Mine runoff continues to provide clues to microbial diversification
03-07-2007 · Oak Ridge National Laboratory (ORNL)Pink slime at the surface of water trickling through an old mine in California is proving to be a treasure for researchers in their quest to learn more about how bacterial communities exist in nature. A letter published in today's online edition of Nature shows that it is possible to follow what microorganisms are doing in their natural environment by identifying the range of proteins that they produce. The technique, utilized in a microbial community thriving in battery acid-like streams underground at Richmond Mine near Redding, Calif., combines recently developed ways to sequence microbial genes with methods to identify the range of proteins from specific microbial members.

- Sperm's immune-protection properties could provide link to how cancers spread
12-13-2007 · EurekAlert!
Sugar-based markers on human sperm cells which may prevent them from being attacked by the female immune system could provide a vital clue to how some cancers spread in the human body, according to new research published on Dec. 14, 2007.

- Tumor cell activity may provide clues for treating breast cancer in young women
06-03-2007 · EurekAlert!
When women under 50 develop breast cancer the disease tends to be more aggressive and less responsive to treatment than when it occurs in older women. Researchers at the Duke Institute for Genome Sciences & Policy and the Duke University Comprehensive Cancer Center may have discovered a part of the reason why, and their findings may lead to targeted therapies that can help treat patients more effectively.

- Study finds fecal microbes high in New Orleans sediments following Hurricanes Katrina and Rita
05-03-2007 · EurekAlert!
In a new study documenting the microbial landscape of New Orleans and Lake Pontchartrain in the wake of Hurricanes Katrina and Rita, scientists report that sediments in interior portions of the city appear to be contaminated with fecal microbes, a chronic condition they say persisted in the area before the hurricanes, and that the resulting water quality in the city and in nearshore waters of the lake continues to be impacted by discharges from this contamination.

- Green roofs offer energy savings, storm-water control
11-01-2007 · EurekAlert!
An article in the November 2007 issue of BioScience describes green roofs -- roofs with a vegetated surface and substrate. Although more expensive to construct than a typical roof, a green roof can reduce energy costs during a building's lifetime and control storm-water runoff. Green roofs also provide havens for wildlife. Further research into their ecology and improved cost-benefit models could spur more widespread adoption of the technology.

- Past greenhouse warming events provide clues to what the future may hold
02-15-2008 · EurekAlert!
Scientists studying an extreme period of global warming 55 million years ago are piecing together an increasingly detailed picture of its causes and consequences. Their findings describe what may be the best analog in the geologic record for the global changes likely to result from continued carbon dioxide emissions from human activities.

- Blood protein offers clues to heart attack in seemingly healthy people
07-02-2007 · EurekAlert!
We've all wondered how a seemingly healthy person can actually be at high risk for heart disease or a heart attack. Now researchers have uncovered a new clue to this mystery. The culprit: myeloperoxidase, a protein secreted by white blood cells that both signals inflammation and releases a bleach-like substance that damages the cardiovascular system.
