Most Teens Take a Voluntary Week-Long Break From Social Media

by Barbara Ortutay

 

The common stereotype has teens glued to their phones 24-7. But nearly 60 percent of teens in the U.S. have actually taken a break from social media — the bulk of them voluntarily, a new survey found. The poll, from The Associated Press-NORC Center for Public Affairs Research, surveyed teens aged 13 to 17 and found that most value the feeling of connection with friends and family that social media provides. A much smaller number associate it with negative emotions, such as being overwhelmed or needing to always show their best selves. The survey, released Thursday, found that teens' social media breaks are typically a week or longer, and that boys are more likely to take longer breaks.

Surgeons Conduct Head Transplants on Rats, Say Humans Are Next

After 14 head transplants on rats, a pair of surgeons say they will attempt a human head transplant in the next 10 months in China.

by Eva Hershaw

 

Chinese scientists have transplanted the head of a donor rat onto the back of a host body, creating an equally garish and impressive two-headed rat that may offer insights into the viability of an eventual human head transplant.

 

The process, which was done by way of a rat triad, which included a donor, recipient, and blood supply rat, provided a continuous blood supply to the donor brain throughout the transplant, avoiding brain tissue hypothermia — a condition where the brain suffers in absence of a blood supply. The problem has long been one of the major barriers to carrying out a successful head transplant in animal specimens.

Rare ‘Coffin Birth' Found in Black Death Burial Site

by Rossella Lorenzi

 

Researchers investigating a 14th century burial ground have identified a rare case of "coffin birth" - a gruesome phenomenon in which a deceased pregnant woman's fetus is expelled within the grave. The event, which has seldom been reported in archaeology, is known as postmortem fetal extrusion. It results from a build-up of gas pressure within the decomposing body. "In this case, we have a partial expulsion of a 38- to 40-week-old fetus, which was found to be complete and to lie within the birth canal," Deneb Cesana, at the University of Genova, told Seeker.

SpaceX successfully launches secret government spy satellite

First stage of Falcon 9 rocket lands back at Cape Canaveral

 

SpaceX launched a top-secret spy satellite for the U.S. government Monday morning and then successfully landed the booster for recycling. The unmanned Falcon 9 rocket lifted off from its NASA-leased pad at Kennedy Space Center in Florida. It was SpaceX's first mission for the National Reconnaissance Office. No details were divulged about the newly launched NRO satellite. Instead, SpaceX focused its webcast on the successful touchdown of the first-stage booster. The leftover booster — its job done — landed at Cape Canaveral Air Force Station several minutes after liftoff. Sonic booms rattled the area, serving as a Monday morning wake-up call. Across the country, cheers erupted at SpaceX Mission Control at company headquarters in Hawthorne, California. SpaceX strives to return most of its boosters for reuse.

 

The company's first recycled rocket flew last month. This was the fourth SpaceX booster landing at Cape Canaveral; even more have landed on ocean platforms.

Weight loss and water consumption appear to be linked

 

Mandy Oaklander
July 12, 2016

 

    The average American doesn’t drink nearly enough water – only 4 cups a day, by some estimates. At the same time, high obesity rates here have barely budged, despite a continued focus on diet and physical activity.

    Some researchers don’t think that’s a coincidence. “There’s so much focus on food and exercise, but so much more than just food and exercise goes into weight,” says Dr. Tammy Chang, assistant professor in the department of family medicine at the University of Michigan medical school.

    Could the amount of water people drink have any link to their weight? In a new study published in the Annals of Family Medicine, Chang and her colleagues wanted to find out, so they used recent data from about 9,500 adults enrolled in the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of what Americans are eating. The data also included information about how hydrated they were, measured by the concentration of people’s urine.

    About 33% of the people in the study weren’t adequately hydrated. What’s more, the researchers found a link between dehydration and overweight. There may be all kinds of explanations for these findings. People with obesity need more water than people who have smaller bodies, making the hydration threshold potentially harder to reach. But some research suggests that water can play a role in weight control, showing that when overweight people drink water before a meal, they eat fewer calories than if they eat it without water.

    So how can you tell if you’re drinking enough water? Instead of sticking to a cup-per-day recommendation, Chang says the most reliable way to tell is to check the color of your urine. If it’s light, almost the color of water, then you likely are, but if it’s dark, you need to step up your water intake.

    Drinking plain water isn’t the only way to do that. Fresh fruits and vegetables are packed with water and have far more than processed foods. A cup of sliced radishes has half a cup of water, while a 2-cup serving of watermelon – not to mention a single cucumber – both have more than a cup of water. “They’re good for you because of their nutritional value, but you’re improving your hydration as well,” Chang says.
