The 500-Pound 'Chicken From Hell' Likely Ate Whatever It Wanted

Thursday, March 20, 2014

OK, maybe it just munched vegetation, small animals and eggs. But this newly named dino looked like a cross between a chicken and a bulked-up ostrich. Five-inch claws? We'd have stayed out of its way.


Centuries Before China's 'Great Wall,' There Was Another

Sunday, December 29, 2013

Archaeologists are now mapping a wall in eastern China that is as much as 15 feet tall in some places, and predates the more famous barrier by 300 years. Hundreds of miles long, it was likely erected to keep neighboring Chinese dynasties from invading each other, historians say.


In Typhoon-Heavy Western Pacific, Preparation Can Only Go So Far

Monday, November 11, 2013

Super Typhoon Haiyan devastated the Philippines, destroying whole towns, killing thousands and displacing more than 600,000 people — and it raises questions about emergency policies and realities in Pacific coastal nations.


How'd They Do That? The Story Of A Giant Rock And A Road Of Ice

Monday, November 04, 2013

Huge stone slabs weighing up to 300 tons that now reside in Beijing's Forbidden City were slid more than 40 miles in 15th- and 16th-century China over water-lubricated ice roads in the dead of winter. Though spoked wheels had been around for almost 3,000 years, the ice roads were smoother and required less manpower.


In Sandy's Wake, Flood Zones And Insurance Rates Re-Examined

Wednesday, October 30, 2013

It's been a year since Hurricane Sandy knocked the mid-Atlantic states for a loop. Scientists say that as sea level rises, such storms are likely to occur more often. But the new, more realistic flood maps could boost flood insurance rates. Will politics trump science?


Immense Underwater Volcano Is The Biggest On Earth

Friday, September 06, 2013

Scientists report in the journal Nature Geoscience that they've uncovered the largest volcano on Earth in the Northwest Pacific Ocean, about 1,000 miles east of Japan. In fact it's one of the largest in the solar system, second only to Olympus Mons on Mars. Scientists have been studying the massive structure for decades, but now are confirming it's a single volcano about the size of New Mexico. It rises about four miles off the sea floor, but doesn't break through the ocean surface. Called Tamu Massif, it hasn't erupted in more than 130 million years, helping to keep its true nature secret.


Wise Old Whooping Cranes Keep Captive-Bred Fledglings On Track

Friday, August 30, 2013

A decade ago, cranes that had never before migrated followed the lead of an ultralight plane to learn the route south. Several generations later, old cranes are teaching young birds to navigate that same route. It's a clue that migration is a combination of nature and nurture, researchers say.


Can A Big Earthquake Trigger Another One?

Friday, August 23, 2013

A new scientific report claims that a powerful quake can, in effect, be contagious. The finding could have important implications for hazard planning in earthquake zones.


Where The Whale Sharks Go

Thursday, August 22, 2013

A nine-year study tracked more than 800 of the massive and largely mysterious whale sharks. For the first time, researchers have tracked the sharks' far-flung migration and where they may go to give birth.


Old Hawaiian Menus Tell Story Of Local Fish And Their Demise

Friday, August 09, 2013

An ecologist wondered if Hawaiian menus might help explain what happened to Hawaii's sea turtle population. But the menus revealed another marine tragedy: that local fish numbers had dropped to about a tenth of what they once were.


Earth Scientists Pin Climate Change Squarely On 'Humanity'

Tuesday, August 06, 2013

The federal government's top climate scientists announced Tuesday that 2012 was really hot — among the top 10 hottest years on record and the hottest ever in the U.S., with rising sea levels, less Arctic sea ice and warmer oceans. And the American Geophysical Union called humanity "the major influence" on global climate change.


Jack Longino, 'The Astonishing Ant Man,' Finds 33 New Species

Thursday, August 01, 2013

All told, the scientist has discovered 131 new species of animals in his career, and some are so scary-looking, he's named them after demons. It's a task that's taken more than 30 years of crawling through rain forests to accomplish, and Longino says he's still only scratched the surface.


Once Resilient, Trees In The West Now More Vulnerable To Fires

Monday, July 29, 2013

Many forests in the American West have evolved with fire, and actually benefit from the occasional wildfire. But researchers are finding that trees that once would survive and thrive with small fires are now losing their ability to do so.


Why The Latest Gulf Leak Is No BP Disaster

Wednesday, July 24, 2013

Deep-sea natural gas reservoirs sometimes contain oil, but experts say it's highly unlikely Tuesday's accident in the Gulf of Mexico would leak anything like the BP spill. And there are signs suggesting the only thing crews have to deal with is leaking gas.


Fighting Fire With Fire: Why Some Burns Are Good For Nature

Sunday, July 21, 2013

Fire is a natural part of the western landscape, and a push over the last century to eliminate fires has threatened the habitats that some plants and animals need. In a Montana valley, fire scientists are trying to show that they can actually save wilderness by burning it.


Wildfires Will Worsen, And Further Strain The Forest Service

Thursday, July 18, 2013

Over the past decade, fires in the American West have grown in intensity and size. "We're on a growth trajectory that is very scary," says one fire tracker. "And if we think it's expensive and dangerous now, we're just now seeing the very beginnings of how big this problem is going to be very soon."


Om Nom Nom: T. Rex Was, Indeed, A Voracious Hunter

Tuesday, July 16, 2013

A fossilized tyrannosaur tooth found lodged between bones in a hadrosaur's tail is giving paleobiologists pretty firm clues about the tyrant king's meal plan. And Hollywood may have been right all along — T. Rex definitely knew how to kill.


Wastewater Wells, Geothermal Power Triggering Earthquakes

Thursday, July 11, 2013

Pumping industrial wastewater into storage wells deep underground can prime nearby faults for an earthquake. And studies show that a large quake — even one on the other side of the planet — can also push faults over the edge and set off a swarm of mini-earthquakes.


Saving One Species At The Expense Of Another

Thursday, July 11, 2013

In Montana's Centennial Valley, conservationists made a grievous mistake while trying to save the trumpeter swan — they nearly wiped out Arctic grayling. Now they're looking for ways to make sure both species get a place on the ark.


In Montana Wilds, An Unlikely Alliance To Save The Sage Grouse

Wednesday, July 10, 2013

The chicken-size sage grouse is as much a part of America's Western range as antelopes and cowboys. The birds nest beneath sagebrush, and as it disappears, so do the grouse. Biologists hope to protect the bird without starting a 21st century range war.
