Specialized microorganisms that are found in only one type of environment turn out to occur there in relatively low but stable numbers. Microorganisms that live in many different types of environments, on the other hand, are able to rapidly increase in numbers when conditions are favourable. Researchers from Utrecht University and the Friedrich-Schiller-Universität Jena conclude this based on a new method to distinguish generalist and specialist microbes, which they applied to a large, global dataset.

The synthetic PIC gel, discovered in 2013 by Radboud chemists, appears to behave like collagen. This makes the gel very useful for studying interactions between cells and their immediate environment. In practice, this means that the gel seems highly suitable to grow cells in for biological and clinical research.

Harm van der Veer and Maarten Merkx amongst others have developed a new bioluminescence-based sensor that can detect tiny amounts of viral or bacterial DNA/RNA in samples. PCR testing - the highly sensitive gold standard for Covid-19 detection - requires expensive equipment, expert technicians, and dedicated laboratory facilities, all leading to test times of several hours or even a day.

How do young songbirds learn to sing? To study that question properly, an international team of scientists in the Seeing Voices project have developed a singing robot that closely resembles a zebra finch.

The new state-of-the-art Ecotron module of the Netherlands Plant-Ecophenotyping Centre (NPEC) is now fully functional. The module, located in the new NPEC-dedicated building on the campus of Utrecht University, allows researchers to simulate and study agricultural and natural ecosystems. It consists of 36 enclosed units in which environmental conditions can be fully controlled and monitored.

Studying the DNA of organisms that live today can increase our understanding of how life evolved billions of years ago. For his PhD research, Julian Vosseberg delved into the DNA of contemporary organisms to find out how complex cells like those of plants, fungi and animals once evolved from simple, bacteria-like cells.

Tom van Nunen defended his thesis at the department of Electrical Engineering on February 8th, 2023. More than 43 million people worldwide are blind.

When our minds wander during performance of a task, our fine motor movements become slower, less direct and more complex. The deeper our minds wander, the more erratic our fine movements become, indicating greater detachment from the present environment. Our brains process stimuli from the external environment more weakly and brain activity becomes more similar to brain waves that are present during sleep.

Patients whose drug treatment is matched to their DNA, suffer 30 percent fewer serious side effects. This is the result from a study published by a team of international researchers, including Vera Deneer , associate professor of clinical pharmacology at the Utrecht Institute of Pharmaceutical Sciences (UIPS) and her colleague Heshu Abdullah-Koolmees , in The Lancet.

Rising sea levels, more frequent extreme precipitation and drier summers will put increasing demands on our dikes in the future. Over the next thirty years, 1,500 kilometres of dikes will need to be strengthened in the Netherlands alone. Ecologists from Radboud University and Wageningen University & Research claim that an increase in the number of flowers and herbs that are grown on dikes will already go a long way towards solving the problem.

Children born prematurely often have problems with their lungs. Can stem cells help repair their damaged lungs? Biologist Tim Wolfs is researching it with support from Longfonds (Lung Fund). The lungs of premature children are unfinished. In addition, the lungs often suffer additional damage. This can already happen during pregnancy, for example due to an infection in the amniotic fluid.

In a study published in Nature Genetics, researchers of Amsterdam UMC teamed up with colleagues from the Complex Trait Genetics department of VU Amsterdam and the Million Veteran Program to scrutinize the genetic similarity of twelve psychiatric disorders.

Biologists provide first evidence of chimpanzees communicating about a cultural practice. Chimpanzees communicate with each other to coordinate a specific type of grooming. Biologists from Utrecht University noted this behaviour using extensive video observations, making it the first reported evidence that communication and cultural behaviour are closely intertwined in chimpanzees.

Utrecht University has appointed Stefan Rüdiger as Professor of Protein Chemistry of Disease. Chemist Rüdiger and his group aim to tackle diseases that are caused by protein misfolding, such as Alzheimer's disease and Huntington's disease. They focus on how chaperones, proteins that aid other proteins to fold into their proper shape, control protein quality.

By growing in colonies of different sizes, the fungus Aspergillus niger is more effective in breaking down cellulose and more resistant to stress. Microbiologists from Utrecht University report these findings in an article in the scientific journal mBio. Aspergillus niger is widely used for the production of protein mixtures, which play an important role in the manufacturing of, for instance, biofuels or bioplastics.

Is the inside of a plant cell more like a liquid or a solid? While this may sound like an odd question, research carried out at the University of Amsterdam demonstrates it can be either, depending on how much light you shine on it. Chloroplasts within plant cells constitute an active form of matter that undergoes dramatic phase transitions.

Every human body starts out as one single cell: a fertilized egg. This cell develops into all kinds of cell types: skin cells, liver cells, blood cells. Although these cell types look and function differently, they all contain exactly the same DNA. Tuncay Baubec and his research group try to understand how the same genetic code is used to build the more than 200 different cell types in our body.

This week, the biodiversity conference takes place in Montreal, after it was postponed by Covid-19 in the Chinese city of Kunming last May. That postponement was worrying, says Professor of Land Use and Biodiversity Merel Soons , because time is running out for nature conservation. The reason our biodiversity is declining so much is well known.

Unique genetic research shows that the Ashkenazi Jewish community has been a virtually closed group since the 14th century. The international and interdisciplinary Genetic Legacies project examined DNA from the teeth of dozens of medieval and contemporary members of the community from the German city of Erfurt.

A vast amount of money is involved in Alzheimer's disease research. However, scientists have been unable to achieve substantial clinical results in recent decades. In a recent analysis of the situation, Utrecht University historian of science Bert Theunissen and his colleague from Erasmus University Rotterdam Noortje Jacobs now argue that a deadlock has developed that makes progression unlikely.
