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

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, parents and peers. And it appears that these stable environmental factors can help ensure the reliable reproduction of a trait across generations.

Studies look at brain and cognitive changes in people with HIV as they age

People with HIV often show persistent signs of cognitive impairment and abnormalities in brain structure despite suppressive antiretroviral therapy (ART), but they do not appear to experience accelerated decline compared to HIV-negative people as they age, according to research presented at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI) last month in Seattle.
