"I made a calculation error and used a lot more than I should have. And my cells died," Schaefer said. A colleague overheard her complaining. "The co-author on my paper said,' Did I hear you say you killed some cancer?' I said 'Oh', and took a closer look." They ran several tests and found the compound killed "pretty much every epithelial tumor cell lines we have seen."

Amero was substituting for a middle-school English class and asked the regular teacher permission to use the computer to e-mail her husband. The teacher granted her permission, and asked her not to log him out of the computer. Amero, the self-professed techno-noob, then left the room to use the restroom, and upon her return says that she found several students gathered around the machine looking at a web site. A series of unfortunate events occurred from this point on, resulting in a slew of pornographic pop-ups appearing on the screen. The onslaught continued despite Amero's attempts to close the windows.

When the students told their parents what had happened, they told the administration, who vowed that Julie would never work in the classroom again. But they went further. The 40-year-old substitute teacher was arrested, indicted, tried and here is the kicker on January 5, 2007, she was convicted of four counts of risk of injury to a minor, or impairing the morals of a child (Conn. Gen. Stat. 53-21). Indeed, she was originally charged with exposing 10 children in the seventh grade class to the materials on the internet, but six of the charges were dropped.

"Our data shows that marital conflict is not a major culprit," said epidemiologist Nick Martin, from the Queensland Institute of Medical Research. "Rows have often been blamed for ratbag behaviour but we've got no evidence to suggest that they are the problem." Researchers, including several from the US, studied 1,045 pairs of twins and their children to see whether the link between parental fighting and kids' conduct problems was genetic or environmental. They found that children of an identical twin had the same levels of behavioural problems regardless of whether it was their parent or their parent's identical sibling that had marital rows.
