Barnacles are able to attach themselves to almost anything. They are found clinging to the hulls of ships, the sides of rock pools and even to the skin of whales. Just how they stick so steadfastly whilst underwater has remained a biochemical puzzle for scientists for many years. Now researchers have solved this mystery, showing that barnacle glue binds together exactly the same way as human blood does when it clots.

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 '...

Modified ecstasy could one day have a role to play in fighting some blood cancers, according to scientists. Ecstasy is known to kill some cancer cells, but scientists have increased its effectiveness 100-fold, they said in Investigational New Drugs journal. Their early study showed all leukaemia, lymphoma and myeloma cells could be killed in a test tube, but any treatment would be a decade away.
