It has spent some 175 years homeless, wandering many paths of taxonomy without a single branch to call its own. In the time since it was first described, this now-extinct, cone-shaped sea creature has known a number of presumed families — from mollusks to designations much more nebulous — but the tiny hyolith never quite fit in any of them.

Oklahoma lawmakers are staring into a budget hole that's nearly $900 million deep — and they might not be able to cut their way out of it. Legislators are considering tax increases to help fund state government, and one idea is gaining traction: Hiking taxes on gasoline and diesel.

Waukesha reports that it is in full steam ahead mode with plans to deliver Lake Michigan water to its residents. At the meantime, a consortium of U.S. and Canadian mayors, the Great Lakes St Lawrence Cities Initiative, are fighting to halt the project.

While the Compact Council already cast its unanimous support in favor of Waukesha last summer, the body will listen to both sides in the next month or so.

The tiny village of Newtok near Alaska's western coast has been sliding into the Ninglick River for years. As temperatures increase — faster there than in the rest of the U.S. — the frozen permafrost underneath Newtok is thawing. About 70 feet of land a year erode away, putting the village's colorful buildings, some on stilts, ever closer to the water's edge.

West Coast crab fishermen just ended an 11-day strike over a price dispute. But a more ominous and long-term threat to their livelihood may be on the horizon. A new study in the Proceedings of the National Academy of Sciences has found a link between warming ocean conditions and a dangerous neurotoxin that builds up in sea life: domoic acid.

Beijing is launching a new police force aimed at tackling its persistent smog problem.

This comes after a month of particularly severe air quality that left the capital and dozens of other Chinese cities blanketed in thick, brown smog.

Seven years ago, the Navajo tribal council in southeastern Utah started mapping the secret sites where medicine men and women forage for healing plants and Native people source wild foods. They wanted to make a case for protecting the landscape known as Bears Ears, a place sacred not only to their tribe but to many other tribes in the region, going back thousands of years.

A powerful winter storm in California has brought down an ancient tree, carved into a living tunnel more than a century ago.

The "Pioneer Cabin Tree," a sequoia in Calaveras Big Trees State Park, saw horses and cars pass through it over the years. More recently, only hikers were allowed to walk through the massive tree.

Over the weekend, a powerful winter storm slammed into California and Nevada, prompting flooding and mudslides in some regions. The Associated Press reports it might be the biggest storm to hit the region in more than a decade.

When South Korea's mountain town of PyeongChang hosts the Olympic and Paralympic Winter Games next year, a white tiger and a black bear, respectively, will serve as mascots. They've been introduced as cuddly icons of Korean history and folklore.
