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.
Ant Lab's Adrian Smith (previously) writes, "No one had ever filmed how ants inject venom when they sting something. I study ants and I make videos, so I went to work on getting that footage. It involved filming something smaller than a human hair moving faster than the blink of an eye. But, I got […]

Above is a three-millimeter long maggot launching itself into the air for a distance of up to 36 times its body length. Researchers from Duke University and their colleagues studied how these larvae of gall midges leap between plants with the greatest of ease, even rivaling some jumping insects with legs. Their research could have […]
Want to make a hit? The right software is out there for anyone, but any music producer will tell you that finding the right sound can still take time and talent. Still, the right tools are a great shortcut, which makes this Synth & Sound Pack Bundle absolutely priceless. And now that it’s on sale […]
Let’s face it: People at the gym aren’t bragging about their headphones. If they were that great, they’d be listening to them instead of talking about them. So while we’re sure those new PowerBeats Pro earbuds are something special, why would you shell out $250 for a tiny pair of speakers when comparable ones are […]
Big companies take on big projects. When they do that, they need a project manager to lay out a roadmap for the entire team – and they’re typically willing to pay a big paycheck to the person who can fill those shoes. So what does it take to become a project manager? If you don’t […]
