A New Optical System to Miniaturize Laser Cooling of Atoms

It's cool to be small. Scientists at the National Institute of Standards and Technology (NIST) have miniaturized the optical components required to cool atoms down to a few thousandths of a degree above absolute zero, the first step in employing them on microchips to drive a new generation of super-accurate atomic clocks, enable navigation without GPS, and simulate quantum systems.

Study Proposes Possible Existence of Stupendously Large Black Holes

A new research work proposes the prospective occurrence of “stupendously large black holes” (SLABS), which are much larger than the supermassive black holes (SMBHs) already spotted at the centers of galaxies.

Search for Axions From Nearby Star Betelgeuse Comes Up Empty

The elusive axion particle is many times lighter than an electron, with properties that barely make an impression on ordinary matter. As such, the ghost-like particle is a leading contender as a component of dark matter — a hypothetical, invisible type of matter that is thought to make up 85 percent of the mass in the universe.
