Fallen bridges hamper Guatemala storm rescue
June 2, 2010 06:15 AM - Herbert Hernandez, Reuters

Collapsed roads and highway bridges complicated rescue efforts in Guatemala on Tuesday after Tropical Storm Agatha drenched Central America, burying homes under mud and killing at least 180 people. Dozens of people were still missing and rescue teams struggled to reach remote rural communities after the storm cut off roads and destroyed up to 18 major road bridges and dozens of smaller footbridges. "We're trying to get to the communities but we're finding that bridges are down and we have to walk, so it is taking so much longer," said firefighter Rony Veliz. Some 35,000 people remained in emergency shelters three days after Agatha, the first named storm of the 2010 Pacific hurricane season, hit western Guatemala, dumping more than 3 feet (1 meter) of rain in places and raising concern over the coffee crop there and in El Salvador.

Brief exercise reduces impact of stress on cell aging
June 1, 2010 03:23 PM - Elizabeth Fernandez, University of California Newsroom

Exercise can buffer the effects of stress-induced cell aging, according to new research from UCSF that reveals actual benefits of physical activity at the cellular level. The scientists learned that vigorous physical activity as brief as 42 minutes over a three-day period, similar to federally recommended levels, can protect individuals from the effects of stress by reducing its impact on telomere length. Telomeres (pronounced TEEL-oh-meres) are tiny pieces of DNA that promote genetic stability and act as protective sheaths by keeping chromosomes from unraveling, much like plastic tips at the ends of shoelaces.

Dust storms not sole reason for Phoenix air quality
May 31, 2010 11:41 AM - Roger Greenway, ENN

Under the Clean Air Act, states must develop State Implementation Plans (SIP) to convince the US EPA that they can meet the National Ambient Air Quality Standards (NAAQAS). The U.S. Environmental Protection Agency (EPA) rejected Arizona's claim that dust storms caused the high pollution readings in Phoenix in 2008, a decision which could have significant implications for the State. Arizona is currently not meeting the NAAQAS for fine particulate matter, PM- 10 (one-seventh the width of a human hair). Major concerns for human health from exposure to PM- 10 include: effects on breathing and respiratory systems, damage to lung tissue, cancer, and premature death. The elderly, children, and people with chronic lung disease, influenza, or asthma, are especially sensitive to the effects of particulate matter.

Arizona's Smoking Ban Reduced Hospital Visits
May 26, 2010 08:59 AM - Science Daily

ScienceDaily (May 23, 2010) — Two University of Arizona researchers have studied the relationship between Arizona's 2007 law that bans smoking in public places and hospitalization rates for a range of ailments related to secondhand smoke exposure. Their results: Admissions for acute myocardial infarction or AMI, stroke, asthma and angina decreased following the implementation of the ban.

The Deepwater Oil Release Impact on Marine Life
May 25, 2010 03:36 PM - Andy Soos, ENN

New reports are surfacing every day about the immediate impacts of the Deepwater Horizon oil spill on Gulf Coast wildlife, especially as the oil reaches the sensitive marshlands along the coast. What will be the long term impact to local marine life? There is some knowledge from earlier releases such as Valdez off Alaska. Oil contains complex hydrocarbons and heavy metals. Such materials will be absorbed and have impact on the local marine life over time. How they will be absorbed, how much and their effects are unknown or debatable. To begin to address this issue, Academy scientist Peter Roopnarine is working with Laurie Anderson from Louisiana State University and David Goodwin from Denison University to collect and analyze three different types of mollusks from the Gulf Coast. These animals are continually building their shells, and if contaminants are present in their environment, they can incorporate those compounds into their shells.

A New Source Of Dioxins: Anti-Bacterial Soap Combining with Chlorine in Wastewater Sewage Plants
May 25, 2010 08:47 AM - Janet Raloff, Science News, Organic Consumers Association

Manufacturers have been adding the germ fighter triclosan to soaps, hand washes, and a range of other products for years. But here's a dirty little secret: Once it washes down the drain, that triclosan can spawn dioxins. Dioxins come in 75 different flavors, distinguished by how many chlorine atoms dangle from each and where those atoms have attached (their locations indicated by the numbers in the front part of a dioxin's name). The most toxic is 2,3,7,8-tetrachlorodibenzo-p-dioxin, or TCDD. Some related kin bearing four to eight chlorines are also toxic, just less so.

Clean Up the Trucks
May 24, 2010 03:46 PM - Andy Soos, ENN

About a year ago the President and car company CEOs, announced the first Corporate Average Fuel Economy (CAFE) standards for cars and light trucks that took into account greenhouse gas emissions as a factor. The move ordered a 30 percent increase in fuel efficiency by 2016, totaling a 35.5 miles per gallon average for both cars and light trucks. This past Friday’s directive ordered federal agencies to begin development of even more stringent standards for 2017 and beyond. Though big rigs represent less than five percent of all vehicles on U.S. highways, they consume more than 20 percent of the total of transportation fuels utilized. Truck fuel consumption tends to be presently less than 10 miles per gallon which makes them comparatively fuel inefficient.

Nuts Lower Cholesterol, Study Finds
May 24, 2010 09:14 AM - LiveScience Staff

A diet with nuts, including pistachios, significantly lowered total and LDL-cholesterol levels, in addition to triglycerides, a new study found. The finding, published earlier this month in the Archives of Internal Medicine, confirms other evidence that nuts can help reduce the risk of cardiovascular disease, researchers said.

The Great No Fishing Area
May 19, 2010 12:45 PM - Andy Soos, ENN

The National Oceanic and Atmospheric Administration (NOAA) has extended the boundaries of the closed fishing area in the Gulf of Mexico into the northern portion of the loop current as a precautionary measure to ensure that seafood from the Gulf will remain safe for consumers. Though the latest analysis shows that the bulk of the oil remains dozens of miles from the loop current, the new boundaries address the possibility that a tendril of light oil has entered or will enter the loop current. Part of the Gulf Stream, the Loop Current is a warm ocean current in the Gulf of Mexico that flows northward between Cuba and the Yucatan peninsula, moves north into the Gulf of Mexico, loops west and south before exiting to the east through the Florida Straits.

Long-Lasting Sensory Loss in World Trade Center Workers from Airborne Toxins After 9/11 Attacks
May 19, 2010 08:57 AM - Science Daily

New research from the Monell Center and collaborating institutions reports that workers exposed to the complex mixture of toxic airborne chemicals following the 9/11 attacks on the World Trade Center in New York City had a decreased ability to detect odors and irritants two years after the exposure.
