Flooding May Have Contributed to Cahokia’s Decline

Archaeology Magazine

MADISON, WISCONSIN—Sediment cores from Horseshoe Lake, located in the Mississippi floodplain near the center of Cahokia, and Grassy Lake, roughly 120 miles downstream, provide clues to the rise and fall of the ancient city, according to geographers Samuel Munoz and Jack Williams of the University of Wisconsin, Madison.

Researchers: Major floods coincided with desertion of Cahokia Mounds

St. Louis Public Radio

The people who built and lived among the tall, sculpted mounds now preserved at Cahokia Mounds Historic Site have long presented a mystery to archeologists.One of the biggest mysteries: Why did they leave? A team of UW-Madison geographers studying pollen deposits buried in the sediment under Horseshoe Lake may have stumbled upon new evidence that helps explain Cahokia’s decline.

Floods might have doomed prehistoric American city

Nature

Cahokia was a pretty big deal in the 1100s. Founded by a complex cultural group that built tall mounds and sweeping plazas, the city near present-day St Louis, Missouri, was home to tens of thousands of people. But its population began declining around 1200, and by 1350, Cahokia was a ghost town.

What your smile says about where you’re from

If you come from a country of immigrants, you’re more likely to crack a friendly smile on the street. That’s the conclusion of a new study, which may explain why Americans beam more than their Chinese and Russian counterparts. Scientists have known for decades that societies have their own unwritten rules about when it’s appropriate to smile, frown, or get angry. These rules are part of a country’s “emotion culture,” the norms that influence how and when people express whether they’re pleased or upset. Researchers often study these differences geographically, finding that the United States and the West tend to be more expressive than China and the East. But those geographical studies overlook the important role migration played in shaping emotion culture, says Paula Niedenthal, a psychologist at the University of Wisconsin, Madison.

Ancient Native American city may have been done in by Mississippi floods

Ars Technica

Long before Europeans arrived to settle St. Louis, an impressive human construction stood on the eastern side of the Mississippi River. It was the Native American city of Cahokia. At its height, tens of thousands lived in and around Cahokia, leaving behind great earthen mounds as testament. The largest still stands about a hundred feet tall today, minus what was likely a temple that once adorned its crest.

Why Well-Being Is a Skill That Can Be Learned

Huffington Post

“I kept doing the body scan to feel calm,” a fifth grade student explained to my colleagues as he recollected coping with a stressful situation at home. A “body scan” involves checking in with your body and noticing how it feels in the present moment. There’s no action required other than observing experiences as they unfold.

As a neuroscientist applying the insights of my center’s research to the real world, including in classrooms, I hear similar stories from people of all ages expressing a desire to calm their minds, to take baby steps to reduce negative emotions, improve well-being and respond with resilience to factors outside of our control.

Turning prairies into gas: study finds U.S. biofuel production has big impacts on grasslands

Corn and soybean cultivation soared in the late 2000s, as U.S. agribusiness rushed to respond to federal legislation rewarding biofuels production. Debate since the institution of the program has centered on the question of whether biofuel crop expansions have come at the expense of plowed-under biodiverse grasslands and prairie ecosystems. A new study largely settles that argument.
