Phys.org / Cosmic predators: How supermassive black holes slow star growth in nearby galaxies
Intense radiation emitted by active supermassive black holes—thought to reside at the center of most, if not all, galaxies—can slow star growth not just in their host galaxy, but also in galaxies millions of light-years ...
Phys.org / Antarctic warming is altering atmospheric stability: New evidence from the 1950s to the present
A new study published in the Journal of Climate reveals how surface warming in Antarctica, particularly over the Antarctic Peninsula, is significantly altering the stability of the lowest layers of the atmosphere.
Phys.org / Exposing a hidden anchor for HIV replication
The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it. More than 40 million people worldwide live with AIDS because of this virus, and treatments must continually ...
Phys.org / Simplifying quantum simulations—symmetry can cut computational effort by several orders of magnitude
Quantum computer research is advancing at a rapid pace. Today's devices, however, still have significant limitations: For example, the length of a quantum computation is severely limited—that is, the number of possible ...
Phys.org / Eclipse research finds turbulent times in the sun's corona
Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses. Drawing on more than ...
Phys.org / Ultrasound-jiggled nanobubbles can crack cancer's collagen 'fortress'
Researchers at Case Western Reserve University have discovered a way to breach one of cancer's most stubborn defenses: the impenetrable fortress that solid tumors build around themselves.
Phys.org / Quantum-level effects in biology: Weak magnetic fields and isotopes can alter cell protein structures
A novel method to manipulate the inner structure of cells connects several scientific fields and could represent a significant step in the treatment of neurodegenerative diseases, such as Alzheimer's and Parkinson's disease. ...
Phys.org / As glaciers retreat, Greenland seals may lose key feeding hotspots
Studying foraging behavior in marine mammals is especially difficult. Unlike terrestrial animals, which can often be directly observed, marine mammals feed underwater and across vast, remote areas, making it challenging to ...
Phys.org / The making of doting dads may involve a specific gene
Male caregiving is rare. Of the nearly 6,000 mammalian species, fewer than 5% of fathers stick around to raise their own young. Most are even instinctively hostile. Even among the mammals that pitch in with caregiving duties, ...
Phys.org / An 'electrical' circadian clock balances growth between shoots and roots
Plants don't just respond to light and water, they also run on an internal daily timekeeper known as the circadian clock. Researchers have now discovered that the plant circadian clock can regulate electrochemical signals ...
Phys.org / Homes in the fire zone: Why wildland-urban blazes create significantly more air pollution
A research team led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) has published a foundational inventory of emissions produced by structures destroyed by fires in the wildland-urban ...
Phys.org / Does the motion of DNA influence its activity?
How does our DNA store the massive amount of information needed to build a human being? And what happens when it's stored incorrectly? Jesse Dixon, MD, Ph.D., has spent years studying the way this genome is folded in 3D space—knowing ...
