Phys.org / Gamma-ray signal could be long awaited evidence for WIMPs
Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never ...
Phys.org / Archaeologists investigate a feared young woman's 17th century vampiric grave in Poland
In 2022, excavations at a cemetery in Pień, Poland, led by researchers from the Institute of Archaeology at Nicolaus Copernicus University, led to a mysterious discovery. In what they call Grave 75, they uncovered the 400-year-old ...
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 / Bright people know more about wine: How higher intelligence is reflected in deep domain knowledge
Intelligent people tend to perform better at school and at work, as numerous studies have shown. But what happens in domains where incentives such as good grades or financial rewards don't apply and where socioeconomic status ...
Phys.org / JWST reveals a race against time for forming planets
Planets form from disks of gas and dust around young stars, but the gas needed for growth does not last forever. New observations from NASA's James Webb Space Telescope (JWST) now offer a new view of how this gas escapes ...
Phys.org / Sound waves do double duty, carrying and protecting quantum information
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a promising new way to protect fragile quantum information using nothing but mechanical vibrations—essentially ...
Dialog / Hydroclimate whiplash damages California's tallest redwoods after years of drought
Tall trees are generally associated with high-biomass forests. This is particularly true for forests dominated by Sequoia sempervirens (hereafter redwood), the world's tallest tree species. Extreme decay resistance, the ability ...
Phys.org / A near extinct plant in Galápagos is now recovering
A 30-year conservation effort has helped the critically endangered Galápagos snapdragon (Galvezia leucantha subsp. leucantha) recover from just six individuals to a small, carefully tended wild population. Following tireless ...
Phys.org / Machine learning method uncovers hidden patterns in DNA methylation
In a study recently published in Nature Communications, researchers from Berlin, Potsdam, and Jena present a new method for analyzing the epigenome. The machine-learning method identifies differentially methylated DNA regions ...
