A recent study provides the first evidence that global traffic in wildlife and wildlife products poses a significant health risk to humans. Analysis of illegal wildlife products confiscated at U.S. airports confirmed the presence of highly contagious diseases. The majority of emerging infectious diseases originate in wildlife, and contact with wildlife contributes to the spread of pathogens in human populations worldwide. With millions of live wild animals and wildlife products entering the United States each year, this study demonstrates the necessity of refining methods for identifying infectious diseases in wildlife.

Go beyond the basics of field study—use math and science skills and dig in the dirt! Students learn how to count plants as part of a study of local biodiversity and calculating biodiversity indexes.
Major highways that connect Los Angeles and Las Vegas run through major habitats of bighorn sheep. These highways allow travel between Los Angeles and Las Vegas in just four hours, but what do they mean for the sheep?

Video profile of Dr. Clinton Epps, who studies bighorn sheep populations. Includes discussion questions about scientific practice and how scientists use DNA to study populations.
In winter, salt is regularly applied to melt ice on roads in the Northeast. But road salt runoff drains into streams and drinking water. Scientists have been testing freshwater in three regions of the Northeast for thirty years. The salt buildup has made some urban, suburban, and rural streams 25 percent as salty as seawater.
Did you know that when you look at a star, your eyes are capturing light that traveled all the way from the star to your eye? Learn more about how light carries information from distant objects.
