The findings of medical research are disseminated too slowly

That is about to change

ON JANUARY 1st the Bill & Melinda Gates Foundation did something that may
help to change the practice of science. It brought into force a policy,
foreshadowed two years earlier, that research it supports (it is the
world’s biggest source of charitable money for scientific endeavours, to
the tune of some $4bn a year) must, when published, be freely available to
all. On March 23rd it followed this up by announcing that it will pay the
cost of putting such research in one particular repository of freely
available papers.

To a layman, this may sound neither controversial nor ground-breaking. But
the crucial word is “freely”. It means papers reporting Gates-sponsored
research cannot be charged for. No pay walls. No journal subscriptions.
That is not a new idea, but the foundation’s announcement gives it teeth.
It means recipients of Gates’ largesse can no longer offer their wares to
journals such as Nature, the New England Journal of Medicine or the
Proceedings of the National Academy of Sciences, since reading the contents
of these publications costs money.

That will hurt. Publication in such Premier-league journals is the stuff
careers are built on. But it will also hurt the journals themselves. Their
prestige is based on their ability to pick and publish only the best. If
some work is out of bounds to them, no matter how good it is, that will
diminish their quality. And if other patrons of science follow suit, those
journals’ businesses could begin to crumble. Moreover, by actively
directing the beneficiaries of its patronage towards the repository in
question, set up last year by the Wellcome Trust (after Gates, the world’s
second-largest medical-research charity), the foundation is pointing to a
specific type of alternative—and to a future for scientific publication
that, if not completely journal-free, is likely to be at least,

Wellcome to the 21st century

Periodical journals have been the principal means of disseminating science
since the 17th century. The oldest still around, the Philosophical
Transactions of the Royal Society (pictured above), appeared first in 1665.
Over the intervening three and a half centuries journals have established
conventions for publication—such as insisting on independent (and usually
anonymous) peer review of submissions—that are intended to preserve the
integrity of the scientific process. They have, though, come under
increasing attack in recent years.

One criticism, in a world where most non-commercial scientific research is
sponsored by governments, is that there should be no further charge for
reading the results of taxpayer-funded work. Journals, in other words,
should have no cover or subscription price. A second is that the process of
getting a paper published takes too long. Months—sometimes years—can pass
while a hopeful researcher first finds a journal willing to publish, and
then waits for peer review and the negotiation of amendments. That keeps
others in the field in the dark about new results for longer than is really
necessary, and thus slows down the progress of science. Third, though this
is less easy to prove, many researchers suspect that anonymous peer review
is sometimes exploited by rivals to delay the publication of competitors’
papers, or, conversely, that cabals of mates scratch each others’ backs,

To these criticisms, another may be added, which is not the fault of
journals, but still needs addressing. This is the unwillingness of many
researchers to publish the data on which their conclusions are based. Some
journals do insist on full disclosure of data, but not all are so
particular. And, even then, the data in question will not see the light
until publication day.

Partial solutions to some of these problems have been tried. The Gates
foundation is experimenting with carrots, as well as sticks. It has offered
the publishers of one top-flight journal, Science, $100,000 to make papers
published this year about Gates-sponsored research free to read from the
beginning. If this goes well, the experiment may be extended to other
publications. Similarly, there is a movement among some publishers to make
papers free to the reader by charging the authors (and therefore,
ultimately, their patrons) for the costs of publication—usually in the
range of $2,000-$3,000 per paper. But many now think these are
half-measures, and that a real revolution in the idea of scientific
publishing is needed.

Part of science has already undergone such a revolution. Since 1991
physicists have been able to deposit early versions of their papers, known
as preprints, in an online repository called arXiv (the “X” represents a
Greek “chi” rather than a Latin “ex”). ArXiv is paid for by Cornell
University Library, the Simons Foundation, a charity, and through fees from
around 200 members (mostly universities). Over the years the number using
it has increased, to the point where around 300 preprints are deposited
every day.

This sort of “pre-publication” is rapidly becoming physics’s method of
choice. Depositing a paper in arXiv both establishes that a researcher has
been the first to arrive at a discovery and makes that discovery available
immediately to others. It does not provide formal peer review, but
physicists are not shy of criticising the work of others, so a lot of
informal (and un-anonymous) feedback can accumulate rapidly. This potential
flak is a deterrent to publishing half-baked work. Nor does appearing in
arXiv preclude later publication in a journal. The editors of periodicals
were once sniffy about accepting material previously available elsewhere.
In physics, they can no longer afford this luxury.

The Gates foundation’s announcement is part of an attempt to extend this
idea to the rest of science, particularly biomedical research. Biomedical
equivalents of arXiv exist, but they are not much used. One of the largest,
bio Rxiv, received around 600 submissions in February. That is but a
fifteenth as many as arXiv, even though many more biomedical papers are
published per year than physics papers.

Why biologists have failed to follow physicists’ lead is unclear. It may
simply be a historical accident. ArXiv was started before most journals
went online, so was initially more distinct from such journals than online
databases are now. By the time biologists, less computer-literate as a clan
than physicists, caught up with the idea, the online-offline distinction
had blurred, and the journals saw online repositories as rivals. But
whatever the cause, the result was clear: an unwillingness by
non-physicists to embrace preprints.

The time, however, seems ripe to change that. Though its absolute numbers
are still low, the use of bio Rxiv is growing fast (see chart). And it is
not just outside nudges that are bringing this sort of thing about. In
February, for example, ASAPbio, a group of biologists who are trying to
promote the use of preprints, began looking for bidders to create a website
which will index all life-science preprints published in public

Outside nudges do help, though. It will not harm ASAPbio’s chances of
success that its plan has the backing of America’s National Institutes of
Health, the country’s main source of taxpayer finance for medical research.
And other philanthropic organisations besides the Gates foundation are also
pushing in the same direction. The Wellcome Trust’s creation of the
repository Gates has just joined is one example. Another is the Chan
Zuckerberg Biohub in San Francisco, brainchild of Mark Zuckerberg, a
founder of Facebook, and his wife, Priscilla Chan. In February the Biohub
announced it would disburse $50m to 47 local scientists on condition they
made their work available as preprints.

There is even room for commerce in this brave, new world. The
Wellcome-Gates repository is actually run by a firm called F1000, that also
has its own preprint repository, F1000Research. This operates in a slightly
different way from arXiv and its imitators in that its does include a
formal process of peer review. F1000’s review process involves named rather
than anonymous reviewers, which many regard as a strength. But who those
reviewers should be is suggested by a submitted paper’s authors, which
carries obvious risks of partiality. Revenue comes from a fee of up to
$1,000 that authors pay on submission.

The wider use of preprints might also help reduce the problem of
pre-publication data-hoarding. Once a preprint is published, its authors
need not fear that others will take credit for their work. And it is
becoming easier to make data available in a way that lets the originator
retain control and garner credit. Sites such as Figshare let researchers
assign a unique alphanumeric code (called a Digital Object Identifier) to
data sets, figures, video and so on, meaning their origins are clear.

None of this necessarily means that non-physicists will eschew journals and
rush to publish their work in open repositories. Over time, though, more
may come to see the advantages of doing so. As more researchers submit
preprints and make their data available to others, they may find the
comments they receive regarding their work helpful. Even the kudos of
publication in the premier journals may slowly fade in the face of data
about a piece of work’s actual, rather than potential, impact (see
article). Having survived three and a half centuries, scientific journals
will no doubt be around for a long time yet. With luck, though, they will
return to being science’s servants, rather than its ringmasters.
