Higher viral load during HIV infection can shape viral evolution

A new paper in Molecular Biology and Evolution finds that HIV populations in people with higher viral loads also have higher rates of viral recombination. In effect, the more HIV in the blood, the easier it is for the virus ...

Genetics

Human egg cells are imperfect surprisingly often

More than 7% of human oocytes contain at least one exchangeless chromosome pair, demonstrating a remarkably high level of meiotic recombination failure, finds a study appearing December 10 in the American Journal of Human ...

Bat cave study sheds new light on origin of SARS virus

Genetic recombination between viral strains in bats may have produced the direct evolutionary ancestor of the strain that caused a deadly outbreak of severe acute respiratory syndrome (SARS) in humans, according to new research ...

Engineered flies spill secret of seizures

In a newly reported set of experiments that show the value of a particularly precise but difficult genetic engineering technique, researchers at Brown University and the University of California–Irvine have created a Drosophila ...
