Watching Cartoons Has Helped Me Manage My Mental Illness

 

More than six years ago, I was diagnosed with generalized anxiety disorder and depression. The traditional approaches ― exercise, journaling and breathing skills ― have helped, as has medication. And I watch cartoons.

 

Yes, this year I discovered a surprising degree of comfort in a 12-year-old boy named Steven Universe.

Why Do Men Run Faster Than Women?

sRunning is a sport that both men and women enjoy, whether they’re racing in a 5K or a marathon, or competing for a team or their country while speeding around a track. But no matter the venue, it’s pretty common to see men clock faster times than women do.

Given that both men and women train equally hard, why is it that men, on average, are faster runners than women? Even the world’s fastest man is about a second speedier on the 100-meter dash than the world’s fastest woman: Usain Bolt did it in 9.58 seconds, versus the late Florence Griffith Joyner’s time of 10.49 seconds.

Sea creatures’ sticky ‘mucus houses’ catch ocean carbon really fast

 

050317_SM_mucous-house_main_FREE.jpgNever underestimate the value of a disposable mucus house.

Filmy, see-through envelopes of mucus, called “houses,” get discarded daily by the largest of the sea creatures that exude them. The old houses, often more than a meter across, sink toward the ocean bottom carrying with them plankton and other biological tidbits snagged in their goo.

Now, scientists have finally caught the biggest of these soft and fragile houses in action, filtering particles out of seawater for the animal to eat. The observations, courtesy of a new deepwater laser-and-camera system, could start to clarify a missing piece of biological roles in sequestering carbon in the deep ocean, researchers say May 3 in Science Advances.

MARS MAY NOT HAVE BEEN BORN ALONGSIDE THE OTHER ROCKY PLANETS

Mars

Mars may have had a far-out birthplace.

Simulating the assembly of the solar system around 4.56 billion years ago, researchers propose that the Red Planet didn’t form in the inner solar system alongside the other terrestrial planets as previously thought. Mars instead may have formed around where the asteroid belt is now and migrated inward to its present-day orbit, the scientists report in the June 15 Earth and Planetary Science Letters. The proposal better explains why Mars has such a different chemical composition than Earth, says Stephen Mojzsis, a study coauthor and geologist at the University of Colorado Boulder.

How Would Just 2 Degrees of Warming Change the Planet?

umThe Earth is home to a range of climates, from the scorching dunes of the Sahara to the freezing ridges of Antarctica. Given this diversity, why are climate scientists so alarmed about a worldwide temperature increase of just 2.7 degrees Fahrenheit (1.5 degrees Celsius)?

Changing the average temperature of an entire planet, even if it’s just by a few degrees, is a big deal, said Peter deMenocal, a paleoclimate scientist at Lamont-Doherty Earth Observatory at Columbia University in New York.

“A person living in any one location can experience huge changes in weather and even in climate, but those are often compensated by changes on opposite sides of the world,” deMenocal told Live Science.

More Brain Differences Seen Between Girls, Boys With ADHD

Proposed_Symptoms_of_ADHD

Girls and boys with attention-deficit/hyperactivity disorder don’t just behave differently. Parts of their brains look different, too. Now, researchers can add the cerebellum to that mismatch.

For boys, symptoms of the disorder tend to include poor impulse control and disruptive behavior. Girls are more likely to have difficulty staying focused on one task. Studies show that those behavioral differences are reflected in brain structure.  Boys with ADHD, for example, are more likely than girls to display abnormalities in premotor and primary motor circuits, pediatric neurologist Stewart Mostofsky of Kennedy Krieger Institute in Baltimore has reported previously.

Now, Mostofsky and colleagues have looked at the cerebellum, which plays a role in coordinating movement. He reported the new findings March 25 at the Cognitive Neuroscience Society’s annual meeting in San Francisco.

Girls ages 8 to 12 with ADHD showed differences in the volume of various regions of their cerebellum compared with girls without the condition, MRI scans revealed. A similar comparison of boys showed abnormalities, too. But those differences didn’t match what’s seen between girls, preliminary analyses suggest. So far, researchers have looked at 18 subjects in each of the four groups, but plan to quintuple that number in the coming months.

Differences seem most prominent in areas of the cerebellum that control higher-order motor functions, Mostofsky said. Those circuits help regulate attention and plan out behavior, versus directing basics like hand-eye coordination. That could help explain why ADHD affects girls’ behavior differently than boys’.

JUMPING GENES PLAY A BIG ROLE IN WHAT MAKES US HUMAN

chimpanzee and human

THE DIFFERENCE  Humans and chimpanzees are easy to tell apart, even though they share a primate ancestor. Jumping genes helped sculpt their distinctions

Face-to-face, a human and a chimpanzee are easy to tell apart. The two species share a common primate ancestor, but over millions of years, their characteristics have morphed into easily distinguishable features. Chimps developed prominent brow ridges, flat noses, low-crowned heads and protruding muzzles. Human noses jut from relatively flat faces under high-domed crowns.

Immune Cells Play Surprising Role In Steady Heartbeat

macrophages and heart cells

Immune system cells may help your heart keep the beat. These cells, called macrophages, usually protect the body from invading pathogens. But a new study published April 20 in Cell shows that in mice, the immune cells help electricity flow between muscle cells to keep the organ pumping.

Macrophages squeeze in between heart muscle cells, called cardiomyocytes. These muscle cells rhythmically contract in response to electrical signals, pumping blood through the heart. By “plugging in” to the cardiomyocytes, macrophages help the heart cells receive the signals and stay on beat.
