The dead zone off the coasts of Louisiana and Texas is nearly the size of Connecticut and much larger than federal researchers had predicted earlier this year, according to a new survey.
The dead zone off the coasts of Louisiana and Texas should be considerably smaller than usual this year - about the size of Rhode Island, rather than larger than Jamaica, researchers say.
Expectant mothers at risk of premature birth may want to consider drinking pomegranate juice to help their babies resist brain injuries from low oxygen and reduced blood flow, a new mouse study from Washington University School of Medicine in St. Louis suggests.
Through mid-July, scientists from NOAA's National Coast Data Development Center and the agency's Fisheries Service at Stennis Space Center will look at data about dissolved oxygen from the "dead zone" areas in the Gulf of Mexico.
Three studies in the June issue of Cell Metabolism offer additional insight into how the cells of mammals sense oxygen. Oxygen plays a central role in fueling cells, and oxygen deficiency underlies many disease conditions, including heart attack, stroke, inflammation, and cancer. The findings should help to resolve a long-standing controversy over the identity of mammalian oxygen sensors, according to the researchers.
Researchers have produced the strongest evidence yet that mitochondria â€” the organelles that generate energy to power the cell â€” also monitor oxygen concentration in the cell. If oxygen slips below a critical threshold, the mitochondrial â€œsensorâ€ triggers protective responses to promote survival.
Who would have thought that melting snow cover in the Himalayan Mountains could alter the ocean food chain over a thousand miles away? Well, that's just what's happening, according to a NASA-funded study appearing in this week's Science magazine.
