Do wild animals avoid GMO corn? Join the experiment!

This is exciting – a group of serious scientists have launched a crowd-sourced experiment to test the hypothesis that wild animals such as squirrels and deer prefer non-GMO corn, and avoid GMO corn. It's exciting because you can participate – it's easy.

Anecdotal reports suggest that animals avoid eating genetically engineered or GMO corn when given a choice, while others suggest that animals have no preference. With the right materials, this is an easy experiment to do, but there are no peer-reviewed, published scientific studies to answer this question – yet.

In this experiment, we will send ears of GMO and non-GMO corn to volunteers. Adults and children, individuals and classrooms can be part of the first Citizen Science experiment to test claims about GMOs. Everyone’s results will be combined in a peer-reviewed scientific journal article

I just listened to the Talking Biotech podcast #20 on the corn experiment. Kevin Folta and – Karl Haro von Mogel do a deep dive into the design of the experiment. If you donate $25 or more at you will receive your own kit. And you can put your school on the waiting list for a free experiment.

Donate, contribute a bit of your time and you can be part of a real science project. You will learn how an experiment like this has to be designed so that the results will survive peer-review. And if the hypothesis is supported by the data I think the resulting peer-reviewed paper might make the cover of Science! All the supporters will be listed as contributors in the paper.


New York Times: Your reporting fed McCarthyite attacks on Kevin Folta


Jean Goodwin is an expert in rhetoric at Iowa State. Dr. Goodwin specializes in achieving useful communication among parties who deeply disagree.

My primary research/teaching focus is in argumentation studies; I study how citizens who deeply disagree can nevertheless manage to coordinate a worthwhile exchange of reasons. In the past few years, I’ve begun looking at the special problems experts face when they attempt to contribute the public sphere–a project with several threads under the general heading, Between Scientists and Citizens. While my social science colleagues can provide valuable perspectives on how scientists can communicate more effectively, as a humanities scholar I am focused on the values issues–why scientists should communicate, what they should hope to accomplish by doing so, what roles they can appropriately play in civic deliberations. Case studies of such issues of science communication ethics are available on the website of our NSF-funded project, Cases for Teaching Responsible Communication of Science.

If that sounds like good preparation to analyze what the New York Times did to Kevin Folta, then you would be right. If you explore Jean’s blog Between Scientists and Citizens you will get some comfort that you are around serious people. I look to see who else the writer links, finding another world-class science communicator, Roger Pielke Jr. And Andy Revkin. So I was frankly excited after I began reading her short essay on the Folta case:

So, follow below the fold to find my defense of these three claims:

  1. Folta is an outstanding science communicator.
  2. He is being targeted by McCarthy-style attacks.
  3. The New York Times and the Chronicle of Higher Education failed to resist the McCarthyism.

1. Folta = Science Communication

Many have been calling for bench scientists to invest more time engaging the public. Having seen Folta present and having looked over some of his outreach efforts, it’s my view that he is a model science communicator and that any scientist wanting to jump into public communication should learn from him.* I may write another blog post about it, but to put it briefly, Folta shares his passion for his research and makes clear his respect for each and every member of his audience.§¶

*One thing they should learn right off is to be ultra-scrupulous in declaring all sources of funding–Folta has admitted sloppiness in this, and he is paying the penalty.

§ Folta loves his listeners; that sounds sappy, but it isn’t. Listen to the talk he gave at my university, paying attention his interactions with those skeptical of GMOs. Be aware, it’s over two hours long–because he was willing to stay there and respond, respectfully, to every single question and challenge. Or take a look at one story of what talking with Folta feels like from the audience point of view.

¶ Folta loves his listeners, with one exception: he clearly loathes those who he perceives to be a core group of science-distorting anti-GMO fanatics. This also is a mistake that he is paying for: he should love them, too; or at least, speak as if they did not exist.

My score on Jean’s defense of point #1 is “about perfect”. We could add a link to Talking Biotech podcast where it is so easy to access current talks and interviews that help the listener appreciate who Kevin Folta really is (try to match up the real Kevin Folta with the NY Times portrayal). If you are new to this topic you should definitely browse through Dr. Folta’s writings at Illumination blog. Especially read the comments, paying attention to the hostile questions and Dr. Folta’s remarkable patience in answering. If you find any evidence that you are reading a “shill for Big Seed” please let me know in the Comments.

