Tuesday: Dalhousie investigation, Vatican nuns, speed dreidel, and more...

Students and faculty at Dalhousie University are stunned when a Facebook group -- made up of male students sharing misogynistic and disturbing comments about women -- is unmasked...A new Vatican report into U.S. nuns strikes a more conciliatory tone towards their social-justice activities, after a previous report questioned the nuns' actions...and for a game that spins tops, it can be agonizingly slow. So one man has come up with "speed dreidels," to help Hanukkah parties end on time.

Part One

Dalhousie investigation
For a Facebook group calling itself a gentleman's club, its posts were decidedly lacking in good character. Halifax's Dalhousie University is stunned when some male dentistry students are revealed to have shared sexually explicit messages -- some about their female classmates.

Peshawar: Taliban attack
Scores of students are killed when the Taliban attacks a school in Peshawar, near Pakistan's border with Afghanistan.

Excessive punctuation
Amazon reinstates an author's book on its Kindle site, after initially rejecting it because the text contained too many hyphens.

Part Two

Oil: Canada housing market
Just like the party's over for oil prices, a business columnist argues the same could be true for Canada's housing market.

Speed dreidel
The Hanukkah game of dreidels is long, slow and boring -- and a writer for Slate magazine says he has the science to back up his claim. So now he's come up with a shorter, less slow and boring version of the traditional game, called "Speed Dreidels."

Part Three

Vatican nuns
The Vatican has been critical of the social activism of American nuns -- but a new report is suprisingly conciliatory, signalling a new order of business from Rome.
