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.

The U.K.'s Houses of Parliament were hit with a cyberattack Friday evening consisting of "unauthorized attempts to access parliamentary user accounts," a representative of Parliament said Saturday. Members of Parliament were informed of the situation Friday night when they had difficulty accessing their email accounts remotely.

"We are continuing to investigate this incident and take further measures to secure the computer network," the representative said. "We have systems in place to protect member and staff accounts and are taking the necessary steps to protect our systems."

Monday begins the Supreme Court's final week before its current term ends and summer break begins. SCOTUS is expected to hand down several major decisions in the next few days — among them its ruling on President Trump's stalled travel ban — but rumors are swirling that this Monday could see a retirement announcement from Justice Anthony Kennedy, too.

"Sources close to Kennedy say that he is seriously considering retirement," CNN reported Saturday, though "they are unclear if it could occur as early as this term." Kennedy's departure would give President Trump his second SCOTUS nomination after the successful appointment of Neil Gorsuch to replace the late Antonin Scalia.

Kennedy has long served as a swing vote on the court, sometimes siding with the progressive wing — as in the landmark gay marriage case, 2015's Obergefell v. Hodges — but often joining the conservatives on issues like gun control and campaign finance. Kennedy will turn 81 in July and has served on the court since 1988 after being nominated by President Reagan. Bonnie Kristian

The tiny Gulf nation of Qatar has rejected a list of 13 demands issued by Saudi Arabia and other neighboring Arab states Thursday as a condition for restoring diplomatic ties. The Saudi-led group of countries isolating Qatar claims the country is supporting terrorism, an allegation Qatar denies.

Qatari Foreign Minister Sheikh Mohammed bin Abdulrahman al-Thani said in a statement the demands should have been "reasonable and actionable" as well as "measured and realistic," quoting comments from top U.S. and U.K. diplomats. "This list does not satisfy that [sic] criteria," he added.

It was never very plausible Qatar would answer other than it did. The "extent and scale of the demands appear designed to induce a rejection by Qatar," notes The Atlantic, "and a possible justification for a continuation, if not escalation, of the crisis. The list, if accurate, represents an intrusion into the internal affairs of Qatar that would threaten its very sovereignty." Bonnie Kristian

Former governor of California (and Terminator star) Arnold Schwarzenegger teamed up with new French President Emmanuel Macron to take a swipe at President Trump on environmental issues Friday.

"I'm here with President Macron. We are talking about the environmental issues and a green future," says Schwarzenegger in the clip posted to Facebook and Twitter. "And now we will deliberate together to make the planet great again," adds a grinning Macron with a transparent reference to Trump's "Make America great again" slogan.

These antics come in response to Trump's decision to withdraw the United States from the Paris Agreement, the international climate accord both Macron and Schwarzenegger support. Bonnie Kristian

The United States and China have reaffirmed their mutual commitment to "strive for the complete, verifiable, and irreversible denuclearization of the Korean Peninsula," Chinese state media agency Xinhua reported Saturday.

The statement comes after Secretary of State Rex Tillerson and Defense Secretary James Mattis hosted Chinese diplomats in Washington in an attempt to reach consensus on how to deal with increasing provocation from Pyongyang. Tillerson indicated earlier this week he is asking China, which is North Korea's primary trading partner, to increase its political and economic pressure on the Kim Jong Un regime. Bonnie Kristian

Russian interference in the 2016 election "is really the political equivalent of 9/11 — it is deadly, deadly serious," said former Undersecretary of Defense Michael Vickers, who served in the Obama administration, in an NBC News interview Saturday. "The Russians will definitely be back, given the success they had," he added. "I don't see much evidence of a response."

Vickers' comments come one day after The Washington Post's comprehensive report detailing former President Obama's inaction in response to Russian election interference in 2016. President Trump and congressional Democrats have also criticized the Obama administration's "inadequate" response.

Builders misused a combustible cladding to cover the sides of London's Grenfell Tower, the apartment building where 79 people were killed in a massive fire last week, Reuters reported Saturday. The material was intended for buildings a maximum of 10 meters tall, about the height of firefighters' ladders; Grenfell was more than six times that height.

Email correspondence reveals the cladding manufacturer, Arconic, sold the siding knowing it would be used inappropriately. "While we publish general usage guidelines, regulations and codes vary by country and need to be determined by the local building code experts," Arconic said in a statement to Reuters pledging to "fully support the authorities as they investigate this tragedy."

British authorities are now reviewing other high-rises for combustible cladding, and at least four buildings have been evacuated. "I know it's difficult, but Grenfell changes everything and I just don't believe we can take any risk with our residents' safety," said Georgia Gould, leader of the Camden Council, which evacuated the four high-rises Friday. "I have to put them first." Bonnie Kristian
