Conductive cosmetics to control mobile devices

Computer scientist Katia Vega has developed conductive eye shadow and false eyelashes that can be used to control wearable computers. For example, an extended blink could trigger your phone's camera. "We use voluntary movements to amplify intentions – using our body as a new input device," Vega, a researcher at Rio de Janeiro's Pontifical Catholic University, told New Scientist.

Women in science tees



Jeremy sez, "To celebrate Ada Lovelace day, celebrating women in science and technology (Tuesday, Oct 15th this year) I've put together a collection of t-shirts featuring women in science and technology. Since I know that despite their contributions many of these women are not household names I've also added a brief writeup of each woman's best known accomplishments when you mouse over each design."

Gonzo essay on the limits of chip design

The term "gonzo journalism" gets thrown around pretty loosely, generally referring to stuff that's kind of shouty or over-the-top, but really gonzo stuff is completely, totally bananas. Case in point is James Mickens's The Slow Winter [PDF], a wonderfully lunatic account of the limitations of chip-design that will almost certainly delight you as much as it did me.

The first integrated circuit

NOVA's Tim De Chant posted this awesome photo of the Kilby Solid Circuit, the first working example of a miniaturized electric circuit that combined all the necessary structures onto a single chip. Back in 2000, when he won the Nobel Prize for this achievement, inventor Jack Kilby gave a really nice talk about the history of electronics and the context that lead to his creation. It's definitely worth a read.

How The Cleveland Press broke the story of Los Alamos a year-and-a-half before Hiroshima

The Manhattan Project was a secret, but it wasn't as secret a secret as you've been lead to believe, writes Rebecca Rosen at The Atlantic. Not only was the construction of an atomic weapon a topic of Washington gossip, but the entire "secret city in the desert" thing got blown open in 1944 when a columnist for a Midwestern newspaper ran across Los Alamos while on vacation. In light of our current debates about state secrets and security, it's probably less interesting that columnist Jack Raper found Los Alamos, and more interesting that he, and his paper, chose to buck the self-enforced system of silence that characterized World War II media.

How to parent, according to the archives of Popular Science

Popular Science has a great (and occasionally horrifying) slideshow of gadgets it once suggested were essential for enlightened, tech-minded parents. A lot of the inventions merely look way sketchy. For instance, the infant-sized "sleeping porch" that is actually a screened box bolted into an apartment window frame is probably mounted well enough that it's not going to kill anybody. It's just that, from the vantage point of a 100 years later, it seems a little disturbing to stick your baby into something that looks like a large AC window unit.

Other suggestions, though, are legitimately concerning. Above, you can see an image of a nurse "branding" a newborn by essentially sunburning its parent's initials onto its flesh with a UV lamp. In 1938, somebody thought this would be a good way to ensure that nobody left the hospital with the wrong baby.

How one chemist does her research, even though her lab makes her sick

LuAnne McNulty is an organic chemist. A few years ago, she developed severe asthma that's triggered by ... well ... organic chemistry. Not too long ago, that biological reaction would have put her out of a job. Today, she's able to conduct research (if not do it herself) and advise younger scientists with the help of really simple tech solutions. Maggie 5

The Uncanny Valley might not actually exist

The Uncanny Valley is that point where something designed to look human gets too close to success, and ends up accidentally reminding us of the many, many ways that it also looks totally alien. The result: A one-way ticket to Creepoutsville.

Or, anyway, that's the hypothesis. See, despite the fact that we've long treated it as a given, the Uncanny Valley isn't a proven concept. In fact, writes Rose Eveleth at The BBC, the original 1970 paper that described the Uncanny Valley wasn't really based on research at all. It was more of an essay. An essay that nobody much questioned for 30 years. Since 2000, there's been some actual research on the subject, and the results are very mixed. Some studies can find evidence of the Uncanny Valley. In others, though, it appears to not exist at all.

Squirrels hell-bent on destruction of American electric infrastructure

If you enjoy the irony in the fact that the great East Coast blackout of 2003 was largely caused by a few untrimmed trees, then you're going to love Jon Mooallem's account of how America's squirrels are wreaking havoc on America's electricity system.

Using a Google news alert, he's cataloged 50 squirrel-caused power outages in 24 states — and that's just since Memorial Day. These aren't small outages either. Several of them have cut power to thousands of people at a time. Back in 1994, a squirrel took out the Nasdaq. These are kamikaze raids and they've led to an interesting phenomenon — technology developed specifically to protect our infrastructure from furry, tree-hopping rodents.

Regulating a new technology

E-cigarettes are different enough from cigarettes that it's hard for regulators to figure out how to monitor their safety and use. There's nicotine, but no tobacco. There's heating, but not combustion. Theoretically, they should be safer to use than cigarettes, but nobody really knows for sure. This piece at InsideScience is an interesting look at how we manage new technologies that don't quite fit into any previously defined regulatory boxes ... and why we'd want to regulate them, to begin with.

Ancient nanotechnology

Linotype machines are awesome

Last night, my husband and I went to the Minnesota State Fair and stumbled upon a demonstration of a linotype machine, a semi-automated, mechanical printing system that was used by newspapers and magazines (and basically everything else) from the end of the 19th century through the 1970s. It's a completely mesmerizing piece of equipment. An operator types out a line of text and the machine responds by collecting molds that match each letter and fitting them together. Then, it fills the mold with molten metal and dumps out the freshly minted block, ready for the printer ... before automatically re-racking all the letter molds so they're ready for the next line of text.

Today's schizophrenics hallucinate different things than those of your grandparents' time

Thanks to that whole "mental" part, mental illnesses are often heavily influenced by the cultures and societies in which people live. Case in point: The way people with schizophrenia interpret their own hallucinations has changed over the course of the 20th century, keeping pace with changes in technology. Where people once believed that demons were speaking to them, they came to think of those voices as emanating from secret phonographs. Today, people with schizophrenia are likely to imagine hidden cameras taping them for a reality show. The paranoid delusions are always there, but the context changes. Maggie 16

How to: Shop for a computer in 1953

Ptak Science Books reprints a helpful article from the journal Computers and Automation, meant to help early computer shoppers make sure they're wisely spending their hundreds of thousands of dollars (in 1953 dollars, that is). You don't want to end up with a gigantic, room-sized piece of machinery that doesn't meet your needs or, worse, is a lemon. Maggie 4

Elon Musk's hyperloop can't escape the high cost of infrastructure development

Elon Musk wants to build a pneumatic tube transportation system capable of whisking people from San Francisco to Los Angeles in 30 minutes. (Xeni told you about this back in July.)

Technologically speaking, it's a perfectly possible thing to do, writes Tim Fernholtz at Quartz. The problem is the high cost of infrastructure development, something have everybody (whether they want to built a train, a highway, or a futuristic hyperloop) tends to underestimate. That's particularly a problem given the fact that whole idea behind Musk's hyperloop is that it could be a cheaper replacement for an expensive high-speed rail line already under development.
