Black holes, regions in spacetime where gravity is so strong that nothing can escape from them, are among the most fascinating and widely studied cosmic phenomena. While there are now countless theories about their formation ...
(Phys.org)—Illustrating the unusual way things work on the nanoscale, scientists have designed a new nanoelectromechanical system (NEMS) that produces mechanical motion due to the interactions between electrons—yet unlike ...
(Phys.org)—From petroleum refining to food processing, the vast majority of commercial chemical applications involve catalysts to control the rate of chemical reactions. Anything that can increase the efficiency of catalysts ...
(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...
(PhysOrg.com) -- As computer chips become more powerful, they also become hotter. Nearly all the power that flows into a chip comes out of it as waste heat, and that heat hurts the performance of the chip.
Astronomers report the discovery of a new warm Jupiter exoplanet orbiting a distant star in the open cluster Messier 67. The newfound extrasolar world, designated S1429 b, is almost twice as massive as Jupiter. The finding ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit ...
A team of astronomers and astrophysicists affiliated with several institutions in China, working with one colleague from Centro Ricerche Enrico Fermi, in Italy, and another from the University of Utah, in the U.S., has found ...
Nanofitins, which are derived from a protein found in Sulfolobus acidocaldarius—an archaeal microorganism found in hot springs—successfully neutralized SARS-CoV-2 in mice and were well-tolerated. When inhaled by the rodents, ...
