Phys.org / Setting limits on phase transitions in the dark energy era
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / The hidden physics behind the shape of rose thorns
Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
Phys.org / Using plutonium to probe the universe: Magneto‑ν experiment advances dark matter and neutrino research
Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale structure of the cosmos. In an effort to uncover the composition of this hidden mass, a team at Lawrence ...
Phys.org / Chemical physicists quantitatively model electron interactions in real quantum materials
A team of scientists from Caltech and Yale University has shown for the first time how to accurately quantify an important quantum phenomenon in metals, called the Kondo effect, for specific real materials. Unlike previous ...
Phys.org / Exact calculations sharpen view of atomic nuclei
Every high-energy nuclear collision leaves behind a trail of clues about the structure of atomic nuclei. Deciphering those clues, however, depends on the accuracy of the underlying theory. Physicists at Osaka Metropolitan ...
Phys.org / Rare medieval manuscript fragments reveal Guernsey's lost literary history
Seventeen medieval manuscript fragments have been identified in Guernsey with support from Kent manuscript expert Dr. David Rundle, offering an unprecedented insight into the island's literary and intellectual life during ...
Phys.org / Naked photobombing comet found in public image
Sometimes images are released before anyone realizes they have been photobombed, meaning something unexpected showed up in the background. A team of researchers found a naked photobombing comet in publicly available archival ...
Phys.org / Simulations reveal asymmetric diffusion of magnetic skyrmions through an off-center gate
Diffusion is a fundamental natural phenomenon that can be observed across a wide range of length and time scales. It plays a key role in many fields, including physics, biology and economics. In particular, asymmetric or ...
Phys.org / Forty forest drought experiments reveal trees show little physiological acclimation
Forests support much of the world's biodiversity and play a vital role in regulating Earth's climate, but they are increasingly exposed to drought. To understand the potential consequences of drought, a key question is whether ...
Phys.org / Could 12 inches of rain hit New York City? AI maps plausible rare storms
Can a city's seawall stand up to a blockbuster storm? Will a region's power grid hold against record-breaking heat? And can a town's firefighting resources contain a major wildfire?
