Bouncers in the Bone Marrow
Bouncers in the Bone Marrow
07/19/2019 Würzburg Scientists found that megakaryocytes act as "bouncers" and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in the Journal "Haematologica". Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow.

The physiology of survival
The physiology of survival
The survival and growth of cells are central factors in biological systems. Scientists such as Ulrich Gerland, Professor for Physics of Complex Biosystems at the TUM, are therefore trying to understand how the molecular components interact to maintain the viability of a group of cells in stress situations.

The battle between virus and host cell
The battle between virus and host cell
Würzburg Scientists have precisely followed the activity of thousands of genes in individual cells for hours. For the first time, they were able to show why some cells are successfully infected by viruses, whereas others are not. When viruses enter our bodies - such as during an influenza or a gastrointestinal infection - the processes within the infected cells change: In the worst case, the virus takes the helm and reprograms the cell to its advantage.

Neuroplasticity: Why is the visual cortex involved in language processing in blind individuals?
A study by neuroscientists of the Brain Language Laboratory at Freie Universität Berlin No 204/2019 from Jul 05, 2019 People who are blind use part of their visual cortex for language and semantic processing. The visual cortex is the paradigm case of a "modality-specific" brain region, being devoted exclusively to visual perceptual processes in healthy and undeprived sighted individuals.

Scientists alarmed by bark beetle boom
Scientists alarmed by bark beetle boom
Bark beetles are currently responsible for killing an unprecedented number of trees in forests across Europe and North America. Researchers are therefore urging to step up research into bark beetles - also in view of climate change. "Bark beetles lay waste to forests" - "Climate change sends beetles into overdrive" - "Bark beetles: can the spruce be saved?": These newspaper headlines of the past weeks covered the explosive growth of bark beetle populations and its devastating impact on timberlands.

One at a time
One at a time
It is becoming much more common for patients to be treated with several different medications. It is often necessary for the patient to take them at fixed intervals - a limitation that makes everyday life difficult and increases the risk of doses being skipped or forgotten.

(Not only) the wind shows the way
(Not only) the wind shows the way
06/24/2019 When the South African dung beetle rolls its dung ball through the savannah, it must know the way as precisely as possible. Scientists have now discovered that it does not orient itself solely on the position of the sun. The South African dung beetle Scarabaeus lamarcki has - to put it mildly - an interesting technique to ensure its offspring a good start in life.

Cell Division at High Speed
Cell Division at High Speed
06/19/2019 When two proteins work together, this worsens the prognosis for lung cancer patients: their chances of survival are particularly poor in this case. In malignant tumours, the cells usually proliferate quickly and uncontrollably. A research team from the Biocenter of Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, has discovered that two important regulators of cell division can interact in this process.

Tox
Tox "exhausts" immune cells
Normally, the immune system goes into a state of maximum alert following a viral infection. It triggers the activation of a variety of immune cells such as T and B cells. These procreate in large numbers, and aggressively combat the infected cells. However, if the immune system does not manage to defeat the virus, then immune cells appear with highly inhibited functions.

Why does dandelion never fall ill?
Why does dandelion never fall ill?
Researchers at Münster University find out that dandelion possesses enzymes that have untypical abilities for plants / Study in "Angewandte Chemie' Plants possess enzymes called polyphenoloxidases, which can oxidize certain chemical compounds and thus produce the typical brown colour that we know, for example, from freshly cut apples.

Second grant to bring research to market
05/14/2019 Getting an accurate picture of the real-time transcriptional activity of a cell: This is the goal of a new research project at the University of Würzburg which is funded by the European Research Council. If you paid attention during biology lessons, you may remember that genetic information in human cells is contained in the cell nucleus as a DNA double helix.

Trigger for directed cell motion
When an individual cell is placed on a level surface, it does not keep still, but starts moving. This phenomenon was observed by the British cell biologist Michael Abercrombie as long ago as 1967. Since then, researchers have been thriving to understand how cells accomplish this feat. This much is known: cells form so-called lamellipodia - cellular protrusions that continuously grow and contract - to propel themselves towards signalling cues such as chemical attractants produced and secreted by other cells.

How plants defend themselves
How plants defend themselves
Like humans and animals, plants defend themselves against pathogens with the help of their immune system. But how do they activate their cellular defenses' Researchers at the Technical University of Munich (TUM) have now discovered that receptors in plant cells identify bacteria through simple molecular building blocks.

Reproduction: How male flies enforce their interests
Reproduction: How male flies enforce their interests
The fundamental biological process of reproduction can differ greatly from animal species to species. Both males and females sometimes evolve creative strategies in pursuing their interests in these mating interactions. This has been studied for quite some time in small species such as the fruit fly Drosophila melanogaster, where the female receives proteins through the male's seminal fluid - which, after the actual mating, leads to radical changes in her behaviour and in the processes occurring inside her body.

New Pathways for Sustainable Agriculture
New Pathways for Sustainable Agriculture
Diversity beats monotony: a colourful patchwork of small, differently used plots can bring advantages to agriculture and nature. This is the result of a new study by the University of Würzburg. Hedges, flowering strips and other seminatural habitats provide food and nesting places for insects and birds in agricultural landscapes.

How do muscle and tendon connections last a lifetime?
How do muscle and tendon connections last a lifetime?
Muscles are connected to tendons to power animal movements such as running, swimming or flying. Forces are produced by contractile chains of the proteins actin and myosin, which are pulling on muscle-tendon connections called attachments. During animal development, these muscle-tendon attachments must be established such that they resist high mechanical forces for the entire life of the animal.
