Psychedelic drugs like magic mushrooms and LSD are embraced by some and seen as lethal by others. Cognitive psychologist Michiel van Elk delved into the world of psychedelic drugs and wrote a surprisingly sober book about them. ‘Without first-hand experience my story wouldn’t be complete.’

The fact that scientists are increasingly better able to access molecular cell and tissue data also brings with it a new challenge: how can scientists find the information they need for research among the vast amount of data available?

Teaching people to recognize subtle, real-world expressions will help them understand and trust others better. The aim of Mariska Kret is to develop an interactive virtual-reality training tool (E-VIRT) for a broad group of users, including patients. Kret provides a brief description of her idea for…
