-- 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

has been arrested, as deputies say she used a credit card in her boyfriend's name to get back at him for not buying her a plane ticket to New York.Serina Wolfe, 24, of Buffalo, N.Y., was in the news a few days ago when she left a ,000 tip for a server grieving the loss of her dog, but now we have the rest of the story.According to an arrest affidavit, Wolfe made a purchase using a credit card in her boyfriend's name. He said they were in an argument because he wouldn't buy her a plane ticket home to New York.Wolfe denied making the purchase. Then her boyfriend reported the charge to his credit card company as fraudulent, saying he believes she was drunk or trying to get back at him.Clear Sky Cafe, where the tip was given, was notified the purchase was fraudulent on Monday, and they had already paid out their waitress for the amount of ,000 for the tip and .37 for the food.Wolfe voluntarily handed over the card she used to deputies and was arrested for grand theft.It is unclear at this time whether or not the server will get to keep the money. 1067

-- made the initial call to 911 Friday about 10 a.m. ET. A second call came from another person at the scene who reported a medical emergency involving a large bird, said Lt. Joshua Crews of the Alachua County Sheriff's Office.Hajos was transported to a nearby hospital, where he died, the lieutenant said. The cassowary remains on Hajos' property as authorities conduct an investigation into the attack, he said.The owner was a breeder of the rare bird that is native to Australia and New Guinea, Alachua County Deputy Fire Chief Jeff Taylor said.The death was an accident, officials said. It appears the man fell, and the cassowary attacked him after the fall, Taylor said.The Florida Fish and Wildlife Conservation Commission considers cassowaries Class II wildlife, meaning they pose a danger to humans and are subject to specific cage requirements. Owners must also have 877
