Chemical bond versus electromagnetic waves
Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Are autistic youngsters less prosocial?
A common notion is that autistic people feel no need for social contact, that they are socially clumsy and show little prosocial behavior. But is that image correct? According to developmental psychologist Carolien Rieffe, an important goal of Autism Awareness Week (March 28 - April 5) is to remove…

The Mystery of the Pointy Droplets
A certain type of oil droplets changes shape when cooled and shrunk: from spherical through icosahedral to flat hexagonal. Two competing theories couldn't fully explain this, but now, a Physical Review Letter by Ireth García-Aguilar and Luca Giomi solves the mystery.

Proactive personality has stronger wake-sleep rhythm
Proactive zebrafish appear to have a much stronger wake-sleep rhythm than reactive fish. In the most reactive fish, rhythmicity appears to be lacking completely. This is shown with research by Leiden biologists, published in December 2018 in the journal BMC Biology.

Research Trainee Project on Religious Narratives as Plausibility Structures launched
Religions involve belief in the unbelievable: in evil spirits causing disease, in souls surviving death, and in gods punishing wrongdoers and blessing the just. Cognitive studies suggest that humans are predisposed to speculate about fate and divine agency, but support from so-called ‘plausibility structures’…

Electrolysis and fuel production
Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

How plant-based diets not only reduce our carbon footprint, but also increase carbon capture
Almost 100 billion tons of CO₂ could be pulled out of the atmosphere by the end of the century. That is, if high-income countries switch to a plant-based diet. The double carbon profit of returning farmland to its natural state would equal about 14 years’ worth of agricultural emissions, researchers…
