Models of complete, day 14 human embryos grown from stem cells
Models of complete, day 14 human embryos grown from stem cells
A research team headed by Prof. Jacob Hanna at the Weizmann Institute of Science has created complete models of human embryos from stem cells cultured in the lab - and managed to grow them outside the womb up to day 14. As reported in Nature , these stem-cell embryo models had all the structures and compartments characteristic of this stage, including the placenta, yolk sac, chorionic sac and other external tissues that ensure the models' dynamic and adequate growth.

Underground amphibians evolved worldwide immunity to snake venom
Frogs, toads and salamanders are fairly common sight in our gardens, forests and ponds. However, the chance that you ever encountered a caecilian is much smaller. These mysterious animals only live in tropical regions such as Southeast Asia, Africa and the Amazon rainforest. Like other amphibians, amphibians are vertebrates.

A key to detecting Alzheimer’s with certainty
For years, scientists trying to gain a better understanding of Alzheimer's disease or other neurodegenerative disorders - tauopathies, since they involve the tau protein - have come up against one difficulty: how to diagnose the disease - beforehand - in a completely reliable way, since only autopsy today enables us to describe the tau protein aggregates in the brain, and thus to know with certainty what type of neurodegenerative disease the person was suffering from.

KU Leuven research generates new insights into the development and care for ’the little brain’ of the gut
Loss of nerve cells is a process that can take place not only in the brain, but also in the (less well-known) nervous system in the gut. A new study, carried out at KU Leuven and published in Nature , shows that specialised immune cells shape this nervous system, enabling the gut to make the transition to solid food early in life.

VUB PhD research: early microbial ancestor of humans loved extremes and can teach us about origin of life on Earth
Archaea, representing a group of primordial microbes which were recently found to be very related to humans, often grow best in extreme environments. While many bacteria (which are standing very far from us from a evolutionary point of view) can withstand only small fluctuations in temperature and acidity, Archaea are true survival champions.

How genes, brain characteristics and intelligence are connected
Genes influence different structures and the function of the brain. These in turn explain differences in behaviour. Analysing all three aspects at once is a challenge - and has been achieved for the first time. Intelligence is partly heritable. There are studies that show that certain genetic variations are linked to better performance in intelligence tests.

A pain is coming? Uncertainty intensifies brain activity and influences perception
A pain is coming? Uncertainty intensifies brain activity and influences perception
The perception of pain is a crucial signal that allows us to protect our body integrity. On the other hand, when a pain persists over time, the brain must learn to predict its evolution in order to limit the risk of injury. A team of scientists from the Institute of Neuroscience of the UCLouvain (IoNS), Prof. André Mouraux and Dounia Mulders , FNRS research fellow, together with their colleagues Ben Seymour (University of Oxford, UK) and Flavia Mancini (University of Cambridge, UK) are trying to understand these prediction mechanisms.

Same body, different engine: identical butterfly species shed new light on evolution
Same body, different engine: identical butterfly species shed new light on evolution
In Central and South America live two different species of butterflies with identically the same pattern on their wings. Eleven million years ago, the two species each went their separate evolutionary paths, eventually arriving at the same solution to deter their natural enemies: a color pattern on their wings that to birds is equivalent to "I'm not a tasty morsel.

KU Leuven researchers put octopus brain on the map
KU Leuven researchers put octopus brain on the map
Wide variation in brain cells makes octopus brain even more complex than thought For the first time, researchers are mapping the different cell types found in octopus brains. Because of these animals' amazing ability to think, it should come as no surprise that their brain cells exhibit similar properties to the known neurons and glia in other animals.

Active lipids enable intelligent swimming under nutrient limitation
Biophysicists from the University of Luxembourg have uncovered how microplankton - key photosynthetic organisms which produce nearly 50% of the oxygen we breathe - adopt a thrifty lifestyle when nutrients turn limiting. They strategically harness internal lipids to regulate swimming properties to maximise their fitness.

Study maps how brain reacts to infections
Study maps how brain reacts to infections
A team led by Prof Kiavash Movahedi (VUB, VIB) has mapped in detail how the immune system acts against pathogens invading the brain. The findings shed new light on host-pathogen interactions and the long-term consequences of brain infections. The results, published in the renowned journal Immunity, show how different types of immune cells are involved in the defence against brain infections.

Biologists create new human cell type for research
Biologists create new human cell type for research
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 .

Yellow color provides more efficient mating in locust swarm
Yellow color provides more efficient mating in locust swarm
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.

Discovery of a genetic factor that quadruples the risk of end-stage renal failure!
Discovery of a genetic factor that quadruples the risk of end-stage renal failure!
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.

The black box behind embryonic development
The black box behind embryonic development
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.
