Egypt’s Antiquities Ministry says archaeologists are starting radar scans of the tomb of famed pharaoh Tutankhamun in the southern city of Luxor. The ministry said Thursday the scans will be carried out over a week to check for the existence of any hidden chambers behind the tomb. Egypt carried out previous scans as part of…
Underwater Wireless Optical Communications System For Streaming High Quality, Live Video
A flexible and cost-effective technology for streaming high-quality underwater video images has been developed by researchers at KAUST by improving the bandwidth to achieve better video quality. Oceans cover more than two-thirds of our planet and are a major source of biodiversity, food and medicines as well as containing vast reserves of oil, gas and…
Graphene Based Terahertz Absorbers
Graphene Flagship researches from CNR-Istituto Nanoscienze, Italy and the University of Cambridge, UK have shown that it is possible to create a terahertz saturable absorber using graphene produced by liquid phase exfoliation and deposited by transfer coating and ink jet printing. The paper, published in Nature Communications, reports a terahertz saturable absorber with an order of…
3-D LiDAR Sensor Enabling Detection Of Distances With Wide Angle Of View
Panasonic Corporation announced today that it has developed a 3-D LiDAR sensor that accurately measure the direction of and distance to objects with a wide angle of view, which is critical for autonomous operation of mobile robots. Employing Panasonic’s propriety laser-scanning technology, this 3-D LiDAR is capable of scanning the laser as wide as up…
Photo Of The Day: Drone Antenna Test
This 6 m-wingspan unmanned aircraft is supported in mid-air within ESA’s Hertz radio-frequency test chamber, as if suspended in flight, to check it can maintain contact with its controller through satellite links. The drone, developed by Barnard Microsystems Ltd of the UK, has been fitted with a steerable array antenna in its wing to keep contact with the Inmarsat…
The Sharpest Laser In The World: Physicists Develop A Laser With A Linewidth Of Only 10 mHz
No one had ever come so close to the ideal laser before: theoretically, laser light has only one single color (also frequency or wavelength). In reality, however, there is always a certain linewidth. With a linewidth of only 10 mHz, the laser that the researchers from the Physikalisch-Technische Bundesanstalt (PTB) have now developed together with…
Photo Of The Day: Mid-Infrared Images From The Subaru Telescope Extend Juno Spacecraft Discoveries
Subaru Telescope images reveal weather in Jupiter’s atmosphere in the mid-infrared. Those images, taken multiple times over several months, support Juno spacecraft mission of National Aeronautics and Space Administration (NASA). This article is part of a joint press release with ones from Jet Propulsion Laboratory (JPL) at California Institute of Technology and Gemini Observatory. High-resolution…
The Brighter Side Of Twisted Polymers
A strategy to produce highly fluorescent nanoparticles through careful molecular design of conjugated polymers has been developed by KAUST researchers. Such tiny polymer-based particles could offer alternatives to conventional organic dyes and inorganic semiconductor quantum dots as fluorescent tags for medical imaging. Conjugated polymer-derived nanoparticles, called Pdots, are expected to transform several areas, including optoelectronics,…
Physicists Demonstrate Photonic Hypercrystals For Control Of Light-Matter Interaction
Control of light-matter interaction is central to fundamental phenomena and technologies such as photosynthesis, lasers, LEDs and solar cells. City College of New York researchers have now demonstrated a new class of artificial media called photonic hypercrystals that can control light-matter interaction in unprecedented ways. This could lead to such benefits as ultrafast LEDs for…
Scientists Develop Device To Predict Clear-Sky Turbulence For Safer Air Travel
Turbulence in clear skies comprises the most unpleasant kind of vortex drifts in air travel. These occur in cloudless space with perfect visibility when an airplane travels between air flows that differ in direction, speed of movement, temperature and density. This is the kind of turbulence that Aeroflot flight SU-270 from Moscow to Bangkok experienced,…
