Scientists have confirmed that prions, the mysterious proteins thought to cause chronic wasting disease (CWD) in deer, latch on tightly to certain minerals in soil and remain infectious.

The discovery that prions stay deadly despite sticking to soil comes as a surprise, because while many proteins can bind to soil, that binding usually changes their shapes and activities.

After a long incubation period, deer and elk infected with CWD suffer neurological and behavioral problems such as staggering, shaking, and excessive salivation and urination. Over time, the animals literally waste away, often dying in woods and fields. Originally detected in the 1960s in Colorado and Wyoming, CWD is now present in 14 states and two Canadian provinces.
