Courtesy of MonsantoRice, the most widely consumed staple food grain, is harvested on about 10 percent of the world's arable land. Researchers are cranking out genomes faster than many scientists can digest them. Just 10 days after publication of Drosophila's sequence (see page 10), Monsanto Co. announced it will soon release a rough draft of the rice genome containing 400 million bases of DNA. Rice is the world's most important food crop. The International Rice Research Institute in the Phi

Bacteria are winning, and infectious disease doctors are worried. Disease-causing microbes are increasingly able to defeat the best antimicrobial drugs available. No "superbug" has yet emerged, resistant to all antibiotics and therefore untreatable. But that day may not be too far off. "There's increasing panic among infectious disease specialists,'' admits Jonathan Blum, a clinician and researcher at Harvard Medical School. Particularly worrisome to those specialists is a strain k

When the federal Office for Protection from Research Risks (OPRR) ordered Virginia Commonwealth University (VCU) to halt all human subject research in January, it was another punitive measure in that agency's 14-month-long series of actions that sent a clear message to the research community: Researchers spending federal tax dollars should diligently consider ethics in their work. This particular case, however, especially troubled genetics researchers. It involved the father of a research

In December of 1999, after digesting three months of public comment on a preliminary draft, the National Institutes of Health released the final version of a policy entitled "Principles and Guidelines for Sharing of Biomedical Research Resources."1 The policy advises NIH grantees on, among other things, the appropriate way to disseminate unique research tools--everything from cell lines to reagents to animal models to laboratory equipment to computer software--that arise out of grant funding. It

Women in Cancer Research Women in Cancer Research (WICR) will dissolve as an independent organization and become a council in the American Association for Cancer Research (AACR). In essence WICR is going back to its roots. According to Mary Jean Sawey, immediate past president of WICR and research associate professor of radiation oncology at Temple University Medical School, several years ago many female scientists felt they needed a vehicle to promote advancement of women in cancer-related bio

The word astronomical aptly describes current price estimates for a manned jaunt to Mars: $40,000 per pound. "That's an expensive can of Coke" for astronauts making the trip, says Brian Sauser of NASA's New Jersey Specialized Center of Research and Training (NSCORT). So NSCORT's mission is not to figure out how to ship food, air, and energy to Mars, but to create and re-create it up there. Speaking at a recent meeting of Science Writers in New York, the New York science writer's associati

Editor's Note: This is the second of two articles on the difficulties of proving that a virus contributes to a disease. The first article, on mouse mammary tumor virus and human breast cancer, appeared in the April 17 issue of The Scientist.1 Donald R. Carrigan and Konstance K. Knox Someone once said that if you want to ruin your reputation, go into MS [multiple sclerosis] research, quips Jacqueline E. Friedman, a senior research associate at Rockefeller University. But Friedman, who deals wit

Cancer Research Topics Researchers discussed new approaches and promising drug targets at the American Association for Cancer Research meeting in San Francisco last month, including protein delivery and metastasis. Protein Delivery: Steven Dowdy, a Howard Hughes Medical Institute investigator at Washington University, reported on a way to get large proteins into cells in vivo. Typically only small molecules can cross the lipid membrane surrounding the cell. Dowdy and his colleagues circ

Plant Cell Culture Reagents Photo by Harry F. Holloway, CCP and Jeff McAdams. Courtesy of Carolina Biological Supply Co.Tobacco callus serves as the starting material for cell culture. The culture of plant cells began as a method to simplify studies of plant biology, but applications of this technology have become big business. Many researchers are genetically engineering plants to be hardier or more nutritious. Others want to harness the plants' ability to produce beneficial compounds at will,

Scientific Information Proliferates Are you keeping up? Keeping up with the literature can be hard for scientists, but keeping up with developments in electronic publishing in the life sciences is even harder. The plethora of new names, Web sites, and services has grown dramatically in recent months. Here are a few highlights: * PubMed Central is the barrier-free National Institutes of Health repository for peer-reviewed primary research reports in the life sciences. It began accepting journal
