How star-shaped cells increase flexible learning
How star-shaped cells increase flexible learning
Bonn researchers solve the hidden mystery of the role of astrocytes for learning processes and memory in the brain Star-shaped glial cells, so-called astrocytes, are more than just a supporting cell of the brain. They are actively involved in learning processes and interact with the nerve cells. But what exactly is it that astrocytes do? Researchers at the University Hospital Bonn (UKB) and the University of Bonn are using a biophysical model to clarify how astrocytes interact with nerve cells to regulate rapid adaptation to new information.

Revealing coastal sediment pathways
Stuart Pearson, coastal engineer at TU Delft, receives a NWO Veni grant to investigate sediment pathways. He will specifically focus on tracking individual sand grains. Revealing the interconnected network of sediment pathways that shape our coast will help us to better manage the sediment that builds ecosystems and protects us against flooding.

Logged forests can still have ecological value - if not pushed too far
Logged forests can still have ecological value - if not pushed too far
Researchers have analysed data from 127 studies to reveal 'thresholds' for when logged rainforests lose the ability to sustain themselves. The results could widen the scope of which forests are considered 'worth' conserving, but also show how much logging degrades forests beyond the point of no return.

Scientists make breakthrough in development of fridge-free storage for vital medicines
Scientists make breakthrough in development of fridge-free storage for vital medicines
Scientists have developed a new approach to store and distribute crucial protein therapeutics without the need for fridges or freezers. The breakthrough, published in the journal Nature , could significantly improve accessibility of essential protein-based drugs in developing countries where cold storage infrastructure may be lacking, helping efforts to diagnose and treat more people with serious health conditions.

Researchers predict fewer, pricier strawberries as temperatures warm
Researchers predict fewer, pricier strawberries as temperatures warm
Study examined effect of rising temperatures on California's crop  Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to research from the University of Waterloo. Using a new method of analysis, the researchers found that a rise in temperature of 3 degrees Fahrenheit could reduce strawberry yields by up to 40 per cent.

Factors enabling a human RNA virus to mutate and facilitate its transmission identified
The Institute for Integrative Systems Biology (UV-CSIC) has conducted the first comprehensive analysis of all mutations in the protein set of coxsackievirus B3, which causes severe heart inflammation. The findings, published in Plos Biology, will help to identify regions of the virus genome with low tolerance to mutations, facilitating the development of drugs targeting these areas.

’Diabetes distress’ increases risk of mental health problems among young people living with type 1 diabetes
Children diagnosed with type 1 diabetes are at significantly higher risk of a number of mental health issues, including mood and anxiety disorders, a study from a team in the UK and the Czech Republic has found. We know that people diagnosed with type 1 diabetes can experience 'diabetes distress'. It's little wonder, then, that they are at risk of compounding mental health problems, spanning into their adult lives Benjamin Perry The findings highlight the urgent need for monitoring and support for the mental health of young people diagnosed with type 1 diabetes.

Powerful new particle accelerator a step closer with muon-marshalling technology
Powerful new particle accelerator a step closer with muon-marshalling technology
New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics. Particle accelerators are best known for colliding matter to probe its make-up, but they are also used for measuring the chemical structure of drugs, treating cancers, and manufacturing silicon microchips.

More vegetarian dishes on the menu: a successful experiment in university catering
Since January 1, 2023, the Egalim law has required public establishments to offer a vegetarian option every day. In line with this, the Crous are aiming for 30% vegetarian meals by 2025. One of the main obstacles to be overcome to reach this objective is the acceptability of such a measure by students.

The magnet trick: New invention makes vibrations disappear
TU Wien (Vienna) has patented a completely new method of dampening vibrations. This is an important step for precision devices such as high-performance astronomical telescopes. When everything shakes, precision is usually impossible - everybody who has ever tried to take a photo with shaky hands or make handwritten notes on a bumpy bus journey knows that.

Multiple concussions in rugby players change proteins in their blood
A new study shows that retired rugby players who have suffered multiple concussions have abnormal levels of certain proteins in their blood. This may make them more prone to developing diseases such as motor neurone disease (MND). This is what new research led by our bioscientists has found as part of the UK Rugby Health project.

'Paleolithic' diets are not without risks
’Paleolithic’ diets are not without risks
A study highlights the toxicity risks of high-protein diets, which can lead to severe neurological disorders. High-protein diets, known as ''Paleolithic diets'', are popular. Using mouse models, scientists at the University of Geneva have studied their impact. While effective in regulating weight and stabilizing diabetes, these diets are not without risks.

Combining Indigenous knowledge and deep learning to support safer on-ice travel
Combining Indigenous knowledge and deep learning to support safer on-ice travel
Warming temperatures mean shorter ice seasons for Inuit in Sanikiluaq, Nunavut. Of equal concern is the growing unpredictability of the ice packs used to travel and hunt. Small polynyas, where ocean currents, wind or other processes prevent ice from forming, can be very dangerous and must be spotted before travelling.

Key Driver for Epithelial Cancer Development Identified
Key Driver for Epithelial Cancer Development Identified
A distinct signaling pathway called TNF- drives the transformation of epithelial cells into aggressive tumor cells. During cancer progression, cells activate their own TNF- program and become invasive. This finding could help to improve early detection and treatment of patients with cancers in skin, esophagus, bladder or colon, as researchers state.
