Saving koalas: Gene study promises solution to deadly sex disease

Australia's most famous tree hugger has been ravaged by sexually transmitted disease, attacks from dogs, being hit by cars and habitat loss.

Chlamydia has spread fast in koalas, causing infertility and blindness.

But scientists say decoding the genome should lead to an effective vaccine for the STD.

In fact, researchers say they've been amazed by the information that's been hidden in the marsupial's DNA.

While they didn't find a gene for cuteness, they've worked out how koalas can survive solely on a diet of eucalyptus - which poisons most other creatures that consume it.
Genes that are switched on in the koala's "cast-iron livers" appear to be responsible for the ability to detoxify the leaves.
