Talking Biotech 182 – Insect Resistant Cowpea in Africa

Image
The link to this week's podcast is here.  Cowpea is a critical crop in Western Africa.  It is consumed by millions daily, but also feeds livestock, all the while providing important nitrogen fixation for the farm.  Cowpea cultivation is threatened by  Maruca vitrata , a butterfly who’s caterpillar stage feasts on the beans within the cowpea pod. Scientists in Nigeria have implemented a strategy using the Bt protein to fight against this pest.  Today’s podcast interviews Francis Onyekachi, Program Manager for the West African Maruca Resistant Cowpea Project.  He talks about the crop, the technology, and the strategy to ensure its continued efficacy.  Co-hosted by Nigerian native and University of Florida graduate student Modesta Abugu. 

Does High Fructose Corn Syrup Cause Colon Cancer?

Results of a recent study in mice need a little clarification. The article caught my eye because it said that high fructose corn syrup (HFCS) “enhances tumor growth in mice” and it was published in the top-notch journal  Science . The article mentions soft drinks and sugar sweetened beverages (SSBs) right in the abstract. It is no wonder that the general media got quite a rush from the story. But is that what the data really showed? The study by  Goncalves et al  is a nice piece of work. The researchers used mice missing a key tumor suppressor as a model. Colorectal cancers develop from a well-described progression of genetic changes before cells become malignant. Researchers have developed mice that are missing some of the biochemical hardware that keep cells from becoming cancerous. They possess errors in a gene that represses one major step toward cancer, so they are prone to develop tumors. The researchers used these mice to perform the experiments, as the tumor-prone mi

De-Platforming. A Power Move

I'm interested in debate. I need to get it right. Despite what people may say, I'm not an out of touch, arrogant scientist.  I'm interested to learn more and understand other perspectives.   That's why I give people the benefit of the doubt. I have learned from others, and I have changed my mind.  I have been wrong, and I'm glad to admit that.  At the same time I've stood up for science. I've endured endless hassle and anger, hideous allegations and propagation of rumor and hate.   Thacker is glad to use public records and distribute my social security number. I had to get it changed after he decided to make it public.  I can take it.  I know the truth, and anyone with half a brain can see what is reality, really is.  But there comes a time that you have to take the microphone out of the hands of the chronically delinquent.  In my case, Paul Thacker, Michael Balter, and some folks I met on Kauai have decided to make a daily spectacle of smear. 

Words Used Out of Context

Image
Over the last two decades I have endured daily hassle from folks dedicated to besmirching the reputations of scientists. What a proud existence that must be.  One great example resurfaced last night.  I first wrote about it on September 7, 2015.  The image shows me and a quotation, pulled from nearly 50,000 pages of email voluntarily turned over to activist groups.   There was no evidence of malfeasance, nothing unethical or illegal.  All they could do to make me look bad was pull a quotation from context.  Almost four years later that same graphic is being used by activists to impugn my integrity.   The best part is, this is all they have, and it is a distortion of what was actually said.  The email was not between me and Monsanto.  It was between me and a friend that works there.  As we go through our careers as plant scientists it is not unusual to connect with people in industry. We meet their spouses, see pictures of their kids, trade dog stories-- they are peo

Book Review: Feeding You Lies by "The Food Babe" Vani Hari

Image
Many people say that I should ignore Vani Hari and her new book, Feeding You Lies - How to Unravel the Food Industry's Playbook and Reclaim Your Health . Don’t give her the attention. However, I’m mentioned prominently throughout the text, portrayed as an industry insider, paid to harass her and derail her efforts to rid the world of molecules with names we can’t pronounce.   On her press junkets she spins wild tales of being a victim, targeted by a concerted effort between me and evil corporations to destroy her credibility. There really was no such thing. Hari used the Freedom of Information Act to gather tens of thousands of my emails at taxpayer expense—and found nothing.   Zero. But instead of saying that in her book, she manufactured false stories and associations, picking out sentences just to paint me in a negative light. We’ll get back to that. She certainly goes after me as a paid corporate dupe that is financed to attack her.  I'm actually a public

Poisoning Agriculture

Image
Sloppy Journalism Continues to Tarnish the Perception of Food Safety and the Processes that Produce It The daily reports about how agriculture is killing us are certainly alarming. However, when I carefully examine each report the sensational headlines never seem to match reality. The claims originate usually from either unpublished reports, or re-interpretations of legitimately-published work where the conclusions have little to no relationship to the scandalous headline. Today’s example came to me via Twitter when I read the post to the left. Pesticides associated with amyotrophic lateral sclerosis (ALS; Lou Gehrig's Disease) progression? Okay, I’ll take a look at the data and see what they authors found.  The referenced study is here. The authors analyzed 167 cases of ALS, measured blood levels of select compounds, and then monitored disease progression. The authors found associations between levels of specific organic compounds and the progression of disease. But

Blog Post from September 6, 2015

In light of recent events, I decided to visit my blog from September 6, 2015, the day that Eric Lipton's article was published.  Here it is again for you to compare and contrast against claims made by Lipton and others. That is all.  1. What is your relationship with Monsanto? I have no formal relationship with the company.  Friends, former students, colleagues from previous jobs work there.  They once made a relatively small donation to my university to cover travel/production costs of my science communication program in August of 2014.  The entire original amount was reallocated to a campus charity. Monsanto does not fund my research and never has. I have spoken at the company twice about science communication and enjoyed collegial hospitality. As is clear by emails, I'm glad to share thoughts and opinions with them on science communication. I hold no formal capacity in this regard. I do this with any company and show no special favor to Monsanto. 2. What is y
