The GRIT Freedom Chair takes the wheelchair mountain biking

By - November 15, 2014 12 Pictures
The wheelchair provides invaluable mobility to those with disabilities, but there are countless places where it can't go. Trails, parks, beaches, woods …without a paved road or structured pathway, the wheelchair can quickly find itself out of its element. The GRIT Freedom Chair updates wheelchair design – well not technically wheelchair, but "recreational device" – with all-terrain capabilities. Part mountain bike, part (recreational) wheelchair, the Freedom Chair opens up a new world of exploration. Read More

Coating makes swallowing batteries safer for curious kids

By - November 5, 2014 2 Pictures
It can be a herculean task to get kids to eat their vegetables, but they'll happily chow down on things they aren't supposed to. If one of those things is a button battery, serious injuries can result in the form of burns to the esophagus or tears in the digestive tract. Researchers may not have found a way to stop kids swallowing button batteries, but they have found a way to make such culinary no-nos safer. Read More

Measurable virtual reality reveals robots' intentions

By - November 3, 2014
Imagine if you were trying to develop an autonomous robot, and it continually made a mistake but you couldn't tell why. Ultimately, you might end up having to review all the lines of code that made up its programming, hoping that the error would just jump out at you. In order to avoid such scenarios, MIT's Ali-akbar Agha-mohammadi and Shayegan Omidshafiei have created a system known as measurable virtual reality (MVR). It projects a robot's perceptions and intentions onto the floor, so that designers can see what it's thinking. Read More

MIT's Chisel system saves power by allowing computers to make mistakes

By - October 31, 2014
You may have heard the expression, "Work smarter, not harder." When applied to humans, it means (partially) that we should do our best work on the tasks that are the most important, instead of wasting time and effort by going all out on every task. Well, that principle is now also being applied to computers. Using MIT's new Chisel system, computers are saving power by delegating less-critical tasks to less-dependable lower-energy hardware. This means mistakes may be made on those tasks, but that's OK. Read More

MIT "microwalkers" stroll across cell surfaces to seek out target areas

By - October 27, 2014 2 Pictures
Ever wonder how a germ knows where to attack the body or how a white blood cell knows where to counter attack? How bacteria find food? Or how cells organize themselves to close a wound? How can something so simple do things so complex? A team of MIT researchers is seeking the answers as they develop "microwalkers" – microscopic machines that can move unguided across the surface of a cell as they seek out particular areas. Read More

Electrodialysis identified as potential way to remove salt from fracking waste water

By - October 26, 2014 2 Pictures
Fracking is a highly controversial and divisive issue. Proponents argue that it could be the biggest energy boom since the Arabian oil fields were opened almost 80 years ago, but this comes at a serious cost to the environment. Among the detrimental effects of the process is that the waste water it produces is over five times saltier than seawater, which is, to put it mildly, not good. A research team led by MIT that has found an economical way of removing salt from fracking waste water that promises to not only reduce pollution, but conserve water as well. Read More

MIT's new cement recipe could cut carbon emissions by more than half

By - September 28, 2014
As one of our most relied upon construction materials, concrete makes a significant contribution to our overall carbon emissions. Calcium-based substances are heated at high temperatures to form the cement, a process that produces carbon dioxide. But by slightly altering the quantities of materials used, scientists from MIT have uncovered a new method of cement mixing that could reduce these emissions by more than half. Read More
