Sharp Corporation has achieved the world's highest solar cell conversion efficiency of 44.4%, using a concentrator triple-junction compound solar cell. These solar cells are used in a lens-based concentrator system that focuses sunlight on the cells to generate electricity.
We've seen the robot that walks like a lizard, now meet the one that walks like a cat. Scientists have developed a four-legged, speedster "cheetah cub robot" that is small, light and fast--and could save lives.
As we age, our bodies slowly degenerate and decay. Yet a Russian multimillionaire aims to halt that process--at least when it comes to our brains. Dmitry Itskov has announced a new project that aims to make our minds immortal by transplanting them into a machine.
Google Inc has launched a small network of balloons over the Southern Hemisphere in an experiment it hopes could bring reliable Internet access to the world's most remote regions, the company said late Friday.
Europe's latest passenger jet, the Airbus A350, made its maiden flight on Friday and its chief salesman, opening a new front in a battle with U.S. rival Boeing Co (BA.N), declared it so quiet that airport residents won't even notice it.
In findings that could help overcome a major technological hurdle in the road toward smaller and more powerful electronics, an international research team involving University of Michigan engineering researchers, has shown the unique ways in which heat dissipates at the tiniest scales.
Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period of time to realize global quantum networks based on optical fibers.
One nature reserve has told visitors to stop using birdsong phone apps to attract certain species since they may harmful to the creatures, disrupting their usual activities.
A new material has the potential to improve the sensitivity of photographic image sensors by a factor of five. In 2011, an EPFL team led by Andras Kis discovered the amazing semi-conducting properties of molybdenite (MoS2), and they have been exploring its potential in various technological applicat...
ESA’s Proba-V has become the first satellite to pick up aircraft tracking signals, allowing aircraft across the globe to be followed in flight from space.
When you squeeze something, it usually gets smaller. Now it seems that scientists have defied these laws of physics, creating a new material that expands when it's squeezed.
If reports are to be believed, the US National Security Agency (NSA) has had “direct access” to systems run by Google, Facebook, Yahoo and Apple. While all the companies named have used similar words to deny those claims, the alleged scale of the surveillance, its sophistication and the lack of ...
