At least four children died after rabid vampire bats attacked Awajun indigenous communities in a remote part of Peru, reports the BBC.
Peru's health ministry sent emergency teams to vaccinate villagers in the affected area of Urakusa, which is located close to the border with Ecuador. More than 500 people were reportedly bitten by vampire bats. Most have now been vaccinated.

Not everyone can drive to work in their own vehicle. Planners must find ways to blend individual vehicles with hte needs of mass transportation. Building train stations or subways is highly capital intensive and involves years of construction and related dealys due ot construction. Adding buses adds to traffic. Furthermore mass transist needs to be safe, clean and inexpensive. The straddling bus, first exhibited on the 13th Beijing International High-tech Expo in May this year, maybe one answer. In the near future, the model is to be put into pilot use in Beijing’s Mentougou District.

New research published by University of Washington seismologists reports the results of monitoring they have been recording of a slow-moving and unfelt seismic event under the Olympic Peninsula. It promises to be the best-documented such event in the eight years since the regularly occurring phenomena were first discovered.
"It appears to be right on time," Steve Malone, a UW Earth and space sciences professor, said of the most recent of what are termed episodic tremor-and-slip, or slow-slip, events. "The first signals were mostly fairly weak, but they were easily detected."
The first ground motion associated with the event was recorded very early Sunday morning in an area north of Olympia and west of Tacoma. By Monday afternoon the signals were substantially stronger. If the event behaves like past occurrences, the source of the rumbling will move north through the Olympic Peninsula during the next week before crossing the Strait of Juan de Fuca to Canada's Vancouver Island

A massive reduction in grasslands and the spread of forests may have been the primary cause of the decline of mammals such as the woolly mammoth, woolly rhino and cave lion, according to Durham University scientists.
The findings of the new study challenge the theory that human beings were the primary cause of the extinction of mammals through hunting, competition for land and increased pressure on habitats.
The research is part of the most comprehensive study to date of Northern Hemisphere climate and vegetation during and after the height of the last Ice Age, 21,000 years ago.

Waterborne chemicals leached from plastics and detergents, including bisphenol A (BPA), may have contributed to significant lobster die-offs in the waters of Long Island Sound over the last decade, researchers say. As many as half of the lobsters tested in areas where lobster populations have plunged showed high levels of alkylphenols, a group of chemicals derived from detergents, paints, and plastics, according to researchers at the University of Connecticut.

Dead zones are hypoxic (low-oxygen) areas in the world's oceans, the observed incidences of which have been increasing since oceanographers began noting them in the 1970s. These occur near inhabited coastlines, where aquatic life is most concentrated. Every summer for the past nine years, water with lethally low concentrations of oxygen has appeared off the Oregon coast. The cause is not clear and it does not fit the pattern of several other dead zones associated with man made run off issues. Some other causes have been recently implicated in a research study by Oregon State University.

In a bold effort to save one of the world’s rarest amphibians from extinction, one hundred Kihansi spray toads have been flown home to Tanzania after being painstakingly reared at the Bronx Zoo and The Toledo Zoo working in close partnership with the Tanzanian government and the World Bank.
The toads now reside at a new, state-of the-art propagation center in Dar es Salaam, Tanzania’s commercial capitol, with the eventual goal of reintroducing the tiny amphibians into their former habitat.
"On behalf of the Government of the United Republic of Tanzania, we are very grateful to the Bronx Zoo and The Toledo Zoo for taking care of these precious toads (KST) for ten years, and now they have safely arrived home via KLM flight and all 100 toads are cheerful as witnessed by our Tanzanian trained KST keepers at the facility at UDSM Zoology Department. We are very optimistic that they will acclimatize soon and be taken to their homeland in Kihansi Gorge in the near future," said Anna Maembe on behalf of the Government of Tanzania.

ENN is proud to be a media sponsor of this important event hosted by our Affiliate, Justmeans.
The rapid adoption of social media and the shift within corporations to measure and manage social and environmental impact is fundamentally changing the way companies engage with their stakeholders. Companies will need to work much more closely with stakeholders in order to navigate these two trends. Despite the complexities of this new landscape, a wide variety of best practices are emerging to aid organizations.
A select group of corporate executives, social entrepreneurs, and digital gurus will meet to discuss emerging best practices in using social media to create positive social change at the 2010 Social Media, Technology, and Change conference, to be held on November 1st, in New York City. Topics to be discussed include:

Commercial fishermen can now trawl Louisiana's waters for white shrimp as the season opened on Monday, but questions linger about the effects BP Plc's Gulf of Mexico oil spill will have on the harvest.
Some state waters have been open for brown shrimping since the well ruptured on April 20, but the overall catch has been down from previous years partly because a number of boats are signed up with BP's oil spill clean-up program.
The plump, sweet white shrimp are typically larger than brown shrimp and more desired by chefs. The U.S. government has said that seafood pulled from the areas of the Gulf of Mexico that is open to fishing is safe to eat despite all the oil that gushed into the ocean.
More than a fifth of federal waters in the Gulf remain closed due to fear of oil contaminating the seafood.

