Studying how single DNA molecules behave helps us to better understand genetic disorders and design better drugs. Until now however, examining DNA molecules one-by-one was a slow process. Biophysicists from Delft University of Technology and Leiden University developed a technique that speeds up screening…

How do fats and enzymes in the brain contribute to multiple sclerosis? In his PhD research, Daan van der Vliet combined chemistry and neuroscience to gain new insights into how brain disorders develop.

Martina Huber, Jacqueline Labra Munoz research Alzheimer's disease. They study ferritine, iron storage in the brain. An inbalance of iron could play a role in this form of dementia.

The dark matter of biology: clumps of sugar molecules that, for example, form sugary webs around pathogens. We know very little about them. Wouter Remmerswaal threw all his talent into the challenge – both in the lab and as a modeller – and succeeded. He received his PhD on 12th September.

An all-optical transistor, a molecule-sized sensor and a new kind of single-photon source for quantum communication. All dreamed applications of fundamental physics that are one step closer thanks to Robert Smit. On 12 June, he defended his PhD thesis with distinction.

Why does a medicine work well for one person, but cause side effects in another? Research by Laura de Jong shows that it’s not just our DNA that matters – other medicines and illnesses can also affect how our bodies respond.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

Interview with Pieter Slaman who received the LUS Education Prize. What makes the award so special to him and does he already know how he will use his prize money?

A patent for what may be a potent, new antibiotic. And: a clear overview of promising approaches to overcome a crucial resistance tactic employed by bacteria. In the span of one week, two researchers from Leiden are receiving their PhDs, each of them on an important step in the battle against bacteria…

Autism, Alzheimer’s, and bipolar disorder: can the development of these mental health conditions be influenced by the ketogenic diet? Increasingly, research suggests it might. 'For those it helps, it can be life-changing,' says neuroscientist Eline Dekeyster.
