It's the most basic of ways to find out what something does, whether it's an unmarked circuit breaker or an unidentified gene -- flip its switch and see what happens. New remote-control technology may offer biologists a powerful way to do this with cells and genes. A team at Rockefeller University and Rensselaer Polytechnic Institute is developing a system that would make it possible to remotely control biological targets in living animals -- rapidly, without wires, implants or drugs. Researchers experimented with different configurations for their remote control system, and they found the best relies on an iron nanoparticle (blue), which is tethered by a protein (green) to an ion channel (red).
