A new media marketing world increasingly dominated by mobile technologies, "shopping bots," recommendation systems and peer-to-peer networks has spawned a radical new online marketplace, challenging the old behaviors of buyers and sellers, according to a new report in the Journal of Service Research.

By dipping plain cotton cloth in a high-tech broth full of silver nanowires and carbon nanotubes, Stanford researchers have developed a new high-speed, low-cost filter that could easily be implemented to purify water in the developing world.

The Norwegian University of Science and Technology (NTNU) and the University of Erlangen-Nürnberg together with the Max Planck Institute for the Science of Light in Erlangen have recently developed and tested a technique exploiting imperfections in quantum cryptography systems to implement an attack.

Blockbusters like Avatar, UP or Toy Story 3 will bring the 3-D into home living rooms, televisions and computers. There are already displays available and the new Blu-Ray players can already play 3-dimensional movies based on MVC.

A Stanford mechanical engineer is using the biology of a gecko's sticky foot to create a robot that climbs. In the same way the small reptile can scale a wall of slick glass, the Stickybot can climb smooth surfaces with feet modeled on the intricate design of gecko toes.

A new approach to building an "artificial nose" – using fluorescent compounds and DNA – could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.

Researchers have found a way to implement wireless monitoring technology – with uses ranging from climate control to health and safety applications – by tapping into a building's heating, ventilating and air-conditioning (HVAC) ducts.

Technologies for using laser energy to destroy threats at a distance have been in development for many years. Today, these technologies -- known as directed energy weapons -- are maturing to the point of becoming deployable.

University of Washington engineers are developing the first device able to transmit American Sign Language over U.S. cellular networks. The tool is just completing its initial field test by participants in a UW summer program for deaf and hard-of-hearing students.

English and math teachers who took professional development courses online improved their instructional practices and boosted their subject knowledge scores, producing modest performance gains for their students.
