Capital is humming across the Japanese venture complex this morning — drone shows, smart purikura, even space-trading are all pulling new rounds — but the two MIT Tech Review pieces that close this batch are doing the heavier lifting of the day. One asks whether the summer heat is quietly degrading cognition, the other shows that calling an AI agent an "employee" measurably makes humans worse at catching its mistakes. Money is moving; brains, both human and silicon, are under pressure.

• 熱波が奪うのは体力だけではない、暑さが脳に及ぼす影響は？ — Many readers have felt the brain fog and lost concentration that comes with extreme heat. The exact mechanisms are still unclear, but multiple studies suggest people with mental illness and children are especially vulnerable to heatwaves. (Source: MITテクノロジーレビュー) (In Japanese Language)
• AIエージェントの「従業員化」、作業ミスの見逃しを招く — More companies are treating AI agents less like tools and more like employees — but that framing may actually reduce the quality of human work.
