In the Room of DOOM (Dissolved Oxygen Oyster Mortality), oyster tanks mimic the day-night oxygen swings that oysters experience in shallow Bay waters.
In shallow waters around the world, where nutrient pollution runs high, oxygen levels can plummet to nearly zero at night. Oysters living in these zones are far more likely to pick up the lethal Dermo disease, a team of scientists from the Smithsonian Environmental Research Center discovered. Their findings were published Wednesday in the journal PLOS ONE.

Forest managers must balance concerns for wildlife habitat with reducing the chance for damaging wildfires.
Healthy forest ecosystems need dead wood to provide important habitat for birds and mammals, but there can be too much of a good thing when dead wood fuels severe wildfires. A scientist with the U.S. Forest Service's Pacific Southwest Research Station (PSW) compared historic and recent data from a forest in California's central Sierra Nevada region to determine how logging and fire exclusion have changed the amounts and sizes of dead wood over time. Results were recently published in Forest Ecology and Management.

Physicians at Henry Ford Hospital successfully suctioned a cancerous tumor from a major vein in a patient with metastatic kidney cancer, clearing the way for him to undergo a minimally-invasive kidney removal. This allowed him to participate in a clinical trial using genetic material from his tumor to produce a vaccine to help fight his metastatic disease.
