Pseudogout is a joint disease that can cause attacks of arthritis. Like gout, the condition involves the formation of crystals in the joints. But in pseudogout, the crystals are formed from a salt instead of uric acid. Alternative Names. Calcium pyrophosphate dihydrate deposition disease; CPPD disease.
Every autumn, around three million Monarch butterflies will travel around 3,000 miles to inhabit the mountains of central Mexico or small groves of trees along Californiaâs coast.
When the rains arrive, the food plants grow back and the butterflies return. When the late summer and early fall Monarchs emerge from their pupae, or chrysalides, they are biologically and behaviorally different from those emerging in the summer. The shorter days and cooler air of late summer trigger changes.
