If you happen to spend Christmas Eve in Canada — especially Québec — you might lucky enough to be invited to a festive dinner after midnight mass. The feast is an old tradition from France called revellion, and it's something to look forward to after a long day of fasting.

"They'll have a huge feast, with sweets and lobster and oysters, everything," says Thomas Naylor, executive chef to the Canadian ambassador to the U.S. "But, in Quebec at least, you'll always have tourtière. It will be the center of the reveillon."

After experiencing chest pains, Britain's Prince Philip, the husband of Queen Elizabeth II, has been hospitalized.

The AP reports:

Tens of thousands are expected on the streets of Moscow tomorrow. As The Guardian reports, 50,000 have said they will show up on "Moscow's Sakharov Prospect, named after the late leading Soviet dissident Andrei Sakharov," and thousands more will march across the country.

It took 40 years for Bill Conlin to write his way into baseball's Hall of Fame — but just one newspaper story for his career to unravel. Conlin stepped down from his job at the Philadelphia Daily News this week, hours before its sister paper, the Inquirer, published a lengthy investigation into charges that Conlin had sexually abused children in the 1970s. The alleged victims say they were emboldened to come forward by the child sex abuse scandal at Penn State.

When makers of acetaminophen for infants said back in May that they were reducing the strength of the medicine so it would be less likely that babies would be accidentally given too much, it all made sense.

Some infant acetaminophen had as much as 80 milligrams of acetaminophen in a milliliter, while products for older children had less than half that.

Scientists have found that pigeons are much smarter than we give them credit for and can be taught some complex abstract math. This is stunning because it's trait that has only been shown in primates. But according to a report in the current issue of the journal Science, researchers were able to teach pigeons abstract rules about math.
