Our stunning cover picture gives a clue to one W of our top stories – in fact a top story for NERC this year. It’s not a poster for a new Cunard liner but a pre- launch shot of our equally stunning research ship – the new RRS Discovery. Discovery has been years in the making and represents a significant capital investment in UK environmental science. She’s a fine example of cutting-edge engineering meeting cutting-edge research facilities and is robust enough to take marine scientists into some of the most hostile seas on the planet. The ship can accommodate researchers across a range of disciplines; together they will bring back new understanding of our enigmatic oceans – how they support marine ecosystems, regulate our climate and ultimately ERC has joined forces with the US’s National Science maintain life on Earth.

The fruits of their labours are now available at www.3d-fossils.ac.uk. There are thousands of high-resolution photos, 3d models and stereoscopic images of the fossils – the database isn’t fully populated yet and scanning work continues, but more information is being added all the time. Also included is comprehensive data about each one – where it was found, what species it comes from, its place in the tree of life, and even the paper in which it was first described. The 3d models are particularly innovative. The files can be downloaded and read using open-source modelling software, and they’ll work with 3d printers – the revolutionary technology that lets computers create real, physical objects by building up layer upon layer of plastic. Until recently these cost so much they were out of reach for almost everyone, but prices have plummeted in recent years. It may not be long before they are within the budget of the average school, and students will be able to handle exact replicas of some of the most important fossils ever discovered and find out about how they were found and what they tell us about the story of life. BGS is collaborating on the project with the Natural History Museum, the Sedgwick Museum of Earth Sciences, the Oxford University Museum of Natural History, the National Museum Wales and the Geological Curators’ Group. Funding came from Jisc, the public body that supports the use of IT to improve education.
