What Is an Atomic Clock?

Clock is ticking: A technology demonstration that could transform the way humans explore space is nearing its target launch date of June 24, 2019. Developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, the Deep Space Atomic Clock is a serious upgrade to the satellite-based atomic clocks that, for example, enable the GPS on your phone.

Work on the Thirty Meter Telescope on Mauna Kea, bitterly opposed by Hawaiian activists, may soon be underway.

Computer vision researchers report using special light sources and sensors to see around corners or through gauzy filters, letting them reconstruct the shapes of unseen objects.

Researchers from CSIRO’s Data61, the data and digital specialist arm of Australia’s national science agency, have developed a world-first set of techniques to effectively ‘vaccinate’ algorithms against adversarial attacks, a significant advancement in machine learning research.

International team spearheaded by researchers at McGill University has discovered a biological mechanism that could explain heightened somatic awareness, a condition where patients experience physical discomforts for which there is no physiological explanation.
