Earth has entered the "Anthropocene", a new geological era in which humans rival nature in their impact on the global environment, say scientists speaking at the EuroScience Forum in Stockholm today.
“Mankind’s use of Earth’s resources has grown so much that it seems justified to denominate the past two centuries and into the future as a new geological era,” says Professor Paul Crutzen, the Nobel prize-winning atmospheric chemist who first coined the term.
Speaking at a EuroScience symposium* on the future of the Earth organized by the International Geosphere-Biosphere Programme (www.igbp.kva.se), Professor Crutzen and others point to the dramatic change in human activities, especially since the 1950s. "The increase in human activity since the Second World War - world economy, resource use, telecommunications, transport and global connectivity - has been astounding," notes Dr Will Steffen, IGBP Chief Scientist, "The consequent human imprint on Earth’s environment is now unmistakable."

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
