The most commonly used method for the taxonomic identification of tree trunks is wood anatomy. The number of experts in this area is decreasing, and education to become an wood anatomists takes many years. With the help of technology computer scientists of the Leiden Institute of Advanced Computer Science…

If a pill containing no active ingredients still helps, this positive expectation is called a placebo effect. A negative expectation is called a nocebo effect. Both can be produced by verbal suggestions and conditioning. According to Andrea Evers’ research group, combining these is the most promising…

Heavy rainfall can cause streets to flood and basements and tunnels to overflow. Jan van Rijn investigated, together with Christiaan Lamers (formerly of Leiden University) and Ton Beenen (STOWA, RIONED), how data science can help to predict which areas are at greater risk of flooding. Van Rijn presented…
