Jongeren beïnvloeden elkaar om meer risico te nemen, al ligt dat genuanceerder dan we vaak denken. Dat ontdekte de Leidse ontwikkelingspsycholoog Jorien van Hoorn. Bovendien blijken leeftijdsgenoten elkaar ook positief te beïnvloeden. Dat is tot nu toe onderbelicht. Promotie op 12 januari.

Zonder een gewas opnieuw te zaaien toch nakomelingen produceren, die zelfs groter kunnen zijn dan de ouderplant. Volgens Leidse onderzoekers is dat mogelijk door het overstimuleren van één gen. Daarmee verjongt een cel en gaat deze terug naar de embryonale fase.

Onderzoekers moeten in een gespecialiseerde omgeving werken zodra ze aan de slag gaan met gevaarlijke bacteriën en virussen. Alleen in laboratoria met een hoog bio-veiligheidsniveau mogen ze deze microben bestuderen. Helaas zijn dure microscopen nodig om de microben goed te bekijken, maar is dat soms…
