Q&A: What if Immune Cells Don’t Actually Detect Viruses and Bacteria?

The Scientist spoke with Jonathan Kagan about his idea that immune cells respond to “errors” made by unsuccessful pathogens, not the pathogens themselves.

Scrubbing human sequence contamination from Sequence Read Archive (SRA) submissions

Do you work with human-derived sequence data? Do you often struggle with the need to determine if your data is free of human sequence and therefore suitable for public distribution? We encourage submitters to screen for and remove contaminating human reads from data files prior to submission to SRA. To support investigators in this effort, … Continue reading Scrubbing human sequence contamination from Sequence Read Archive (SRA) submissions

ClinVar to offer improved support for somatic data

We need your input!  ClinVar is NCBI’s archive of reports of the relationships among human genetic variations and diseases, with supporting evidence. To make ClinVar data more accurate and useful, we are introducing an enhanced data model to better accept and support classifications of somatic variants.  How you can help  Do you have somatic variant … Continue reading ClinVar to offer improved support for somatic data

Working to Innovate the Future of Work

NIH leadership recently gathered for its annual planning and evaluation retreat, and for the first time since late 2019, we all sat together in one large room. I cannot capture in words how inspiring and energizing it was to be together—but let me tell you, it really was! Through masks and with appropriate physical distancing, … Continue reading Working to Innovate the Future of Work
