RNA and DNA extraction kits take formalin-fixed tissue samples by storm, enabling superior quality and yields. Researchers using standard extraction protocols that heat samples to eliminate ...

To obtain high-quality, purified nucleic acids, scientists can use several different methods, including phenol-chloroform extraction, cesium chloride/ethidium bromide (CsCl/EtBr) gradient ...

Almost 40,000 years ago, a juvenile woolly mammoth died in modern-day Siberia. Today, its long-frozen remains have yielded the oldest sequences of RNA—messenger molecules that carry out genetic ...

The woolly mammoth is probably the single most iconic extinct mammal, leading to seemingly never-ending efforts to resurrect it. To do that, however, scientists will need a good understanding of their ...

Sept 19 (Reuters) - The Tasmanian tiger, a dog-sized striped carnivorous marsupial also called the thylacine, once roamed the Australian continent and adjacent islands, an apex predator that hunted ...

RNA taken from the desiccated remains of a thylacine, or Tasmanian tiger, could yield a new understanding of the species, which was declared extinct over 40 years ago. This is the first time RNA has ...

There are plenty of unanswered questions about the origin of life on Earth. But the research community has largely reached consensus that one of the key steps was the emergence of an RNA molecule that ...
