An inherited genetic mutation may increase lung cancer risk among people who have never smoked, with carriers of the rare EGFR T790M variant facing roughly 25 times the risk of lung cancer overall and 62 times the risk among never-smokers, according to a new study in Science. scim.ag/4yDSuP2

What can we learn about a single rare variant? Published today in Science: the 23andMe Research Institute and Dana-Farber studied the EGFR T790M in 10.1M 23andMe research participants. The variant has OR = 25.2 for lung cancer, rising to 61.7 in never-smokers(!). 🧵

Embracing non-linearity in human ageing
Nature Reviews Genetics, Published online: 03 August 2026; doi:10.1038/s41576-026-00993-9Ageing has often been conceptualized as a gradual, linear decline, yet growing evidence suggests it unfolds through dynamic, stage-specific transitions. In this Perspective, the authors examine such evidence across molecular and physiological systems and discuss analytical frameworks to identify non-linear transitions.

Nitric oxide drives proteomic diversity through alternative splicing
Schindler et al. report that RNA-binding proteins undergo widespread S-nitrosylation at evolutionarily conserved sites. S-nitrosylation of the master splicing regulator PTBP1 alters RNA-binding properties to reprogram the transcriptome and proteome. Nitric oxide thereby coordinates gene and protein regulation in cellular physiology and disease.
