• Ambient blue light resets tired workers' body clocks

    Tedious work during the “wrong” hours of the body’s biological clock — think truckers who drive through the night, or security officers monitoring CCTV screens during the graveyard shift — often leads to drowsiness; falling asleep behind the wheel or in front of a security monitoring screen can lead to catastrophes; researchers develop a way to “fool” the brain to think it is morning

  • UCSD researchers develop tiny explosive sensor

    Sensor works by monitoring the variability of electrical conductivity through thin films of metal phthalocyanines; “The detection capability of this tiny electronic sensor is comparable to current instruments, which are large, bulky and cost thousands of dollars each,” says William Trogler, UCSD professor of chemistry and biochemistry

  • FIRST robotics competition comes back to UC Davis

    Robotic competition among high-school students aims to promote and reward students’ engagement in innovation and engineering, and encourage youngsters to become curious and interested in science and mathematics

  • Scottish university to auction off AI software predicting future trends

    Scottish university tries a new approach: One of its researchers developed artificial intelligence software which predicts the future, and the school will auction it off at an IP auction in San Francisco next month

  • Six-inch, bat-like UAV to assist in urban combat

    U.S. Army awards $10 million to Wolverines researchers to develop a six inch, bat-like UAV to be used in urban combat; UAV would gather data from sights, sounds, and smells in urban combat zones

  • Growth of facial recognition biometrics, II

    Some twenty states already use facial recognition in their DMVs, and more states are planning to do so; the federal government incorporates facial recognition in some of its important initiatives; privacy advocates are concerned that the technology is becoming too pervasive

  • Researchers warn that Lake Mead is drying up

    Lake Mead is a key source of water for for millions of people in the southwestern United States; research shows that if current trends — usage, climate change — continue, the lake may dry up by 2021

  • Serious RFID vulnerability discovered

    A group of a Dutch university’s digital security researchers discovers a major security flaw in a popular RFID tag; discovery can have serious commercial and national security implications; as important as the discovery itself was how the researchers handled the situation

  • First example of a third degree transcendental L-function exhibited

    “A glimpse of new worlds” — this is how Columbia University’s Dorian Goldfeld described the L-function breakthrough; L-functions hold most of the secrets of number theory, and now we are a step closer to lifting this veil of mystery

  • ORECon raises $24 million

    Innovative U.K. wave energy company raises $24 million in VC investment

  • Goal of making maritime transportation greener may be difficult to achieve

    The goal of making maritime transportation greener would be difficult to achieve; not all refineries have the capacity to provide the right fuel in the right quantity and concentration, therefore not enough of the more environmentally friendly fuel is available at all ports of the world

  • Bill would double cap on H-1B visas

    The United States allows millions of little-educated, low-skill immigrants to come to the country, while allocating a tiny number of visas to high-skill scientists and engineers; this is going to change, but critics complain that bill still leaves major problems — chief among them: setting wage floor for H-1B employees — unaddressed

  • The national security ramifications of climate change become clearer

    EU report adds urgency to old warnings about the consequences of climate change; NATO to take up discussion next

  • Benefits and risks of close science-defense collaboration

    This week was National Science and Engineering week in the United Kingdom — and the London events and exhibit emphasized the contribution scientists and engineers make to the defense of the kingdom; a venerable engineering magazine says we should be just a bit cautious here lest we turn the battlefield of the future into a publicly funded industrial testing ground, where commercial pressure would overwhelm the sober considerations of defense decision makers

  • Age-old communication problem solved using quantum entanglement

    One of the major problems in communication is known as the Byzantine agreement: Messages between three different parties are subject to faulty information; researchers succeeded in overcoming the qutrit difficulties by setting up a system that creates four-qubit entangled states
