Phys.org / Ultrafast X-ray flashes partially reverse the damage they cause, enabling brighter, more accurate imaging
The interaction between X-rays and matter can be actively controlled, according to an international research team led by the University of Hamburg and SLAC National Accelerator Laboratory that has succeeded in producing bright ...
Phys.org / Ten viral genome regions may explain why deadly chicken virus evades vaccines
A highly contagious herpes virus causes Marek's disease, a deadly illness that mainly infects chickens. While it does not make people sick, the virus causes tumors and paralysis in chickens and, if unchecked, can spread rapidly ...
Phys.org / Over 100 South American lakes could become climate-change early-warning observatories
More than 100 shallow lakes stretching over 1,000 kilometers (620 miles) along the Atlantic coast of southern Brazil and Uruguay could become one of the world's most important natural laboratories for understanding how climate ...
Phys.org / Scientists watch, molecule by molecule, as cell helpers rescue problem proteins
University of Wollongong (UOW) scientists have uncovered, for the first time, exactly how two of the cell's "helper" proteins operate as a rescue crew for misfolded proteins, a discovery that sheds new light on the molecular ...
Phys.org / How the brain helps protect fertility from heat-induced damage
As global temperatures continue to rise, scientists are racing to understand why heat so profoundly threatens fertility across the animal kingdom. A new study from the Hebrew University of Jerusalem and collaborators has ...
Phys.org / Genetic analysis identifies a distinct Risso's dolphin population around British Isles
Risso's dolphins around the British Isles are part of a single population—genetically distinct from those elsewhere in the Atlantic, new research shows. Scientists studied the DNA of dolphins that stranded in England, Scotland ...
Phys.org / How simple amber lights could make nights safer for insects
Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources ...
Phys.org / Laid to rest with care: Ancient infants, perhaps twins, found in 1,200-year-old latrine
More than 1,000 years ago, two babies were tucked away in an abandoned Roman toilet channel. Yet, despite what the location suggests, they were cherished, not discarded.
Phys.org / Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July ...
Phys.org / DESI side project reveals the spectra of disintegrated exoplanets
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while ...
Phys.org / Newly unearthed mechanism that helps plants 'feel full' could help crops use fertilizer more efficiently
New York University researchers have pinpointed the molecular players responsible for plants "feeling full" once they've taken up enough nitrogen—a finding that could help scientists develop plants that absorb more nitrogen ...
Phys.org / New microscopy method achieves angstrom-scale localization precision with one laser
Researchers in the lab of Sam Peng, the Pfizer Inc.–Gerald Laubach Career Development Assistant Professor of Chemistry at MIT and a core institute member of the Broad Institute of MIT and Harvard, have developed a super-resolution ...
