New thin, flat lenses focus light as sharply as curved lenses

Lenses appear in all sorts of everyday objects, from prescription eyeglasses to cell-phone cameras. Typically, lenses rely on a curved shape to bend and focus light. But in the tight spaces inside consumer electronics and fiber-optic systems, these rounded lenses can take up a lot of room. Over the last few years, scientists have started crafting tiny flat lenses that are ideal for such close quarters. To date, however, thin microlenses have failed to transmit and focus light as efficiently as their bigger, curved counterparts.

GPM and Suomi-NPP fly above subtropical storm Ana

During the past few days subtropical storm ANA was developing off the southeastern coast of the United States. Yesterday and today the GPM core observatory satellite had two good views of subtropical storm ANA. The image above shows the developing subtropical storm on May 7, 2015 at 1636 UTC (12:36 PM EDT). This GPM pass occurred a little over 10 hours before the National Hurricane Center (NHC) issued their first advisory at 0300 UTC ( 11:00 PM EDT). This image shows rainfall derived from GPM's Ku/Ka-band Dual-frequency Precipitation Radar (DPR) and a multi-channel GPM Microwave Imager (GMI) instruments.

Amazon drone patent has tracking, talking details

How might those proposed delivery drones from Amazon operate? Details have been published by the US Patent Office. By pulling data from people's smartphones, the drones may track the location of the delivery target. The patent, titled "Unmanned Aerial Vehicle Delivery System," discussed a scenario where a user could choose a "Bring It To Me" option, where the user's location is determined and the UAV delivers the item. "The current location of the user may be based on, for example, a determined location of a portable device (e.g., mobile phone) associated with the user, the location of the network utilized by the user when placing the order, etc. For example, the user may identify their current location by allowing Global Positioning System ('GPS') data to be provided by their mobile device. Alternatively, if the user is connected through a wireless network (e.g., cellular, Wi-Fi, satellite), the location of the network may be det! ermined and used as the current location of the user."
