It's still a good idea. But it won't protect you against heart disease.
Think flossing and brushing is helping to fight off heart disease and stroke? Think again.
An expert panel of dentists and cardiologists, writing in the American Heart Association journal Circulation, says there is no evidence that treating or preventing gum disease has any direct effect on heart health.
That's a big turnaround. For the past decade, the medical establishment has been telling people that cardiovascular disease can be caused by poor oral hygiene. Why the change?
Syrians walk through a badly damaged neighborhood in the central city of Homs on Sunday. Despite a declared cease-fire, fighting has continued in a number of Syrian cities, and peace efforts are at risk of collapsing.
In the final scenes of the classic film Lawrence of Arabia, the Arab rebel fighters are wrapped up with internal, petty squabbles in Damascus as the great powers maneuver for the future of Syria.
Now, nearly a century after the events depicted in that movie, there's a similar Lawrence of Arabia moment playing out in Syria.
In a letter to the United Nations Security Council, Secretary General Ban Ki-moon says the Syrian government is not living up to its end of the bargain on a week-old cease-fire deal.
Ban says the government has failed to keep its pledge to withdraw troops and heavy weapons from cities, but adds that he still thinks there is "opportunity for progress."
The Secretary General's letter comes as the U.N. and Syria apparently worked out details of an observer mission to monitor the shaky deal meant to end more than a year of bloodshed that has killed an estimated 9,000 people.
Proponents of the death penalty often argue that the threat of being executed acts as a deterrent that prevents people from committing murder. But those who oppose capital punishment challenge that claim. And some researchers argue that state-sanctioned execution might actually increase homicide rates.
Now, a panel of independent experts convened by the prestigious National Research Council has taken a look at this question and decided that the available research offers no useful information for policymakers.
Oil field workers drill into the Gypsum Hills near Medicine Lodge, Kan., on Feb. 21. The Environmental Protection Agency announced new rules Wednesday to control the problem of air pollution coming from wells being drilled by the booming oil and natural gas drilling industry.
The Environmental Protection Agency's new air pollution rules for the oil and gas industry may seem like odd timing, as President Obama has been trying to deflect Republican criticism that he overregulates energy industries. But the rules weren't the Obama administration's idea.
Several years ago, communities in Colorado, New Mexico and Wyoming complained about air pollution from natural gas booms in their local areas.
We imagine the lobbyist stalking the halls of Congress trying to use cash to influence important people. But it doesn't always work that way. Often, the Congressman is stalking the lobbyist, asking for money.
Many Web users have little idea about how, or when, they're being tracked. In this 2011 photo, Max Schrems of Austria sits with 1,222 pages about his activities on Facebook — the company gave him the file after he requested it under European law.
Fairview Developmental Center in Costa Mesa, Calif., is a sprawling facility of offices, residential buildings and therapy rooms set between a noisy boulevard and a golf course.
Some 400 people with developmental disabilities live at Fairview. And while minor scratches and bruises are not uncommon for these patients, over the years, the center has seen scores of serious injuries and even deaths.
Fairview is one of five state-run developmental centers in California — homes for people with developmental disabilities who are unable to care for themselves.
