The magazine Pictures of the Future reports that the company is gradually expanding its energy efficiency program to also include the supplier chain. The EEP for Suppliers (EEP4S) program identifies and evaluates energy-saving potential in production processes and can reduce energy consumption by as much as 17 percent.
Supplier sustainability is also important, however, because Siemens is one of the world’s biggest procurers of products and services: In 2010 the Group made purchases totaling approximately €37 billion in 177 countries. EEP for Suppliers was therefore launched to reduce energy consumption in the supplier chain. Participants can choose between four program variants designed in accordance with the energy intensity of their production processes and their level of production volume. Participants that opt for the most extensive variant are visited for several days by certified Siemens environmental consultants who tour the entire factory, analyze building structures, closely examine the energy consumption of individual units, study manufacturing and maintenance processes, and review procurement contracts.
The consultants then draw up a report in which they present proposals for energy-saving measures, calculate the required investment, and estimate how long it will take for the energy savings to pay for the outlay. The supplier pays the consulting costs. Also available is a free self-assessment tool that allows small companies or plants with less energy-intensive operations to assess their processes and identify savings potential.
Siemens incorporated an initial 160 suppliers with energy-intensive production processes into the EEP4S program in business year 2010 – 2011. A further 840 companies will be added next year. Plans call for EEP4S to become an established part of the Siemens supplier management system over the long term.

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...
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...
