A truffle is not a root or a nut but the fruiting body of a fungus that lives underground, mostly in the genus Tuber. The visible part is only the reproductive structure, while most of the organism is a web of threads spread through the soil. Truffles are ectomycorrhizal, meaning they form a partnership with tree roots: the fungus supplies water and minerals to the tree and receives sugars in return. Because they grow hidden, their spores are spread when animals dig up and eat them and pass the spores on in their droppings. Some species are prized in Italian and French haute cuisine, and many are now cultivated.

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.
