Magzet brings magnet connections to any audio jack

One of the least exciting pieces of technology on a smartphone is the 3.5 mm audio jack. There's not a lot of room to make changes there, but Magzet is aiming to do some innovating by turning any audio jack into a magnet connector. It's a simple change, but one that promises to make plugging in audio devices easier, and a whole lot cooler.Read More

Magnetic nanoparticles open blood-brain barrier for delivery of therapeutic molecules

The blood-brain barrier is a highly selective semipermeable barrier running inside almost all vessels in the brain that lets through water, some gases and a few other select molecules, while preventing potentially toxic elements in the blood from entering the brain. Researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine say that currently 98 percent of therapeutic molecules are also blocked by the barrier, but they have developed a technique using magnetic nanoparticles that opens the door for such molecules, thereby also opening the door to new treatments for brain diseases.Read More

Tiny robotic hand-like grippers dissolve in the body after performing task

Creating swarms of soft, robotic hands that can safely dissolve within a living body once they've performed surgical procedures or delivered drugs just got a step closer thanks to work done by John Hopkins University scientists. They've created minute biodegradable microgrippers by adding stiff polymers containing magnetic nanoparticles to soft hydrogels, allowing them be magnetically guided to any location in the body.

Skin-applied foil could give people a sense of "magnetoception"

How would you like to be able to sense magnetic fields? It could come in handy, given that some animals navigate and maintain their spatial orientation by doing so. Well, we've now come one step closer to humans having that ability, too. Scientists from Germany's Leibniz Institute for Solid State and Materials Research, along with colleagues from the University of Tokyo and Osaka University, have developed a thin, flexible magnetoresistive sensory foil that can be applied to a person's own natural skin.

MagLOCK offers a magnetic take on clipless pedals

So-called "clipless" bicycle pedals, in which a steel cleat in the sole of the rider's shoe clicks in and out of a mechanism in the pedal, are very popular with cyclists – they maximize pedaling efficiency, plus they help keep riders' feet from accidentally slipping off the pedals when going over rough terrain. Some riders, however, find them too difficult to quickly snap out of. Additionally, they don't work well with regular, non-cleated footwear. That's why Salt Lake City-based mechanical engineer David Williams has created the MagLOCK bike pedal. Read More

NASA to deploy four spacecraft to study magnetic reconnection

NASA has released a video depicting the initial deployment of an undertaking designed to study a phenomenon known as magnetic reconnection. The launch of the Magnetospheric Multiscale (MMS) mission will see four identical spacecraft deployed from a single Atlas V rocket, set to lift off from cape Canaveral, Florida, no earlier than March next year.

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

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
