"evidence for modified gravity at low acceleration from Gaia observations of wide binary stars." A potential replacement for dark matter scaling? Any physicists want to try to answer some questions? (phys.org)
My understanding is the researcher took Gaia probe information and looked at “wide binary stars” (not sure what defines wide, but there must be a ton of them), within 650 light years of earth. They found the ones that accelerate the least (relative to each other? Rotationally?) are, and this is where I get confused, moving...
One of 2023's most extreme heat waves is happening in the middle of winter (phys.org)
Temperatures in parts of Chile and northern Argentina have soared to 10°C–20°C above average over the last few days. Towns in the Andes mountains have reached 38°C or more, while Argentina's capital, Buenos Aires, saw temperatures above 30°C—breaking its previous August record by more than 5°C. Temperatures peaked at...
'Stunning' discovery: Metals can heal themselves (phys.org)
‘Stunning’ discovery: Metals can heal themselves::Scientists for the first time have witnessed pieces of metal crack, then fuse back together without any human intervention, overturning fundamental scientific theories in the process. If the newly discovered phenomenon can be harnessed, it could usher in an engineering...

Research group unveils properties of cosmic-ray sulfur and the composition of other primary cosmic rays (phys.org)
Charged cosmic rays, high-energy clusters of particles moving through space, were first described in 1912 by physicist Victor Hess. Since their discovery, they have been the topic of numerous astrophysics studies aimed at better understanding their origin, acceleration and propagation through space, using satellite data or other...
