Evidence Emerges of Ancient Lake in California’s Eel River

*Ecological changes from lakebed may have led to two different populations of once-related steelhead trout*

A catastrophic landslide 22,500 years ago dammed the upper reaches of northern California’s Eel River, forming a 30-mile-long lake which has since disappeared. It left a living legacy found today in the genes of the region’s steelhead trout.

Using remote-sensing technology known as airborne Light Detection and Ranging (LiDAR) and hand-held global-positioning-systems (GPS) units, scientists recently found evidence for a late Pleistocene, landslide-dammed lake along the river. (more…)

Rising Air Pollution Worsens Drought, Flooding UMD-Led Study Shows

COLLEGE PARK, Md. – Increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons, says a new study by a University of Maryland-led team of researchers.

More fiber, but not necessarily less fat, good for teen diets

EAST LANSING, Mich. — A diet high in fiber – but not necessarily one low in saturated fat or cholesterol – is tied to a lower risk of heart disease and type-2 diabetes in teenagers, according to new findings from Michigan State University.

A study led by Joseph Carlson of MSU’s Division of Sports and Cardiovascular Nutrition suggests to reduce metabolic syndrome – a collection of risk factors including high blood pressure and a large waistline – it is more important to emphasize diets including fiber-rich, nutrient-dense, plant-based foods than focus on restricting foods high in cholesterol or saturated fat.

New Turkey Feed Helps Bird Producers Gobble Up Profits

New formula reduces feed costs by 10 percent

COLUMBIA, Mo. – As feed prices have risen in recent years, feeding turkeys has become more costly than many producers can bear. Satisfying turkeys’ hunger accounts for 70 percent of the cost of producing turkey meat. Now, a researcher at the University of Missouri has produced a cheaper turkey feed, which could fill turkeys’ tummies and producers’ pockets. (more…)

Berkeley Lab Researchers Create First of Its Kind Gene Map of Sulfate-reducing Bacterium: Work Holds Implications for Future Bioremediation Efforts

Critical genetic secrets of a bacterium that holds potential for removing toxic and radioactive waste from the environment have been revealed in a study by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab). The researchers have provided the first ever map of the genes that determine how these bacteria interact with their surrounding environment.

“Knowing how bacteria respond to environmental changes is crucial to our understanding of how their physiology tracks with consequences that are both good, such as bioremediation, and bad, such as biofouling,” says Aindrila Mukhopadhyay, a chemist with Berkeley Lab’s Physical Biosciences Division, who led this research. “We have reported the first systematic mapping of the genes in a sulfate-reducing bacterium – Desulfovibrio vulgaris – that regulate the mechanisms by which the bacteria perceive and respond to environmental signals.” (more…)
