Today's edition of quick hits:
* Texas: "The Arlington, Texas, police recruit who fatally shot an unarmed college football player during a break-in at a car dealership early Friday has been fired, the police chief said Tuesday. Christian Taylor, 19, was fatally shot by Arlington Police Officer Brad Miller, 49, after police were called to a break-in report at the Classic Buick GMC dealership at around 1:06 a.m."
* Missouri: "Amid concerns of renewed unrest on the streets of Ferguson, Mo., police said Wednesday that no one was arrested during Tuesday night's protests. Still, St. Louis County Executive Steve Stenger announced Wednesday afternoon that he was extending the state of emergency he had declared two days earlier."
* China: "With the Chinese renminbi now taking its biggest plunge in decades, the worry is that the country's already slowing economy is even worse off and the government is panicking."
* A rough prognosis: "Former President Jimmy Carter said Wednesday that his recent liver surgery has uncovered cancer in other parts of his body." In a statement, the 90-year-old Georgian said, "Recent liver surgery revealed that I have cancer that now is in other parts of my body. I will be re-arranging my schedule as necessary so I can undergo treatment by physicians at Emory Healthcare. A more complete public statement will be made when facts are known, possibly next week."
* A presidential letter to the editor: "In a heartfelt op-ed published on Wednesday, President Barack Obama urged Americans to fight for the equality that has slowly eroded since the Voting Rights Act was written into law 50 years ago. 'Congress must restore the Voting Rights Act. Our state leaders and legislature must make it easier -- not harder -- for more Americans to have their voices heard,' the president wrote in a letter to the editor for The New York Times Magazine."
* Imagine that: "Just 14 percent of Americans approve of the way Congress is doing its job, according to a new Gallup survey released Wednesday, and they do not seem all that enamored with Republican leaders in the House and Senate, either."
* If you haven't seen the images, they really are terrifying: "A powerful explosion rocked the Chinese port city of Tianjin on Wednesday, and police said at least seven people were killed. Chinese media reported that at least 300 people were injured."
