Professor Vincent Pasque and his team at KU Leuven have generated a new type of human cell in the lab using stem cells. The cells closely resemble their natural counterparts in early human embryos. As a result, researchers can now better study what happens just after an embryo implants in the womb. The findings were published in Cell Stem Cell .

In a large epidemiological study researchers from KU Leuven show that patients with an autoimmune disorder have a substantially higher risk of developing cardiovascular disease than individuals without autoimmune disease. The research shows for the first time that cardiovascular risks affect autoimmune disorders as a group of diseases with implications across a broad range of cardiovascular outcomes.

An international team of researchers led by Professor Jozef Vanden Broeck (KU Leuven) discovered why adult male desert locusts in a swarm have a yellow color, in contrast to their brownish, female counterparts. This color difference ensures that male locusts can recognize fertile females during mating in a large swarm and avoid ending up with another male or with an already formed pair.

In brief: Chronic kidney disease (CKD) affects over 10% of the world's population, including over one million people in Belgium. Genetic mutations are a major cause of CKD. Some mutations are very rare and have very severe effects on the kidney. Others are much and have barely detectable effects. For the first time, a UCLouvain team has discovered an intermediate-effect genetic mutation, present in about one in 1,000 people, that strongly increases the risk of CKD.

An international research led the VUB Biology Department examined 21 st century changes in ocean-surface temperature, salinity, and density, across mangrove forests worldwide. The study suggests that changes in surface-ocean density may impact the dispersal patterns of widely distributed mangroves species, and more likely so in the Indo-West Pacific region, the primary hotspot of mangrove diversity.

The ESA Gaia mission has released its new treasure trove of data about our home galaxy. Astronomers - including Professor Conny Aerts from KU Leuven - describe strange 'starquakes', stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date. Gaia is ESA's mission to create the most accurate and complete multi-dimensional map of the Milky Way.

A research team at KU Leuven (Belgium) has developed a new technique that allows researchers to easily quantify the concentration of calcium in living organisms over a long period of time. Up to now, this was only possible with more complex experimental setups. This simplified method can be adapted to other molecules and tissues, making it a useful instrument for translational research and the development of applications.

Stem cell biologists identify how placenta cells are regulated DNA regulation is a critical process in a cell that allows it to fulfil its function. This process is key during pregnancy, when embryonic cells must develop into all cell types needed to form an embryo. An international team of researchers from KU Leuven, Babraham Institute, Radboud University, Ghent University and IMBA, have discovered that the first cell fate decision of embryonic development is regulated by a protein known as PRC2.

Researcher Vickà Versele (VUB-KU Leuven) focuses with the TRANSPARENTS research project on the changes in body composition and lifestyle in couples having their first child. Her recent study - published in the international journal Pediatric Obesity - now shows that the lifestyle of mom and dad at the beginning of pregnancy has an impact on the weight curve during the first year of life for girls, but not for boys.

Ghent University research in Burkina Faso: fortified food supplements increase the chance of a healthier baby Every parent around the globe wishes for a healthy baby.

Thursday, May 19, 2022 — The wood wide web has been a hot topic among biologists in recent years. Trees and plants are interconnected and not only share information, they also support each other by passing on signals or food. They do this by means of mycorrhizal fungi that live in symbiosis with the roots.

A system composed of four gravitationally bound stars has been followed by spectroscopy for several years by a team of researchers. This quadruple system is unstable and simulations of its future evolution show that, eventually, the stars may collide, which is likely to produce a thermonuclear supernova.

Successful and unsuccessful approaches to the pandemic by Western governments Tuesday, May 17, 2022 — Since 2020, the world has been experiencing the consequences of the Covid-19 pandemic. The cause is obviously a virus, but the degree of its spread, and the associated number of infections and deaths, is largely dependent on socio-economic factors.

Not every type of greenery in an urban environment has the same positive effect on people. One large tree with a robust crown has more impact than ten young trees. That is the conclusion of a large-scale study by KU Leuven that was published today in the influential journal Environmental Health Perspectives.

In brief: It's a very promising world first! Scientists at University of Louvain (UCLouvain) have managed to identify the key that allows the Covid virus to attack cells Better still, they have also managed to close the lock to block the virus and prevent its interaction with the cell, in other words, to prevent infection This discovery raises a huge hope : that of developing an antiviral, in the form of an aerosol , which would help to eradicat

Antibiotics are commonly used to treat infections and ensure the safety of surgical procedures. However, their overuse has led to the emergence and spread of resistant bacteria, resulting in an -arms race- whereby ever more potent drugs are becoming a necessity.

All-Luxembourg study helps to anticipate a personal COVID-19 health trajectory From the start of the COVID-19 pandemic, the majority of published studies have focused on severe COVID-19 patients in order to understand the causes of critical illness. However, it is equally, if not more important to understand the protective immune factors in our body.

To this day, cavities and damage to enamel are repaired by dentists with the help of synthetic filling materials. There is no natural alternative to this. A new 3D model with human dental stem cells could change this in the future. The results of the research led by KU Leuven Professor Hugo Vankelecom and Professors Annelies Bronckaers and Ivo Lambrichts from UHasselt have been published in Cellular and Molecular Life Sciences .

Researchers delve into the inner workings of the antibody immune response, finding key differences in the metabolism of two closely related immune cell subsets. Protection against viral diseases is a key role of our body's immune response, where antibodies are generated to seek out invading species and either neutralise or mark them for destruction.

A new study finds that five of the largest platform companies in Belgium fail to offer fair working conditions. The Fairwork research project in Belgium,  at the Centre for Sociological Research at KU Leuven and in collaboration with the University of Oxford, rated the working conditions of Takeaway, Ring Twice, Deliveroo, Yoopies, and Top Help.
