In the summer of 2007, a team of Stanford graduate students dropped a mouse into a plastic basin. The mouse sniffed the floor curiously. It didn’t seem to care that a fiber-optic cable was threaded through its skull. Nor did it seem to mind that the right half of its motor cortex had been reprogrammed.
One of the students flipped a switch and intense blue light shone through the cable into the mouse’s brain, illuminating it with an eerie glow. Instantly, the mouse began running in counterclockwise circles as though hell-bent on winning a murine Olympics.
Then the light went off, and the mouse stopped. Sniffed. Stood up on its hind legs and looked directly at the students as if to ask, “Why the hell did I just do that?” And the students whooped and cheered like this was the most important thing they’d ever seen.
Because it was the most important thing they’d ever seen. They’d shown that a beam of light could control brain activity with great precision. The mouse didn’t lose its memory, have a seizure, or die. It ran in a circle. Specifically, a counterclockwise circle…
Though touted as completely safe because the level of radiation is so low, travelers have been nervous about the devices — and not just because it shows off a nice outline of their privates to the people manning the machines — but because they remain scared of the health problems they might propose.
Looks like a little healthy paranoia might have been a good thing. While the conventional wisdom has held that so-called “terahertz radiation,” upon which backscatter x-ray machines are based, is harmless because it doesn’t carry enough energy to do cellular or genetic damage, new research suggests that may be completely wrong.
Specifically, researchers have found that terahertz radiation may interfere directly with DNA. Although the force generated is small, the waves have been found to “unzip double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication.”

Much has been made of the 32MB of Goldman Sachs’ proprietary algorithmic trading code (“trading secrets”) allegedly stolen by Sergey Aleynikov, now portrayed in the financial media as the new Julius Rosenberg, Aldrich Ames, Robert Hanssen and John Walker all rolled into one. That may prove to be true; but while it makes for a great news story at this point in time, it highlights the new significance of high frequency trading—which is built on this technology—in the marketplace.
Security researchers found that poor shielding on some keyboard cables means useful data can be leaked about each character typed.
By analysing the information leaking onto power circuits, the researchers could see what a target was typing.
