-- and its wider implications for human mental health treatment -- was found in their poop, per new findings published in Behavioural Brain Research.Rats are better drivers when they're mentally stimulatedKelly Lambert, study author and head of the University of Richmond's Lambert Behavioral Neuroscience Laboratory, trained two groups of young rats: One bunch raised in an "enriched environment" with toys, ladders, balls and pieces of wood designed to spark mental stimulation, and another reared in a standard, unexciting lab cage.The rats learned to enter a custom "rat-operated vehicle," or ROV, adorably constructed from a one-gallon plastic container turned on its side.Once inside, the rat racers would stand on an aluminum plate and press on a copper bar that would trigger the wheels' motor. They'd hold down on the bar until they propelled their tiny car to the end of their enclosure, where they collected their reward: Froot Loops.When it came time to drive, the rats who played with ladders, balls and toys were more adept at operating and steering the ROV, thanks to the neuroplasticity (their brains' ability to change over time) triggered by their environment. Their unstimulated cage counterparts effectively "failed their driving test," Lambert said.Hormones found in their feces showed improved emotional resilienceIn sifting through their fecal matter, Lambert found both groups of rats trained to drive secreted higher levels of corticosterone and DHEA, hormones that control stress responses.Corticosterone is a hormone animals could secrete in high-stakes scenarios like running from a wild animal or defending themselves from predators, but it can also be expressed in lower-risk tasks like doing taxes or worrying about a loved one (though rats likely aren't advanced enough to form a government, let alone impose taxes on fellow rats).DHEA acts as a sort of "buffer," Lambert said, when corticosterone becomes toxic -- that is, when it can't be turned off in a reasonable amount of time, creating prolonged stress.It's evidence that mastering a complex task, like driving a car, bolstered the rats' emotional resilience."It is likely that driving gives the rats a sense of control over their environment," she said. "In humans, we would say that it enhances a sense of agency or self-efficacy."What have rats got to do with human health?The brains of humans and rats share nearly all of the same areas and neurochemicals -- they're just smaller in rodents. And though humans are certainly more complex than rats, Lambert said there are "universal truths" in how both species' brains interact within their environment to maintain optimal mental health.So these results have implications for human health, too (and no, they don't mean rats will drive alongside people in tiny lanes on highways). Emotional resilience is one of the first lines of defense against mental illnesses like depression, she said, and learning what behaviors build that up could clue physicians in on how to treat those illnesses in humans.It's a concept Lambert refers to as "behaviorceuticals," activities that release hormones that can ward off prolonged stress brought on by corticosterone."Anything that reduces stress can build resilience against the onset of mental illness," she said.The activity can be something as simple as knitting, or in rats' case, learning to drive a car. Just engaging hands, paws and brains of varying sizes can enhance a participant's sense of control. 3489

You've probably heard the story of 6-year-old Bridger Walker, the Wyoming boy who protected his sister from a dog attack. The social media post showing the boy’s scars went viral.Saturday, he was in Denver at IT’SUGAR Candy Store, where he got to go on a candy shopping spree with his siblings.Bridger is smiling for a big reason.“Because I like candy,” he said.The 6-year-old who saved his little sister from a dog attack a couple of weeks ago got a candy shopping spree at IT'SUGAR Candy Store in Denver. They are just the latest in a long line of people reaching out to thank him.“It's been surreal," his father, Robert Walker, said. "We never expected this to go viral the way it did. We were literally just hoping for a postcard or a letter or a shout out to boost our little boy's spirits.”Actor Chris Evans promised him a Captain America shield. Fellow Avengers, Tom Holland, and Robert Downey, Jr., reached out, wanting to reward a little, real-life hero.“He's always been protective of his little girl. She's always been his little princess, and she gets annoyed sometimes that he won't leave her alone. So, it didn't surprise us at all that he would jump in the way he did,” his father added.Bridger has received gifts of support from all over the world, but his parents say the attention hasn't gone to his head.The sugar rush may be the latest chapter for this little hero. One, the family is so thankful for.“The world's a good place, and that there are hundreds and thousands and millions of wonderful people in this world,” Robert Walker said.Bridger and his siblings can all share this experience together.“We're close, and this experience has definitely made us closer,” Robert Walker added.KMGH's Sean Towle first reported this story. 1760

Young people are notorious for skipping elections, and it's a problem voting advocates have tried solving for decades.This year, they had a big uphill battle, mobilizing future voters virtually.“Pre-pandemic, you and I would probably be interviewing in this beautiful student union of ours," said Armando Sepulveda II. “We would have candidates talking to students, meeting students.”A senior at San Diego State University, Sepulveda is Rock the Vote Chair at his school, working on getting as many students as possible registered to vote. “We were going into the dark because we didn’t have any pre-context of how we could handle a Rock the Vote campaign during a pandemic," said Sepulveda. They couldn’t hold large gatherings to register students to vote or hold candidate debates in auditoriums. On-campus posters were replaced with posts online.“We acknowledged that social media was a great platform to get apathetic students because regardless of what they’re doing during the day, they’re probably going to log onto Instagram at least once or twice," said Sepulveda.To keep students from scrolling past their message, Sepulveda's team focused on design, creating easy-to-read, digestible content. “We wanted to make it as simple and visually interesting as possible," he said. They conducted "Zoom-arounds," crashing club meetings to talk about propositions, how to get your ballot and making sure it’s counted. They also held community forums online with local candidates.“I think a lot of young people want to have a renewed sense in trust in the government, but in order to have that, you have to have people you trust elected," said Sepulveda. Sepulveda says after combining California and out-of-state students, they surpassed their goal of registering 1,400 students to vote. Researchers at Tufts University say youth turnout is surging in many states. More than 7 million young people have already voted early or absentee this election. 1958
