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.

Scientists say they have made a synthetic blood-clotting agent that could help wounded troops and patients.

The test identifies tumour DNA "rearrangements" which are specific to the individual patient. In the future, this "genetic fingerprint" could be used to pick out tiny remnants of a tumour. ... Such techniques are currently very expensive but costs are falling.

It's perhaps the most controversial religious artefact in the world. The Shroud of Turin cloth that supposedly wrapped Jesus's body after the crucifixion and became imprinted with his image, has intrigued millions of believers and sceptics alike.

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 '...

The 'white-coat' effect - where blood pressure rises during a check by a doctor - is even worse in someone whose level is already high, researchers say.

Scientists have developed a technique to estimate the age of a suspect from blood left at a crime scene.
