Microbes are everywhere, including inside our pets! This week, Ben Alverson comes on to give us a crash course in veterinary parasitology. He discusses the variety of worms and protists that can live inside mammals and cause problems ranging from being a mild nuisance to causing death. We talk about the different types of animals that get tested for these parasites including cats and dogs, zoo animals like big cats, and farm animals. Ben does a great job explaining how diagnoses are made from examining poop samples, what that process looks like, how identifications of different eggs and and parasites are made using microscopy, and treatment options. This episode showcases a non-academic career path in microbiology that's absolutely fascinating! (But it is not for the squeamish!)

Ben Alverson is a microbiologist with experience in the veterinary field. He runs the brilliant Instagram account @veterinary_parasitology_ where he posts photos of ova (eggs) and parasites found in his work. I HIGHLY recommend following him! You can also find him on Twitter.

American science has been under attack since this Trump administration began. Tens of thousands of scientists and federal workers have lost their jobs and the effects are starting to permeate through society. This week I have Dr. Kevin Bird on to explain the events of the last 3 months, how science is funded in the United States, why it is being attacked so aggressively, and the ideologies behind these attacks. He also gives us a history lesson on movements of the past that sought to protect the scientific enterprise. It is really important to protect science. Publicly-funded research benefits us all! (Also, sorry for the choppy editing on this episode; I wanted to get this one out quickly!)

Kevin is a NSF Plant Genome Postdoctoral Research Fellow at UC Davis studying the evolutionary impact of structural variation in plant genomes. He also researches scientific racism and posts lots of interesting stuff on his Bluesky account. You can also learn more about his work on his website or Google Scholar page.

Here are some articles Kevin recommends:

1. Brand new article about the NSF freeze
2. Article about the impacts on US science
3. Article about US brain drain
4. USDA and food security
5. US-AID labs that were cut
6. Article on the admin’s resegregationism and Project 2025
7. Article about TESCREAL
8. Article about neoreaction
9. Radical science movements from the past

If you tuned in last week, you'll know that diatoms produce one quarter of the air we breathe (and they produced this podcast's logo), but did you know that they can also be used to solve crimes???! Rather than spoiling too much by writing a long caption here, you should just press play to hear from Dr. Kirstie Scott, a forensic diatomist and one of the most interesting people I've spoken with. In this episode we discuss how certain environments have certain cells and how these cells can travel on clothes and in bodies. We also talk about different types of evidence, testifying in court, and many ways in which trace signatures of organisms in the environment can be used in to answer diverse research questions. If you like Dexter or Bones or true crime, this episode is for you!

Kirstie is a senior lecturer in forensic bioscience at Liverpool John Moores University in the UK where she specializes in diatom analysis. You can find her on Linkedin, Google Scholar, X, and Bluesky.

Here are some resources Kirstie recommends:

1. How microscopic algae are helping forensic teams catch criminals
2. Research article on marine diatoms as trace evidence indicators
3. Dead bodies can reveal details of their death through microscopic diatoms
