After six days of protests that packed the state capitol, Wisconsin's major teachers' union called on members to start returning to work Monday but keep fighting a proposed rollback of union protections for public
"To educators whose contracts do not recognize Presidents' Day, we call on them to return to duty by day - and find ways to be vocal and visible after their workday is done," Mary Bell, president of the nearly 100,000-member
Wisconsin Education Association Council, told members in a statement issued Sunday afternoon. "To those whose contracts recognize Presidents' Day as a holiday, we call on them to return to Madison."
But other unions said they plan to continue demonstrations into Tuesday, and not all members of Bell's union had decided to follow her lead. Members of Madison's WEAC local, the MTI Teachers Union, have voted to remain at the
capitol on Monday at least, its president, Mike Lipp, told CNN.

After weeks of anti-government protests in parts of North Africa and the Middle EastÂ - including revolts that prompted the ouster of longtime rulers in Tunisia and Egypt - unrest continues in several nations. Pressure on Libya's leader, in particular, seemed to be increasing fast on Sunday. SomeÂ roots of the unrest vary byÂ country, though many demonstrators are protesting against issues including unemployment and corruption. Here's a look at this and some of the other stories we plan to follow this week:
Libyan army told to restore security "at any price"
Unrest in Libya appears to be entering a critical phase this week, with the son of longtime Libyan leader Moammar Gadhafi promising widespread reforms - including increased salaries and a relaxed criminal code - in a televised address early Monday. But he also warned that Libya's army has been told to restore security "at any price," and that the country faces civil war if protesters go on.
Multiple eyewitnesses said late Sunday that Benghazi, Libya's second-largest city, is now in the hands of protesters and their military allies, some after dropping allegiances to Gadhafi. CNN cannot independently confirm these reports, because the Libyan government maintains tight control on communications and has not responded to repeated requests from CNN for access to the country.
[Updated: 5:14 a.m. Monday, Libya; 10:14 p.m. Sunday ET]: Eyewitnesses tell CNN by phone about tear gas and gunfire targeting anti-government demonstrators in Tripoli.Â After days ofÂ unrest, at least 219 people are dead, according to medical sources.
[Updated: 1:38 a.m. Monday, Libya; 6:38 p.m. Sunday ET]: Libya's army has been told to restore security "at any price" and will remain loyal to longtime leader Moammar Gadhafi, Gadhafi's son told Libyans in a televised address early Monday.

[Updated: 1:19 a.m. Monday, Libya; 6:19 p.m. Sunday ET]: The son of Moammar Gadhafi warned early Monday that the country faced "civil war" and a breakup of the nation if protesters go on.
[Updated: 1:09 a.m. Monday, Libya; 6:09 p.m. Sunday ET]: The son of Moammar Gadhafi said early Monday that a "great sedition"Â was under way in Benghazi, the country's second-largest city, but said the death toll was smaller than what is being reported by international news outlets.
[Updated: 12:08 a.m. Monday, Libya; 5:09 p.m. Sunday ET]: Multiple eyewitnesses have reported that BenghaziÂ is now in the hands of protesters and their military allies, some after dropping allegiances to longtime leader Moammar Gadhafi. VIDEO: Protester describes offensive

You've probably heard about the $10 billion particle-smashing machine underneath the border between France and Switzerland. To refresh, it's called the Large Hadron Collider, and its mission is to collide matter at unprecedented speeds and energies to figure out what our universe is made of and how it came to be.
In Washington on Sunday, I sat down with Yves Schutz of the European Organization for Nuclear Research (CERN). Schutz is a scientist with ALICE, an experiment designed to examine what the universe was like immediately after it was formed in the Big Bang. He had spoken about the experiment at the American Association for the Advancement of Science annual meeting.
Fifty-three people were killed in a 72-hour span in Ciudad Juarez, Mexico, making it one of the deadliest three-day periods in recent memory, state attorney general's office spokesman Arturo Sandoval told CNN Sunday.

"This is the worst violence we've seen this year," he said, referring to the three days from Thursday through Saturday.FULL STORY
Researchers at the University of Alaska-Fairbanks have figured out how bears hibernate, according to a recently published study.
It is the first study to examine the physiology of black bears during an experiment that lasted an entire hibernation season in a near-natural habitat. The results, published in Science, were released at the annual meeting of the American Association for the Advancement of Science.
The study's findings could reportedly help improve understanding of the metabolic rate of bed-bound patients or accident victims.
A day after thousands of joyous Bahrainis retook a major square in the heart of the island nation's capital, seven opposition groups were meeting in Bahrain to consider their next steps after an appeal from Crown Prince Salman bin Hamad al Khalifa for a national dialogue.
As the parties tried to coordinate a common position about a thousand protesters remained at the Pearl Roundabout, which has become this island nation's equivalent of Egypt's Tahrir Square. More Bahrainis came to the scene, many of them families. Groups of lawyers and teachers gathered to add their voice to the demand for political change and constitutional reform.
Opposition groups are considering a list of demands, which include an independent investigation into the deaths of protesters. Read the full story from CNN's Tim Lister and Rima Maktabi.

An Iraqi judge on Sunday adjourned proceedings for a week in the case of a British contractor accused of killing two colleagues in Baghdad.
Daniel Fitzsimons, 30, has pleaded not guilty to two charges of murder in the 2009 shooting deaths of Paul McGuigan, a British national, and Darren Hoare, an Australian. He is also accused of the attempted murder of a guard.
Fitzsimons has admitted to the three-judge panel that he shot the two men, but argued that it was in self-defense. He also complained that the court would not let him talk about his post-traumatic stress disorder.
The court had already issued one delay in the case in order to ask a health committee for a report on PTSD. However, when the court reconvened on Sunday, the court still had not received an answer from the committee, so a second delay was issued.FULL STORY
