Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast.
Scientists have developed a technique that makes it possible to examine how different versions of histones bind to the genome in tens of thousands of individual cells at the same time. The technique was applied to the mouse brain and can be used to study epigenetics at a single-cell level in other complex tissues.
Synthetic biologists explored ways to fold artificial proteins into diverse shapes like origamis. They constructed diamond-shaped protein cages, and managed to transform them to different shapes.
