Australians can now have their say on the issues around mitochondrial donation.
Should Australia allow the creation of babies with DNA from more than two people? This reproductive technology could prevent babies being born with mitochondrial disease, so the simple answer is yes.
What happened to make plague able to cause devastating epidemics, as in this depiction from 1349?

People caught and died from plague long before it caused major epidemics like the Black Death in the middle ages. Could what scientists call cultural resistance be what kept the disease under control?
A study claims the first humans lived in a wetland around what is now northern Botswana.
It's likely our species doesn't actually have a single origin.
The talamanca hummingbird, or admirable hummingbird, is found in Costa Rica and Panama.
How many genes do you really need? Are there any that we can lose? Researchers are now identifying species that have streamlined their genome to adapt to a particular lifestyle.

People who moved away from Britain's coal-mining areas have genetic profiles linked to higher educational attainment and better health than those who stayed.

It is essential that scientists seek to understand the unique experiences of individuals with schizophrenia.
CRISPR has many applications, including targeted gene therapy, but the precision of the technology still has a way to go.
CRISPR technology is continually improving to make it more specific, but serious consideration should be given to when and how CRISPR is safe for gene editing.
Having a hallucination or delusion doesn’t necessarily mean you have a mental health condition, such as schizophrenia.

As many as one in ten people will have a psychotic experience in their lifetime – and researchers now know your genes play a role.
Dugongs are rare and elusive.
While the other members of the Sirenia are found in the Atlantic, the dugong is the only sea cow found in the Indian Ocean and south-western Pacific. This highlights its deep African connections.
Bill Maher suggests that fat-shaming may help people lose weight.
Fat-shaming is as ineffective as it is cruel. The bullying tactic also ignores the biological factors underlying obesity, which are not always under a person's control.
Identical twins look the same, are the same sex, share the same birthday and shares the same genes.
Interestingly, there are more non-identical twins in Australia now than there have been before. The number of twin pregnancies has grown over the past 30 years.

A thought experiment from Richard Dawkins' book The Selfish Gene turned out to be a more realistic explanation for altruism than he expected.
More than 200 gene variants have been linked to outstanding sporting performance and this number could increase as we continue to research the link between genetics and athlete performance.
Genetic testing could help us build targeted and effective training routines for athletes, but the emerging science could also introduce opportunity for discrimination in the sporting world.
The biology of same-sex attraction seems to involve a host of genes.
The largest study of its kind - comparing the genetic sequences of almost half a million people - has revealed many different parts of our genetic code that seem to influence same-sex sexual behaviour.
It seems genes have a greater influence than previously thought not only on the number of moles you have but also where they are on your body.
Changes in our environment can reveal previously hidden mutations in our DNA with potentially good and bad consequences.
Outside Earth’s protective atmosphere, there is nothing to shield astronauts from the dangerous cosmic radiation of space.
Space missions are dangerous. But when it comes to long missions, radiation may be the greatest threat to astronauts' health.
The ancestral population of modern humans appears to have split as it moved across Asia.
New research outlines how the ancestors of modern humans interbred with several archaic human groups on the passage from Africa to Australia.
What a good boy.
Having different coloured eyes is quite unusual, but it happens in many species throughout the animal kingdom.

New study challenges traditional view of Parkinson's disease.
