Objects found in Mozambique are being tested for any connections to MH370 and a knife found on O.J. Simpson's former property is being tested for any possible connection to his wife's murder.
Here's a look back at those stories and other highlights — in the form of five handy charts:
Super Tuesday is Super for Clinton, Trump
Republican Donald Trump and Democrat Hillary Clinton closed in on their party's presidential nominations by racking up big wins on Super Tuesday, although the rest of the field showed no signs of clearing the way for them just yet. Clinton won seven states — Virginia, Tennessee, Alabama, Georgia, Arkansas, Texas and Massachusetts. Trump scored also scored seven victories, winning in Massachusetts, Virginia, Tennessee, Alabama, Georgia, Arkansas, and Vermont.
NASA's Scott Kelly Returns to Earth
NASA celebrated a very big homecoming Tuesday as American astronaut Scott Kelly returned to Earth. He had spent almost a full year on the International Space Station floating 250 miles above the surface — setting a record for an American astronaut. All told, after adding up all of Kelly's missions over the years, he will have set the American record of 520 days in space.
Possible MH370 Part Found Off Mozambique
An object that could be debris from a Boeing 777 has been found off Mozambique and is being examined by investigators searching for missing Malaysia Airlines Flight MH370. The location where American adventurer Blaine Gibson found the possible debris from Malaysia Airlines Flight MH370 is consistent with theories about where the wreckage may lie, Australia's transport minister said Thursday.
Romney Lays Out Scathing Critique of Trump
Former Republican presidential nominee Mitt Romney delivered a scorching indictment of Donald Trump on Thursday, calling him a phony, a fraud, a misogynist and a bully who threatens America's future. Romney went on an epic take down of the Republican frontrunner, point-by-point, issue-by-issue, critiquing his business acumen, the amount he's worth, his ability to understand foreign policy and his temperament and his honesty.

Los Angeles police are testing a knife found a dozen years ago on land where O.J. Simpson once lived — but it is far from clear whether it has any connection to his wife's murder, a case that has remained open since the former football star was acquitted in 1995, multiple law enforcement officials said Friday.
