AES-1: Bacterial Gene Expression Data from Spaceflight Antibiotic Experiment

Gene expression data from the Antibiotic Effectiveness in Space (AES-1) experiment, conducted by the National Aeronautics and Space Administration. The data provides insights into biomolecular processes behind altered bacterial behavior in microgravity, such as increased cell counts and virulence. The dataset was last updated on 2026-03-13.

Use Cases

• Modeling bacterial stress responses based on glucose starvation and acid resistance gene activation.
• Investigating the link between metabolism stimulation and increased bacterial cell concentrations in microgravity.
• Analyzing the relationship between reduced extracellular pH and increased virulence reported in space.
• Corroborating computational models of reduced mass transport effects on bacterial behavior.

Strengths

• Data originates from a controlled spaceflight experiment (AES-1) by NASA.
• Gene expression results provide direct molecular evidence for proposed physical models.
• Dataset was updated on 2026-03-13, indicating recent maintenance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• File formats include BIN and HTML, which may require specialized tools for access.
