Willow bark was used against fever and pain for thousands of years, appearing on clay tablets from ancient Sumer and in Hippocrates's writing. In the 1760s, the English clergyman Edward Stone tested powdered willow bark for five years and reported it to the Royal Society as effective as Peruvian bark. In 1853, Charles Frédéric Gerhardt first made acetylsalicylic acid, and in 1897 Bayer chemists produced it in a pure, stable form. The name came from spiraea, the meadowsweet plant that yields salicylic acid. Aspirin was Bayer's brand name, but the company lost its trademark in the United States after letting other makers use the name.

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.
