Bacteria control levels of dangerous pollutant in seabirds

Despite ongoing global pollution, researchers have discovered that levels of mercury in seabirds off the coast of B.C. have remained relatively stable over the past 50 years. Surprisingly, mercury in seabirds is now actually slightly lower. This might appear to be good news, but unfortunately it is due to a decline in fish stocks near the surface which has forced seabirds to change their diet, and in the process to feed in areas low in bacteria (known as sulfate-reducing bacteria) which act to control the levels of mercury in their bodies.

Outdoor recreation in protected areas negatively impacts wildlife

It's a good thing to explore the great outdoors. But a new study led by Colorado State University and the Wildlife Conservation Society found that recreation activities in protected areas are impacting wildlife. More often than not, the impact appears in negative ways.

NASA sees some strength in Tropical Cyclone Vardah’s remnants

After moving into the very warm waters of the southeastern Arabian Sea the remnants of Tropical Cyclone Vardah seemed to have regained some life. Both NASA's Aqua satellite and the Global Precipitation Measurement mission or GPM core satellite saw some strong storms develop in the remnant low pressure area.
