Instead of the usual carbon atoms, artificial graphene is made from crystals of traditiona...

Graphene is truly a 21st-century wonder material, finding use in everything from solar cells to batteries to tiny antennas. Now, however, a group of European research institutes have joined forces to create a graphene knock-off, that could prove to be even more versatile.  Read More

Smart dust. Utility fog. Programmable matter. Grey and blue goo. Cooperating swarms of micron-sized devices (motes) offer completely new solutions and capabilities that can hardly be imagined. However, cooperation requires communication, and conventional radio or optical networking simply isn't practical at this size. Now researchers at Georgia Tech have invented a plasmonic graphene nano-antenna that can be efficiently used at millimeter radio wavelengths, taking one more step toward smart dust.  Read More

The SaveOneLife system

Boot insoles can turn a pair of really uncomfortable brogues into podiatric clouds that can take a long hike and remove the foot ache. Now, Lemur Studio Design based in Bogota, Colombia, has come up with a concept for insoles that won’t just save your instep, but could save your life. A submission to the World Design Impact Prize 2013-2014 competition, SaveOneLife is a wearable mine detector that fits in a shoe and warns the wearer if and where a potentially deadly landmine might lurk nearby.  Read More

If you were asked to think of something microscopic that moves quickly, chances are that sperm would be the first thing to come to mind. The tiny reproductive cells are able to swim as fast as they do thanks to their long whip-like tails, known as flagella. So, imagine how helpful it might be if sperm-like machines could be used for applications such as delivering medication to targeted areas of the body. Well, that's what scientists at the University of Illinois are in the process of making possible, with the creation of their heart cell-powered "bio-bots."  Read More

A new type of carbon nanotube sponge containing sulfur and iron could help clean up oil sp...

A new type of carbon nanotube (CNT) sponge that contains sulfur and iron has been developed and is proving to be more effective at soaking up water contaminants, such as oil, fertilizers, pesticides and pharmaceuticals, than previously seen. The magnetic properties of these nanosponges also make them easier to retrieve from the environment once the clean-up job is done.  Read More

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

Scientists at the University of Pennsylvania have grown liquid crystal flowers, making it possible to create lenses as complex as the compound eye of a dragonfly. When perfected, the technology could allow the growth of lenses on curved surfaces, and structures to be assembled out of liquid crystals to build new materials, smart surfaces, microlens arrays and advanced sensors.  Read More

Bioinspired magnetically propelled helical microswimmers could deliver drugs at the right ...

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

We're still a long ways away from the self-drying clothing seen in Back to the Future II, but we may have a useful alternative in the form of a piece of clothing that never gets wet to begin with. Young entrepreneur Aamir Patel has developed the Silic shirt, which is made from a hydrophobic fabric that repels liquids away from it like a force field to keep it from getting wet.  Read More

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM radio transmitter.  Read More
