XPRIZE Wildfire was an $11 million, four-year competition launched in 2023 to find technology that detects and suppresses wildfires faster. It had two tracks. In the satellite track, teams had to spot fires across a large landscape in Australia within 10 minutes. In the autonomous track, they had to detect, navigate to and put out a fire in rural Alaska within 10 minutes of ignition, with no human help. The final tests were held earlier this year. No team won the grand prize in either track. The organisers say the technology has still improved enough that the focus now moves to working with the teams to turn it into scalable tools for real-world use.

Israeli reports also say the cabinet directed the military to prepare for a possible new attack on Iran.

Angkor, near Siem Reap in northern Cambodia, was the capital of the Khmer Empire, which ruled much of mainland Southeast Asia between roughly the 9th and 15th centuries. At its height the city spread across about 3,000 square kilometres, making it the largest pre-industrial city on Earth by area. Its growth depended on water: huge reservoirs called barays, along with canals and embankments, stored monsoon rain and carried it to rice fields. That system let farmers harvest more than once a year and fed a very large population through the dry season. The temple complex of Angkor Wat, built in the early 12th century, is the best-known monument and still stands at the heart of the park.
