Tiny traces of DNA found in cave dust may unlock secret life of Neanderthals, solving the mystery of early man. Scientists have pinpointed major changes in Europe’s Neanderthal populations - from traces of blood and excrement they left behind in a Spanish cave 100,000 years ago.The discovery is the first important demonstration of a powerful new technique that allows researchers to study DNA recovered from cave sediments. No fossils or stone tools are needed for such studies. Instead, the good news is that minuscule traces of genetic material that have accumulated in the dust of a cavern floor can be employed to reveal ancient secrets.

JCB digs up a green future with hydrogen engines. Chairman, Lord Bamford, believes hydrogen is at risk of being overlooked in the rush to go electric.

Its task is not so much to dig but to try out JCB’s latest effort to help save the planet - and the combustion engine. Powering the machine is a new hydrogen engine developed by the company, which it predicts could be a better alternative to diesel than electric batteries or hydrogen fuel cells for much of its heavy construction machinery.
