Collaborate Disseminate
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
When it comes to the treatment of certain neurological conditions, doctors are increasingly looking to battery-powered implants that stimulate parts of the brain. Now, however, scientists have developed one that’s externally powered by magnetic fields…. Continue reading Tiny battery-free implant could stimulate neurons to treat disorders
Early results presented at the American Stroke Association’s International Stroke Conference in Los Angeles suggest non-invasive magnetic brain stimulation can enhance brain activity in patients after stroke. It is hoped the device could speed up recov… Continue reading Magnetic stimulation enhances brain activity, aiding stroke recovery
As a flat sheet of carbon atoms arranged in a lattice, graphene is pretty simple, and yet it keeps surprising scientists with new properties. For the latest in this long line of breakthroughs, a team from Stanford has shown that graphene arra… Continue reading Twisted graphene exhibits previously-unseen form of magnetism
Magnets as we know them are always solid, but the closest thing we have to a magnetic liquid is a class called of liquids called ferrofluids. Made up of iron-oxide particles suspended in liquids, these materials are only magnetic temporarily,… Continue reading Berkeley Labs creates first fully magnetic liquids
Magnetic hotspots on the Moon might contain clues about how to protect humans from radiation on other planets. Continue reading The Moon Has Tan Lines, NASA Says
