Phys.org / A famous galaxy's black hole has been hiding its most violent behavior
Astronomers have found that a nearby galaxy's black hole is blasting out a far more powerful and hidden gas outflow than previously realized. Studying NGC 1068, a well-known galaxy with an actively feeding black hole at its ...
Phys.org / New species of 240-million-year-old prehistoric animal could reshape dinosaur origins timeline
A new prehistoric animal species from Tanzania dating to around 240 million years ago, during the Triassic period, has been described by an international team of researchers. Led by the University of Bristol, the new species, ...
Phys.org / History is being rewritten at an archaeological site in Morocco. What the discovery of an ancient wall tells us
In the hills of northwestern Morocco, overlooking the river that gives the site its name, research at Oued Beht is bringing to light a previously unknown chapter of the region's past. The discovery of a substantial built ...
Phys.org / For many group-living females, breeding and raising young are shared endeavors
Some female animals living in groups raise offspring that are not their own, sometimes without reproducing themselves. While the behavior of cooperatively breeding species is well documented, some aspects remain poorly understood.
Phys.org / Ancient DNA traces medieval migration from Sweden to Finland
A new study led by the University of Turku provides new insights into the population history of Finland during the Late Iron Age and the Middle Ages. The researchers analyzed the genomes of people who lived in southwestern ...
Phys.org / Plasma and electricity convert CO₂ into methanol, butane and other useful chemicals
Carbon dioxide (CO₂) can be harmful to the environment in large amounts but can be used in the production of fuels and other useful chemicals. Doing so isn't easy, though. Now, Yale researchers have developed a new way to ...
Phys.org / Webb reveals dynamic panorama of star formation, including smallest known brown dwarfs
This starry view of the nearby star-forming region IC 348 is one of the largest images released to date from NASA's James Webb Space Telescope. Using Webb, astronomers searched IC 348 for brown dwarfs, which are less massive ...
Phys.org / Not all roads lead to Rome: Research challenges what we think we know about Roman roads
A multidisciplinary team of researchers from Aarhus University in Denmark, Queen Mary University of London and other European institutions analyzed a data set representing almost 300,000 kilometers (186,000 miles) of Roman ...
Phys.org / Heat-stable enzyme from deep-sea microbe turns nitrogen gas into ammonia
Microorganisms can do remarkable things—for example, nitrogen fixation, the conversion of nitrogen gas (N₂) into a form that organisms can use. Although nitrogen gas makes up around 78% of Earth's atmosphere, plants and animals ...
Phys.org / Greenhouse gas benefits of agricultural irrigation far outweigh emissions costs, study finds
Irrigating U.S. crops prevents higher greenhouse gas emissions by avoiding land conversion, new research by Colorado State University shows. Agricultural irrigation allows the United States to grow more food on less land. ...
Phys.org / Weather forecasts are significantly less accurate in poorer countries, analysis finds
Weather forecasts inform countless everyday decisions—from farmers deciding when to sow crops and energy companies anticipating demand to public authorities preparing for heat waves. But how useful those forecasts are depends ...
Phys.org / Responsibilities in close social relationships explain Eastern–Western cultural differences
Do you think that a person who reorganizes their life so that their aging parents can live with them would be likely to push another out of the way on the subway? What about greeting strangers with a smile? The answers to ...
