With cell phones, tablets, and laptops, children have more ways than ever to immerse themselves in the digital world. But as a new study finds, too much time spent in front of a screen could have consequences for a child’s intellectual development, Science News reports.

For a paper published in Lancet Child & Adolescent Health, researchers extracted data from the 10-year, longitudinal Adolescent Brain Cognitive Development study. They focused on the daily activities of 4524 American children, aged 8 to 11, that took place between September 1, 2016 and September 15, 2017. The team analyzed how well the respondents adhered to recommended guidelines for physical activity, recreational screen time, and sleep duration.

Researchers found that kids who spent more than two hours in front of a screen each day performed worse on memory, language, and other brain activity tests than kids who came in under that threshold. The participants averaged 3.6 hours a day interacting with screens. Subjects that fell under the two-hour mark recorded 4 percent higher scores on thinking tests than kids who spent more time on devices.

The result was part of a larger effort looking at the potential effects of adhering to Canadian 24-Hour Movement Guidelines for Children and Youth, which recommends an hour of exercise daily, less than two hours of screen time, and nine to 11 hours of sleep for children aged 5 to 13. Just 5 percent of subjects met all three recommendations, while 71 percent met at least one recommendation. The findings indicates that lack of sleep, too little physical activity, and idling in front of screens may be too common for children's wellbeing.

Researchers cautioned that the study shows data for only a specific time frame, and it does not demonstrate a causative relationship between screen time and poor cognition (it’s possible that smarter kids elect to spend less time on devices). Nor did the study examine whether watching or interacting with educational content made a difference over entertainment content. It does, however, provide some compelling data that kids might benefit from spending less time streaming and more time moving.

Keep Your Cat Busy With a Board Game That Doubles as a Scratch Pad

No matter how much you love playing with your cat, waving a feather toy in front of its face can get monotonous after a while (for the both of you). To shake up playtime, the Cheerble three-in-one board game looks to provide your feline housemate with hours of hands-free entertainment.

Cheerble's board game, which is currently raising money on Kickstarter, is designed to keep even the most restless cats stimulated. The first component of the game is the electronic Cheerble ball, which rolls on its own when your cat touches it with their paw or nose—no remote control required. And on days when your cat is especially energetic, you can adjust the ball's settings to roll and bounce in a way that matches their stamina.

The Cheerble balls are meant to pair with the Cheerble game board, which consists of a box that has plenty of room for balls to roll around. The board is also covered on one side with a platform that has holes big enough for your cat to fit their paws through, so they can hunt the balls like a game of Whack-a-Mole. And if your cat ever loses interest in chasing the ball, the board also includes a built-in scratch pad and fluffy wand toy to slap around. A simplified version of the board game includes the scratch pad without the wand or hole maze, so you can tailor your purchase for your cat's interests.

You can back the Kickstarter today to claim a Cheerble product, with $32 getting you a ball and $58 getting you the board game. You can make your pledge here, with shipping estimated for July 2020.

A Prehistoric Great White Shark Nursery Has Been Discovered in Chile

Great white sharks (Carcharodon carcharias) may be one of the most formidable and frightening apex predators on the planet today, but life for them isn’t as easy as horror movies would suggest. Due to a slow growth rate and the fact that they produce few offspring, the species is listed as vulnerable to extinction.

There is a way these sharks ensure survival, and that is by creating nurseries—a designated place where great white shark babies (called pups) are protected from other predators. Now, researchers at the University of Vienna and colleagues have discovered these nurseries occurred in prehistoric times.

In a study published in the journal Scientific Reports, Jamie A. Villafaña from the university’s Institute of Palaeontology describes a fossilized nursery found in Coquimbo, Chile. Researchers were examining a collection of fossilized great white shark teeth between 5 and 2 million years old along the Pacific coast of Chile and Peru when they noticed a disproportionate number of young shark teeth in Coquimbo. There was also a total lack of sexually mature animals' teeth, which suggests the site was used primarily by pups and juveniles as a nursery.

Though modern great whites are known to guard their young in designated areas, the researchers say this is the first example of a paleo-nursery. Because the climate was much warmer when the paleo-nursery was in use, the researchers think these protective environments can deepen our understanding of how great white sharks can survive global warming trends.
