A robot trying to find you will use thermal imaging based on the roughly 91-degree temperature of human skin, so smearing yourself in cool mud will confuse them. If being chased by an unmanned robot vehicle, flee to a rustic, unmapped area with lots of obstacles. If your robot "smart" house -- one wired with video surveillance and computer gear -- tries to trap you, chop your way out with an ax and don't take your cell phone, because the house will track you with it.(Via Cosmic Log.)

"Defend yourself against the coming robot rebellion". Although it's mostly a humor book (written by a real roboticist), some of the tips are real:
"Technology that provides live translation of speech from one language to another has been revealed by scientists from the US and Europe."
"Was It Something I Ate?: What to do if you think a restaurant meal has made you sick." (Via Linkfilter.)

Bone marrow transplants can cause false positive matches with criminal DNA testing. For example, there was
...an Alaska case in which a man was linked to an attack, based on DNA obtained with blood tests, but had been in jail at the time.More details here. (Via SciTech Daily.)
It transpired the sex attack had been carried out by his brother, who had donated bone marrow to his sibling in a transplant some years earlier.
I would love to take a stroll on this proposed Grand Canyon Skywalk. (Scheduled to open Jan 1 2006.)

Can physicists create sound waves that travel faster than light? More information here. Of course, this all has to do with the group velocity of the waves, so no faster-than-light information or energy transfer is involved. (Via Cosmic Log.)
"A new clinical trial in the United States allows couples to pick the sex of their unborn children in an effort to determine the social effects."
Dolphins don't need 6 degrees of separation: A recent study of the dolphin community off the coast of Scotland shows that "it takes an average of just 3.9 steps to link any two dolphins by the shortest possible route through mutual friends."
Optical Illusion of the Day: "Mr. Angry and Mrs. Calm". The image shows two faces. Up close, the face on the left looks angry while the face on the right looks calm. But if you stand about 10 feet away, they switch places! Here's the technical paper (PDF format) on how it works. (Via Clicked.)

Mathematical analysis of wobbly tables.
Do you always get the wobbly table at restaurants and cafes? Don't despair. A physicist has proved that, within reasonable limits, it is always possible to rotate the table to a position where all four legs stand solidly on the ground.Here's the full proof for the mathematically inclined (PDF format).
Andre Martin was moved to study the problem because he was fed up with the wobbly tables at CERN, the European particle physics laboratory in Geneva, Switzerland, where he works on abstruse problems in high-energy physics.
Scientists have invented a scanner that can look inside concrete. It expected to be useful both for checking for hairline cracks, as well as looking for murder victims.
"White House Orders Satirical Paper 'The Onion' to Stop Using Presidential Seal". Apparently this is real. I'm no lawyer, but I would think that The Onion's use of the seal would fall clearly within the bounds of parody/satire. More information at this NY Times article. (Via MeFi.)
Invention of the day: "Naughty" digital camera lens. According to the article,
A camera lens that allows one to see through clothes and other hard surfaces has been introduced by a US Company.Of course, there are some demonstration images. (Via Madville.)
The lens that could well result in it being banned because of its perve potential is called the "Infrared See-Through Filter PF". The PF is a special optical device that helps to visually penetrate an object's surface in order to view whatever lies below. The PF makes it possible for you to see images that are normally invisible to the human eye. It sounds like science-fiction but it isn't, this new product has been developed using newly developed advanced optical technology.

Malcolm Gladwell has written an excellent essay on secret quirks of Ivy League admissions policies. Some of the Harvard and Yale anti-Jewish policies in the mid-20th century were especially eye-opening. The section on admissions standards for student-athletes was also quite interesting.

Invention of the day: A special tap designed to pour the perfect beer at twice the speed of regular taps. (Via SciTechDaily.)
iRobot (the makers of the Roomba robotic vacuum cleaner) are developing an anti-sniper robot. According to the article,
When REDOWL's microphones detect a gunshot, the device calculates the source of the sound, swivels the camera, illuminates the target with either visible or infrared light, and uses a laser to calculate the range...The system is not configured to fire back automatically -- this still requires positive human intervention. (Via /.)
"You'll actually see the sniper before the smoke disappears from the shot," said Joe Dyer, iRobot's executive vice president and general manager.
