By 1940, the French banker and philanthropist Albert Kahn had gathered more than 72,000 autochrome photographs for his Archives de la Planete, a project to document the world as it changed. Autochromes were an early colour process invented by the Lumiere brothers, and they produce soft, glowing images on glass plates. Kahn funded teams of photographers who travelled across many countries to record daily life, landscapes and urban scenes. The result is a global visual archive from the early twentieth century, and its colours give the past a vivid, dreamlike quality.

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.
