A lot has changed since 2012 — four years after he ran against President Obama, Mitt Romney received cheers at the Democratic National Convention.

Romney appeared in a video that featured prominent Republicans and conservatives commenting on their opposition to Trump. He wasn't the only one to get applause — Sen. Lindsey Graham (R-S.C.) and former New York Gov. George Pataki were also well-received. After the video played, John Hutson, a retired rear admiral and former judge advocate general, came onstage, and announced, "Unlike Donald Trump, there are two things that I know an awful lot about: Law and order." He called Trump out for "endorsing torture at a minimum" and inviting Russia to hack a U.S. entity. "It's embarrassing enough that he's the face of one of our political parties," Hutson said. "The real disaster would be if we let Donald Trump become the face of the country we love."

Hutson urged people to listen to the more than 120 Republican national security leaders who have warned that Trump would "make America less safe," and brought up Trump's comments on Sen. John McCain (R-Ariz.). "I served in the same Navy as John McCain," he said. "I used to vote in the same party as John McCain. Donald, you're not fit to polish John McCain's boots." The room erupted in more unlikely cheers, this time not for McCain the Republican, but McCain the war hero. Catherine Garcia

Jane Fonda may not know where she's going, but she knows where she's been.

The Academy Award-winning actress gives audiences an intimate look into her life in the first trailer for her HBO documentary, Jane Fonda in Five Acts. Directed by Susan Lacy, the film discusses Fonda's upbringing with her famous father Henry Fonda, her rise to fame, and her political activism.

Fonda opens up in the documentary, revealing her internal struggle to please her father and become whatever he wanted. "I never felt real. I just thought, 'I gotta find who I really am,'" said Fonda.

Sundance Film Festival was the first to premiere Jane Fonda in Five Acts earlier this year, reports Entertainment Weekly. The film was compiled from more than 20 hours of interview footage with Fonda, along with sit-downs with Lily Tomlin, Sam Waterson, Robert Redford, and more. HBO is set to release the film Sept. 24.

It may have taken Fonda some time to figure out who she was outside of her famous family, but she knows now: "I am what I am." Watch the full trailer below. Amari Pollard

Children spend less and less time outdoors and in "free play" time, and it has damaging effects on cognitive development.

About 30 percent of kindergarten classrooms in the U.S. no longer send kids out to recess, a Monday report from the American Academy of Pediatrics found, and the increasing focus on academics and structured enrichment activities is tied to anxiety and lower creativity later in life.

As Stat News reports, free play helps children learn, relieve stress, and develop new skills. Only about half of preschool-aged kids get daily playtime outside with a parent, even though unstructured play is key to cognitive and social development. Between 1981 and 1997, young children lost 12 hours per week of free time, the report explains, citing increased homework loads and media distractions. "Play is not frivolous," the AAP report explains. "It enhances brain structure and function and promotes executive function ... which allow us to pursue goals and ignore distractions."

The report recommended that doctors talk with families about finding time to allow children to be creative and maintain agency over their activities. Researchers acknowledged "parental guilt" that "has led to competition over who can schedule more 'enrichment opportunities' for their children," and that not all children live in safe areas for outdoor play, but emphasized the importance of finding ways to help kids develop the same skills. "Play and learning are inextricably linked," the AAP reports. Summer Meza

Michigan's top health official will go to trial for manslaughter charges in the wake of the Flint water crisis.

Arguments concluded in July over whether Nick Lyon, the state director of health and human services, would face a manslaughter trial in connection to the crisis, The Associated Press reports. Michigan's attorney general claimed Lyon didn't alert citizens to the outbreak soon enough, and on Monday a judge agreed to send Lyon to trial.

Two men died from Legionnaire's disease after the water supply in Flint, Michigan, was contaminated following the city's decision to switch water sources. Faulty old pipes contaminated the city's water, which has remained contaminated since 2014. After a 10-month preliminary hearing, Lyon was charged with two counts of involuntary manslaughter and one count of misconduct in office over the two deaths, per ABC affiliate 12 News. Lyon is the highest ranked of 15 officials criminally charged in relation to the water crisis, MLive says. Kathryn Krawczyk

Lunar vacations are inching closer to reality.

