Cuba talks

U.S. and Cuban officials are starting a second day of historic face-to-face talks. Yesterday, the negotiations got off to a rough start, as the diplomats tackled the issues of immigration and the Cuban Adjustment Act. CBS News correspondent Manuel Bojorquez reports today’s discussions are expected to focus on re-establishing the U.S. embassy in Havana and reopening the Cuban embassy in Washington.

Close Gitmo?

President Obama pledged just this week at his State of the Union address that he’d make good on a promise that goes back to his first day in office: shuttering the U.S. military prison in Cuba at Guantanamo Bay. CBS News correspondent Margaret Brennan reports that, while fulfilling that promise has eluded the president, he’s making good progress on emptying the facility. But key Republican senators are trying to halt all transfers.

“Cop-watching”

As the debate over police-related violence persists across the country, some critics have taken it upon themselves to monitor law enforcement across America, increasingly turning to a controversial tactic known as cop-watching. Some just carry cameras, but, in a town just outside Dallas, there is a group of activists who cop-watch while openly carrying firearms.

Cop cleared?

Federal civil rights charges are not expected to be filed against the white police officer who shot and killed an unarmed black teenager in Ferguson, Missouri, last summer. Law enforcement officials confirm to CBS News Justice Department correspondent Bob Orr that the FBI has completed its investigation into the fatal shooting by former Ferguson police officer Darren Wilson of 18-year-old Michael Brown, and the bureau has forwarded its recommendations to the Justice Department, with “no charges expected.”

Third time?

It was just starting to look like Mitt Romney was settling in for a quiet life as a one-time GOP nominee, but when former Florida Gov. Jeb Bush announced he would actively explore a presidential bid, it set off a competition for the same donors Romney would need if he embarks on another White House run. So a few weeks ago, Romney ensured his name would remain on the list of 2016 contenders, telling potential donors he is considering a third presidential bid. But how are his chances now?

Mystery goo

A mysterious substance is killing hundreds of birds along a northern California shore. Scientists have factored out petroleum, fish and vegetable oil as the culprit. As CBS News correspondent John Blackstone reports, just what the mystery goo is remains anyone’s guess.

Vaccination gap

Most children born after 1971 received a measles, mumps and rubella vaccine. It requires two doses to be 99 percent effective. Doctors say those born before 1957 likely have been exposed to the virus and are immune. Those born between 1957 and 1971, when vaccines weren’t as reliable, should check with their doctors to see if they’ve been properly vaccinated.

XPrize

The criteria for winning the grand $20 million Google Lunar XPrize seems fairly straightforward: Land on the moon, cross a distance of 500 meters and send back high-definition footage to Earth along the way. Most of the teams in the competition are building rovers to do that. The Mountain View, California-based Moon Express team, however, is taking a rather different approach that does not use a rover at all.
