Not all awards are created equal. That's why the International Congress of Distinguished Awards (ICDA), a Philadelphia-based organization, published the Official Roster of Distinguished Awards, a directory of 116 prizes that the ICDA considered the best of their kind. It gave those awards its seal of approval based on uniqueness to a particular field, amount of cash prize, and professionalism of administration. (See www.icda.org.) Keeping up with awards is difficult, because most of the approxim

Much of what scientists know about the origins of cancer and the role of tumor suppressors can be traced back 28 years to the elegant theory of cancer researcher Alfred G. Knudson. Widely thought to be one of the most significant theories in modern biology, Knudson's "two-hit" hypothesis was recognized Nov. 19 at the John Scott Awards in Philadelphia, along with the revolutionary research of Benoit Mandelbrot, the discoverer of the powerful mathematical laws governing fractal geometry and self-s

One way to encourage women to stay in science and move up to prominent positions is to reward them for their accomplishments. A small percentage of women are being nominated for and winning prizes at the highest levels, such as Nobel or Lasker awards. However, women may be overlooked at earlier stages of their careers, and that has a negative effect on their scientific futures. Brigid Hogan, professor of cell biology at Vanderbilt University Medical Center and one of four women on the Lask

Caitilyn Allen The dearth of women in science and engineering has spawned programs on college campuses to redress the balance and encourage women to stay in science. According to the National Science Foundation,1 a little more than 22 percent of the scientists and engineers in the United States in 1995 (the date of the most recent figures) were women. Though women make up about half of the social scientists, they are noticeably underrepresented among the "hard sciences." The NSF reports that 20

For years, evolution's critics picked on supposed gaps in the historical record--missing links between different forms or species in biologists' evolutionary lineages. Evolutionary leaps, say from dinosaurs to birds, are inconceivable without intermediates, so the reasoning went. Finding key fossils is no easy matter, but creationists interpreted the absence of evidence as evidence of absence--no links, no evolution, only supernatural design. Paleontologists were patient, though. They predicted

I enjoyed reading the article "Fears or Facts? A Viewpoint on GM Crops."1 I second Peter Raven's remarks on genetically modified (GM) plants. The Europeans have obviously been misled by their media; hence, their irrational fear of GM food sources. Is it the Galileo syndrome all over again? Are we not manipulating genes when breeders make artificial crosses using gametes from a male and female plant to improve their varieties? Are we not already consuming hybrid corn, hybrid rice, and high-yieldi

European consumers are protesting the sale of U.S. food products because of concerns about genetically altered crops. In Russia, weapons-grade uranium is being stored in inadequately protected facilities, increasing the risk that a terrorist organization or rogue nation might steal the material to build nuclear weapons. A new disease has made its way from Africa to New York and is threatening to spread along the East Coast. Most of us would agree that dealing effectively with these thorny inter

"Our results suggest that a genetic enhancement of mental and cognitive attributes such as intelligence and memory in mammals is feasible." This sentence, from a scientific paper published in the Sept. 2 issue of the international journal Nature by the laboratory of Joe Tsien of Princeton University,1 ignited a firestorm of publicity. The study, using genetically modified mice (I'll get to the actual scientific findings in a moment), was reported as news by major print and broadcast outlets. T

For decades, that's been a message on bumper stickers and a cry of environmentalists. In recent months, the number of reports raising serious concerns about the health of the oceans and their inhabitants has only increased. Human dependence on the oceans has been well documented; therefore, the benefits of cleaning up these waters globally and protecting all that dwell therein seem obvious.

Hydra HTS Workstation In 1992, Robbins Scientific released the Hydra-96, an innovative device that relieved researchers from repetitive, manual liquid dispensing. Further development led to the Hydra-384, capable of dispensing reagents in a 384-well format. Now, Robbins Scientific offers its latest technology, the Hydra HTS Workstation, for automated handling of source and target plates. One component of the Hydra HTS Workstation is the Hydra-PP (automated plate positioner), which consists of a

Traditionally, cytokines have been measured by radioimmunoassays (RIA) and enzyme-linked immunosorbent assays (ELISA). Unfortunately, these techniques are limited by their detection range and an inability to simultaneously measure multiple analytes. By using immunofluorescence assays (IFA) and extremely sensitive multiparameter flow cytometers, BioErgonomics' MultiFlow-IFA Multiple Cytokine Immunoassay kits overcome both of these limitations. BioErgonomics' Multiflow-IFA Multiple Cytokine Detect

Have you ever used one of those low-temperature sample storage blocks that you remove temporarily from the freezer? Ever feel uncomfortable about how well that block maintains its temperature while on the benchtop, despite what the manufacturer claims? Have you silently cursed the puddle that forms under it as that block's frosty coating melts? Torrey Pines Scientific Inc. of Solana Beach, Calif., has redefined laboratory sample temperature control with the recent introduction of its ECHOtherm M

If the resumes of the Science Talent Search (STS) finalists over the past 60 years are any indicator, winning a scientific prize early in one's career certainly can have a positive effect. Over a six-decade time span, STS--formerly called the Westinghouse Awards and now called the Intel Science Talent Search--has given out scholarships to more than 2,200 young researchers. Two have gone on to win Lasker Awards; nine have received MacArthur Fellowships; three the National Medal of Science; two th
