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,…

Bullying, abuse or a difficult divorce: many young people struggle with mental health problems after traumatic experiences. But why do some suffer much more than others? This is the question that Hannah Dorsman is exploring within the THRIVE project.

If an echo (or ultrasound) shows that a foetus has a heart or other defect, parents face difficult decisions. Then an idea of their child’s shorter and longer-term future is literally a matter of life and death. Haak will argue in her inaugural lecture that the cohort studies of rare diseases that are…

Sometimes an idea seems so logical and elegant at first glance, that you later wonder why no one thought of it before. Two researchers from LACDR have teamed up to develop a completely synthetic alternative to antibodies—one that mimics their size, shape and function, but which is cheaper, more stable,…
