiotic candidates
Bacteria have long been a key source of lifesaving antibiotics, but most species cannot be grown in the lab—leaving their therapeutic potential untapped even as multidrug resistance becomes an increasingly urgent threat.
Phys.org / The exoplanet TRAPPIST-1 e takes its turn in the JWST's spotlight
When the JWST finally began its long-awaited science operations in July 2022, there was a long list of targets awaiting its attention. Scientists compete for observing time by submitting proposals, and for every nine submitted ...
Phys.org / A pollution paradox: Wildfires in the western United States may improve air quality
Climate change is driving more frequent and more intense wildfires around the world, including in the United States. These huge blazes cause a range of problems that affect health, the environment, property and the economy. ...
Phys.org / Want to hear dinosaurs 'sing'? These instruments bring prehistory back to life
The roar of a T. rex, made iconic by Jurassic Park, has become the soundtrack of prehistory.
Phys.org / Saturday Citations: A mechanism for liver failure; LIGO black hole kick observed; primordial black hole explosions
This week, researchers reported on a new biopsy tool that can detect HPV-associated head and neck cancer up to 10 years before symptoms appear. Researchers developed a process to transform two-dimensional paintings into full-color, ...
Phys.org / Discovery of new moon or ring system orbiting mysterious distant planet Quaoar
Astronomers have discovered what they think may be another moon orbiting a distant dwarf planet called Quaoar. This small, icy, egg-shaped planet in the far reaches of our solar system, beyond Neptune, is already known to ...
Phys.org / Mini microscope enables real-time 3D brain imaging in freely moving mice
Researchers at the University of California, Davis, have created a miniaturized microscope for real-time, high-resolution, noninvasive imaging of brain activity in mice. The device is a significant step toward revolutionizing ...
Phys.org / Cheese cave fungi reveal how genetic mutations drive rapid evolutionary change
Many scientific discoveries are serendipitous—the result of chance. Seeing evolution in action in a cheese cave turned out to be exactly that for Benjamin Wolfe, associate professor of biology, and his colleagues.
