Phys.org / Distant super-massive black hole shows high velocity sign of overeating
A new University of Leicester study shows how the uncontrolled growth of a distant supermassive black hole (SMBH) is revealed by the ejection of excess matter as a high velocity wind.
Phys.org / Study finds planetary waves linked to wild summer weather have tripled since 1950
Climate change has tripled the frequency of atmospheric wave events linked to extreme summer weather in the last 75 years and that may explain why long-range computer forecasts keep underestimating the surge in killer heat ...
Phys.org / Rare earth metals that compete for uptake may blunt their own environmental impact on aquatic organisms
In an increasingly connected world, rare earth metals with odd names such as lanthanum, cerium and yttrium have become strategic assets. They are used in everything from mobile phones to wind turbines to electric vehicles. ...
Phys.org / AI perceived more negatively than climate science or science in general
ChatGPT was released to the public in late 2022, and the promise and perils of artificial intelligence (AI) have loomed large in the public consciousness ever since. Because perceptions of a new technology like AI can help ...
Phys.org / Molecular markers found to influence meat quality in Nelore cattle
Researchers at São Paulo State University (UNESP) in Brazil have identified a robust set of genetic markers associated with meat quality in the Nelore cattle breed (Bos taurus indicus) genome. The results pave the way for ...
Phys.org / Speed-snap science: Solving for molecular details in a flash
How do we know exactly what is happening at a molecular level during extremely fast processes, such as burning during combustion? In less than the blink of an eye, one chemical compound and then another are present in a flame ...
Phys.org / Genetically modified yeast can create valuable materials from urine
Researchers from the Lawrence Berkeley National Laboratory (Berkeley Lab), UC Irvine, and the University of Illinois Urbana-Champaign (UIUC), have used biology to convert human urine into a valuable product. The team genetically ...
Phys.org / Tree rings reveal increasing rainfall seasonality in the Amazon
Scientists have used clues locked into tree rings to reveal major changes in the Amazon's rainfall cycle over the last 40 years: wet seasons are getting wetter and dry seasons drier.
Phys.org / Pulsing ultraluminous X-ray sources are unlikely origins of periodically active fast radio bursts
In the vast cosmos, fast radio bursts (FRBs) remain one of the most mysterious astrophysical phenomena ever discovered. These intense, millisecond-duration radio pulses can release in the radio band alone as much energy as ...
Phys.org / New research maps optimal locations for climate-fighting reforestation
New research from the Future Ecosystems for Africa program at the University of the Witwatersrand in South Africa, has created the most accurate maps yet of where reforestation can effectively combat climate change.
Phys.org / From asteroid mining to space rustling—what do we do when an asteroid threatens Earth?
Asteroids colliding with Earth might seem farfetched, but the planetary threat is real. Just this year news broke of an asteroid with a 1%–2% chance of a fatal collision occurring in 2032. While more recent measurements ...
Phys.org / Physicists validate ratio method for studying halo nuclei
Theories must stand up to practical testing, and this is especially true in physics. Researchers from Johannes Gutenberg University Mainz (JGU), Texas A&M University, Brookhaven National Laboratory, the University of Surrey ...
