Biopharmaceutical researchers fear how pending federal legislation outlawing the cloning of human cells will restrict their abilities to find cures for major degenerative diseases.1,2 Some also see lawmakers impinging on established nonhuman cloning techniques essential for the discovery of new drugs and therapies. The source of all this worry? The US House of Representatives passed July 31 by a wide margin a bill (H.R. 2505) sponsored by Reps. David Weldon (R-Fla.) and Bart Stupak (D-Mich.) th

For Genes Author: Holly Ahern For a geneticist, pinpointing a mutation in a human gene that might be responsible for an inherited disease can be likened to the proverbial search for a needle in a haystack. While mo-lecular biologists sift through the 3 billion base pairs in the human genome in search of disease-causing genes, other scientists choose to approach the problem from the perspective of the mouse, a model system for mammal research. Because mice and humans are members of the same gr
