☆ These are the battles worth fighting with kids about their phones
▼ + stars: | 2024-09-18 | by ( Kara Alaimo | ) edition.cnn.com time to read: +7 min

Follow her on Instagram, Facebook and X.CNN —It’s a familiar struggle in many households: trying to pry kids’ phones away before bedtime. But the research indicates that kids using their phones once they are under the covers is a bad idea. Using phones in interactive ways under the covers — for things such as gaming and multitasking — was worse for kids’ sleep than using it more passively, for things such as watching movies. Instead, parents might consider taking kids’ phones away before bed and returning them in the morning. This new research is a reminder that there are commonsense ways to help kids avoid the major dangers of using their phones.

☆ Ancient DNA adds to evidence debunking theory of Easter Island collapse
▼ + stars: | 2024-09-14 | by ( Katie Hunt | ) edition.cnn.com time to read: +6 min

CNN —Rapa Nui, also known as Easter Island, never experienced a ruinous population collapse, according to an analysis of ancient DNA from 15 former inhabitants of the remote island in the Pacific Ocean. Settled by Polynesian seafarers 800 years ago, Rapa Nui, today part of Chile, has hundreds of monumental stone heads that echo of the past. But that theory remains contentious, and other archaeological evidence suggests that Rapa Nui was home to a small but sustainable society. Easter Island genomesTo investigate Rapa Nui’s history further, researchers sequenced the genomes of 15 former residents who lived on the island during the past 400 years. But the ancient genomes add to a growing body of evidence that the idea of a self-inflicted population collapse on Easter Island is a false narrative, said Matisoo-Smith, who wasn’t involved in the study.

☆ A new path to better sleep: Evening exercise breaks
▼ + stars: | 2024-08-23 | by ( Dana Santas | ) edition.cnn.com time to read: +9 min

Now, a small efficacy study published July 16 in the journal BMJ Open Sport & Exercise Medicine suggests a simple yet effective strategy to improve sleep duration: incorporating short resistance, or strength training, exercise breaks in the evening. The findings were compelling: The participants slept an average of 27.7 minutes longer when they took regular exercise breaks compared with when they sat uninterrupted. “Our research found that interrupting evening sitting time with short bursts of light intensity exercise improved sleep duration and did not disrupt sleep quality,” Gale added via email. “Adding quick, simple and light resistance exercise breaks to your evening routine could be a simple way to improve your sleep and health,” he said. Better sleep could be just a few short exercise breaks away.

But some strategies are proven to be more effective than others, when it comes to raising successful children. Here are five ways parents can help set their kids up for future success, according to psychologists and other parenting experts. But when it comes to raising a successful child, one is more important than the other, educational psychologist Michele Borba wrote for CNBC Make It in 2022. Give them autonomyThe ability to self-motivate is one of the two important traits that can help kids grow into successful adults, child psychologist Dr. Tovah Klein told Make It last year. Don't stress over perfectionWojcicki raised three successful children — a doctor and two high-profile CEOs — but she never demanded perfection from them.

Scientists extracted DNA from chewing gum used by teenagers almost 10,000 years ago. The gum provided clues into what the teenagers had eaten and their lifestyle. Stone Age teenagers' diets included hazelnuts, duck, deer, fox, and trout, the study said. AdvertisementDNA extracted from chewing gum used by teenagers almost 10,000 years ago has provided fascinating clues into their prehistoric diet.

☆ Scientists said the ozone hole was recovering. That good news was premature, one study claims
▼ + stars: | 2023-11-21 | by ( Angela Dewan | ) edition.cnn.com time to read: +4 min

But in a new study published Tuesday, some scientists claim it may not be recovering at all, and that the hole may even be expanding. In a paper, published by Nature Communications, they found that ozone levels have reduced by 26% since 2004 at the core of the hole in the Antarctic springtime. They used historical data to compare that behavior and changing ozone levels, and to measure signs of ozone recovery. “Altogether, our findings reveal the recent, large ozone holes may not be caused just by CFCs,” Kessenich said. “Those events have been shown to have strongly decreased the ozone hole size,” he said, “so including those events would probably have nullified any long-term negative trend.”

☆ This Extinct Dolphin Had Tusks That Fish Were Wise to Avoid

The waters off New Zealand 25 million years ago were home to early baleen whales, megatooth sharks and human-size penguins. Now researchers are adding a bizarre dolphin to the mix that may have used tusklike teeth to thrash prey into submission. “Mentally, I just couldn’t figure out what could possibly need teeth like that,” Dr. Coste said. In a paper published Wednesday in the journal Proceedings of the Royal Society B, Dr. Coste and her colleagues described the snaggletoothed dolphin as a unique species, Nihohae matakoi. The curious cetacean’s genus, Nihohae, is a combination of the Maori words for “teeth” and “slashing.”

☆ The Great Pacific Garbage Patch is actually a unique ocean ecosystem teeming with sea creatures that cling to the plastic trash
▼ + stars: | 2023-04-18 | by ( Kelsey Vlamis | ) www.businessinsider.com time to read: +3 min

The Great Pacific Ocean Patch refers to a big swirling soup of plastic in the ocean. The findings challenged the assumption that coastal species couldn't survive in the open ocean. The Great Pacific Garbage Patch typically refers to an area of the Pacific Ocean between California and Hawaii in which floating trash concentrates due to factors like wind and currents. The findings also contradicted the assumption that coastal species could not survive in areas of open ocean. The Great Pacific Garbage Patch refers to areas of marine debris concentration in the North Pacific Ocean.

If doctors believe that the death was caused solely by COVID-19 pneumonia, they must report to their superiors, who will arrange for two levels of "expert consultations" before a COVID death is confirmed, it said. "We have stopped classifying COVID deaths since the reopening in December," said a doctor at a large public hospital in Shanghai. Three other doctors at public hospitals in different cities said they were unaware of any such guidance. Before Saturday, China was reporting five or fewer COVID deaths per day. But the hospital told him it had run out of medicine, so they could only go home.
