The latest on the crisis in Ukraine, plus a look at the key 2014 Senate races.
(CNN) – Cancer cases are expected to surge 57% worldwide in the next 20 years, an imminent "human disaster" that will require a renewed focus on prevention to combat, according to the World Health Organization.
(CNN) - The President said he does not think marijuana is more dangerous than alcohol, according to a recent interview with The New Yorker.
But when CNN asked him if he was willing to downgrade pot from a "Schedule One" narcotic, a category reserved for substances like heroin and LSD, Obama put the responsibility on Congress to make the move.
But according the Drug Enforcement Administration's own website, the President's Attorney General has the authority to "remove any drug or other substance from the schedules," if he thinks it's been mislabeled.

(CNN) - Director of National Intelligence James Clapper testified last week in front of the Senate Intelligence committee that the al Qaeda tied group in Syria, al-Nusra Front, has "aspirations" for attacks in the U.S.

(CNN) - "Jeopardy!" champion Arthur Chu has so far won $102,800 in a four-game winning streak that is dividing fans of the popular game show.
The 30-year-old insurance analyst and aspiring actor has been both criticized and praised for turning the game on its head.
Instead of completing categories from top to bottom, Chu jumps around the board to find the Daily Doubles, sometimes bets odd amounts on them, and places final wagers to tie instead of win the game.
But he's not the first game-theory devotee to take "Jeopardy!" by storm.
"Everything I have done has been done by past champions," Chu told CNN's "The Lead with Jake Tapper."