Next comes the discussion of 2. McCarthyism and 3. Failures in the reporting, closing with this:

So in sum: The New York Times and the Chronicle did a poor job on this story, helping perpetuate McCarthyite attacks on a scientist who–unlike most–has bothered to reach out to the public. For shame!

Get on over there to Between Scientists and Citizens – where you can ask your questions or agree/disagree passionately in the comments.


“I’ve been FOIA ed”: Alison Van Eenennaam on being in crosshairs of anti-GMO activists

Alison Van Eenennaam, Ph.D. is an animal geneticist and Cooperative Extension specialist in the Department of Animal Science at the University of California, Davis.

Dr. Alison Van Eenennaam has been targeted by USRTK and their Big Organic backers. Please read her post in full. Her “offense” which put her in the crosshairs of the organic interests is that she has “engaged in public discussion about GMOs”. That must be stopped. Only the Whole Foods message is to be heard.

Following are some of her observations drawn from experience engaging with Dr. Kevin Folta.

FOIA attacks get personal

In the meantime, I have watched with increasing distress at the way that Dr. Kevin Folta, of the University of Florida, also a FOIA request target, has been portrayed subsequent to the public release of his FOIAed emails. Why distress? Because I know Kevin and I know how deeply he cares about science. I have had dinner at his house, and we recently did an early morning fitness “bootcamp” when he was in Davis. I consider him a friend, and his job is not that different than mine—we are both science communicators who talk about breeding; he talks about plants, I talk about animals.

(…snip…) I have observed Kevin giving biotechnology presentations on several occasions. He provides evidence-based, factual content. He reports on his own published research results (not sponsored by industry), and also reports on the scientific consensus that the genetically engineered crops currently on the market are safe to eat – a conclusion reached by every major scientific organization in the world. I have seen how he speaks with passion about science. Perhaps to his detriment, he does not censor his opinions in person or in email correspondence. He says what he thinks. He spends an inordinate amount of his free time on nights and weekends doing science communication. None of that could be considered wrongdoing. In fact it’s just the opposite: he’s responsibly communicating the up-to-date science, as he is mandated to do as a scientist at a public university.

(…snip…) Today, the scope of the requests has moved well beyond GMO Answers and Proposition 37. The real target seems to be prominent scientists affiliated with land-grant universities across the United States engaged in public discussion about GMOs. That description fits me; I have been involved in public communication around this topic, and many other related controversial topics. You do not need to look too far to find controversial topics in animal agriculture. I have spoken about cloning, genomic selection, the AquAdvantage salmon, animal biotechnologies, GMOS, coexistence of different agricultural production and marketing systems and food labeling.

These attacks are a form of “Asymmetric Warfare” against public scientists who openly discuss genetic engineering technology. I say Asymmetric because the attackers have whatever resources they may need – including funding for lawyers, public relations firms and researchers. Dr. Van Eenennaam may get some help from the UC system legal staff to ensure that the surrendered documents do not encroach on the rights of third parties. Beyond that her defense falls on her shoulders (and family). Political operative Gary Ruskin has his whole team attacking – he can just go home and forget it. Dr. Van Eenennaam doesn’t have the option to turn over her defense to a team of professionals.

If you shop at Whole Foods Markets (for example) you should think carefully whether you wish to be supporting this attack on public scientists. If you continue to shop at Whole Foods Markets, Dr. Bronner’s Magic Soaps, Joe Mercola etc. these attacks will never stop because those financial interests benefit from muzzling scientists who speak the forbidden. The shareholders of Whole Foods et al benefit every time the New York Times runs front page articles ridiculing scientists who explain the forbidden knowledge.

The organic/natural interests want moms to be afraid of food sold by anyone else. They have no ethics, but do have barrels of money and buildings full of lawyers.

