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.
An apple or a pill per day, which keeps the doctor away?
Vitamins and minerals are very important for our health, but it is not so easy to eat enough fruits and vegetables. Nutrient pills are a welcome alternative, but can they compensate for a balanced diet?
Decision making without a brain – The secret messengers of plants
How do you make decisions if you cannot think? How do you respond to danger if you cannot run or hide? Plants know the answer to these questions. And fundamental researchers all over the world try to understand them as well.
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.
I was wrong – online conferences
A few years ago one of my colleagues wondered why we still travel the world to attend conferences. I immediately jumped on the conversation and passionately argued that physical gatherings are necessary for science. I was completely convinced that I was right.
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?
