Hormones, antibiotics, GMOs… A trip to the grocery store is a battle against fear and guilt. From marketers to activists, there is a concerted effort afoot to use fear, shame and guilt to shape consumer food choices. Sadly, this is happening at a time of unprecedented abundance, yet a time when farmers are facing difficulty in competing against low prices and endless regulation. Michele Payn is a popular speaker and author that is here to talk about her book Food Truths. The book analyzes the ho...

Aflatoxins are trace compounds produced by certain fungi, and represent a legitimate food safety risk. These fungi grow on corn, peanuts and other crops, especially in warm, humid areas that lack fungal control measures. They have been connected to numerous human diseases, primarily liver cancer, but also cause problems in livestock fed contaminated grain. Dr. Monica Schmidt of the University of Arizona has a good solution. Her team has expressed an RNA sequence in corn that matches the genetic ...

There are no compounds that can be sprayed to fight plant viruses, so plant protection requires managing the insects that spread them. This means use of insecticides that cost money and have potential impacts, such as affecting non-target insects. Scientists have successfully used RNA-based strategies to fight plant viruses, but that has been through use of transgenic approaches where genetic material of the virus is expressed by the plant cell, triggering resistance. Dr. Neena Mitter uses a dif...

I’ll always remember 2016 as an eclectic mix of hell and success. We learned a lot about how to engage the public and got lots of practice. We took a lot of heat, suffered lots of personal and professional damage and defamation. We got through it by telling the truth, being soft, and enjoying a conversation about science with the world’s experts. Ultimately the efforts led to wonderful recognition that maybe provided a better conduit for the message. But what can we do better in 2017? Today’s po...

Today’s episode is born of frustration. Fear-mongering non-experts are abusing improper interpretations from an available herbicide detection kit to make claims that herbicides are now found in vaccines. Namely, they seek to find glyphosate, the active ingredient in Roundup. They use a kit you can buy on the internet, but fail to use it in the way it is designed. Instead of using it on water, they use it on complex mixtures that yield false positives that are interpreted as legitimate signals. S...

One of the amazing success stories of genetic engineering is the eggplant, known as the “brinjal” in Asia and the “aubergine” in Europe. In the west it is occasional table fare, yet in many parts of Asia it is a daily staple. Farmers in Bangladesh and India rely on doses of old-school insecticides to protect their crop, up to eighty a season, and not always with appropriate protection equipment. The problem is insects that bore into the plant and into the fruit, destroying a crop. One solution h...
