As part of this effort, the global Siemens research organization Corporate Technology has become the technical coordinator of the EU’s FINSENY (Future INternet for Smart ENergY) project, in which energy and communications technology experts are examining what demands smart grids are likely to make on tomorrow’s Internet. One aim is to provide operators of low- and medium-voltage grids access to inexpensive and reliable communications networks and technologies — a key requirement if renewables are to play a more important role in the power mix. The first pilot applications are scheduled to be set up in 2013.
Because it is inexpensive and available in many places worldwide, the Internet is an ideal network not only for normal telecommunications but also for many industrial applications. However, the Internet standards, which in some cases are 40 years old, are often inadequate from a technological standpoint.
Smart grids are one example of a new area of application. Here, power networks are to ensure a stable and affordable energy supply. A sustainable, state-of-the-art power grid with many independent, widely distributed producers of renewable energy can only perform such a task if all of the participants are optimally coordinated with one another. When the sun is shining, for example, the system would use solar energy to charge the batteries of electric cars. It’s therefore essential that the communications medium is reliable. In today’s smart grids, the power lines themselves are often used to transmit control data for low- and medium-voltage systems. However, power lines are not suitable for transmitting large amounts of data over long distances. Communication through the current Internet would not be a satisfactory solution either, since some of the existing technology does not guarantee high enough levels of reliability or security. For example, when the grid load is high, the transmission of control information could be delayed or lost. Another difficulty is that today’s Internet protocols are not capable of providing adequate security against hackers’ attacks on the electricity supply.
Industrial organizations that address issues related to smart grids and/or smart energy can actively support the FINSENY project by becoming members of the Smart Grid Stakeholder Group.

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...
