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.
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, […]
Ziya Tong is a veteran science reporter who spent years hosting Discovery's flagship science program, Daily Planet: it's the sort of job that gives you a very broad, interdisciplinary view of the sciences, and it shows in her debut book, The Reality Bubble: Blind Spots, Hidden Truths, and the Dangerous Illusions that Shape Our World, […]

Heading abroad? Even if it’s just a short trip, there’s a lot to prepare for. Travel can be incredibly rewarding, but it can tricky to navigate different cultures and lodging arrangements – and even trickier to do it cheaply. Before you go shopping for suitcases, here’s our pick for a good first investment: The Ultimate […]
Fried foods are a weakness for many of us. There’s nothing quite like that extra crisp crackle on chicken, fries or onion rings. And for years, our arteries have been paying for the privilege. Lately, the air fryer has been a godsend for those who love the fried stuff but love their body too. If […]
