Anti-noise silences wind turbines
If wind turbines clatter and whistle too loudly, they are only permitted to operate under partial load to protect the local residents - but this also means a lower electricity output. An active damping system cancels out the noise by producing counter-vibrations.
Hollywood hair is captured at last
UC San Diego computer scientists presented a new method for accurately capturing the shape and appearance of a person's hairstyle for use in animated films and video games.
MIT developing super-realistic image system
By producing "6-D" images, an MIT professor and colleagues are creating unusually realistic pictures that not only have a full three-dimensional appearance, but also respond to their environment, producing natural shadows and highlights depending on the direction and intensity of the illumination around them.
Key advance toward 'micro-spacecraft'
Fleets of inexpensive, pint-sized spacecraft are one giant leap closer to lift off. Researchers at the 236th National Meeting of the American Chemical Society describe a new, razor thin temperature-regulating film that brings this sci-fi vision of "micro-spacecraft" weighing barely 50 pounds and 10-pound "nano-spacecraft" closer to reality.
Fast quantum computer building block created
The fastest quantum computer bit that exploits the main advantage of the qubit over the conventional bit has been demonstrated by researchers at University of Michigan, U.S. Naval Research Laboratory and the University of California at San Diego.
Air-purifying church windows early nanotechnology
Stained glass windows that are painted with gold purify the air when they are lit up by sunlight, a team of Queensland University of Technology experts have discovered.
'Can you see me now?' sign language over cell phones comes to United States
A group at the University of Washington has developed software that for the first time enables deaf and hard-of-hearing Americans to use sign language over a mobile phone. UW engineers got the phones working together this spring, and recently received a National Science Foundation grant for a 20-person field project that will begin next year in Seattle.
The 160-mile download diet: local file-sharing drastically cuts network load
Ever since Bram Cohen invented BitTorrent, Web traffic has never been the same. Whether that's a good thing or a bad thing, however, is a matter of debate.
MIT model helps computers sort data more like humans
Humans have a natural tendency to find order in sets of information, a skill that has proven difficult to replicate in computers. Faced with a large set of data, computers don't know where to begin -- unless they're programmed to look for a specific structure, such as a hierarchy, linear order, or a set of clusters.
'Omnivorous engine' hopes to run on many fuels
The "omnivorous engine" is no picky eater. Gasoline? Down the hatch. Ethanol? Butanol? It'll slurp those up too. The creators of the omnivorous engine, engineers at the U.S. Department of Energy's Argonne National Laboratory, seek to fashion an engine that can run on just about any type of spark-ignited fuel.

Disruption-free videos
Standardized video coding techniques still have their snags - digitally transmitted images are not always disruption-free. An extension of the H.264/AVC coding format allows to protect the most important data packets to ensure they arrive safely at the receiver.
I can't believe it's not fried: new oven fries food without oil
A new type of oven quickly produces foods that appear and taste identical to those that were fried, but, unlike traditional fryers, uses no additional oil.
Robotic vacuum offers shipping industry a cleaner solution
An automated robotic cleaning system that removes marine growth from the hull of a ship is being pioneered at Newcastle University.
Scientists create world's thinnest balloon, just 1 atom thick
Using a lump of graphite, a piece of Scotch tape and a silicon wafer, Cornell researchers have created a balloonlike membrane that is just one atom thick -- but strong enough to contain gases under several atmospheres of pressure without popping.
Carbon dioxide 'scrubber' captures greenhouse gases
University of Calgary climate change scientist David Keith and his team are working to efficiently capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology.
New robotic repair system will fix ailing satellites
Researchers at Queen's University are developing a new robotic system to service more than 8,000 satellites now orbiting the Earth, beyond the flight range of ground-based repair operations. Currently, when the high-flying celestial objects malfunction - or simply run out of fuel - they become "space junk" cluttering the cosmos.
Engineers aim to solve 'burning' computer problem
Two researchers at the University of Virginia's School of Engineering and Applied Science aim to lay the scientific groundwork that will solve the problem using nanoelectronics, considered the essential science for powering the next generation of computers.
Scientists explore putting electric cars on a two-way power street
Think of it as the end of cars' slacker days: No more sitting idle for hours in parking lots or garages racking up payments, but instead earning their keep by providing power to the electricity grid.
Scientists design bomb-proof thermometer to measure the heat of explosions
Scientists at the UK's National Physical Laboratory (NPL) in Teddington have designed a high-speed thermometer that can measure the temperature inside explosions without being damaged in the impact.
Researchers design artificial cells that could power medical implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.

| Quotes | Ive always wanted to be a scientist. That way, I could get a bunch of grants and do research into whether money can really buy happiness.
Kyannke.
Ive always wanted to be somebody, but I see now I should have been more specific.
