OpenAI opens Codex Security in research preview

OpenAI says Codex Security can connect to GitHub repositories, build a codebase-specific threat model, validate suspected vulnerabilities in an isolated environment, and generate patch suggestions for human review. The bigger signal is that coding assistants are starting to become end-to-end defensive security workflows rather than just code-generation tools.

Google DeepMind launches Weather Lab public preview

Google DeepMind and Google Research launched a public preview of Weather Lab, an interactive site for sharing AI weather models, and introduced a new experimental cyclone-prediction system. That matters because it puts model outputs closer to operational users like weather agencies and emergency services, not just research audiences.

NVIDIA reframes agent training around “intelligence per dollar”

NVIDIA’s latest Vera Rubin messaging argues that continuous post-training for agents — especially reinforcement-learning rollouts tied to real deployment feedback — is becoming a central compute workload of the agentic era. The interesting strategic point is the shift from optimizing one-time training milestones to optimizing nonstop improvement loops.

Qualcomm pushes on-device AI into worker-safety monitoring

Qualcomm highlighted an industrial worker-safety system that uses on-device AI to detect missing personal protective equipment, unsafe behavior, and restricted-zone entry in real time. This is the kind of edge deployment that makes practical sense for factories and job sites because it combines low latency with tighter data locality.

Starlink said its high-speed, low-latency satellite internet service is now available in Seychelles. Even when the country is small, these rollout announcements matter because they show the LEO broadband map filling in through steady operational expansion rather than just headline-grabbing launches.

TSMC raises its AI-driven outlook and deepens U.S. expansion

TSMC raised its annual revenue forecast after reporting record profits tied to AI demand and said it plans another $100 billion of U.S. manufacturing investment, bringing total pledged U.S. spending far higher. For the broader ecosystem, this is a strong indicator that AI demand is still translating into real foundry capex and supply-chain buildout.

Robust Design of Integrated Sensing and Communication in LEO Satellite Systems

Authors: Hezhen Yang, Xiaoming Chen, Qi Wang
Venue: arXiv
This paper studies robust ISAC design for LEO satellite systems under constrained shared wireless resources, which is directly relevant to future NTN architectures that need to juggle sensing and communications together.

MIT / Harvard Events This Week

Source Issues

  • TNT’s calendar fetch exposed only sparse text and a past FOUNDAHFEST entry, so dated event listings were taken from MIT and Harvard official pages.
  • Ericsson’s official article path was access-restricted in this environment, so that item was dropped instead of using a weaker secondary source.
  • IEEE and ACM did not surface stronger fresh wireless papers than the same-week arXiv submissions selected above.

Takeaway

The clearest theme today is operationalization: AI is moving deeper into security, weather, industrial monitoring, and semiconductor investment decisions while connectivity infrastructure keeps widening in parallel.
