Leading academic journals are distorting the scientific process and represent a “tyranny” that must be broken, according to a Nobel prize winner who has declared a boycott on the publications.

Randy Schekman, a US biologist who won the Nobel prize in physiology or medicine this year and receives his prize in Stockholm on Tuesday, said his lab would no longer send research papers to the top-tier journals, Nature, Cell and Science.

Schekman said pressure to publish in “luxury” journals encouraged researchers to cut corners and pursue trendy fields of science instead of doing more important work. The problem was exacerbated, he said, by editors who were not active scientists but professionals who favoured studies that were likely to make a splash.

The prestige of appearing in the major journals has led the Chinese Academy of Sciences to pay successful authors the equivalent of $30,000 (£18,000). Some researchers made half of their income through such “bribes”, Schekman said in an interview.

Writing in the Guardian, Schekman raises serious concerns over the journals’ practices and calls on others in the scientific community to take action.

“I have published in the big brands, including papers that won me a Nobel prize. But no longer,” he writes. “Just as Wall Street needs to break the hold of bonus culture, so science must break the tyranny of the luxury journals.”

Schekman is the editor of eLife, an online journal set up by the Wellcome Trust. Articles submitted to the journal – a competitor to Nature, Cell and Science – are discussed by reviewers who are working scientists and accepted if all agree. The papers are free for anyone to read.

Schekman criticises Nature, Cell and Science for artificially restricting the number of papers they accept, a policy he says stokes demand “like fashion designers who create limited-edition handbags.” He also attacks a widespread metric called an “impact factor”, used by many top-tier journals in their marketing.

A journal’s impact factor is a measure of how often its papers are cited, and is used as a proxy for quality. But Schekman said it was “toxic influence” on science that “introduced a distortion”. He writes: “A paper can become highly cited because it is good science – or because it is eye-catching, provocative, or wrong.”

Daniel Sirkis, a postdoc in Schekman’s lab, said many scientists wasted a lot of time trying to get their work into Cell, Science and Nature. “It’s true I could have a harder time getting my foot in the door of certain elite institutions without papers in these journals during my postdoc, but I don’t think I’d want to do science at a place that had this as one of their most important criteria for hiring anyway,” he told the Guardian.

Sebastian Springer, a biochemist at Jacobs University in Bremen, who worked with Schekman at the University of California, Berkeley, said he agreed there were major problems in scientific publishing, but no better model yet existed. “The system is not meritocratic. You don’t necessarily see the best papers published in those journals. The editors are not professional scientists, they are journalists which isn’t necessarily the greatest problem, but they emphasise novelty over solid work,” he said.

Springer said it was not enough for individual scientists to take a stand. Scientists are hired and awarded grants and fellowships on the basis of which journals they publish in. “The hiring committees all around the world need to acknowledge this issue,” he said.

Philip Campbell, editor-in-chief at Nature, said the journal had worked with the scientific community for more than 140 years and the support it had from authors and reviewers was validation that it served their needs.

“We select research for publication in Nature on the basis of scientific significance. That in turn may lead to citation impact and media coverage, but Nature editors aren’t driven by those considerations, and couldn’t predict them even if they wished to do so,” he said.

“The research community tends towards an over-reliance in assessing research by the journal in which it appears, or the impact factor of that journal. In a survey Nature Publishing Group conducted this year of over 20,000 scientists, the three most important factors in choosing a journal to submit to were: the reputation of the journal; the relevance of the journal content to their discipline; and the journal’s impact factor. My colleagues and I have expressed concerns about over-reliance on impact factors many times over the years, both in the pages of Nature and elsewhere.”

Monica Bradford, executive editor at Science, said: “We have a large circulation and printing additional papers has a real economic cost … Our editorial staff is dedicated to ensuring a thorough and professional peer review upon which they determine which papers to select for inclusion in our journal. There is nothing artificial about the acceptance rate. It reflects the scope and mission of our journal.”

Emilie Marcus, editor of Cell, said: “Since its launch nearly 40 years ago, Cell has focused on providing strong editorial vision, best-in-class author service with informed and responsive professional editors, rapid and rigorous peer-review from leading academic researchers, and sophisticated production quality. Cell’s raison d’etre is to serve science and scientists and if we fail to offer value for both our authors and readers, the journal will not flourish; for us doing so is a founding principle, not a luxury.”

NOBEL PRIZE IN PHYSIOLOGY AND MEDICINE 2013.


The Nobel Assembly at Karolinska Institutet has today decided to award

The 2013 Nobel Prize in Physiology or Medicine

jointly to

James E. Rothman, Randy W. Schekman
and Thomas C. Südhof

for their discoveries of machinery regulating vesicle traffic,
a major transport system in our cells

Summary

The 2013 Nobel Prize honours three scientists who have solved the mystery of how the cell organizes its transport system. Each cell is a factory that produces and exports molecules. For instance, insulin is manufactured and released into the blood and chemical signals called neurotransmitters are sent from one nerve cell to another. These molecules are transported around the cell in small packages called vesicles. The three Nobel Laureates have discovered the molecular principles that govern how this cargo is delivered to the right place at the right time in the cell.

Randy Schekman discovered a set of genes that were required for vesicle traffic. James Rothman  unravelled protein machinery that allows vesicles to fuse with their targets to permit transfer of cargo. Thomas Südhof revealed how signals instruct vesicles to release their cargo with precision.

