Researchers use web images to add realism to edited photos
Computer graphics researchers at Carnegie Mellon University have developed systems for editing or altering photographs using segments of the millions of images available on the Web.
Architects design building with 'digital water' walls
Imagine a building made of water. It features liquid curtains for walls - curtains that not only can be programmed to display images or messages but can also sense an approaching object and automatically part to let it through.
Scientists study how to make humanoid robots more graceful
Infants learn how to move by recognizing which movements and positions cause them physical discomfort and learning to avoid them. Computer science Professor Oussama Khatib and his research group at the Stanford Artificial Intelligence Laboratory are using the same principle to endow robots with the ability to perform multiple tasks simultaneously and smoothly.
Researchers develop inexpensive, easy process to produce solar panels
Researchers at New Jersey Institute of Technology (NJIT) have developed an inexpensive solar cell that can be painted or printed on flexible plastic sheets.
Higher efficiency organic solar cell
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at the Center for Polymers and Organic Solids at the University of California, Santa Barbara.
Mit team designs sleek, skintight spacesuit
In the 40 years that humans have been traveling into space, the suits they wear have changed very little. The bulky, gas-pressurized outfits give astronauts a bubble of protection, but their significant mass and the pressure itself severely limit mobility.
Wobbly polarity is key to preventing magnetic avalanches on disk drives
Push two magnets together and you'll set off an avalanche of activity, forcing atoms on each magnet to align their polarity with the intruding magnetic field. It may sound like a party trick for physicists, but you do it every time you press "Save" on your computer.
Diy anti-satellite systemPrivacy protection software utilities
Satellite tracking software freely available on the Internet and some textbook physics could be used by any organization that can get hold of an intermediate range rocket to mount an unsophisticated attack on military or civilian satellites. Such an attack would require modest engineering capability and only a limited budget. That is according to researchers writing in Inderscience Publishers' International Journal of Critical Infrastructures.Did you know that all your internet history can be reviewed by anyone with access to simple free tool available online. The internet brings with it many advantages and disadvantages.
Tightly packed molecules lend unexpected strength to nanothin sheet of material
Scientists at the University of Chicago and Argonne National Laboratory have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness.
Va ushers in new era for prostheses for amputees
The first powered ankle-foot prosthesis, an important advance for lower limb amputees, was unveiled today at the Providence Veterans Affairs Medical Center.

Computer scientist plans bach over broadband
A singing computer scientist wants to use cutting-edge technology to create Europe's first successful Internet choir.
Scientists discover new way to study nanostructures
Scientists at the Georgia Institute of Technology have discovered a phenomenon which allows measurement of the mechanical motion of nanostructures by using the AC Josephson effect.
Research boosts wireless data transfer
New research at the Georgia Institute of Technology could soon make that tangle of wires under desks and in data centers a thing of the past.
Laser sets records in power and energy efficiency
The rise in global terrorism in recent years has brought significant attention to the needs for more advanced sensors and defense technologies to protect civilians and soldiers.
Nano propellers pump with proper chemistry
The ability to pump liquids at the cellular scale opens up exciting possibilities, such as precisely targeting medicines and regulating flow into and out of cells. But designing this molecular machinery has proven difficult.
Mit duo see people-powered crowd farm
Two graduate students at MIT's School of Architecture and Planning want to harvest the energy of human movement in urban settings, like commuters in a train station or fans at a concert.
Researchers produce firsts with bursts of light
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have generated extremely short pulses of light that are the strongest of their type ever produced and could prove invaluable in probing the ultra-fast motion of atoms and electrons. The scientists also made the first observations of a phenomenon called cross-phase modulation with this high-intensity light - a characteristic that could be used in numerous new light source technologies.
Graphene oxide paper could spawn a new class of materials
Nearly 2,000 years ago, the discovery of paper revolutionized human communication. Now researchers at Northwestern University have fabricated a new type of paper that they hope will create a revolution of its own -- and while it won't replace your notepad, this remarkably stiff and strong yet lightweight material should find use in a wide variety of applications.
Graphene nanoelectronics: making tomorrows computers from a pencil trace
A key discovery at Rensselaer Polytechnic Institute could help advance the role of graphene as a possible heir to copper and silicon in nanoelectronics.
Purdue 'milestone' a step toward advanced sensors, communications
Engineers at Purdue University have shown how to finely control the spectral properties of ultrafast light pulses, a step toward creating advanced sensors, more powerful communications technologies and more precise laboratory instruments.
