A genetic survey of howler monkeys (genus Alouatta) has found two Amazonian species that science hadn't formally recognised: the Pantepui red howler (Alouatta iroi) in the north-west Amazon and the Mato Grosso red howler (Alouatta matogrossensis) in southern Brazil. The researchers analysed more than 2 terabytes of genomic data, plus physical features and museum specimens. Monkeys on opposite banks of the Branco River formed separate genetic lineages, and A. iroi also has yellower fur. A population in the Caribbean may also be a distinct species, and some other populations may need reclassifying.

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.
