COVID-19: The Evidence for Aerosol Transmission & Implications for Containment

This week How on Earth producer Beth Bennett spoke with Professor Jose Jimenez, a professor in the Chemistry Dept here at CU in Boulder. His research background for over two decades has focused on detecting and measuring aerosols. Recently he became involved in applying this expertise to the question of how the corona virus is transmitted. He and his team have developed a model that predicts the likelihood of transmission of the virus from an infected person to other people in an indoor space. Here are find links to the model, a webinar describing its development and use and his website. The interview starts at ~8 min.

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.

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.

Corona Virus: Therapies and Transmission

nCoV-1This week on How on Earth, we are still producing off site. Beth and Angele give an update on treatment and transmission of the corona virus and Shelley interviews CU Boulder scientists Anushree Chatterjee and Prashant Nagpal who explain the pros and cons of using old medicines to fight Covid-19, and they describe some new “medicines” in the future, and how to speed up their development.

CoVid19 Update // Beer Chemistry Redux

This week How on Earth adjusts to the restrictions imposed by the corona virus by replaying a previous feature on the chemistry of beer brewing. First Beth gives an overview of some proposed treatments for corona virus. Then, the featured interview with author Pete Brown. When the New York Times reviewed Miracle Brew, the reviewer said: A magisterial tour of fearsome science and vast brewery history leavened with cheery anecdotes, humor, vivid you-are-there prose and a clever eye for personality . . . His rhapsodies about the meaning of life and the meaning of beer are stirring. . . .His expertise and insight will leave you with a glimmer of infinity every time you hold a bottle of it in your hand.

COVID-19: ACE, Targeted Therapies, Old & New Medicines

Antimicrobial Regeneration Consortium LogoThis episode talks about research about COVID-19, angiotensin converting enzyme (ACE), and targeted therapies, and our feature is an interview with CU-Boulder scientists Anushree Chatterjee and Prashant Nagpal. This husband and wife science team explains why there may be a downside to adapting old medications to fight Covid-19.  They’ll also explain their anguish about why creating new “drugs” to fight Covid-19 cannot happen as fast as they or anyone would like.  They have founded the Antimicrobial REgeneration Consortium, with the goal of speeding up the creation and availability of antimicrobial medicines.  They are also developing a way to give people a tiny dose of nanoparticles–basically incredibly tiny microchips, preprogrammed to specifically target a disease such as Covid-19  (see our earlier discussions with them).
