New water-purifying synthetic nanoscavengers can be removed from water magnetically (Photo...

According to a joint World Health Organization/UNICEF report issued this week, an estimated 768 million people relied on unimproved drinking-water sources in 2011, with 185 million of these relying on surface water to meet their daily drinking-water needs. WHO and UNICEF have set a 2030 target for everyone to have access to a safe drinking-water supply and new water-purifying “nanoscavengers” developed by researchers at Stanford University could help achieve this goal.  Read More

A 300-micrometer microgripper at the opening of a cathether

When procuring tissue samples for medical diagnosis, doctors have been confined to bulky and invasive forceps. But with recent successful experiments in pigs, we may see doctors switching from the single forceps to hordes of a thousand "microgrippers." These metal discs, each only 300 micrometers in size, are designed to snip bits of tissue when introduced en masse into the body and then be easily retrieved by a doctor. Their small size, added to the fact that they need no batteries, tethers or wires, belies their complexity and autonomy in function, which could allow the microgrippers to provide diagnoses earlier, more easily, and with less trauma.  Read More

Vibromag Cables could find use in security fences such as this one

Things might be getting a little more difficult for the James Bonds and Jason Bournes of the world. A new system developed by Prof. Uwe Hartmann at Germany’s Saarland University utilizes the Earth’s magnetic fields to instantly determine when and where a security fence has been breached.  Read More

The Magnetic Spirit shelving system - art installation or usable furniture?

The Magnetic Spirit shelving system is a concept design from Benoît Bayol and Christophe Bricard. Lying somewhere between carpentry and Cubism, it uses a patented magnetic fixing system to allow the creation of different layouts – and to change the layout at will depending on your mood at any given time.  Read More

The Koala Bottle system uses magnets to hold its bottle in place on the user's bike

The standard bicycle water-bottle-and-cage system is pretty tried and trusted. That said, at one time or another, just about every cyclist has dropped their bottle on the road when they didn’t put it back in the cage properly ... or perhaps they’ve even wiped out, because they were distracted by trying to remove or replace the bottle. That’s why Anthony Goldman created the Koala Bottle system, which uses magnets to keep the bottle attached to the bike.  Read More

The Magnetyze smartphone-charging system connects the phone to the charger using nothing b...

Phone chargers may not be way up there on peoples’ lists of troublesome devices, but if the things can be made simpler ... hey, why not? BuQu Tech’s new Magnetyze system attempts to do just that, with a magnetic case/charger combo. Users just place their Magentyze case-clad smartphone near the slab-like desktop charging platform, and it will be magnetically sucked into place and charged up – no cords need to be plugged in.  Read More

ONE: multi-ringed calendar and magnetic designer corporate play-thing

For much of the socio-economic West, new year is set to roll around in approximately 14 days. For South Korean designer Jeong Yong, the rolling around is likely to occur literally as well as figuratively, being that Yong is the designer of the ONE Table Calendar, a multi-ringed calendar and magnetic designer corporate play-thing.  Read More

A prototype of the remote magnetic gears system

Wireless charging systems seem like an easy way to keep electric cars running. You just drive up to a charge point and let the system beam power to your battery without ever having to step out into the cold and rain. However, these systems require high-frequency electromagnetic fields that can interfere with electronics and pose potential health hazards. To keep the hands-free advantages of wireless, yet get rid of the high-frequency fields, physics professor Lorne Whitehead and his team at the University of British Columbia (UBC) have developed an electromechanical vehicle charger that uses “remote magnetic gears”s instead of electrical coils  Read More

Omaha Beach in Normandy, France, as it appears today (Photo: Anton Bielousov via Wikipedia...

Sandy beaches are a delight for swimmers, surfers, sailors, and people strolling down the boardwalk. A horde of beautiful shells and buried coins (not to mention the occasional dropped ring) awaits the skilled beachcomber. Beach sand also carries within it a variety of traces of the history of that beach. A prime example is the magnetic sands of Normandy.  Read More

The oil and water separation technique uses permanent magnets immersed in a reservoir cont...

Possibly the only good thing to come out of the Deepwater Horizon disaster is the subsequent increase in research into finding more effective ways to clean up oil spills, including such initiatives as the X PRIZE Foundation's Wendy Schmidt Oil Cleanup X CHALLENGE. Joining the list is a new method devised by researchers at MIT who propose separating oil and water using magnets. The new technique would allow the oil to be recovered to help offset the costs of the cleanup operation.  Read More
