A pair of German satellites flying in formation has completed the most detailed 3-D map of the land surface of the Earth ever made. Luis Gomes of Surrey Satellite Technology Ltd and Prof Philippa Berry of De Montfort University in Leicester discuss the satellite radar technology used to create such maps and their applications, particularly for predicting the consequences of floods and other natural disasters.

The Lost Fossils of Darwin's Friends

Thin sections of plant fossils from the newly rediscovered collection including the 300 million-year-old cones of giant club moss trees from the Midlands and a sample of fossil wood collected in Chile by Darwin during the voyage of the Beagle. Photos: British Geological Survey.

While searching through the vaults of the British Geological Survey, palaeontologist Howard Falcon Lang of Royal Holloway University of London came across a cabinet labelled unclassified plant fossils. It contained microscope thin sections and almost the first he looked at had a name on it: Mr C Darwin. It turns out to be a collection of fossils brought together by Darwin's friend Joseph Hooker in the mid 19th century and subsequently forgotten.
