...academy has pushed back the age for the first of three hepatitis-B shots, which also contain thimerosal, from birth to two to six months in children whose mothers test negative for the disease...
...found mostly in the forebrain and hippocampus (where explicit, long-term memories are formed). The researchers spliced the gene that creates NR2B into the DNA of ordinary mouse embryos to create the strain they called Doogie. Then they ran the mice through a series of standardized tests--sort of a rodent sat. In one, the mice were given a paw shock while in a box; after a few rounds, they showed signs of fear from just being in the box, having learned that a shock was likely to follow. They learned in similar fashion to be afraid when a bell...
...year-old daughter Elizabeth, whom he was raising as a single father. His co-defendant, Ron Williamson, landed on death row and came within days of being executed. Years later, Williamson's conviction was reversed on a technicality. Before retrying him, prosecutors decided to do a DNA test of semen and hair found at the crime scene and compare them with Williamson's. Fritz's lawyers asked them to test Fritz too. Result? The DNA excluded both men and implicated someone else who had never been charged with the crime. Last April, after 12 years behind bars, Fritz and Williamson...
Such stories have become shockingly familiar: a convicted criminal, wasting away in jail with little hope of ever proving his innocence, is set free when a DNA test reveals he couldn't have committed the crime. Vincent Jenkins, who had served 17 years in prison for the rape of a Buffalo, N.Y., woman, was released just last week after DNA evidence showed he was not the culprit. He became the 65th inmate to have a conviction overturned thanks to DNA evidence, including eight released from death row. These numbers are testimony to the fallibility of our criminal-justice system...
When those letters do get opened, students and staff screen the cases using the Innocence Project's criteria: When the inmate was tried, was identity the key issue? (If he admitted he pulled the trigger but claimed it was self-defense, there's not a lot a DNA test can do to help.) Was biological evidence taken at some point? In rape cases semen is generally recovered, and in murder cases there is often hair or skin evidence. But some samples come from less obvious sources: in the World Trade Center bombing case, DNA was recovered from saliva...
