Cancer chess: molecular insights into PARP inhibitor resistance
The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

Vuurgebruik van onze voorouders beter te verklaren dankzij nieuwe techniek
Het gebruik van vuur kan veel vertellen over de evolutie van de mens. Archeoloog Femke Reidsma ontwikkelde een techniek waarmee nauwkeuriger kan worden achterhaald hoe onze voorouders vuur gebruikten. Bestaande archeologische studies moeten hierdoor worden herzien. De studie van Reidsma is 2 november…
