Dieting: brain amplifies signal of hunger synapses
Many people who have dieted are familiar with the yo-yo effect: after the diet, the kilos are quickly put back on. Researchers from the Max Planck Institute for Metabolism Research and Harvard Medical School have now shown in mice that communication in the brain changes during a diet: The nerve cells that mediate the feeling of hunger receive stronger signals, so that the mice eat significantly more after the diet and gain weight more quickly.

The glycoprotein V of the blood platelets is an important switch point for haemostasis and thrombus formation. This new finding could have great clinical potential. When our blood vessels are injured by cuts, abrasions, or bruises, it is vital that the bleeding is stopped, and the wound is sealed. This process is called hemostasis and involves two main components: First, blood platelets attach to the wound edges, form a plug and provisionally seal the injury.
Intestinal bacteria are often the trigger of complications after surgery. This is shown in a new study by research teams from Würzburg and Bern. A solution to this problem could come from the liver. Nearly 16 million operations were performed on inpatients in German hospitals in 2021. In Switzerland, the figure is around 1.1 million.
Researchers from the Universities of Bonn and Michigan analyze the genome of a drought-tolerant plant Some plants can survive months without water, only to turn green again after a brief downpour. A recent study by the Universities of Bonn and Michigan shows that this is not due to a "miracle gene." Rather, this ability is a consequence of a whole network of genes, almost all of which are also present in more vulnerable varieties.
RWTH research team creates the world’s first non-spherical microbubbles
Anisotropic microbubbles open up forward-looking possibilities for ultrasound imaging and drug delivery . An international research team led by Anshuman Dasgupta and Twan Lammers from the Institute for Experimental Molecular Imaging at RWTH Aachen University has succeeded for the first time in generating stable non-spherical microbubbles.

Scientists have sequenced the composer's genome using five genetically matching hair locks The study shows Beethoven was predisposed to liver disease, and infected with Hepatitis B, which - combined with his alcohol consumption - may have contributed to his death. Furthermore, DNA from modern relatives points to an extramarital 'event' in Beethoven's paternal line.
Why we can't keep our hands off candy bars and co. Chocolate bars, potato chips and chips - why can't we just leave them to the left in the supermarket? Researchers at the Max Planck Institute for Metabolic Research in Cologne, Germany, in collaboration with Yale University, have now shown that foods with a high fat and sugar content change our brain: If we regularly eat even small amounts of them, the brain learns to want to continue consuming precisely these foods.
Water is one of the essential resources of all life. Ensuring that all people have access to clean drinking water and safeguarding its quality is not just a task for politicians. Scientists like Prof. Pu Li, head of the Process Optimization Group at the TU Ilmenau, also make an important contribution to our water supply with their research.
International team of scientists deciphers renowned composer's genome from locks of hair Ludwig van Beethoven's genome has been sequenced for the first time by an international team of scientists with the participation of the University of Bonn using five genetically matching locks of the well-known composer's hair.
Researchers from the Cluster of Excellence ct.qmat have achieved a significant milestone in the pursuit of energy-efficient quantum technologies by designing a ferromagnetic topological insulator. In 2019, an international research team headed by materials chemist Anna Isaeva, at that time a junior professor at ct.qmat (Complexity and Topology in Quantum Matter), caused a stir by fabricating the world's first antiferromagnetic topological insulator - manganese bismuth telluride (MnBi 2 Te4).
Study by the University of Bonn could lead to therapies against skin and intestinal diseases in the medium term Researchers at the Universities of Bonn and Singapore have discovered a new intracellular "smoke detector." The sensor warns of damage to the mitochondria - the microscopic power plants that supply the cell with energy.
The Würzburg-Dresden Cluster of Excellence ct.qmat has designed a ferromagnetic topological insulator - a milestone on the way to energy-efficient quantum technologies. Back in 2019, an international research team led by materials chemist Anna Isaeva - then a junior professor at the Würzburg-Dresden Cluster of Excellence ct.qmat - Complexity and Topology in Quantum Materials - achieved a minor sensation with the fabrication of the first antiferromagnetic topological insulator manganese bismuth telluride (MnBi 2 Te4).
Synthesis gas and battery power from sunlight energy Plants use photosynthesis to harvest energy from sunlight. Now researchers at the Technical University of Munich (TUM) have applied this principle as the basis for developing new sustainable processes which in the future may produce syngas (synthetic gas) for the large-scale chemical industry and be able to charge batteries.
Effective drugs against viral diseases like COVID-19 are urgently needed now and in the future. The emergence of viral mutants and yet unknown viruses could push vaccines to their limits. The DZIF scientist and bioinformatician Andreas Dräger from the University of Tübingen is working on a computer-based method that can help to accelerate the time-consuming identification and development of antiviral agents.
In pulmonary arterial hypertension (PAH), the small vessels in the lungs become increasingly narrow and obstruct the transport of blood to the lungs. A new drug can stop this change and possibly even reverse it. Pulmonary arterial hypertension (PAH) is a special form of pulmonary hypertension. It occurs because the small arteries in the lungs narrow as a result of progressive changes in the blood vessels.
An Egyptian-German research team has uncovered yet another series of colorful ceiling paintings at the Temple of Esna in Upper Egypt. The researchers reported that the Egyptian restoration team, led by Ahmed Emam, succeeded in completely restoring and re-coloring a representation of the heavens. The images, executed in relief, include a complete depiction of the signs of the zodiac.
Unique Cooperation between LG Energy Solution, MEET Battery Research Center and Helmholtz Institute Münster Since the middle of last year, MEET Battery Research Center at the University of Münster and Helmholtz Institute Münster (HI MS) of Forschungszentrum Jülich cooperate with LG Energy Solution (LGES), a leading international manufacturer of battery cells.
Study by the University of Bonn identifies different types of so-called lysosomes "Miniature shredders" are at work in each cell, disassembling and recycling cell components that are defective or no longer required. The exact structure of these shredders differs from cell type to cell type, a study by the University of Bonn now shows.
How can people be prevented from being affected again after a stroke? In order to find new therapeutic approaches for prevention, the international CRESCENDO consortium led by the MHH is conducting research at the molecular level. In Germany, 270,000 people suffer a stroke every year. This can result in severe disabilities: Paralysis, speech disorders and problems walking.
According to a new study, bees have a map-like landscape memory and are able to fly from any location to a place indicated in their tail dance. The research team's findings, which have now been published, provide a completely new assessment of the information content of the bees' so-called tail dance.