Open letter from 21 top European plant scientists to decision makers in Europe


The de facto moratorium on transgenic plant approvals has been detrimental for applied plant science and has effectively eliminated possibilities for publicly funded scientists and small companies to address the big challenges for society. The resulting reduced competition has enhanced the dominance of the major seed and agrochemical corporations. We believe that a fundamental revision of GM regulation is needed that strictly follows principles of a science-based evaluations and approvals, based on evaluation of the trait, rather than the method by which it is achieved.

Image left is signatory Professor Stefan Jansson Umeå Plant Science Centre, Department of Plant Physiology, Umeå University, Sweden 

October 30, 2014 a group of Europe’s leading plant scientists sent a straight-talking nastygram to the EU authorities (original PDF here). I’ve reproduced the letter in the following paragraphs (signatories at the end).

We all depend on plants for providing us with food, building material, textiles, medicine and fuel. Among the greatest challenges facing mankind are the provision of healthy and nutritious food, feed and fuel to a burgeoning population using agricultural and forestry practices that are environmentally and economically sustainable. Thanks to basic research on plants, we now understand well how plants grow, how they protect themselves against disease and environmental stress, and what factors limit production in agriculture and forestry.

Europe has a strong history of plant science. Robert Hooke introduced the concept of the “cell” in the 17th century after looking at cork slivers in his microscope. Carl Linnaeus developed systematics after his studies of plants and Gregor Mendel deciphered the laws of genetics after meticulous counting of plants in his monastery garden in Brno. Plant scientists discovered chromosomes, enzymes and viruses, and Charles Darwin spent a large part of his scientific career as a plant biologist; “The origin of species” starts “When we look to the individuals of the same variety or sub- variety of our older cultivated plants and animals”. Curiosity-driven plant research has been important both to deepen our understanding of nature and take benefit of it, still we lack basic understanding of many complex phenomena in plants.

27 of the “30 most cited authors in plant science” in Europe ( hold at present a position at a publicly funded research organization in Europe, and 21 out of the 27 have signed this letter. We work on various aspects of plant science, for example systematics, physiology, biochemistry, molecular biology, genetics, ecophysiology, ecology, pathology, biodiversity and effects of climate change. It is possible to perform good curiosity-driven plant science in Europe and we acknowledge our support from various funding bodies, in many respects plant science in Europe is doing well.

However, well is not good enough. Plant science has arguably contributed more to the reduction of human suffering than biomedical research, yet compared with the latter it is hugely underfunded worldwide. Norman Borlaug’s dwarf and rust-resistant varieties of wheat saved many millions from hunger. Basic science performed in Europe is also an efficient way of supporting applied research in poorer countries. We are concerned that Europe will have serious problems in reaching its ambitions of Horizon 2020: to “tackle societal challenges” and “to ensure Europe produces world- class science, removes barriers to innovation and makes it easier for the public and private sectors to work together in delivering innovation” and see three outstanding issues for decision makers to address.

First, to provide solutions to the societal challenges outlined in Horizon 2020 funding for fundamental and applied plant science should be maintained or, if possible, be increased. Most importantly, serious challenges are not adequately addressed, such as developing plants resilient to climate change, preventing loss of crop biodiversity, and creating an agriculture that avoids unsustainable demands for water, energy, fertilizers and pesticides. These tasks must be addressed in forthcoming Horizon 2020 calls.


Secondly, plant scientists must be able to perform field experiments. Many of us work with genetically modified plants as research tools, for example to understand how native plants and crops protect themselves against pests and will react to climate change. However, in most European countries permits to perform field experiments with transgenic plants are blocked, not on scientific but on political grounds. In countries that do permit field experiments, these are often systematically vandalized, causing huge scientific and financial losses. Some of us have even been threatened and had private property vandalized. This is a serious threat to science, to publicly funded research, and to European society itself. European authorities must ensure that approved and safe field experiments with transgenic plants are made possible. Vandals must be prosecuted and held accountable for scientific and financial damage.

Thirdly, Europe must allow prompt authorization of genetically modified plant varieties that have been found safe by the competent authority following a thorough science-based risk evaluation. This is essential to meet the Horizon 2020 goal of removing barriers to innovation and making it easier for the public and private sectors to work together in delivering innovation. The de facto moratorium on transgenic plant approvals has been detrimental for applied plant science and has effectively eliminated possibilities for publicly funded scientists and small companies to address the big challenges for society. The resulting reduced competition has enhanced the dominance of the major seed and agrochemical corporations. We believe that a fundamental revision of GM regulation is needed that strictly follows principles of a science-based evaluations and approvals, based on evaluation of the trait, rather than the method by which it is achieved.

