Natural Prodcast is a podcast about natural products and the science and scientists of secondary metabolism. Natural products, secondary metabolites, specialized metabolites -- whatever you want to call them, they're the chemicals that make species unique and different from one another, and are incredibly important to medicine, the environment, and human health. Hosts Dan Udwary and Jackie Winter introduce concepts in this exciting field, and talk to the fascinating scientists who work in it ...

Stable Isotope Probing (SIP) is a powerful technique for studying microbial communities. These experiments can show which microbes are handling specific nutrients, or what they're doing with those nutrients, and even how quickly. But there's a catch: SIP labwork and analysis can be very demanding. The JGI offers SIP analysis to make these experimen…

In our warming world, we’ll need corn, sorghum and other crops to grow well in worse conditions: with more heat, less water and less fertilizer. Grasses do better in these conditions, so plant biologists James Schable, Guangchao Sun and Vladimir Torrres have looked into traits that could transfer from grasses into other crops. One grass they studie…

Every year, the JGI sequences around 35,000 samples — from plants, algae, bacteria, archaea, fungi, viruses — to support scientists around the world. Most of those researchers send their samples in from afar, without ever hearing much about the sequencing lab. So today, Chris Daum walks through the JGI’s sequencing pipeline, where there are freezer…

We count on livestock for food and fiber, but raising these animals also produces an atmosphere-warming gas: methane. Those emissions mainly come from gut microbes — the bacteria and archaea breaking down plant matter. So since 2010, the JGI has supported researchers studying those microbial methane-makers. Eventually, that could help us dial back …
