    What they may also not have mentioned was that, prior to the mice being injected with the retrovirus that used blue light sensitive genes to alter their eyes, they were previously blind (as is genetically common with lab mice). So it's also basically a potential cure for blindness, or potentially a way to allow humans to see other forms of light if genes are discovered that are sensitive to say, infrared or ultraviolet spectra. #neuroscience

    This reminds me of a study I heard on NPR about studying in Community College. They said, the kids who studied more did better, while the kids who had to work while going to school did worse. Weird. I mean, if you focus solely on school, you did better than if you had a job?

    How much did this study cost, about a million dollars? #neuroscience

    Why do they think they have to move on to studying sports teams? I know I've read at least 2 reports of the same thing happening to sports fans when their teams lose, from different countries.

    So, DUH... they're repeating old studies with bad methodology. I guess this is what passes for intellectual at Duke? #neuroscience

    I tried to resist for a long time, but have now accepted that as soon as the second round of cortical implants are available I'll be first in line.

    Why second, you might ask? Well, first of all, they're gonna be fucking expensive. An iPhone cost roughly the GNP of Egypt when it first came out; imagine what a shunt in your skull that will stream the internet directly to your brain will be worth.

    Secondly, I don't need to be dealing with first-gen bugs in my wetware. Algae cultures pourin' out of your eye sockets and what-not. #neuroscience

    Yay, you used my tip. That article was pretty amazing, but I doubt I'll ever get to see many real life applications of that tech during my lifetime.

    "Of course, this kind of cyborg technology is not exactly around the corner."

    Not true. Just yesterday I saw a recent piece on a two-way artificial hand and it doesn't use optogenetics. Watch the video. #neuroscience

    I like the comment from the link.

    "Too bad the testosterone increase doesn't transfer to the socialist politicians so they will stand and defend the USA."

    Seriously, dude. There's a whole 1 socialist politician in the federal government. His name is Bernie Sanders.

    PS Why did the Barr voters' testosterone levels drop? That makes as much sense as if my levels dropped when McKinney didn't win.

    "OH NO my third party candidate didn't win an election in a two-party system!" #neuroscience

    @artiofab: I guess the testosterone drop is not necessarily related to surprise, just disappointment. #neuroscience

    "This is a pretty powerful result," said Duke neuroscientist Kevin LaBar. "Voters are physiologically affected by having their candidate win or lose an election."

    Aw rilly?

    In other news, women cry more often and longer than men.

    (I really read that was news today)

    Surprising huh?

    We need reinforcements, let's call captain obvious.

    Yeah, I read the whole article and it IS bad science, because if you want to prove that the event E lowers trestosterone in group A, you have to compare the group A when E happens, with the group A when E doesn't happen, leaving all the other circumstances unchanged.

    The conclusion seems pretty obvious to me, but the methodology is flawed. They should have repeated this with at least two groups of republicans and two groups of democrats, measuring with two differents meethods, one in each group, because maybe chewing gum raises Republicans' testosterone and loweed it in Democrats. And repeated it at least twice, having another day (same week day, diferent week), and measure the difference to a regular week, because maybe Republicans lose more testosterone after their sunday dinner than the Democrats do.

    As I say, it seems obvious that disappointment lowers one's testosterone, but this experiment doesn't prove it. #neuroscience

    One of the researchers working on this gave a lecture at my school. It was both interesting and unnerving (no pun intended) watching a mouse begin to run in circles at the flip of a switch. #neuroscience

    A post yesterday was about an artificial arm that could both receive orders from the brain and send feedback back to it... So presumably there are other ways of doing this?

    [io9.com]

    This is still so awesome, though. Of course, changing the genetic structure of neurons seems a bit scary, too... I wonder if there'd be a way to build a sort of "adapter," which would be built separately from your body, and would include (artificially-grown) genetically augmented neurons that would respond to light signals from electronic devices, and could be "grown into" your nervous system, without changing neurons you already have? #neuroscience

    @ParryLost: Nah, that arm was hooked up to the nerves in his arm, not directly to his brain at all. There is a big difference in the difficulties involved, though both are awesome. #neuroscience
