... ethnic groups is caused, in part, by an inherited tendency to retain salt. In the December issue of the American Journal of Human Genetics, (available now on-line) the researchers show that the frequency of one version of a gene that plays a crucial role in salt retention correlates with distance from the ...Spatial structure, dispersal, and management of a recovering raptor population

...bB gene has a highly repetitive section that has a tendency to slip when the bacteria copies its DNA prior to cell division," Berg explains. "These slips can introduce extra repeats or delete them, shifting how the gene is translated from DNA to protein in a way that's likely to halt protein synthesis by intr...Hold the stuffing: Low-glycemic diet may help keep weight off
... low-glycemic diet may overcome the body's natural tendency to slow metabolism and turn on hunger cues to "make up" the missing calories. The low-glycemic-load (low-GL) diet reduces carbohydrates that are rapidly digested and that raise blood sugar and insulin to high levels -- such as white bread, refined br......se it shows training can overcome sparrows' innate tendency to start their song with a whistle (represented by A).
