The making of Stonehenge; behind heat deaths
 | | LIVING ART ENTERPRISES, LLC/SCIENCE SOURCE | | Small brains. Underdeveloped neural connections. Communication and memory issues, delays in processing information, and difficulties in dealing with frustration.
Researchers are learning more about the effects on kids born to mothers who drink during pregnancy. Up to 1 in 20 kids may have fetal alcohol spectrum disorders, experts estimate, and specialized treatment is spotty for them and their parents and siblings. Specific treatment has made strides in boosting math skills, executive function, and decision-making, Nat Geo reports. (Pictured above, a healthy fetus shown in an ultrasound.)
“This is such a prevalent issue without any supports and without [enough] awareness,” says Joel Sheagren, who with his wife, adopted two children with prenatal alcohol exposure. A proposal in Congress seeks to provide resources at the national level for screening, research, and other support.

 | | JEFFREY R. WOZNIAK | | A comparison of brains of 12-year-olds with (above left) and without fetal alcohol spectrum disorders (above right). In the top row, the left image shows an abnormal corpus callosum (bright white matter fiber band), while the right image is typical. On the bottom row, the left image shows underdevelopment in the white matter, or the brain’s “wiring.” On the bottom right is the typical development. Read more

 | | PHOTOGRAPH BY TOM CANNON | | Teaming up: Whale sharks might be known for chasing fish but they’re not the fastest swimmers. They get help from other animals, hunting in tandem with predators including tuna, other sharks, and diving seabirds. When faster predators force fish into a defense “bait ball,” sharks swoop in (pictured above), Sarah Keartes reports.

| Where polar bears are your neighbors: Electrician Ida Kristoffersen expected to work a year in an Arctic scientific settlement in Norway, but she’s stayed nearly two years and doesn’t want to leave anytime soon. Photographer Esther Horvath, who specializes in the world’s frigid poles, explored life in the year-round settlement in Svalbard—and found part of it fun. She found the same thing at a Danish scientific outpost in Greenland.

| | A dolphin in the sky: With the moon rising well after midnight, the next few nights are ideal to check out the tiny but easily recognizable constellation Delphinus, the dolphin swimming through the waves of the Milky Way. Its four brightest stars form a curved, diamond asterism known as Job’s Coffin. The nose of the dolphin is marked by Gamma Delphini, a beautiful contrasting double star that is easily split with a small telescope. In the meantime, looking for wild images from NASA’s newest space telescope? Check these out.

 | | One in four people in the U.S. live with some form of disability, and many are invisible or dynamic, like me. By speaking up about 'all' of who I am, becoming more visible in the community, and sharing my story, I hope to inspire others to persevere through adversity. | | | Jennifer W. Lopez

 | | PHOTOGRAPH BY LIBRARY BOOK COLLECTION/ALAMY | | The father of genetics: Students of science learn how the pioneering pea experiments of Gregor Mendel (shown above in 1866) led to the advent of DNA splicing and CRISPR. Featured in an exclusive report by Nat Geo’s Czech edition, the science came full circle recently when his body was exhumed, and his DNA sequenced to learn more about his ancestry and health. Mendel, who was born 200 years ago today, wasn’t highly regarded in his lifetime, but following his death, new generations of biologists “realized he had actually been on to something,” Carl Zimmer wrote for Nat Geo in 2005.
