What Is a Spinal Cord Injury?

Although the hard bones of the spinal column protect the soft tissues of the spinal cord, vertebrae can still be broken or dislocated in a variety of ways and cause traumatic injury to the spinal cord.

Tick-Tock Atomic Clock

Modern navigators rely on atomic clocks. Instead of old-style springs or pendulums, the natural resonances of atoms -- usually cesium or rubidium -- provide the steady 'tick' of an atomic clock. The ... Continue reading

Smallpox, Chickenpox . . . Monkeypox?

SmallpoxChickenpoxMonkeypoxThis past summer a few people in the midwest came down with monkeypox, a viral disease related to smallpox but less infectious and a lot less deadly to humans. Oddly they all seem to have caught the disease from domesticated prairie dogs, which have become increasingly popular as pets. Like chickenpox, monkeypox causes fever, swollen lymph nodes, and a rash. Like smallpox and chickenpox, the spots can leave scars. Most people recover from monkeypox, but it is occasionally deadly.

Monkeypox is not usually found in North America. It is normally found in the rainforests of Africa, where it infects squirrels, rodents (and of course monkeys). It is assumed that the Wisconsin prairie dogs caught it at the pet store from exotic pets imported from Africa, possibly giant gambian rats (yes, some people consider these pets).

To prevent the virus from entering the wild rodent population in this country, the Centers for Disease Control banned the importation of rodents from Africa and set out strict guidelines for handling and quarantining suspected cases in pets. By the end of July there had been 37 confirmed monkeypox cases in humans, but there have been no more cases in this country since then.