Our scientific credibility comes from our work on basic plant science. Some of us also apply our knowledge to improving plants for the human society, but the reason that we make this statement is not commercial interests or hope of attracting more funding for our own research. Instead, we are seriously concerned that lack of adequate funding and safe infrastructures will relegate European basic and applied plant science to a second tier status. If plant scientists cannot apply their knowledge for the benefit of society, Europe will be unable to lead in global efforts to build a sustainable agricultural system and plant-based bio-economy. The most pressing global problems – how do deal with environmental change and secure food supply for all – arguably will only be solved with a massively increased worldwide investment in plant research.

Important transparency questions for Thacker and Seife

This is a small inquiry about “Who Benefits?”. Regarding the now-retracted PLOS blog piece “The Fight Over Transparency: Round Two“, I have been puzzling over the authors’ motivations. Who benefits from the authors’ PLOS and LA Times articles? Could it be Whole Foods Markets?

I am very keen to know where authors Thacker and Seife stand regarding mandatory GMO labeling. Why? Because their articles supported, an activist operation funded by organic industry lobby Organic Consumers Association. USRTK is in the business of

  • passing US federal mandatory GMO labeling legislation;
  • fomenting fear of foods derived from modern genertic engineering

Perhaps it is an accident that their articles were so helpful to the organic industry interests. I think we have a right to know whether the authors are neutral?

  1. What evidence can you offer for the hypothesis that you are neutral, disinterested parties?
  2. What evidence demonstrates that you agree with the global scientific consensus on the safety of current GMO crops?
  3. Why did USRTK turn over to you emails obtained under FOIA? The only reason I can imagine is that Gary Ruskin, head of USTRK believed you would generate publicity that was favorable to the organic financial interests.
  4. Can you explain why you did not contact Dr. Kevin Folta for fact-checking and comment on the since-retracted article that you were preparing to publish in PLOS?

As another example of apparent bias in favor of the organic industry — in your LA Times op-ed you wrote:

…the Union of Concerned Scientists called out a small nonprofit funded by organic food growers for sending FOIA requests to several dozen pro-GMO scientists…

It’s just plain dishonest to call US-RTK a “small nonprofit”. Could you please justify why you put your reputations on the line to make such a claim? When Gary Ruskin was running an earlier state-level campaign for mandatory GMO labeling (California Proposition 37) the financial backing was public information. Does this look like the financing of a “small nonprofit”? Note that the biggest backer for GMO labeling isn’t Big Organic, it is Big Quacka (Joe Mercola who promotes “natural products” quackery):

My question today: who are all the financial backers of the “small nonprofit” USRTK? Is it much the same special interests who backed California Proposition 37? Your followers have a right to know whether USRTK is a front for big-donor quacks like Joe Mercola ( and Dr. Bronner’s Magic Soaps All-One-God-Faith? I have trouble understanding your representation of USRTK as asmall nonprofit” when it is obvious that Ruskin’s 2012 Prop 37 backers will be happy to spend many multiples of the $9.2 million to win national mandatory labeling.

Conclusion: it’s obvious “Who Benefits” from the Thacker and Seife PLOS/LA Times articles. But we don’t know why you wrote these pieces. We don’t know why you were given FOIA emails. We don’t know whether you are pro- or anti-GE food crops. But, we do know that this is a perfect opportunity for the authors to practice Transparency in their own house!



Wilhelm Gruissem reviews “A Meta-Analysis of the Impacts of Genetically Modified Crops”

Abstract: What has long been suspected is true: genetically modified (GM) crops do have real benefits for the environment and for the economic well-being of farmers. A meta-analysis of peer-reviewed journal articles and other literature not published in journals reveals that the adoption of GM crops reduces pesticide input and increases crop yields and farmers’ income. The results confirm earlier and smaller studies and therefore are not unexpected. But they are particularly welcome for significantly informing the public debate on GM crops.

