Looking at toxicodynamic variation in the human population to address chemical safety
The European Food Safety Authority (EFSA) has awarded a €1.6M contract to an LACDR-led consortium to assess how sensitivity to toxicity caused by chemicals varies among individual people. Currently these toxicodynamic differences are an unknown source of uncertainty when carrying out risk assessment…

A cocktail of chemicals in surface water is more toxic than each substance individually
Pesticides can form a toxic cocktail when they occur in combination in surface water. This is the finding of research that Leiden University and the Dutch National Institute for Public Health and the Environment (RIVM) presented on Monday 14 October. The Dutch Ministry of Infrastructure and Water Management…

Sugar chemistry – Wouter Remmerswaal’s unrelenting pursuit of understanding
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.
