Happy Friday!

From Julie: Time travelers are welcome at Stephen Hawking’s memorial service in June. 

Also from Julie: Scientists may have found a drug to combat the common cold! 

From Cassandra: Working class people are more empathic. Also more fatalistic. Well, you’ll have that.

From the people behind Retronaut: Freevious, high-quality public domain photographs!

From Twitter: The hockey playoffs have extended to a (friendly) Twitter war between the Winnipeg and Las Vegas public libraries. 

Have a safe and spiffy weekend, everyone. See you next week.
