DNA Demands Chimps Be Grouped in the Human Genus

Proposed changes in the primate order are stirring up evolutionary debate. Humans and chimpanzees should be grouped in the same genus, Homo, according to WSU researchers in a May 19 article (#2172) published in the Proceedings of the National Academy of Sciences. Although WSU’s Morris Goodman, PhD, has already proven with non-coding DNA sequences that chimpanzees are closest in kinship to humans rather than to gorillas, evolutionary traditionalists say chimps and humans are functionally markedly different and therefore belong on different branches of the family tree.

Cancer drug ‘smart bomb’ on horizon

Today, even the best cancer treatments kill about as many healthy cells as they do cancer cells. But a St. Louis researcher has begun to lay the conceptual and experimental groundwork for a new strategy for chemotherapy — one that turns existing drugs into medicinal “smart bombs.” The approach is essentially a sophisticated drug releasing system, one that can recognize and use cancerous DNA sequences as triggering mechanisms for the drugs that fight them.
