Moviegoers: How many female protagonists did you see in 2014? If you're struggling to come up with anything besides Hunger Games, Gone Girl and Wild, there's a good reason: New research from the Center for the Women in Television and Film at San Diego State University reveals women comprised just 12 percent of the protagonists of 2014's top-grossing films.

The news isn't much better for supporting roles. Women comprised just 29 percent of major characters, and just 30 percent of all speaking characters.

Study author Dr. Martha Lauzen thinks the key to diversifying Hollywood is diversifying the people who make movies. "People tend to create what they know, and having lived their lives as females, women tend to be drawn to female characters," she said. "We need to have greater diversity behind the scenes if this is going to change." Jack McCormick

In December, Chef Benoit Violier's restaurant near Lausanne, Switzerland, was named the world's best by France's La Liste, which ranks the world's 1,000 best eateries. Swiss police say Violier, 44, was found dead Sunday afternoon in his home in Crissier, the town that also houses Violier's Restaurant de l'Hotel de Ville, rated three stars by Michelin. "It would seem that he has ended his life with a firearm," the police said in a statement. Violier had worked in the restaurant since 1996, and took it over along with his wife, Brigitte, in 2012.

Violier was born to a winemaking family in western France, and moved to Paris in 1991 to study with top chefs. He earned a reputation for inventiveness and perfectionism, especially in preparing wild game, and was named 2013 chef of the year by the influential Gault and Millau guide. Police aren't releasing any more details about his death, but French media speculates that Violier was upset over a slight demotion in the Gault and Millau guide and fear that he was about to lose a Michelin star, The New York Times reports. His apparent suicide also comes just a few months after the sudden death of his mentor Philippe Rochat, the previous head chef at the Restaurant de l'Hotel de Ville. Peter Weber

This evening, Iowa voters gather in churches, schools, and community centers to debate the relative merits of each 2016 presidential candidate and try to persuade their fellow caucus-goers to support one candidate or another. The caucuses are very different than primaries, and the time commitment and peculiar rules mean that typically only 20 percent of Iowa voters caucus, reports James Rosen at Fox News. Adding to the confusion, Democrats and Republicans caucus differently, with Republicans writing their preference down on sheets of paper and Democrats gathering in groups in different areas of the caucus room. Thanks to a new smartphone app from Microsoft, we will probably know the results Monday night, but if you're curious about how Iowans get to a winner, watch Rosen's report below. Peter Weber

The two leading Democratic presidential candidates are crushing the fractured GOP field in the money race, according to fourth-quarter filings with the Federal Election Commission released Sunday. Leading all candidates in the last quarter was Hillary Clinton, who brought in $37.4 million, plus another $56.3 million raised in 2015 by her super PAC, Priorities USA Action (including $6 million from George Soros). The Sen. Bernie Sanders (I-Vt.) campaign wasn't far behind, raising $33.6 million in the last quarter, plus, the campaign said Sunday, another $20 million in January, mostly from small donations. The nurses union super PAC backing Sanders raised $2.2 million in the second half of 2015.

On the Republican side, retired pediatric neurosurgeon Dr. Ben Carson had the best quarter, hauling in $22.6 million — but 85 percent of that was raised before Nov. 13, when his poll numbers started to slide as the Paris terrorist attack shifted the GOP's focus to terrorism and foreign policy. Sen. Ted Cruz came in second in the GOP fourth-quarter money race, raising $20.5 million. The frontrunner in the GOP polls, Donald Trump, raised $13.6 million in the last quarter, though about $10 million of that was a loan from Trump to his campaign. Here's a look at how much the major candidates raised in the final three months of 2015 and, in parentheses, the amount of cash they had on hand as of Dec. 31.

