Koala retrovirus leads scientists to discover ‘second immune system’

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 the same class as deadly human diseases such as HIV. This “second immune system” may illuminate new ways to treat HIV, said Damian Purcell, who heads up virology research at the Doherty Institute for Infection and Immunity.

No single ‘gay gene’, reveals the largest-ever study of the genetics of same-sex sexual behaviour

ABC news, 30/08/2019

Scientists have again debunked the idea of a single “gay gene”, in the largest study to date of the genetics of same-sex sexual behaviour.

Rather, their findings paint a diverse and complex picture of human sexuality, and the genetic factors that influence it.

Nearly half a million people took part in the study, mostly from the United Kingdom and the United States, which was published in the journal Science today.

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.

Should Doctors Operate On Intersex Babies?

Buzzfeed,

M.C. was born with ambiguous genitalia, a rare condition that doctors addressed with surgery. Now, in a landmark lawsuit, M.C.’s parents are challenging the medical mainstream: Why does a surgeon decide what sex a child should be?
