AGU journal highlights -- Dec. 31, 2008

Scientists analyzed East/Japan Sea CO2 uptake, finding a surprising drop in recent years. Simulations also suggest large raindrops favor tornado formation. Remotely sensed dune celerity revealed the world's fastest moving dunes, while Martian craters indicate hidden ice deposits.

Dormant cancer cells rely on cellular self-cannibalization to survive

Researchers at the University of Texas M. D. Anderson Cancer Center discovered that a tumor-suppressing gene called ARHI acts as a switch for autophagy in ovarian cancer cells, allowing dormant cells to survive by avoiding starvation. Blocking this autophagic pathway could provide a novel strategy for eliminating dormant ovarian cancer...

Genetic variation may lead to early cardiovascular disease

Researchers at Duke University Medical Center have found a genetic variation in the neuropeptide Y gene that increases susceptibility to early coronary artery disease. The study found six related variations in the gene associated with transmission from generation to generation and association across a population of patients.
