Phys.org / How H5N1 bird flu hid unrecognized for weeks in dairy cattle
When H5N1 bird flu first began infecting U.S. cattle in early 2024, diagnosis was elusive because, in cows, the disease looked completely different. Instead of affecting the lungs, as H5N1 does in other mammalian species, ...
Phys.org / Stressed-out soil bacteria adapt to environmental conditions
A new study from Caltech demonstrates that soil bacteria can adapt under stress, particularly when a key nutrient, phosphorus, is running low in their environment. The work is important for understanding the complex relationships ...
Phys.org / Unearthed bathhouse reveals a thriving Roman Nijmegen: 'The Romans did not regard this city as a backwater'
Excavations in Nijmegen-West have uncovered large sections of a Roman bathhouse. It is the largest bathhouse complex from the Roman period in the Netherlands. Radboud researcher Stephan Mols can often be found at the excavation ...
Phys.org / Microbial partners may help maize and sorghum respond to higher temperatures
New research suggests the microbiome near the surface of a plant's roots, known as the rhizosphere microbiome, may play a role in helping crops respond to heat stress.
Phys.org / New technique sharpens predictions of metal alloy behavior by capturing subtle atomic patterns
Companies working at the frontier of aerospace, energy and computing are constantly looking for new materials to improve performance. But in order to understand how those materials will actually behave once they're inside ...
Phys.org / Arabian Sea humpback whale's long-distance trip further highlights species' unique ecology
Off Oman's coast lives a small population of just over 80 Arabian Sea humpback whales (ASHWs). They are classified as endangered and are thought to be the only humpback whale population that doesn't undertake seasonal migrations ...
Phys.org / Shining light into unhatched eggs could allow for chicken 'gender reveals'
Scientists have demonstrated a noninvasive technique that uses light to reveal the hidden contents of chicken eggs, potentially helping to curb the meat industry's practice of killing billions of male chicks at birth. The ...
Phys.org / Molecular simulations uncover why water nanodrops spread thin on hydrophilic surfaces
Why does water roll off a duck's back but spread on clean glass? For macroscopic (millimeter-scale) drops, this behavior can be explained using continuum theory. However, when nanoscale (10–9 mm) droplets spread on surfaces, ...
Phys.org / Ripple-like rings of the 'Bullseye galaxy' could be explained by dark matter
Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the Bullseye galaxy, could have emerged through the quantum behavior of particles of dark matter. Through ...
Phys.org / Hidden electric space waves are quietly cleaning Earth's 'killer' electrons
High above our heads, a silent battle is unfolding within Earth's magnetic shield. For decades, scientists have tracked "killer electrons"—ultrafast particles capable of piercing satellite armor and endangering astronauts ...
Phys.org / Fossilized babies of ancient crocodile-like predators uproot understanding of how animals adapted to the land
Life on our planet began in the water. Eventually, one branch of the fish family tree developed legs and came up on land. These early four-legged animals, the tetrapods, were the forebears of today's mammals, birds, reptiles ...
Phys.org / Pigeons' eyes are almost perfectly still when they're flying, study finds
When pigeons are flying through the air, they lock their eyes in a near-fixed position instead of moving them around. Researchers from Harvard University discovered this after attaching a lightweight rig of cameras and mirrors ...
