Kirsty Spalding never expected to start her biology postdoc standing in a Swedish slaughterhouse, dressed in white overalls and rubber boots amidst blood and gore and stink, while smashing the teeth out of decapitated horses' heads with a hammer. But that's exactly where the young Australian scientist found herself, every second Tuesday in 2002 for two months at the beginning of her postdoc in the l

It was 1994, and Scott Simonet of Amgen's molecular genetics department in Thousand Oaks, Calif., was looking at some strange X-rays. He had engineered five transgenic mouse lines to overexpress a mysterious secreted protein. The mice looked and behaved normally, but that ordinariness was only skin-deep. "On the X-rays, it was pretty obvious that the long bones had higher bone mineral density," says

In 2004, strange things were happening when people living in the Southern United States received Erbitux, an anticancer drug. After Erbitux was approved, the first three patients that oncologist Bert O'Neil treated at the University of North Carolina, Chapel Hill, had severe anaphylactic reactions. "One fell out of their chair," passing out as blood pressure plummeted. "It alarmed us."
