    Cancer nanotherapy suffers from low-yield delivery that is imposed by tumour pathophysiological barriers. Top-down drug delivery strategies, including exosomes and cell membrane-coated particles, can improve safety and efficacy owing to the innate biointerfacial properties of these platforms. Here, we discuss the technological challenges that need to be overcome for their clinical implementation.

    Anticancer drugs are typically obtained through complex chemical synthesis or from plant extraction. Now, an engineered yeast strain enables a de novo biosynthetic approach to the anticancer building block catharanthine, using methanol as a carbon feedstock.

    CLASH is a CRISPR-based platform that enables the parallel knock-in via homology-directed repair of a large pool of transgene variants encoded in adeno-associated virus vectors. CLASH can be applied to the systematic and unbiased selection of favorable features in T cells and, in principle, other cell types.

    CRISPR-based assays can be adopted as ultrasensitive molecular diagnostics in resource-limited settings, but point-of-care applications must address additional requirements. Here, we discuss the major obstacles for developing these assays and offer insights into how to surmount them.
