IBM sets new tape storage record

By - April 13, 2015 6 Pictures
For many people, tape memory is a dead technology found only on reel-to-reel computers in old 1960s movies. However, it’s still a major storage medium and a new breakthrough by IBM Research and Fuji Film has produced a low-cost particulate magnetic tape with a record density of 123 billion bits of uncompressed data per square inch, which represents 88 times more capacity than 2012's LTO-6 tape cartridge.

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

By - March 26, 2015 1 Picture
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.

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

By - February 24, 2015 1 Picture
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"

By - February 3, 2015 4 Pictures
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

By - November 26, 2014 4 Pictures
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
