Koala retrovirus leads scientists to discover ‘second immune system’

K

ABC Science, 12/10/2019 The retrovirus spreading through the koala population is bad news. But studies of the koala infection have led scientists to a surprising discovery: a “second immune system” in the species, according to research published on Saturday in the journal Cell. This system, which the researchers think exists in all mammals, has a role fighting off viruses that are in...

How we inherit masculine and feminine behaviours: a new idea about environment and genes

H

The Conversation, August 18, 2017 3.22pm AEST What if thousands of years of gendered environments actually reduced the need to develop genetic mechanisms to ensure gender differences? This is the idea we suggest in our new paper. Advances in evolutionary biology recognise that offspring don’t just inherit genes. They also reliably inherit all kinds of resources: a particular ecology, a nest...
