Phys.org / Oldest known asteroid impact on Earth dated to 3 billion years
Curtin University researchers have determined the most precise age yet for the oldest known impact crater on Earth, providing new insight into how meteorite strikes shaped the planet during its earliest history.
Phys.org / Physical pressure helps pathogenic P. aeruginosa survive antibiotic treatment
Pseudomonas aeruginosa is an opportunistic pathogen that can cause acute and chronic infections. Responsible for many hospital-acquired infections, it is also a major concern for people with cystic fibrosis, whose lungs are ...
Phys.org / Solid-state material turns visible light into high-energy UV at sunlight intensity, expanding solar energy potential
Two cups of warm water don't make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
Phys.org / Pterosaur wing tests suggest modern reconstructions miss major shape diversity
Pterosaurs, the first vertebrates to fly, would have had more diverse wing shapes than current scientific reconstructions suggest, according to new University of Bristol-led research. The study is published in the journal ...
Phys.org / Scientists create optical skyrmions using a two-century-old light phenomenon
Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, which are tiny, swirling ...
Phys.org / Pathway to high-fidelity quantum computing identified
Researchers from the University of Sydney, working with IBM, have identified and quantified important factors limiting the performance of quantum computers and demonstrated ways to overcome their impact.
Phys.org / People care more about being right than avoiding mistakes, study finds
Conventional wisdom says the best predictions are the ones that minimize mistakes, but new research suggests that is not necessarily how people see it. A study published in Management Science has found that when people make ...
Phys.org / Hubble details early galaxy transforming neighborhood 1.4 billion years after Big Bang
Astronomers using NASA's Hubble Space Telescope have found something they never expected—ultraviolet light from a galaxy that existed just 1.4 billion years after the Big Bang. That galaxy contains tightly clustered young ...
Phys.org / Wave-packet interferometry captures elusive dark excitons in organic superconductor
In a recent study, Manish Garg, independent group leader at Max Planck Institute for Solid State Research (MPI FKF), succeeded in probing the local properties of bright and dark excitons in the organic superconductor copper ...
Phys.org / Hidden dark force may slow cosmic structure growth, not speed it up
Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
Phys.org / How sperm whale vocal dialects evolve as they adopt new calls while still remembering the old
New research from the University of St. Andrews shows how sperm whale vocal dialects evolve as they adopt new calls while still remembering the old. An international team of researchers studying vocal dialects in the endangered ...
Phys.org / Espresso 'pucks' stop behaving predictably above certain pressures
When a physics student asked baristas at the Warsaw Coffee Conference what their biggest question for scientists was, the baristas said they wanted to know how to stop channeling during brewing.
