Breathing Polluted Air Can Disrupt Immune System
April 19, 2011 09:52 AM - David A Gabel, ENN
Negative health effects from the chronic inhalation of polluted air are well known to cause cardio-respiratory disease. It can be particularly damaging to seniors, children, and people with asthma. Now according to a study from Ohio State University, breathing polluted air can also cause widespread inflammation by triggering the release of white blood cells from bone marrow into the blood stream. The influx of white blood cells can alter the integrity of the blood vessels. The white blood cells are then absorbed into fat tissues where chemicals are released that cause inflammation.

Will electric cars ever become the common way to drive? What is needed is an infrastructure that allows easy recharging of the vehicle (such as gasoline stations are for the internal combustion engine). There are two key barriers to plug-ins: first, the current battery technology is very expensive, adding thousands of dollars to the cost of a plug-in. Next, many well-established sectors must change to accommodate plug-ins. Consumers must learn the pros and cons of a plug-in lifestyle, and a new way of valuing upfront costs against operational savings. Utilities must learn to manage a large and mobile load. Cities, retailers, and other businesses must incorporate a new infrastructure of charge spots. All these players must build a new system of connectivity in order to line up charging times, billing, and consumer preferences.
Earth Day 2011
April 18, 2011 05:55 AM - Andy Soos, ENN
When is Earth Day? In many ways it should be every day but officially it is the anniversary of the first formal celebration on April 22, 1970. An estimated 20 million Americans wearing bell-bottoms and gas masks, gathered to voice their concerns about the deterioration of the environment. Earth Day is celebrated by no one central authority or government. Many different organizations (public, private and individuals) supply personal initiative to the celebration. The closest to a general or national governmental response was the U.S. Environmental Protection Agency on April 16 and 17 on the National Mall. With more than 40 interactive exhibits, kids and adults can have eco-fun with hands on activities, art, music and storytelling with special guests. Special guests include Marcus McNeill from the San Diego Chargers, Madieu Williams from the Minnesota Vikings, and Olympic track star Michael Walton. Visitors learnt how to protect their own health and the environment in which they live.

The U.S. Environmental Protection Agency (EPA) has released action plans to address the potential health risks of methylene diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), and related compounds. Americans may be exposed to these chemicals when they are used in certain applications such as spray foam insulation, sealing concrete or finishing floors. The plans identify a range of actions the agency is considering under the authority of the Toxic Substances Control Act. Spray polyurethane foam (SPF) is a highly-effective and widely used insulation and air sealant material. However, exposures to its key ingredient, isocyanates such as MDI, and other SPF chemicals in vapors, aerosols, and dust during and after installation can cause adverse health effects.
Wolves Taken Off the US Endangered Species List
April 14, 2011 09:22 AM - David A Gabel, ENN
For the first time ever, the US Congress has removed an animal from the Endangered Species List, a process typically done by a federal, non-political, science-based agency. The action by the US Congress sets a new precedent for altering the Endangered Species List based on political influence, enraging environmental groups. The removal would take effect in two western states that have known issues with wolves: Montana and Idaho. Wolves would now be managed by each state’s wildlife agency, inevitably leading to commercial hunting.
The Memory of Alcohol
April 14, 2011 07:49 AM - Andy Soos, ENN
An alcoholic beverage is a drink containing ethanol, commonly known as alcohol. Alcoholic beverages are divided into three general classes: beers, wines, and spirits Drinking alcohol primes certain areas of our brain to learn and remember better, says a new study from the Waggoner Center for Alcohol and Addiction Research at The University of Texas at Austin. The common view that drinking is bad for learning and memory isn’t wrong, says neurobiologist Hitoshi Morikawa, but it highlights only one side of what ethanol consumption does to the brain.
Decline of the Southern Skua in the Falkland Islands
April 13, 2011 09:49 AM - David A Gabel, ENN
The Falkland Islands, a British overseas territory in the South Atlantic Ocean near the coast of South America, is home to several unique indigenous bird species. One of them, Catharacta Antarctica, also known as the Southern Skua or the Falklands Skua, is in serious decline. Over the past five years, their population has gone down almost 50 percent. The exact reasons are unknown, but some experts suspect the decline is due to low breeding success and increased competition for resources. Some fear that the problems with the skua are linked with an unhealthy Patagonian marine ecosystem.
Yellowstone Supervolcano Size
April 13, 2011 08:30 AM - Andy Soos, ENN
University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves. The Yellowstone Caldera is the volcanic caldera located in Yellowstone National Park in the United States, sometimes referred to as the Yellowstone Supervolcano. The caldera is located in the northwest corner of Wyoming, in which the vast majority of the park is contained. The major features of the caldera measure about 34 miles by 45 miles.
Pliocene Hot Age?
April 12, 2011 05:16 PM - Andy Soos, ENN
By studying fossilized mollusks from some 3.5 million years ago, UCLA geoscientists and colleagues have been able to construct an ancient climate record that holds clues about the long-term effects of Earth's current levels of atmospheric carbon dioxide, a key contributor to global climate change. Two novel geochemical techniques used to determine the temperature at which the mollusk shells were formed suggest that summertime Arctic temperatures during the early Pliocene epoch (3.5 million to 4 million years ago) may have been a staggering 18 to 28 degrees Fahrenheit warmer than today. These ancient fossils, harvested from deep within the Arctic Circle, may have once lived in an environment in which the polar ice cap melted completely during the summer months. The Pliocene Epoch is the period in the geologic timescale that extends from 5.3 million to 2.6 million years before the present time.
The Mighty Blueberry
April 12, 2011 09:55 AM - David A Gabel, ENN
Blueberries are incredible plants. They can grow wild practically anywhere in the northeastern United States and Canada, and are quite tasty. Blueberry bushes can cover vast stretches of meadows and become the dominant plant. Amazingly, they thrive after forest fires, even after they burn themselves. To go along with the plant's hardiness and the berries' deliciousness, blueberries offer great health benefits. According to a new study from Texas Woman’s University (TWU) in Denton, TX, blueberries have a positive effect on aging, metabolism, and inhibiting the development of fat cells.
