The day's signal
A 710-metre space rock spinning once every 1.88 minutes should not exist by the rules of rubble-pile physics. Its discovery by the Vera C. Rubin Observatory could force a major rethink of how asteroids are held together.
Trump sanctions the ICC's Japanese president. Japan declined to join a joint condemnation. The emergency reprint of her book reveals what's at stake for multilateral justice — and for Tokyo's uncomfortable position between allies.
South Korea's KOSPI lost a third of its value in two months as retail investors who borrowed billions to chase AI-semiconductor stocks were caught in a margin-call spiral. The fallout raises questions about market stability in economies where two firms dominate half the index.
The execution of Sunao Takami marks a new phase in Japan's capital punishment regime — one that combines domestic political signaling with mounting international isolation. What happens next for Japan's 100 death-row inmates.
Kakao is splitting its AI and messaging business from its financial services empire — a structural gamble that could define how platform giants price their bets in the age of artificial intelligence.
A man running an AI-generated fake female identity for Japan's Constitutional Democratic Party exposes a vulnerability all democracies now face. Disclosure laws can't keep up.

A Falcon 9 upper stage slammed into the Moon in August 2026, creating a fresh crater NASA has now imaged. The incident reveals how little oversight governs debris in cislunar space — and what that means for everyone racing to build there.
A massive object orbiting a brown dwarf 73 light-years away could be the first confirmed exomoon — and it forces astronomers to confront a simple problem: the word 'moon' no longer fits what they're finding.
