Phys.org / Molecular memory: How a mother's age echoes in her offspring's cells
In humans and many other animals, a mother's age can affect the physical and behavioral characteristics of the next generation. Scientists call these changes maternal age effects, and while they are widespread across the ...
Phys.org / Dark matter may be gravitationally lensing a likely source of cosmic neutrinos
Astronomers have discovered that the jet of a distant blazar has been gravitationally lensed by an unseen source of dark matter. Led by Silke Britzen at the Max Planck Institute for Radio Astronomy in Germany, the team's ...
Phys.org / Amber fossil reveals firefly relative with unprecedented antennae
Insects rely on a wide range of strategies to sense their surroundings and communicate with their peers. Fireflies (Lampyridae) and some related beetles are known for their ability to produce visible light through chemical ...
Phys.org / First pair of feeding supermassive black holes found in a Green Pea galaxy
Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-forming system. X-ray observations ...
Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Phys.org / 35-year monitoring study clarifies ecological forces behind Lyme disease risk
Tick-borne diseases are on the rise in the United States. Lyme disease is the most commonly reported, with nearly half a million people diagnosed each year. Caused by the bacterium Borrelia burgdorferi, it is most often spread ...
Phys.org / Last common ancestor of humans and chimpanzees could have been a vertical climber, no matter its feet
New research suggests that no matter what we eventually determine the last common ancestor of humans and chimpanzees to be, we'll learn it was a primate that climbed trees.
Phys.org / Immune cells have a 'sense of touch,' scientists discover
Scientists have long believed that tissue-resident memory T cells—which remain in tissues after an infection has cleared and respond rapidly if the threat returns—are shaped primarily by biochemical signals. A McGill University–led ...
Phys.org / Unlocking Gondwana's 120-million-year archive: Karoo record refines timing of extinctions and climate upheavals
A new review led by professor Emese Bordy at the University of Cape Town (UCT) Department of Geological Sciences brings together more than two decades of research on the Karoo Supergroup, revealing how scientific understanding ...
Phys.org / Physicists predict a new form of quantum matter that holds itself together
Researchers at Monash University have predicted a new type of quantum matter that challenges decades of thinking about how ultracold particles behave. The paper, "Quantum droplets in a resonant Bose-Fermi mixture," is published ...
Phys.org / Mega-Earth GJ 523b is 23 times as massive as our planet—but only 2.5 times as wide
It's nearly 170 million years old. It's more than 2.5 times the size of Earth. And it's the first exoplanet discovered and cataloged by researchers with the Wisconsin Center for Origins Research (WiCOR).
Phys.org / Three photons at once beat the standard photon test
Physicists at the University of Twente have improved the standard test for the quality of individual particles of light. By letting three photons interfere at the same time instead of two, they draw more information from ...