How reliable is the Klümper, Qaim Meta-Analysis? I may have missed the essential critique – but in the open-access literature this commentary gets it about right. Here we have a Swiss reviewer at ETH Zurich on the work of German researchers:

Why can this study be trusted? The authors focused on herbicide-tolerant and insect-resistant crops (maize, soybean, cotton) for which a large number of original peer-reviewed impact study reports were already available and that have also been discussed widely in the non-peer reviewed literature. They searched not only in the ISI Web of Knowledge and Google Scholar for their analysis but also used the EconLit and AgEcon Search databases because their contents are tailored to economic studies. The keyword search was unbiased and designed to retrieve peer-reviewed and gray literature reporting both positive and negative impacts. This approach was different from previous reviews of GM crop impact that were limited to peer-reviewed literature only and therefore may be been skewed toward positive results. It is often studies without such peer review, for example, [11], however, that influence the public debate and therefore detract from fact-based decision-making processes.

When dealing with a large dataset on GM crop literature, effect sizes and influencing factors are important considerations because they allow a quantification of the extent of GM crop impact rather than estimating only whether or not an impact was observed. Supported, as they are, by rigorous statistics, the results of the meta- analysis reported by Klümper and Qaim [10] convincingly show that average agronomic and economic benefits of GM crop production are significant and sizeable. Although the review was limited to insect-resistant and herbicide-tolerant maize, soybean, and cotton, the impacts are likely to be similar for canola and sugar beet, which are now grown on large acreages as well. There was no evidence that studies funded by industry had any influence on impact estimates. Studies reported in the peer-reviewed journals trended toward a higher yield impact of GM crops than the average resulting from the meta- analysis [10]. This is perhaps not unexpected because non-reviewed (gray) literature published by nongovern- mental organizations that was included in the meta- analysis typically has a negative bias.

Jonas Kathage reviews “A Meta-Analysis of the Impacts of Genetically Modified Crops”

The work was funded exclusively with public money, in part from the German Federal Ministry of Economic Cooperation and Development (BMZ) and the European Union’s Seventh Framework Programme (FP7/2007-2011). The authors are Wilhelm Klümper, a PhD student at the Department of Agricultural Economics and Rural Development at the University of Göttingen, Germany, and Matin Qaim*, a professor at the same institution and well-published researcher on the economics of GMOs.

A new meta-analysis on the farm-level impacts of GMOs – Biology Fortified, Inc. This is the breed of meta-analysis that we need – in that the authors have no conflict of interest issues of any kind [full disclosure: reviewer Jonas Kathage is a former graduate student of coauthor Matin Qaim].

As far as I can tell the authors made every reasonable effort to extract well-supported conclusions from the 147 studies. This is a big challenge — in choosing your population of studies you want to avoid cherry-picking while excluding studies that are either unreliable or do not report in ways that are consistent with the design of the meta-analysis. In the subject PLOS paper A Meta-Analysis of the Impacts of Genetically Modified Crops the authors screened 24,079 studies down to 147 that met all their criteria.


Assuming it holds up, a key result was the greater benefits experienced by developing country farmers:

Furthermore, yield gains of GM crops are 14 percentage points higher in developing countries than in developed countries. Especially smallholder farmers in the tropics and subtropics suffer from considerable pest damage that can be reduced through GM crop adoption.

Dr. Kathage agreed with the authors’ finding that industry funding did not bias the base study results towards higher yields.

Apart from the type of GM trait (IR/HT) and the type of country (developing/developed) the paper also sheds light on several other reasons why some yield results are different from others. For example, it looks at whether funding from industry is associated with higher yield estimates. It is not.

This graphic summarizes the differences between GM and non-GM crops:


Is there a superior meta-analysis that we can cite for the big picture on the results of applying GM crops?

Anti-GMO Charles Benbrook has lost his Washington State University affiliation

Some very good news today — Genetic Literacy Project has just published an in-depth profile of Benbrook – who is widely quoted as an “independent scientist” warning of the dangers of genetic engineering and GMO foods. Benbrook is widely quoted by Big Organic promoters.

