A mix of resilience stories this morning. Heat pumps in the US keep selling even after their tax credit expired; researchers push back on the perimenopause-everything trend online; and a major Japanese food company (Nichirei) joins the ransomware casualty list, while CISA + JPCERT/CC quietly lay down new vulnerability-disclosure rules for everyone else. Add in an $88 billion Asia-Pacific scam haul from the UN, a fresh Japan-UK diplomatic handshake under new PM Burnham, and two JPX market-structure notices, and you’ve got a round that’s equal parts security hardening, financial plumbing, and geopolitics. The throughline feels like infrastructure under stress — corporate, financial, and human — and how each one responds.

• 税額控除終了後も売れ行き好調、米国ヒートポンプ市場の底堅さ (MITテクノロジーレビュー) — Even though the US tax credit of up to $2,000 expired at the end of 2025, heat pump sales haven’t dropped in 2026 — a striking contrast with EVs, which saw a sharp sales slide once their credit ended. The numbers are unusually strong for a heating technology in the middle of summer. (In Japanese Language)

• 脆弱性報告を受け付けない企業は危うい？　CISAら5機関が共同指針 (＠IT Security&Trustフォーラム 最新記事一覧) — "I found a bug but there’s no one to tell, and I can’t tell if it got fixed." CISA, NSA, JPCERT/CC, and two other agencies have published a joint guideline for enterprises laying out new vulnerability-management practice built around cooperation with good-faith researchers.
