DNA and the Dead Sea Scrolls

We went on an excursion last weekend to see the Dead Sea Scrolls at the Pacific Science Center. None of us could resist going downtown to look at written texts over 2000 years old. Uncovered in 1946, by a Bedouin...

White people are mutants

Razib inspired me to share some of the story behind why white people are considered derivatives. Reposted from the Classic Digital Bio. No red herrings, here! Lamason et. al. found a single gene that controls human skin color while studying...

Using HIV to prove some points about evolution, part IV

Did HIV become resistant to Atazanavir because of a genetic change? Was that genetic change inherited? Did HIV evolve? Can we explain why genetic changes at specific sites might help HIV escape the effects of the drug? Let's find out....

Using HIV to prove some points about evolution, part III

In which we see the results and come to our own conclusions. If you want to let other people tell you what's right and what's wrong, they will surely do so. Turn on the TV and hordes of happy actors...

Waxing lyrical about that stuff in our ears

It's hard sometimes when you're out of synch with the rest of the world. While my fellow ScienceBloggers have been obsessing about breasts, I've been really amused by the genetics of ear wax. Eh, what's that you say? Yes, it's...

Digital Biology Friday: That was no ape, that was my brother!

We've had a good time in the past few last weeks, identifying unknown sequences and learning our way around a GenBank nucleotide record. To some people, it seems that this is all there is to doing digital biology. They would,...

Hello Kitty! or Don't Eat Me, I Study Genetics!

Genetics textbooks abound with stories of European royalty and the hazards of having children after you've married one of your cousins. It struck me as an interesting parallel that the lion is such a popular symbol in so many royal...
