Big Pharma and academia becoming more and more cozy

I recently attended the Alzheimer's Disease Keystone meeting in Keystone, CO and became more acutely aware of something than ever before: academia and drug companies really like one another. Sure, the latter always loved the former, since collaborating with university-based scientists often made the publications arising from the private sector look a little more legit. On the contrary, the reciprocity in this relationship has not always been there. There is without a doubt some sub-disciplinary differences in this complex relationship, but in the basic science departments that I lurked around, if you were associated with a company (or worse, left academia for a position there, succumbing to the power of the Dark Side), there was always talk of whether or not you could be trusted. Because companies need publications to prove the legitimacy of their product, right? And the legitimacy determines how much money everyone makes, right? So with such conflicts of interest, could the scientist, or the data being produced by these people, be trusted?

What to do with your unfunded proposals - place them in a centralized repository?

I would say no. Grant proposals are a precious commodity, especially in this day and age of reduced funding and evaporating money. However, in a recent Nature correspondence, Dr. Noam Harel describes his vision for a centralized grant repository, ideally open to the public, where researchers could place their best ideas, allowing various funding agencies to discover the plans most-suited to their respective agendas. Dr. Harel likens this potential web manifestation to something like eBay, Facebook or Google, but for scientists and funding agencies. A more apt analogy might be Monster.com, with both sides searching for their ideal match, and a long-term relationship (perhaps I am now making it sound more like eHarmony.com...).

When it comes to the integration of scientific communication and technology, I am extremely optimistic, and although I don't reject Dr. Harel's idea entirely, I just don't see it taking off in its presently-proposed form.

NN Joins Neuroscience Peer Review Consortium

When the community is overburdened by peer review, it's everybody's problem. As of today, Nature Neuroscience has become part of the solution by joining the Neuroscience Peer Review Consortium, a flexible system that allows voluntary participation by authors, referees and editors. Here are more details, from our April editorial:

Haihong Ye: Amazing changes in Chinese neuroscience over the past decade

[This is the inaugural post for a new feature at Action Potential. Periodically, we will provide insights from a regional correspondent on the interesting news, changes, or issues particularly affecting neuroscience in a particular location. Today's post is from one of our Asian correspondents, Haihong Ye of the Institute for Biophysics in the Chinese Academy of Sciences. She reflects on the dramatic changes that have occurred within Chinese neuroscience during her decade-long absence from this now-flourishing community. We examined these issues in our March editorial, but now invite you to provide your opinion. - N.G.]

Over the past 10 years, especially the last five, the whole world has been amazed by the Chinese economy. To me, however, the improvement in biological science research in China is much more amazing. In the summer of 1998 I left Beijing and went to the US to pursue a Ph.D. in neuroscience. In 2007, after nine years of graduate study and post-doc training abroad, I came back to Beijing, seeking opportunities for further career development. What a difference some strong funding and visionary directives, not to mention a decade, can make.

Neuroscience and Web 2.0: Participation may vary

In the last couple of years, after the recent explosion in the number of resources where scientific discussions can take place rapidly and without boundaries (i.e., using the internet), one could easily have predicted that we were on the cusp of a revolution; the way in which scientists communicated with each other regarding data was about to change forever. Although poster session chatter at your favorite scientific meeting was never going to be replaced, now researchers could interact, trade ideas and get feedback from anyone, anywhere, at any time. Sounds pretty good, right? Unfortunately, it doesn't seem like neuroscientists are taking advantage of these cool new offerings. I could extrapolate to biology in general, but for more simplicity (and other obvious reasons), let's stick to what we know best.

Retraction reaction

Nobel prize-winning neuroscientist Linda Buck has retracted a 2001 Nature paper. In the retraction in this week's Nature, the authors report difficulty replicating the data and 'inconsistencies' between the original data and figures and data printed in the paper. Buck told Nature reporter Heidi Ledford that the figures and data in question were contributed by the first author, Zhihua Zou, who was unavailable for comment.

This is the highest profile retraction that I can recall in neuroscience, but so far, there has been little fallout. Perhaps that's because the original findings were notable only in the neuroscience community rather than in the general public. Regardless, it indicates that neuroscience and its well known labs are not immune from fraudulent data. Although I admire Buck's swift and direct action, it concerns me that the first author has been assigned the lion's share of the blame. This seems like a familiar refrain, and I find it troubling.

Anti antidepressants

By now, you've likely read a shocking headline questioning the effectiveness of the latest generation of antidepressants. Kirsch et al. report that selective serotonin reuptake inhibitors (SSRIs) are only slightly more effective than placebos at reducing depression in a meta-analysis of US Food and Drug Administration (FDA) data. Are these data really worth all the fuss?

Pet sematary

A woman in the US has decided that she loved her pit bull (named Booger) so much, that having him all over again is definitely worth the $150,000 price tag. I saw this story in the BBC, reporting how a Korean company, RNL Bio, has taken its initial order for pet dog cloning, the first such venture of commercial scientific canine cloning (a pet cat was first cloned in 2004). The lead scientist at RNL Bio, Dr Lee Byeong-chun, had previously worked with disgraced stem cell scientist Dr Hwang Woo-suk, whose fraudulent publications created quite a stir (we referred to that scandal on Action potential here.)

The client, Bernann McKunney, gave RNL Bio ear tissue from "Booger", preserved by an American biotech firm before the dog died 18 months ago. Ms. McKunney had become quite devoted to her dog after she claimed it saved her life, coming to her aid while she was being attacked by another dog, an encounter that cost her an arm. For those of you wishing you had the six figures required to re-create your close canine companion, never fear, RNL Bio's marketing director, Cho Seong-ryul believes that the cloning costs should come down to be under $50,000, as the industry begins to "take-off".

Separate but not equal?

If a disease affects men and women differently, does the disease's mechanism differ by sex? My guess would be no. However, a recent article has me wondering. Schizophrenia symptoms, age of onset, and disease course differ in men and women, and some researchers report increased risk of schizophrenia in men relative to women. Now Shifman et al. report a single nucleotide polymorphism (SNP) associated with schizophrenia in women but not men in a recent article in PLoS Genetics.

Harvard open-access policy – can you please be more specific?

The Faculty of Arts and Sciences (FAS) at Harvard University voted Tuesday to adopt an open-access policy, providing a free repository for finished papers, according to a recent press release. This move will allow for greater dissemination of scholarly work conducted at Harvard, says Stuart Shieber, a professor at FAS. Shieber states that a combination of a restrictive publishing system and the “astronomical” cost of journals have led the Harvard professors to support such a venture. An official description of the proposal that was actually discussed by the FAS on Tuesday is here.

As my colleague from Nature Precedings, Hilary Spencer, points out in a recent Nature Network forum, this entire policy is very vague with regards to what is meant by the scholarly article or the "final version." Is that the final, journal-produced PDF? The peer-reviewed, unpublished, non-copy-edited version? The non-peer-reviewed pre-print? According to an analysis written up on TheScientist.com, this mandate would require that published articles be submitted. However, go back and re-read the original proposal and tell me where it says that explicitly.
