More security in public spaces without forfeiting privacy or personal rights. The Fraunhofer Institute for Open Communication Systems (FOKUS) exhibits at the CeBIT 2014 (Hall 9, Stall E40), that this need not be contradictory. The crisis management system SAFEST with the help of infrared cameras, recognizes critical situations in crowds and guides people in danger away from the dangerous zone. In doing so neither movement profiles nor personal data is recorded.
The Smart-City-Institute FOKUS with the joint project SAFEST (Social-Area Framework for Early Security Triggers at Airports) will show at this year’s CeBIT,...06.03.2014 | Read more
Big Data is one of the key research and strategy topics for the world of business. Now 24 Fraunhofer Institutes have come together to pool their expertise in the new Big Data Alliance, creating a single point of contact for companies, politicians and researchers. The alliance will make its debut appearance at CeBIT 2014 (Hall 9, Booth E40).
There were some two sextillion bytes of data stored worldwide last year. Being able to efficiently analyze and structure the ubiquitous flood of data allows us...05.03.2014 | Read more
Exams are approaching, and stress is increasing. Now it’s just about memorizing material – things that will almost entirely be forgotten again shortly afterwards. But does it have to be this way? The answer is no! Fraunhofer IDMT has developed ”askMe!”, a system for personalized computer based assessment of one’s learning results. The system will now be presented at the CeBIT, taking place March 10 - 14 in Hanover.
”askMe!” allows students to apply the theoretical knowledge they have acquired to practical situations, and to transfer this knowledge to other areas of...03.03.2014 | Read more
At the upcoming CeBIT in Hannover (10.-14.3.2014) the German Software-Cluster shows its latest research results and start-ups from the cluster region spanning the German states of Baden-Württemberg, Hesse, Rhineland-Palatinate and Saarland. The connecting theme of the exhibits is making business processes faster and more dynamic, e.g. in the retail, mobility or agriculture sector.
Processes are at the core of the economy. The German Software-Cluster, distinguished in the leading-edge cluster competition of the German government,...28.02.2014 | Read more
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...
Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
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...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
