Autoantibodies (autoAB) against the insulin receptor (IR) are known to cause a rare form of diabetes, i.e. insulin resistance type B. AutoAB against the structurally and functionally related receptor for insulin-like growth factor-1 (IGF1R) have only recently been described and are implicated in autoimmune diseases. However, the prevalence and clinical importance of these autoAB are not yet fully understood as respective sensitive and non-radioactive test systems for routine use were missing. A reliable assay system for the detection and quantification of these autoAB should be met with highest interest by basic researchers and clinicians alike, especially in the fields of diabetes, growth and cancer research, given the central importance of the insulin and IGF1 hormone axes for controlling growth, glucose metabolism and cell proliferation in humans.<br><br> <strong>Technology</strong><br> Two novel non-radioactive and highly sensitive immunoassays for detection and quantification of autoAB against the IR and IGF1R have been developed. For reasons of sensitivity, specificity and automation, the bridge technology has been chosen as most suitable assay format (see scheme). Using these novel in vitro diagnostica, autoAB against the IR and the IGF1R are detected with an astonishing 10% prevalence in the adult population. Notably, a high proportion of cross-reacting autoAB are found, reacting with similar strength to both the IR and IGF1R. The clinical and diagnostic importance of these results remains to be established in ongoing studies.<br><br>

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...
