MIT helps develop new image-recognition softwareIt takes surprisingly few pixels of information to be able to identify the subject of an image, a team led by an MIT researcher has found. The discovery could lead to great advances in the automated identification of online images and, ultimately, provide a basis for computers to see like humans do.
Sunshade world - A global warming solution?Placing a 'sunshade' in space in order to counteract global warming was first proposed in 1989. More recent studies concluded that such a scheme could be developed and deployed in about 25 years time at a cost of several trillion dollars.
Studying the mechanics of microneedles
Steven Henry is seeking a better understanding of the force required to make microneedles penetrate the skin.
Magnet-controlled camera in the bodyImages from inside the body? It can be done with tiny cameras which the patient has to swallow. In the past there was no way of controlling the device as it passed through the body. Now it can be steered and stopped where desired, and even deliver images of the esophagus.
Electricity from the exhaust pipe
Researchers are working on a thermoelectric generator that converts the heat from car exhaust fumes into electricity. The module feeds the energy into the car's electronic systems. This cuts fuel consumption and helps reduce the CO2 emissions from motor vehicles.
New way to protect computer networks from Internet wormsScientists may have found a new way to combat the most dangerous form of computer virus. The method automatically detects within minutes when an Internet worm has infected a computer network. Network administrators can then isolate infected machines and hold them in quarantine for repairs.
Microrobotic ballet
Microscopic robots crafted to maneuver separately without any obvious guidance are now assembling into self-organized structures after years of continuing research led by a Duke University computer scientist.
Small suds make a big splash at seasThe latest engineering feat to emerge from the laboratories at Harvard's School of Engineering and Applied Sciences has been largely accomplished with the aid of kitchen mixers.
Quake research to provide rare glimpse of how structures collapse
Structural engineers at the University at Buffalo are conducting some of the most comprehensive experiments ever attempted to develop methods of evaluating and designing steel buildings so that they will be less vulnerable to collapse during strong earthquakes.

Online service lets blind surf the Internet from any computer, anywhere
Visions of future technology don't involve being chained to a desktop machine. People move from home computers to work computers to mobile devices; public kiosks pop up in libraries, schools and hotels; and people increasingly store everything from e-mail to spreadsheets on the Web.
Rubber 'Snake' could help wave power get a bite of the energy marketA device consisting of a giant rubber tube may hold the key to producing affordable electricity from the energy in sea waves.
Tongue-controlled system assists individuals with disabilitiesA new assistive technology developed by engineers at the Georgia Institute of Technology could help individuals with severe disabilities lead more independent lives.
Solution to high energy costs could lie undergroundSandia National Laboratories researcher Georgianne Peek thinks a possible solution to high energy costs lies underground. And it's not coal or oil.
Chip-cooling technology achieves 'dramatic' 1,000-watt capacityResearchers at Purdue University have developed a technology that uses "microjets" to deposit liquid into tiny channels and remove five times more heat than other experimental high-performance chip-cooling methods for computers and electronics.
Simple insulation could combat heat, cold and noiseAround the world, an estimated one billion people--mostly in rural villages and the shanty towns surrounding developing-world cities--live in houses whose roofs are nothing more than thin sheets of corrugated metal. These houses become unbearably hot in the summer, freezing in the winter, and deafeningly noisy when heavy rains pound on the bare metal.

'Edible optics' could make food safer
Imagine an edible optical sensor that could be placed in produce bags to detect harmful levels of bacteria and consumed right along with the veggies. Or an implantable device that would monitor glucose in your blood for a year, then dissolve.
