The scientists in the film Jurassic Park reconstructed dinosaurs from DNA preserved in amber. That fiction is unlikely ever to become fact because DNA simply is not tough enough to survive in that way. But reconstructing a dinosaur from genes passed down the evolutionary tree to modern birds might be viable...

The approach is - with current technology - the only way to picture what ancient DNA code might look like. Biological molecules break down very rapidly after an organism dies and researchers would be extremely lucky to find long segments of coherent code surviving in cells beyond a few thousand years. ... Scientists have also identified the smallest number of genes required to sustain life in a bacterial cell (about 350). If they can...

The researchers sequenced haemoglobin genes from the DNA of three Siberian mammoths, tens of thousands of years old, which were preserved in the permafrost. The mammoth DNA sequences were converted into RNA (a molecule similar to DNA which is central to the production of proteins) and inserted into E. coli bacteria. The bacteria faithfully manufactured the mammoth protein. The resulting haemoglobin molecules are no different than '...

A new study of a 150-million-year-old fossil of an Archaeopteryx has shown that remnants of its feathers have been preserved.

Thanks to a set of new tricks and tools, modifying animals is becoming a lot easier and more precise. That is not only going to transform research, it could also transform the meat and eggs you eat and the milk you drink.

Virgin births do occur among animals. Many invertebrates, such as insects, can produce offspring asexually, without ever having mated. They usually do this by cloning themselves, producing genetically identical offspring. But among vertebrate animals, it remains a novelty, having been documented among less than 0.1% of vertebrate species.
