+ - In Texas, SpyRecon is Wire Tapping

Submitted by underpar

His spying resulted in a four-year prison sentence.""

+ - Genetically engineered mouse is not scared of cats

Submitted by

Gary writes "A team from the University of Tokyo have genetically engineered a mouse that does not fear cats. By tweaking genes to disable certain functions of the olfactory bulb (the area of the brain that receives information about smells directly from olfactory receptors in the nose) the researchers were able to create a "fearless" mouse that does not try to flee when it smells cats, foxes and other predators."
It's funny.  Laugh.

+ - knitting with DNA in a microscope...->

Joost van Mameren writes "By grabbing the ends of DNA with laser beams, one can make DNA do very unusual things. It is even possible to put a loop in a DNA molecule and slide it along a second DNA molecule, even though DNA and proteins are much too small to see with a microscope! Researchers of VU University, Amsterdam, use so-called "optical tweezers" to grab plastic beads with a diameter of only a thousandth of a millimeter, that are visible under a microscope. The beads are caught in the focal point of a focused laser-beam. By sticking the ends of two DNA molecule to such beads, they can bend, twist and stretch the DNA anyway they like. The website provides a little video demonstrating their DNA gymnastics."
