POLIO Last spring a strain of wild polio virus was unexpectedly discovered in the sewage system of Strasbourg, France. It's likely that the virus, considered extinct in that country, had escaped from one of Strasbourg's many biomedical laboratories. Still, the appearance of wild polio in a certified polio-free region undermined World Health Organization plans to eliminate universal vaccination once it declares polio eradicated, which it had hoped to do by 2005. Widespread on five continents, including the Americas, Europe and Asia, through the late 1980s, polio has been contained mostly to parts of sub-Saharan Africa...
...Europe who are engaged in a range of "assisted reproduction" conservation strategies. These include artificial insemination and in vitro fertilization. In particular, though, Noah's arrival will hearten the scientists at ACT, who recently signed a deal with Spanish officials to attempt to clone the bucardo, an extinct mountain goat native to the Pyrenees. The last bucardo died a year ago, struck by a falling tree in its final habitat, northern Spain's Ordesa National Park. Scientists had already preserved a quantity of its cells, and ACT hopes to transfer them into other goats' eggs, perhaps later this year...
After years of watching one species after another become extinct, researchers are sounding optimistic. "We don't have the right to do nothing," says Mauget, who predicts that interzoo exchanges of sperm, oocytes and embryos will develop rapidly. "Instead of shipping our animals from one zoo to another, we'll be sending sperm to the four corners of the earth." Meanwhile, in a corner of Iowa, another kind of delivery is awaited...

...pumped billions of tons of greenhouse gases into the air, altering atmospheric chemistry and appreciably warming the planet in just a few decades. And as our population began the year 2000 above the 6 billion mark, still spreading across the continents, dozens of animal and plant species were going extinct every day, including the first primate to disappear in more than 100 years, Miss Waldron's red colobus...
