Kilobase-scale nickase-targeting (KNIT) editing enables single-nick-based DNA insertion across genomic loci and cell types, supporting insertion of DNA fragments exceeding 10 kb, with high efficiency and minimal unwanted off-target effects.

Alkaline water electrolysers are being optimized for higher performance, but measures such as advanced electrodes or thinner separators can increase hydrogen crossover and safety risks. Here the authors analyse crossover behaviour and show that a gas recombination catalyst cuts crossover by 95% without affecting electrolyser performance.
