Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilised gamete s'and thrive without males. They used -Amazonalgae to shed light on the phenotypic and genetic consequences of shift from sexual to asexual reproduction.

It's not just us humans who suffer from heatwaves. Researchers at the University of Würzburg discovered that hot temperatures rob bumblebees of their sense of smell - and makes them struggle when searching for food. Climate change is affecting ecosystems in many different ways. One of its consequences are increasingly longer and more intense periods of heat, which affect essential natural processes - such as pollination.

The chemical composition triggers upwelling of mantle currents from Earth's interior / Findings published in "Nature Geoscience" journal Researchers around the world investigate the dynamic processes in Earth's deep interior, hundreds to thousands of kilometers below the surface. These processes drive plate movements and volcanism but still keep many secrets.

Researchers from Würzburg and Berlin present a new molecule for visualising the sphingomyelin metabolism. This offers prospects for innovative therapeutic approaches in infection research. At the end of the 19th century, the German pathologist Ludwig Thudichum isolated previously unknown fatty substances (lipids) from the brain.

Using newly generated "optogenetic" tobacco plants, research teams from the University of Würzburg's Departments of Plant Physiology and Neurophysiology have investigated how plants process external signals. When it comes to survival, plants have a huge disadvantage compared to many other living organisms: they cannot simply change their location if predators or pathogens attack them or the environmental conditions change to their disadvantage.

Study by University of Bonn: Where measures against illegal deforestation are in force, the number of homicides falls In December 2007, the then Brazilian government passed a law to curb the illegal destruction of the rainforest. A study by researchers from the Insper Research Institute in São Paulo and the University of Bonn now shows an interesting side effect: where the measures were implemented, not only did deforestation decrease, but so did the number of homicides.

Letting go of learned fears is difficult. New research findings reveal that the environment in which we learn the fear could also play a crucial role in unlearning it. When we learn something, we can usually recall it in any new context: If someone passes their driving test in France, they can also drive a car in Germany.

All higher organisms such as fungi, plants, animals and humans consist of eukaryotic cells. These are cells that have a nucleus and organelles such as mitochondria. Mitochondria supply eukaryotic cells with energy. In contrast to eukaryotes, prokaryotes are unicellular organisms. They have a simpler structure and are mostly significantly smaller than eukaryotes.

Study on fruit flies' ability to reliably perceive threats during courtship carried out by researchers from Birmingham and Berlin published in "Nature" The results of an international study carried out by researchers from the University of Birmingham and Freie Universität Berlin show that male fruit flies are more likely to ignore dangers such as predators during courtship.

News from Terrestrial ecosystems become increasingly vulnerable to global change as the number of environmental stressors rises, according to a new study published in Nature Geoscience.

A team of scientists from the Cluster of Excellence "Balance of the Microverse" has discovered a previously unknown rejuvenation mechanism in unicellular organisms. They studied unicellular microalgae, which serve as the basis of food chains in the oceans. Unicellular organisms, such as microalgae, also age when they can no longer divide due to a lack of nutrients.

When combined with antifungal drugs, synthetic polymers are particularly effective against the yeast Candida albicans . This is what a German-Australian research team found out and also clarified the mechanism of action behind it. The researchers presented their findings in the journal "Nature Communications".

Superconductivity theory proposed by Würzburg physics team validated in international experiment: Cooper pairs display wave-like distribution in Kagome metals, enabling new technological applications like superconducting diodes. For about fifteen years, Kagome materials with their star-shaped structure reminiscent of a Japanese basketry pattern have captivated global research.

Chlamydiae are sexually transmitted pathogens that can apparently survive in the human gut for a long time. Researchers from Würzburg and Berlin report this in the journal PLOS Pathogens. People who are infected with chlamydia can transmit these bacteria to other people during unprotected sex. The pathogens usually cause no or only mild symptoms at first, such as itching in the vagina, penis or anus.

University of Bonn study: regulated degradation of damaged cell components prevents heart failure and nerve diseases The elimination of damaged cell components is essential for the maintenance of the body's tissues and organs. An international research team led by the University of Bonn has made significant findings on mechanisms for the clearing of cellular wastes, showing that strength training activates such mechanisms.

Bonn researchers clarify self-regulation of the immune response in the CRISPR bacterial defense system CRISPR gene scissors, as new tools of molecular biology, have their origin in an ancient bacterial immune system. But once a virus attack has been successfully overcome, the cell has to recover. Researchers from the University Hospital Bonn (UKB) and the University of Bonn, in cooperation with researchers from the Institut Pasteur in France, have discovered a timer integrated into the gene scissors that enables the gene scissors to switch themselves off.

Researchers confirm positive effects of organic farming and flower strips for bee colonies   Honey bees are valued both for their honey and their ability to pollinate crops. However, populations are suffering from the loss of areas of wild flowers in intensive farming, pesticide applications and from the influence of pathogens, so it is all the more important to understand what keeps them healthy.

Together with an international team of researchers, Freie Universität Berlin bioarchaeologist Sarah Defant is shedding light on how rural communities in northern Italy developed following the fall of the Roman Empire How did political shifts in power and migration influence how rural communities developed after the fall of the Roman Empire?

Rohingya children, whose lives have been marked by flight and displacement, have retained their prosociality as a fundamental human trait in the face of adversity.

Baby sea turtles respond even more to fluctuating precipitation than to changes in air temperature during their development in the egg. The effects of precipitation differ depending on the species - or even the population.
