– One Pantry At a Time – to get grocery store gift cards to those students and their families in need. The concern: parents working hourly jobs that have been cut back – or laid off altogether – may be putting the ability of those families to get food at risk. “They're losing all of their money now,” Vena said. “They've got nothing coming in. So, for us, this was what do we need to do.” Partnering with the school principals in Arlington, the teachers are working on getting a 0 grocery store gift card into the hands of all 8,300 students who get free and reduced school meals. It’s not an official school district fundraiser – just something these teachers took it upon themselves to do. They document, via photograph, each time they meet with a school principal at the school, to hand them the gift cards for distribution. So far, they’ve raised nearly 0,000. “I think as soon as people saw that there was an opportunity to help those in need, they jumped on it,” Springberg said. “And I know that there are communities all over the country with like-minded people, who really just need some direction and to know how they can easily help the less fortunate.” It’s an idea they hope spreads beyond their community.

-- 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

between cyclists and moped riders broke the stillness in an otherwise peaceful park on Saturday.Eyewitness video shows the fight began in Denver's Cheesman park over an apparent dispute over stop sign right-of-way.Emotions escalated seconds later, and in the video, and the cyclists and mopeders pushed, yelled and threw punches.People who regularly visit the park say they were shocked to see what had happened, while others say similar incidents have occurred throughout the city.Denver police say both bicycles and mopeds have to follow the same rules as cars and stop and stop signs unless they're inside a protected green lane.The right of way then belongs to whoever arrives at the stop sign first.Police say they are looking into the incident.This story was originally published by Ivan Rodriguez on 809

You’ve probably noticed new electronic payment screens when purchasing coffee or other items at a counter. With the new systems, do customers end up tipping more?  An automatic tipping system called Toast says since 2017, quick service restaurants using their system have received tips on nearly 60 percent of credit card orders, compared to 28 percent previously.    "The basic idea is to make it very easy for you, very convenient for you, and create an expectation that this is a norm,” says Dr. Kevin Masters, a professor at CU Denver. “And this is what’s usually done."   Dr. Masters says the psychology behind the process is to cause stress for customers, which makes them tip no matter how much they decide.   "These ones where you are at a coffee shop or taxi places like that, you're given this automatic tip, especially if there is a line behind you there is a pressure," he says.   If you think you're the only one who feels awkward in this situation, you're not alone. Nathan, who works as a barista, says the feeling is mutual. But he does believe he gets tipped more with automatic tipping screens.    Dr. Master's says whether or not you tip, it's all psychological with the pressure you feel."Most of us, I think, would rather just get it over with,” he says. “So, if it costs me a few more cents on this cup of coffee, [no] big deal."    1427
