Planet says "cheese" for NASA's Earth Day "Global Selfie"

NASA has created a "Global Selfie" photomosaic comprised of over 36,000 individual photographs taken on or around April 22, 2014, also known as Earth Day. After several weeks spent sorting through the more than 50,000 images submitted – some of them were presumably not suitable for a family audience – the end result is a 3.2-gigapixel image that users can scan and zoom to view the individual photos.

Facial recognition is in (the reflection of) the eye of the beholder

The worst has happened. You receive an emailed kidnap demand with a picture of your loved one in dire straits. You contact the authorities, and in a flash (relatively speaking), they have identified the kidnapper and possibly some accomplices, and are well on their way toward recovering the victim. How did this happen? By identifying the faces of the kidnappers caught in the reflection of your loved one's eyes. Read More

Taking a peek at the Royal Navy's next nuclear-powered ballistic missile sub

As part of an update to Parliament on the progress of the Trident replacement program, Britain’s Ministry of Defence (MoD) has released a concept image of the Royal Navy’s next ballistic nuclear missile submarine. This coincides with the awarding of two contracts to BAE Systems Maritime-Submarines for £47 million (US$76 million) and £32 million (US$60 million) to begin preliminary design work on the nuclear-powered submarines, currently called the Successor class, which are intended to replace the Navy’s aging fleet of of Vanguard-class boats by 2028.

Shapify uses a Kinect to let users create a 3D Mini-Me from home

To make a three-dimensional color statue of yourself, you could grab a chunk of marble and enlist the services of a sculptor and a painter, or you could take the simple approach and use a 3D scanner and a 3D full-spectrum multicolor printer. Since the first option is expensive and time-consuming and very few of us have access to the equipment for the second, Shapify has launched a service that lets users scan themselves at home, using a Kinect.

“Mini Lisa” demonstrates potential of nanomanufacturing technique

Arguably the world’s most famous painting, da Vinci's Mona Lisa has now been copied onto the world’s smallest canvas at the Georgia Institute of Technology. Associate Professor Jennifer Curtis' "Mini Lisa" is one-third the width of a human hair, with details as small as one-eighth of a micron. Mini Lisa demonstrates the flexibility of a new nanolithography technique that can vary the surface concentration of molecules on very small portions of a substrate. Read More

Researchers produce ink and dye-free 100,000 DPI images

Researchers at Singapore's Institute of Materials Research and Engineering (IMRE), an institute of the Agency for Science, Technology and Research (A*STAR), have developed an innovative method of creating sharp, full-spectrum color images at 100,000 dots per inch (DPI). The method achieves this without need of ink or dye and bests the current crop of industrial inkjet and laserjet printers which are only able to offer up to 10,000 DPI. The new research also promises to outperform research-grade methods, which are able to dispense dyes for only single color images. Read More

Microwave map of entire moon revealed

The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang’E-1 is China’s first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution. Read More
