Scientific American reports on military research to "juice up" soldiers' brains using amphetamine-alternatives like Provigil and Ampakine CX717. The aim, of course, is to find the next generation "go pill
" that fighters can pop to stay awake longer without impairing their cognitive abilities. The article also discusses transcranial magnetic stimulation (TMS), a method to stimulate specific regions of neurons to possibly alleviate depression or, of interest to the military, improve reaction time. (More on TMS in this
Popular Science article I wrote several years ago.) For me though, the most interesting bit in the SciAm article is the brief discussion of the "fear gene." From the article:
A distinguished team of U.S. researchers reported in 2005 that a gene called stathmin, which is expressed in the amygdala (the seat of emotion), is associated with both innate and learned fear. The researchers bred mice without the gene and put them in aversive situations, such as giving them a mild shock at a certain point in their cage. Normal mice exhibited traditional fear behavior by freezing in place, but the altered mice froze less often. And when both types of mice were put in an open field environment--an innately threatening situation--the mice without stathmin spent more time in the center of the field and explored more than the control mice.
Do individuals who have lesser stathmin expression exhibit less fear? It is unlikely that there is a one-to-one correspondence, because humans are far more psychologically complex than mice, capable of modifying their genetically programmed behavior. Yet it is not difficult to imagine that a military official who overestimates the significance of genetic information will someday propose screening Special Forces candidates, or even raw recruits, for the "fear gene." Indeed, a few years ago the Burlington Northern Santa Fe Railway Company had to pay $2.2 million to employees who had been secretly tested for a gene associated with carpal tunnel syndrome, even though the scientists who developed the testing technique said it could not work for that purpose. The company was trying to see if the workers' medical claims were attributable to their jobs or their genes.
If DNA testing for a fear gene is both scientifically and ethically dicey, what about setting out to create people who lack that characteristic? Would breeding humans without stathmin or other genes associated with fear reactions engender more courageous fighters? Would parents sign on for such meddling if they harbored ambitions for a child capable of a glorious military career or just didn't want to give birth to a "sissy"?
Neglected public payphones in New York City are being turned into “GuyFi” stations: a place where one can rub one out for the sake of “stress relief.” Annalee Newitz reports on the wank booths from a company named “Hot Octopus”… The company reported that at least 100 men used the booth on its opening day […]
You’d be forgiven for thinking the videocassette format long-dead, but it turns out that Betamax is still around. Sony is finally going to withdraw tapes from sale, bringing a 40-year story to an end. The last recorders were sold in 2002. ベータビデオカセットおよびマイクロMVカセットテープ出荷終了のお知らせ [Sony; via The Verge]
A leaked Comcast memo discloses that the company’s consumer data caps have nothing to do with network congestion, contrary to its public claims. The internet service provider has often complained (such as when lobbying against net neutrality) that it must impose limits on service to prevent network congestion. The argument suggests that these measures are […]
Remember back to the time when people thought java was just a hip way to talk about coffee? Or you vaguely remembered from geography class that it’s an island in the South Pacific? We’ve come a long way since then and now that we’ve rocket blasted into the tech future, you’re going to need to […]
Plastic is so 2013. You don’t want to buy something only to throw it away or lose it and barely care. You like nice things and want to hang onto them. The Plazmatic lighter here is a high quality, high tech alternative to the typical cheap, plastic lighter you get at the old gas station. […]
Real engineers build things. Super cool engineers build things with their hands and fingers, like our engineering forefathers did. No idea where to even begin to do that? This step by step Arduino course is now 92% off and is going to get you up and running, from zero to hero, in no time. So […]
