The 1990s nanotechnology dream of tiny robots swimming through our blood stream to treat disease is moving (verrrry) slowly but surely toward reality. In a new milestone, researchers used an external magnetic field to steer microbots through a live mouse's body carrying therapeutic stem cells. From IEEE Spectrum:
..Delivering stem cells typically requires an injection with a needle, which lowers the survival rate of the stem cells, and limits their reach in the body. Microrobots, however, have the potential to deliver stem cells to precise, hard-to-reach areas, with less damage to surrounding tissue, and better survival rates, says Jin-young Kim, a principle investigator at DGIST-ETH Microrobotics Research Center, and an author on the paper....
The team fabricated the robots with 3D laser lithography, and designed them in two shapes: spherical and helical. Using a rotating magnetic field, the scientists navigated the spherical-shaped bots with a rolling motion, and the helical bots with a corkscrew motion. These styles of locomotion proved more efficient than that from a simple pulling force, and were more suitable for use in biological fluids, the scientists reported....
Kim says he and his colleagues are developing imaging systems that will enable them to view in real time the locomotion of their microrobots in live animals.
Snail slime — called an epiphragm — is an incredibly strong yet reversible adhesive. Now, University of Pennsylvania scientists have developed a new kind of glue that employs the same mechanism as the epiphragm. The new material dries like superglue but once wet, it loses its adhesion. For years, scientists have explored adhesions inspired by […]
NASA released this incredible image of the sky that depicts 22 months of X-ray data captured from the International Space Station using the Neutron star Interior Composition Explorer (NICER). From NASA: “Even with minimal processing, this image reveals the Cygnus Loop, a supernova remnant about 90 light-years across and thought to be 5,000 to 8,000 […]
In the realm of rocket geeks and space nerds, filmmakers MaryLiz Bender and Ryan Chylinski have dream jobs. The pair have the equivalent of “backstage passes” to SpaceX, NASA and ULA rocket launches where they capture and share breathtaking videos that convey the power, risk, and thrill of space exploration. The work of their studio, […]
So you cut the cord and got rid of cable? Join the steadily growing club. But while you’re out picking a streaming service, you might find one big blind spot: Local TV and sports, not to mention first-run programming from the big cable networks. Luckily, there’s a throwback way to get it for free: The […]
Even if you feel like AirPods are worth the price tag, you’ve got to admit there’s a certain anxiety that comes with using them. What if I lose them? What if they get wet in the rain? Or drenched in sweat? Or fall into the drink you dropped them into? Shiny tech is great, but […]
With the quick-fix appeal of video games and their own cell phones, it can be tough to keep kids focused on supposedly “educational” toys. And while it may seem counter-intuitive to fight tech with more tech, we’re all in when it comes to the Toybox 3D Printer. We’re not sure if anyone had envisioned a […]
