Marine Life and Electromagnetism
September 21, 2010 02:46 PM - Andy Soos, ENN
Super sized electromagnetic coils are helping explain how aquatic life might be affected by renewable energy devices being considered for placement along America's coastal waters and in the nation's rivers. An electromagnetic field is a physical field produced by electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The effect on marine life is not known one way or the other.
The US EPA Celebrates Pollution Prevention Week
September 21, 2010 09:48 AM - David A Gabel, ENN
This week, from September 19-25, marks the 20th anniversary of the Pollution Prevention Act of 1990. The old way of doing things was to let companies pollute, and then pay a fortune to try to clean it up. This act states that it is a national policy of the United States to prevent pollution at the source whenever feasible. To honor this anniversary, the EPA is urging the public to recommit to the ideal of preventing pollution in their day-to-day lives.
Sea Mountain Life
September 20, 2010 01:40 PM - Andy Soos, ENN
There are mountains on land and there are mountains under the sea. The vast ocean seems flat but under that water are mountains, valleys and plains. These mountain chains rival the Alps, the Andes and the Himalayas in size and little is known about seamounts, the vast mountains hidden under the world's oceans. Now in a special issue of Marine Ecology scientists uncover the mystery of life on these submerged mountain ranges and reveal why these under studied ecosystems are under threat.
2010: A Hot Year Indeed
September 17, 2010 02:37 PM - Andy Soos, ENN
Weather is always an easy topic of conversation. The first eight months of 2010 tied the same period in 1998 for the warmest combined land and ocean surface temperature on record worldwide. Meanwhile, the June—August summer was the second warmest on record globally after 1998, and last month was the third warmest August on record. Separately, last month’s global average land surface temperature was the second warmest on record for August, while the global ocean surface temperature tied with 1997 as the sixth warmest for August.
Indian Murky Air Quality
September 17, 2010 01:22 PM - Andy Soos, ENN
Data from the Multi-angle Imaging Spectroradiometer (MISR) instrument on NASA's Terra spacecraft have been used in a groundbreaking new university study that examines the concentration, distribution and composition of aerosol pollution over the Indian subcontinent. The study documents the region's very high levels of natural and human-produced pollutants, and uncovered surprising seasonal shifts in the source of the pollution.
Restoring the Chesapeake
September 17, 2010 12:21 PM - Andy Soos, ENN
Reducing the delivery of nutrients to the Chesapeake Bay is one of the most important components of restoration efforts to achieve a healthy Bay ecosystem. The United States Geologic Service (USGS) has developed a new method for tracking the progress toward reducing nitrogen and phosphorus delivery from the watershed to the Bay. When evaluating the quality of the water entering the Bay, this new method takes into consideration seasonality, variations in river flow, and the long-term trends that are driven by the wide range of human activities in the watershed, such as wastewater treatment and changing land management practices.
Cure for Insomnia: Get Moving
September 16, 2010 11:12 AM - David A Gabel, ENN
You've been tossing and turning all night. Rolling over, the clock says 2:30 am. Instead of reaching for the bottle of Nyquil, or something even stronger, researchers from Northwestern University (NWU) have a much healthier alternative to falling asleep — aerobic exercise. Regular cardiovascular exercise can improve the quality of sleep, overall mood and vitality of insomniacs.
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.
