World Record: Wireless Data Transmission at 100 Gbit/S

World Record: Wireless Data Transmission at 100 Gbit/S

Extension of cable-based telecommunication networks requires high investments in both conurbations and rural areas. Broadband data transmission via radio relay links might help to cross rivers, motorways or nature protection areas at strategic node points, and to make network extension economically feasible. In the current issue of the nature photonics magazine, researchers present a method [...]

Innovation in Renewable-Energy Technologies Is Booming

Innovation in Renewable-Energy Technologies Is Booming

The number of patents issued for renewable-energy technologies has risen sharply over the last decade, according to new research from MIT and the Santa Fe Institute (SFI). The study shows that investments in research and development, as well as in the growth of markets for these products, have helped to spur this dramatic growth in [...]

Flawed Diamonds: Gems for New Technology

Flawed Diamonds: Gems for New Technology

A team of researchers led by University of Arizona assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds that contain nitrogen-vacancy centers — defects in which two adjacent carbon atoms in the diamond’s crystal structure are replaced by a single nitrogen atom and an empty gap.   These [...]

Neglected Statistical Tool Could Help Robots Better Understand the Objects in the World Around Them

Neglected Statistical Tool Could Help Robots Better Understand the Objects in the World Around Them

Object recognition is one of the most widely studied problems in computer vision. But a robot that manipulates objects in the world needs to do more than just recognize them; it also needs to understand their orientation. Is that mug right-side up or upside-down? And which direction is its handle facing?   To improve robots’ [...]

Printed Electronics: A Multi-Touch Sensor Customizable With Scissors

Printed Electronics: A Multi-Touch Sensor Customizable With Scissors

If a pair of long pants is too long, it is cut to length. A board that does not fit into a bookcase is sawed to the right length. People often customize the size and shape of materials like textiles and wood without turning to specialists like tailors or carpenters. In the future this should [...]

Video Game Technology: Motion Tracking Technology Is Extremely Precise, Inexpensive With Minimal Lag

Video Game Technology: Motion Tracking Technology Is Extremely Precise, Inexpensive With Minimal Lag

Researchers at Carnegie Mellon University and Disney Research Pittsburgh have devised a motion tracking technology that could eliminate much of the annoying lag that occurs in existing video game systems that use motion tracking, while also being extremely precise and highly affordable.   Called Lumitrack, the technology has two components — projectors and sensors. A [...]

Physicists ‘Entangle’ Microscopic Drum’s Beat With Electrical Signals

Physicists ‘Entangle’ Microscopic Drum’s Beat With Electrical Signals

Extending evidence of quantum behavior farther into the large-scale world of everyday life, physicists at the National Institute of Standards and Technology (NIST) have “entangled” — linked the properties of — a microscopic mechanical drum with electrical signals.   The results confirm that NIST’s micro-drum could be used as a quantum memory in future quantum [...]

Computer Scientists Develop New Approach to Sort Cells Up to 38 Times Faster

Computer Scientists Develop New Approach to Sort Cells Up to 38 Times Faster

A team of engineers led by computer scientists at the University of California, San Diego, has developed a new approach that marries computer vision and hardware optimization to sort cells up to 38 times faster than is currently possible. The approach could be used for clinical diagnostics, stem cell characterization and other applications.   The [...]

Measuring Height by Connecting Clocks

Measuring Height by Connecting Clocks

How far above sea level is a place located? And where exactly is “sea level”? It is one objective of the geodesists to answer these questions with 1 cm accuracy. Conventional measurement procedures or GPS technologies via satellites, however, reach their limits here. Now optical atomic clocks offer a new approach, because the tick rate [...]
