Salmonella Biofilms — Inside of Us. (starts 4:06) Foodborne Salmonella infections MIGHT pave the way for arthritis, Parkinson’s disease and even Alzheimer’s. We talk with Aaron White, co-author of a new study documenting how a salmonella infection can “leak” out of the intestines and form velcro-like biofilms in body tissues. These biofilms are made of curly-shaped, curli (scientific name) proteins on the surface of a Salmonella bacteria. These curli proteins help the cells stick together. They’re hard for the body to scrub away, and they might contribute to a number of health problems. (GO HERE for Extended Version TRANSCRIPT with links to related research)

This week on How on Earth, Beth interviewed Scott Lehman of the University of Colorado here in Boulder. Dr Lehman collaborated with a team at NOAA, to develop a novel technique to identify the CO2 released by burning of fossil fuels, allowing its exact calibration in the global carbon budget. Due to technical difficulties, you can’t hear Beth’s questions in the audio, but Scott’s responses are very clear. You can find more information at his
