Proteins that play a key role in sperm motility identified using electron microscopy
Proteins that play a key role in sperm motility identified using electron microscopy
By zooming in to near-atomic level using electron microscopy, Tzviya Zeev-Ben-Mordehai and her team were able to identify the proteins that form the molecular machinery that drives sperm motility. More than twenty of these proteins were not yet recognised as part of the sperm motor apparatus, all of which are promising candidates for future research on infertility.

Eefjan Breukink appointed professor of Microbial Membranes and Antibiotics
Utrecht University has appointed chemist Eefjan Breukink as professor of Microbial Membranes and Antibiotics. Breukink and his group are engaged in research aimed at finding new antibiotics that target bacterial cell membranes, the structures that separate the inside and outside of bacteria. Breukink: "It is my dream to discover an antibiotic that will truly aid us in combating antibiotic-resistant bacteria." Cell membranes are a fundamental component of all living cells, whether they are bacterial, animal, plant, or fungal.

Effect of nitrogen deposition on animal species stronger than expected
Anthropogenic increased nitrogen deposition is a well-known environmental stressor, resulting in impoverishment of soil quality in naturally nutrient-poor ecosystems. As a result, habitat conditions for plant and animal species are also changing. Such changes are sometimes clearly visible in the field.

Wild mammals moved farther during severe COVID-19 lockdowns
Human behaviour changed dramatically during lockdowns in the first months of the COVID-19 pandemic, resulting in behavioural changes of land mammals. This is according to a study published in Science by a large international research team led by Marlee Tucker, ecologist at Radboud University. Wild mammals travelled longer distances and occurred closer to roads during strict lockdowns.

Therapy targeting specific immune cells appears promising for sepsis
Therapy targeting specific immune cells appears promising for sepsis
Nanoparticles restore balance in dysregulated immune system. Nanoparticles consisting of a designer protein that counteract an overreaction of the immune system, while simultaneously boosting that system. This invention offers possibilities for the treatment of sepsis, a condition in which the immune system is severely dysregulated.

A smart chip based on the human brain
A smart chip based on the human brain
Eveline van Doremaele received her doctorate cum laude from the Department of Mechanical Engineering on Thursday, May 25. Current computer systems are very good at performing exact calculations. But as we are using more and more AI-based applications, we also need more efficient systems that are able to process data in real time with the same precision.

Future of data storage lies in DNA microcapsules
Within five to 10 years, we will be able to store data in DNA, Professor Tom de Greef expects. Data will not be stored in zeros and ones on a hard disk, but in the base pairs AT and CG that make up DNA. In such a new DNA data centre, new files are then encoded via DNA synthesis. In another section, there are large fields of spheres: with a file packed into each sphere.

The future of data storage lies in DNA microcapsules
DNA archival storage within reach thanks to new PCR technique. Storing data in DNA sounds like science fiction, yet it lies in the near future. Professor Tom de Greef expects the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG.

Jeffrey Bajramovic: ’Het 3Rs Centrum Utrecht wil onderzoekers actief faciliteren’
Jeffrey Bajramovic is sinds juli 2022 het nieuwe hoofd van het 3Rs Centrum Utrecht (3RCU). Zijn ambitie voor het 3RCU is om een aanspreekpunt en actiecentrum voor de 3V's te worden, door informatie te centraliseren en door onderzoekers te faciliteren om nieuwe benaderingsmethoden (NAM's) op te pakken.

Jeffrey Bajramovic: ’The 3Rs Centre Utrecht aims to actively facilitate researchers’
Jeffrey Bajramovic has been the new head of the 3Rs Centre Utrecht (3RCU) since July 2022. His ambition for the 3RCU is to become an advocate and a centre of action for the 3Rs, by centralizing information and by facilitating researchers to take up new approach methods (NAMs). On 11 May, the 3RCU will organize a seminar to present Jeffrey and the plan of action for the centre.

Loops, flags and tension in DNA
Two protein complexes carry the major responsibility for the spatial organisation of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Together with Austrian colleagues, nanoscientist Cees Dekker and his PhD candidate Roman Barth of the Kavli Institute of Nanoscience at TU Delft now publish how they have visualised this in detail in Nature on April 19.

TU Delft researchers shed new light on the motor of DNA replication
DNA replication is the process whereby cells make an exact copy of their DNA before cell division. A key part of the intricate DNA replication machinery is a molecular motor called CMG, which has the vital task of separating the two strands of the DNA double helix so that they can be copied. An interdisciplinary team of researchers from TU Delft has now developed a new methodology to assemble and image the motion of CMG with unprecedented resolution.

Even in their own environment, specialist microbes are dominated by generalists
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.

Growing cells on synthetic PIC gel could save millions of mice
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.

A new rapid 'glow-in-the-dark' test for infectious diseases
A new rapid ’glow-in-the-dark’ test for infectious diseases
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.

Contemporary DNA reveals how life became much more complex two billion years ago
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.
