Data Sheet 1: Developing a Standard Definition for Sequences of Concern

1.1 million sequences from pathogens, toxins, and their relatives were used to develop a biosecurity screening rubric. The rubric, refined through a stakeholder review process, categorizes sequences of concern for human pandemic-potential viruses, low-risk genes, and controlled toxins. Applying the rubric reduced disputed categorizations by 44.3% for controlled viruses in the test set.

Plasma Metabolomic and Lipidomic Profiles for Rheumatoid Arthritis Treatment Response

A study by Jiani Chen analyzed plasma samples from 106 rheumatoid arthritis patients and 10 healthy controls using liquid chromatography–mass spectrometry. The analysis tentatively annotated 2,279 metabolites and 2,987 lipids, identifying 12 core features associated with treatment non-response. Machine learning models using these features achieved area under the curve values exceeding 0.90 in internal cross-validation.

AIRS/Aqua L1B NRT: Infrared Radiances in BUFR Format

Global satellite data from the AIRS instrument on NASA's Aqua spacecraft provides near real-time, calibrated infrared radiance measurements. This dataset is a 324-channel subset of the AIRIBRAD_NRT_005 product, converted to the BUFR format and includes AMSU footprints to meet a three-hour latency requirement. It is intended for time-sensitive applications but contains a documented spectral shift for channels in the L1b v5 product following a 2021 spacecraft maneuver.
