GRIM OUTLOOK: Postdocs need to realize that the odds of getting tenure-track academic jobs are poor, says CSPT's Catherine Gaddy. The once-predictable world of scientific postdoctoral research appears to be entering a period of transformation. Increasingly left in an employment limbo by shrinking tenure-track faculty positions at universities, science postdocs around the United States are beginning to organize and clamor for change. But for many, a nonacademic career seems unavoidable. "The c

Computer consultants warn that the cost of adjusting programs will skyrocket if researchers wait until after their systems crash Jan. 1, 2000, is coming. While self-proclaimed prophets are out pounding pulpits to warn against impending cosmic doom, computer programmers, engineers, and information specialists are wringing their hands over a far more mundane issue-how computers will handle the switch from the year 1999 to the year 2000. Many fear that some instruments and applications won't hand

The Kyoto Accord to reduce "greenhouse" gas emissions faces a hazy future in the United States. A host of unresolved political and scientific issues swirls around the tentative plan to curb global warming-including the degree to which greenhouse gases actually affect the environment. Kyoto sets the stage for science, politics, and public opinion to interact on the largest possible scale, and, some would say, at the highest possible stakes. Science's pivotal role is to take on a formidable chall

Meta-analysis, which uses systematic methods to search, combine, and evaluate research literature, has been praised for making the review article more scientific and objective. But studies showing that journals are much more likely to publish the results of positive over negative clinical trials have led some to question the validity and objectivity of meta-analyses. Many in the medical community are concerned that this publication bias may skew the results of meta-analyses, which increasingly

In three short years it will be Jan. 1, 2001, the first day of the 21st century and a new era. The United States will be expecting the inaugural message of a new president and the world will enter the Third Millennium. As the Second Millennium ends, we ought to think about what kind of a world we should and could realistically hope for. We certainly need a world with fewer than the often-predicted 12 billion people who may be present before the end of the 21st century. Unfortunately, in our mad

The market for Ph.D.'s in science and engineering is a matter of perennial concern, both to employers and to those who earn these degrees and expect to make a career in the field of their choice. Predicting supply and demand of the scientific work force, however, is a tricky business fraught with uncertainties. In 1989, widely reported statistics from the National Science Foundation caused NSF to project a shortage of Ph.D. scientists by the middle to the end of this decade. Events turned out d

I found Ricki Lewis's article in the Nov. 10, 1997, issue of The Scientist ("Instructors Reconsider Dissection's Role in Biology Classes," page 13) of great interest. Having attained a baccalaureate in biology in the 1970s and graduate degrees in biomedical sciences during the '80s and '90s, and taught college-level biology courses (all of which required extensive use of laboratory animal models), I have been an interested observer of the transformation that has occurred in the philosophy of th

Wherever did Paul Smaglik get the idea that the boost in the National Institutes of Health's Office of Alternative Medicine (OAM) budget to $20 million was "unexpected" (P. Smaglik, "Office of Alternative Medicine Gets Unexpected Boost," The Scientist, Nov. 10, 1997, page 7)? In my opinion it was coldly calculated. No one, not even Sen. Tom Harkin (D-Iowa), would have expected Congress to give OAM institute status and a budget of $200 million. But by demanding just that and forcing the Congress

While the list of genome projects grows, research focus is shifting from structure to function. So even as automated DNA sequencers crank out bases and powerful software overlaps pieces of genomes (contigs) to establish gene orders, investigators are searching and comparing those sequences among species, an approach called comparative genomics.

Committee service is one of those time-consuming chores that are part of virtually every academic scientist's life. While many researchers regard committee work as distasteful drudgery, others relish their service. Experienced scientists say that service on internal and external committees, when performed with a strategic eye, can help advance one's career. They also note that there are ways to make serving less onerous and to make committee deliberations more efficient. Of course, not every

CLARIFICATION Author: Date: January 5, 1998 A photo caption accompanying a Notebook item headlined "Genetic Down Syndrome Test" (The Scientist, Nov. 24 1997, page 31) contained incorrect information. The left photo shows a single pink signal, indicating one copy of chromosome Y, which is considered normal. A double copy of that chromosome would indicate Jacob syndrome, not Down syndrome, as the caption indicated. Down syndrome is characterized by three (trisomy 21) copies of ch

Milli-Q Ultrapure Water Systems From Millipore The latest generation of Milli-Q systems from Millipore Corporation (Bedford, Mass.) has been subjected to some unique innovations designed to enhance user-friendliness and provide consistent performance. Primed For Polishing: The Milli-Q System From Millipore. The Milli-Q system is considered a "polishing" system, designed to further purify pretreated water to ultrapure levels. Although these systems are relatively small (12 x 17 x 20 inches), ide

Faster, cheaper, cleaner. All of these words describe Genomyx's latest addition to its line of products for differential display analysis of gene expression. The new Fluorescent Differential Display Adaptor Kit (fluoroDD Kit) provides fluorescently labeled primers that can be used with Genomyx's HIEROGLYPHTM mRNA Profile Kits to allow for a rapid and nontoxic alternative to radioactive labeling of differential display products.

There were precursory polymerases, such as that from E. coli, that lost their enzymatic activities at elevated temperatures. This shortfall made thermal cycling a time-consuming chore, with the necessity of adding new polymerase after each cycle. Then came the thermostable polymerases such as Taq DNA polymerase, which was isolated from the thermophilic, aerobic bacterium Thermus aquat
