Phys.org / Analog gravity advance offers new insights into Hawking radiation from black holes
Hawking radiation is a form of radiation emitted by black holes, as theoretically predicted by Stephen Hawking. It suggests that black holes do not merely swallow matter—as had previously been assumed—but also emit very faint ...
Phys.org / Quantum semiconductor design could expand search for dark matter
Dark matter accounts for 85% of the matter in the universe, but scientists still do not know what it is made of. A study, published in Physical Review Letters, by Rice University researchers proposes a detector design that ...
Phys.org / Dynamic black holes may obey Hawking-style thermodynamics with an alternative entropy measure
Of the known things in the universe, black holes are among the most extreme. They pack huge amounts of mass densely into a small area, producing gravity that is so strong that even light cannot escape. To describe their properties, ...
Phys.org / A holoparasitic plant replaces its own genes with host DNA to survive
All living organisms are known to inherit genes, DNA sequences that contain instructions for producing specific proteins and performing biological functions, from their parents. In some cases, however, genes can also shift ...
Phys.org / Swimming crab trapped in plastic bottle survives two months at sea
How did a large crab end up trapped inside a plastic bottle with an opening smaller than its body? Hiroshima University researchers investigated this unusual marine mystery, revealing a lesser-known impact of marine plastic ...
Phys.org / Airborne AI spots underwater munitions in shallow seas with high precision
A new airborne imaging approach can reliably detect unexploded weapons that lie in shallow coastal waters and remain an ongoing hazard to public safety, marine ecosystems and infrastructure worldwide. By combining advanced ...
Phys.org / Scientists uncover why Antarctica became engulfed by ice millions of years before the Arctic
Scientists have uncovered why Antarctica became engulfed by ice millions of years before the Arctic. The international research, published in Science, helps solve one of climate science's longest-standing puzzles: how a vast ...
Phys.org / Zero-waste plastic and color recycling: The end of colored plastic downgrading could be near
In the world of market competition, having the best and brightest package could send company sales into the millions. On the other hand, the amount of colored plastic waste increases, adding to the growing challenge of recycling ...
Phys.org / More Canadian than the beaver? Scientists discover a western toad found only in Canada
The beaver and moose may be enduring symbols of Canadian wildlife, but neither is uniquely Canadian from a genetic perspective. But a team of researchers from the University of Ottawa has now discovered something rare: a ...
Phys.org / Ecological factors, not social behavior, explain brain size in cephalopods
Octopuses, squid and cuttlefish may have evolved large brains because of the challenges posed by their environments rather than the demands of social life, according to a new study published in iScience today.
Phys.org / Nanozymes map nanoparticle routes inside live cells without genetic engineering
Nanoparticles are widely used in medicine to deliver drugs, genes or imaging agents to specific parts of the body. Once a nanoparticle reaches a cell, however, many things can happen—it can reach its target, be degraded, ...
Phys.org / How giant tropical trees transport water 70 meters to stay as drought-resilient as smaller trees
The giant trees of tropical forests are important allies in the fight against climate change because of their ability to store carbon, yet they are still poorly understood by science. However, a study published in the journal ...
