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
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
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
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
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
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
Storing data on magnetic tape might sound delightfully retro, but it’s actually still widely in use for archival purposes thanks to its high data density. Now researchers at the University of Tokyo have made magnetic tape using a new material, which al… Continue reading New magnetic tape tech makes data storage resistant to interference
Advances in technology have allowed for some high-tech ways to monitor air quality, from satellites that orbit the Earth to art installations that light up when pollutants are low. Scientists at the University of Utah have come up with a relatively low… Continue reading Magnetic leaves could see trees used as low-cost air quality monitors
Astronomers have detected the strongest magnetic field ever observed in the universe. Studying powerful X-ray signals coming from a neutron star, the team calculated that its magnetic field is tens of millions of times stronger than any ever created in… Continue reading Astronomers detect strongest known magnetic field in the universe
Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. The find could be a step towards making electronic components out of common materials that might not otherwise be suitable… Continue reading Non-magnetic material made magnetic using electricity for the first time
