Brain-to-brain communication over the Internet
By Darren Quick
22:14 October 6, 2009 PDT
Brain-Computer Interfacing (BCI) is a hot area of research. In the past year alone we’ve looked at a system to allow people to control a robotic arm and another that enables users to control an ASIMO robot with nothing but the power of thought. Such systems rely on the use of an electroencephalograph (EEG) to capture brain waves and translate them into commands to control a machine. Now researchers at the University of Southampton have used a similar technique to show it is possible to transmit thoughts from one person to another. Read More
Femtoseconds lasers will help formation flying in space
14:26 October 6, 2009 PDT
Theoretical work commissioned to the National Physical Laboratory (NPL) by the European Space Agency has recently concluded that lasers capable of generating extremely short pulses — known as "femtosecond comb lasers" — could be of great help in measuring the distance between two or more spacecraft to an accuracy of just a few microns, an essential component to formation flying space missions scheduled for the next decades.

A hard rain's gonna fall on exoplanet COROT-7b
By Mick Webb
04:12 October 5, 2009 PDT
Raining rocks? The concept may not be as preposterous as it sounds according to scientists at Washington University in St Louis who have theorized that a recently-discovered exoplanet, COROT-7b, may have an atmosphere that does exactly that. Read More
'Time telescope' speeds up optical transmission by 27 times
22:17 October 4, 2009 PDT
Most of today's telecommunication data is encoded at a speed of 10 Gbit/s, but researchers are constantly looking for new ways to push this limit even further. A group of researchers at Cornell University have recently come up with the "time telescope," a sophisticated system that can speed up optical communication by 27 times to an outstanding 270 Gbits/s by squeezing more information into a single flash of light and that, unlike previous solutions, does so in an energy-efficient manner.

Scientists block insects' sense of smell to protect crops
By Jeff Salton
15:00 September 27, 2009 PDT
Good news for crop farmers this week with UK scientists discovering molecules they hope will confuse insects’ sense of smell and therefore their ability to detect plants – and each other. The researchers believe this could reduce the damage insects cause to crops and lead to better food security. Roughly one-quarter of the world’s crops are lost annually to pests and disease.

Adding graphene could mean cheaper Lithium-ion batteries
By Darren Quick
01:01 September 23, 2009 PDT
It’s not only integrated circuits that look set to benefit from the use of graphene, the one-atom thick wonder material made up of a honeycomb lattice of carbon atoms. Researchers have discovered that adding graphene to titanium dioxide for use as electrodes in batteries improves performance over standard titanium oxide by a factor of three. This could pave the way for inexpensive titanium dioxide to replace the expensive, rare-earth metals or fire-prone carbon-based materials used in today's lithium-ion batteries. Read More

NAVTEQ study shows traffic-enabled navigation saves drivers four days a year
By Jude Garvey
01:47 September 16, 2009 PDT
It wasn’t so long ago that most of us relied on the humble road map to get us from A to B, but with the advent of GPS navigation systems, our map-reading skills are rarely required. There is no denying the usefulness of GPS systems, particularly if you have a tendency to get lost, but do they actually save you time? According to a recent proprietary research study, if you have a traffic-enabled GPS and spend most of your time on busy roads, you could save yourself up to four days a year. Read More
Heart of research lies in Xbox 360 chip
By Jeff Salton
21:27 September 15, 2009 PDT
Finally, video-gamers whose parents told them that playing games would never help them get a job can point to research that proves them wrong – well, sort of, anyway. A new study by a University of Warwick researcher has demonstrated that scientists trying to model a range of processes could ‘borrow’ an Xbox chip to get all the power and capabilities they need, saving thousands of dollars on parallel processing hardware and/or countless man-hours.

Carbon nanotubes used to build a near-ideal efficiency solar cell
04:34 September 14, 2009 PDT
Today's photovoltaic technology, while certainly promising, offers very poor efficiency because of inherent issues in its working mechanism. Using carbon nanotubes, however, Cornell University researchers now hope to lead the way to the next generation of highly efficient solar panels. Read More
Graffiti-proofing our history
By Jeff Salton
01:09 September 14, 2009 PDT
Graffiti is not only ugly, it costs society millions of dollars to remove it. But graffiti on historic landmarks is worse because it often can't be removed using basic caustic solutions without damage to the underlying surface. Now a new, breathable coating could help preserve some of our most beautiful and priceless links to the past by providing them with an efficient, all-round protection against attacks by taggers.

By Darren Quick
00:54 September 14, 2009 PDT
Conventional blast-resistant glass is more than an inch thick and expensive, but researchers are developing and testing a new type of blast-resistant glass that is less than one-half of an inch thick, lighter and yet less vulnerable to small-scale explosions. Read More

Arctic warming overtakes 2,000 years of natural cooling
By Gizmag Team
20:55 September 6, 2009 PDT
Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates. The study, which incorporates geologic records and computer simulations, provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns. The international study, led by Northern Arizona University and the National Center for Atmospheric Research (NCAR), will be published in the September 4 edition of Science. Read More

Nanoscale lasers continue to shrink, heralding new era in optical science
By Darren Quick
20:28 August 31, 2009 PDT
Breakthroughs are coming thick and fast – or should that be thin and fast – in the field of nanoscale lasers. It wasn’t even a month ago that we reported on the development of a laser emitting 'metal-semiconductor-metal sandwich', made up of a semiconductor as thin as 80 nanometers laying between 20-nanometer dielectric layers. But now researchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than a single protein molecule.

Organic molecule sandwich may satisfy appetite for molecule-sized electronic components
By Darren Quick
21:37 August 27, 2009 PDT
Researchers have found a way of sandwiching organic molecules between silicon and metal that could allow the creation of electronic switches made from individual molecules. Using molecules as switches carries the promise of even smaller electronic components that can be produced cheaply in huge numbers, perform faster than their larger silicon brethren, and use only a fraction of their energy.

Extending Moore’s Law using nuclear fusion
By Darren Quick
22:22 August 20, 2009 PDT
We recently looked at a technique that could help extend Moore’s Law by using DNA molecules as scaffolding to pack more power and speed into computer chips. Now researchers from Purdue University and the U.S. Department of Energy's Argonne National Laboratory are working to achieve the same result by adapting the same methods used in fusion-energy research to create extremely thin plasma beams for a new class of 'nanolithography'.
