Researchers Assess Radioactivity Released to the Ocean from the Fukushima Dai-Ichi Nuclear Power Facility

With news this week of additional radioactive leaks from Fukushima nuclear power plants, the impact on the ocean of releases of radioactivity from the plants remains unclear. But a new study by U.S. and Japanese researchers analyzes the levels of radioactivity discharged from the facility in the first four months after the accident and draws some basic conclusions about the history of contaminant releases to the ocean.

Report evaluates amount of carbon absorbed by wetlands, grasslands and forests in the Great Plains region

WASHINGTON, D.C. — The Department of the Interior today released the first in a series of regional studies measuring the amount of carbon stored in U.S. ecosystems. Published by Interior’s U.S. Geological Survey (USGS), the study examines the current and projected future carbon storage in the Great Plains region, as part of a nation-wide assessment. (more…)

UCLA life scientists and colleagues have produced the most comprehensive mathematical model ever devised to track the health of populations exposed to environmental change.

The research, federally funded by the National Science Foundation, is published Dec. 2 in the journal Science.

The team’s groundbreaking integral projection model, or IPM, unites various sub-disciplines of population biology, including population ecology, quantitative genetics, population genetics, and life-span and offspring information, allowing researchers to link many different data sources simultaneously. Scientists can now change just a single variable, like temperature, and see how that affects many factors for a population. (more…)

A Yale University-led research team has found evidence that carbon dioxide levels in Earth’s atmosphere plunged prior to and during the initial icing of Antarctica, about 34 million years ago. The new findings provide further evidence of atmospheric carbon dioxide’s role as a major trigger of global climate change.

“CO2 is tracking global cooling at that time,” said Yale geochemist Mark Pagani, lead author of a paper published online Dec. 1 in the journal Science. “It’s important to demonstrate that there are obvious linkages between CO2 and climate change. It’s one more piece of evidence that CO2 is a primary lever on climate.” (more…)

Petroleum-eating Mushrooms

Take a Petri dish containing crude petroleum and it will release a strong odor distinctive of the toxins that make up the fossil fuel. Sprinkle mushroom spores over the Petri dish and let it sit for two weeks in an incubator, and surprise, the petroleum and its smell will disappear. “The mushrooms consumed the petroleum!” says Mohamed Hijri, a professor of biological sciences and researcher at the University of Montreal’s Institut de recherche en biologie végétale (IRBV).

Minorities Pay More for Water and Sewer

EAST LANSING, Mich. — Racial minorities pay systemically more for basic water and sewer services than white people, according to a study by Michigan State University researchers.

This “structural inequality” is not necessarily a product of racism, argues sociologist Stephen Gasteyer, but rather the result of whites fleeing urban areas and leaving minority residents to bear the costs of maintaining aging water and sewer infrastructure. (more…)
