How a researcher uses Codex and ChatGPT to search for new antimicrobial molecules

César de la Fuente’s lab uses Codex and ChatGPT to search living and extinct genomes for antimicrobial candidates to fight drug-resistant infections.

Get smart on it

A bioengineer and his lab use AI tools including Codex and ChatGPT to search through genomes of living and extinct organisms for molecules that could fight drug-resistant infections. Drug-resistant microbes pose a growing global threat, and the traditional approach of modifying existing medicines has offered diminishing returns, making the search for new antimicrobial candidates increasingly urgent. The lab treats biology as an information system, using deep-learning models to identify patterns in genetic sequences that might indicate functional antimicrobial molecules, reducing what could take years of research to just hours. Beyond their own AI models, the team uses ChatGPT and Codex to brainstorm ideas, write code, process data, and bridge knowledge gaps across different scientific disciplines, though they emphasize that AI predictions must still be validated through laboratory experiments before any molecule can become an approved drug.

Agents that build their own databases are forcing a data foundation rethink

AI agents are changing how enterprises create, move and govern information, and data observability is turning into a prerequisite rather than a nice-to-have. Models get most of the attention, but the data beneath them decides whether they hold up in production. That pressure is now reaching the cloud-native community, where KubeCon organizers added a dedicated […] The post Agents that build their own databases are forcing a data foundation rethink appeared first on SiliconANGLE.

AI agents carry memory and storage like people, so their data needs guarding while in use

As AI agents move into production on Kubernetes, cloud engineering teams at financial companies face a security problem that encryption alone can’t solve. Container orchestration has become the default foundation for AI workloads, and the data those agents use is now the main target. Payment networks feel that pressure more than most because every transaction […] The post AI agents carry memory and storage like people, so their data needs guarding while in use appeared first on Silic
