Aura turns hand gestures into music

Some take their air guitar playing more seriously than others, but even for those exerting the most energy, those perfectly struck imaginary chords are heard by nobody's ears except their own. Aura, an electronic instrument that translates hand gestures into music, could be just what these highly animated faux musicians need to get a little more reward for their efforts. Read More

Your next fridge could keep cold more efficiently using magnets

The fridge is the most common of common household appliances. Despite improvements in efficiency over the years, they remain one of the biggest users of electricity in the home, relying on chemical refrigerant and a compressor to transfer heat from the inside to the outside of the fridge. GE researchers have now developed a new type of refrigeration technology using magnets that is more environmentally friendly and is predicted to be 20 to 30 percent more efficient that current technology ... and it could be in household fridges by the end of the decade.Read More

Remote-controlled spermbots could be used to fertilize eggs

Hijacking sperm cells to create little robots might seem far out, but that's exactly what researchers from the Dresden Institute for Integrative Nanosciences have done. Their "spermbots" consist of live sperm cells in little tubes, that can be magnetically controlled to move in a desired direction until they reach their destination and do their job – they're currently robust enough to even guide a specific sperm cell to an egg cell. The scientists hope that further development will allow the technology to offer a viable alternative to parents trying to have a child through in-vitro fertilization. When perfected, the spermbots could also be used as a safe means for drug delivery and gene manipulation. Read More

Plant-based magnetic microswimmers to deliver drugs more precisely

If you remember the 1966 science fiction film Fantastic Voyage, you'll recall how miniaturized government agents traveled through blood vessels in a tiny submarine, in their attempt remove a blood clot from a scientist's brain. Synthetic nanomotors that can do the same job have been the subject of numerous research efforts and now University of California, San Diego (UCSD) researchers report that they've created powerful biodegradable "microswimmers" that can deliver drugs more precisely, derived from common plants like passion fruit and wild banana.Read More

Swarm satellite launch marks start of four-year mission

On Friday, ESA began a four-year mission to study the Earth’s magnetic field with the launch of the three-satellite Swarm constellation into Earth orbit. Packed “like sardines” in their fairing, the unmanned spacecraft lifted off at 12:02 GMT (1:02 PM CET) from the Plesetsk space port in northern Russia atop a Rockot launcher.Read More
