Satellite Warning System of Natural Disasters
September 15, 2010 01:29 PM - Andy Soos, ENN
Looking down upon the Earth gives one the big picture. Up high in the sky are many man made satellites that are designed to look down and send information to various places. NASA is currently designing a pair of robotic probes to keep tabs on how the planet is changing and to help forecasters predict natural disasters, such as volcanic eruptions, earthquakes and landslides.
How to Save the Wild Tiger
September 15, 2010 10:52 AM - David A Gabel, ENN
Tigers, like most big cats of the world, are in retreat. In the past, tigers were found all throughout Asia, from the Caspian Sea to Siberia and Indonesia. Now they occupy only six percent of their former range. In the last decade alone, tiger-occupied area has decreased by 41 percent. Despite decades of conservation initiatives, the number of tigers in the wild is at an all-time low. According to a new study from an international team of researchers, efforts should be concentrated on a few key sites in order to save the species from extinction.
Jupiter Bright Spots
September 14, 2010 03:10 PM - Andy Soos, ENN
The sky is not quite unchanging, just slow and far away. Jupiter, the largest planet in the solar system, catches a lot of the meteors, comets and other sky debris and in that way protects the inner planets such as Earth. Amateur astronomers working with professional astronomers have spotted two fireballs lighting up Jupiter's atmosphere this summer, marking the first time Earth based telescopes have captured relatively small objects burning up in the atmosphere of the giant planet. The two fireballs - which produced bright freckles on Jupiter that were visible through backyard telescopes - occurred on June 3, 2010, and August 20, 2010, respectively.
Fourth Hottest Summer on Record for the United States in 2010
September 14, 2010 10:01 AM - David A Gabel, ENN
As September begins to bring cooler temperatures, Americans can look back objectively at the past summer (June-August). The above average temperatures in the contiguous states combined to make it the fourth warmest ever. Only seven of the lower 48 states had normal temperatures, and 29 were much above normal. This news is detailed in the National Oceanographic and Atmospheric Administration's (NOAA) State of the Climate report issued on September 8, 2010.
Early Life on Earth and Amino Acids
September 13, 2010 02:54 PM - Andy Soos, ENN
A comet is an icy small Solar System body that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. Occasionally, they will collide with planets such as the Earth. New research from Lawrence Livermore National Laboratory scientists shows that comets that crashed into Earth millions of years ago could have produced amino acids — the building blocks of life. Amino acids are critical to life and serve as the building blocks of proteins, which are linear chains of amino acids.
Toxic Algae Killing Sea Otters
September 13, 2010 11:06 AM - David A Gabel, ENN
A toxin produced by a type of cyanobacteria, also known as blue-green algae, has been devastating a colony of sea otters off the coast of California. In a paper published in the journal, PLoS ONE, by the California Department of Fish and Game (DFG) and the University of California (UC), Santa Cruz, researchers link the deaths of over 21 California sea otters to toxic chemicals from algae flowing into the ocean.

Yellowstone Park is a somewhat dormant super volcano site full of fuming vents and hot geysers. A plume of molten rock rising from deep beneath Yellowstone National Park is probably what is fueling the region's volcanic activity, as well as tectonic plate oddities across the Pacific Northwest, new research suggests.
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
September 10, 2010 10:45 AM - David A Gabel, ENN
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
September 9, 2010 04:30 PM - Andy Soos, ENN
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.
