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.

Democrat Hillary Clinton spent Saturday morning at an FBI office near her home in New York receiving her first classified briefing as a nominee for president.

The two-hour meeting came about a week and a half after Republican Donald Trump received a similar intelligence update, attended by New Jersey Gov. Chris Christie and retired Lt. Gen. Michael Flynn. The briefings are conducted by staff of the Office of the Director of National Intelligence and held in special rooms called Sensitive Compartmented Information Facilities.

Though such meetings have been used to prepare nominees for a smooth transition into office for more than half a century, opponents of both candidates this election cycle have questioned their respective fitness to receive such valuable information. Clinton's critics pointed to her private email server scandal as evidence that she cannot be trusted with classified documents, while Trump's detractors suggested he is too loose-lipped to handle sensitive data.

If you have clear skies just after sunset on Saturday, August 27, look west to see Venus and Jupiter so close on the horizon they almost appear to merge into a single light.

This rare astronomical event is called an "appulse," which is when two celestial bodies appear from Earth's vantage point to approach each other as closely as possible — in this case, with less than one degree between the two planets.

Venus and Jupiter will not come this close again for nearly five decades — the next comparable conjunction will appear in 2065 — and Saturday's light show will be bright enough to view with the naked eye, weather permitting. Bonnie Kristian

Donald Trump took to Twitter Saturday morning to boast that African-American voters will support him come Election Day — and had he stopped there, it would have been just another example of Trump's awkward minority outreach efforts.

Instead, however, he cited the fatal shooting of Nykea Aldridge, cousin of Chicago Bulls shooting guard Dwyane Wade. The mother of four was killed by stray gunfire Friday, and Trump — while misspelling Wade's first name — said her death is one reason black Americans will give him their votes.

Trump was roundly criticized for his tweet after it went live. Actor Don Cheadle tweeted, "You are truly a POS," while The Washington Post's Philip Bump nailed the post's inappropriate tone: "It comes off not as a thoughtful statement of concern for a tragedy that needs to be fixed and more as an attempt to leverage a murder into a campaign slogan."

At least 17 Kyrgyz migrant workers were killed and four more injured Saturday when a printing warehouse in Moscow, Russia, caught fire. The blaze was put out after two hours.

The fire was caused by a broken lamp on the first floor, said Ilya Denisov, chief of Moscow's emergency services, and then spread upstairs through an elevator shaft. The victims are all believed to be young women who were trapped while putting on their work uniforms.

"Most of them were in Moscow to earn money," said Abdygani Shakirov, who works at a local Kyrgyz community organization. "They were in the dressing room and were unable to get out. The smoke had blocked the exit." Bonnie Kristian

If you're ever stranded on a desert island, writing "SOS" in giant letters in the sand actually can help — or, at least, it helped a pair of boaters rescued by the U.S. Coast Guard from an uninhabited island in Micronesia on Friday.

The pair began their journey on Wednesday, August 17, and were expected to arrive at their destination one day later. Instead, they landed on the empty island near the Chuuk Lagoon on Friday, August 19, and survived on limited supplies for a week until the SOS was noticed by a U.S. Navy plane. Before the SOS was spotted, rescuers searched some 17,000 square miles without success. Bonnie Kristian

The United States and Russia are close to reaching agreement on national ceasefire in Syria, Secretary of State John Kerry said Friday, but have yet to sign a deal. Following talks with Russian Foreign Minister Sergey Lavrov in Geneva, Kerry said there are still "a few narrow issues to be resolved" before a lasting accord can be reached.

"We don't want to have a deal for the sake of the deal," he explained. "We want to have something done that is effective and that works for the people of Syria, that makes the region more stable and secure, and that brings us to the table here in Geneva to find a political solution."

The U.S. and Russia previously reached a ceasefire agreement in February, but that temporary peace collapsed by April. Bonnie Kristian

Donald Trump's personal physician, Dr. Harold Bornstein, wrote a letter in December declaring Trump the "healthiest individual ever" to have a shot at the presidency, with "astonishingly excellent" test results. Speaking publicly about the letter for the first time on Friday evening, Bornstein revealed he wrote it in "five minutes" while his limo driver waited outside. He did not proofread the letter.

As for the remarkably Trumpian style of the note, Bornstein insisted he wrote it himself, but admitted he "might have picked up [Trump's] kind of language and then interpreted it as my own." Bornstein also justified his claim about Trump's unparalleled health by saying all past presidents "are either sick or dead" — which I guess is at least half true, though you can't really fault guys born 200 years ago for failing to make it to 2016.

Watch Bornstein's remarks below, including the little giggle he can't resist while labeling Trump's mental health "excellent." Bonnie Kristian
