Low-Level Radiation Less Harmful to Health Than Other Lifestyle Risks
September 13, 2017 11:02 AM - University of Oxford

Human populations have always been exposed to ionizing radiation, and more so in modern life due to its use in medicine, industry and the armed forces. Whilst the risks to human health from medium and high-level radiation are relatively well-understood, the risks at lower levels are less clear.  Mixed messages about the safety of low doses of radiation from different sources have created confusion for the public and for policy makers.

High-resolution modeling assesses impact of cities on river ecosystems
August 23, 2017 05:29 PM - DOE / Oak Ridge National Laboratory

New mapping methods developed by researchers at the Department of Energy’s Oak Ridge National Laboratory can help urban planners minimize the environmental impacts of cities’ water and energy demands on surrounding stream ecologies.

In an analysis published in Proceedings of the National Academy of Sciences, an ORNL-led team used high-resolution geospatial modeling to quantify the effects of land, energy, and water infrastructures on the nation’s rivers and streams.

Want To Slow Global Warming? Researchers Look To Family Planning

Tori Whitley, NPR

We've all heard of ways to reduce our carbon footprint: biking to work, eating less meat, recycling.

But there's another way to help the climate. A recent study from Lund University in Sweden shows that the biggest way to reduce climate change is to have fewer children.

"I knew this was a sensitive topic to bring up," says study co-author Kimberly Nicholas on NPR's Morning Edition. "Certainly it's not my place as a scientist to dictate choices for other people. But I do think it is my place to do the analysis and report it fairly."

The study concludes that four high-impact ways to reduce CO2 gas emissions include having fewer children, living without a car, avoiding airplane travel and eating a vegetarian diet.
