By using raw data from Multi Slice Computerized Tomography (MSCT) and processing it through sophisticated software on high performance computer systems, Malaysian entrepreneur Mathavan (Matt) Chandran hopes to largely negate the need to slice open bodies at autopsy. His digital autopsy software exploits the power of existing 2D and 3D imaging and visualization equipment to observe and investigate the human body using high definition imagery. Chandran, CEO of iGene, a subsidiary of the InfoValley Group, believes that reducing family trauma and “placating religious sensibilities” are key driving factors in move toward minimally invasive autopsies. Other benefits include secure retrieval of data, both binary and 3D imaging, from central servers as well as the ability for law courts, forensic centers and hospitals to easily access that data. There is also the capacity to gear the digital autopsy platform to educating medical professionals and students in simulated diagnostics. Whilst au...

In what at first glance seems like a terrible sense of direction, in March students from the University of Washington fired rockets from kites and balloons at an altitude of 3,000 ft (914 m) straight into the ground at Black Rock, Nevada: a dry lake bed in the desert 100 mi (160 km) north of Reno. This may seem like the ultimate in larking about, but it's actually a serious effort to develop new ways of collecting samples from asteroids. The test was part of the “Sample Return Systems for Extreme Environments” project. The idea is to find cheaper, more efficient ways of collecting samples from asteroids and hazardous areas on Earth, such as volcanoes and nuclear disaster zones, by using penetrators instead of soft landers or ground crews to hammer out sample cores. According to the team, this would result in lower cost than soft landing techniques by reducing the velocity and vehicle mass needed to gather the sample, minimizing damage on impact, as well as being mechanically s...

Graduate student Ackeem Ngwenya has combined the 6000 year-old wheel with modern materials to develop a new type of all-terrain wheel assembly that switches from narrow to wide tread at the turn of a screw. His Roadless wheel system, while envisioned for rural applications in his native Malawi, has the potential to be as big a change to road (and off-road) transport as was the introduction of anti-lock braking. We've all done it. Before embarking on a long driving trip on smooth-surfaced interstate highways or other roads of national importance, we'll raise the tire pressure to boost the gas mileage a bit. Stuck in the snow, mud, or sand? Let some pressure out of the tires to increase the contact area, while at the same time increasing the chances that the now floppy tire will grab hold. However, the benefits of trying to change the aspect ratio of a tire by simply changing pressure are rather minor, and often associated with a significant loss in tire lifetime. The Road...
