has been born in Baltimore.The Maryland Zoo says the girl was born on Sunday, December 29, 2019, to 24-year-old chimpanzee Raven.“The baby is gripping well and is very vocal,” said Erin Cantwell, mammal collection and conservation manager. “Similar to many new moms, Raven needs a lot of support and encouragement. She’s a first-time mom, and we are using behavior training to guide her on how to carry and nurse the baby properly.”Raven was pregnant for about eight months. Raven is the second chimpanzee to give birth at the Zoo recently. In July 2019, the zoo welcomed baby Lola.Experts say developmental milestones for chimpanzees are similar to those for human babies. The staff will monitor the baby for important abilities, such as the ability to hold her head up on her own, use of her fingers and toes to grasp things, learning vocalizations and facial expressions, and teething.There are currently 14 endangered chimpanzees among the Maryland Zoo’s troop including the newborn. 989

But there is one thing she loves even more."Patrick Mahomes," Reese said.While she roots for her favorite quarterback, her mom said she is always begging to watch makeup videos or even do her makeup."She was watching me do my makeup. She has done that for years. She is an observant, curious kid," said Nicole Wallace, Reese's mom.Last Friday, while all the kids were home from school because of the ice storm, the mother-daughter duo wanted to make a video for the upcoming game."We have this whole day. Let's do a tutorial in honor of our team and our favorite player, Patrick Mahomes," Wallace said.While Mahomes doesn't wear makeup, he is known for his hair and headbands.Wallace posted the video of Reese on 715

-- 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

YouTube Kids has struggled with disturbing videos, like beloved Disney characters in violent or sexual situations, sneaking past its automated filters.Now the app is adding new settings to give parents more control over what videos their kids can see.The company announced Wednesday an option to filter videos by "approved content only," so parents can whitelist channels and subjects.The effort comes four months after reports called attention to troves of videos with inappropriate themes on the video-sharing site's kid-friendly platform. Content for YouTube Kids is selected from the main YouTube app and screened using machine learning algorithms. But some videos, such as cartoons disguised as age appropriate, slip through the cracks.Once the new setting is turned on, users can pick collections from trusted creators such as PBS and Kidz Bop, or themed collections curated by YouTube Kids itself.YouTube is launching another tool later this year that will let parents choose every video or channel their kid can see in the app."While no system is perfect, we continue to fine-tune, rigorously test and improve our filters for this more open version of our app. And, as always, we encourage parents to block and flag videos for review that they don't think should be in the YouTube Kids app," the company said in a blog post announcing the new features.It's the kind of control parents have been asking for from the popular app, but it also puts the onus on them to filter content. It's a side effect of the way YouTube Kids finds its videos.When a video for children is uploaded to the main YouTube platform, it is not automatically added to the YouTube Kids library. The videos are reviewed by machine learning algorithms to determine whether or not they are appropriate for the app.The automated process -- one YouTube calls very thorough -- can take days. A human doesn't check the videos before they're added, but parents can flag videos they find alarming later and a content reviewer will check it out.However, it's unlikely parents are constantly watching YouTube Kids videos along with their children. It's possible this safety guard isn't sufficient for catching every odd video your kid might see.The flag-the-video-later system has created some problems for the service. Some YouTube creators have uploaded concerning videos marked as kids content that slips past the screening process. These videos have included Spiderman urinating on Frozen's Elsa, Peppa Pig drinking bleach, and Micky Mouse getting run over by a car.The company continues to change its rules to crack down on the issue, but creators are constantly looking for ways to trick the system.YouTube Kids still has its main library available by default for now, and the company says it is working on more controls for parents. 2837
