    Low-Energy Solar Particles from beyond Earth found near the Sun

    February 4, 2020, Categories  Astronomy/Space

    Courtesy of NASA/Johns Hopkins APL/Steve Gribben Using data from NASA’s Parker Solar Probe, an SwRI-led team identified low-energy particles, the smoking gun pointing to interactions between slow- and fast-moving regions of the solar wind accelerating high-energy particles from beyond the orbit of Earth. Using Integrated Science Investigation of the Sun (IS☉IS) instrument data, they measured low-energy particles in the near-Sun environment that had likely traveled back toward the Sun, slowing against the tide of the solar wind while still retaining surprising energies.

    Previous studies have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar.

    The recent emergence of Wuhan coronavirus (2019-nCoV) has put the world on high alert for transcontinental transmission, reminiscent of the outbreak of SARS – also a coronavirus – in 2002-2003.

    Decade-long structural studies by Fang Li of the University of Minnesota, et al. have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar...

    First All-Optical, Stealth Encryption Technology developed

    February 4, 2020, Categories  Physics, Technology/Electronics

    Concept Optical Encryption Technology
    “Basically, the innovative breakthrough is that if you can’t detect it, you can’t steal it.” — Prof. Dan Sadot, Director of the Optical Communications Research Laboratory

    Optical end-to-end solution includes encryption, transmission, decryption, and detection. BGN Technologies, the technology-transfer company of Ben-Gurion University of the Negev (BGU), Israel, is introducing the first all-optical “stealth” encryption technology that will be significantly more secure and private for highly sensitive cloud-computing and data center network transmission. The new all-optical encryption innovation will be introduced at the Cybertech Global Tel Aviv conference taking place January 28-30, 2020 in Tel Aviv, Israel.

    “Today, information is still encrypted using digital techniques...

    An international team of astrophysicists led by Australian Professor Matthew Bailes, from the ARC Centre of Excellence of Gravitational Wave Discovery (OzGrav), has shown exciting new evidence for ‘frame-dragging’—how the spinning of a celestial body twists space and time—after tracking the orbit of an exotic stellar pair for almost two decades. The data, which is further evidence for Einstein’s theory of General Relativity, is published today the journal Science.

    More than a century ago, Albert Einstein published his iconic theory of General Relativity—that the force of gravity arises from the curvature of space and time and that objects, su...
