It's no sweat for salt marsh sparrows to beat the heat if they have a larger bill
Birds use their bills largely to forage and eat, and these behaviors strongly influence the bill's shape and size. But the bill can play an important role in regulating the bird's body temperature by acting as a radiator for excess heat. A team of scientists have found that because of this, high summer temperatures have been a strong influence in determining bill size in some birds, particularly species of sparrows that favor salt marshes.

Kidney dopamine regulates blood pressure, life span
The neurotransmitter dopamine is best known for its roles in the brain -- in signaling pathways that control movement, motivation, reward, learning and memory. Now, Vanderbilt University investigators report in the July Journal of Clinical Investigation that dopamine produced outside the brain -- in the kidneys -- is important for renal function, blood pressure regulation and life span. Their studies suggest that the kidney-specific dopamine system may be a therapeutic target for treating hypertension and kidney diseases. (2011-07-19)
