Magnetic fields are all around us. We can’t really feel or see them ourselves, per se, but we can map them with the right hardware, like this device built by …read more Continue reading Building A Device To Map Magnetic Fields
Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength everywhere …read more Continue reading Measuring Local Variances in Earth’s Magnetic Field
Before the digital age, when transistors were expensive, unreliable, and/or nonexistent, engineers had to use other tricks to do things that we take for granted nowadays. Motor positioning, for example, …read more Continue reading Investigating Electromagnetic Magic in Obsolete Machines
Researchers have developed a gene therapy technology that uses magnetic fields to switch groups of neurons on and off, controlling brain circuits affected by Parkinson’s disease. In addition to Parkinson’s, the tech could be used to treat conditions as… Continue reading Magnets used to turn specific brain circuits off and on at will
Scientists in China have developed the world’s strongest resistive magnet, which produced a steady magnetic field of 42 Tesla (T). The system could improve devices that use magnets, as well as enable a range of new experiments that probe electromagneti… Continue reading World’s strongest resistive magnet fired up in China
Inspired by the color-changing skin of squids and other cephalopods, researchers have developed a flexible screen capable of storing and displaying encrypted images without using electronics – just tiny magnetic particles.Continue ReadingCategory: Tech… Continue reading Squid-skin-inspired screen displays encrypted images using only magnets
A new two-step process that safely rewarms frozen tissues using nanoscale magnetic rods could help preserve donor organs long-term. The procedure provides an alternative to current time-limited methods and paves the way for more life-saving transplanta… Continue reading ‘Nanowarming’ process a game-changer for organ transplantation
Researchers have developed a remote, non-invasive method of selectively controlling neurons in the brain using magnetic fields. The technique opens the door to a greater understanding of brain function and, potentially, new treatments for disorders.Con… Continue reading Mind control magnets modify appetite and social behavior
While millions of people who couldn’t normally see the aurora borealis took in the recent color-filled spectacle in the night sky, NASA’s Solar Dynamics Observatory was looking straight at the sun to catch all the action. The fiery footage is well wort… Continue reading NASA video: Solar storms are as impressive as the auroras they caused
The Earth’s magnetic field is vital for life – without it, the Sun’s radiation would sterilize the planet. But a new study suggests we wouldn’t be here at all if that magnetic field hadn’t almost completely collapsed half a billion years ago.Continue R… Continue reading Would we exist if Earth’s magnetic field hadn’t collapsed 500m years ago?
