An unusual swarm of volcanic eruptions over the last 14 years may be partially responsible for the slowing of global warming, a new report suggests. The 17 eruptions from 1998-2012 pumped sulfur dioxide into Earth's upper atmosphere, where it formed liquid particles that reflected more sunlight back to space, moderating the larger-scale warming of the planet surface, according to the study published online Monday in Nature Geoscience.

For 100,000 years, a pod of cool magma has been sitting mostly immobile beneath the Mt. Hood volcano. Consider it cold storage. As long as the magma stays cool, the volcano will not erupt. Cool magma is like peanut butter straight from the fridge - difficult to move. But if the conditions are right, that magma can liquefy in just a few months, potentially leading to an eruption, according to new research. Hot magma from deep in the Earth's crust bubbles up, mixes with the cool magma and causes it to liquefy.

At least three people were killed and tens of thousands forced to flee their homes when a volcano erupted on Indonesia's most populous island, shutting down airports and showering the region with ash and grit. The eruption of Mt. Kelud in Java began late Thursday night and could be heard as far as 125 miles away, according to local news reports . “The eruption sounded like thousands of bombs exploding,” Ratno Pramono, a 35-year-old farmer from the nearby village of Sugihwaras, told the Associated Press.

In the northeast of China, at the Yixian and Jiufotang formations, scientists have discovered thousands of exquisitely preserved fossils of plants and birds, dinosaurs and mammals. Together they make up the Jehol Biota -- an ecosystem, preserved in ash, that dates back nearly 130 million years. Some of these fossils are so complete that researchers can determine what a dinosaur had for breakfast on the day it died. Others include impressions of an animal's muscles and skin, as well as hair, feathers and scales. The fossils tell us that back in the lower Cretaceous period this land was humid, and dotted with conifer forests and lakes.

It's an idea that's easy to grasp: Justin Vernon onstage in Los Angeles the week before the Grammy Awards. Two years ago, after all, the singer-songwriter and his Wisconsin band Bon Iver were named best new artist at the Grammys, and “Bon Iver, Bon Iver” -- a modest masterpiece of deep-feel introspection -- won the prize for alternative music album. So it seems natural that Vernon would return to town for the annual crush of concerts and parties that takes place during the run-up to “music's biggest night,” set this year for Jan. 26. PHOTOS: Concerts by the Times Only Vernon didn't draw a sold-out crowd to the Fonda Theatre on Saturday with Bon Iver.

We all know that reading a novel can transport you, delight you and intrigue you while you're reading it. Now, thanks research by scientists at Emory University, we know that immersing yourself in a novel causes measurable physical changes in the brain that can be detected up to five days after the reader closes the book. The Emory researchers, in a paper for the journal Brain Connectivity, compared the effect to “muscle memory.” "The neural changes that we found associated with physical sensation and movement systems suggest that reading a novel can transport you into the body of the protagonist," neuroscientist Gregory Berns said, according to a report in the journal Science Codex . "We already knew that good stories can put you in someone else's shoes in a figurative sense.
