Nice guys do finish first in lizards' evolutionary race, says MSU professor

A study on side-blotched lizards found that cooperating males pass on their genes through a trait known as the 'greenbeard,' despite personal costs. The researchers identified three throat colors and behaviors that follow 'rock-paper-scissors' cycles, showcasing how cooperation can be beneficial in evolutionary terms.

Diuretic may not be best way to reduce CHF water retention

A new study suggests that lixivaptan, a drug blocking vasopressin, is as effective as diuretics in reducing fluid retention in patients with congestive heart failure while also retaining proper sodium levels. The drug may offer an alternative treatment for heart failure patients and help clarify the role of vasopressin in water retention.
