...erly polarize," Poulton said. "We proved this by observing that mutated forms of genes in the EGFR pathway of cells surrounding the oocyte led to abnormally high levels of Dystroglycan protein, which in turn disrupted oocyte polarity. However, even with the mutated EGFR pathway gene, we were able to restore ...Tight-knit family: Even microbes favor their own kin

By observing the birds closely and performing simple playback and feeding experiments, the biologists found that babbler adults use a special "purr" call to recruit inexperienced fledglings to rich, divisible food sources (adults responding to the calls often met...Census of Marine Life US National Committee hosts 2006 Marine Biodiversity Workshop
