Filmmaker Working On Eye-Socket Camera 114

Posted by Soulskill from the take-two-they're-small dept.
An anonymous reader writes "Wired has a story about Rob Spence, a Canadian filmmaker who plans to have a mini camera installed in his prosthetic eye. 'A camera module will have to be connected to a transmitter inside the prosthetic eye that can broadcast the captured video footage. To boost the signal, he says he can wear another transmitter on his belt. A receiver attached to a hard drive in a backpack could capture that information and then send it to another device that uploads everything to a web site in real time. ... Even though his project is still in its early stages, Spence says many people have already told him they wouldn't be comfortable being filmed. "People are more scared of a center-left documentary maker with an eye than the 400 ways they are filmed every day at the school, the subway, the mall," he says. He hopes he will help get people thinking about privacy, how surveillance cameras and the footage they record are being used and accessed.'" Spence runs a blog for the 'Eyeborg Project,' as he calls it, and has recently posted a video about the progress they're making.

Scientists Solve Century-Old Optics Mystery 265

evan_arrrr! writes "From the article: Since the early 20th century physicists have known that light carries momentum, but the way this momentum changes as light passes through different media is much less clear. Two rival theories of the time predicted precisely the opposite effect for light incident on a dielectric: one suggesting it pushes the surface in the direction light is traveling; the other suggesting it drags the surface backwards towards the source of light. After 100 years of conflicting experimental results, a team of experimentalists from China believe they have finally found a resolution."

Birth of the Moon: a Runaway Nuclear Reaction? 355

Posted by CmdrTaco from the that's-not-no-moon dept.
An anonymous reader writes "How the Moon arose has long stumped scientists. Now Dutch geophysicists argue that it was created not by a massive collision 4.5 billion years ago, but by a runaway nuclear reaction deep inside the young Earth."

Stretching Before Exercising Weakens Muscles 339

Posted by kdawson from the everything-you-know-is-wrong dept.
Khemisty writes "Back in grade school you were probably taught the importance of warm-up exercises, and it's likely you've continued with pretty much the same routine ever since. Science, however, has moved on. Researchers now believe that some of the more entrenched elements of many athletes' warm-up regimens are not only a waste of time but are actually bad for you. The old presumption that holding a stretch for 20 to 30 seconds — known as static stretching — primes muscles for a workout is dead wrong. It actually weakens them. In a recent study conducted at the University of Nevada, athletes generated less force from their leg muscles after static stretching than they did after not stretching at all. Other studies have found that this stretching decreases muscle strength by as much as 30 percent. Also, stretching one leg's muscles can reduce strength in the other leg as well, probably because the central nervous system rebels against the movements."

X-Rays Emitted From Ordinary Scotch Tape 190

Posted by timothy from the unusual-circumstances dept.
Maximum Prophet writes "When I was in High School, I built an X-Ray machine that (probably) didn't produce any X-Rays. I used an old vacuum tube and high voltage. Little did I know that simple triboluminescence would have enough energy to do useful work." The catch: you'll need to peel your tape in a vacuum, and have the x-ray film at the ready.

Number of ET Civilizations In Our Galaxy Is 37,964 544

Posted by CmdrTaco from the give-or-take-infinity dept.
KentuckyFC writes "The famous Drake equation calculates the number of advanced civilizations in our galaxy right now. But the result is hugely sensitive to the assumptions you make about factors such as the number of habitable planets that orbit a host star, how many of these actually develop life and what fraction of these go on to become intelligent etc. Disagreements about these figures leads to estimates for the number of advanced civilizations ranging from 10^-5 to 10^6. Now an astronomer in Scotland has worked out how to make the calculations more precise so that different theories about the origin of planets, life and civilizations can be compared. His calculations say that the rare-life hypothesis predicts only 361 advanced civilizations in the Milky Way now. However, the so-called tortoise and hare hypothesis predicts 31,573 and the theory of panspermia says that there ought to be 37,964 extraterrestrial civilizations more advanced than our own in the Milky Way."
