Fundamental to the Internet of Things is the idea that objects must be uniquely identifiable. RFID chips are perfect for assigning objects a digital fingerprint, at least so far as traditional manufacturing goes. But with the rise of 3D printing, incorporating an RFID chip into your object means interrupting the printing process. Now, scientists have come up with a way to 3D print a unique tag, called an InfraStruct, inside the object as it's being printed, and it's made possible by the slowly emerging field of terahertz imaging.  Read More

Having produced the Coolpix S800c, Nikon has experience of working with Android on a camer...

It's no secret the compact camera market is taking a beating. Yes, people are taking more photos than ever, but not on dedicated point-and-shoots. Increasingly they're reaching for their smartphone when a photographic opportunity arises. Nikon President, Makoto Kimura, told Bloomberg his company is well aware of this trend and wants to create new products aimed at this bigger market, hinting at the possibility of a smartphone by saying the company is considering a "non-camera consumer product."  Read More

The Kinograph utilizes 3D-printed rollers to create an affordable system for digitizing 35...

As the Raspberry Pi Foundation (RPF) has worked to make computing more accessible, it has helped pioneer new ways of using technology. We've seen the versatile, board-based Raspberry Pi enabling everything from robotic bartenders to doggie treat dispensers. The latest project featuring the Pi comes from Matthew Epler, whose Pi-powered Kinogarph digitizes old film stock at a fraction of the cost of conventional off-the-shelf systems.  Read More

A new Wi-Fi-based 'Wi-Vi' system can track people moving behind walls (Image: Christine Da...

Researchers at MIT's Computer Science and Artificial Intelligence Laboratory have developed what could become low-cost, X-ray vision. The system, known as "Wi-Vi," is based on a concept similar to radar and sonar imaging, but rather than using high-power signals, this tech uses reflected Wi-Fi signals to track the movement of people behind walls and closed doors.  Read More

A team of scientists at Nanyang Technological University (NTU) in Singapore has developed a new image sensor from graphene that promises to improve the quality of images captured in low light conditions. In tests, NTU claims it has proved to be 1,000 times more sensitive to light than existing complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD) camera sensors in addition to operating at much lower voltages, consequently using 10 times less energy.  Read More

3D images taken in daylight from 910 meters away using the new imaging system (Photo: Opti...

Physicists at Scotland’s Heriot-Watt University have created a 3D imaging camera system capable of resolving depth on a millimeter scale at distances of up to one kilometer. Working much like a laser version of radar, the “Time-of-Flight” (ToF) measurement system “pings” a low-powered infrared laser beam off distant objects and records a pixel-by-pixel map using a detector that counts and positions individual photons as they arrive back at the source.  Read More

While the number of exoplanets so far identified is steadily marching towards the 1000 mark, fewer than twenty have been discovered in the course of direct observation by astronomical telescopes. Four of them (HR 8977 b,c,d,and e) circle an unprepossessing A5 star called HR 8977, which lies about 130 light-years distant from Earth. Thanks to the little-known astrophysics research arm of the American Museum of Natural History (AMNH), we now have the ability to examine the makeup of their atmospheres by taking simultaneous spectrographs of all four planets.  Read More

The newest Landsat satellite has transmitted its first images back home (Image: NASA)

We haven't heard anything from NASA's Landsat Data Continuity Mission (LDCM) spacecraft since its launch in February, but the satellite is now ready to start sending its first images back home. The first batch of photos are part of a three-month testing period, and show the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. Viewed from space, it's already a pretty spectacular scene, but the images from the LDCM managed to enhance it even further.  Read More

We report on the latest developments in biological research all the time here at Gizmag, but it's easy to forget just how beautiful biology can appear when observed at the cellular level. On this note, GE Healthcare’s Life Sciences Cell Imaging Competition has announced its winners for 2012, giving us the opportunity to appreciate the images which will soon light up New York’s Times Square.  Read More

Researchers have created a bendable, transparent polymer that acts as an image sensor (Pho...

A research team from the Johannes Kepler University Linz in Austria has developed an image capturing device using a single sheet of polymer that is flat, flexible and transparent. The researchers say the new image sensor could eventually find its way into devices like digital cameras and medical scanners, and that it may help to usher in a new generation of gesture-controlled smartphones, tablets and TVs.  Read More
