Harold Varmus is president of the Memorial Sloan-Kettering Cancer Center since 2000, and took the position after serving for more than six years as director of the NIH. The 1989 Nobel Prize winner is also a cofounder of the Public Library of Science and a member of the Science Initiative Group (SIG). On page 24, he makes the case for Global Science Corps, a SIG program that aims to place well-trained scientists and engineers in the research centers of developing countries to collab

Talk of systems biology has a way of drifting, quite rapidly, into the abstract. I'm reminded of the preamble to Georges Perec's complex but engaging novel, Life, A User's Manual."The art of jigsaw puzzles seems of little substance, easily exhausted, wholly dealt with by a basic introduction to Gestalt: The perceived object... is not a sum of elements to be distinguished from each other and analyzed discreetly, but a pattern, that is to say a form, a structure... knowl

A new type of cancer cell growthRe: cancer stem cells.1,2 Recently we have reported a novel type of cell division involved in the origin and growth of cancers.3,4 Termed neosis, this type of cell division occurs only in senescent polyploid giant cells and never in normal diploid cells. Up to 10% of tumor cells both in vitro and in vivo are polyploid, and so far there is no explanation of their role in cancer. These resemble senescent cells, which are thought to be part of the tumor

Now imagine keeping 7,000 of those animals fed.That's the task of the staff at Kruger National Park, a 2-million hectare reserve that stretches 350 kilometers along South Africa's border with Mozambique. The elephant's appetite has an enormous impact on the surrounding envi

On scanning her nametag, one of my colleagues notices an interesting affiliation: Philip Morris. Intrigued, my colleague asks the senior research scientist about her work, which she says involves "harm reduction."With 16,000 people in attendance, BIO

As SARS emerged in 2003, attention quickly turned to airplanes, the most likely source of international spread. At the time, the US Centers for Disease Control and Prevention (CDC) received passenger manifests, usually in hard copy, to notify people who had shared a flight with someone later diagnosed with the infection.In the Internet age, that procedure was hardly ideal. "The paper management of data was problematic," says the CDC's Christie Reed, mainly because of the di

HIV'S ANNIVERSARY >> June 5 marks 25 years since the disease now known as AIDS was first reported (see p. 36), but it was only 51 years ago that researchers first dissected a virus into its constituent parts and put it back together. On June 10, 1955, Heinz L. Fraenkel-Conrat and Robley Williams at the Virus Laboratory of the University of California at Berkeley reported the deconstruction and reconstitution of the tobacco mosaic virus, demonstrating that RNA serves as its genetic materi
