Phys.org / Study identifies key mechanism regulating how cells use fat to generate energy
An international study by scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) and the University of California, Los Angeles (UCLA) has identified a fundamental mechanism that regulates ...
Phys.org / 'Check your ingredients': A new blueprint for using Fermi's 'Golden Rule'
Underpinning much of modern technology, from smartphones to scanning tunneling microscopes to particle colliders, is Fermi's Golden Rule. Named for 20th-century Italian American physicist Enrico Fermi (but actually discovered ...
Phys.org / Aging rewires RNA production, favoring short genes over long neuronal ones
A new Northwestern Medicine study published in the Proceedings of the National Academy of Sciences has explored the impacts of aging on essential cellular processes, findings that could shape the development of future anti-aging ...
Phys.org / Quantum optics may turn this rare visual phenomenon into an eye test
Modern life depends on quantum physics. It makes technologies such as GPS navigation, MRI scanners and computer chips possible. Now, the same science may also lead to a new way to test the health of our eyes. A University ...
Phys.org / Medieval Islamic societies considered lovesickness a distinct mental illness, research shows
Lovesickness was taken seriously as a distinct mental illness by physicians in the medieval Islamic world, new research shows. Islamic scholars considered lovesickness, which they called ʿishq, to be different from melancholy—unlike ...
Phys.org / Observing oscillations, flares and tornados on the sun
For six and a half days in July 2024, the balloon-borne solar observatory Sunrise III kept its gaze fixed on the sun. The stratospheric flight, which stretched from the northernmost tip of Sweden to Canada's Northwest Territories, ...
Phys.org / Heat waves push tropical forests past photosynthesis limits across 57 million hectares
As heat waves continue one after another, we are feeling their effects on our own bodies: It becomes harder for us to function normally. Trees also have their limits when temperatures are too high. Above a certain critical ...
Phys.org / Transparent nanosheets could shrink phone cameras while preserving high-resolution color images
Researchers at Nagoya University in Japan have developed gallium-doped zinc oxide (GZO) nanosheets that may enhance camera resolution in compact devices, including smartphones and medical endoscopes.
Phys.org / Newborn stars preserve organic-rich gas within ancient supernova debris
For the first time, astronomers have discovered stellar cocoons rich in complex organic molecules within a supernova remnant. A research team from Niigata University, Gifu University, RIKEN and Kyoto University in Japan used ...
Phys.org / The ghost in Orion's shell: Hydrogen maps show repeated stellar feedback sculpted around Orion Nebula
An international team led by Juan Diego Soler at the University of Vienna used two of the world's most powerful radio telescopes to uncover previously hidden structures within the Orion Nebula. The project produced the sharpest ...
Phys.org / Fish DNA and 10,000 crystals rewrite Colorado River's Grand Canyon origin story
For more than 150 years, scientists have debated when and how the Colorado River first carved its way through the Grand Canyon. Now, a new study led by researchers at the University of New Mexico offers evidence that the ...
Phys.org / Krill buildup could slow fin whale filter-feeding unless baleen stays 15% clear
Usually there's safety in numbers, but it doesn't always work that way. Fin whales (Balaenoptera physalus) filter-feed on immense shoals of krill, engulfing colossal mouthfuls of water containing up to 144 kg of the crustaceans. ...
