A two-year-old girl has made an almost complete recovery after spending nearly 20 minutes at the bottom of a pool. Scans showed Oluchi Nwaubani had been starved of oxygen for some 18 minutes - three times longer than the brain can usually survive - in Bromley, London. Despite being warned that even if she were to live she may never walk or talk again, her parents say she can run around and say "what she wants"...

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 '...

Tiny structures found in 3.4bn-year-old sandstones in Western Australia represent some of the oldest, best preserved evidence of life on Earth. Scientists say their analysis of the microfossils clearly shows the organisms were processing sulphur for energy and growth - not oxygen.
