likely. "Liquid crystal display technolo­gy is a prime example of a hybrid mo­lecular-semiconductor technology that has achieved widespread success/' he says.

One of the problems that has to be solved with protein memory cubes is the provision of an environment for the pro­tein that will give it stability over de­cades rather than a few years. "Right now, our memories will store informa­tion for five years plus or minus a year without any trouble," says Birge. "It's going to take a lot of additional work not only using chemistry but also using mo­lecular biology to make something that can store data on the order of 20 years."

Birge considers protein memory cubes to be more environmentally friendly than semiconductors, howev­er. "There are several steps in making a semiconductor device, such as cleans­ing and etching, that involve a major amount of pollution," observes Birge. "The preparation and isolation of the protein is environmentally safe, and you can even eat the protein. It is nutri­tious, but not delicious."

New journal forgoes traditional peer review Rustum Roy doesn't think much of peer review as it is traditionally prac­ticed. For years, he has complained that it slows the dissemination of research findings and is biased against truly in­novative results. He favors peer review of past performance instead.

Almost three years ago, Roy, a promi­nent materials scientist at Pennsylvania State University, caused a stir by an­nouncing a research advance in dia­mond synthesis at a press conference be­fore any journal had even had a chance to review the work (C&EN, Oct. 26, 1992, page 5).

And now he's fired another salvo in his campaign against traditional peer review by preparing to launch a mate­rials science journal that will rapidly publish "new, unexpected, and innova­tive" results without the delays caused by reviewers.

Other materials researchers contacted by C&EN do not regard the peer review system as an outdated relic of the past— as Roy does—and they are not enthused by a new journal that throws traditional peer review out the window.

Roy's new journal, Innovations in Materials Research (IMR), will examine the author's past publications track record "instead of nitpicking on the de­tails of [the] submitted manuscript," Roy explains in the journal's publicity re­lease.

the journal will publish readers' com­ments on published papers. All such comments will be published using the title of the original paper, followed by an appropriate addendum, such as Dis­cussion, Correction, or Reply to Discus­sion. This, Roy believes, will ensure that computerized searches will lead to a complete record including corrections and comments. He hopes that this fea­ture "will restore some of the personal vitality to the literature."

Roy, who is editor-in-chief of JMR, has assembled a "very distinguished" board of 20 editors from around the world to handle manuscripts. The journal will be published by World Scientific Publish­ing in Singapore. He expects the first is­sue of IMR to roll off the presses in July, followed by two or three more issues in 1995. The plan is to print six issues in 1996, and to go to monthly publication after that. By January 1996, Roy hopes the journal will be able to publish a pa­per within two months.

Of course, the publication schedule depends on what kind of reception the journal gets. "Frankly, I don't know whether we will be swamped or starved" in the beginning, Roy says. Submissions are just beginning to trickle in. Asked about the quality of the pa­pers, Roy mentions one paper that is "first rate" and another that is on the borderline between "really innovative" and "weird."

That could be a hint of what is to come. Timothy M. Swager, a materials chemist at the University of Pennsylvania, pre­dicts that the new journal "will not be used by creditable scientists. It will most likely be the Natwnal Enquirer of the sci­entific literature and will largely be used for amusement rather than dissemina­tion of scientific information."

This opinion is echoed by chemistry professor Charles M. Lieber of Harvard University: "Cold fusion is a perfect ex­ample of a 'truly innovative and unex­pected' result that would benefit from such a journal. The peer review system is not perfect [but] I have found that most scientists offer honest and constructive comments in these reviews, and I believe that such criticism ultimately leads to better scientific publications."

Chemistry professor David M. Walba of the University of Colorado, Boulder, admits having "decidedly mixed feel­ings" about IMR. "I am sympathetic to the basic idea of a fast-turnaround vehi­cle for hot new results," he says. On the

other hand, if good materials work is not appearing in existing refereed journals, he adds, it may be up to the materials community to do a better job of referee-ing for those journals.

Other researchers contacted by C&EN also didn't see any particular need for this new journal. And they questioned whether someone with truly innovative results would prefer to publish them in a new journal that doesn't have an estab­lished reputation.

Roy has heard all this before: "They said exactly the same things when we started the first materials journal—the Materials Research Bulletin—in 1966 and when a group of us started the Materials Research Society in 1973. They both changed the culture of materials science."

IMR is "an experiment," Roy contin­ues. "Maybe it won't work." But if it does work, he hopes the idea "will catch on and spread" throughout the publica­tions world. "That's my hope—that it'll save the [materials] community a lot of time and effort."

Individual subscription rates for JMR start at $85. In the U.S., orders (and re­quests for a complimentary issue) may be placed by calling (800) 227-7562.

'Evolved' ribozyme boosts view of RNA Researchers in Boston and Santa Cruz, Calif., have discovered that RNA has the hidden ability to catalyze a critical bio­logical reaction, bolstering the theory that RNA was the primary agent of life before DNA and proteins took over.

RNA, or ribonucleic acid, a single-stranded nucleic acid chain, is best known for its role as DNA's messenger. But RNA molecules can also behave like enzymes, catalyzing reactions with them­selves and other pieces of RNA. These specialized snippets are called "ribo-zymes," a term coined by their discoverer, Thomas R. Cech, a chemistry professor at the University of Colorado, Boulder. Cech received the 1989 Nobel Prize in Chemis­try for his work on ribozymes.

It is RNA's ability to assume both genetic and enzymatic duties that has led some researchers to propose that life began with RNA. In this scenario, early forms of RNA would have per­formed the jobs of both DNA and pro­teins, until these two separate molecu-
