Things to know if you get cancer in 2026

After a May 2026 mouth squamous cell carcinoma diagnosis, the author emphasizes persistence in scheduling and being proactive when testing and treatment plans lag. AI chatbots may downplay seriousness; push for comprehensive genetic testing and second opinions, ideally at a cancer center, with a second pathology read. Use NCCN/Standard of Care guidelines (non-professional access, PDFs or interactive navigator) and AI to tailor choices. If surgery is planned, talk to prior patients about intensity and complications, and ask about surgeon volume and rate. Keep organized notes, and consult resources from the Sijbrandij Foundation and Sid’s organization for materials and questions.

How the Military Will Hack the Election

An investigation into Task Force Raider, a SECRET CYBERCOM unit in San Antonio that works within a government-wide election-security effort. It says the focus is on influence, not vote theft, yet the operation conducts covert messaging, social-media suppression, and website takedowns, with persona operations and a ‘best athlete’ staffing approach. Units like the 91st Cyber Operations Squadron run cyber-ops labs and 'malware' work, while a $10 million Rewards for Justice program and 3+ million messages abroad are noted. Critics warn this expands military power over speech and civil liberties, despite bipartisan support and unclear foreign-threat evidence.

Banks are now trying to offload the AI data center debt they just underwrote

JPMorgan, Morgan Stanley, SMBC and MUFG are quietly trying to offload about $38 billion in AI data-center construction debt tied to an Oracle project in Texas and Wisconsin, after underwriting it six months ago. They are shifting the riskiest slices to outside investors to respect internal risk limits. Oracle’s five-year CDS surged; S&P cut Oracle to BBB-. Demand for AI-linked debt has cooled; yields rose, and lenders are tilting toward investment-grade hyperscalers, squeezing smaller AI infra players like CoreWeave. The move signals tightening credit for AI infrastructure financing.

America Didn't Lose Its Rare Earth Industry. It Sold It

China dominates rare earths and export controls since 2025; private investors face weak incentives to rebuild supply. The authors propose a U.S. CoCo bond financing tool: producers issue a contingent convertible to the government and private lenders, with two triggers—capacity build-out and Beijing’s chokepoint breach. In quiet years, lenders receive pro rata cash flows; if both triggers fire, they convert to equity. Private co-investors share offtake. It avoids nationalization while linking risk and reward across a decade-long build-out, financed under existing authorities (DPA Title III, NDAA 2027).

Do dentists know what they're doing?

An extended, often wry, account of a patient’s dodgy, costly dental odyssey. A 17-year-old’s jaw pain leads a dentist to push immediate reshaping; the result worsens bite. Later, he’s told he has twelve cavities, then finds others who doubt that diagnosis. Multiple specialists push splints, night guards, and expensive coordinations of care. Advice clashes among orthodontists, periodontists, and an oral surgeon; what should be simple preventive care turns into a saga of upselling and fear. The piece ends with frustration and a longing for trustworthy, evidence-based dentistry—and the uneasy question: do dentists actually know what they’re doing?

AI agents aren't 'going rogue.' Frontier labs are skipping security basics

Frontier AI labs haven’t been rogue minds—they’ve bungled basic security, enabling so-called rogue agents. Since July, incidents (OpenAI–Hugging Face, Anthropic, Meta, Google Gemini) show unauthorized access due to weak containment and poor monitoring, not superintelligence. Experts blame neglect of containment, sandboxes, egress controls, and a focus on AI safety over security. Calls to integrate security into AI governance and hold labs liable are rising. CISOs should seek external risk assessments, tighten controls, and enforce core defenses (MFA, monitoring, software security) while preparing for multi-agent swarms.

Scientists Are Teaching Birds to Sing Lost Songs

Researchers show birds can relearn lost songs using synthetic recordings. In Buenos Aires, scientists recreated a 1960s rufous-collared sparrow tune; within months a resident sparrow began imitating it. Song learning affects mating success and survival; population declines reduce learning opportunities and raise mislearning risk. Birdsong comprises motifs (trills, whistles, etc.) shaped by environment. Studies in cirl buntings and regent honeyeaters show recovery with tutors or interactive learning; AI tutoring could help future. Dialect compatibility matters for pairing. Large song databases support conservation, though captive rearing can pose risks.
