The JEFF Official Releases page is a public portal for the NEA GitLab Joint Evaluated Fission and Fusion Library. It provides links to evaluated and processed nuclear data files developed on the NEA GitLab, including the JEFF-4.0 library released in June 2025 and older JEFF data libraries released between 1986 and 2017. Restricted content is hosted on GitLab repositories and data pipelines.
The Johns Hopkins Turbulence Database is a portal to an open numerical turbulence laboratory. It provides access to multi-terabyte turbulence databases stored in small 3D sub-cubes on distributed nodes, queried through web service interfaces. Python, Matlab, Fortran and C interfaces are offered, and data subsets can be downloaded in hdf5 format. Manual point queries are supported in a web browser.

JASPAR is an open-access database of curated, non-redundant transcription factor binding profiles from six taxonomic groups. It stores manually curated binding preferences as position frequency matrices that can be converted into models for scanning DNA sequences and predicting transcription factor binding sites. From 2026 it also stores deep learning models and discovered position frequency matrices linked to its PFM collections.

The IUCN Red List of Threatened Species is a source of information on the global conservation status of animal, fungi and plant species used to inform biodiversity conservation and policy. The extract states the list divides species into nine categories, including Not Evaluated and Data Deficient.
IUBio Archive is an archive of biology data and software established in 1989 to promote public access to freely available information, primarily in molecular biology and bioinformatics. It offers ways to browse, search and fetch molecular data, software, biology news and documents, plus links to remote sources. In 2019 it was archived at Jetstream-cloud.org and Cloud.Google.com.
IU DataCORE is an open-access institutional data repository for sharing, long-term preservation and discovery of research data from Indiana University researchers. Submitting datasets requires permissions obtained by contacting IU Libraries Research Data Services.
The Integrated Taxonomic Information System is a partnership that assembles scientific names and taxonomic relationships for species across all seven kingdoms of life. It distributes this taxonomic data openly through publicly available software, including web services and database downloads. A Taxonomic Workbench is available to partners who maintain taxonomic groups.