Charles “Chuck” Benbrook (born 1949) is an organic proponent, researcher, industry consultant, and paid “expert witness”[1] on pesticide and GMO-related lawsuits,[2] Benbrook was formerly the research director of The Organic Center, which is funded by the organic industry and is now officially part of the Organic Trade Association. His three year affiliation with the Center for Sustaining Agriculture and Natural Resources (CSANR) at Washington State University (WSU) officially ended as of May 15, 2015. He is now no longer with CSNAR.

Benbrook was also an adjunct “research professor” at WSU until spring when he was separated from his position. However, Benbrook still represents himself in articles and interviews as being a professor at WSU and linked to CSANR–neither of which is true–and is frequently misrepresented as such by interviewers and websites, including by Wikipedia. (see below, Research, for Benbrook’s apparent misrepresentations about his employment situation and in Conflict of Interest representations of the New England Journal of Medicine). 

This is a very lengthy profile of Benbrook. If you are confronted with Benbrook as a definitive biotech expert I think you can safely refer people to this page. This is what a real-world shill looks like. It would be very illuminating to have complete access to all Charles Benbrook’s financials and emails. Has he ever corresponded with any employee of Whole Foods Markets?

Jimmy Botella: Waiter, there is a gene in my soup!

Our second nomination today for Best Biotech Talks is Jimmy Botella, Professor of Plant Biotechnology, School of Agriculture and Food Sciences at the University of Queensland. Jimmy has no pretensions, he just arrows right into the kernels of mum-fear that are exploited so profitably by the Natural Organic Foods industry:

Have you ever seen the real banana? Do you know how strawberries come about? It might come as a shock to you, but what you regard as ‘natural food’ might not be natural at all, and perhaps genetically modified (GM) food is not as bad as you think. At TEDxUQ, Jimmy Botella busted some of the fallacies we have regarding the food we eat every day, and gave us a sneak peak of what GM food actually is, and where it sits in our current society.

We think you’ll agree “This is a keeper”.

Big Organic mounts Asymmetric Warfare attack on public scientist Kevin Folta

There are misrepresentations in this PLOS BIOLOGUE guest post that need to be promptly corrected. Dr. Folta has written a brief analysis of these issues at Science20 Transparency Weaponized Against Scientists.

“Weaponized FOIA” is an appropriate term for the harassment tactic devised by Gary Ruskin and his organic industry backers. Very simply this is “Asymmetric Warfare” against forty public scientists. The attackers have whatever resources they may need – including funding for public relations firms and lawyers. Dr. Folta has only his own personal resources to defend his reputation. He doesn’t have the option to just turn over his defense to a team of professionals.

I am especially outraged at this harassment for alleged lack of transparency. I have been reading Dr. Folta since at least 2012. Why? Because when I undertook to understand the risks and benefits of modern agriculture my first task was to identify scientists that I could trust. My doctorate is Computer Science – with no training in molecular biology or horticulture. But I know how to find expertise in other fields. I find some candidate scientists that look to be credible, then put some hours into Google Scholar looking for papers and citations. It’s not rocket science to discover the researchers who have the respect of their colleagues. Then over time it’s a matter of looking at the quality and logical consistency of arguments.

For example, early on I found Penn State molecular biologist Nina Federoff. Looking at her work and CV I noted that she was a recipient of the U.S. National Medal of Science. Perhaps she is a pretty good choice for a scientist to trust. By following her citations to the work of other scientists a web of references develops. That’s how I came across prof. Kevin Folta.

Dr. Folta is very unusual in the research community because he invests a quite remarkable amount of unpaid effort into science communications. RSS is your friend for harvesting information generated by scientists like Dr. Folta who publish frequently on a personal blog, give public lectures, record podcasts, etc. All of the writing and presenting that I found – you can find too. If you do that you will quickly confirm my finding that Dr. Folta is objective and transparent to a level that sets a standard for the rest of us to live up to.

From my experience it is very clear why special interests promoting an anti-science agenda will want to discredit Dr. Folta. Hence the Asymmetric Warfare on his reputation. You can verify my claim by reading his blog Illumination and listening to his new podcast Talking Biotech. If you do that you will see that this man is not a shill for any special interest. He is exactly the sort of objective scientist that you are looking for.
