Canadian officials are investigating an incident in which a driverless van traveled across the runway at Toronto's Pearson International Airport, at the same time an Air Canada flight was landing late Monday night. After the plane's pilots reportedly ignored commands to pull up, the jet "narrowly missed" the van, investigators say.

Scientists peering into the atmosphere of a giant planet 130 light years away believe their findings bolster one theory of how solar systems form.
The planet, orbiting the star HR 8799, is part of a solar system containing at least three other "super-Jupiters" weighing in at between five and 10 times the mass of our own Jupiter. The nearby system features a brash, young 30-million-year-old star (by contrast, our Sun is in midlife at about 4.5 billion years old).
On Friday, Pope Francis paid a heartfelt tribute to his predecessor Benedict XVI, saying his faith and teaching had "enriched and invigorated" the Catholic Church and would remain its spiritual patrimony forever.
Francis offered the respects during an audience with the cardinals who elected him to succeed Benedict, whose resignation set in motion the extraordinary conclave that brought the first prelate from the New World and the first Jesuit to the papacy.
Joshua Landis, the Director of the Center for Middle East Studies at the University of Oklahoma, says the hope among many Catholics is that the Church moves away from such strong European influence.

And the Bushes just keep on coming.
In recent memory, there was George H.W. Bush, 41st president of the United States. Then there was George W. Bush, 43rd president. And now there's John Ellis "Jeb" Bush, who may want to become the 45th president.
Jeb is sending mixed signals: Tonight he is a keynote speaker at a Conservative Political Action Conference dinner, but he has asked that his name be removed from CPAC's 2016 presidential straw poll.
Does Jeb have what it takes to be the next president of the United States?
Reporting in the journal Nature Physics, William Irvine and Dustin Kleckner, physicists at the University of Chicago, have created a knotted fluid vortex in the lab — a scientific first, they say. The knots resemble smoke rings — except these are made of water, and they're shaped like pretzels, not donuts. Understanding knottiness has extra-large applications, like understanding dynamics of the sun.

Just last week AIDS researchers were excited about a Mississippi toddler whose blood has remained free of HIV many months after she stopped getting antiviral drugs – what doctors call a "functional cure."
That's one of the questions being debated as Republicans — like all parties that have lost a national election — plot their comeback.
Some think they need to take a new tack on issues such as immigration in order to appeal to changing times and demographic changes. Others believe that the GOP's core conservative principles are still political winners, if delivered in a more convincing manner than was the case during last year's presidential race.
The NHL will shuffle its teams before next season, moving from three divisions in each conference to a total of four divisions in the Eastern and Western Conferences. The league's owners approved the plan Thursday; the players' association gave its OK last week.

A federal appeals court has rejected an effort by the CIA to deny it has any documents about a U.S. drone program that has killed terrorists overseas, ruling that the agency is stretching the law too far and asking judges "to give their imprimatur to a fiction of deniability that no reasonable person would regard as plausible."
