But even as some 40 heads of state gathered in Jerusalem this week to commemorate the six million Jews who were killed, a recent Pew survey revealed that many American adults don't know basic facts about the ethnic cleansing of Europe's Jews during the Second World War.

A quarantine in China– Local authorities have locked down the city of Wuhan, the source of the outbreak of a new and potentially deadly respiratory virus that, as of Thursday morning, had infected more than 540 people in at least six countries.

Public transportation is shut, and local officials are urging everyone to stay put unless they have a special need to travel. Wuhan is a city of 11 million people, many of whom were about to travel for the Chinese New Year. We're watching to see whether these extraordinary measures help stem the outbreak, but also to see how the people affected respond to the clampdown.
