Mounting tension in the Himalaya
In the days following the April 2015 earthquake in Nepal, afterslip produced little surface evidence of continued movement. That meant only one of two things could be happening: either the part of the fault that hadn't moved was experiencing a slow-slip event, a slow-motion earthquake, or it remained completely locked, accumulating further strain in that segment of the fault. A new research paper finds it is likely the latter. (2016-06-13)

NOAA, USGS, partners predict an average 'dead zone' for Gulf of Mexico
Scientists forecast that this year's Gulf of Mexico dead zone -- an area of low to no oxygen that can kill fish and marine life -- will be approximately 5,898 square miles or about the size of Connecticut, the same range as it has averaged over the last several years. (2016-06-10)

A conservative environment makes conservatives happier
Various psychological studies have suggested that conservatives are happier than liberals. However, these studies tend to focus exclusively on the United States. Does a correlation between conservatism and life satisfaction also exist in Europe? Two recent studies suggest that the life satisfaction of conservatives largely depends on the overall political climate and on social belonging. (2016-06-08)

Pharmaceuticals in streams may come from multiple sources
Pharmaceuticals in surface water such as lakes and streams are a growing concern. They can cause developmental and other health issues in aquatic life. Scientists have largely considered treated wastewater that's released into the environment as the main source.

When it comes to making patients safer, is a hospital's 'safety culture' that important?
If you work in a hospital these days, you've probably gotten the invitation: Take a survey about how well you, your team and your hospital do at protecting patients from harm, and how empowered you feel to do the right thing. Together, the results provide a hospital's 'patient safety culture' score. But a new study questions whether such surveys actually measure how well a hospital is doing at keeping patients safe. (2016-06-03)
