Compared to its predecessors, the Telomere-to-Telomere CHM13 genome adds nearly 200 million base pairs of sequence, corrects thousands of structural errors, and unlocks the most complex regions of the human genome for clinical and functional study. We show

Federal Research Priorities to Support Wastewater Surveillance for SARS-CoV-2

March 30, 2022

Sally Gutierrez, Nancy Lin, Jessica Sweeney

Almost immediately after the start of the COVID-19 pandemic in 2020, researchers and wastewater utilities around the world began analyzing untreated wastewater for the SARS-CoV-2 RNA. These efforts were largely based on prior experience analyzing
