A smile, tears in your eyes or a blush on your cheeks: we understand one another better by mirroring one another’s emotions. In her PhD dissertation, Julia Folz concludes that people with autism or social anxiety can be helped by interventions focused on the body.

A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

Bodies come in all different shapes and sizes. For his PhD, Andries Hiskes researched the disabled body and the reactions it can bring.

The Social Resilience & Security interdisciplinary programme broadens its scope by embedding two research projects lead by Dr. Joanne Mouthaan. The projects adress suicide prevention skills and mental health of Ukraine refugees. Both projects will be integrated in the programme with the aim to improve…

The fastest chemical reaction in the universe takes place inside our eyes.

Theo van den Doel received his PhD in January for his research on veteran support. This showed that for long the government learned little from past missions. He has since presented his dissertation to the Lower House of Representatives, and the Minister for Defence, Kajsa Ollongren, has responded to…

A new class of polymers has been used in patients for the first time. The compound is the first new drug solubilising agent in decades. Introduced in 2014 by chemist Matthias Barz from Leiden University, it offers a unique alternative to current options.

Een orang-oetan lacht niet gauw hard om een video waarin een soortgenoot dat ook doet. Een peuter doet het meer dan een volwassene, een Japanner weer iets minder. Chris Riddell leerde uit zijn vele experimenten ook dat geduld loont. Hij promoveert 16 september.

Biotechnological developments are moving fast. From genetically modified plant varieties we are now moving to cultured meat. These developments require moral interpretation - and they get it in the form of art. Lotte Pet wrote a dissertation about it.

Cutting down global emissions of greenhouse gases to combat global warming won’t do the trick alone: we also need negative-emissions technology that can capture carbon dioxide directly out of the air. In the prestigious journal Global Environmental Change, PhD candidate Oscar Rueda and colleagues shed…

National Meat Free Week (Nationale Week Zonder Vlees, 7–13 March) is an initiative to reduce meat consumption. Assistant professor Paul Behrens is studying what impact a change in our food consumption would have on the world. What, according to him, are the main reasons to switch to a (mainly) plant-based…

If European countries rely solely on technological advances, they won't be able to limit global heating to 1.5 degrees. Households will also need to change their lifestyles. This 'inconvenient truth' is the result of calculations done by industrial ecologist Stephanie Cap. ‘It's not a popular message,…

An international team of astronomers led by Ardjan Sturm of the Observatory has made the first two-dimensional inventory of ice in a planet-forming disk of dust and gas surrounding a young star.
