Circadian clocks control physiological processes and behavior in virtually all living organisms. Now an international research team led by researchers from the University of Würzburg has created a detailed map of the internal clock in the brain of the fruit fly. All animals including humans are subject to daily rhythms in their activity and sleep, hunger, metabolism, and reproduction.

Particulate matter and microplastics are much-discussed risks to the environment and health. A new study by the Center for Earth System Research and Sustainability at the University of Hamburg and the Helmholtz-Zentrum Hereon has now investigated the role of tire and brake wear in the formation of urban particulate matter for the first time.

New therapies could prevent the adjustments in intestinal bacteria that enable them to survive in inflamed regions New studies suggest that evolutionary medicine could shape the future of gastroenterology. They pave the way for new approaches to treating inflammatory diseases, such as chronic inflammatory bowel diseases.

The yeast " Candida parapsilosis" is emerging as a growing threat for hospitalized patients in a new study. A team led by Dr Amelia Barber from the Cluster of Excellence "Balance of the Microverse" at Friedrich Schiller University Jena and Dr Grit Walther from the National Reference Centre for Invasive Fungal Infections (NRZMyk) investigated an outbreak of multi-drug resistant hospital-acquired strain of this fungus.

Study by the University of Bonn shows that deforestation in the Amazon region is also detrimental to human health Rainforest protection is not only good for biodiversity and the climate - it also noticeably improves the health of humans who live in the corresponding regions. This is the conclusion drawn by a current study by the University of Bonn and the Universidade Federal de Minas Gerais in Brazil.

Researchers develop mathematical model to map tumor growth, for example Researchers from the Universities of Bonn and Cologne and the University Hospital of Cologne have developed a three-dimensional mathematical model for prostate cancer. The model depicts various processes, including tumor growth, genetic evolution and competition between tumor cells.

Researchers from the University of Bonn are using an innovative method to watch immune receptors go about their business Immune cells are capable of detecting infections just like a sniffer dog, using special sensors known as Toll-like receptors, or TLRs for short. But what signals activate TLRs, and what is the relationship between the scale and nature of this activation and the substance being detected? In a recent study, researchers from the University of Bonn and the University Hospital Bonn (UKB) used an innovative method to answer these questions.

A team of biologists from the University of Münster has investigated whether and how the immune system can influence the behaviour of sticklebacks It's a well-known fact that if you don't get enough sleep, you're more likely to get sick. And it has also been observed that people sleep differently when they're infected.

Researchers from Bonn uncover how tiny eye movements and the density of our photoreceptors aid in sharp vision Our ability to see starts with the light-sensitive photoreceptor cells in our eyes. A specific region of the retina, termed fovea, is responsible for sharp vision. Here, the color-sensitive cone photoreceptors allow us to detect even the smallest details.

Head and neck cancers are among the ten most common cancers worldwide. Head and neck tumors account for about three to five percent of all cancers, with squamous cell carcinomas being the predominant form. They occur in areas such as the oral cavity, pharynx and larynx. An international team of researchers led by Sara Wickström has now developed a new technique that allows the properties of cancer cells and their surrounding tissue to be analyzed in detail at the single-cell level.

Mushrooms come in a breathtaking variety of shapes, colors and sizes. Especially in autumn, mushroom hunters swarm into the forests to find the tastiest of them, prepare them in a variety of ways and eat them with relish. However, it is well known that there are also poisonous mushrooms among them, and it is vital to distinguish between them.

News from Researchers at Leipzig University have examined the complex relationships between obesity, social isolation and mental health in the German adult population. Their findings show that socially isolated obese people are at increased risk of mental illness. Particularly at risk are the elderly, the widowed and men of lower socio-economic status.

New imaging data reveal that the follicle expands, contracts, and finally releases the egg Approximately 400 times in a woman's life, a mature egg makes the -leap. It is released into the fallopian tube, ready for fertilization by the sperm. Researchers led by Melina Schuh, Christopher Thomas, and Tabea Lilian Marx from the Max Planck Institute for Multidisciplinary Sciences have now succeeded in visualizing the entire process of ovulation in mouse follicles in real-time.

Psychopathic people have great difficulty or are even unable to show empathy and regulate their emotions. According to a new study by Matthias Burghart, a Max Planck researcher in Freiburg, this could be because these people suffer from alexithymia, also known as emotional blindness. The term alexithymia is an amalgam of the Greek prefix a- (without) and the words lexis (reading) and thymos (emotion).

Chemicals are omnipresent today: they enter our bodies through food, air or the skin. But how do these complex mixtures of chemicals affect our health? In a study published in the journal Science, a research team from the Helmholtz Centre for Environmental Research (UFZ) and the University of Tübingen has shown that chemicals that occur in complex mixtures and in concentration ratios as found in humans act together.

First mRNA stabilizing substance could open new ways in the development of innovative mRNA therapeutics   mRNA-based therapeutics and vaccines are the new hope in the fight against incurable diseases. A commonly used strategy in the development of messenger RNA ( mRNA) medicine is based on the destruction of disease-causing mRNA.

Just a matter of the head? Not at all: Psychologist Dr. Barbara Schmidt from Jena University Hospital investigated the influence of hypnosis on our physical performance in a study now published in the journal "Scientific Reports". The results showed that hypnosis can not only increase the subjective feeling of strength, but also objective strength - with long-lasting effects.

In Germany, around 17,000 people are diagnosed with gastric cancer every year. The disease is one of the leading causes of tumour-related deaths. This is due to late diagnosis and the rapid spread of tumour cells throughout the body. In two international clinical trials, a team of scientists involving the University of Leipzig Medical Center have investigated a drug that can prolong patients' survival.

Current findings from a Jena-Zurich research project form an important basis for the creation of artificial symbioses with specific properties that could be used for biotechnological applications in the future. For example, they could be used in Medicine, agriculture or environmental technology to protect plants against illnesses or to modify fungi so that they produce certain enzymes or active pharmaceutical ingredients.

Researchers at the University of Leipzig Medical Center have deciphered a new mechanism that plays a central role in the development of diabetic kidney disease. Their study focuses on a coagulation protein. It can be detected in urine samples from patients in the early stages of the disease and can be used as a diagnostic marker.
