Google DeepMind releases SynthID Bio, bringing watermarking technology to synthetic biology by embedding imperceptible signatures directly into biological code, so the watermark can be verified both on digital models and on synthesized physical proteins while preserving their biological function. The method adapts its strategy by data type: fine-tuning amino acid choices for sequences and adjusting atomic coordinates for predicted 3D structures. The team paired the AlphaProteo design method with a ProteinMPNN sequence generator with SynthID Bio, ran experiments on targets such as VEGF-A, the SARS-CoV-2 spike protein receptor-binding domain, and PD-L1, and verified through wet-lab experiments that the watermark does not impair protein function. DeepMind says this is a world first, embedding signatures into protein sequences without affecting biological function. Additionally, DeepMind discussed in a podcast the role of provenance and how imperceptible watermarks can protect digital media and biological designs.

Wiz Research 启动 Scan for Good 计划，借助 AI 加人工研究员的方式，帮助公共服务、关键基础设施和非营利组织在网络犯罪分子之前发现并修复高危暴露问题。该计划由 Google DeepMind 提供合作，并与美国网络安全和基础设施安全局（CISA）协作推进。
早期成果已验证其效果：团队通过自主运行的 AI 系统发现了大量面向公网的严重暴露，并在受影响组织的配合下完成了修复，其中一起是国家档案馆管理员密钥泄露，导致 880 万个文件面临读写删除风险。
Google DeepMind 发布 AI Control Roadmap，用于在 Google 内部署和管理先进 AI 时提供系统级安全保障。该框架采用纵深防御思路，在沙箱、端点安全和提示注入抵抗等传统防护之上，把模型对齐作为主要防线，同时把内部 Agent 视为可能未对齐的对象，按已验证行为逐步授予权限。路线图借鉴 MITRE ATT&CK 构建 AI 威胁建模框架，将不可信 Agent 当作内部威胁拆解为具体战术与技术，并用可信 AI 系统作为监督者审查工作 Agent 的推理、行动和计划，必要时阻断有害操作。
