Researchers have discovered yet another benefit of exercise: It not only helps skin look younger, but may even reverse skin aging in those who begin exercising later in life.

According to The New York Times, scientists at McMaster University in Ontario, Canada, found that mice who were bred to age prematurely became frail and demented and lost their fur when they remained sedentary. Mice that had access to running wheels had an opposite response: They maintained healthy hearts, muscles, brains, and reproductive organs, and their fur never turned gray.

Researchers then turned to humans. They tested the skin samples of 29 volunteers — males and females, between the ages of 20 and 84 — and had half perform at least three hours of moderate or vigorous physical activity a week, while the others exercised for less than an hour each week. After taking samples of skin, researchers discovered that the men and women older than 40 who exercised frequently had a thinner and healthier stratum corneum (the part of the skin you see and feel) and thicker dermis layer, which looked more like that of a 20-something.

Scientists are still trying to figure out how exercise changes the skin composition, but they did discover that the skin samples of those who exercised more had high levels of a myokine — a substance created by active muscles that enters the bloodstream and starts changes in cells — called IL-15. While they still don't have all the answers, researchers are amazed by what they've discovered so far. "It is astonishing to consider all of the intricate ways in which exercise changes our bodies," says Dr. Mark Tarnopolsky, a professor of pediatrics and exercise science at McMaster who oversaw the study.

Hacked emails published Saturday by WikiLeaks see Hillary Clinton's campaign weighing the pros and cons of having their candidate give a major speech on race issues in America, the Associated Press reported Sunday.

In a conversation in February of this year, Clinton's chief speechwriter, Dan Schwerin, emailed other staff to suggest such a speech could show Clinton's "sustained and comprehensive commitment" to minorities. However, he wrote, the speech could also "unintentionally end up elevating questions that aren't yet being widely asked and introduce new damaging information, especially [Clinton's use of the term] super predator, to a lot more voters."

Schwerin concluded that "if we're slipping fast [in the race against Sen. Bernie Sanders], maybe it's worth rolling the dice and doing the speech. If we're holding relatively steady, maybe we see if we can ride this out without doing the speech."

Clinton did end up giving a speech on race issues in Harlem on Feb. 16. At the time, Sanders was rising rapidly in the polls, from an average of 35 percent support the day before the speech to 42 percent three days later. Bonnie Kristian

Donald Trump's campaign manager, Kellyanne Conway, joined Fox News host Chris Wallace on Sunday to discuss whether Trump can plausibly accrue the 270 Electoral College votes he needs to win the White House.

After Wallace asked what Trump's "realistic path" to that victory could be, the famously smooth-talking Conway insisted with a rapid-fire list of states that the race is not over yet. Clinton is "still under 50 [percent] everywhere," Conway argued, despite an advertising budget that far exceeds Trump's ad spending.

Lapsed voters and first-time voters are enthusiastic about her candidate, Conway added, but likely to be underrepresented in polling data. "We're not giving up," she concluded. "We know we can win this, and we are certainly not acceding to the same chattering class that's been wrong about Donald Trump for about a year and a half." Watch the full exchange below.

Spain's Socialist Party on Sunday cleared the way to ending nearly a year of political deadlock by abstaining from a parliamentary vote which was then able to confirm Prime Minister Mariano Rajoy of the conservative People's Party (PP) for another term.

The abstention decision follows national elections in December and June which left no single party or coalition with a governing majority. The most recent election saw Rajoy's party take a plurality while the Socialists, the runner-up, lost five seats in parliament. A third general election would have been scheduled soon absent today's shift, and the Socialist Party was worried they might lose additional seats in the third vote.

"We went to win the elections, but since that didn't happen, we need that there is a government to act as the opposition," said Socialist interim party head Javier Fernandez of his party's unusual decision. Without a sweeping mandate from voters, Rajoy has said he must "work day to day, with humility and patience" to pursue his legislative agenda. Bonnie Kristian

While conventional wisdom suggests income level is the greatest determining factor in white voters' support for Hillary Clinton or Donald Trump (she the elite insider, he the voice of the beleaguered working class — or rich Republicans facing off against poor Democrats) a new analysis from FiveThirtyEight suggests religion and education level are both far more important.

"Roughly speaking," the report summarizes, "a white voter will lean left if she is 'more college than church' and will lean right if she is 'more church than college.'" For those who fall in the middle of each spectrum, the third most predictive factor — whether a person lives in a more urban or rural area — settled the matter, with rural voters preferring Trump and urbanites going with Clinton.

As for income, the pollsters note it was actually "the least predictive of white voter support" of all seven demographic factors analyzed. The voting habits of white voters will be subject to extensive scrutiny in the run-up to Election Day, as overwhelming minority support for Clinton means Trump would rely primarily on white swing voters to win.

Donald Trump was endorsed by the Las Vegas Review-Journal in an editorial published Saturday night, his first serious newspaper endorsement of the general election. The bulk of the endorsement pitch turned on Supreme Court vacancies, arguing Hillary Clinton must not be permitted to fill those seats.

"Mr. Trump represents neither the danger his critics claim nor the magic elixir many of his supporters crave," the article says. "But he promises to be a source of disruption and discomfort to the privileged, back-scratching political elites for whom the nation's strength and solvency have become subservient to power's pursuit and preservation."

Trump was previously only endorsed for the general election by The National Enquirer, while most paper endorsements have gone to Clinton. Even Libertarian nominee Gary Johnson still easily outpaces Trump in newspaper support, with the backing of notable outlets like the Chicago Tribune, The Detroit News, and more. Bonnie Kristian

The United States and Iran aren't the friendliest pair on a national level, but Iranian President Hassan Rouhani, who has taken a more conciliatory stance toward the West than others in his country's leadership, feels America's pain on having to pick between two historically unpopular presidential candidates.

"America claims it has more than 200 years of democracy, and they have had 50 presidential elections, but there is no morality in that country," Rouhani said in a speech Sunday. "You saw the presidential debates, how they talk ... how they accuse and mock [each other]."

He recounted a recent episode in which he was asked by a fellow head of state whether he preferred to see Hillary Clinton or Donald Trump in the White House. "I said should I prefer bad over worse or worse over bad?" Rouhani recalled, declining to specify who is "bad" and who is "worse." Bonnie Kristian

"Hey, buddy," Tom Hanks said at the beginning of his heart-to-heart with the oldest Hanks child — the United States of America — in his Saturday Night Live monologue. Hanks was recently named "America's dad" on a magazine cover, so he decided to use his SNL intro to have a little chat with a nation he's noticed is confused and even scared of all the changes happening inside.

Hanks mostly struck an encouraging tone, as any good parent would do. "Remember when you went though that Depression? This is nothing!" he said. "You're just growing up. You're in an awkward phase."

But he had some tough love, too. That national debt, for instance — don't expect dad to pay it off. "I'd like to help you out," Hanks said, "but if I do, you're never gonna learn. Also, I don't have $19 trillion. I have $230 million." Also, everyone can smell the weed, champ.

Watch the whole chat below. Bonnie Kristian
