A six-week "debate" on women in science that began Sept. 9 on the Nature Web site is the latest illustration of how media technology is helping to turn the long struggle for female parity with male colleagues into an internationally shared experience. Helen C. Davies "I can't help contrasting this with what has gone before," comments Helen C. Davies, president of the Association for Women in Science and a microbiology professor at the University of Pennsylvania Medical Center. Recalling effor

As disease resistance to antibiotics and other drugs continues to build, even new methods of discovery such as combinatorial chemistry may not be able to meet the ever-increasing need for more efficient and more effective compounds. According to a core group of researchers, however, an untapped reservoir of powerful new medicines is in the oceans. In fact, so rich is life in the oceans that some seafaring scientists go so far as to say the greatest bounty in the medicine chest of the new millen

The chemoprevention field could be characterized as being in a double-blind double bind. One side of the field emphasizes taking a "whole food" approach to using food to prevent cancer. That approach entails having scientists closely monitor everything a necessarily small group of subjects eats over a necessarily short period of time. Such studies pick apart the complexities of diet and its possible roles in keeping cancer at bay. But the small numbers and short time frame put any conclusions o

Numerous studies have found that female scientists publish at slower rates than male scientists. In a classic statement of the problem, Jonathan Cole and Harriet Zuckerman characterize this gender gap in publication rates as "the productivity puzzle."

The banded Gila monster's saliva may help provide a new treatment for type II diabetes mellitus. NEW TREATMENT FOR DIABETES II? A chemical in the saliva of the Gila monster Heloderma suspectum that helps digest gigantic meals may provide a new treatment for type II diabetes mellitus. The Gila monster is one of only two venomous lizards and hails from the Phoenix, Ariz., area, coincidentally the home of the Pima Indians, who have the world's highest incidence of type II diabetes." John Eng, a

Since the mid-1980s, variations on the DNA fingerprinting theme have left their marks on diverse fields. By comparing distinctive DNA sequences, aberrations, or numbers of repeats among individuals, investigators have matched suspects to crime scenes and parents to offspring; assembled body parts in the aftermath of disasters; identified kidnap victims, Thomas Jefferson's son, and the remains of Tsar Nicholas' family, who were executed in 1918; and exonerated 64 prisoners, including nine on dea

Celera Genomics announced Sept. 9 that the Rockville, Md., company had sequenced the 1.8 billion base pairs that make up the Drosophila melanogaster genome. Now comes the tricky part--putting them together to form an accurate, contiguous fruit fly genome. "The sequence data is good," Paul Gilman, a Celera vice president, claims. "The question is, 'How good is our assembly?'" That's a question that critics of the company's "whole genome shotgun" sequencing approach--blasting the entire genome in

Understanding the genetic structure of ecosystems is important in saving biodiversity. That's especially vital as humans fragment vast natural areas into isolated patches, cutting off avenues for outcrossing. Unfortunately, scientists' understanding of breeding systems and gene flow may be even more fragmented than the ecosystems. Botanists are hard at work remedying the situation. Using genetic markers, they analyze plant paternity and infer how far pollen travels on gentle breezes or the bac

On Aug. 30 Harold Varmus, National Institutes of Health director, invited all members of the scientific publishing world to attend his version of a peer-review free-for-all. Several weeks later, it remains to be seen who will show up. The gala in question is PubMed Central, an Internet research repository first proposed by Varmus May 5 under the name E-biomed. The renamed repository will contain two kinds of research after its January 2000 addition to the popular PubMed Web site: non-peer-revi

A scene from the Missouri Botanical Garden The saying "if you want something done, give it to a busy person" fits Peter Raven like a glove. Director of the Missouri Botanical Garden since 1971, home secretary of the National Academy of Sciences, and author of textbooks in biology and botany, Raven hosted about 5,000 scientists from more than 100 countries as president of the XVI International Botanical Congress in St. Louis August 1-7. With Harvard University's Edward O. Wilson, Raven is biodi

It's a simple but haunting question: Can microgravity influence gene expression? Yes, according to a recent study of human cells conducted aboard NASA's space shuttle. In fact, the results are so promising that the investigators believe their continuing research could lead to better toxicology tests, key elements of tissue engineering, and new treatments for various diseases--while broadening the scope of scientific experimentation.

When Paul R. Sanberg became a neuroscientist, he focused on Huntington's disease. When he realized that Parkinson's disease was related, he expanded his horizons. And when his father suffered a stroke about five years ago, he shifted his priorities. Some of the things he has learned since may help treat all three diseases, as well as a number of other neurodegenerative disorders. Following his father's stroke, Sanberg recalls months of trips between Tampa, where he worked as a researcher for t
