Broadband wireless from a desk lamp?

11 hours ago

The Optical Society of America has highlighted an upcoming presentation at an annual optics conference San Diego in which the researchers from Germany will describe a method for encoding a wireless broadband signal through the light generated by a common household lamp. Visible-frequency signals have a tremendous advantage in bandwidth, and modulation would be so fast no one would notice the flickering.

Once a seafarers' scourge, the gribble could be biofuel hero

Mar 9

Tiny marine isopods called gribbles were for centuries the bane of sailors, whose vessels were quickly devoured. Even today, piers and docks are rapidly gnawed away, and researchers have now been attracted to the enzymes in their gut, which can convert wood into sugars without the help of microbes.

Alternative energy crops in space

Mar 9

What if space held the key to producing alternative energy crops on Earth? That's what researchers are hoping to find in a new experiment on the International Space Station. The experiment, National Lab Pathfinder-Cells 3, is aimed at learning whether microgravity can help jatropha curcas plant cells grow faster to produce biofuel, or renewable fuel derived from biological matter.

Creating synthetic sea shells from chalk and polystyrene cups

Mar 9

Scientists have made synthetic ‘sea shells’ from a mixture of chalk and polystyrene cups—and produced a tough new material that could make our homes and offices more durable.

New energy source comes from the common pea

Mar 5

If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source—a source that may be on your dinner plate tonight.

Microrings could nix wires for communications in homes

Mar 4

Purdue Univ. researchers have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in the homes and offices of the future.

The killing power of clay: Advancing antibacterial alternatives

Mar 4

Researchers from the Arizona State Univ. have helped advance understanding about the antibacterial activity of clay minerals and their ability to kill what the best antibiotics on the market can't touch.  

Underwater silk adhesive might suture wounds

Mar 3

Like silkworm moths, butterflies, and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, Univ. of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery.

Popular nanoparticle causes toxicity in fish

Mar 2

A nanoparticle growing in popularity as a bactericidal agent has been shown to be toxic to fish, according to a Purdue Univ. study. Tested on fathead minnows—an organism often used to test the effects of toxicity on aquatic life—nanosilver suspended in solution proved toxic and even lethal to the minnows.

Physicist writes a better formula to predict baseball success

Mar 2

An Iowa State Univ. physicist, studies the mysteries of the neutrino, the elementary particle that usually passes right through ordinary matter such as baseballs and home-run sluggers.

Lunar tires, space MRSA, and resonating microfluidics

Mar 5

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.  

A clean energy America…is it coming or not?

Feb 24

Almost a year ago, the buzz during the downturn was that the economic stimulus will help boost jobs in a sort of national improvement program reminiscent of the 1930s. Our coal would be phased out. Our grids would get smart. Our cars would get hybridized.
