Researchers from Heidelberg University and Sendai University in Japan used new biotechnological methods to study how human cells react to and further process external signals. They focussed on the interaction between so-called G-proteins - the "mediators" of signal transmission - and the receptors known as GPCRs, which trigger signal processes.

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.

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.

Research team discovers previously unknown natural products in soil fungus Mortierella alpina. Life Mortierella alpina lives in the soil and likes to keep cool. This fungus, which belongs to the zygomycetes, grows best at temperatures of 10 to 15°C and occurs mainly in alpine or arctic habitats. In biotechnology, the fungus has been used for the large-scale production of polyunsaturated fatty acids such as arachidonic acids, mainly used as a dietary supplement in baby foods.

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.

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.

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.

Particle accelerator unlocks the secrets of parasite larva Computer-generated image of the larvae of a Strepsiptera (side view) enclosed in a Baltic amber of only about five millimeters. Image: Hans Pohl/FSU When biologist PD Dr Hans Pohl from Friedrich Schiller University Jena discovered an insect fossil encased in amber on eBay, he was thrilled with what he'd found: a 50-million-year-old larva of the order Strepsiptera.

Ecologist Ulrich Brose develops a new method to predict the vulnerability of ecosystems. Predators play a key role. Life Natural ecosystems are as vulnerable as they are diverse. Environmental changes such as climate change, pollution or the spread of alien species can easily throw an ecosystem off balance.

German Research Foundation Extends Funding for Two Collaborative Research Centers at Freie Universität Berlin
Researchers study the dynamics of living together and the scaffolding of membranes No 146/2019 from May 23, 2019 The German Research Foundation (DFG) has extended the funding for two Collaborative Research Centers (CRC) at Freie Universität. One is CRC 958, where scientists study the molecular mechanisms by which dynamically organized protein-protein assemblies scaffold cellular membranes.

Microbial Systems Open a New Chapter in Biosphere Research
A New Study from Freie Universität Berlin in Cooperation with the University of Virginia No 139/2019 from May 21, 2019 In a recent study, biologists from Freie Universität Berlin and the University of Virginia (USA) examine ideas about closed ecological systems and how to further develop them. The goal of the study is to establish concepts that will make it possible to conduct experiments with self-sustaining ecosystems.

Science historians explain Ernst Haeckel's definition of ecology " By ecology, we understand the whole science of the organism's relationship with the surrounding outside world, which includes in a broader sense all 'existential conditions'. These are partly organic and partly inorganic in nature; both the former and the latter are, as we have previously shown, of utmost importance for the form of the organisms, because they force them to adapt to them.

Since the beginning of the year, 40 representatives from renowned research facilities in the Stuttgart region have been working together at the Biointelligence Competence Center to design the paradigm shift of Biological Transformation. The first Biointelligent Products and Production - the Sustainable Industrial Revolution conference took place on the 15 May, where the scientists from the "Biolintelligence Competence Center" submitted their appeal to politicians.

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.

New light-based hardware which can store and process information in a similar way to the human brain / Study published in "Nature" journal A technology that functions like a brain? In these times of artificial intelligence, this no longer seems so far-fetched - for example, when a mobile phone can recognise faces or languages.

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.

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.

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
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.

New research shows: we have to make significant changes to our agricultural practices Life Birds that specialise on insect food have declined across Europe by 13%. This includes the meadow pipit (Anthus pratensis). Image: Mathias Schaef/living-nature.eu The number of birds that primarily feed on insects has decreased significantly during the past 25 years in the European Union.
