In 1955, a puckish, 30-year-old Weishman resigned as lecturer in theoretical physics at the University of Manchester to become science correspondent of the Manchester Guardian. Unwittingly, the energetically eclectic John Maddox thus took his first step toward the editorial chair of Nature, which he has occupied with distinction on two occasions—between 1966 and 1973, and from 1980 until the present. A robust defender of what he calls “the scientific enterprise,” Maddox has

The Scientist has asked a group of expert. to periodically comment upon recent articles that they have found noteworthy. Their selectIons, presented here in every issue, are neither endorsements of content nor the result of systematic searching. Rather they are personal choices of articles they believe the scientific community as a whole may also find i.nteresting. Reprints of any articles cited here may be ordered through The Genuine Article, 8501 Market St., Philadelphia, Pa. 19004. BY SOK

Until recently, most artificial-intelligence researchers accepted the view that thinking consists of the manipulation of discrete symbols, such as the written or spoken language. With this understanding, they achieved a degree of progress, notably in machine understanding and generation of natural-language communication, in symbolic mathematics programs, and in the automatic proving of theorems and assertions by machines. Groups at MIT, Carnegie-Meilon, and Stanford dramatically extended theore

E.O. WiLson, editor, NationalAcademy Press; Washington, D.C.; 496 pages, $19.50 (paperback); $32.50 (hardback) People have far fewer genes than do salamanders or many flowering plants, says Wilson as he piles up statistics to demon- strate the abundance of genetic information stored in living things. This richness—and its fragility—are examined from different angles by this volume’s 55 contributors. PATTERNING IN SEED PLANT SPECIES Jonathan D. Sauer, University of Californi

Congress is in a tizzy; science leaders are worried legislation could do harm to the innocent WASHINGTON--Fraud in science has become a cause célébre among Washington politicians. For a two-week period this spring, it seemed that everywhere one looked there were concerned and aggrieved congressmen. And as the politicians aired the dirty linen of science in public and fulminated over measures they claimed needed to be taken to assure the public that science would be pursued in a spot

Scientists, beware! The West German hacker who invaded scores of U.S. military computer systems last year could easily strike again. Scientists at Lawrence Berkeley Laboratory who finally tracked the electronic wizard down have been studying his M.O. Their conclusion: His tactics were often ridiculously simple. Many of the systems he entered used account names and passwords so obvious as to be worthless. And many current systems continue to use similar passwords. The best defense? Difficult p

Between 1977 and 1986, the United States produced more than 42% of all articles on mapping and sequencing the human genome that appeared in 3,200 of the world’s leading scientific journals, the Congressional Office of Technology Assessment (OTA) reported in a study issued in late April. “The United States is the clear leader in basic research, publishing more articles on mapping and sequencing than European or Asian nations,” it concluded. The next largest contributor over t

Faculty salaries seem to be losing steam, according to the latest annual survey from the American Association of University Professors. In 1986-87, the average salary levels for all disciplines rose 5.9%, but in 1987-88 the increase was only 4.9%. Adjusted for inflation, the increase was less than 1%. Private independent institutions gave bigger raises than did public or church-related universities. Salaries differed according to region. The highest average salary ($43,590) came from the Pacif

NSF has elevated its programs in instrumentation and related areas to the level of a division in the Directorate of Biological, Behavioral, and Social Sciences. The new Division of Instrumentation and Resources includes such programs as instrumentation and instrument development, field stations, database software development, history and philosophy of science, ethics and value studies, and special projects such as science and technology centers. John Wooley is acting division director. The fir

There is a growing market out there for part-time and/or temporary work in the sciences. Employers have long seen the advantages—savings in overhead and benefits plus greater flexibility in many activities—but now the practice of research is changing, moving toward almost interchangeable scientists performing routine, clearly divided tasks. At the same time, based on our work in the professional relations office of the American Chemical Society I see an increasing interest in this

The ramshackle state of some of the nation’s science labs has prompted the Kresge Foundation in Troy, Mich., to step beyond its regular pattern of giving and add a special program for upgrading scientific equipment. The foundation, with assets of more than $1 billion, traditionally restricts its funding to construction and building-renovation projects. Now, says Kresge program officer Gene Moss, the foundation expects to give away between $10 million and $20 million for scientific equip
