Question: The uniformed members of the Bellefontaine Neighbors Police Department were injured in an encounter with a gunman around 7:15 a.m. local time  but expected to survive  according to Sgt.  Shawn McGuire of the St. Louis County Police Department.
  McGuire  said the incident began when the department received a call Wednesday night about shots fired in the suburb. Police were unable to locate the person related to the report  but they remained in the area overnight near a residence where they thought the shots potentially came from.
In the morning  police received a call from a neighbor who saw someone leave the house. Two officers located the individual  a 37-year-old man  walking down the street and tried to have a dialogue with him  according to  McGuire .
The officers ultimately attempted to take the man into custody and a scuffle ensued. At some point  the man took out a firearm and shot the officers   McGuire  said.
Ballistic vests worn by the officers blocked the rounds of gunfire but they still suffered some injuries. Both were hospitalized for treatment and evaluation  according to  McGuire .
The firearm used to shoot the officers has not yet been recovered   McGuire  said. The St. Louis County Police Department was on scene assisting with the barricaded suspect.

Answer: Standoff ensues after 2 police officers shot near St. Louis


Question: The idea: Since Attorney General Jeff Sessions recused himself from the Russia probe in March  he is not supervising special counsel Robert Mueller or his team. That means the buck stops with  the deputy attorney general  Rod Rosenstein .  Rosenstein  told the House Judiciary Committee Dec. 13  he  has seen no reason that would be "good cause" to remove the special counsel and that  he  has confidence in the investigation.
One way for the White House to shake up the probe is to find a way to replace the attorney general  who is recused  with someone who is not. That person could then exercise more control over the Russia investigation  including nixing some spending by the special counsel  refusing to sign off on interviews of key witnesses or requests for grand jury indictments â or even firing  Mueller .
The problem: Sessions is having the time of  his  life at the Justice Department  and doesn't want to go anywhere. Earlier this year   he  rebuffed efforts to mount a write-in campaign for  his  old Senate seat in Alabama  and another effort to get  him  to move over to the Department of Homeland Security.
The problem:  the current Deputy Attorney General  Rod Rosenstein   appeared to draw  his  own line in the sand in recent House testimony  telling lawmakers that special counsel Robert Mueller was among the best civil servants and law enforcement officials in modern history. The new FBI Director  Christopher Wray  is also a fan of Mueller's. And in a standoff during the George W. Bush presidency over surveillance measures the Justice Department balked at approving  Wray also volunteered to resign in protest along with a series of other senior DOJ officials. In other words  the specter of another mass resignation at the top of the Justice Department and the FBI would loom large.

Question: Three Americans â Jeffrey C. Hall   Michael Rosbash and Michael W. Young â  have won the 2017 Nobel Prize in physiology or medicine for  their  work on molecular mechanisms that control circadian systems.
Hall was born in New York  Rosbash in Kansas City  and they both worked at Brandeis University.  Michael Young  was born in Miami and worked at Rockefeller University.

The trio's early work took place in 1984 when Hall and Rosbash worked together at Brandeis and  Young  at Rockefeller University to isolate the "period" gene  which controls the circadian rhythm of fruit flies. Hall and Rosbash then showed that the level of the protein encoded by this gene changes in a 24-hour cycle  going up during the day and down at night. They theorized that this protein blocked the activity of the period gene.
