The Hindu : Health : Breakthrough: sensors that can convert thoughts into speech - The Hindu: Mobile Edition The Hindu : Health : Breakthrough: sensors that can convert thoughts into speech - The Hindu: Mobile Edition A mind reading machine has edged closer to reality after scientists found a way of converting thoughts into words. Researchers were able to render brain signals into speech for the first time, relying on sensors attached to the brain surface. The breakthrough, which is up to 90 percent accurate, will be a boon for paralysed patients who cannot speak and could help read anyone’s thoughts ultimately, reports the Telegraph. “We were beside ourselves with excitement when it started working,” said Prof Bradley Greger, bioengineer at the Utah University who led the project. “It was just one of the moments when everything came together. “We have been able to decode spoken words using only signals from the brain with a device that has promise for long-term use in paralysed patients who cannot speak.

Steel's Melting Point is Approx. 1,370 °C (2,500 °F) Melting steel in a solar oven (aka solar concentrator) isn't new or unique, but it's always cool to see and a good reminder of just how much energy is hitting the sunny side of the planet at any moment. The video below shows a short exerpt of James May's "Big Ideas" series (James is better known for the Top Gear show), and they start by cooking, er, burning a sausage, and then they melt a steel plate. Impressive to see how quickly it turns to a liquid. Melting Steel With Only the Sun (Video) Melting Steel With Only the Sun (Video)

What you burn Next: What comes outUp: The Rubber Bag Previous: What goes in ``What you burn'' is the number of calories your body uses to provide the energy for everything you do, from heartbeats and breathing to running a marathon. The daily calorie requirement varies quite a bit from person to person depending on size, shape, basic metabolic rate, and degree of physical activity. What you burn

By Glenn Elert Posted 01.08.08 NOVA At roughly minus 460°F, absolute zero is abysmally cold, yet at least we can imagine it. Being only a few hundred degrees below zero, it's in the realm of something we can put our minds around. This is not true of the opposite of absolute zero, the theoretical highest possible temperature. In conventional physics, this is approximately 100 million million million million million degrees. In this interactive, get a taste of temperatures from absolute zero to absolute hot, and see why, for instance, even the core of the sun is relatively "chilly" compared to what many physicists believe the temperature of the universe was an instant after the Big Bang.

Map of the World Drawn Entirely Using Facebook Connections The above map of the world, drawn by Facebook data structuring intern Paul Butler using connections between 10 million Facebook friends (full-size link), is interesting enough in itself until you realize that all of the country borders are entirely drawn using Facebook friend connections too. Even if the world was dark and totally unmapped, Facebook could produce a remarkably good approximation of most of its continents’ boundaries, and even the borders of some countries. It still took some clever math. Butler explains how he did it: Map of the World Drawn Entirely Using Facebook Connections
Aerogel: See-Through, Strong as Steel & Ligher than Air Aerogel: See-Through, Strong as Steel & Ligher than Air Despite its incredibly low density, aerogel is one of the most powerful materials on the planet. It can support thousands of times its own weight, block out intense heat, cold and sound – yet it is 1,000 times less dense than glass, nearly as transparent and is composed of %99.8 air. The lowest-density silica-based aerogels are even lighter than air. Despite its fragility in certain regards and its incredible lack of density, aerogel has amazing thermal, acoustical and electrical insulation properties as illustrated by the images here. A single one-pound block can also support half a ton of weight. NASA continues to find new space-based applications for this incredible material.

First 3D Map of the Brain’s Connections First 3D Map of the Brain’s Connections We knew anatomy could be gorgeous, but this is beyond anything else we’ve ever seen, and it’s guaranteed to be something you haven’t seen, being the first 3D image of a brain’s connections. Van Wedeen, a Harvard radiology professor, is awestruck: “We’ve never really seen the brain – it’s been hiding in plain sight.” Conventional scanning has offered us a crude glimpse, but scientists such as Wedeen aim to produce the first ever three-dimensional map of all its neurons.

Chunnel Vision In the 1860’s, the British and French first began thinking about building a 30-plus mile tunnel under the English Channel to connect their two countries. The engineering companies estimated that it would cost over $10 million (U.S.) to complete– not a small piece of change 150 years ago. A little old Jewish man heard about their plans. He approached the Commissioner of Transportation and said he would do the job for $50,000. “How’s that possible?” he asked.
