Latino children who live in areas with higher levels of air pollution have a heightened risk of developing Type 2 diabetes, according to a new USC-led study.

Scientists tracked children’s health and respective levels of residential air pollution for about 3.5 years before associating chronic unhealthy air exposure to a breakdown in beta cells, special pancreatic cells that secrete insulin and maintain the appropriate sugar level in the bloodstream.

A new Duke University study has found high levels of selenium in fish in three North Carolina lakes receiving power plants’ coal ash waste.

“Across the board, we’re seeing elevated selenium levels in fish from lakes affected by coal combustion residual effluents,” said Jessica Brandt, a doctoral student in environmental health at Duke’s Nicholas School of the Environment, who led the study.

Imagine if you could take pollution produced by diesel engines and turn it into a non-carcinogenic substance used in ink, reducing the need for burning fossil fuels.

A study has found that fiscal policies introduced by governments in developing countries can have a significant effect on lowering harmful carbon emissions and help countries with fulfilling their commitments under the UNFCCC Paris Agreement.

The research, led by scientists from the University of Sheffield, found increasing the level below which the ground is saturated with water – known as the water table – in radish fields by 20cm not only reduced soil CO2 emissions, but also improved the growth of crops.

Researchers have developed an infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks in pipelines and at oil and gas facilities. Leaks of methane, the primary component of natural gas, can be costly and dangerous while also contributing to climate change as a greenhouse gas.

Nitrogen deposition caused by human activities can lead to an increased phytoplankton production in boreal lakes. The response of boreal lakes to nitrogen deposition will strongly depend on each lake’s content of organic carbon, which are predicted to increase with future warmer and wetter climate. This according to a thesis at Umeå University.

The worldwide increase of inorganic nitrogen deposition via fossil fuel combustion, fertilization and forestry has been intervening drastically with the Earths’ natural nitrogen cycle. Food webs of boreal lakes, that have historically received little nitrogen deposition until now, are expected to be especially susceptible to increases in inorganic nitrogen availability.

Decades after a uranium mine is shuttered, the radioactive element can still persist in groundwater at the site, despite cleanup efforts.

A recent study led by scientists at the Department of Energy’s SLAC National Accelerator Laboratory helps describe how the contaminant cycles through the environment at former uranium mining sites and why it can be difficult to remove. Contrary to assumptions that have been used for modeling uranium behavior, researchers found the contaminant binds to organic matter in sediments. The findings provide more accurate information for monitoring and remediation at the sites.

The results were published in the Proceedings of the National Academy of Sciences.

In 2014, researchers at SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL) began collaborating with the DOE Office of Legacy Management, which handles contaminated sites associated with the legacy of DOE’s nuclear energy and weapons production activities. Through projects associated with the Uranium Mill Tailings Radiation Control Act, the DOE remediated 22 sites in Colorado, Wyoming and New Mexico where uranium had been extracted and processed during the 1940s to 1970s.

According to a new study published in the journal Proceedings of the National Academy of Sciences, 35% of black carbon in the Russian Arctic originates from residential heating sources, 38% comes from transport, while open fires, power plants, and gas flaring are responsible for only 12%, 9%, and 6% respectively. These estimates confirm previous work for some areas of the European Arctic, but for Siberia, the findings differ from previous research, which had suggested that contribution from gas flaring were much higher.

A new study analyzes the genetic diversity and population structure of the California Ridgway’s rail, Rallus obsoletus, a state and federally-listed endangered bird. The results demonstrate that the so-called “rails” are experiencing negative genetic effects following more than a century of salt marsh habitat loss from agriculture, commercial salt production and urban development.
