STEAM (36)
STEAM stands for Science, Technology, Engineering, Arts, and Mathematics. These are study subjects in which U.S. pupils are generally not at par with their peers in other developed countries. That reduces our chances of finding timely solutions to the dire crises that face our planet. It also diminishes the chances for the U.S. economy to remain competitive.
More people already know the STEM abbreviation. Some states and communities are now implementing STEM education programs. Many experts believe that Art education is important, too. Scientific studies have shown that STEM students and professionals who attended art classes are more likely to find crative solutions to new problems.

Smokies researchers make a formal acquaintance with a familiar salamander
Jonathan Cox
Great news from the Smokies via Instagram!
The “salamander capital of the world” just gained a new member! Meet our 31st species: the Cherokee black-bellied salamander, or Desmognathus gvnigeusgwotli. Its species name means “black belly” in the Cherokee language. Scientists used genetics to find out that it is different from the other black-bellied salamander in the park.
There’s a whole world in the dirt beneath your feet

Dirt is far from just dirt. It’s a foundation for life.
This story was originally published by The Revelator.
Look down. You may not see the soil beneath your feet as teeming with life, but it is.
Better scientific tools are helping us understand that dirt isn’t just dirt. Life in the soil includes microbes like bacteria and fungi; invertebrates such as earthworms and nematodes; plant roots; and even mammals like gophers and badgers who spend part of their time below ground.
It’s commonly said that a quarter of all the planet’s biodiversity lives in the soil, but that’s likely a vast understatement. Many species that reside there, particularly microorganisms such as viruses, bacteria, fungi and protists, aren’t yet known to science.

Discovery of ancient ambush predator is one of few large carnivores found at East Tennessee paleontological site
JOHNSON CITY — Overseen by the Don Sundquist Center of Excellence in Paleontology at East Tennessee State University, researchers have studied the Gray Fossil Site for over 20 years. They have identified many extinct animal and plant species of the Pliocene epoch that lived there some 5 million years ago. While large herbivores are well known from the site, large predators are relatively uncommon, so far including only alligators and scarce remains of at least one sabertooth cat.
Now, there’s a new predator on the scene.
A recent study published in the Journal of Paleontology describes a single right humerus (upper arm bone) of an animal named Borophagus, a member of an extinct group more commonly called bone-crushing dogs. The animal is so named for its powerful teeth and jaws. This is the first evidence of any animals in the dog family from the Gray Fossil Site.
The research was conducted by Emily Bōgner, a doctoral student at the University of California, Berkeley, and alumnus of ETSU’s paleontology master’s program, and Dr. Joshua Samuels, associate professor in the ETSU Department of Geosciences and curator at the Gray Fossil Site and Museum.
An under-appreciated Black scientist pioneered the modern study of bees and other insects
Written by Edward D. MelilloZoologist Charles Henry Turner was the first scientist to prove certain insects could remember, learn and feel. Charles I. Abramson via The Conversation
Charles Henry Turner concluded that bees can perceive time and develop new feeding habits in response
This story was originally published by The Conversation. Edward D. Melillo is a professor of history and environmental studies at Amherst College.
On a crisp autumn morning in 1908, an elegantly dressed African American man strode back and forth among the pin oaks, magnolias and silver maples of O’Fallon Park in St. Louis, Missouri. After placing a dozen dishes filled with strawberry jam atop several picnic tables, biologist Charles Henry Turner retreated to a nearby bench, notebook and pencil at the ready.
Following a midmorning break for tea and toast (topped with strawberry jam, of course), Turner returned to his outdoor experiment. At noon and again at dusk, he placed jam-filled dishes on the park tables. As he discovered, honeybees (Apis mellifera) were reliable breakfast, lunch and dinner visitors to the sugary buffet. After a few days, Turner stopped offering jam at midday and sunset, and presented the treats only at dawn. Initially, the bees continued appearing at all three times. Soon, however, they changed their arrival patterns, visiting the picnic tables only in the mornings.
Tennessee Aquarium diversifies its scientific assets

