...kens annually. The IBDV strains found there caused wasting away of the bursa, which is the major immunological organ of chickens, but did not cause the hemorrhaging condition and high death rates of earlier, so-called classic, strains found in the United States in the 1960's.

...Also known as prion diseases, they include chronic wasting disease in deer and elk and Creutzfeldt-Jakob disease in humans. The hallmark of TSE diseases is misshapen protein molecules that clump together and accumulate in brain tissue. Normal forms of these molecules, called prion protein, reside on the su...Scientists record extraordinary sounds made by minke whales
... of dwarf minke whales, people told them they were wasting their time. There were very few reports of minke whale vocalizations, and some experts believed the species rarely made any sounds at all.

... The birds still went to the full flowers, without wasting energy on empty ones. Irwin has some more theories to test on why the birds pick the right flowers. One is that their wingbeats make the flowers vibrate, and full flowers have a different frequency to empty ones.

Muscular Dystrophy (DMD), the catastrophic muscle wasting disease that strikes thousands of boys in the United States each year.