Astronomers have discovered ice deposits on the moon's north and south pole, a report published by the National Academy of Sciences on Monday reveals. The findings are the first "direct and definitive evidence" of water ice, the report explains. If humans return to further explore the moon, the frost patches could prove to be a source of water.

The Earth's moon, along with Mercury and the dwarf planet Ceres, were long thought to hold water on their airless surfaces. Scientists found ice deposits on the other bodies, but they previously could only identify ice under the moon's surface and craters that might be cold enough to produce surface ice.

Now, data from India's Chandrayaan-1 probe shows that frost has accumulated above the moon's rocky floor, per The Guardian. The ice comes in flakes latched to grains of moon dust and only appears in shadowed craters that don't break -261 degrees Fahrenheit, crushing everyone's hopes for a SpaceX spring break.

Scientists have long theorized about the origins of life on Earth. But thanks to new research from England's University of Bristol, there are some new clues to factor into the question of how our world came to be.

For a long time, our best bet at figuring out when life developed on our home planet was to analyze fossils, the earliest of which gave us evidence of life as old as 4 billion years ago. But in a study published Monday in the journal Nature Ecology & Evolution, scientists posit that life may be up to hundreds of millions of years older than that.

Researchers took a closer look at the fossils we've already discovered — namely, their DNA, Phys.org reported. They analyzed genetic data until they were able to build a theoretical timeline of when life evolved into those organisms. From there, they traced ancient microbes' lineage to a "Last Universal Common Ancestor" of all life, or "LUCA," said study co-author Davide Pisani. The data found through that DNA is much more reliable than fossil evidence alone in proving evolutionary links, said the study's lead author, Holly Betts.

Around 4.5 billion years ago, Earth was impacted by another planet called Theia, Metro explained. This collision "sterilized" Earth and sent a chunk of space rock hurtling into orbit around us — what we now know as the moon. Per the scientists' findings, it wasn't long after that that the "LUCA" originally lived.

Although that might be the origin of life on Earth, it's worth noting that the branch of the evolutionary tree that led to humans is much, much younger. "We belong to a lineage that is billions of years younger than life itself," Pisani explained. Read more about these new discoveries at Metro. Shivani Ishwar

The Eagles' greatest hits are now the entire music industry's greatest hits.

Their Greatest Hits 1971-1975, a compilation of Eagles songs like "Take It Easy" and "Tequila Sunrise," is now the best-selling album of all time, reports The Associated Press, with 38 million copies sold.

The Recording Industry Association of America on Monday announced that The Eagles' album, released in 1976, had surpassed Michael Jackson's Thriller, the longtime record holder. Thriller now holds second place, while The Eagles' 1977 album Hotel California is in third place.

Back in 2007, The Eagles explained that they had never wanted a Greatest Hits album in the first place. "None of us had a say in the decision," lead guitarist Don Felder told the Times Online. Clearly, the decision paid off: The album is now certified 38x platinum.

Bandmate Don Henley, who still tours with the band, said in a statement that the band is "grateful for our families, our management, our crew, the people at radio and, most of all, the loyal fans who have stuck with us through the ups and downs of 46 years. It's been quite a ride." Summer Meza

This year's hot back-to-school trend? Bulletproof backpacks, jackets, and undershirts. Yes, MC Armor has designed reinforced clothing perfect for sending your precious kids off to learn, and the line received some airtime during Monday's Mornings with Maria on Fox Business Network.

The segment started with an Oprah-esque pan over sparkly neon backpacks, with the 2009 pop hit "Bulletproof" playing in the background. Host Maria Bartiromo then took over, picking up a bag and gushing that it didn't "even feel heavier than a regular backpack" to MC Armor manager Carolina Ballesteros Casas.

Casas then revealed the backpack's secret strength: a hard board that can also be removed and used as a shield. "Pediatricians say kids, before 15, they don't have fat, they don't have enough muscles, so they need to have hard ballistics," Casas explained.

Next up was what Bartiromo called a "fashion forward" bright red ballistic jacket. There's also a $1,500 white undershirt that's "very wearable under your suit," Bartiromo proclaimed. Watch the whole outrageous segment below. Kathryn Krawczyk
