The folks at Backyard Brains have developed a device called RoboRoach that lets you control the movement of a cockroach with your iPhone! With the RoboRoach you can control a single insect, but what if you had control of an entire swarm? One researcher is trying to develop such technology to aid in search-and-rescue missions.

Using fMRI, scientists have located a part of the brain – just above each of the ears – that responds to quantities. It allows us to look at objects and quickly tell how many there are. This ability maxs out at five objects for most people, but anything less than that and we can quickly tell how many objects there are without even counting thanks to this region of the brain.

NPR – Don’t Call It A Mind-Meld: Human Brains Connect Via Internet. Using electroencephalography (EEG) and transcranial magnetic stimulation (TMS), researchers were able to have one person’s thoughts control another person’s actions. In this case, the subjects (who were also the researchers) were only playing a video game and pressing a button to fire, but still – very cool!
