The International Committee for Future Accelerators (ICFA) announced at a scientific conference in Beijing that the planned International Linear Collider (ILC) is to be realized in superconducting technology. This decision is of great importance for DESY and its international partners, since they developed this technology together and successfully tested it at the TESLA Test Facility (TTF) in Hamburg. The ILC is the next major project of particle physics. No decision has yet been taken on the realization and site of the facility. As the next step, particle physicists will now join forces to develop the technical design of the project as rapidly as possible.
The ICFA committee, which represents particle physicists worldwide, thus decided between two possible technologies that have been developed in America, Asia and Europe during the past 12 years. The two technologies differ mainly in their accelerating structures, the so-called cavities. These accelerate the particles to high energies before they collide. The cavities can be normal conducting and are then operated at room temperature (“warm” version), or superconducting with an operating temperature close to absolute zero (“cold” version).
“With this technology decision, worldwide particle physics has made a major step forward toward the future – a step in which the true success really is the international agreement,” commented Albrecht Wagner, Chairman of the DESY Directorate, today at a press conference of the International Institute of High Energy Physics (IHEP) in Beijing. “Without the worldwide endorsement of one of the two viable technologies, realization of the ILC project would be unthinkable. Of course, DESY takes note of the technology decision with special pleasure. For what was a technological vision ten years ago has now become reality. This is the result of the joint efforts of DESY and its international partners – the TESLA Collaboration, which decisively improved the performance of superconducting accelerating cavities.”

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...
