EPA Sets Limits on Mercury and Other Air Emissions from Cement Kilns
August 11, 2010 04:44 PM - Roger Greenway, ENN
Cement plants emit mercury from the kilns used in the cement manufacturing process. Cement kilns operate at high temperatures, and are, in fact used to destroy many types of toxic substances. The rule, proposed on August 9, 2010 also applies to total hydrocarbons (THC), and particulate matter (PM) from new and existing kilns located at major and area sources, and for hydrochloric acid (HCl) from new and existing kilns located at major sources. The standards for new kilns apply to facilities that commence construction, modification, or reconstruction after May 6, 2009 The U.S. Environmental Protection Agency (EPA) issued final rules to cut emissions of mercury, particle pollution and other harmful pollutants from Portland cement manufacturing, the third-largest source of mercury air emissions in the United States. EPA calculates that the rules will yield $7 to $19 in public health benefits for every dollar in costs.
The Fish May Now Return

The Gulf of Mexico has been a problem for fishing and other marine life even since the BP oil spill earlier this year. Things are looking up finally. The National Oceanic and Atmospheric Administration (NOAA) has just reopened 5,144 square miles of Gulf waters to commercial and recreational finfish fishing. Since July 3, NOAA data have shown no oil in the newly reopened area, and United States Coast Guard observers flying over the area in the last 30 days have also not observed any visible oil. Even more importantly, fish caught in the area and tested by NOAA experts have shown no signs of contamination.
Harvesting Indonesian Ice

Ice can exist on the equator, so long as it's at a high elevation. The Indonesian mountain ridge, which rises to 16,000 feet on the island of New Guinea, supports the presence of such an ice field. According to a study by researchers from Ohio State University, that tropical ice field can disappear within a few years. Their studies also offer clues of the El Nino weather phenomenon that dominates climate variability in the tropics.

Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage. As much as 12 percent of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar. That’s more than what could be offset if the same plants and materials were burned to generate energy, concludes a recent study published in the journal Nature Communications. Biochar could sequester carbon in the soil for hundreds to thousands of years.
Plastic Bag Problems in India
August 9, 2010 02:46 PM - Andy Soos, ENN
Plastic shopping bags, carrier bags or plastic grocery bags are a common type of carryall used in several countries. Most often these bags are intended for one single use to carry items from a store to a home. Before then paper bags were most commonly used. The real change in grocery bags did not start until 1982, when the two of America’s largest grocery companies Safeway and Kroger started replacing paper bags with plastic bags. These bags are useful and inexpensive but can cause numerous other problems. In India a new concern has arisen.
Accusations of Flawed Climate Science are Rejected by the EPA
August 9, 2010 12:43 PM - David A Gabel, ENN
Since the Obama Administration came to power in Washington, the EPA has taken upon itself the mission of addressing global climate change. They have been very proactive in getting information out confirming that climate change exists and that it is caused, at least in part, by human activities. Ten petitions were sent to the agency to challenge the EPA's position on climate change. Upon review, the EPA has decided to fully reject the claims made in the petitions, determining that they are without merit.
NOAA Solution to Lionfish Invasion, eat them!
August 8, 2010 10:28 AM - Roger Greenway, ENN
A new NOAA study looking at how to curb the rapid growth of lionfish, an invasive species not native to the Atlantic Ocean, suggests that approximately 27 percent of mature lionfish will have to be removed monthly for one year to reduce its population growth rate to zero. But the good news is that the invasive fish happens to be delicious—and NOAA is encouraging chefs to find new ways to introduce it to U.S. consumers. Lionfish are native to the western and central Pacific Ocean, but have established themselves from North Carolina to South America. They are a popular aquarium fish that were likely first released in Florida waters in the mid-1980s. Since then, the species has spread rapidly. Scientists and public officials are seriously concerned at the effect lionfish are having on reef ecosystems, since this predator is capable of rapid population growth and outcompeting native fish for food and territory.
Prayer and Health
August 6, 2010 12:25 PM - Andy Soos, ENN
There has always been a desire in the spirits of human beings to hope and sometimes believe in the effects of prayer in healing. Belief and the subsequent proof has always been hard to find or to do. Findings from a new international study of healing prayer suggest that prayer for another person's healing just might help -- especially if the one praying is physically near the person being prayed for. Candy Gunther Brown, an associate professor in the Department of Religious Studies at Indiana University Bloomington, led the study of proximal intercessory prayer for healing.
New Findings on the H1N1 Virus

Does anybody still remember swine flu? It caused a big uproar last winter and sent millions of people to their doctors to request the Tamiflu vaccine. New findings on the virus have been uncovered by researchers at the University of Wisconsin-Madison. They found that the H1N1 virus used a new biochemical trick to spread rapidly among humans and cause an epidemic. The structure of the virus evolved to allow it to interact with the cellular structure of mammals.
The Views of Mars
August 5, 2010 04:40 PM - Andy Soos, ENN
Of all the planets in our solar system Mars has always been the one most dreamers think of. Many science fiction myths have been based on Mars such as Edgar Rice Burroughs Barsoom and its many canals as well as the Ray Bradbury Martian Chronicles. All dreamed of a friendlier Mars than has been found. Now all can see detailed images of Mars. The latest set of new images from the telescopic High Resolution Imaging Science Experiment Camera on NASA's Mars Reconnaissance Orbiter offers detailed views of diverse Martian landscapes.
