[Q]: A nurse's release Tuesday from an Atlanta hospital leaves a single person in the United States now battling Ebola, though she and others -- including President Barack Obama -- stressed the fight against the deadly virus isn't over. "While this is a day for celebration and gratitude, I ask that we not lose focus on the thousands of families who continue to labor under the burden of this disease in West Africa," said 29-year-old Amber Vinson. About two weeks ago, Vinson became the second nurse from Texas Health Presbyterian Hospital Dallas to get the virus while caring for Thomas Eric Duncan, a Liberian man who began showing Ebola symptoms after arriving in Texas and died of it there.

[Q]: (CNN) When three-year-old thoroughbred Patch takes to the starting gate at this year's Kentucky Derby Saturday, many people -- be it in the stands or watching on TV -- probably won't be aware that this is a very special horse. At the left-hand side of Patch's head is a dark hole -- about the size of a golf ball -- where his eye used to be. As a two-year-old, Patch developed an ulcer in his left eye that, despite the best possible medical care, didn't respond to treatment. Eventually, in June 2016, the colt had his eye removed after trainer Todd Pletcher decided nothing more could be done to save it.One-eyed Patch racing in Kentucky DerbyRace has purse of $2.4 million
