The government and rebels signed the ceasefire agreement on Thursday after talks in Ethiopia.
More than 500,000 people have been forced from their homes during the month-long conflict.
Correspondents say that effective monitoring of the truce will be vital, as tension between the two sides is very high.
The talks have now been adjourned and are due to continue on 7 February.
Pregnant Woman on Life Support Stirs Political Debate →
At 14 weeks pregnant in November, Marlise Muñoz, 33, suffered what doctors believe was a pulmonary embolism. She was nearly dead when her husband, paramedic Erick Muñoz, found her collapsed in their home. Although Erick Muñoz and Marlise Muñoz's family wanted to honor her desire not to be placed on life support, more than a month later, doctors are still keeping her alive at John Peter Smith Hospital in Fort Worth. The hospital can detect a fetal heartbeat, but the health and viability of the fetus are unknown.
“The law says you cannot withhold or withdraw life-sustaining treatment from a pregnant patient — period,” said J.R. Labbe, a spokeswoman for the hospital. “We believe the course of action we’re doing is the correct one.”

Can Europe protect the Euromaidan? →
Events in Ukraine have taken a dramatic change for the worse. Five people were killed on Wednesday, some beaten to death, and further confrontation is likely this Sunday.

THE CULT OF OVERWORK →
...But, as David Solomon, the global co-head of investment banking at Goldman, told me, “Today, technology means that we’re all available 24/7. And, because everyone demands instant gratification and instant connectivity, there are no boundaries, no breaks.”
Cry me a river, you might say. But what happened on Wall Street is just an extreme version of what’s happened to so-called knowledge workers in general. Thirty years ago, the best-paid workers in the U.S. were much less likely to work long days than low-paid workers were. By 2006, the best paid were twice as likely to work long hours as the poorly paid, and the trend seems to be accelerating.
...The perplexing thing about the cult of overwork is that, as we’ve known for a while, long hours diminish both productivity and quality.
Someone Just Said Something About The Japan-China Conflict That Scared The Crap Out Of Everyone →
During the dinner, the hosts passed a microphone around the table and asked guests to speak briefly about something that they thought would interest the group.
One of the guests, an influential Chinese professional, talked about the simmering conflict between China and Japan over a group of tiny islands in the Pacific.
...
The Chinese professional at dinner last night did not seem so much worried about a military conflict as convinced that one was inevitable. And not because of any strategic value of the islands themselves (they're basically worthless), but because China and Japan increasingly hate each other.
Consumer Manipulation →
One of my worries about our modern market system is that the manipulators have gotten too good. We need better security -- either technical defenses or legal prohibitions -- against this manipulation.
