science TechnologyWorld Cup questions: can statistics predict who will win the FIFA World Cup?This year, it is finally going to happen. The Netherlands will become world champion. What did not work out in 2010 will happen in 2026. At least, if we believe economist Joachim Klement. His model previously predicted the winners of the last three World Cups: Germany in 2014, France in 2018 and Argentina in 2022. For 2026, his model points to the Netherlands. Great news for Dutch football fans. But can statistics really predict who will win the biggest football tournament in the world?
science SecurityWorld Cup questions: can a stadium collapse from jumping fans?You are surrounded by 80,000 jumping and chanting fans in New York New Jersey Stadium. Whole sections of the grandstand are swaying in rhythm with the crowd. For some spectators, that movement is thrilling, for others it is unsettling, but the question is: how safe is it? “Such motion is generally harmless,” Dr Roland Kromanis, a team lead of Structural Health Monitoring for Smart Infrastructure at the University of Twente, says: “The engineering challenge isn’t to eliminate the vibrations but to ensure they remain within acceptable limits.”
science HealthKees Study: Can I get a tattoo without a needle?Around 44 million Europeans have a tattoo, and the method has barely changed in centuries. A needle punctures the skin over and over to leave ink behind. It hurts, and it damages the skin. In this Kees Study I find out if I can tattoo without a needle?
science HealthHow healthy is an e-bike?Electric bikes have made cycling easier. You are still outside. Your legs are still moving. But how healthy is riding an e-bike really? The answer is more nuanced than you might think.
science TechnologyWhy borders are less fixed than you thinkOn the map, the Netherlands seems neatly outlined. A clear border separates us from Belgium and Germany. But how did that line come about? And is it really as fixed as we think?

science HealthKees Study: My brain hacked, how brain stimulation could help with Parkinson'sImagine your hand moving without you telling it to. Not because you flinched, but because an electrical signal in your brain gave the command. That's what happens in Parkinson's disease. At the same time, electricity on the brain can also help to reduce the symptoms of Parkinson’s disease. That's exactly what researchers at the Brain Stimulation Lab of the University of Twente are trying to understand.
science ClimateOlympic questions: What makes an ice skating suit faster?Ice skating at speeds exceeding 50 kilometres per hour. How do olympians achieve that top speed on the ice? The push-off is crucial, of course, but did you know that at Olympic speeds, approximately 80 per cent of the opposing force is air resistance? In this episode of Kees Study, I dive into the wind tunnel to discover how aerodynamics can make the difference between silver and gold.
science RoboticsKees Study: How difficult is it to take a biopsy in an MRI scanner?Taking a biopsy while a patient is lying in an MRI scanner is extremely complicated. It requires extreme precision. Most robots cannot operate near an MRI scanner. In this new episode of Kees Study, I discover how medical robotics makes this possible, with a robot specially designed for MRI-guided breast biopsy.
