The German Research Foundation (DFG) has established a new Collaborative Research Center on "Nanodimensional polymer therapeutics for tumor therapy" (CRC 1066) at Johannes Gutenberg University Mainz (JGU) and the Max Planck Institute for Polymer Research (MPI-P). Starting in October 2013, the Collaborative Research Center will receive grants totaling approximately EUR 11 million over four years to develop a nanoparticle-based cancer therapy to combat melanoma as an immunogenic tumor model.
The Mainz scientists will focus on a form of cancer immunotherapy that is specifically suitable for permanently eliminating minimal residual disease, such as hidden metastases. The new CRC is notable for its interdisciplinary approach: chemists will study the synthetic feasibility and the structure-property relationships of carrier materials, while immunologists and biomedical specialists develop models for the optimal use of such carriers – in the form of a new combination therapy for activating the body’s immune response against the cancer.The coordinator of the new DFG-funded Collaborative Research Center is Professor Rudolf Zentel from the Institute of Organic Chemistry at Johannes Gutenberg University Mainz. Assistant coordinators are Professor Stephan Grabbe from the Department of Dermatology at the Mainz University Medical Center and Professor Katharina Landfester from the Max Planck Institute for Polymer Research in Mainz. In addition, the Board of Directors will include Professor Detlef Schuppan from the Department of Internal Medicine I at the Mainz University Medical Center and Dr. Mathias Barz from the JGU Institute of Organic Chemistry as a representative of young researchers.

The pyrenoid is a carbon-fixing liquid droplet

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...
