An international team of researchers developed a self-powered capsule that tests and disinfects water without batteries, filters, or chemicals. Three seconds of shaking generates enough electricity to measure water quality via Bluetooth, then floating motion powers disinfection — eliminating 99.9999% of microorganisms across 120+ cycles.

Un equipo internacional de investigadores desarrolló una cápsula autopropulsada que analiza y desinfecta el agua sin baterías, filtros ni productos químicos. Tres segundos de agitación generan electricidad suficiente para medir la calidad del agua vía Bluetooth; el movimiento flotante activa la desinfección, eliminando el 99,9999% de microorganismos en más de 120 ciclos.

Xiangqi Chen left China, and opened the OUT Museum in San Francisco's Chinatown — the first of its kind for Chinese and diaspora queer artists. Launched in May 2026 with over 2,000 early supporters, the bilingual museum has already brought together generations and families across lines long considered uncrossable.

A Cornell University political scientist has statistically debunked two decades of influential U.S. research claiming politicians ignore ordinary voters. The flawed studies used selective data and triggered Simpson's paradox. The real gap in political influence, the new analysis finds, lies between the general public and the ultra-wealthy — not between middle- and upper-income groups.
