The Washington Post reports there were multiple introductions of SARS-CoV-2 into the capital region by the end of March 2020.

A composite polygenic risk score helped cluster individuals by lifespan, though it appeared to be most informative for younger individuals.

Analyzing transcriptome data from more than 1,000 cells from 74 embryos, a Johns Hopkins University-led team found aneuploid cells in 80 percent of embryos.

NPR reports that the SARS-CoV-2 genome does not appear to accumulate mutations quickly, which should help vaccine efforts.

Researchers used long-read nanopore sequencing in 100 tomato varieties to uncover more than 230,000 structural variants in the tomato genome.

In Science this week: multiple SARS-CoV-2 introductions into Northern California and the development of the 'very fast CRISPR' method.

The technique could be used to study DNA repair at high resolution in space, time, and genomic coordinates, the researchers said.
