The session aimed to find and computationally validate new antimicrobial peptides in Streptococcus pseudopneumoniae. The researcher chose which questions to ask while the AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → handled cross-database queries, structural analysis, and literature synthesis.
DeepMind is introducing a Biomolecular Structure Viewer inside Antigravity. The agent can load structures from AlphaFold Database and highlight regions, and residues or notes the researcher marks are synced back to the agent.
ProtNLM predicts protein function directly from raw amino acid sequences, which lets the search reach UniProt entries whose function is unknown because they resemble no characterized protein.
The post focuses on bacteriocins, a class of antimicrobial peptides that target basic bacterial vulnerabilities such as cell envelopes, which the authors say makes resistance hard for pathogens to develop.
