A team of researchers working at the University of Chicago has found a way to use sound waves to model a system for rotational dynamics of inertial many-particle clustering. In their paper published in the journal Physical ...
Astronomers at the University of Sydney have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss, possibly due to the presence a greedy neighbor. Published in Nature ...
