    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.

    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...

    Self-Learning Heat­ing Control system Saves Energy

    Can buildings learn to save all by themselves? Researchers think so. In their experiments, they fed a new self-learning heat­ing control system with temperature data from the previous year and the current weather forecast. The ‘smart’ control system was then able to assess the building’s behavior and act with good anticipation. The result: greater comfort, lower energy costs.

    Factory halls, airport terminals and high-rise office buildings are often equipped with automated “anticipatory” heating systems...

    Newest Solar Telescope produces First Images

    February 1, 2020, Categories  Astronomy/Space

    Cell-like structures on the surface of the sun
    The Daniel K. Inouye Solar Telescope has produced the highest resolution image of the sun’s surface ever taken. In this picture, taken at 789 nanometers (nm), we can see features as small as 30km (18 miles) in size for the first time ever. The image shows a pattern of turbulent, “boiling” gas that covers the entire sun. The cell-like structures — each about the size of Texas — are the signature of violent motions that transport heat from the inside of the sun to its surface. Hot solar material (plasma) rises in the bright centers of “cells,” cools off and then sinks below the surface in dark lanes in a process known as convection. In these dark lanes we can also see the tiny, bright markers of magnetic fields...
