Magnets used to turn specific brain circuits off and on at will

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

World’s strongest resistive magnet fired up in China

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

Squid-skin-inspired screen displays encrypted images using only magnets

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

‘Nanowarming’ process a game-changer for organ transplantation

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

Mind control magnets modify appetite and social behavior

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

NASA video: Solar storms are as impressive as the auroras they caused

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

Would we exist if Earth’s magnetic field hadn’t collapsed 500m years ago?

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?

Graphite platform levitates with no need for external power source

Magnetic levitation is used to float everything from lightbulbs to trains, with varying levels of success, but usually it requires a power source. Now, scientists in Japan have developed a way to make a floating platform that requires no external power… Continue reading Graphite platform levitates with no need for external power source

Metal scar found on world-destroying star after its reign of terror

In a few billion years the Sun will destroy the solar system’s inner planets – and if it’s lucky it might get a big cool scar to brag about. That’s what happened to a white dwarf that astronomers have just found, which seems to have a bizarre metal sca… Continue reading Metal scar found on world-destroying star after its reign of terror

Altermagnetism: New form of magnetism discovered in common materials

Scientists have confirmed the existence of a strange new form of magnetism. Hiding right under our noses, the team says that “altermagnetism” can be found in everyday materials and could have major technological uses.Continue ReadingCategory: ScienceTa… Continue reading Altermagnetism: New form of magnetism discovered in common materials
