Racing Cars on a PCB
Carl Friedrich Gauss was, to put it mildly, a polymath responsible for a large percentage of the things we take for granted in the modern world. As a physicist and …read more Continue reading Racing Cars on a PCB

“Cosmic magnet” recreated in lab as alternative to rare earths
Rare earth elements are a key part of electronic and mechanical devices, but they’re in short supply. Now, scientists have found a way to recreate a promising alternative – a “cosmic magnet” that normally takes millions of years to form in meteorites c… Continue reading “Cosmic magnet” recreated in lab as alternative to rare earths
Quieter millo air blender uses magnets in place of a regular motor
Five years ago we heard about the compact millo blender, which was reportedly only 25% as loud as a regular blender. Well, the new millo air is claimed to be even slimmer and lighter than its predecessor, and to produce no motor noise at all.Continue R… Continue reading Quieter millo air blender uses magnets in place of a regular motor
Harvard scientists observe new state of matter, a quantum spin liquid
An exotic state of matter originally hypothesized almost 50 years ago has been observed for the first time. Created by Harvard researchers, this material called quantum spin liquid could eventually help improve quantum computers.Continue ReadingCategor… Continue reading Harvard scientists observe new state of matter, a quantum spin liquid
The future of prosthetic limb control may be magnetic
Currently, most powered prosthetic limbs are controlled by electrodes in the user’s residual stump. An experimental new MIT system, however, is claimed to work better by replacing those electrodes with implanted magnetic beads.Continue ReadingCategory:… Continue reading The future of prosthetic limb control may be magnetic
Magnetically guided particles temporarily lower sperm count in mice
When it comes to contraceptives, men typically have to remember to use a condom, or get a difficult-to-reverse vasectomy. There may soon be a new option, however, in the form of injected particles that are magnetically guided to the testes.Continue Rea… Continue reading Magnetically guided particles temporarily lower sperm count in mice
Mahle’s cheap, highly efficient new EV motor uses no magnets
Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It’s nice to have a permanent source of powerful rare earth magnetism in your rotor, because using powered coils instead means you have t… Continue reading Mahle’s cheap, highly efficient new EV motor uses no magnets
Paleomagnetism suggests supercontinent cycle began two billion years ago
Geologists have pieced together an uncertain part of Earth’s ancient history. A team in Australia has found new evidence that suggests the cycle of supercontinents forming and breaking up only started about two billion years ago.Continue ReadingCategor… Continue reading Paleomagnetism suggests supercontinent cycle began two billion years ago
Artificial magnetic texture induced in graphene could boost spintronics
Graphene has a lot of useful properties, but magnetism isn’t one of them – at least, not usually. In a new study led by the University at Buffalo, researchers have managed to induce an “artificial magnetic texture” in the material, which could have maj… Continue reading Artificial magnetic texture induced in graphene could boost spintronics
Ultrasound and magnetism let drug-delivery nanobeads travel upstream
Although various groups are already working on nanoparticles that could be used for directed drug delivery via the bloodstream, most of those particles are designed to “go with the flow.” Now, however, Swiss researchers have created ones that can actua… Continue reading Ultrasound and magnetism let drug-delivery nanobeads travel upstream
