Phys.org / Finding runaway stars to help map dark matter in the Milky Way
Hypervelocity stars have, since the 1920s, been an important tool that allows astronomers to study the properties of the Milky Way galaxy, such as its gravitational potential and the distribution of matter. Now astronomers ...
Phys.org / Study unveils the dual nature of a young stellar object
Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have conducted a long-term photometric and spectroscopic study of a young stellar object known as V1180 Cassiopeiae. ...
Phys.org / Searching for light dark matter by tracking its direction with quantum sensors
Dark matter is an elusive type of matter that does not emit, absorb or reflect light, interacting very weakly with ordinary matter. These characteristics make it impossible to detect using conventional technologies used by ...
Phys.org / Tokamak experiments exceed plasma density limit, offering new approach to fusion ignition
Researchers working on China's fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have experimentally accessed a theorized "density-free regime" for fusion plasmas, achieving stable operation at densities ...
Phys.org / Recent discovery reveals Africa's oldest cremation pyre and complex ritual practices
About 9,500 years ago, a community of hunter-gatherers in central Africa cremated a small woman on an open pyre at the base of Mount Hora, a prominent natural landmark in northern Malawi, according to a new study coauthored ...
Phys.org / Genomic study reveals how people moved pigs across the Pacific
A new study, published in the journal Science, reveals how millennia of human migration across Pacific islands led to the introduction of invasive pig species all over the Asia-Pacific region.
Phys.org / A coral reef's daily pulse reshapes microbes in surrounding waters
Coral reefs are often described as biodiversity hotspots, but new research shows they also act as powerful regulators of the microscopic life in the surrounding ocean.
Phys.org / Experiment nixes 'sterile' neutrino explanation of previous unexpected measurements
Experimental particle physicists working at the MicroBooNE experiment at Fermilab National Accelerator Laboratory have found evidence against the existence of a "sterile" type of neutrino hypothesized to be responsible for ...
Phys.org / Physicists repair flaw of established quantum resource theorem
Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the past decades, researchers have introduced several new quantum information frameworks and theories ...
Phys.org / Sunlight-driven nanoparticles enable cleaner ammonia synthesis at room temperature
Ammonia (NH3) is a colorless chemical compound comprised of nitrogen and hydrogen that is widely used in agriculture and in industrial settings. Among other things, it is used to produce fertilizers, as well as cleaning products ...
Phys.org / Einstein Probe detects an X-ray flare from nearby star
Using the Einstein Probe (EP), astronomers have detected a new X-ray transient event, which turned out to be an X-ray flare from the star PM J23221-0301 located about 150 light years away. The finding was reported in a research ...
Phys.org / Climate policies can backfire by eroding 'green' values, study finds
A popular vision of life after climate action looks like vegetarians riding bikes, city centers without cars, and people foregoing air travel. But a new paper published in Nature Sustainability finds that climate policies ...
