A potential solution to speeding up the diagnostics of coronavirus may have presented itself in the form of the gene editing molecular tool called CRISPR. Combined with high-scale advances in automation and computation, CRISPR promises to be a real game-changer in the field of synthetic biology, impacting everything from chemicals and materials to food and health. CRISPR’s precision has an uncanny ability to find a specific sequence within a sample, and one startup has a way to test for coronavirus in 30 minutes (the whole process including sample preparation will take about 4 hours).

How many newspaper stories, magazine features and TV segments have been produced so far that marvel at the revolutionary capabilities of CRISPR while giving almost no idea at all how the gene-editing discovery actually works? Those who lament the state of science journalism should take note of 'Human Nature', in which Adam Bolt and helpful scientists offer an easily understood introduction to techniques often described with head-scratching phrases like "it's a word processor for DNA!" A cogent, wide-ranging look at both the discovery and the nascent, soon-to-be-giant fights humans are having over it, the documentary should be welcomed in its limited theatrical release and will be even more useful on video.

Guided by CRISPR pioneer Jennifer Doudna, a formidable entrepreneur in her own right, C&EN profiled 15 women working in the Chemical industry in academics and startups in C&EN's 2020 Trailblazers. Four of them are affiliated with UC Berkeley's College of Chemistry. They have collectively launched more than 30 start-ups aimed at developing treatments for rare diseases, building better batteries, and more. They’re chemical scientists at the top of their game. They’re role models building and mentoring teams. And yes, they’re badasses. They live by the motto “Nobody ever got anywhere by listening to no.”

Biological membranes, such as the "walls" of most types of living cells, primarily consist of a double layer of lipids, or "lipid bilayer," that forms the structure, and a variety of embedded and attached proteins with highly specialized functions, including proteins that rapidly and selectively transport ions and molecules in and out of the cell. Scientists have long sought to develop synthetic membranes that could match the selectivity and high-speed transport offered by their natural counterparts. Now a team led by University of California Berkeley researchers has designed a novel polymer that is as effective as natural proteins in transporting protons through a membrane. The results of their research were published in Nature.
