Today's edition of quick hits:
* Getting the world's attention: "A series of extremely low passes by two Russian jets over a U.S. destroyer this week was a dangerous example of brinkmanship by Moscow in what has become an increasingly worrying trend, according to Western analysts."
* Texas: "A Texas deputy who was shot four times after a late night traffic stop on Thursday is expected to survive, authorities said. Deputy Alden Clopton, an 11-year veteran and field training officer with the Harris County Constable Precinct 7, was the victim of an 'ambush,' Lt. Holland Jones told reporters."
* ISIS: "President Barack Obama assured the American people on Wednesday that the United States has 'momentum' in the war against the Islamic State. 'We have momentum, and we intend to keep that momentum,' Obama said, delivering a statement at the CIA headquarters following a meeting with his National Security Council."
* In related news: "After several months of almost daily air strikes on the emerging Islamic State faction in Afghanistan, U.S. commanders in Kabul are scaling back their threat assessment for the Iraq-and-Syria-based extremist group that was gaining a foothold last year in one key Afghan province."
* Be alarmed: "Emerging from a winter that has had staggeringly warm Arctic temperatures, scientists monitoring the vast Greenland ice sheet announced Tuesday that it is experiencing a record-breaking level of melt for so early in the season."
* Coal's future appears bleak: "In the starkest sign yet of declining fortunes in the coal industry, St. Louis-based Peabody Energy, the largest and most storied U.S. coal company, announced early Wednesday that it was filing for Chapter 11 bankruptcy."
* Canada "unveiled an assisted death bill Thursday designed to ease the end of life for terminally ill patients while slamming the door on 'suicide tourism' to ensure Americans and others won't flock there to die. People with psychiatric problems also would be excluded, and no advance consent would be allowed."
* Look for more on this on tonight's show: "When the District sends its $13 billion budget to Congress this year, it might as well affix a sticky note that reads 'Dare you.' For the first time since the Founding Fathers carved out the nation's capital from swampland, the District will not ask the federal government for permission to spend its money. Instead, it will use local tax dollars as it sees fit, just as 50 states do."
