Imagine having a daylong Thanksgiving feast every day for a month, then, only pauper’s rations the rest of the year.

University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaska’s Chignik Lake watershed.

Organs such as the stomach and intestines in the Dolly Varden doubled to quadrupled in size when eggs from spawning sockeye salmon became available each August, the researchers found. They were like vacuums sucking up the eggs and nipping at the flesh of spawned-out salmon carcasses. (more…)

A large pad of fat cells that extends from the stomach and covers the intestines provides nutrients that promote the spread and growth of ovarian cancer, reports a University of Chicago-based research team in the journal Nature Medicine, published online Oct. 30.

Ovarian cancer, the fifth-leading cause of cancer deaths in women, tends to spread within the abdominal cavity as opposed to distant organs. In 80 percent of women, by the time ovarian cancer is diagnosed, it has spread to the pad of fat cells, called the omentum. Often, cancer growth in the omentum exceeds the growth of the original ovarian cancer. (more…)