Tennessee Aquarium fellowships bring minorities into the science space
CHATTANOOGA — Never let it be said that all summer jobs are created equal.
Squatting on his heels to dangle the flexible hose of an environmental DNA pump into a briskly flowing North Georgia stream, the last few weeks have been anything but ordinary for Spencer Trimpe. With the pump’s droning motor steadily collecting a sample of water to filter out genetic traces of the stream’s inhabitants, he doesn’t bother holding back a smile.
A lanky junior biology major from Thomas More University, Trimpe is one of two students selected as part of the Tennessee Aquarium’s George Benz Aquatic Ecology Fellowship. Instead of manning a cash register or waiting tables this summer, he’s assisting freshwater scientists from the Tennessee Aquarium Conservation Institute with a variety of research projects.
UTK has quite the collection of earthly remains
WBIR: UT got good bones
KNOXVILLE — The University of Tennessee boasts an incredible collection of animal skeletons — from hummingbirds to bison, according to a story from WBIR. It’s among the largest such assemblages in the country. (There are also skeletons at the Body Farm, but that’s a different story).
The skeletons are part of the UT Anthropology Department’s Vertebrate Osteology Collection.
“We have over 12,000 vertebrate specimens in our collections. So that’s 12,000 skeletons of individual animals,” Dr. Anneke Janzen, an assistant professor in UT’s Anthropology Department, told WBIR.
In throwback to early naturalist techniques, The Big Camera helps us picture plants under the sun

Lessons in early and enduring photo techniques are an organic way to spread the arts and cultivate love of nature
KNOXVILLE — Donna Moore and Anna Lawrence showed people how to take photos with the sun.
The method, demonstrated this spring at Ijams Nature Center, involved putting one or more leaves on photo paper and spraying it with two sprays. One spray contained lemon and water. The other contained water with vinegar.
Children then placed these leaves on wet photo paper in the sun. The sun’s light gives a permanent impression of the leaf on the paper.
Knoxville kids go beast mode at new natural playscape

New Ijams playground reconnects kids with neighborhood woods, forts and creeks of yore
KNOXVILLE — Ijams Nature Center officially opened a portal into pure childhood beast mode this week.
The Ijams Nature Playscape at Grayson Subaru Preserve is specifically designed for young children to play in a creek, climb hills, dig, build, crawl and engage with nature in an organic, unstructured way. The new space features a large nest, tunnels, log steps and different rooms to play in.
“For generations, many of us had the opportunity to roam and play in the woods, empty lots and fields that surrounded our homes and neighborhoods,” Ijams Executive Director Amber Parker said. “We remember the freedom we had to use our imagination, test ourselves and become a part of the natural landscape, at least until we were called home for dinner.”

Tennessee Aquarium releases endangered sturgeon on a fin and a prayer
CHATTANOOGA — Lake sturgeon are living fossils.
They are dinosaur fish. They have no scales. They are protected by a tough skin with boney plates, and are unchanged for millennia. They are part of a widespread related group of fish, with 23 species worldwide, and are an endangered species in Tennessee.
Tennessee Aquarium staff released some of these dinosaurs into the Tennessee River here on Earth Day, observed this year on April 22. Aquarium staff were joined by 30 students from Calvin Donaldson Elementary School and the public to release 65 juvenile lake sturgeon into the Tennessee River at Chattanooga’s Coolidge Park.

Help give thanks across history to founders of the South Knoxville nature center and celebrate the addition of 3 acres
Cindy Hassil is a writer for Ijams Nature Center.
KNOXVILLE When H.P. and Alice Ijams purchased 20 acres of land along the Tennessee River in 1910, they couldn’t have known their family would still be contributing to the legacy that would become the 318-acre nonprofit Ijams Nature Center more than a century later.
Ijams Nature Center will celebrate the contributions of the Ijams family and dedicate three acres of land recently donated to the nature center by H.P. and Alice’s granddaughter, Martha Kern, at 10 a.m. Thursday, April 28. The public is invited.
