Phys.org / X-pinch plasma achieves radial proton acceleration for crisp imaging
Plasma pinches: From pursuits of nuclear fusion to an attractive point source of accelerated protons for proton radiography.
Phys.org / Astronomers dig deep to find tiny dangerous space debris
In a new study, published in the Journal of the Astronautical Sciences, Warwick researchers led an international effort to uncover some of the faintest debris in geosynchronous orbit ever observed, finding fragments as small ...
Phys.org / Why some glasses break suddenly while others deform smoothly
If a liquid is cooled slowly to its freezing point, it becomes a crystal in which the constituent particles are arranged in an ordered pattern. In contrast, when the liquid is cooled very quickly, the particles are unable ...
Phys.org / New deep-sea measurements show how the ocean floor forms
The first-known direct observations of a seafloor spreading event at a mid-ocean ridge in the Indian Ocean are presented in Nature. The observations offer insight into how new oceanic crust is created.
Phys.org / Space sensor could spot hidden nuclear weapons in orbit with 99% accuracy
In 2024, a U.S. government official warned that Russia could be developing a new satellite designed to carry nuclear weapons into space. The statement followed the launch of a suspicious Russian satellite into low-Earth orbit ...
Phys.org / New probe could help trace Alzheimer's-linked lipids one cell at a time
Cells sitting side by side in the same tissues are not identical. Each cell carries its own subtly different chemical signature—a hidden individuality that can reveal how diseases take root and spread. Now, researchers from ...
Phys.org / Primordial mini-moons may explain meteorite composition
A new Southwest Research Institute-led study proposes a solution to a longstanding puzzle in planetary science: What caused the concentration, assembly, and preservation of millimeter-sized, spherical mineral grains within ...
Phys.org / Hidden jet from a 'missing-link' black hole lights up the radio sky
Astronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have detected an extraordinary burst of radio light from a rare cosmic event in which an intermediate-mass black hole tears apart a star, revealing ...
Phys.org / Manganese risk in groundwater affects 200 million people, study shows
Manganese is an essential trace element. However, in excessive concentrations, the metal can cause health problems. Two Eawag researchers have now produced a global risk map for manganese in groundwater. Half of the world's ...
Phys.org / Ancient atmospheric oxygen found in iron ore deposits
How do some of geology's most mysterious iron ore deposits form? This question has preoccupied the geosciences for more than a century. An international research team led by Dr. Stefan Peters from the Leibniz Institute for ...
Phys.org / The language of play: Hyenas use facial expressions and vocalizations to de-escalate
Scientists observed spotted hyenas (Crocuta crocuta) playing in the wild and found that their precise, sophisticated communication is on par with that of many primate species. Hyenas play and romp with one another at all ...
Phys.org / Unraveling a long-standing solar mystery: The extreme thinness of the sun's tachocline layer
Researchers are closer to unraveling a longstanding solar mystery surrounding the extreme thinness of the sun's tachocline layer of strong shearing motion—a region believed to be critical for creating the violent eruptions ...
