For some reason, pop news became enamored with this paper last month (unfortunately while I was away at a conference): HIV infection en route to endogenization: two cases Inexplicable media frenzy– Scientists find mechanism for spontaneous HIV cure French scientists find genetic mechanism by which two men were spontaneously cured of HIV. HIV discovery offers…

I write about lots of things on ERV, but I didnt anticipate ever getting to the point where I can write new blog posts on new publications by cutting and pasting from old blog posts on old papers… Lots of news outlets have been talking about this new paper: Impact of HLA-driven HIV adaptation on virulence in…

An Evening with Dr. Richard Dawkins

Attention those of you in the Atlanta area! The students in Kennesaw State University Atheists United have invited Richard Dawkins to speak on campus, and they are opening up their event to the public! Tickets are available for purchase HERE!   Im gonna get him to sign our Nightwish poster!!!  

Creationists and Ebola

The title of this article by Answers In Genesis is a good question: Where Did Ebola Come From? *shrug* Look, I love making fun of Creationists, but this is a great question! Ebola is not ‘supposed’ to be a human pathogen. Like many emerging infectious diseases, the natural reservoir for ebola is bats. Specifically, fruit bats.…

Richard Dawkins and Nightwish

October 2012, I got to see Nightwish at a small venue in OKC. 1– This was one of the first nights Floor Jansen was officially the New Singer for Nightwish. She blew me away. 2– This was a *tiny* venue. Nightwish fills huge stadiums and auditoriums all over the world, but OKC? Teeny venue. And that…

“HIV mutates a lot”. People ‘get’ that. Why is HIV hard to stop? Why is HIV hard to treat? “HIV mutates a lot”. But HIV does not mutate willy-nilly. It mutates at an evolutionarily defined rate. The reverse transcriptase enzyme makes mistakes during replication that are beneficial to HIV– creating a diverse population, a quasispecies,…

c0nc0rdance + HIV vs Creationists

Though ERVs are my favorite tool vs Creationists, HIV is a fantastic choice as well. I mean, has anyone seen hide or hair of Behe since 2007? Poor guy. Alas, there are still Creationists out there, so to address some of their ‘concerns’, c0nc0rdance made a couple of vids using his favorite HIV protein, Vpr:

1– Herpes viruses are old. They are ooooooold. Like, hundreds of millions of years old. Specifically, about 400 million years old. 2– Herpes viruses are everywhere. Fish, reptiles, birds, cows, humans, everywhere. And there are lots of different kinds that humans have to deal with– CMV, EBV, HHV-8, VZV, HSV… 3– And, though herpes viruses should…

Via John Wilkins and John Farrell: A Simple Visualization of How Species Evolve This is basically my dissertation, animated. LOL!! What are you looking at? Every pixel in that square is a genetic sequence. Some of those sequences confer a higher fitness advantage (the red colored peaks) or disadvantage (below the plane). The Blue color…

HIV-1s ancestors just got older-er

More HIV news! HIVs ancestor, SIV (simian immunodeficiency virus), has been around a LOT longer than we previously thought. As I have mentioned before, we always assumed retroviruses like HIV, lentiviruses, are evolutionarily ‘young’. They are relatively complex, so probably ‘newish’ in retrovirus-world, but they do not fossilize well (we have found very few lentiviral…
