Discovery of potent inhibitors of rumen methane metabolism via an AI-assisted workflow
Researchers screened about 23 million molecules, tested 26 and found 4 active; the best cut methane by 73–98% in rumen samples from four ruminant sources in the laboratory.

Bottleneck: Cutting cattle methane without harming animals Progress
The story in three lines
- Key finding
- An AI screen of about 23 million molecules gave four active compounds that cut rumen methane by 73–98% in laboratory tests.
- Significance
- Technical: AI shortlisting turned a huge chemical space into a handful of lab-confirmed leads for livestock emissions.
- Takeaway
- Promising lab results; animal trials, safety and effects on milk and growth are still needed.
