據高盛統計，Meta、微軟、Alphabet、亞馬遜和甲骨文的季度自由現金流，2026年二季度合計已降至接近零。最新財報印證了現金流壓力：Alphabet二季度自由現金流首次轉爲−58.6億美元，Meta僅剩7.84億美元；亞馬遜當季資本開支超過經營現金流約88億美元，而微軟仍實現196億美元自由現金流。 這並不等於五家公司主營業務開始“燒錢”，而是AI服務器、數據中心和電力基礎設施的投入增速暫時超過經營現金流增速。現金流收縮正推動科技巨頭減少回購，並更多依賴債券、股權和項目融資，AI投資週期由“利潤自籌”轉向“外部融資”。 分析師預測2029年單季自由現金流將升至約1200億美元，其前提是資本開支增速明顯放緩，同時雲計算與AI收入快速兌現。若算力需求繼續超過供給、設備價格上漲或AI變現不及預期，反彈時間可能後移。

Imperial College London said its candidate rhinovirus vaccine APL-10456 produced encouraging preliminary Phase I results. A single dose was well tolerated and elicited immune responses against the three major rhinovirus groups. The randomized, placebo-controlled Phase I enrolled 144 healthy volunteers; the first stage tested three single-dose levels in 18–54-year-olds, assessing safety, tolerability and immunogenicity. A second stage is evaluating a two-dose regimen in adults 55 and older, with additional data expected in Q4.
