New library of HIV mutants could inform vaccine design

Laboratory manipulation of the AIDS-causing virus reveals evolutionary ‘dead-ends’

June 1, 2017 | By Rachel Tompa / Fred Hutch News Service

Fred Hutch researchers have created a library containing millions of mutant HIV viruses. Some of these mutants are very good at infecting human cells, no different from their “natural” viral ancestor. Some of them are worse. Together, they can teach researchers something important about HIV in humans.

Of mutant flies, tangled sperm and the 'Mother's Curse'

Study in fruit flies identifies a mutation in mitochondria — the energy factories of our cells — that harms males but not females

Aug. 2, 2016 | By Rachel Tompa / Fred Hutch News Service

For the first time, evolutionary biologists at Fred Hutch have identified a "Mother's Curse" mutation - a genetic change harmful to males but not females - in animals. The mutation renders male fruit flies sterile but leaves female flies untouched.
