A Peek into the Birthing Room? of Ribosomes
A Peek into the Birthing Room? of Ribosomes
A type of scaffolding on which specialised workers ply their trade helps in the manufacturing process of the two subunits from which the ribosome - the protein factory of the cell - originates. Biochemists at Heidelberg University discovered it after succeeding in getting a peek into the ribosomal 'birthing room'.

The key to self-destruction
The key to self-destruction
Research news When adults develop blood cancer, they are frequently diagnosed with what is referred to as acute myeloid leukemia. The disease is triggered by pathological alterations of bone marrow cells, in which, in addition, an important mechanism is out of action: these cells do not die when they are damaged.

Two Kinds of Beta Cells
Two Kinds of Beta Cells
Research news The marker Flattop subdivides the insulin-producing beta cells of the pancreas into those that maintain glucose metabolism and into immature cells that divide more frequently and adapt to metabolic changes. This could provide a starting point for regenerative diabetes therapies, as scientists of the Technical University of Munich (TUM), in collaboration with colleagues of Helmholtz Zentrum München and the German Center for Diabetes Research (DZD), report in the journal 'Nature'.

Thousands on one chip: New Method to Study Proteins
Thousands on one chip: New Method to Study Proteins
Research news Since the completion of the human genome an important goal has been to elucidate the function of the now known proteins: a new molecular method enables the investigation of the function for thousands of proteins in parallel. Applying this new method, an international team of researchers with leading participation of the Technical University of Munich (TUM) was able to identify hundreds of previously unknown interactions among proteins.

No 233 from Jun 29, 2016 Deformed Wing Virus: Honeybees Threatened by a More Virulent Virus Researchers reveal geographic distribution of emerging viral variants
Researchers reveal geographic distribution of emerging viral variants No 233/2016 from Jun 29, 2016 According to an international research group, a genetic variant of the deformed wing virus (DWV) is more dangerous to honeybees than the original virus strain. The consortium of researchers is based at Freie Universität Berlin and Martin Luther University Halle-Wittenberg.

Gene mutation causes juvenile mortality in calves
Gene mutation causes juvenile mortality in calves
Research news Based on genome data, breeders and scientists are able to determine which hereditary factors and which genetic diseases cattle pass on to their offspring. A mutation located on chromosome 19, for example, is responsible for recurring respiratory diseases and juvenile mortality in calves.

Four new risk genes associated with multiple sclerosis discovered
Four new risk genes associated with multiple sclerosis discovered
Research news Scientists of the Technical University of Munich (TUM) and the Max Planck Institute of Psychiatry have identified four new risk genes that are altered in German patients with multiple sclerosis (MS). The results point to a possible involvement of cellular mechanisms in the development of the disease, through which environmental influences affect gene regulation.

Mechanism of thalidomide
Mechanism of thalidomide
Research news In the 1950s, thalidomide (Contergan) was prescribed as a sedative drug to pregnant women, resulting in a great number of infants with serious malformations. Up to now, the reasons for these disastrous birth defects have remained unclear. Researchers at the Technical University of Munich (TUM) have at last identified the molecular mechanism of thalidomide.

A diet lacking in zinc is detrimental to human and animal health
Research news The trace element zinc has an impact on the essential metabolic functions of most living organisms. New research carried out by the Chair of Animal Nutrition at the Technical University of Munich (TUM) has found that even minimal zinc deficiency impairs digestion, albeit without any typical symptoms such as skin problems or fatigue.

Reading between the genes
Research news For a long time dismissed as "junk DNA", we now know that also the regions between the genes fulfil vital functions. Mutations in those DNA regions can severely impair development in humans and may lead to serious diseases later in life. Until now, however, regulatory DNA regions have been hard to find.

Universität Heidelberg Garners Four Approvals for Collaborative Research Centres
Heidelberg University succeeded in gaining support from the German Research Foundation (DFG) in the latest approval round, recieving funding for four research networks. The DFG granted funds to the new Transregional Collaborative Research Centre (CRC/TRR) of the Heidelberg Medical Faculty, where researchers from Heidelberg, Freiburg and Munich will investigate viral hepatitis infections.

No 182 from May 27, 2016 German Research Foundation Awards Freie Universität Berlin Two New Collaborative Research Centers Approval for Two New Ones and Extension for Two Others
The German Research Foundation (DFG) has approved funding for two new Collaborative Research Centers (CRC) at Freie Universität Berlin, as well as funding extensions for two others already established at Freie Universität. The new CRCs, to be funded for four years, are "Entangled States of Matter," Transregio (TRR) 183, in cooperation with the University of Cologne, and CRC/TRR 186, "Molecular Switches: Spatio-Temporal Control of Cellular Signal Transmission," in cooperation with the University of Heidelberg.

Building-blocks of life
Biological evolution was preceded by a long phase of chemical evolution during which precursors of biopolymers accumulated. LMU chemists have discovered an efficient mechanism for the prebiotic synthesis of a vital class of such compounds. How did life originate on Earth and what were its chemical building-blocks? One possible source of answers to these questions can be found in outer space.

Lethal reawakening
Retroviral DNAs integrate into host genomes, but their expression is normally repressed by cellular defense mechanisms. As an LMU team now shows, when these measures fail, accumulation of viral proteins may trigger programmed cell death. Mammalian DNAs contain large numbers of sequences that are derived from retroviral genomes, which integrated into the germline of the host and were passed on to its descendants during the course of evolution.

How Fish Can Regenerate Eye Injuries at the Cellular Level
How Fish Can Regenerate Eye Injuries at the Cellular Level
Confocal microscopy image of a section through the medaka fish retina. Single Müller glia and photoreceptor cells are labelled in different colours by a genetic system (red, green, yellow). Atoh7 expression in Müller glia cells leads a regeneration response in the absence of injury, including expansion of the cell soma and neurogenic cluster formation.

Werner Siemens Foundation fosters synthetic biotechnology
Campus news With its donation of 11.5 million euro, the Werner Siemens Foundation has facilitated the launch of the teaching and research domain Synthetic Biotechnology at the Technical University of Munich (TUM). This gives the new TUM School of Bioengineering (MSB) a strong accent as an Integrative Research Center.

Live is motion
LMU physicists have developed a way to distinguish the random motions of particles in non-living molecular systems from the motility of active living matter. The method affords new insights into fundamental biological processes. Any system in thermodynamic equilibrium is known to satisfy perfectly balanced forward and backward transitions between any two states.

Closing the ring
How bacterial cells divide in two is not fully understood. LMU physicists now show that, at high concentrations, a crucial protein can assemble into ring-shaped filaments that constrict the cell, giving rise to two daughter cells. Above a certain threshold particle density (subunit concentration), the rotational movement of, and collisions between, the curved polymers lead to the formation of clustered ring-like structures.

Predicting Cell Behaviour with a Mathematical Model
Predicting Cell Behaviour with a Mathematical Model
Scientists from Heidelberg University have developed a novel mathematical model to explore cellular processes: with the corresponding software, they now are able to simulate how large collections of cells behave on given geometrical structures. The software supports the evaluation of microscope-based observations of cell behaviour on micropatterned substrates.
