-- 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

in Terminal 4.The TSA says the incident happened Tuesday morning around 9:45 a.m. local time.In a press release, TSA said the man was unprovoked and attempted to rush through the security at Terminal 4.According to police documents, 19-year-old Tyrese Garner pushed his way past other passengers and charged through the metal detector before punching a TSA agent and knocking her to the ground.He reportedly punched four other TSA agents before he was subdued. Police officers arrived and arrested him on charges of criminal trespassing, assault and resisting arrest.Documents say he tried to resist arrest, kicking and writhing while refusing to be taken out of the terminal.One transportation security officer (TSO) was taken to the hospital and at least four others were taken to an urgent care facility. Their exact injuries and conditions are unknown at this time."Got done putting my shoes on and was walking down the hallway part there and all of a sudden I heard screaming and hollering," said witness Donnie Jones, who had just passed through security when the incident occurred.Jones said he's unsure what prompted the man to allegedly try and rush through the checkpoint."When he was coming over that counter...he was like jumping at somebody and you could just see a bunch of swinging and that and you couldn't really tell what was going on," he said. "I don't know what his deal was. It was just an unhappy guy rushing through there."Documents say Garner is from Texas and is mentally unstable. He was reportedly under the influence of drugs or alcohol at the time.Neither police nor TSA has released a motive in the incident.TSA released the following statement on the incident: 1694

— like Big Brother is very much watching. And such systems do dance a fine line between informative and intrusive. But they also could help mitigate the spread of a virus, and that could make the difference between having Michigan Stadium empty on a fall Saturday or having 100,000 fans rooting on the Wolverines again.Not everything will be as overt as barren concourses and empty seats, either. Most of the changes that colleges and teams are implementing will go unnoticed by those who settle in for the kickoff or first pitch.Premier League club Tottenham recently opened its new London stadium after spending millions to create more than 1,600 WiFi access points and 700 Bluetooth beacons, ensuring fans are able to utilize crowd-density apps and other technology. Many facilities are upgrading heating, cooling and ventilation systems to scrub air as it circulates through their buildings, while others are toying with the use of QR codes to monitor the health of their patrons.“We’re extrapolating off these trends that have already existed, and I think we’re going to kick-start into 2025 even though it’s only 2020,” said Jason Jennings, director of strategy and digital integration for the sports and entertainment group at Mortenson, which is wrapping construction on the Raiders’ new .4 billion stadium in Las Vegas. “The technology is going to be deployed much faster because of the value it has for the fan experience and public health.”Even the way facilities are cleaned will change. No longer will hosing down seats and sweeping up trash left by fans be enough. Venue giant ASM Global recently announced a new hygiene protocol for its 325 facilities worldwide, noting the importance of hewing to international health recommendations from the likes of the Centers for Disease Control and the World Health Organization.Few professional teams have been willing to divulge their reopening strategies, whether that be potential seating layouts or infrastructure upgrades. The rapidly changing social and political environment coupled with the unpredictable nature of the virus have made planning difficult. But the Miami Dolphins and Hard Rock Stadium recently committed to being the first public facility to receive a STAR rating from the Global Biorisk Advisory Council, which involves completing a rigorous program to help provide what Dolphins chief executive Tom Garfinkel “the safest environment possible.”Of course, even that might not be enough. While much remains unknown about the novel coronavirus, one fact that is painfully clear is how easily it spreads. No league or team wants their games to become 2630

"He's an amazing baby, all he does is eat and sleep," she says.But what makes this feat even more remarkable is that Emerson underwent a heart transplant in 2014. She was diagnosed with restrictive cardiomyopathy in 2011, and was later put on a long list of recipients for a heart transplant.Her prayers were answered on Valentine's Day in 2014. She received her heart from 21-year-old Blake Adkins, who died from a brain aneurysm. Emerson remains close to Adkins' mother Donna, who is overjoyed that her son lives on through Emerson and now her new baby boy, too."She was so excited because her son was not only able to keep me alive, but he was also to keep my baby alive as well," Emerson said. "I mean my heart, his heart, beats for two."Emerson says her family is now complete. She married her husband Bradley a year ago, and her family grew with his two children. Emerson also has an adopted son. Now with her new baby, Collings, she feels like her family is complete. But she knows it's a family that almost never was, and wouldn't have been without Adkins' sacrifice.She urges everyone to register to be a donor. She says she and her baby are proof it saves lives.This story was originally published by 1213
