Wreckage from the USS Lexington -- a US aircraft carrier sunk by the Japanese during World War II -- has been discovered 500 miles off the Australian coast by a team of explorers led by billionaire Paul Allen, the Microsoft co-founder announced on Monday.One of the first US aircraft carriers ever built, the vessel dubbed "Lady Lex" was located at the bottom of the Coral Sea -- nearly two miles below the surface -- by the expedition crew of Research Vessel Petrel on Sunday, Allen said.The Lexington was lost in May 1942 along with 216 of its crew and 35 aircraft during what is considered the first carrier battle in history -- the Battle of the Coral Sea."To pay tribute to the USS Lexington and the brave men that served on her is an honor," Allen said in a statement. "As Americans, all of us owe a debt of gratitude to everyone who served and who continue to serve our country for their courage, persistence and sacrifice."Along with the USS Yorktown, the Lexington and its fleet faced off against three Japanese aircraft carriers and is credited with helping to stop Japan's advances on New Guinea and Australia.The battle occurred just one month before the US Navy "surprised Japanese forces at the Battle of Midway and turned the tide of the war in the Pacific for good," according to Allen."The Battle of the Coral Sea was notable not only for stopping a Japanese advance but because it was the first naval engagement in history where opposing ships never came within sight of each other," read the statement from Allen.US ships were able to rescue more than 2,000 sailors before the Lexington ultimately sank from the damage sustained from a bombardment of Japanese torpedoes."As the son of a survivor of the USS Lexington, I offer my congratulations to Paul Allen and the expedition crew of Research Vessel (R/V) Petrel for locating the "Lady Lex," sunk nearly 76 years ago at the Battle of Coral Sea," Navy Adm. Harry B. Harris of US Pacific Command said Monday in a statement."We honor the valor and sacrifice of the 'Lady Lex's' sailors -- all those Americans who fought in World War II -- by continuing to secure the freedoms they won for all of us," he said. 2190

-- 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
