Daily Recap: Science — 27 September 2026

Nature and technology drive the day’s science news, from an unusually visible insect migration on Australia’s east coast to a decade-old storm that helps reshape thinking about how electricity grids can stay stable. Together, the stories show science at work both in sudden disruptions and in the long-term systems built to manage them.

A huge South Australian storm that knocked out power a decade ago helps set off a wider shift in electricity-grid technology. The event fuels a high-profile bet between two billionaires and becomes a public test of rival ideas about grid reliability, battery storage and how power systems can respond faster to major disruptions.

Thousands of bogong moths swarm homes in Sydney and along parts of the New South Wales south coast as winds disrupt their annual migration. Residents report properties covered in insects during a seasonal movement that normally carries the moths south, turning a regular natural event into a striking urban encounter.
