More Memory in a Smaller Space
September 22nd, 2009 · No Comments · Physics
We all store data. Whether it’s on our computers, dvrs or TiVo, iPods or cell-phones, we all care about data-storage. Physicists have discovered that size doesn’t necessarily matter in data storage. Most people would thing the bigger the hard disk, the bigger the flash drive, the more memory space it has. That is not always true, as we are [...]

Carbon Nanotubes Could Make Efficient Solar Cells
September 15th, 2009 · No Comments · Chemistry, Physics
Scientists have found that using a carbon nanotube instead of traditional silicon, can create the basic elements of a solar cell that should lead to much more efficient ways of converting light to electricity than now used in calculators and on rooftops. The device converts light to electricity that multiplies the amount of electrical current [...]

Lasers Generate Underwater Sound: Potential For Naval And Commercial Underwater Acoustic Applications
September 14th, 2009 · 1 Comment · Physics
A new technology for underwater acoustics is being developed by scientists at the Naval Research Laboratory. This technology uses flashes of lights and lasers to create sounds under the water. The conversion of light into sound can be achieved by sufficiently concentrating the light to “ionize” a very small amount of the water. The water [...]

Mice Levitated for Space Research
September 11th, 2009 · No Comments · Physics
“The scientists built a variable gravity simulator consisting of a superconducting magnet that could generate a magnetic field strong enough to levitate the water inside every cell in the mouse’s body.” They have tried this before with grasshoppers and frogs. But this is the first time it has been done with a mammal. The mice [...]
