...surely a well-rehearsed demonstration by now, Bremner goes on to address the case against Knox, point by point. The prosecution, she says, is most likely relying on a knife found at the house of Knox's then boyfriend and fellow accused Rafaelle Sollecito. That knife has Knox's DNA on the handle and what some forensic scientists say is Kercher's DNA on the tip. But Bremner dismisses the idea that it is the knife that killed Kercher: "They never found the murder weapon." Bremner claims that a bloody print on the bed linens conveys the shape...
...whether the DNA on the tip belongs to Kercher, experts disagree. Patrizia Stefanoni, a police forensics expert who testified in the pretrial hearing in May, suggested that it was Kercher's DNA on the tip of the knife - and that the way the genetic material was positioned indicated the knife had probably been used to puncture the skin. But other experts who have analyzed the DNA evidence for the defense suggest that poor sample quality and possible contamination undermine the accuracy of these results...
Researchers used DNA data and self-reported lifestyle surveys from nearly 2,500 participants in the National Longitudinal Study of Adolescent Health, the largest and most comprehensive survey of health-related behavior among adolescents between 7th and 12th grade, which started in 1994. Slightly more than half of the study's male participants had low-level activity on the MAO-A gene, and about 3% of the total pool reported having joined a named gang in the past year.

...Maryland Mouse DNA Decoded In a breakthrough 10 years in the making, an international team of scientists has finished sequencing just the second complete mammalian genome: that of the mouse. The findings will help researchers better distinguish between mouse and human DNA--which are about 75% alike--and promote more targeted experiments on human illness...
...missing cases, says it's possible that the number could be much larger - possibly as high as 500. Pyongyang further inflamed the Japanese in 2004 when it returned a jar of ashes that they claimed were the remains of young Yokota. The Japanese government asked Teikyo University to conduct DNA tests to verify that they were Yokota's remains. They were not. (See pictures of Kim Jong...
