Giant isopods can roll themselves up into a ball to protect their soft bellies, akin to the protection mechanism of their on-land relative, the roly-poly.

Science in the field gets even more delightful. Two different missions are in the field right now, studying snow and how it affects communities around the country.
From our Wallops Flight Facility in Virginia, the IMPACTS mission is flying up and down the East Coast, investigating how snow forms inside clouds. In Grand Mesa, Colorado, SnowEx’s teams on the ground and in the air are taking a close look at how much water is stored in snow.
Hate going out in the storm? The IMPACTS mission can help with that! IMPACTS uses two planes – a P-3 Orion and an ER-2 – flying through and high above the clouds to study where intense bands of snowfall form. Better understanding where intense snow will fall can improve forecast models down the road — helping prepare communities for snowstorms.
Cameras mounted on the wings of the P3 took microscopic images of snowflakes, like this one.
At the same time, the SnowEx team is in Colorado, studying the depth and density of snow. Researchers are making radar spirals with snowmobiles and working in giant snow pits to measure things like snow water equivalent, or how much water is stored in snow.
SnowEx is helping us better understand snow’s role in ecosystems and human systems, like irrigation for agriculture. If you want to bring some corn for popping, SnowEx’s science can help grow that crop.

That’s no unicorn…it’s the Horned Screamer (Anhima cornuta)! This South American bird, which can be spotted in the lowlands of the Amazon forest, sports a bonafide horn on its head. Made of cartilage, the horn grows as the bird ages and sometimes even breaks off—then grows back over time. Both males and females have them, and they’re thought to be ornamental. Horned Screamers are mainly herbivorous, but do snack on insects.

The Tasmanian devil (Sarcophilus harrisii) needs no introduction. This rambunctious animal is known for its bold temper, haunting calls, and impressive bite. It’s the world’s largest extant carnivorous marsupial, and it eats almost anything it comes across—bones and all! It mainly scavenges carrion, playing an important role in its ecosystem by helping to “clean up” any carcasses. But it also hunts small mammals, birds, and reptiles from time to time.

There’s some snow on the sand and the water’s a little chilly, but that doesn’t mean you shouldn’t stop by and explore Sleeping Bear Dunes National Lakeshore in Michigan. Celebrating its 50th anniversary this year, the park is home to lush forests, clear inland lakes, unique flora and fauna and the namesake sandy bluffs that tower 450 feet over the stunning blue waters of Lake Michigan. We love these gorgeous winter views almost as much as the free ranger-led snowshoe hikes. Have fun. Photo by National Park Service.
