Science Friday: Evolution of an illness: viruses may target men and women differently | Researchers uncover why morning people should not work at night

Posted on 13/12/2016

New research from Royal Holloway, University of London, published today in Nature Communications, has shown that viral infections can evolve to affect men and women differently and become more virulent in men. Particularly if the virus is transmitted from mother to child, women are more valuable to the virus than men are.

Researchers from the School of Biological Sciences at Royal Holloway looked at the virus HTLV-1, which can cause leukaemia in infected individuals. Infected women tend to develop leukaemia less often than men when there is more mother-to-child transmission. Mortality due to infectious diseases is often higher men than women, but this has historically been attributed to differences in the immune system of each sex.

It has been known for a long time that early risers work less efficiently at night than night owls do. But researchers have uncovered new and distinctive features between the night activities of these two types of individuals. At night, early risers demonstrate a quicker reaction time when solving unusual attention-related tasks than night owls, but these early risers make more mistakes along the way.
