Endometriosis is a condition in which tissue like the uterine lining grows outside the womb, often causing severe pelvic pain and sometimes infertility. In 1921 the American gynaecologist John Sampson studied patients with dark, fluid-filled cysts he called chocolate cysts and proposed that menstrual blood flowed backwards through the fallopian tubes into the pelvis, a theory now called retrograde menstruation. He named the condition endometriosis. Joe Vincent Meigs later argued that it appeared mostly in affluent, ambitious women who put off childbearing, and that pregnancy protected against it. The idea gave the condition the nickname the career-woman's disease and tied women's pain to their reproductive choices, a framing that persisted into later decades.

Indonesian Vice President Gibran Rakabuming Raka handed his resignation to parliament after questions were raised about his eligibility for office and his academic credentials. Gibran is the son of former president Joko Widodo, and his resignation came as Widodo publicly backed the president, Prabowo Subianto. Gibran had been elected vice president in 2024 as Prabowo's running mate. His candidacy was made possible by a 2023 Constitutional Court ruling on the minimum age for candidates, which was itself controversial. Parliament will now consider the resignation.

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.
