Because he wants to study HIV, for his birthday last year I went to Giant Microbes.com and sent him his very own HIV virion:
But the best part was pointing out that because it was me sending it to him, technically it counted as maternal transmission.
The first month, he worked in a lab studying a virus that infects certain insects, which allowed me to quip:
“Ah: bug bugs.”
This month he is studying SIV, simian immunodeficiency virus, the monkey version of AIDS. It’s all bench work, studying molecular mechanisms; he’s not working with actual animals at all. My response:
“I see; just Rhesus pieces.”
