A Window into Early Twentieth-Century Arabic Manuscripts Transactions

A cooperation between the American University in Cairo (AUC) and five academic institutions, including the Institute for Advanced Study, has seen a rare archive documenting the al-Khanji family's cultural impact on early twentieth-century Cairo transferred to AUC. The unique collection, consisting of thousands of documents, reveals the family's significant role in the trade and publishing of manuscripts, offering unprecedented insights into the intellectual networks of the time.

Astrophysicists Use Echoes of Light to Illuminate Black Holes

Their novel method, which will make it easier for the mass and the spin of black holes to be measured, represents a major step forward, since it operates independently of many of the other ways in which scientists have probed these parameters in the past.
