Mercury Persists in Fish in Many Parts of US
August 20, 2009 06:39 AM - Roger Greenway, ENN

The U.S. Geological Survey released a study that showed mercury contamination in every fish sampled in 291 streams across the country. The work was part of the National Water-Quality Assessment Program (NAWQA) which provides an understanding of water-quality conditions such as whether conditions are getting better or worse over time and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis.

Not from My Back Yard? Homes Pollute
August 19, 2009 11:55 AM - Eurekalert

They say there's no place like home. But scientists are reporting some unsettling news about homes in the residential areas of California. The typical house there — and probably elsewhere in the country — is an alarming and probably underestimated source of water pollution, according to a new study reported today at the 238th National Meeting of the American Chemical Society.

The Asian Clams of Lake Tahoe are getting TOO comfortable!
August 19, 2009 08:13 AM - Amy Littlefield, Los Angeles Times

The population of the small coffee-colored Asian clams has soared in the southeast portion of the lake, threatening to hog food sources and excrete nutrients that foster algae growth, according to an annual Lake Tahoe report by UC Davis researchers.

No Matter How Well You Model it, Humans are to Blame
August 18, 2009 06:28 AM - R. Greenway, ENN

New research appearing in the online issue of the Proceedings of the U.S. National Academy of Sciences, Lawrence Livermore National Laboratory scientists and a group of international researchers found that model quality does not affect the ability to identify human effects on atmospheric water vapor.

Do Phosphate Oridnances Make a Difference?

August 15, 2009 07:47 AM - R. Greenway, ENN

The Earth's oceans were the warmest ever this July, according to a study released by the National Oceanic and Atmospheric Administration yesterday. The planet's ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA's National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.

Nigeria to roll out fungus-resistant soybean crops
August 12, 2009 10:22 AM - Semiu Babalola, SciDevNet

A variety of soybean resistant to a devastating Asian rust will soon be widely available in West and Central Africa. The rust, a fungal disease that entered Africa in 1996, can wipe out 80 per cent of infected crops.

In Indonesia Development of Cepu Oil Field Begins
August 10, 2009 06:34 AM - Ed Davies, Reuters

In Bojonegoro, Indonesia, development of a large oil field is likely to get the economy pumping. Oil production could start to flow from the huge Cepu field straddling East and Central Java later this month and eventually add millions of dollars to the coffers of local governments, as well as an influx of workers and a wave of new expectations.

Do Clouds Come From Outer Space?
August 9, 2009 10:21 AM - Phil Berardelli, Science

Most of Earth's clouds get their start in deep space. That's the surprising conclusion from a team of researchers who argue that interstellar cosmic rays collide with water molecules in our atmosphere to form overcast skies.

Alaskan Glaciers REALLY are Shrinking
August 8, 2009 10:00 AM - Thomas Schueneman, Global Warming is Real

"Fifty years of U.S. Geological Survey (USGS) research on glacier change shows recent dramatic shrinkage of glaciers in three climatic regions of the United States. These long periods of record provide clues to the climate shifts that may be driving glacier change."
