ananyo writes "A toy quadcopter can be steered through an obstacle course by thought alone. The aircraft's pilot operates it remotely using a cap of electrodes to detect brainwaves that are translated into commands. Ultimately, the developers of the mind-controlled copter hope to adapt their technology for directing artificial robotic limbs and other medical devices." From the paper (PDF) abstract: "... we report a novel experiment of BCI controlling a robotic quadcopter in three-dimensional (3D) physical space using noninvasive scalp electroencephalogram (EEG) in human subjects. We then quantify the performance of this system using metrics suitable for asynchronous BCI. Lastly, we examine the impact that the operation of a real world device has on subjects’ control in comparison to a 2D virtual cursor task. Approach. ... Individual subjects were able to accurately acquire up to 90.5% of all valid targets presented while traveling at an average straight-line speed of 0.69 m s^(1)." This also appears to be the first time a Brain-Computer Interface was used to operate a flying device in 3D space. Also, there are several additional videos showing people operating the quadcopter.

In Michigan, you can smoke marijuana and still drive a car. That's what the Michigan Supreme Court ruled this Tuesday, albeit on a technicality. Though Michigan has a zero-tolerance policy for driving "under the influence" of marijuana, it also has a law on the books that exempts medical marijuana users from any sort of persecution for its use, and so the court had to decide which of the two laws it wanted to uphold.

Since Michigan doesn't actually specify an amount of marijuana in a user's system that impairs driving judgement enough to be considered "under the influence," simply outlawing drugged driving altogether went too far, argued the court. If the state could prove that a driver was under the influence, the court decided, then...

The FDA is investigating the safety of a surgical robot that was used in 367,000 procedures last year, following the documentation of a slew of potentially dangerous errors, reports the Associated Press. Intuitive Surgical's da Vinci system, a three- or four- armed robot remotely controlled by surgeons, is now in nearly a quarter of US hospitals, but an increasing number of reported potential mishaps — about 500 since last year — has caught the FDA's attention. Though there's no official results of the investigation yet, an FDA spokesperson told the AP that the increased quantity of incident reports may simply be a matter of better practices by doctors as they become more aware of the new tool. We've reached out to Intuitive Surgical...

It's a bit longer than my normal videos, but this vice documentary is a very interesting look at another culture's relationship with cannabis. Be sure to turn on subtitles by clicking the "cc" button in the bottom right of the video.
