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.

Love is Blind?
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.

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.

Gene scissors switch off with built-in timer
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.

The Role of Emerging Elites in the Formation of Post-Roman Italian Society
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?

Until recently, little was known about Bishop Teodomiro, after St James the Apostle one of the most important figure associated with the pilgrimage to Santiago de Compostela. Now, a interdisciplinary investigation has conducted a comprehensive analysis of the potential remains of the bishop using advanced techniques.

Using the largest dataset of human fossils from Ice Age Europe to date, an international research team shows how prehistoric hunter-gatherers coped with climate change in the period between 47,000 and 7,000 years ago.

An international research team has sequenced the largest genomes of all'animals - those of lungfish. The data will help to find out how the ancestors of land vertebrates managed to conquer the mainland. Let's travel back through time to the late Devonian period, around 380 to 360 million years in the past.

Aerobic methane-oxidizing bacteria are also permanently active in oxygen-free water Methane-oxidizing bacteria could play a greater role than previously thought in preventing the release of climate-damaging methane from lakes, researchers from Bremen report. They also show who is behind the process and how it works.

Memory loss, confusion, speech problems - Alzheimer's disease is the most common cause of dementia, affecting about 35 million people worldwide, and the number is growing. The protein amyloid beta, which occurs naturally in the brain, plays a central role in the disease: It accumulates in patients in insoluble clumps that form plaques between neurons in the brain, damaging them.

Mast cells trap and use living neutrophils during allergic reactions Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation.

The brain is constantly storing new experiences that it has to integrate into the jumble of existing memories. Surprisingly, it does not overwrite previous memory traces in the process. The first day of school: entering the classroom for the first time, the excited feeling in your stomach and the joy of having a school bag - these are all typical examples of memories from our episodic memory.

Known for their role in allergic reactions, mast cells have long been recognised as key players in our immune system. When they encounter allergens, they release chemicals that trigger typical allergy symptoms such as tissue swelling and inflammation. Now, researchers at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and the University of Münster have discovered a hidden talent of mast cells: they can capture and use another type of immune cell called neutrophils.

Immune cells in the brain form bridges to nerve cells and protect against neurodegenerative diseases When nerve cells in the brain die, diseases such as Alzheimer's and Parkinson's develop. To protect these cells, there are immune cells in the brain known as microglia. A study has now shown that microglia form tiny tubes, so-called -tunnelling nanotubes-, and thus connect directly to the nerve cells.

In a collaborative project between the Faculty of Veterinary Medicine and the Interdisciplinary Centre for Bioinformatics (IZBI) at Leipzig University, changes in gene expression in sebaceous glands have been spatially mapped for the first time. The study documents at high resolution changes in gene expression in the course of sebum synthesis and identifies new candidates for the modulation of sebum production.

We all know what it's like when the penny suddenly drops. Animals too experience such moments of insight. They could prove useful for research, according to Ekrem Dere. For generations, researchers have been pondering the question of how and where consciousness is formed in the brain. Professor Ekrem Dere from Ruhr University Bochum, Germany, proposes a new approach to researching conscious cognitive information processing.
