...in. Gillespie concludes that there are fundamental similarities between the largely ecological processes that govern the formation of communities on a continent and evolutionary process that dominate community formation in the Hawaiian Islands. "This study suggests that the process of community assembly - the way...Monkey talk, human speech share left-brain processing
...alized for vocalizations only, it bears intriguing similarities to human language," noted Mishkin. "Assuming this is an adaptive mechanism, it suggests that vocalizations can be deciphered better if they are processed by only one temporal pole rather than by both." Scientists have known for years that the human ...New evidence points to pollution as main cause of much coral reef destruction
... they attributed to groundwater seepage because of similarities between the chemical signature of nitrogen at the site and from groundwater samples taken from deep inside a submerged cave on the island. Study results supported Lapointe's past research that revealed a critical threshold for nitrogen of about 14 p...Equine cloning's triple play sheds light on calcium, cell signaling, human disease
... to embryonic development. "There are electrifying similarities between cancer metastasis and embryo division," said Woods. Woods' collaborators agreed to try stimulating embryonic development by increasing calcium concentrations in the surrounding medium.

...olicies, and farm sizes, the maps revealed several similarities among the sites where wolves had preyed on cattle in the past. Each town in the two states was assigned a color-code ranging from red (highest risk) to blue (lowest risk). Low risk townships included those with lots of cropland, wetlands and open ...Freeze-dried sperm can fertilize rabbit oocytes
...aki University---note that rabbit sperm share many similarities with human sperm, so their results suggest that the freeze-drying technique could be used to preserve sperm from humans and many other animal species. Previously, only freeze-dried sperm from mice had been shown to support embryo development. Mouse ...Genome of first fungal pathogen unveiled
...e, the researchers said. "We expect many similarities in function among all types of fungal pathogens -- whether they infect plants or humans," said Dietrich, first author of the study. "Understanding one will provide insight into fungal pathogens in general in terms of the forces that drive them." ...Crucial brain development gene identified

...ated came when the researchers observed intriguing similarities in the blood vessel defects in the two disorders in mice lacking the responsible genes. These vessel pathologies occurred in both the eye and the inner ear. "While there was a clinical similarity, the two diseases were far from identical, because FEV...Gene chips help gauge chemotherapy's effectiveness in adult leukemia patients
