The Frontier
Science & tech breakthroughs in AI models, hardware, and computing that define what's possible
Researchers escaped OpenAI Codex’s sandbox to run commands on a host. Security researchers found two ways to escape OpenAI Codex’s sandbox, including a method that could execute commands on a developer’s host machine from the product’s most restricted mode. OpenAI patched both vulnerabilities after disclosure.
BragJack attacks hijack AI browser agents through malicious extensions. Forever Security researcher Gal Weizman demonstrated BragJack, a proof-of-concept attack that uses a malicious browser extension and prompt forcing to hijack AI assistants in Chrome, Edge, Opera Neon, Perplexity Comet, and Claude in Chrome. The research resulted in two CVEs and more than $20,000 in bug-bounty awards.
Scientists opened a sealed envelope after 10 years. Gravity still disagreed. A decade-long NIST experiment produced a new measurement of the universal gravitational constant, G, that differs from another leading measurement. The small mismatch extends a long-running challenge in precisely determining one of physics’ fundamental constants.
Capital & Control
Tracking the flow of capital and influence that shapes the tech landscape
The US Navy just outlined its tech wish list. Department of the Navy chief technology officer Justin Fanelli described an effort to reduce fragmented startup entry points and move suppliers through a more centralized procurement funnel. The goal is to bring companies that demonstrate results into the Navy’s technology base as enterprise-service providers.
Infrastructure & Power
The physical backbone of AI: compute, data centers, supply chains, and the geopolitics of energy
It’s Donald Trump versus MAGA on data centers. Wired reports a growing divide between President Donald Trump’s support for data-center and AI expansion and resistance from parts of his MAGA political base. The conflict centers on the local consequences of large data-center development, including the infrastructure demands tied to expanding AI computing capacity.
Digital Defense
Threats and defenses shaping the global security landscape
An undercover Google analyst infiltrated a notorious supply-chain hacking gang. Google Threat Intelligence disclosed that one of its researchers infiltrated TeamPCP during the group’s software supply-chain campaign. The group allegedly compromised developer accounts, planted malware in hundreds of open-source projects, deployed a self-propagating worm, and breached more than 1,000 companies before two alleged members were arrested in Australia.
The Performance Edge
Peak performance science for sustained execution in high-stakes environments
Eight common food additives are linked to high blood pressure and heart disease. A study published in the European Heart Journal linked higher consumption of eight commonly used food preservatives with elevated rates of hypertension and cardiovascular disease. The observational research does not establish that the preservatives caused the outcomes, but it adds evidence on processed-food exposure and cardiometabolic risk.
Crypto & Digital Assets
Bitcoin, Ethereum, DeFi protocols, and digital asset market dynamics
North Korean WaterPlum hackers infected 30,000 devices worldwide. A joint law-enforcement advisory said the North Korean-linked WaterPlum hacking group compromised at least 30,000 devices globally between December 2025 and July 2026. The advisory said more than $10.7 million in stolen cryptocurrency was transferred to North Korea.
