Indian astronomers have conducted a study aimed at investigating a large-scale turbulence in the interstellar medium of a spiral galaxy known as NGC 6946. Results of the study, published October 4 on the pre-print server ...
Tailings, the waste left after extracting precious and critical minerals, often contain harmful chemicals and heavy metals that can pollute soil, water, and even crops. There are over 1,800 tailings storage facilities around ...

Non-perturbative interactions (i.e., interactions too strong to be described by so-called perturbation theory) between light and matter have been the topic of numerous research studies. Yet the role that quantum properties ...
Structured light waves with spiral phase fronts carry orbital angular momentum (OAM), attributed to the rotational motion of photons. Recently, scientists have been using light waves with OAM, and these special "helical" ...
