Phys.org / Hundreds of economists say 'we must act now' on AI's economic impact and job displacement risks
Hundreds of economists say in an open letter that institutions "must act now" to address how artificial intelligence could transform the economy and could put many people out of work.
Medical Xpress / Eating an avocado a day lowers heart disease risk factor for people with obesity
Eating an avocado every day may decrease heart disease risk in adults with obesity, according to a recent study led by researchers in the Penn State Department of Nutritional Sciences and published in the Journal of Clinical ...
Phys.org / Volcanoes and wildfires are adding water vapor to the stratosphere, raising climate concerns
Moderate volcanic eruptions and extreme wildfires since 2005 have led to an increase in the amount of water vapor in the stratosphere, a layer of Earth's atmosphere above the weather-filled troposphere. That's potentially ...
Phys.org / Why climate scientists need to talk more about the very worst‑case scenarios
London is underwater. The Houses of Parliament, Buckingham Palace, St Paul's Cathedral and the Bank of England are all submerged. Far away, the West Antarctic and Greenland ice sheets have collapsed, triggering accelerated ...
Phys.org / Synthetic rotation brings black hole energy theory into lab, amplifying waves
More than half a century ago, Sir Roger Penrose envisioned a scenario in which energy could be extracted from a black hole spinning at extreme speeds. He proposed that a particle entering its ergosphere—a region of space ...
Medical Xpress / How an adolescent's brain reacts to faces may predict their social future
It's been said that eyes are a window to the soul, but new research has found that an adolescent's brain response to a face might open a window to their social future. A new study at the University of California, Davis Center ...
Phys.org / Nanoplastics found in Antarctic soils for first time, suggesting long-range atmospheric transport
Microplastic contamination has been a much-discussed topic over the last several years, but contamination from even smaller plastic particles represents another pressing issue. Nanoplastics—defined as being under a micrometer ...
Phys.org / The oldest deliberately collected fossil ichthyosaur was discovered in Roman Britain around 1,800 years ago
Around 1,800 years ago, a fossilized spinal bone lay on the windswept beaches of Roman Britain until a curious passerby picked it up and carried it far away, only to drop it in a pit.
Medical Xpress / Inhibiting protein to treat myeloproliferative neoplasms shows preclinical promise
Inhibiting menin, a protein that supports leukemia growth and is already targeted to treat some forms of leukemia, also holds promise for treating myeloproliferative neoplasms. A new study from scientists at St. Jude Children's ...
Phys.org / Evidence of elusive high-energy chiral graviton excitations in quantum Hall systems
Electrons, negatively charged particles, sometimes coordinate their movements in ways that produce certain collective excitations referred to as quasiparticles. One case in which this occurs is the quantum Hall effect, a ...
Phys.org / Climate oscillations shape nature's coral refuges in a warming ocean
Why do some coral reefs weather marine heat waves better than others? A new study published in Scientific Reports shows that the answer may lie not only in local ocean conditions, but also in climate patterns that span entire ...
Phys.org / Scientists uncover molecular mechanism linking water-saving irrigation to cadmium accumulation in rice
Water-saving irrigation practices, including intermittent irrigation, are essential for sustainable rice cultivation amid growing freshwater shortages. However, periodic drainage creates aerobic soil conditions that drastically ...
