CNN, Updated November 8, 2019 For the first time in 19 years, a team of scientists has detected a new strain of HIV. The strain is a part of the Group M version of HIV-1, the same family of virus subtypes to blame for the global HIV pandemic. The findings were published Wednesday in the Journal of Acquired Immune Deficiency Syndromes. HIV has several different subtypes or strains, and like other...
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...
How HIV Possibly Jumped From Monkey To Man
Asian Scientist, April 12, 2018
Scientists in Japan have discovered a protein that may have enabled the simian immunodeficiency virus (SIV) to be transmitted to humans. Their findings are published in Cell Host & Microbe. The human immunodeficiency virus (HIV) is believed to have evolved from a SIV that originated in chimpanzees.

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...
Is monogamy unnatural?
ABC Science Show, Saturday 28 June 2014 12:05PM
Christopher Ryan reviews the enjoyment of sex, evidence from prehistory, and even the charming behaviour of bonobos, to suggest that conventional monogamy is but a blip in human history, and basically, doesn’t work.

Born this way? An evolutionary view of ‘gay genes’
The Conversation, 2 June 2014, 2.17pm AEST
The claim that homosexual men share a “gay gene” created a furore in the 1990s. But new research two decades on supports this claim – and adds another candidate gene.
