...Weird Wonders Inside locked cabinets at the Smithsonian Institution nestle snapshots in stone as vivid as any photograph. There, engraved on slices of ink-black shale, are the myriad inhabitants of a vanished world, from plump Aysheaia prancing on caterpillar-like legs to crafty Ottoia, lurking in a burrow and extending its predatory proboscis. Excavated in the early 1900s from a geological formation in the Canadian Rockies known as the Burgess Shale, these relics of the earliest animals to appear on earth are now revered as priceless treasures. Yet for half a century after their discovery, the Burgess Shale fossils...
...Genetic Tool Kit The animals that aerated the Precambrian oceans could have resembled the wormlike something that left its meandering marks on the rock Erwin lugged back from Namibia. More advanced than a flatworm, which was not rigid enough to burrow through sand, this creature would have had a sturdy, fluid-filled body cavity. It would have had musculature capable of strong contractions.

What kind of genetic machinery, Erwin wondered...
Hackers regularly cruise the Internet looking for prey. But when they try to burrow into the CIA's secrets through its electronic link to that network, they face the ultimate barrier: the "air gap," says a senior intelligence official.

Maybe so, but meterologists are predicting a winter storm on the east coast this weekend...
...this disorder is caused by the decrease in light [that occurs during the winter]," Heatherton said. "Studies have measured people's moods from season to season and found many to be feelings sad and dysphoric during winter." This might explain the peculiar winter phenomenon characterized by the urge to burrow deep within one's blankets and skip all classes in favor of watching soap operas...
