The Paluweh Volcano, also referred to as the Rokatenda Volcano, has been busy since late 2012. This stratovolcano, located in Indonesia, just erupted in early August of 2013, killing at least five people. Unfortunately, many news media outlets are characterizing the most recent eruption as a lava flow, which is scientifically inaccurate. The eruptive behavior is that of a pyroclastic flow.

An excellent interdisciplinary article that explains how chronicles written by religious men in Ireland hundreds of years ago have helped scientists draw a link between frigid periods of the country's history and volcanic eruptions.

The latest trend in urban renewal involves opening up underground streams. There's likely an underground stream in your city, but it may soon be seeing the light. Uncovering buried streams has had huge impacts in places as diverse as Seattle, Washington, Kalamazoo, Michigan, and even Seoul, Korea—improving local water quality, providing habitat for fish and birds, and turning neglected parking lots and roads into public parks that boost neighbors' property values and can revitalize entire cities. And city planners everywhere are starting to take note.
Climate change alters the way in which species interact with one another--a reality that applies not just to today or to the future, but also to the past. "We found that, at all time scales, climate change can alter biotic interactions in very complex ways," said paleoecologist Jessica Blois of the University of California, Merced, the study's lead author. "If we don't incorporate this information when we're anticipating future changes, we're missing a big piece of the puzzle."
Researchers study how various sizes, shapes of volcanic ash travel through the atmosphere.

Most apes eat leaves and fruits from trees and shrubs. But new studies show that human ancestors expanded their menu 3.5 million years ago, adding tropical grasses and sedges to an ape-like diet. The change set the stage for consuming more modern fare: grains, grasses, and meat and dairy from grazing animals.