Through their discoveries, Rothman, Schekman and Südhof have revealed the exquisitely precise control system for the transport and delivery of cellular cargo. Disturbances in this system have deleterious effects and contribute to conditions such as neurological diseases, diabetes, and immunological disorders.

How cargo is transported in the cell

In a large and busy port, systems are required to ensure that the correct cargo is shipped to the correct destination at the right time. The cell, with its different compartments called organelles, faces a similar problem: cells produce molecules such as hormones, neurotransmitters, cytokines and enzymes that have to be delivered to other places inside the cell, or exported out of the cell, at exactly the right moment. Timing and location are everything. Miniature bubble-like vesicles, surrounded by membranes, shuttle the cargo between organelles or fuse with the outer membrane of the cell and release their cargo to the outside. This is of major importance, as it triggers nerve activation in the case of transmitter substances, or controls metabolism in the case of hormones. How do these vesicles know where and when to deliver their cargo?

Traffic congestion reveals genetic controllers

Randy Schekman was fascinated by how the cell organizes its transport system and in the 1970s decided to study its genetic basis by using yeast as a model system. In a genetic screen, he identified yeast cells with defective transport machinery, giving rise to a situation resembling a poorly planned public transport system. Vesicles piled up in certain parts of the cell. He found that the cause of this congestion was genetic and went on to identify the mutated genes. Schekman identified three classes of genes that control different facets of the cell´s transport system, thereby providing new insights into the tightly regulated machinery that mediates vesicle transport in the cell.

Docking with precision

James Rothman was also intrigued by the nature of the cell´s transport system. When studying vesicle transport in mammalian cells in the 1980s and 1990s, Rothman discovered that a protein complex enables vesicles to dock and fuse with their target membranes. In the fusion process, proteins on the vesicles and target membranes bind to each other like the two sides of a zipper. The fact that there are many such proteins and that they bind only in specific combinations ensures that cargo is delivered to a precise location. The same principle operates inside the cell and when a vesicle binds to the cell´s outer membrane to release its contents.

It turned out that some of the genes Schekman had discovered in yeast coded for proteins corresponding to those Rothman identified in mammals, revealing an ancient evolutionary origin of the transport system. Collectively, they mapped critical components of the cell´s transport machinery.

Timing is everything

Thomas Südhof was interested in how nerve cells communicate with one another in the brain. The signalling molecules, neurotransmitters, are released from vesicles that fuse with the outer membrane of nerve cells by using the machinery discovered by Rothman and Schekman. But these vesicles are only allowed to release their contents when the nerve cell signals to its neighbours. How is this release controlled in such a precise manner? Calcium ions were known to be involved in this process and in the 1990s, Südhof searched for calcium sensitive proteins in nerve cells. He identified molecular machinery that responds to an influx of calcium ions and directs neighbour proteins rapidly to bind vesicles to the outer membrane of the nerve cell. The zipper opens up and signal substances are released. Südhof´s discovery explained how temporal precision is achieved and how vesicles´ contents can be released on command.

Vesicle transport gives insight into disease processes

The three Nobel Laureates have discovered a fundamental process in cell physiology. These discoveries have had a major impact on our understanding of how cargo is delivered with timing and precision within and outside the cell.  Vesicle transport and fusion operate, with the same general principles, in organisms as different as yeast and man. The system is critical for a variety of physiological processes in which vesicle fusion must be controlled, ranging from signalling in the brain to release of hormones and immune cytokines. Defective vesicle transport occurs in a variety of diseases including a number of neurological and immunological disorders, as well as in diabetes. Without this wonderfully precise organization, the cell would lapse into chaos.

 

James E. Rothman was born 1950 in Haverhill, Massachusetts, USA. He received his PhD from Harvard Medical School in 1976, was a postdoctoral fellow at Massachusetts Institute of Technology, and moved in 1978 to Stanford University in California, where he started his research on the vesicles of the cell. Rothman has also worked at Princeton University, Memorial Sloan-Kettering Cancer Institute and Columbia University. In 2008, he joined the faculty of Yale University in New Haven, Connecticut, USA, where he is currently Professor and Chairman in the Department of Cell Biology.

Randy W. Schekman was born 1948 in St Paul, Minnesota, USA, studied at the University of California in Los Angeles and at Stanford University, where he obtained his PhD in 1974 under the supervision of Arthur Kornberg (Nobel Prize 1959) and in the same department that Rothman joined a few years later. In 1976, Schekman joined the faculty of the University of California at Berkeley, where he is currently Professor in the Department of Molecular and Cell biology. Schekman is also an investigator of Howard Hughes Medical Institute.

Thomas C. Südhof was born in 1955 in Göttingen, Germany. He studied at the Georg-August-Universität in Göttingen, where he received an MD in 1982 and a Doctorate in neurochemistry the same year. In 1983, he moved to the University of Texas Southwestern Medical Center in Dallas, Texas, USA, as a postdoctoral fellow with Michael Brown and Joseph Goldstein (who shared the 1985 Nobel Prize in Physiology or Medicine). Südhof became an investigator of Howard Hughes Medical Institute in 1991 and was appointed Professor of Molecular and Cellular Physiology at Stanford University in 2008.
