Using Comparative Genomics to Advance Scientific Discoveries
Guest post by Valerie Schneider, PhD, staff scientist at the National Library of Medicine’s National Center for Biotechnology Information, National Institutes of Health. In a post from earlier this year, A Journey to Spur Innovation and Discovery, I shared news of an exciting NIH-supported NLM initiative, now known as the NIH Comparative Genomics Resource (CGR). … Continue reading "Using Comparative Genomics to Advance Scientific Discoveries"
The Sequence Read Archive slims down your data with SRA Lite
In response to your requests for compact and faster-to-deliver data, NIH’s Sequence Read Archive (SRA) now offers a new data format – SRA Lite (Figure 1). SRA Lite supports reliable and faster data transfer, downloads, and analysis using current tools. SRA Lite replaces the submitted base quality score (BQS) with a simplified read quality score, … Continue reading The Sequence Read Archive slims down your data with SRA Lite
COVID-19 Vaccines Protect the Family, Too
Any of the available COVID-19 vaccines offer remarkable personal protection against the coronavirus SARS-CoV-2. So, it also stands to reason that folks who are vaccinated will reduce the risk of spreading the virus to family members within their households. That protection is particularly important when not all family members can be immunized—as when there are children under age 12 or adults with immunosuppression in the home. But just how much can vaccines help to protect families from COVID-19 when only some, not all, in the household have immunity?
