How Physical Ability Affects Death
September 10, 2010 12:26 PM - Andy Soos, ENN
There has been much already said about how being physically fit promotes better health and long life. Apparently such positive benefits can be seen in much smaller every day activities. People who are better at simple physical acts such as gripping, walking, rising from a chair and balancing on one leg are more likely to live longer, according to a new study published on bmj.com today.
Flying Fish Aerodynamics

There is widespread knowledge of airborne creatures taking to the water. Everybody knows about ducks and geese, penguins, and seabirds that dive for their prey. But, there is scant attention for the seaborne creatures that take to the air. Flying fish really do fly. A new study published in the Journal of Experimental Biology takes a look at how these amazing animals do what they do.
Methane Reduction from Cattle

Methane is a significant green house gas that can lead to global warming. It is also commonly produced by many animals including humans and cattle. Cow belches, a major source of greenhouse gases, could be decreased by an unusual feed supplement developed by a Penn State dairy scientist.

Termites are a group of social insects usually classified at the taxonomic rank of order Isoptera. Along with ants and some bees and wasps which are all placed in the separate order Hymenoptera, termites divide labor among gender lines, produce overlapping generations and take care of young collectively. They live in giant mounds in Africa. Scientists have discovered that the size and distribution of termite mounds in South Africa can be used to predict ecological shifts from climate change. The research is published in the advanced online edition of Nature Communications.
Potomac River Vegetation Showing Strong Signs of Recovery
September 8, 2010 10:25 AM - David A Gabel, ENN
The Potomac, which runs through the heart of the United States Capital, has suffered centuries of environmental degradation. Water quality has declined steadily as more humans have populated its watershed. However, according to new research, the river is beginning to benefit from restoration efforts that have improved water clarity and reduced nutrient overload. The result has been a ten-fold increase in native submerged aquatic vegetation (SAV). This SAV consists of plant life below the water surface which is an important habitat for fish and other marine life.
As Greenland Melts
September 7, 2010 03:11 PM - Andy Soos, ENN
The Greenland ice sheet is a vast body of ice covering 660,235 square miles, roughly 80% of the surface of Greenland. It is the second largest ice body in the World, after the Antarctic Ice Sheet. The ice sheet is almost 1,500 miles long in a north south direction, and its greatest width is 680 miles at a latitude of 77°N, near its northern margin. Scientists investigating the geophysical and hydrological conditions beneath the Greenland ice sheet say their analysis will be vital for helping understand how the massive ice sheet will respond to climate change.
The Role of Clouds on Earth's Climate
September 7, 2010 10:22 AM - David A Gabel, ENN
Modeling for climate change is an extremely complex process because Earth's climate is so complex. It is an interrelated system that involves the atmosphere, biosphere, land, and oceans. A change in one can cause a chain reaction in all the others. By studying ancient climate change patterns, scientists are better able to predict what might happen in future events. However, one factor that remains far from understanding is the role of clouds — how they will react to and influence a changing climate.
Once More in the Gulf of Mexico
September 3, 2010 02:54 PM - Andy Soos, ENN
The National Oceanic and Atmospheric Administration (NOAA) today reopened to commercial and recreational fishing 5,130 square miles of Gulf waters stretching from the far eastern coast of Louisiana, through Mississippi, Alabama, and the western Florida panhandle. The Mariner Energy oil platform just had an explosion is about 250 miles from today's reopening. The fire on a Mariner Energy Inc. oil and natural-gas platform in the Gulf of Mexico has been extinguished in an event that may prolong the U.S. drilling moratorium imposed after BP's record crude spill.
EPA Disapproves Certain Aspects of Texas' Clean Air Program
September 3, 2010 10:26 AM - David A Gabel, ENN
Every state government has their own agency for the protection of the environment which they operate in conjunction with federal laws and statutes. When those state laws do not match up with their federal counterparts, the potential for conflicts increase. A recent example of this is the Texas Commission on Environmental Quality's (TCEQ) clean-air permitting program. The US Environmental Protection Agency (EPA) has declared that certain aspects do not meet federal Clean Air Act requirements.

Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast September 2. NASA's Tropical Rainfall Measuring Mission satellite observed the high rates rain was falling within Earl in some areas more than 2 inches per hour. Hurricane Earl became the most powerful hurricane of the 2010 Atlantic season early on September 2 when its sustained winds reached 120 kts (~138 mph). It was still intensifying when the TRMM satellite passed near its location on 2 September 2010. The TRMM Microwave Imager data were used in the rainfall analysis that showed heavy rainfall, particularly in the northwest quadrant of Earl's very distinct circular eye.
