  • Brazilian researchers have created a new two-dimensional material called hematene, which is made up of sheets of iron ore just three atoms thick. And as is often the case with 2D materials, hematene seems to have different properties to its regular form.
  • Scientists are coming up with some creative ways to fight cancer. Researchers at the University at Buffalo have developed new kinds of nanoparticles that can infiltrate, heat up and kill cancer cells more effectively and efficiently than similar methods.
  • Harvard scientists have led an international team to develop a new surface that can reconfigure its shape, stickiness or slipperiness on demand, through the application of a magnetic field.
  • ​Some day, it may be possible for tiny squishy robots to make their way through people's bodies, without being tethered to an external power supply or control unit. We've recently gotten a step closer to that being a reality, thanks to 3D-printing tech that produces magnetically-responsive devices.

    ​If wines such as cabernet sauvignon contain high amounts of chemical compounds known as alkylmethoxypyrazines (MPs), their fruity/floral bouquet can be overwhelmed, resulting in an off-putting flavor and aroma. Now, scientists have used magnetic nanoparticles to remove MPs from wine.
  • ​Some serious cyclists have taken to using breathing strips or even stents to hold their nostrils open, in order to increase the amount of air that they're able to take in through their nose. Well, a new set of cycling glasses does the same thing, but using magnets.
  • ​Regular readers of New Atlas may recall Maglock mountain bike pedals, which use magnets to keep the rider's feet secured to the pedals. Well, if a new Kickstarter campaign is successful, Maglock could be in for some competition, in the form of the Austrian-designed magped pedals.
  • ​Major internal bleeding is a very serious condition that requires immediate attention, and it's difficult to treat non-surgically. Scientists from Russia's ITMO University are working on an effective means of doing so, however, in the form of injectable magnetic nanoparticles.
  • Curtains or blinds might eventually get the flick in favor of smart windows. Now a team of engineers has demonstrated a new design. Dubbed Large-Area Fluidic Windows (LaWin), the system uses iron particles suspended in liquid to block sunlight at different levels, and harvest its heat energy.
  • Imagine if your car could feel pain and alert you when it takes damage. The US Army is funding research to make that a reality, with vehicles outfitted with a smart material that senses damage the way nerves sense pain, relaying a damage report to help with maintenance and repairs.
  • A team from the University of Washington has developed a system that lets passcodes be stored in your clothes without electronics, courtesy of a patch of magnetic fabric that can be read by sensors at a door or vending machine.
  • ​For over a decade, Danish manufacturer Reelight has been making bicycle lights that are powered by magnets mounted on the bike's spokes. Now, the company has set about making its lights more compact and more powerful, with the CIO.
