Here’s what I’m reading up on this morning: 

• Russian separatists have trapped Ukrainian soldiers, as Poland declares what’s happening in Ukraine a war. 

• The U.N. says that three million Syrians–or about one of out every eight–have been displaced since 2011. 

• Speaking of Syria, Obama warns that using force isn’t always the best option. 

• West African students arriving on U.S. campuses this fall may be subjected to increased health checks.

• Google is testing its own drones to deliver goods.  

• Consumer spending declines for the first time in six months, down 0.1% in July. 

• Senegal confirms its first Ebola case. 

• Contagious yawns? Wolves do it, too. I keep yawning just thinking about it.
