'People didn't think it could really be done,' Marc Friedländer, an associate professor in molecular biology at Stockholm University, told CBS News.
, a Stockholm University researcher told CBS News. The breakthrough potentially raises hope for the resurrection of animals once thought lost forever.
Dalen and his team were able to sequence RNA molecules from a 130-year-old Tasmanian tiger specimen preserved at room temperature in Sweden's Museum of Natural History. "If you're going to resurrect an extinct animal, then you need to know where the genes are and what they do, and in what tissues they are regulated," Dalen said, explaining the need for knowledge about both DNA and RNA.
Friedländer said that researchers were able to detect a couple new genes that could not have been discovered by DNA itself. Scientists have focused their de-extinction efforts on the Tasmanian tiger as its natural habitat in Tasmania is largely preserved.

As an essential micro-element for plants, iron (Fe) deficiency not only restricts tomato growth, development and fruit quality, but also poses health risks to animals and humans, resulting in human nutritional disorder worldwide.

How a small strand of RNA is key to fighting cancerA team of researchers has shown that a single, small strand of microRNA, or miRNA, known as let-7, governs the ability of T-cells to recognize and remember tumor cells. This cellular memory is the basis for how vaccines work. Boosting cellular memory to recognize tumors could help improve cancer therapies. The research suggests a new strategy for the next generation of cancer-fighting immunotherapies.
