Coupled Proteins
Coupled Proteins
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.

(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.

Fungus produces highly effective surfactant
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.

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.

Using simulations to understand disruption of space-time
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.

Size is everything
Size is everything
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.

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.
