The Hindu : Health : Breakthrough: sensors that can convert thoughts into speech. 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.

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. A rough estimate of calories per day can be obtained by multiplying the ideal weight for your height and body type by a number based on your level of physical activity, ranging from 11 for a pure couch potato to 17 for a person engaged in heavy physical labour or strenuous exercise on a daily basis. The following tables give estimates of the calories burned per day for men and women at their ideal weight, based on height and body type. Height in these tables is your barefoot height. Daily calories burned: Men Daily calories burned: Women. Cell Size and Scale.
Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long.
That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Smaller cells are easily visible under a light microscope. BioMotionLab. A Sense of Scale: Absolute Zero. 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.

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.

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. He didn’t get the job. Teenagers' brains 'can resist temptation'
