if (n == null) The Scientist - From Basic Research to Cancer Drug: The Story of Cisplatin The Scientist 13[14]:11, Jul. 05, 1999 News From Basic Research to Cancer Drug: The Story of Cisplatin By Ricki Lewis Clinical Trial Results for Treating Cervical Cancer The April 15, 1999 issue of The New England Journal of Medicine (NEJM) brought great satisfaction to Barnett Rosenberg, a retired Michigan State University biophysicist who founded the Barros Resear

Genome of Thermotoga maritima Reveals Lateral Gene Transfer

"Thermotoga was selected because it is near the base of the Woesean tree," says Craig Venter, TIGR chief scientific officer and president of nearby Celera Genomics Corp. The Woesean tree is the three-pronged depiction of the domains of life named for Carl Woese, the University of Illinois microbiologist who discovered the Archaea in 1977.2 The Archaea are microorganisms that lack nuclei as do traditional Eubacteria, yet have transcriptional and translational machinery and other characteristics

Image provided by Genzyme Transgenics Corporation CLONING GOATS In contrast to cloning's popular image as a brave new way to mass-produce monsters, biologists have described cloning as a tool to ease other biotechnologies. Researchers from Louisiana State University in Baton Rouge, Genzyme Transgenic Corp. in Framingham, Mass., and Tufts University School of Medicine in North Grafton, Mass., have shown how cloning can dramatically increase the efficiency of creating goats that secrete valuable

NAS Elects 60 New Members, 15 Foreign Associates
Ricki Lewis | | 6 min read
Editor's Note: The National Academy of Sciences has elected 60 new members and 15 foreign associates from 10 countries in recognition of their distinguished and continuing achievements in original research. In this article, The Scientist presents photographs of most of the new members and comments from some of them. A full directory of NAS members can be found online at www.nas.edu/nas. When in 1977 the genes of eukaryotes were found to be riddled with nonprotein-encoding stretches of bases,

Prions' Changeability: Nuclear magnetic resonance shows more pieces of the puzzle
Ricki Lewis | | 7 min read
Prions have been a tough sell. Against a backdrop of the "DNA to RNA to protein" credo, the idea that the same amino acid sequence could exist in multiple forms, both normal and deranged, seemed like heresy. But since Stanley Prusiner, a professor of neurology, virology, and biochemistry at the University of California, San Francisco (UCSF), named the agent that causes the transmissible spongiform encephalopathies (TSEs) "proteinaceous infectious particles" in 1982,1 evidence has been steadily

Human Mesenchymal Stem Cells Differentiate in the Lab
Ricki Lewis | | 5 min read
While prominent scientists plead with legislators to reconsider their conservative stance on funding human embryonic stem (ES) cell research, a six-year-old company in Baltimore is quietly making the matter moot. In a just-released tour-de-force research report, it is no longer quite so quiet.1 Researchers at Osiris Therapeutics and the Johns Hopkins University School of Medicine coaxed human mesenchymal stem cells (hMSCs) from adults' bone marrow to develop into cartilage, fat, and bone cells

Peanuts may be losing their bite PEANUT ALLERGY VACCINE Peanuts are more than just an annoyance on airplanes--for a few dozen people each year, they cause deadly anaphylactic shock. The only protection is knowledge of one's allergy and avoidance of the offending food. But most peanut-associated allergic deaths occur from peanut extracts added to prepared foods--additives that sometimes remain unlisted on labels. A peanut allergy vaccine could prevent such deaths. Kam Leong, a professor of biom

Mixing Religion and Health: Is it Good Science?
As the millennium approaches, spirituality is playing a more prominent role in medical practice. Many Americans believe that religious activity can promote health, and physicians report an increasing number of patients requesting at least discussion of religion in their treatment. In response, about 30 medical schools now offer courses in religion and spirituality.1 Support comes from other sectors too. "The Senate recently appropriated $50 million to set up five major centers to study mind-bo

Genetics Society Offers Thoughts for Future
Ricki Lewis | | 5 min read
Eugenics comes in many guises, from the fetal hatcheries of Aldous Huxley's 1931 vision of a brave new world, to films such as Gattaca, where parents pick and choose their future offspring's inherited traits. In the real world, eugenics is associated with the horrors of Nazi Germany, and more subtly with certain medical tests widely used in many nations today. The blurring of the lines between eugenics and genetic research has prompted the American Society of Human Genetics (ASHG) to release a

Biotech Blooms at the University of Georgia
Ricki Lewis | | 7 min read
Clifton A. Baile The two-decades-old biotech industry remains largely concentrated in a few epicenters. Now Georgia is about to stake its claim on the biotech map, thanks to an unusual synergy of state government, industry, and academia. Since 1990, the Georgia Research Alliance (GRA) has purchased equipment, erected new facilities, and supported eminent scholars, building on existing infrastructure and scientific talent at its six major research universities. A series of losses in the 1980s

SEEING THE RETINA Borrowing a technique that clarifies images from spy satellites, researchers from the University of Rochester have imaged the distribution of cone cells in the human retina (A. Roorda, D.R. Williams, Nature, 397:520-2, Feb. 11, 1999). The three types of cone cells have photopigments that absorb predominantly short (S), middle (M), or long (L) wavelengths, corresponding to blue/violet, green, and red. Color vision works much like a color television--the brain integrates the i

Broader Ph.D. Training Can Benefit Science and Society
Ricki Lewis | | 6 min read
The problem and the solution seem obvious: Scientists are training many more graduate students than are needed for available academic positions, and science illiteracy in the United States is rampant. Newly trained scientists working outside academia might ease the glut, plus perhaps pass their enthusiasm and knowledge to the public. Statistics tell the story. According to the National Research Council (NRC), in 1985, 3,791 Ph.D.s were granted in life sciences, and the job market held 20,377 t
