As I discovered when reviewing the Minty Geek Electronics Lab a while back, experimenting with circuit building can be a great deal of fun. There was one particular project in this kit that made use of the human body to complete a circuit, with a simple lie detector test being the end result. With their Makey Makey open source hardware project, Jay Silver and Eric Rosenbaum have taken such touch interaction to a much more entertaining and inventive degree. Everyday objects like bananas, coins, and even Play-Doh can be transformed into a computer keyboard key or mouse click to control onscreen gaming action, play software-based instruments or type out short messages.

As machines get more and more sophisticated, the mental capacity of their human overlords stays at a static (albeit seemingly impressive) level, and therefore slowly starts to pale in comparison. The bandwidth of the human brain is not limitless, and if an overloaded brain happens to be overseeing machines carrying out potentially dangerous tasks, you can expect trouble. But why had we built the machines in the first place, if not to save us from trouble? Brainput, a brain-computer interface built by researchers from MIT and Tufts University, is going to let your computer know if you’re mentally fit for the job at hand. If it decides your brain is overloaded with tasks, it will help you out by handling some of them for you. Read More
A group of researchers at MIT and Georgia Tech has built a robotic arm that can automate whole-cell patch clamping, a complicated technique that normally requires great manual dexterity and takes researchers months to master. Once streamlined, this technology will monitor and record the electrical signals generated by the neurons in a living brain, to help uncover the secret inner workings of the human mind - or at least, in the not-so-distant future, of a lab rat's.

People who saw the 1984 film 2010: The Year We Make Contact might remember a scene in which Roy Scheider, while describing the orientation of the spaceship that he’s aboard, picks up a pen and places it in mid-air in front of himself. While that effect was actually accomplished using a sticky-sided pen and a very clear plate of glass, the same sort of thing is now actually possible – if you’re in the right place, and positioning the right object. The place is MIT’s Media Lab, and the object is a small plastic-coated spherical magnet called ZeroN. Users can physically place it anywhere within a specified three-dimensional block of “anti-gravity space,” then watch as it stays in place when they let it go. It can also move through the air on its own, and even function as a virtual movie camera. Read More
In a natural phenomenon known as margination, platelets and leukocytes (white blood cells) within the bloodstream move towards the sides of blood vessels and adhere to them. It occurs at wound sites, during the early stages of inflammation. Recently, a team of researchers from the Massachusetts Institute of Technology and the National University of Singapore have put that process to work in a microfluidic device that could be used to cleanse the blood, perhaps acting as a treatment for bacteria-related blood disorders such as sepsis.

MIT PhD student David Mellis has designed and built a fully operational mobile phone, named the DIY Cellphone, using about US$150-worth of parts. Read More
As fruit matures, it releases a gas known as ethylene, that causes the ripening process to begin. Once that process is under way, more ethylene is released, kicking the ripening into high gear. Currently, produce warehouses use expensive technologies such as gas chromatography or mass spectroscopy to measure ethylene levels, in order to gauge the ripeness of fruits that are in storage. A scientist from MIT, however, is developing small, inexpensive ethylene sensors that could be used in places such as supermarkets. There, they could let shopkeepers know which batches of fruit need to sold the soonest, in order to minimize spoilage. Read More
The two-hundred and ninety-five feet (ninety meter) tall Building 54 on MIT's Cambridge campus has become the canvas for a number of carefully planned and daringly executed visual displays over the years, not strictly allowed by the administration but often looked upon with some appreciation. The building is home to the Institute's Department of Earth, Atmospheric, and Planetary Science (EAPS) and has a host of meteorological instruments and radio communications equipment on its roof - but its the grid-like windows to the front that have become the main attraction to hackers, as they are known. The latest hack is the successful realization of a long-standing challenge, a huge playable game of Tetris. Read More
Glass has a unique look - despite its clarity you can tell there is a material there by the way it reflects light, and that it isn't plastic or crystal. Glass, however, carries problems, like glare, fogging, and collects dirt. A group of MIT researchers has found a new way to create arrays of conical micron-scale surface nanotextures to produce glass that is self-cleaning, non-glare, and non-fogging. The researchers believe the nanotextured surface can be made at low enough cost to be applied to optical devices, the screens of smartphones and televisions, solar panels, car windshields and even windows in buildings.

Probably the simplest way to describe an artificial hip would be to say that it’s a ball attached to a stem. The stem is often fastened to the open end of the femur using a glass-like polymer known as bone cement, while the ball takes the place of the original hip bone’s ball joint, rotating within a corresponding implant in the socket of the pelvis. Although problems can occur at that ball-and-socket interface, they can also result when the bone cement cracks, causing the stem to detach from the femur. Scientists at MIT, however, have developed a new type of nanoscale film coating, designed to keep that from happening. Read More
