    What would you say to a cell phone that works without a battery? A barest-bone keypad and LD light as quite unsnazzy components? If you cannot live without showy capabilities of smartphones then you might have a good laugh—or consider this a step in a direction of further research you don’t want to miss. Researchers from the University of Washington showed one can work a phone without batteries in their device minus any bells or whistles. Their feat: “the team was able to successfully demonstrate a voice call from a battery-less phone to an Android smartphone,” said IFLScience.

    Their success was explained by Mark Harris, writing in Wired. “‘HELLO, HELLO. I am calling from a battery-free phone...

    Mid-infrared images from the Subaru telescope extend Juno spacecraft discoveries

    Image of Jupiter taken on May 18, 2017, one day before the Juno spacecraft’s sixth close approach to Jupiter, taken with a filter centered at 8.8 microns that is sensitive to Jupiter’s tropospheric temperatures and the thickness of a cloud near the condensation level of ammonia gas. The Great Red Spot appears distinctively at the lower center of the planet as a cold region with a thick cloud layer. It is surrounded by a warm and relatively clear periphery. To its northwest is a turbulent and chaotic region of gas with bands of alternative warm, dry and cold, moist gas. Many other features are also present...

    Hubble eyes a powerful Galaxy with a Password Name

    July 1, 2017, Categories  Astronomy/Space

    2XMM J143450.5+033843 lies nearly 400 million light-years away from Earth. It is a Seyfert galaxy that is dominated by something known as an Active Galactic Nucleus -- its core is thought to contain a supermassive black hole that is emitting huge amounts of radiation, pouring energetic X-rays out into the universe. The other fuzzy object in the frame was named in the same way -- it is a bright galaxy named 2XMM J143448.3+033749. Credit: ESA/Hubble & NASA

    Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by Hubble is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843...

    Miniature Technology, big Hope for Disease Detection

    June 30, 2017, Categories  Health/Medical, Biology/Biotechnology

    Image: First, a flexible stamp is inked with the APTES solution (i). The stamp is then pressed onto the glass surface (ii). A microfluidic channel is placed over the APTES pattern on the glass (iii), and the device is ready to be used to immobilize bioreceptors and, eventually, to help make a diagnosis (iv).
