Today’s episode is just a brief update on Episode 19 with new work published on microbes discovered on the International Space Station.

Here’s a link to the published work:

Methylobacterium ajmalii sp. nov., Isolated From the International Space Station

This week’s episode gives a general overview of the biological research ongoing at NASA Science.

Here’s a link to the Space Biology program at NASA Science.

This is the paper discussed in this podcast:
Counteracting Muscle Atrophy on Earth and in Space via Nanofluidics Delivery of Formoterol

This week’s episode discusses the impact of animal agriculture on the environment, what a plant-only agriculture system would look like, and some strategies for reducing methane emissions by cattle.

Here are the papers I discuss in this episode:

1. Nutritional and greenhouse gas impacts of removing animals from US agriculture
2. Inclusion of Asparagopsis armata in lactating dairy cows’ diet reduces enteric methane emission by over 50 percent
3. A heritable subset of the core rumen microbiome dictates dairy cow productivity and emissions

New Year, New Episodes!

This first episode of 2021 discusses GalSafe Pigs which were recently approved by the FDA for human consumption and biomedical use.

The following are the papers I discuss in the episode:
1. Targeted disruption of the α1,3-galactosyltransferase gene in cloned pigs
2. Production of alpha 1,3-galactosyltransferase-deficient pigs

I’m finally back with a new episode! This episode focuses on the Southern White Rhino, and how captive diets are impairing their reproductive success.

Here’s a link to the paper I discuss:

This week’s episode talks about the hunting strategies of Great White Sharks, and how they relate to their energetics. Turns out, they’re kind of lazy hunters…check it out here!

Here are the links to the papers I mention:

This week, I’m discussing the history of cloning, along with its current applications. Check it out!

Here are a couple links related to the work I discuss:

This week I’m discussing my most recently published article! This is work that I did at Virginia Tech with dairy heifers, looking at the effects of supplemental post-absorptive propionate on energy metabolism and reproductive performance.
