Until recently, it was a commonly held belief among HIV-1 researchers that the virus evolves at a relatively slow pace during early infection. But a new computer simulation that reconstructs the speed of HIV-1 protein region evolution from a single virus has challenged that notion. The University of Adelaide's Jack Da Silva published a paper in the March issue of Genetics that described this new computational method. It simulates population changes due to the killing of infected cells by the immune system, together with recombination and random genetic changes.

Though many details have yet to be worked out, the draft deal for the UK's withdrawal from the EU is giving researchers some hints for what they can expect, Nature News says.

DNA testing has solved a 100-year-old mystery contained in the skull and teeth samples of a now-extinct monkey that once inhabited Jamaica, Gizmodo reports.

As the UN ponders a ban on gene drives, one malaria researcher says there are less dramatic ways to fight the disease in Africa than unleashing GM mosquitoes on a whole continent.
