Scientists have discovered a new mechanism in the core gears of the circadian clock. They found the loss of a certain gene, dubbed "twenty-four," messes up the rhythm of the common fruit fly's sleep-wake cycle, making it harder for the flies to awaken. The circadian clock drives, among other things, when an organism wakes up and when it sleeps. While the study was done using Drosophila melanogaster, the findings have implications for humans.
NASHVILLE, Tenn. – To develop correctly, baby hearts need rhythm...even before they have blood to pump. "We have discovered that mechanical forces are important when making baby hearts," said Mary Kathryn Sewell-Loftin, a Vanderbilt... Read Post

You may never hear fruit flies snore, but rest assured that when you're asleep, they are too. Scientists have shown that sleep/wake cycles of fruit flies and vertebrates are regulated by some of the same "cellular machinery" as huma... Read Post
