The MAGDRIVE project is tasked with developing a touchless transmission

Satellites and other spacecraft, like most machines, have parts that move against one another. Unlike most machines, however, they operate in extremely cold conditions, their power source is often very limited, and lubricating or repairing them are not exactly easy tasks. It is for these reasons that researchers at Spain’s Universidad Carlos III de Madrid (UC3M) are coordinating the three-year MAGDRIVE project – an international effort to create a mechanical transmission with no touching parts, that doesn’t need any lubrication.  Read More

The 3Dxy electric guitar pickup system registers string vibration on two axes to offer a r...

The incredible guitar virtuosity from the likes of Joe Satriani, Eric Johnson and Stanley Jordan all rely on their string-picking proficiency being registered by the instrument's pickups. These vibrations are then transformed into electrical signals and sent off to an amplifier for our listening pleasure. Using such a setup, string movement can only be read on one axis, the horizontal. The 3Dxy pickup system reads each string twice, on both the horizontal and the vertical and is said to result in a rich, surround sound effect called natural stereo.  Read More

Stick an iPad on your fridge with the FridgePad

Computers have already conquered the study and the lounge room and have been making steady inroads in their assault on the kitchen with devices such as Internet capable fridges and digital recipe readers. As soon as the iPad was released, more than a few people were pondering its potential as a kitchen computer to provide the functionality of these devices and more. Heck, a few creative types even mounted iPads into their cupboard doors. For those of you who like the idea of a kitchen iPad but perhaps aren't that handy with a jigsaw, you might try the FridgePad.  Read More

Graphene, the one-atom-thick material made up of a honeycomb lattice of carbon atoms, has produced yet another in a long list of experimental surprises. Its remarkable properties have already got researchers excited regarding its applications for faster computers, cheaper and more efficient batteries and vastly higher density mass data storage. Now researchers have reported the creation of pseudo-magnetic fields far stronger than the strongest magnetic fields ever sustained in a laboratory – just by putting the right kind of strain onto a patch of graphene. The breakthrough could have far reaching scientific applications.  Read More

Fotopro's RM-110 tripod

Chinese photographic accessory company Fotopro has developed a heavy-duty flexible tripod that has interchangeable feet. The Fotopro RM-110 is comprised entirely of adjustable joints and comes standard with four sets of feet: spiked, suction, rubber and magnetic. We’ve tried all four and they offer a stable mount on any surface, but particularly so on flat or metal surfaces - the suction cups and magnetic feet are capable of affixing so solidly they can handle the weight of even a middleweight pro video camera. We’re predicting the USD$60 RM-110 will become a standard fixture in the kit of every photographer and videographer.  Read More

In the future, your refrigerator might keep your food cold by using a magnet. Not only would it use less power and run quieter than your current fridge, but it also wouldn’t contain any hydrofluorocarbons, gases which can add tremendously to the greenhouse effect if not properly disposed of. It all comes down to something called the magnetocaloric effect, wherein a changing magnetic field within a material causes it to get colder. It definitely holds promise, although scientists first have to figure out just how the thing works.  Read More

The sensor uses maglev to analyze sample density

When one thinks of magnetic levitation, or maglev, one generally thinks of insanely fast floating trains or possibly even levitating cans and bottles. Well, scientists are reporting the development of a new use for the technology as an inexpensive sensor for analyzing food, water and other beverages.  Read More

Use the force Lu.. ah, Magnetic Suspension Device

Ever wanted to levitate a can or bottle inside an illuminated ring? Of course you have. Well, this device from Chinavasion uses the force to do just that. Unfortunately it uses force of the magnetic variety and not the Jedi kind, but the snappily named Magnetic Suspension Device is sure to be a conversation starter nonetheless.  Read More

Gorillapod goes magnetic

Gorillapod's camera tripods have become a common sight since they were released a few years back and there's a good reason for that - it's a great idea. Now Gorillapod designer Joby has announced a new addition to the range - the Gorillapod Magnetic - which incorporates magnets into the feet of the flexible tripod allowing it to be anchored to any magnetic surface.  Read More

Stanford Professor Shan Wang and graduate student Richard Gaster, left, have developed an ...

Extremely sensitive nanosensor chips are being developed by Stanford University researchers in an attempt to detect the early signs of cancer, called biomarkers, in humans. The researchers say their sensor is around 1,000 times more sensitive than current technology and is accurate regardless of which bodily fluid is being analyzed. It can also detect biomarker proteins over a range of concentrations three times broader than any existing method. It is forecast that earlier detection of cancer biomarkers will lead to improved survival rates among cancer sufferers.  Read More
