I’ve dreaded this day. I have not missed a Saturday in a long time, but after being told to end the series by the institution I have not been able to find someone that can do the work to host the podcast on a weekly basis. I hope that those that complained to the university feel good about their accomplishment. And it is people that claim to be friends of science, BTW. Right now the most prudent move is to go on a hiatus. I need time to regroup. My feeling is that I’m just going to come back, co...

Nitrogen is essential for crop growth. That reality has led to intensive crop fertilization using nitrogen fixed through the Haber-Bosch process, which has energy costs in production and transport. At the same time there are well known examples of nitrogen-fixing bacteria associated with plants, as well as some that colonize within the plant itself. Can these naturally occurring bacteria actually be used within the plant to assist in the nitrogen fixation process? Nolan Berg joins the podcast fr...

While the country of Australia has been growing genetically-engineered crops for over 15 years, the state of South Australia has banned their use. This moratorium has been in place since 2004, and requires farmers to shift to alternative crop protection strategies that often have a significant yield penalty. Recent changes in political representation in the region appeared to be more farmer friendly, and many felt that change was coming. Unfortunately, local activists connected to Green Party re...

The genomics era has generated tremendous data sets, yet the information they reveal is limited by the human biases that search them. Are there ways to examine complex data sets for hidden patterns that can unearth new perspectives in biology? This is the role of machine learning, and the patterns form the basis of artificial intelligence that then executes new tasks. While these concepts seem difficult to fathom, Dr. Gabe Musso makes them understandable, and describes the ways they may be appli...

There is an unfortunate side to egg production. Only female chickens produce eggs, so layers are selected at hatching. Chicks are sexed with a vent inspection. Females are kept for egg production. Males live a short ride down a conveyor into a chipper, where they are instantly killed. This practice raises ethical and practical questions. Dr. Nigel Urwin and his collaborators devised a way to identify the sex of eggs before hatching, allowing male eggs to be saved for direct consumption or vaccin...

Can we use genetic engineering to help the body’s immune system target cancer cells? This is exactly what happens with CAR-T (chimeric antigen receptor) T-cell therapy. CAR-T cells are T-cells, immune cells of the body that are reprogrammed to identify specific surface signatures that define specific types of cancer cells. It allows these immune agents to seek and destroy cancer cells with great accuracy and with fewer side effects to traditional chemotherapy or radiation. While in their infancy...

Cotton production is massive, but mostly used for fiber. The cotton seed is a tremendous potential resource as it contains high amounts of oil and high-quality protein. However, the seeds are not directly edible by most mammals because they contain a toxic chemical called gossypol. Gossypol is a terpenoid that the plant produces as a natural insecticide. A team led by Dr. Keerti Rathore at Texas A&M University has worked for decades to produce cottonseed without gossypol. The plants have now...

Nitrogen is a reality of growing plants, and must be supplied to maximize crop yields. At the same time our atmosphere is >70% nitrogen that is not usable by plants in its atmospheric form. Humans have devised processes to “fix” nitrogen into plant usable forms, but they require energy and the products need to be transported, both leading to a substantial carbon footprint. A number of microbes naturally fix nitrogen, yet do not form good associations with all plants. Joyn Bio is a collaborati...
