Evolution finds shelter in small spaces.
When RNA is replicated in cell-free systems, a ubiquitous problem is the hijacking of the system by short parasitic RNA sequences. In this issue of Chemistry & Biology, Bansho et al. show that compartmentalization into water-in-oil droplets can ameliorate this problem, but only if the droplets are small. This result helps to both recapitulate abiogenesis and optimize synthetic biology.

Predetermination of sex is of commercial importance since economic value of each livestock species is different for different sex. Embryo sexing enables the producers to run a fewer recipient female and thus quickly increase the size of their herd. The widespread use of embryo transfer technology has created an alternative approach in controlling the sex of offspring. The methods used can be gr...
