Swallowing triggers a feeling of elation
Life Sciences - Sep 13
A study carried out at the University of Bonn identifies a control circuit in flies essential for the consumption of food. Researchers at the University of Bonn and the University of Cambridge have identified an important control circuit involved in the eating process. The study has revealed that fly larvae have special sensors, or receptors, in their esophagus that are triggered as soon as the animal swallows something.

Power-to-vitamins: microbes produce folate from simple basic ingredients
Take some carbon dioxide, hydrogen, and oxygen plus electricity from renewable sources - a bacterium and baker's yeast need little more to produce proteins for human nourishment and the essential vitamin B9 in a conventional laboratory bioreactor system.

Greenwashing in food labelling
Researchers at Göttingen University find climate traffic light system prevents consumer deception. A research team led by the University of Göttingen found that the label 'climate neutral' makes food appear significantly more climate-friendly than it actually is.

It takes a lot of helpers to build up the protein complexes required for photosynthesis and to constantly repair them in strong light. Photosynthesis takes place before our eyes every day in every single little green leaf - yet the details of the complex process have not yet been fully understood. A research team at Ruhr University Bochum headed by Professor Danja Schünemann has unravelled another piece of the puzzle.

Researchers at Göttingen University find climate traffic light system prevents consumer deception A research team led by the University of Göttingen found that the label 'climate neutral' makes food appear significantly more climate-friendly than it actually is. Even when information about how the damage to the climate is being offset was explained, this did not stop consumers having the wrong perception about the product.

Take some carbon dioxide, hydrogen, and oxygen plus electricity from renewable sources - a bacterium and baker's yeast need little more to produce proteins for human nourishment and the essential vitamin B9 in a conventional laboratory bioreactor system. This was the result achieved by a research team led by Professor Lars Angenent from Environmental Biotechnology at the University of Tübingen during the further development of his power-to-protein system.

Bonn researchers clarify the function of specialized nerve cells in memory formation Specialized nerve cells in the temporal lobe react highly selectively to images and names of a single person or specific objects. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have provided direct evidence for the first time that the so-called concept neurons are indeed the building blocks of our memory for experiences.

An international research team has decoded the genome of the longest-lived known vertebrate: the Greenland shark. It is huge and has special repair capabilities. The Greenland Shark ( Somniosus microcephalus ), an elusive dweller of the depths of the northern Atlantic and the Arctic Ocean, is the world's longest-living vertebrate, with an estimated lifespan of about 400 years.

Information in the brain is transmitted via electrical signals between specialized cells called neurons. The activity within a large network of such neurons controls sensations, behavior, and cognition. Scientists have long sought ways to simulate the neural networks in the brain with computers in order to understand how it works.

A research team of scientists from Freie Universität Berlin and Princeton University provide insights into the origins of complete metamorphosis in insects More than sixty percent of all'animal species are insects. The majority of these species undergo complete metamorphosis, whereby the larva transforms into a pupa and then an adult.

A team of researchers from Jena and Ulm have developed an innovative approach to precisely influence the properties of light-absorbing materials, so-called chromophores. They focused on specific iron compounds, demonstrating that small changes in their chemical structure can control how these compounds react to light.

Physicists from Würzburg present a nanometre-sized light antenna with electrically modulated surface properties - a breakthrough that could pave the way for faster computer chips. Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz - which corresponds to several billion computing operations per second.

Interdisciplinary research team uses DNA microbeads to control the development of cultivated tissue A new molecular engineering technique can precisely influence the development of organoids. Microbeads made of specifically folded DNA are used to release growth factors or other signal molecules inside the tissue structures.

Dangerous mixtures: pesticides in combination can have unexpected effects on the development of honeybees. This is shown by a new study from the Biocenter. Honeybees are social insects. Their colony only survives as a community, and healthy new generations are very important. It is therefore not surprising that honeybees invest significant care and resources into their offspring: nurse bees feed the young larvae with a food juice made from nectar and pollen which they produce in a gland in their head.

Researchers from the Max Planck Institute for Marine Microbiology in Bremen, Germany, now reveal how a bacterial parasite infects and reproduces in the nuclei of deep-sea mussels from hydrothermal vents and cold seeps. A single bacterial cell invades the mussel's nucleus where it reproduces to over 80,000 cells, while ensuring that its host cell stays alive.

Numerous studies have shown that the older the father, the higher the risk of disease for the offspring. Human geneticists at the University of Würzburg have now taken a closer look at the processes responsible for this. SPIEGEL writes about "Old fathers being a risk factor", "Late fathers have more sick children" is the headline in WELT.

Language improves learning in artificial networks
Bonn researchers get to the bottom of the social aspect of communication for mental activity Across all species, critical skills are passed on from parents to offspring through communication. Researchers at the University Hospital Bonn (UKB) and the Researchers at the University of Bonn showed that effective communication relies on how both the sender and receiver represent information.

Bright yellow deposits in Consus Crater bear witness to dwarf planet Ceres' cryovolcanic past - and revive the debate about its place of origin. The dwarf planet Ceres has a diameter of almost 1000 kilometres and is located in the asteroid belt. In the television series -The Expanse-, Ceres gained new fame as the main base of the so called -belters-: in this series, which is based on real physics, humans colonize the asteroid belt for mining.

Bonn researchers find causative mutations in the keratin 31 gene for the dominantly-inherited form of monilethrix From infancy and usually for life, some families suffer from broken hair due to a congenital form of hair loss called monilethrix. Researchers at the University Hospital Bonn and the University of Bonn have now identified causative mutations in another keratin gene, KRT31.
