naked mole-rat hyaluronan gene mice lifespan

A mole-rat gene raised mice's median lifespan

~4.4%

Naked mole-rats produce unusually large amounts of hyaluronan, a molecule implicated in their resistance to cancer. Mice given the gene responsible for this form of hyaluronan had improved health and a median lifespan about 4.4% longer.

Russia's conquest drove Circassians from their homeland

During the Russian Empire's nineteenth-century conquest of the northwestern Caucasus, enormous numbers of Circassians were killed, expelled or forced to flee. Many refugees died during journeys across the Black Sea and resettlement in Ottoman territory.
