The link between obesity, social isolation and mental health
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.

Psychopaths - Cold as Ice?
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.

New drug can extend survival in gastric cancer
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.

Rice with a high protein content developed
Researchers are breeding protein-rich rice varieties that cause minimal increase in blood sugar levels Rice is a staple food for over four billion people. By nature, it contains a lot of carbohydrates but very little protein. A team of researchers from the International Rice Research Institute in the Philippines and the Max Planck Institute of Molecular Plant Physiology in Potsdam, Germany, has now identified the genes that control the carbohydrate composition and protein content of rice.

Researchers from Bonn and Aachen elucidate the role of individual brain neurons in human odor perception We often only realize how important our sense of smell is when it is no longer there: food hardly tastes good, or we no longer react to dangers such as the smell of smoke. Researchers at the University Hospital Bonn (UKB), the University of Bonn and the University of Aachen have investigated the neuronal mechanisms of human odor perception for the first time.

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team at the University of Würzburg has now gained new insights into the DNA damage response. Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic letters before it divides.

Bonn researchers reclassify leading gene variants, a large proportion of them as benign The genetic confirmation of a suspected diagnosis of "hereditary colorectal cancer" is of great importance for the medical care of affected families. However, many of the variants identified in the known genes cannot yet be reliably classified in terms of their causal role in tumor formation.

’Pause Button’ in Human Development
Researchers at the Max Planck Institute for Molecular Genetics in Berlin (MPIMG) and the Institute of Molecular Biotechnology (IMBA) of the Austrian Academy of Sciences in Vienna have discovered a potential "pause button" in the earliest stages of human development. Whether humans can control the timing of their development has long been debated.

Bonn researchers use nanobodies to elucidate pore formation by gasdermin D in cell membranes The formation of pores by a particular protein, gasdermin D, plays a key role in inflammatory reactions. During its activation, an inhibitory part is split off. More than 30 of the remaining protein fragments then combine to form large pores in the cell membrane, which allow the release of inflammatory messengers.

How AI is helping to bridge the research gap between animals and humans
Transferring knowledge from animal experiments to humans remains a key challenge in medical research. This 'translational gap' is often an obstacle to the successful translation of promising preclinical findings into clinical applications. In a joint research project between Leipzig University and Charité - Universitätsmedizin Berlin, scientists have used artificial intelligence to develop an approach that compares the molecular mechanisms of COVID-19 disease in humans and animals.

Researchers from Bonn and Tübingen clarify the neuronal basis of the mathematical concept of "zero" Despite its importance for mathematics, the neuronal basis of the number zero in the human brain was previously unknown. Now researchers from the University Hospital Bonn (UKB), the University of Bonn and the University of Tübingen have discovered that individual nerve cells in the medial temporal lobe recognize zero as a numerical value and not as a separate category "nothing".

How mental states impact gut health
A circuit between the brain and gut influences the gut flora and thus regulates the immune system A study has uncovered a critical brain-gut connection that links psychological states to changes in the gut microbiome, with profound implications for immune function and stress-related health conditions.

A serotonin specific receptor can determine how important visual stimuli are perceived. This explains the effects of certain drugs and could help in understanding psychiatric diseases. Signals in our brain are not always processed in the same way: Certain receptors modulate these mechanisms, influencing our mood, perception, and behavior in various ways.

The birds save more energy prior their migration to the south than they consume during the flight itself Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to research by the Max Planck Institute of Animal Behavior in Konstanz, Germany.
