Review: MagLOCK magnetic pedals should attract a certain crowd

Many mountain bikers swear by the pedalling efficiency of so-called clipless pedals, in which a steel cleat on the bottom of each shoe engages a spring-loaded mechanism in the pedal. Some other riders, however, just don't like the idea of being "snapped in" like that. It was with this in mind that cyclist Dave Williams created MagLOCK pedals. They're non-threatening platform pedals, that keep the user's feet in place using magnets instead of mechanisms. We recently had a chance to try them out, and generally liked what they had to offer.

Material that could revolutionize memory storage is magnetic, but not as we know it

Using a type of magnetic insulator material that normally doesn’t conduct electricity, scientists working at Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory have shown that electric currents can still be made to flow along the borders of the grains within the material. This latest research not only validates a long-held belief that magnetic insulators could be used to conduct electricity, but offers a more tantalizing possibility of creating highly-efficient magnetic memory devices.

ARC reactor design uses superconducting magnets to draw fusion power closer

Fusion power can seem a bit like the last bus at night; it's always coming, but never arrives. MIT is working to change that with a new compact tokamak fusion reactor design based on the latest magnetic superconductor technology. The ARC (affordable, robust, compact) reactor design promises smaller, cheaper reactors that could make fusion power practical within 10 years.

Magnetism generated in non-magnetic metals

By subtly altering certain quantum interactions in matter, scientists from the University of Leeds have shown for the very first time how to generate magnetism in metals that aren’t normally magnetic. Synthetic magnets made using this technique may one day reduce our reliance on rare or toxic metals in such things as wind turbines, computer hard drives and magnetic field medical imaging devices.

MagKey uses magnets to stop keys jangling

Occasionally an invention comes along that promises to change mankind fundamentally, enable us to grow as a species, and expand our capabilities beyond what was previously thought possible. MagKey isn't one of those kinds of inventions at all. It simply uses magnets to stop keys from jangling, but we're still impressed.

IBM sets new tape storage record

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.
