James' World 2

A few days ago, my 4-year-old lifted up her shirt, pointed to her belly, and said, “Mommy, why is my tummy so big?” My heart skipped a beat, and I thought, This can’t be happening already. A moment later it occurred to me that she was probably (hopefully?) asking an innocent question about why the size of her stomach changes throughout the day, but I was nevertheless mortified. Recently my daughter has been asking me more and more whether she’s pretty and if she looks like a princess. She’s clearly getting the message from our society that looks and body size matter—even at the age of 4.

She’s not alone. Research suggests that preschool- and elementary-age children are more dissatisfied with their bodies now than ever before, that girls as young as 3 already perceive heaviness as “bad” and thinness as “good,” and that more than one-third of 5-year-old girls restrict their eating in order to stay thin.

If the pressure to be thin doesn’t seem like a big deal in itself, consider that kids who are dissatisfied with their bodies are more likely than others to become depressed and develop eating disorders or other dangerous habits. We constantly discuss the need to tackle the crisis of childhood obesity, and rightfully so—but we need to remember that more kids today have eating disorders than Type 2 diabetes. Nearly 1 in 3 high school girls, and nearly 1 in 6 high school boys, have disordered eating patterns serious enough to warrant medical help; one study found that 1 in 8 girls have made herself vomit at least once in the past three months.

Every day we are expected to make hundreds of decisions and judgements.

These range from small ones, like what to have for breakfast, to big ones like whether to take a new job.

The trouble is that our mental resources are limited – the human mind can only cope with so many things.

Given this huge challenge, we adopt mental shortcuts to function effectively. It is an approach which gets us through life, but which can also limit our growth as people.

Something as simple as thinking about the people we have around us can do a lot to change that and can even help us become more creative.

Astronomers working with the European Southern Observatory’s (ESO) Very Large Telescope say there are two supermassive black holes that are likely to merge into one “monster” black hole—and not far from Earth.

These black holes were observed in NGC 7727, a galaxy just 89 million light-years from the Milky Way. (Remember that the Alpha Centauri system is just four light-years away, so 89 million light-years is only close in a relative sort of way for space.) They’re disparate in size and very huge at 154 million and 6.3 million times the size of the sun.

The ESO is headquartered in Germany and represents dozens of European nations, but its telescopes are in the Southern Hemisphere, all in northern Chile. The Very Large Telescope (yes, that’s its real name) is specifically based in Paranal, Chile. Researchers from all over the world are able to collaborate on data gathered through the Very Large Telescope, but they’re even more excited for the opening of the Extremely Large Telescope by 2030.

For this new research, upcoming in the journal Astronomy & Astrophysics, the Very Large Telescope got an assist from other entities in nearby space. The two black holes are at the center of their galaxy, and because they’re so relatively close to Earth, lead author Karina Voggel (an astronomer at the Strasbourg Observatory in France) and her team were able to measure the black holes’ effects on the surrounding stars. Then, they used that data to extrapolate the existence of the two black holes.

Moving about isn’t meant to hurt. If you have normal range of motion, you should be able to stand, squat, walk, bend down, and reach over your head without any real effort or pain—and without having to warm up.

I’ve been working hard on moving better. I’ve gone from having shin splints and sore ankles when I run to bashing out 10Ks happy as anything. It takes a bit of work, but there’s a lot you can do to improve. And it doesn’t matter where you’re starting out, either.

“The body is robust, tolerant, and antifragile,” explains Kelly Starrett, a doctor of physical therapy and co-author of best-selling movement book, Becoming a Supple Leopard. “The resting state of the human being is pain-free.”

Unfortunately, the body has a use-it-or-lose-it policy. If you spend hours sitting at work each day, your hip flexors, hamstrings, and even the joints themselves will stiffen, potentially leading to back or knee pain, and trouble walking. If you don’t ever squat down on your haunches, your body will gradually lose the ability to do so. And too much typing or other computer use can impact your entire upper body.

Marine ecologist Piper Wallingford was doing fieldwork on the rocky shore of Laguna Beach, California, in 2016 when she noticed a dime-sized creature she’d never seen before. It was a dark unicorn snail, a predator that drills into mussels and injects an enzyme that liquefies their flesh. “Then,” Wallingford explains, “they basically suck it out like soup.”

The animal is native to the Mexican state of Baja California, Wallingford later learned, and it’s been migrating up the coast over the last few decades in search of new habitat, eating into local mussel populations along the way. It’s also one of countless species around the world — from white-tailed deer to lobsters to armadillos to maple trees — that are moving with the climate.

Ecologists expect climate change to create mass alterations in the habitats of these “range-shifting” or “climate-tracking” species, as they’re sometimes called, which will reshuffle ecosystems in ways that are hard to predict. The migrations are critical to species’ ability to survive hotter temperatures.

There are seasons in life when a 15-minute walk is the most you can commit to your exercise routine—and, hey, that’s 100 percent okay. Maybe your job is more of a nine to nine than a nine to five right now, or childcare is monopolizing your free moments. Whatever the case, we asked a cardiologist to answer the age-old question is walking enough exercise? And the first thing you need to know is that the simple answer is yes.

.

According to Michael Weinrauch, MD, a New Jersey-based cardiologist, the bottom line is that even the smallest neighborhood loop can have an immense impact on your health and well-being. “The take-home point here is that even 15 minutes a day of walking, without stopping, provides benefit with regards to cardiovascular morbidity and mortality,” he says. Morbidity refers to illness or disease, while mortality refers to death. Research has associated 15 minutes of activity with a 22 percent lower risk of death (mortality), and walking with a 43 percent reduced risk in stroke and reduction the risk factors of heart attack (morbidity), regardless of how fast your heart is beating. “Keep in mind, most of the research that has been done on the benefits of walking have been done without monitoring heart rates during physical activity. Remember, the Fitbit and smartwatch apps are still actually a relatively new phenomenon,” adds Dr. Weinrauch. Long story, short: The morbidity and mortality benefits of walking seem to occur regardless of your heart’s beats per minute (BPMs).

Active people tend to overthink what food is doing for their body—Is keto good for endurance? What’s the perfect post-training macro spread? Butter or no butter in my coffee?—but underthink what it’s doing for their mind. Yet you’ve probably noticed that what you eat impacts what’s going on upstairs. We’ve all devoured a cheat meal and afterward felt off, not just physically but also mentally and emotionally. And new research suggests that the connection between diet and mental well-being is a little more nuanced than scientists once thought.

Earlier studies suggest what you might expect: eating junk isn’t great for your brain. People who consume plenty of fruit, vegetables, and fish seem to be less at risk of depression compared to those who favor fatty meats, processed carbs, and sweets. But emerging research shows that even among healthy diets, some might be better for mental health than others. In a recent review published in Molecular Psychology, researchers analyzed 41 studies that sought to quantify the impact of various diets on clinical depression. The analysis accounted for a variety of eating plans including the Mediterranean diet, the DASH diet, and the Healthy Eating Index.
