| Circadian Clock May Be Critical For Remembering What You Learn, Researchers Say Posted: 09 Oct 2008 10:00 AM CDT The circadian rhythm that quietly pulses inside us all, guiding our daily cycle from sleep to wakefulness and back to sleep again, may be doing much more than just that simple metronomic task, according to researchers. Working with Siberian hamsters, biologist Norman Ruby has shown that having a functioning circadian system is critical to the hamsters' ability to remember what they have learned. Without it, he said, "They can't remember anything." |
| The Pepperoni Pizza Hypothesis Posted: 09 Oct 2008 10:00 AM CDT What's the worst that could happen after eating a slice of pepperoni pizza? A little heartburn, for most people. But for up to a million women in the US who have a chronic bladder condition, enjoying that piece of pizza and other foods can cause intense pelvic pain and an urgent need to frequently urinate. Researchers believe a surprise culprit is causing the pain: the colon. This concept opens up new treatment options for this debilitating condition. |
