Enzon Inc. gains ground in a growing industry with its innovative approach for enhancing the efficacy and durability of medicine Abraham Abuchowski was a Rutgers University biochemistry graduate student in the 1970s when his adviser set him to work on an inert polymer called polyethylene glycol (PEG). Abe Abuchowski, 42, runs his company the way he teaches karate classes. The cofounder and CEO of Enzon Inc. in South Plainfield, N.J., Abuchowski got hooked on the martial art while an undergra

Editors fear that a recent redefinition of `protected speech' could force them to stifle controversy in order to avoid lawsuits The freedom of scientists to candidly criticize their colleagues' theories in professional journals could be sharply curtailed by a Supreme Court ruling on libel handed down this past summer. Journal editors currently defending themselves in court against charges that their publications have been a party to a malicious attack fear that the high court decision could ha

Suppliers of laboratory chemicals and plastics are already beginning to feel the pinch from rising crude oil prices in the wake of the worldwide embargo of Iraqi oil. But it's not clear when-or if-scientists will have to pay more for those products. Officials at some companies, like J.T. Baker Chemical Inc. of Phillipsburg, N.J., one of the country's largest suppliers of laboratory solvents and other chemicals, say they plan to pass the cost increases onto their distributors, who could try to

Iraqi invasion interrupts many international projects; Kuwaiti researchers fear warfare gas devasted their life's work As the world watches with alarm the unfolding crisis in the Middle East, the international science community is assessing losses resulting from the August 2 Iraqi invasion of Kuwait. The blow to Kuwaiti science is disastrous, and the damage of the attack extends beyond the borders of the small Persian Gulf country. Future international collaborations in the Middle East may be

Florida State's victory over MIT in gaining a new lab makes it clear that NSF is inclined to reward fresh vision and determination The National Science Foundation wants universities to know that it takes more than technical excellence and a good reputation to win a large grant. What's required are hard work, a long-range vision, a commitment to training the next generation of scientists, and a knack for obtaining outside funding to augment whatever the federal government can provide. What NSF

Inspired by the mandate to find alternatives, researchers link up to create new technologies and substitute chemicals WASHINGTON--Leslie Guth always thought her research was too technical for casual conversations. Not anymore. Now when Guth, a materials scientist for AT&T Bell Laboratories in Murray Hill, N.J., mentions that she's looking for new ways to finish electronic circuit boards without using chlorofluoro-carbons, people are eager to hear more about her battle against what many env

WASHINGTON-The Bush administration last month shaped the course of the two most important agencies for academic science within the federal bureaucracy by identifying its candidates for the directorships of the National Institutes of Health and the National Science Foundation. Its choices also suggest that presidential science adviser Allan Bromley has gained the upper hand in such personnel decisions over a range of competing interests within the White House. The selection of cardiologist Berna

But when Johns Hopkins University's Applied Physics Lab employees decided to create plush surroundings for a breeding group of nonmigrating Maryland mallards, they didn't count on the problem of homeless ducks. Over the past few years seven domestic geese and six white ducks have been abandoned at the

Why is innumeracy so widespread even among otherwise educated people? The reasons, to be a little simplistic, are poor education, psychological blocks, and romantic misconceptions about the nature of mathematics. My own case was the exception that proves the rule. The earliest memory I have of wanting to be a mathematician was at age 10, when I calculated that a certain relief pitcher for the then Milwaukee Braves had an earned run average (ERA) of 135. (For baseball fans: He allowed five runs

I was quite taken by the juxtaposition in "Ominous Statistics Foretell Drastic Shortage Of Scientists" and "But The Figures Can Exaggerate Our Anxiety" [The Scientist, June 25, 1990, page 11]. I would like to suggest a way to allay this disastrous shortage before it occurs. Why don't we try funding the Ph.D.'s we are producing now? One of my key concerns about getting on the Ph.D. track has been the wages, both now and in the future. Before I came to graduate school in molecular biology, I was

The article "New Gene Technologies Could Reap Rich Floral Harvest" [The Scientist, Aug. 20, 1990, page 8] tells us that "A discipline that flourished for 30 years after plant hormones were first discovered in the 1920s, plant biology languished for a generation (my emphasis) until the late 1970s, when molecular techniques were first applied to plant systems." To me, this statement reflects either na9ve ignorance of recent history or a type of "molecular arrogance" based on the premise that the

While attending two conferences in the U.S., I read your interview with presidential science adviser Allan Bromley [The Scientist, July 23, 1990, page 1]. I wonder if Bromley makes a distinction between teaching and research at universities the way German politicians do. Research at German universities is "teaching- research" and an important part of study. However, universities should teach mainly creativity and less book knowledge. Knowledge could be learned from books, too, but creativity a

At this time of year, guessing who will win the Nobel Prize is a popular parlor game for scientists. The fact is, of course, no one except members of the Nobel awards committees can possibly predict the fields or discoveries that will be selected, much less the actual winners. Like the weather, however, fields and individual winners can be intelligently forecast. And one of the strongest indicators of Nobel-class science is citation frequency. That's the major criterion--along with whether a re

Molecular biology has come a long way in the nearly 40 years since James Watson and Francis Crick published their classic paper on the three-dimensional structure of DNA (Nature, 171:737-738, 1953). Since then, the intimate relationship between nucleic acids and proteins has not only been deciphered, but also harnessed and manipulated to fuel a whole new industry. Armed with sophisticated equipment, today's molecular biologists can easily extract, purify, and sequence DNA, RNA, and proteins, a
