October 2014 PAESTAR

This month we recognize David Andrews, who teaches general science, environmental science and chemistry at Butler Junior High School in Butler, Pennsylvania. In August, the White House Council on Environmental Quality, in partnership with the U.S. Environmental Protection Agency, announced David as a winner of the annual Presidential Innovation Award for Environmental Educators. In a ceremony at the White House, David was one of 17 teachers from across the nation honored for contributions to environmental education and stewardship.

EARTH: Santiaguito Volcano's Clockwork Behavior Provides an Exceptional Laboratory

EARTH Magazine

From EARTH Magazine  --  If Earth breathes, Santiaguito Volcano in the Western Highlands of Guatemala could be its mouth. Roughly every half hour, like volcanic clockwork, Santiaguito's active Caliente lava dome expands, filling with gas from depressurizing magma below. Then it exhales, often explosively, and deflates. Over the course of a day, you could almost keep time by it.

Listen Current: A Look At Mars' Atmosphere

Listen Current

Last week NASA’s MAVEN probe began orbiting Mars in an effort to measure and map the Martian atmosphere. Today, Mars, known as the red planet, is bone dry and it’s atmosphere is being broken down by the sun’s solar winds, but evidence shows that it was once much more like Earth. From liquid channels to lake beds, there is clear evidence that Mars once had water as well as a magnetic field. So what happened to this water? These are the answers the MAVEN is searching for by mapping Mars’ current atmosphere. Listen to learn more about this important mission.

Listen Current: Arctic Explorer from Franklin Expedition Found

Listen Current

This story, about the discovery of a long lost ship, is a fascinating way to discuss early exploration efforts as well as global warming. In 1845 two ships led by Sir John Franklin left England searching for a northern route across the globe, known as the Northwest Passage. They never returned. 169 years later, a helicopter pilot found a clue that led the Canadian government to one of the missing ships. From sonar imaging to video cameras on submarines, archeologists have confirmed that this is one of the abandoned ships from the famous expedition.

Listen Current: Birds Signal Climate Change

Listen Current

A recent report shows carbon dioxide levels in the atmosphere rose at a record rate in 2013. Humans aren’t the only species affected by these changes. A new report by the National Audubon Society makes it clear that bird species in the U.S. and Canada are at risk of losing their habitats and potentially their lives due to climate change.

NASA's Space Place: Twinkle, twinkle, variable star

NASA's Space Place

By Dr. Ethan Siegel  --  As bright and steady as they appear, the stars in our sky won't shine forever. The steady brilliance of these sources of light is powered by a tumultuous interior, where nuclear processes fuse light elements and isotopes into heavier ones. Because the heavier nuclei up to iron (Fe), have a greater binding energies-per-nucleon, each reaction results in a slight reduction of the star's mass, converting it into energy via Einstein's famous equation relating changes in mass and energy output, E = mc2.

EARTH: Virtual Water - Tracking the Unseen Water in Goods and Resources

EARTH Magazine

From EARTH Magazine  --  "Virtual water" was coined in 1993 to help explain why long-predicted water wars driven by water and food security had not occurred among the arid nations of the Middle East and North Africa. The virtual water notion refers basically to the total amount of freshwater, either from rainfall or irrigation, used in the production of food commodities, including crops and fodder-fed livestock, or other goods and services - agricultural, industrial or otherwise.
