The royal newlyweds are here! Prince William and wife Kate, who took off from London on a private jet Thursday morning for their two-week tour of North America, reached Canada around 2 p.m. Thursday afternoon. After disembarking from their plane at Ottawa's Macdonald-Cartier International Airport, the couple were greeted by dignitaries and cheered by thousands of fans, People reports. (The former Ms. Middleton had thoughtfully changed en route into a dress made by Montreal-born designer Erdem Moralioglu in honor of the host country – having worn a blazer designed by another Canadian, Toronto-based Smythe Les Vestes, when she boarded the plane.) After making several stops in Canada in the coming days, they will then dip into the United States to visit California.

Despite a Food and Drug Administration panel's recent conclusion that the drug Avastin is not effective for the treatment of breast cancer, Medicare and Medicaid will continue to cover the cost of the medicine for patients whose doctors prescribe it. Centers for Medicare and Medicaid spokesman Don McLeod said Thursday that the FDA's final recommendation about Avastin's use will not affect its coverage as CMS frequently covers drugs for off-label uses, Reuters reports. "The drug will still be on the market, doctors will still be prescribing it and we will continue to pay for it," McLeod said.

"I want to offer a heartfelt and profound apology to the president, to my MSNBC colleagues and to the viewers. My remark was unacceptable, and I deeply regret it."

One for the "Life imitates art" file: Justin Timberlake, who played Napster co-founder Sean Parker in "The Social Network," a film about the launch of Facebook, has teamed up with a company called Specific Media to buy the social media site MySpace from News Corp. The deal, which closed Wednesday, will see Timberlake installed in an office at MySpace headquarters, in Beverly Hills, with a staff on hand to develop his ideas for the site "around the clock," Fox News reports. "There's a need for a place where fans can go to interact with their favorite entertainers, listen to music, watch videos, share and discover cool stuff and just connect," Timberlake said of his vision for the site. "MySpace has the potential to be that place."

Jared Lee Loughner, the suspect in the Tucson shooting rampage in which six people were killed and 13 others injured, including Rep. Gabrielle Giffords, can be forced to continue to take anti-psychotic drugs, U.S. District Judge Larry Burns ruled Wednesday. The judge said he wasn't inclined to question the prison doctors' assessment that Loughner, who has been diagnosed with schizophrenia and has violently lashed out repeatedly while in prison, is a danger. "I have no reason to disagree with the doctors here," Burns said, according to the Associated Press. "They labor in this vineyard every day."

Five women were arrested Tuesday by police in Saudi Arabia for getting behind the wheel to protest the country's ban on women driving. The arrests took place in Jidda, the country's second-largest city, The New York Times reports. Four of the women, ages 21 and 22, were taken into custody by police as they were riding together in one car; they were released after signing statements saying they would not drive again. The fifth woman was arrested while driving, unveiled, with her brother in the car; both were taken into custody. "If Saudi police think arresting women drivers is going to stop what has already become the largest women's rights movement in Saudi history, they are sorely mistaken," Saudi Women for Driving, the activist coalition behind the women's driving-rights movement, said in a statement. "On the contrary, these arrests will encourage more women to get behind the wheel in direct defiance of this ridiculous abuse of our most basic human rights."

No babies in first class: totally understandable or a total outrage? The debate is apparently raging on Twitter after Malaysia Airlines CEO Tengku Azmil announced that the airline's existing ban on babies in the first class sections of its Boeing 747-400 planes would be extended to include its Airbus A380 super jumbo jet fleet as well. "hv many complaints from 1st class pax dat dey spend money on 1st class & can't sleep due to crying infants," Azmil tweeted, by way of explanation. He later added, ""It is a tough call.There will be unhappy p#!@%*#engers either way."

"Diana would have been 50 this month. What would she have been like?" Newsweek editor Tina Brown wonders in the magazine's latest issue, which features on its cover a creative and controversial speculative rendering of what Princess Diana might have looked like, had she not been killed in a car crash in August 1997. Brown suspects that Diana would have still been "great-looking" with a Botoxed chin and gym-buff arms and a casual-glam look "a la Michelle Obama." She might have remarried – at least twice – moving "men of power" after choosing "boys of play," possibly moved to New York; hung out at Davos; become friends with her ex, Prince Charles, and forgiven his new wife, Camilla; and would struggled to share the spotlight with her new daughter-in-law, Kate Middleton but have "ostentatiously made Carole Middleton, Kate's dynamic mother, her new BFF." O ... K.

In a ruling that is sure to fan controversy, a Food and Drug Administration advisory committee voted 6-0 Wednesday that two key studies on which it made its accelerated approval of the drug Avastin for breast cancer use conditional showed that it is not effective in treating the disease, the Wall Street Journal reports. The panel also unanimously agreed that the drug had not been shown to have clinical benefits for breast cancer patients. The votes were a setback for the company that makes Avastin, Genentech, and also for patients who insist the drug has helped them in their struggles with breast cancer. (Previous studies indicated that the drug delayed tumor growth by about five-and-a-half months and improved the quality of life for the patients who used it.) Still unresolved is whether the panel will vote to retract its approval of the drug for breast cancer patients while further research is undertaken.
