Tasmanian devils are evolving to resist a deadly cancer
They are an iconic symbol of Australian wildlife that found fame as a frenetic cartoon character.But in just two decades numbers of the ferocious Tasmanian devil have plummeted by around 85 per cent.The muscular carnivorous marsupials have been devastated by a strange infectious cancer that has spread rapidly through their populations on the island.But a new study has found Tasmanian devils are rapidly evolving resistance to the disease that could save them from dying out.

Tasmanian devils are rapidly evolving resistance to deadly cancer
A transmissible cancer — the devil facial tumor disease (DFTD) — has decimated Tasmanian devil populations.The contagious cancer, first recorded in 1996, has wiped out over 90 percent of these animals in some parts of Tasmania.The disease kills virtually every devil it infects, but there may be some hope, researchers have found.A new study published in Nature Communications suggests that Tasmanian devils are rapidly evolving resistance to fight the cancer, and may be able to escape extinction.

Tasmanian devils are a tenacious mammalian species, the largest carnivorous marsupial left on Earth.They've managed to eek out an existence on the Australian island of Tasmania, where they've remained relatively sheltered from threats that have wiped out other marsupial species throughout the rest of the Australian continent.But now there's a new threat that many researchers fear could be the beginning of the end for this charismatic species: a highly contagious form of facial cancer that was fatal to nearly 100 percent of all devils that caught it when it was first detected in 1996.There's good news, though.

Healthy Tasmanian devils released to test efficacy of contagious cancer vaccineUpdatedThirty-three healthy Tasmanian devils have been released into the wild in the state's north to trial a vaccine against a contagious cancer.Researchers have been developing a vaccine against the devil facial tumour disease, which has wiped out more than 80 per cent of the population since it emerged 20 years ago.The devils released last night were immunised, and will interact with the wild, diseased population at the Stony Head military training area.Save the Tasmanian Devil program manager Dr David Pemberton admitted it was a risk to mix healthy devils with the native population but said it was the next step.

Tasmanian devils are adapting to their gnarly face cancer
For years, Tasmanian devils have been ravaged by gnarly facial tumors, cutting their numbers and pushing them toward extinction — but a new study suggests they may pull through after all.Scientists at the University of Tasmania have been collecting genetic samples from the devils since before the cancer started spreading.That let an international team of researchers analyze genetic changes — which showed that these bad-tempered teddy bears are evolving in response to the disease, according a report in the journal Nature Communications.Tasmanian devils are known for their love nipsThe problem with the facial tumors is that they're contagious — and Tasmanian devils are known for their love nips.
