At a basic level, kissing is a biohazard. What is love then, if not the willingness to expose yourself to a host of nasty diseases lurking in your partner's mouth?
But could kissing also be a tool with a purpose?
Psychology graduate student Rafael Wlodarski, from the University of Oxford, wanted to find out. Results from his experiments supported two of the existing hypotheses about why we kiss. First, we kiss to assess potential mates. Second, we kiss the mate we've found to maintain attachment.
Now we have an update this morning on Colorado's legalization of marijuana. This week we told you opponents of a proposed marijuana tax have been handing out free joints at rallies in Colorado. An ethics group is insisting the pot must disclosed as a campaign contribution. And now the mayor of Denver wants to act. Mayor Michael Hancock tells our friends at Colorado Public Radio he's proposing to outlaw handouts of free weed in city parks.
Back in 2009, you may recall, Somali pirates boarded the cargo ship Alabama. The tension between the pirates and the American captain, Richard Phillips, is the basis for a new film in theaters this weekend, and critic Kenneth Turan has our review.

KENNETH TURAN, BYLINE: The cargo ship Alabama is headed down the east coast of Africa when Captain Richard Phillips, played by Tom Hanks, sees something no captain in these waters wants to see.
Let's hear, next, about investors who try to diversify their portfolios but may have only enriched their advisers. Some brokers and firms have been encouraging customers to invest in managed futures. Those are basically investments in futures contracts, such as gold, or global currencies or pork bellies. They are sold as a way to minimize risk.
David Evans of Bloomberg says, in reality, they've been a bad deal.
JEFFREY HESS, BYLINE: I'm Jeffrey Hess in Jackson, Mississippi which is one of the 34 states letting the federal government take the lead in establishing a health insurance exchange. Heavy web traffic and software problems have made it nearly impossible to use the new web site since it opened last week.
MEREDITH STARK: Why I keep trying is because this is something we need.
Growing up, Barbara Handelsman often felt out of step with her family.
"When I was really little, I thought my sister always had all the power because she was pudgy and cute, where I had all elbows and knees," Barbara says. "I was so shy. I had no idea how to be the popular kid, and so I felt incompetent when it came to trying to be an A+ anything."
Grand Canyon National Park is closed for the government shutdown, but tourists determined to see it can take in views from reservation land. The Hualapai Tribe owns Grand Canyon West, where visitors can venture onto a Plexiglas horseshoe walkway that stretches out over the chasm below.
On the east side of the Grand Canyon, visitors are flocking to the Navajo Nation, where Nita Rodriguez gives a tour.

These torsos were printed in layers of biodegradable plastic. The original sculptures reside at the Louvre in Paris.
On Thursday, President Obama met with Senate Democrats. Then he met with House Republicans. And White House staff members continued talks with their counterparts from the House GOP leadership. All that talking just a day after there was radio silence between the two parties. One strong possibility for the change in attitudes is a new NBC/Wall Street Journal poll that shows that the majority of Americans blame Republicans for the ongoing government shutdown and just 20 percent of people approve of the Republican party.
The government shutdown is likely to mean an early death for thousands of mice used in research on diseases such as diabetes, cancer and Alzheimer's.
Federal research centers including the National Institutes of Health will have to kill some mice to avoid overcrowding, researchers say. Others will die because it is impossible to maintain certain lines of genetically altered mice without constant monitoring by scientists. And most federal scientists have been banned from their own labs since Oct. 1.
