When the brain causes stomach pain
The connection between brain and intestines: How stress and depression can affect gut health.
Reforestation under the sea
Seagrass is among the most important marine plants, as it harbors whole ecosystems and also stores carbon dioxide. Areas in which these underwater meadows grow have declined drastically, US scientists started a reforestation campaign, to give endangered species a new habitat and to fight climate crisis.
Broad beans support bumblebee population
Bumblebees benefit from broad bean plants. By planting these crops, the declining bumblebee population can be increased again.

Eyesight generated in the petri-dish
Scientists restore light perception of blind mice by transplanting light sensing cells, which they made from skin.
Winners of climate crisis!?
While polar bears and seals continuously struggle to survive with reduced extents of sea ice in the Arctic, penguins in the Antarctic have higher hunting and breeding success, when there is less ice.
Mouse mother’s diet influences adult offspring’s weight
A dietary study on pregnant mice shows how fiber consumption influences the metabolic development of their offspring, thus determining their health and weight as adults. These findings could apply to humans as well.
PhD student: “I feel stupid for not knowing more”
PhD student Heidemeyer suffers from imposter syndrome: ‘I am afraid that people will think that I am not smart enough’. She opens up about her experiences.
Inheritance of trauma
Trauma can have long lasting effects on a person’s psyche, but it can also change their genetic material. This way, trauma is inheritable and makes the generations to follow more susceptible for disease and mental disorders.
Research on golden poop for golden doog food
The poop of a dog says a lot about the quality of the food it is eating. In order to produce gold standard pet food, scientists analyze doog poop.
Fish change rapidly through cave life
Fish living in dark caves have rapidly adapted to their environment during evolution. New research shows that some of those changes occur within two years, without mutations to the DNA.
The link between motivation and biochemistry allows for lifelong learning
The ability to learn does not stop with childhood. It is possible to acquire new skills with motivation, even in old age, brain researchers report.
Fluorescent beads show the structure of food
Researchers have developed a method that determines the structure of foodstuffs at a molecular level with the help of tiny fluorescent beads.
First lure, then kill: beating the malaria mosquito
A new malaria control method focuses on female mosquitoes and her eggs.
Sun cream for trees?!
Last month, in the Dutch town of Doetinchem, nature managers applied sun cream onto the bark of beech trees. Is that really necessary?
Sleep study on fruit flies helps to understand brain development
The brains of adolescent fruit flies are wired to make them sleep longer than adults, which is important for brain development. Scientists believe that human brains work similarly and that this is the reason why children and teenagers sleep longer.
Are 5 servings of fruits and vegetables a day really necessary?
The body needs vitamins and minerals to carry out many vital processes. We therefore must eat them regularly, but in which quantities?
Exposed – the imposter syndrome
Do you know that feeling that everyone around you knows exactly what they are doing, while you’re just muddling on? Many people, in all kinds of professions, suffer from this so-called imposter syndrome. Even scientists, and especially PhD students, struggle with this.
Corona virus crisis: necessity is the mother of invention
Time pressure for the development of a corona virus vaccine makes researchers utilize new techniques. These promise shorter production times. But how will scientists know whether they are affective?

From fundamental research to an application
Are honey and maple syrup healthy replacements for refined sugars?
Studies have shown that natural sweeteners (honey and maple syrup) interfere less with our blood glucose levels than refined sugar. They are thus considered to be healthy. However, this is only a small piece in the puzzle of nutritional science, the overall picture looks a little different.
The latest news in Alzheimer’s research
Methods that allow an early diagnosis of Alzheimer’s disease are as important as a good therapy
Viruses as ally? Are they going to optimize our gut flora?
Both good and bad bacteria in our gut affect our health. Can’t we kill those bad bacteria?

Why scientists need to create GMOs for their research in the lab
Genetically modified organisms (GMOs) are powerful tools that help scientists study the foundation of life. The knowledge that can be created with them is the basis for applications everyone can benefit from. It can be the cure of a disease or the cure of hunger. The GMOs are made to be used in a laboratory,…
