Big Data, Big Impact: Meet Three NLM-Funded Researchers Who Are Expanding Data Availability
Advancements in AI and machine learning can shape how we can tackle “big” data challenges in biomedical discovery. See how three NLM-funded researchers are taking this on… and what their innovative work and collaboration means for clinical insights, biomechanics, and medical imaging interpretation.
Now Available: Assembled Genomes for Influenza Viruses and Improved Functionality of NCBI Virus
NCBI Virus now offers genomes for viruses such as Influenza A by using an automated process to group segments from the same samples. We group these segments into genomes based on metadata for the sample including species, isolate name, host organism, collection date, and location. Newly released GenBank records are added daily. Access these genome … Continue reading Now Available: Assembled Genomes for Influenza Viruses and Improved Functionality of NCBI Virus
