CRISPR

Sickle cell patients such as Cassandra Trimnell and Evie James Junior and UCSF physician Mark Walters talk about the severe pain experienced by those with the disease and the potential benefits of a CRISPR cure.

In 2014, two years after her Nobel Prize-winning invention of CRISPR-Cas9 genome editing, Jennifer Doudna thought the technology was mature enough to tackle a cure for a devastating hereditary...

Scientists from the Innovative Genomics Institute (IGI), the same UC Berkeley group that rapidly popped up a state-of-the-art COVID-19 testing laboratory in March, are now trialing a quicker way to obtain patient samples: through saliva. Saliva, collected in the same way companies like 23andMe and Ancestry.com get samples for DNA genealogy analysis, can be gathered without medical supervision, and that saves time, money and precious PPE.

Markita Landry and UC Berkeley recently filed patents on a new nanotube technology to delete genes in crop plants without the risk of inserting new genes. Editing the genome of crop plants can boost such traits as disease resistance or drought tolerance. Since the new process adds no genes to the plant genome in the editing process, it conforms to non-GMO requirements in the U.S. and several other countries outside Europe.

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.
