It’s official: Ebola is still spreading. Senegal has confirmed its first case of the disease that’s ravaged West Africa killing more than 1,500. The news comes only a day after World Health Organization officials announced that they expect to see perhaps as many as 20,000 cases before the current outbreak is quelled, which is nearly seven times as many as we’ve seen so far. Meanwhile, back in the United States, universities and colleges have begun to screen students coming from that region of the world as a precaution to help prevent the disease from spreading back home.

Meanwhile, pro-Russia separatists now control a strategic coastal town where Russian tanks came barreling in just yesterday, and Ukraine is trying to join NATO in order to get protection help from the Western military alliance.
