Physicists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, have produced a gas of potassium-rubidium molecules at temperatures as low as 50 nanokelvin (nK) — that’s 50 billionths of a Kelvin, or just a smidge above absolute zero. The two atoms involved are in different [...] Read more

The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple [...] Read more

The new technique is the first of its kind that’s safe to use around humans. |SOURCE| Lasers can send sounds straight to a listener’s ear, like whispering a secret from afar. Using a laser tuned to interact with water vapor in the air, scientists created sounds in a localized spot that were loud enough to be picked up by human hearing if aimed [...] Read more

The long-awaited studies are based on the analysis of bones, artefacts and sediments from Denisova Cave in [...] Read more
