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.
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?
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.
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.
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.
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.
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.
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 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.
