Brothers

Sisters can make you happier, and now researchers say brothers can keep you young. Girls with brothers don't grow up as fast as their bro-less peers — and it's not just the protective older brother factor. While older brothers delay the onset of menstruation by nearly a year, having a younger brother will postpone your first sexual experience by more than a year, according to the new Australian study.

So why do brothers have such a powerful impact? The study explains that older male siblings may take up parental resources or cause psychological stress that delays the onset of puberty. And when older sisters have to help take care of their little brothers it delays their behavioral maturation, pushing back the age that they'll lose their virginity.

If you were a late bloomer, did you also happen to have a brother? Do you think he had anything to do with it?

Looks like New Moon should have kept an eye on its blind side! The surprise hit has been nipping at the Twilight sequel's heels since they were both released two weeks ago, but this is the first weekend that the football drama actually took the top spot at the box office. The Blind Side earned $20.4 million, while New Moon pulled in $15.7 million.

In its first weekend out, Jake Gyllenhaal and Tobey Maguire's sibling thriller Brothers nabbed the third spot with $9.7 million, while A Christmas Carol continues to bring in audiences with $7.5 million. Rounding out the top five is Robin Williams's comedy Old Dogs, with a $6.9 million haul.

Jason Reitman's Up in the Air also had an impressive showing, taking in $1.2 million. The film was only open in 15 theaters, proving that all the hype is already paying off for the George Clooney dramedy.

Awards season is just around the corner, but not every December movie can be a winner. This week we've got a couple of clunkers and one shining star. Watch as the Buzz editors give you our two cents on Brothers, Up in the Air, and Everybody's Fine, and let us know your own thoughts in comments!

A remake of a Danish film, Brothers seems like potential Oscar bait — talented actors in a timely story of post-traumatic stress disorder for American soldiers. It has the most honorable of intentions to show the emotional toll that these men and women endure, but Brothers gets overwhelmed by the task and tries too hard.

Tobey Maguire plays Capt. Sam Cahill, a respected Marine and pride of his parents. After a helicopter crash in Afghanistan, he's pronounced dead, leaving behind his wife Grace (Natalie Portman) and two daughters. Stepping in to help the family is his younger brother Tommy (Jake Gyllenhaal), an ex-con with enough charm to make up for what he lacks in responsibility. As he spends time at the house with Grace, they turn to each other in their grief, blurring the line between in-law and love interest.

The thing is, Sam isn't dead. He was captured as a P.O.W., and when he comes home, he's a ticking time bomb. Paranoid over the burgeoning relationship between his brother and his wife and coping with memories of Afghanistan, Sam is skin and bones — a walking ghost of his former self.

Natalie Portman in brilliant blue stole the spotlight last night at a screening of Brothers in NYC. One of her two leading men, Tobey Maguire, joined her on the red carpet along with his wife Jennifer Meyer, though Jake Gyllenhaal missed the event. Amanda Peet was right by her husband David Benioff's side, supporting his latest screenwriting effort. Natalie was caught up in New Moon mania last week, but yesterday was all about her own upcoming project — check out the moving trailer before its release on December 4.
