New Method for Measuring CO2 from Fossil Fuels

smokestackThis 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 website and read his recent paper published two weeks ago in PNAS.

In this episode Angele Sjong interviews Tyler Lyson, a vertebrate paleontologist at the Denver Museum of Nature and Science, about his team’s extraordinary fossil discovery at the Corral Bluffs.

When the asteroid destroyed most of life on earth 66 million years ago, including the dinosaurs, this cataclysmic event ended the Age of Reptiles and began the Age of Mammals.Paleontologists have long struggled to understand the first million years of the Age of Mammals, however.  What kinds of mammals survived this event?   When and how did mammals become big again?  When did mammals begin to diversify?  What was the plant life and climate like at this time?   The animal and plant fossils at Corral Bluffs shed light on this critical time period in earth’s history that has been a mystery for so long.

The Nature of Science // Biology is Everywhere!

898e6e_a2796ccdceee4c5fbe8120db2def5fee~mv2Today on How on Earth, Beth plays part of a 1964 lecture by Nobel laureate Richard Feynman in which he discusses how the scientific method actually works and the progressive, and therefore uncertain, nature of science. Then she speaks with Dr Melanie Peffer about her book, Biology is Everywhere, and her goals of making biology accessible and interesting to everyone. Her website was cited incorrectly on the show, here is the true link.

Do Masks Protect from Corona Virus // AgriSolar in Boulder

55519534_321133708588329_7989546873243303936_nBeth and Angele discuss the pros and cons of mask wearing as protection against the novel corona virus. You can see the video on sneezing, as well as the various types of masks. Then, Angele talks to Byron Kamenick from Jack’s Solar Garden, located outside of Niwot. Jack’s Solar garden is putting in place an Agrivoltaics system this summer. Agrivoltaics combines agriculture and solar panels (photo-voltaics). There are mutual benefits to locating these together. You can find out more about Jack’s at their website.

Antibody Testing // Why is the FDA Cracking Down on Raw Milk Cheese?

contentThis week on How on Earth, we speak with Professor Catherine Donnelly, of the University of Vermont, about her book, Ending the War on Artisan Cheese. She exposes the efforts of the corporate dairy industry, in conjunction with the FDA, to limit the use of raw milk in making artisanal cheese, despite a long track record of safety in artisans cheese. in this fascinating book, she discusses the art of cheese making, and the self-imposed guidelines that make using raw milk in the artisanal process safe.
