Recent evidence suggests that a non-pigmentation mutation of the epidermal structural protein filaggrin (FLG) better explains how populations in northern latitudes, namely northern Europeans, compensate for lower levels of ultraviolet-B light exposure (1). Scientists from the University of San Francisco compiled loss-of-function FLG mutation prevalence data from various populations and...

A Semi-Synthetic Organism: The Third DNA Base Pair?

The Romesberg team at The Scripps Research Institute (TSRI) recently created an unnatural DNA base pair that can be incorporated into the genome of E. coli. While in nature the genetic code only contains two DNA base pairs, A-T and C-G, these researchers have made a bacterium that can “stably...