Hillary Clinton: $37.4 million ($38 million)
Bernie Sanders: $33.6 million ($28 million)
Ben Carson: $22.6 million ($6.6 million)
Ted Cruz: $20.5 million ($18.7 million)
Marco Rubio: $14.2 million ($10.4 million)
Donald Trump: $13.6 million ($7 million)
Jeb Bush: $7.1 milion ($7.6 million)
John Kasich: $3.2 million ($2.5 million)
Chris Christie: $3 million ($1.1 million)
Carly Fiorina: $2.9 million ($4.5 million)
Rand Paul: $2.1 million ($1.3 million)
Martin O'Malley: $1.5 million ($0.2 million)

None of the other candidates raised more than $1 million last quarter. Mike Huckabee scared up $700,000, and Rick Santorum raised less than $250,000, including a $24,000 loan he gave his campaign on Dec. 29. Santorum reported $43,000 cash on hand, but debts totaling $167,000. Peter Weber

The Department of Justice will administer a "comprehensive review" of the San Francisco Police Department, following the Dec. 2 shooting of Mario Woods, a 26-year-old black man.

The investigation will be officially announced Monday, the San Francisco Chronicle reports, and will be led by the Office of Community Oriented Policing Services, an agency that works with police forces to forge stronger bonds with communities.

In the case of Woods, Police Chief Greg Suhr said he was allegedly carrying a knife that he used in an earlier stabbing, and five officers shot him after they couldn't disarm him with pepper spray and beanbags. The shooting was captured by a witness on camera, and critics say it shows Woods with his arms at his sides, struggling to walk, the Chronicle reports. John Burris, the attorney representing Woods' family, says he is in favor of the review. "This can be the first step in healing the division between the minority communities and the police department," he said. "Of course, the investigation should be without limitations and should allow for a wide open investigation into the circumstances surrounding the shooting and the policies, procedures, and training, and let the chips fall where they may."

It has been an incredible week for Cedrick Argueta of Los Angeles — first, he found out he earned a perfect score on the AP Calculus test, then he was personally invited by President Obama to the next White House Science Fair.

The 17-year-old Lincoln High School senior correctly answered more than 60 multiple choice and free-response questions on the fundamental theories of calculus, and was one of just 12 students in the world — out of the 302,532 who took the test last May — to do so. Argueta didn't stop there — the Los Angeles Unified School District announced he also received perfect scores on the English and math sections of the ACT college-entrance exam. "All the credit can't come to me," he told NBC Los Angeles. "I have to give credit to all my classmates and my teachers."

Argueta — who also volunteers at the convalescent hospital where his parents work — plans to one day work as an engineer at the NASA Jet Propulsion Lab, and is hoping to get accepted to Caltech. Catherine Garcia

Time Warner Inc. is in serious talks to buy a 25 percent stake in video-streaming service Hulu, and it has an agenda: to stanch the flow of people ditching pay-TV for online streaming, The Wall Street Journal reports, citing "people familiar with the discussions." The discussions are centered around Hulu's competitive advantage over rivals Netflix and Amazon: It posts episodes from the current seasons of TV shows, sometimes the day after they air on TV. Time Warner believes that the current seasons on Hulu contribute to people "cutting the cord," or dropping the pay-TV subscriptions that account for the bulk of Time Warner's profits.

Time Warner wants current seasons of its shows — it owns networks TBS and TNT, among others — off Hulu but won't make that a condition for buying a quarter of the company, The Journal says. But its long-term goal is to make online streaming tied to pay-TV subscriptions, and Hulu just might play along. Already, Hulu puts some TV shows behind a paywall for pay-TV subscribers, a plan that Time Warner has endorsed in the past. That would be bad news for cord-cutters, but probably not fatal for Hulu. Thanks to its acquisition of Seinfeld and other older shows, plus its original series, only about a quarter of its streams today are reportedly tied to current-season deals.

Hulu's current owners include Walt Disney Co., Comcast, and 21st Century Fox. It has 10 million U.S. subscribers, versus Netflix's 45 million. You can read more about Time Warner's intentions at The Wall Street Journal. Peter Weber

At least 86 people were killed Saturday night in northeastern Nigeria during an attack by Boko Haram extremists.

Witnesses said the militants firebombed huts in the village of Dalori and started shooting at people as they tried to escape, Al Jazeera reports. Children were burned alive, and survivors said they heard screaming as huts and houses were razed. Officials say 62 people are being treated for burns in a nearby hospital, and troops were able to keep the extremists from entering a camp close to Dalori that houses 25,000 refugees. Catherine Garcia
