BOZEMAN, Mont. -- High in the Wallowa Mountains of northeastern Oregon, Raina K. Plowright and other researchers blindfolded and hobbled a herd of bighorn sheep in a corral so blood samples could be taken and their noses and throats swabbed.
"There's lots of places for pathogens to hide in the nasal cavity," said Dr. Plowright, a wildlife scientist with the Center for Infectious Disease Dynamics at Penn State who is based in Bozeman.
Peering into the nostrils of wild sheep is part of the nascent field of eco-immunology, which seeks both to understand the immune systems of wild animals and to use that knowledge to gain a better understanding of human immune systems. Until recently, this kind of knowledge has been gleaned almost exclusively by studying pampered, genetically similar lab animals, which don't reflect a real-world scenario.

VIDEO: How Hair Ice Grows
In 2013, American Scientist featured an article on odd ice formations on plant stems, including these curling ribbons of ice. One of the types of ice discussed in the article was hair ice—long, thin strands of ice that grow under quite specific conditions. The only problem is that a new study shows the theory put forth at the time—that gas pressure pushes the water out—isn’t correct... (click the link above to read more).
