Hollow Flashlight Ann Makosinski is a 16-year-old student who competed against thousands of other young inventors from around the world to win first prize and a $25,000 scholarship at Google's International Science Fair. She invented a battery-free flashlight. A free energy device that is powered by the heat in your hand. While visiting the Philippines, Ann found that many students couldn't study at home because they didn't have electricity for lighting. Unfortunately, this is a common problem for developing regions where people don't have access to power grids or can't afford the cost of electricity. Ann recalled reading how the human body had enough energy to power a 100-watt light bulb. This inspired her to think of how she could convert body heat directly into electricity to power a flashlight. She knew that heated conductive material causes electrons to spread outwards and that cold conductive material causes electrons to condense inwards. S...

Scientists Prove Einstein  Right the Most Elusive Particles in the Universe An artist's rendition of subatomic particle movement. Neutrino physicists examined neutrinos detected by the IceCube Observatory, and found that they adhere to Albert Einstein's theory of relativity. Once again, scientists have shown that Albert Einstein's theory of special relativity is right — this time, thanks to a particle detector buried deep beneath Antarctica. Scientists from the 1-gigaton IceCube Neutrino Observatory examined subatomic particles called  neutrinos : elusive, chargeless subatomic particles that are as small as electrons. The researchers wondered if these tiny, high-energy particles would deviate from the behavior predicted by the theory of special relativity. Specifically, they were testing Lorentz symmetry — the principle that the laws of physics are the same, whether you're an astronaut zooming through space at a million miles an ho...

Electronic Pills - Collecting Data Inside The Body After years of  investment  and development, wireless devices contained in swallowable capsules are now reaching the market. Israel-based Given Imaging and the researchers at the University of Buffalo in New York have developed ingestible capsules that record data from inside your body. These pills contain sensors or tiny cameras that collect information as they travel through the gastrointestinal tract before being excreted from the body a day or two later. These new electronic inventions transmit information such as acidity, pressure and temperature levels or images of the esophagus and intestine to your doctor's computer for analysis. Doctors often use invasive methods such as catheters, endoscopic instruments or radioisotopes for collecting information about the digestive tract. So device companies have been developing easier, less intrusive ways, to gather information. Digestive diseases and disorders ...
