Founder of medical genetics dies

By | July 24, 2008

Victor McKusick, who founded the field of medical genetics at Johns Hopkins University, died on Tuesday, July 22, at his home outside Baltimore. He was 86 years old. "Victor's vision is reflected in his early recognition of the inherent value to medicine of mapping the human genome," said Aravinda Chakravarti, director of the McKusick-Nathans Institute in a 2002 linkurl:statement.; "His contributions to the practice of genetics in medicin


Rethinking aging

By | July 24, 2008

Aging may not be caused by the accumulation of cellular damage, as a linkurl:prominent theory; suggests. Instead, the process may result from the deterioration of crucial developmental pathways, according to a study published tomorrow in Cell. "What we found is, I think, a different way to think about aging," linkurl:Stuart Kim; of Stanford University, main author of the study, told The Scientist. Kim and his coll


Biotech bailing on stem cells?

By | July 23, 2008

The announcement last week of Advanced Cell Technology's imminent closure is evidence that embryonic stem cell technology may be linkurl:too nascent; for fruitful biotech innovation, according to some industry analysts. For the past 10 years Advanced Cell Technology (ACT) has been a spotlight company for linkurl:endeavors; in embryonic stem cell research and cloning. But in a Securities and Exchange
