...Yellowstone Caldera - formed by the massive upheaval 642,000 years ago that spread airborne debris all the way to the Gulf of Mexico - is nowhere close to being extinct. Areas of the park's topography inflate like a bellows because of magma infusing into volcanic chambers about 6 miles below the surface. About 1,000 to 2,000 tremors a year (mostly small) have been recorded since 2004, when interpretation of satellite imagery with GPS readings indicated the caldera had been rising as much as 3 in. a year. The past week's number of tremors - about 400 - is considered...

...benefit, however, is predicated on annual inoculation. Annual flu shots are necessary because the flu mutates much more quickly than other viruses like the measles or polio. Part of the reasons those diseases are now so rare or nearly extinct is that, in the U.S., infants are vaccinated against them while still in the hospital, keeping them inoculated for life...

...estimated global sales of 61,000 tons of bluefin tuna - and even from this year's official quota of about 29,000 tons - but it's still far above the 15,000 tons that marine scientists advise is the limit that can be fished without the species becoming extinct...

Nature may have forgotten about the extinct woolly mammoth, but science has been buzzing about it lately, ever since researchers announced that they had sequenced 80% of its genome. That gave rise to chatter about whether a cloned mammoth could ever be born. Serious cloning science began in 1952, when researchers first reported transferring a tadpole nucleus into an ovum and producing identical tadpole copies. In 1995, biologist Craig Venter sequenced the genome of the Haemophilus influenzae bacterium, the first living organism whose genes were decoded. In 1997, cloning made stop-the-presses headlines when embryologist Ian Wilmut announced that...