Ocean acidification is the name given to the ongoing decrease in the pH of the Earth's oceans, caused by their uptake of atmospheric carbon dioxide. Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.18 to 8.1. PH is a measure of the acidity or basicity of a solution. It approximates but is not equal to concentration of hydrogen ions expressed on a logarithmic scale. A low pH indicates a high concentration of hydrogen ions, while a high pH indicates a low concentration. A strong acid would be less than 1 on this scale. A recent study indicates the relative impact on future ocean acidification of different aspects of global climate change mitigation policies such as the year that global emissions peak.

The LEED program — Leadership in Energy and Environmental Design — is playing an increasingly important role in the drive to make buildings in the United States greener and more energy efficient. LEED is now the most prominent and widely adopted green building certification program in the country, with architects and developers striving to earn LEED’s coveted platinum or gold rating, and an increasing number of local, state, and federal regulations beginning to incorporate LEED standards into official building codes.
But LEED — sponsored by the U.S. Green Building Council, an industry group — has a glaring and little-known drawback: It places scant emphasis on factors relating to human health, even as the largely unregulated use of potentially toxic building materials continues to expand. One of LEED's major accomplishments — saving energy by making buildings more airtight — has had the paradoxical effect of more effectively trapping the gases emitted by the unprecedented number of chemicals used in today’s building materials and furnishings.

An iceberg is a large piece of ice formed from freshwater that has broken off from a glacier or ice shelf and is floating in open water. It may subsequently become frozen into pack ice. Alternatively, it may come to rest on the seabed in shallower water, causing ice gouging in the land underneath or becoming an ice island. Because the density of pure ice is less than sea water an iceberg will float in sea water with about one-ninth of the volume of an iceberg above water. The shape of the underwater portion can be difficult to judge by looking at the portion above the surface. This has led to the expression "tip of the iceberg", for a problem or difficulty that is only a small manifestation of a larger problem.

It'll take years to fully know the effects of the BP oil spill on wildlife in the Gulf of Mexico. One thing we do know now is what that wildlife was like before the 206 million gallons of oil spewed into the water. For that knowledge, we have the Smithsonian Institution to thank.
The Smithsonian Institution's Museum Support Center is an anonymous beige warehouse complex just outside Washington, D.C. It doesn't look like anything special until you get inside.
These buildings house all the things that don't fit into the museums on the National Mall, in endless rows of jars and bottles and boxes. Among them is the world's largest collection of invertebrates from the Gulf of Mexico, all floating in 150-proof alcohol. It's a pretty comprehensive snapshot of life before the spill.

Environmentalists are dismayed at plans by the Tanzanian government to build a major commercial highway through Serengeti National Park
The Tanzanian President has vowed to go ahead with controversial plans to construct a major road through the Serengeti, despite fierce opposition from environmentalists and the tourism industry.
The 480-kilometre road will link the Lake Victoria area with eastern Tanzania and, according to the Tanzanian government, bring essential economic development to the region - linking remote communities to the major road network, allowing transport of people and goods and connecting farmers with markets.

Fears that fires scorching forests polluted by Chernobyl fallout may propel dangerous amounts of radioactivity into the air are overblown, scientists say, and the actual health risks are very small.
Even firefighters tackling the blazes, which officials say have hit forests in Russia's Bryansk region tainted by radioactive dust from the 1986 Chernobyl reactor disaster, are unlikely to run any added nuclear contamination risks.
The amount of radiation in smoke would be only a fraction of the original fallout, they say.
"Of the total radioactivity in the area, much less than one percent of it will be remobilized," said Jim Smith, an expert on Chernobyl and a specialist in Earth and Environmental Sciences at Britain's University of Portsmouth.
Radioactive contamination in the area has substantially diminished in the almost two and a half decades since explosions at Chernobyl's reactor No. 4 caused the world's worst civil nuclear disaster on April 26, 1986.

Decades ago the only type of car was the internal combustion (gasoline)type. Other varieties have arrived such as Hybrid and electric. With the new choices are other decisions such as which one reduces most the carbon footprint (or is the most green)and which one is the most cost effective. No more is "the miles per gallon" a standard that can be applied across the board as a specification.

Our cities play a vital role in the quest to achieve global ecological sustainability. They are the largest contributors to greenhouse gases and climate change. However, if we can achieve sustainable construction and use of urban infrastructure, our cities could become a critical leverage point in global efforts to drastically reduce emissions and avoid the social and economic costs associated with climate change, as well as enhance energy security and resilience in the face of high fossil energy prices.
