Recovered RNA has put scientists one step closer to resurrecting the Tasmanian tiger (www.abc.net.au)

It might sound like the plot of Jurassic Park but scientists believe they can revive the extinct thylacine.

Whereas RNA is a single-stranded molecule that carries genetic information it receives from the DNA, putting this information into practice. Daniela Kalthoff, in charge of the mammal collection at the Museum of Natural History, said the idea of possibly resurrecting the Tasmanian tiger was an "exciting idea".

However, Dr Mármol and his colleagues note that their findings hold significance for global initiatives aimed to resurrect extinct species such as the woolly mammoth, as well as for studying pandemic RNA viruses.

This is the best summary I could come up with:

Lead study author Emilio Mármol, a computational biologist at the Centre for Palaeogenetics and SciLifeLab in Sweden, said to truly understand an extinct species, you need to know what the genes are and what they do.

"RNA sequencing gives you a taste of the real biology and metabolism regulation that was happening in the cells and tissues of the Tasmanian tigers before they went extinct," Dr Mármol said.

The research team was able to recover transcriptome of the thylacine's skin and skeletal muscle tissues from a 130-year old desiccated Tasmanian tiger specimen preserved at room temperature.

"RNA has never been extracted and sequenced from an extinct species before," said Love Dalen, a Stockholm University professor of evolutionary genomics who co-led the study.

Excessive hunting, combined with habitat destruction, and introduced disease led to the rapid extinction of the species, according to the National Museum Australia.
