Resurrecting billon-year-old enzymes reveals how photosynthesis adapted to the rise of oxygen The central biocatalyst in Photosynthesis, Rubisco, is the most abundant enzyme on earth. By reconstructing billion-year-old enzymes, a team of Max Planck Researchers has deciphered one of the key adaptations of early photosynthesis.

In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team led by Dr Francesca Ciccolini at the Interdisciplinary Center for Neurosciences (IZN) of Heidelberg University recently discovered a second stem cell population in the mouse brain.

First-of-its-kind study identifies physiological changes in the transition to siblinghood In any family, the birth of a child is a transformative event, often greeted with positive feelings from parents-and mixed feelings from siblings. The arrival of a new brother or sister, and the loss of parental attention that comes with it, is stressful for any first-born child.

Bacteria produce antifungal compound protecting the eggs, larvae, and pupae from infections / Bacterial community is retained even during molting stages Lagria beetles have developed unusual physical traits to protect their progeny: Small invaginations on the backs of the larvae are inhabited by defensive bacteria.

Electronic comparison of MRI images opens up new possibilities for early detection of diseases The biological age of a person can be accurately determined from brain images using the latest AI technology, so-called artificial neural networks. Until now, however, it was unclear which features these networks used to infer age.

Research team led by Göttingen University identify DNA -hotspots- that tell zebrafish to change sex in warmer waters. Environment leaves its mark on genome through DNA methylation. In many species, such as zebrafish, sex is partly or completely determined by the environment. Genes can predispose to a particular sex but may be -overruled- by the influence of the environment, for example temperature or population density.

Study shows effect on amygdala in temporal lobe The bacterial toxin botulinum toxin (BTX) - colloquially known as Botox - is probably known to most people as a remedy for wrinkles. But botulinum toxin can do even more: if it is injected into the forehead, for example, it can alleviate depression.

Together with researchers from University Hospital Mainz, the University of Regensburg and the IRCM in Montreal (Canada), a research team from Friedrich Schiller University Jena has discovered a novel therapeutic approach for treating malignant tumours of the lymphatic system. The team led by Dr Christian Kosan from Jena University's Institute of Biochemistry and Biophysics shows that treating certain B-cell lymphomas with the enzyme inhibitor "Marbostat 100" leads to significantly slowed growth of the tumour cells.

Archaeogenetic study reveals large-scale continental migration into the East of England during the early Medieval Period In the largest early-medieval population study to date, an interdisciplinary team consisting of geneticists and archaeologists - led by the Max Planck Institute for Evolutionary Anthropology and the University of Central Lancashire - analysed over 400 individuals from ancient Britain, Ireland, Germany, Denmark and the Netherlands.

Study by the University of Bonn follows an innovative path in the search for new active substances The zebrafish serves as a model organism for researchers around the world: it can be used to study important physiological processes that also take place in a similar form in the human body. It is therefore routinely used in the search for possible active substances against diseases.

Have you ever asked yourself this question? A team led by Würzburg biologists Dr. Patrick Schultheiss and Dr. Sabine Nooten now has the answer. In addition to the number, the distribution was also determined. How many stars are there in our galaxy? How many grains of sand in the Sahara? How many ants live on Earth? These are all questions that seem impossible to answer.

Researchers at the University of Bonn transplant RNA editing machine of a moss into human cells If everything is to run smoothly in living cells, the genetic information must be correct. But unfortunately, errors in the DNA accumulate over time due to mutations. Land plants have developed a peculiar correction mode: they do not directly improve the errors in the genome, but rather elaborately in each individual transcript.

A study of moles reveals that cold weather - not lack of food - drives the rare phenomenon of reversible brain shrinkage in mammals In the depths of winter, European moles face an existential problem. Their metabolisms - close to the upper limit of any mammal - require more food than is available during the coldest months.

Researchers at Johannes Gutenberg University Mainz examine ways of alleviating depressive states using the Drosophila fruit fly as a model Human beings and fruit flies have very little in common - at first sight. However, studying these flies it is in fact possible to find out more about human nature, particularly when it comes to depressive disorders.

Biosynthetic pathway of the light-harvesting carotenoid fucoxanthin is surprisingly complex / Photoprotective pigments serve as precursors Diatoms are microscopic unicellular algae occurring in natural waters worldwide. During photosynthesis, they take up large quantities of carbon dioxide, the primary greenhouse gas emitted through human activities, and convert it into biomass.

Researchers discover simultaneous evolutionary history of gut microbes with their human hosts over hundreds of thousands of years The human gut microbiome is composed of thousands of different bacteria and archaea that vary widely between populations and individuals. Scientists from the Max Planck Institute for Biology in Tübingen have now discovered gut microbes that share a parallel evolutionary history with their human hosts: the microorganisms co-evolved in the human gut environment over hundreds of thousands of years.

The hemispheres are not equal
A study analyzes differences in brain asymmetry among different individuals Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right - and each person's processing is a little different. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences and Forschungszentrum Juelich, together with an international team of neuroscientists, have now discovered heritable underpinnings of brain asymmetry - and - how much we share with monkeys.

In the cultivation of organic cacao, many factors determine the yield. An international research team has now identified important players and their combined effects. It's not possible to grow cacao without insects - that's logical. After all, they ensure that the flowers are pollinated and that the valuable cacao fruits, a sought-after material for the food industry, develop.

Research team led by the Universities of Göttingen and Würzburg highlights importance of critical animal species Without insects, there would be no cacao - a much-desired raw material for the food industry. Insects ensure that the flowers are pollinated and that the cacao fruits develop. In addition, birds and bats contribute significantly to increasing the crop yield.
