Hoe helpen lipasen in Mycobacterium tuberculosis de bacterie te overleven, en kunnen we deze enzymen gebruiken als doelwit voor nieuwe antibiotica?

Nog altijd lukt het niet om alle kankerpatiënten van de juiste behandeling te voorzien. Oncode Accelerator wil daarom de manier waarop we kankerbehandelingen ontwikkelen innoveren: binnen het programma wordt de patiënt centraal gesteld. Universiteit Leiden en LUMC gaan hier samen met andere partijen…

Om goed onderbouwde besluiten over complexe onderwerpen zoals het klimaat, recht en gezondheid te kunnen nemen, zijn wetenschappelijke resultaten van groot belang. Maar wetenschappelijke resultaten bevatten altijd een mate van onzekerheid. Binnen het onderzoek Communicatie over onzekerheden wordt onderzocht…

Dit zijn de mensen die binnen de Universiteit Leiden actief zijn op het gebied van kunstmatige intelligentie.

Voormalig promovendus Cameron Mackie krijgt niet één, maar twee proefschriftprijzen voor zijn proefschrift over het aromatische universum. Door zijn werk kunnen we binnenkort misschien een virtueel ‘snuifje’ van de ruimte nemen. ‘Deze moleculen in de ruimte ruiken waarschijnlijk als een grote houtsk…
