Happy to see our review out! 🧬 How does ssDNA arise during DNA replication, and how can complementary approaches help us distinguish its different molecular origins and potential outcomes? www.sciencedirect.com/science/arti... So, mind the…replication-associated ssDNA (one for the UK commuters).

Replication stress in cancer: origins, consequences and therapeutic opportunities - Nature Reviews Cancer
Replication stress drives genomic instability, tumour evolution and therapeutic adaptation, yet also creates exploitable vulnerabilities. In this Review, Chen and Zou discuss how chronic replication stress shapes cancer biology and how emerging therapies are targeting the pathways that enable tumour cells to survive it.

The long return on discovery science in cancer therapeutics
Nature Reviews Cancer, Published online: 28 August 2026; doi:10.1038/s41568-026-00978-0Many advances in cancer treatment depend on discoveries made decades earlier. In this Comment, Murphy et al. discuss the histories of EGFR, HER2, CDK4/6 and RAS, highlighting how long translation can take and how clinical benefit can continue to accumulate as more effective drugs are developed, used in earlier disease settings and combined with existing treatments.

Genetically encoded manipulation of ATP/ADP ratio in human cells uncovers proteomic and physiological signatures of energy stress
Ekvik et al. genetically introduced an exogenous ATP-consuming enzyme into human cells in order to study the direct effects of energy stress in vivo. This genetic approach offers flexibility and specificity inaccessible through conventional drug-based models of energy stress. The intervention produced well-established as well as unexplored energy stress responses.
