Maps of burning Spanish forests taken from space have been relayed to local fire fighters in near real-time. A successful demonstration campaign using Earth Observation data has taken place in Galicia – delivery time from raw orbital data to final value-added product in the hands of the user came to 92 minutes.
Around 45 000 forest fires start across Europe every year, with half a million hectares of woodland lost in the Mediterranean region alone. The European Commission estimates the cost of every hectare burnt equals between a thousand and 5000 Euros. Satellite data are used for compiling forest fire risk indices as well as damage mapping, but rapid provision of fine-resolution data has so far not been used in operational fire fighting. To track blazes as they happen, fire fighters must rely on eyewitnesses or helicopter surveys – up until now.
The Galicia-based demonstration campaign is known as DEMOBIRD and commenced with an initial trial on May 30. This involved using infrared sensors aboard Germanys BIRD (Bi-spectral Infrared Detection) satellite to chart thermal hot spots within a 190 km strip of land during the satellites four-minute pass over the Spanish province.
Once the satellite acquired the data it was downlinked to ESAs Villafranca tracking station near Madrid, then transferred to the German Aerospace Centre DLR for calibration and passed on to Spanish prime contractor INSA to be processed for products, delivered to users and validated with GPS readings taken on the ground.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
