• A Transparent Display Without Limits

    Projecting an image is simple - if the surface you're projecting it on is white and flat and in a dark room. However, projecting an image onto a transparent surface is much more complicated and expensive. But a research team at MIT has developed a new and affordable transparent display system that may one day change the way we look at store windows and windshields.

    The secret to MIT’s breakthrough display is a coating of silver nanoparticles on top of a thin transparent surface. These nanoparticles can identify certain wavelengths and colors, while letting the rest of the information from the projector pass through.

    This technology would allow stores to project images and information onto their windows in real time. Subway trains could post minute-to-minute service changes and delays, and your car would be able to display information right on the windshield.

    As opposed to other transparent displays, which are embedded with expensive electronics, this new technology has to potential to

  • New Telescope Will Be World’s Largest

    The Hubble Space Telescope has produced some jaw-dropping images from space, such as the famous “Pillars of Creation” and the Horsehead nebula.

    But the Hubble will soon encounter some stiff telescoping competition from a ground-based telescope so large it has been dubbed “E-ELT,” aka the European Extremely Large Telescope.

    The telescope is being designed by the European Southern Observatory, which will begin construction on a desert mountain top in Chile as soon as Brazil’s parliament ratifies the ESO’s charter and becomes a member state.

    With a reflecting telescope that will measure more than 39 meters (127.95 feet) in diameter, the E-ELT will be the largest telescope ever made.

    According to Jochen Liske, an ESO astronomer, the E-ELT will probe for extra-solar planets with Earth-like masses and conduct direct imaging of larger planets. By analyzing light from distant galaxies, the E-ELT will help astronomers understand more about how stars are formed.

  • Fitbit For Your Skin

    If you’re like me, you realize you’ve been in the sun too long only after your skin turns a pinker shade of medium-rare steak.


    But what if there was an app that could give us a head’s up before the sun’s ultraviolet radiation can do its damage? (Dramatic pause for effect). Of course there is.

    A Paris-based company called Netatmo has made a bracelet that measures sun intensity in real time. It relays that data to an app on your smartphone, which alerts you when you’re approaching your day’s limit. The app also gives sun exposure tips, tailored for your skin type and habits, and notifies you when you should apply sunscreen or put on a hat.

    Fred Potter, Netatmo’s CEO, said he first thought about making the bracelet, which is called June (after the calendar month with the longest days), after speaking with a woman who complained to him about sun spots. That conversation inspired him to market a skin-protection product for women in warm climates.
