Puget Sound’s Waters Come from Deep Canyon

April 15, 2014 7:00 am | by Univ. of Washington | News | Comments

The headwaters for Puget Sound’s famously rich waters lie far below the surface, in a submarine canyon that draws nutrient-rich water up from the deep ocean. New measurements may explain how the Pacific Northwest’s inland waters are able to support so many shellfish, salmon runs and even the occasional pod of whales.

Geneticist Outlines Plan to Save Gooseberry

April 10, 2014 12:00 pm | by Florida International Univ. | News | Comments

The Miccosukee gooseberry is on the verge of extinction, but a geneticist believes genetic variation is the key to its survival. The plant, which has been listed as a federally threatened species for nearly three decades, is found in only two counties in the U.S.

Study Tests Theory That Life Originated at Deep Sea Vents

April 10, 2014 7:00 am | by Woods Hole Oceanographic Institution | News | Comments

One theory about the origin of life is that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research has found that it may not have been as easy as previously assumed. Instead, the finds could provide a focus for the search for life on other planets.
