Orangutans show pre-requisites for stone tool technologies
Orangutans show pre-requisites for stone tool technologies
Basic skills for using stone tools may be more widespread among primates than we previously thought: A study led by researchers from the University of Tübingen in collaboration with the Max Planck Institute of Evolutionary Anthropology in Leipzig and the University of Barcelona shows that orangutans spontaneously recognize and use human-made sharp stones as cutting tools.

How Embryo Cells Gain Independence
How Embryo Cells Gain Independence
Freiburg researchers elucidate how signaling molecules from the mother give the starting signal for gene expression in their offspring It happens in the first hours after fertilization: The cells of the early embryo begin to independently produce proteins, the building blocks for cells and organs. Their own, uniquely composed genetic material serves as the blueprint.

Recently identified protein group plays major role in nature
Recently identified protein group plays major role in nature
Göttingen researchers find protein switch they discovered regulates enzymes in pathogens Proteins are the -workhorses- in every living cell and constitute the chemical basis of life. These little machines are required to turn food into energy, to manage motion and brain activities and to fight off bacteria and viruses.

Mitochondria efficiently adapt to changing metabolic conditions
Mitochondria efficiently adapt to changing metabolic conditions
Freiburg researchers show that two protein complexes can communicate with each other A recent study explains an essential component for proper mitochondrial function: The protein complexes MICOS and ATP synthase can communicate with each other. Dr. Heike Rampelt and Prof. Dr. Nikolaus Pfanner at the Institute of Biochemistry and Molecular Biology of the University of Freiburg have uncovered an important mechanism that ensures efficient metabolic adaptation of mitochondria.

Protection from the Molecular Shredder
Heidelberg plant researchers discover cellular mechanism that extends the life of proteins Plants are tied to one location and need to adjust to their environment, including adverse conditions. Adaptive responses include synthesising new proteins and breaking down those that are no longer needed. For this task, plants use a considerable amount of energy.

Intelligence - It’s all about connectivity
Human intelligence is closely associated with functional brain networks: The better these networks are developed, the easier it is for the brain to adapt to different tasks, this is shown by a new study of the University of Würzburg. You are just enjoying a nap on the sofa when your son suddenly turns up and asks you to help him with his math homework.

Rare rockcress species in the Rhine meadows seem able to prevent their own extinction
In the floodplains of the Rhine River near the city of Mainz, two different rockcress species are intercrossing. This results in a mixed population with higher genetic diversity, where a kind of 'super genotype' consisting of a patchwork of the two populations could emerge, ensuring the survival of the two species.

How a fungus hijacks our immune system
How a fungus hijacks our immune system
During infection, the yeast Candida albicans stimulates the release of tiny RNA fragments, which then stimulate its own growth. An international research team led by the Leibniz Institute for Natural Product Research and Infection Biology - Hans Knöll Institute (Leibniz-HKI) in Jena has discovered this unusual exploitation of the human immune system.

Genome of Steller’s Sea Cow Decoded
During the Ice Age, giant mammals such as mammoths, sabre-toothed cats and woolly rhinoceroses once roamed Northern Europe and America. The cold oceans of the northern hemisphere were also home to giants like Steller's sea cow, which grew up to eight metres long and weighed up to ten tonnes, and has been extinct for around 250 years.

How our body controls inflammation during clean-up mechanisms of damaged cells
A research team from Cologne and Osnabrück has investigated in detail how messenger substances signal inflammation during the removal of damaged cells in the body. Using high-resolution microscopy methods, the researchers were able to show that two proteins interact dynamically with each other and thus determine whether a dying cell triggers an inflammatory reaction in the body.

A sponge playing in defence
A sponge playing in defence
Bacteria are extremely resourceful when it comes to adapting to a given environment. A team of researchers from Würzburg has now discovered a new trick bacteria use: a kind of sponge that absorbs certain messengers. Each year, at least 1.27 million people die from an infection with bacteria that are resistant to standard antibiotics, a study recently published in the journal The Lancet reveals.

First 3D structure of regulator protein revealed
First 3D structure of regulator protein revealed
Proteins are indispensable components in living organisms. They are not only "building material" for the body - they also make molecular communication between cells possible, they are needed for nerve impulses to occur, and they control chemical reactions. What is decisive for proteins to function is their three-dimensional structure.

Cause of inflammatory bowel disease discovered
Cause of inflammatory bowel disease discovered
Chronic inflammatory bowel disease (IBD) is becoming increasingly widespread. Until now, however, the underlying causes of the inflammation responses were unclear. Scientists at the Technical University of Munich (TUM) have now identified a mechanism that triggers a problematic interaction between intestinal bacteria and cells in the intestinal mucus layer in XLP2, a condition associated with IBD.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases - test subjects wanted! [Picture: NASA] Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

Protein machinery of respiration becomes visible
Protein machinery of respiration becomes visible
Researchers provide high-resolution electron microscopy analysis of the molecular machinery within the respiratory chain Oxygen and sugar are the basis of life for animals, plants, fungi and many bacteria. The metabolic process called respiration makes it possible to convert food into energy for the cells.

Immune cells as squatters
Immune cells as squatters
Human immune cells not only circulate in the blood, but can also occupy certain tissues and sometimes remain there for years. A research team led by immunologist Christina Zielinski discovered this phenomenon by examining patient samples after stem cell transplantation. In addition, the researchers were able to characterize the special properties of tissue-resident immune cells in more detail.

Human disturbance is the most crucial factor for lynx in habitat selection
A new data analysis provides important information on the habitat selection of these predators Habitat selection in wildlife is a process that occurs at different scales: Balancing advantages, such as high abundance of food, with disadvantages, such as human disturbance. Large predators, with their large spatial requirements, are particularly sensitive to these disturbances.

Help for stressed-out cells in a crisis
Help for stressed-out cells in a crisis
According to a team of researchers at the University of Münster, mitochondria provide unexpected help for cells in a crisis by respiring away harmful substances. A current study produced by the Institute of Biology and Biotechnology of Plants (IBBP) shows three things: that this mechanism can be triggered by reductive stress, that it protects the folding of certain proteins destined for export, and that the cell's "powerhouse" consequently acts even more flexibly than was previously known.
