What's the number one reason for locating your headquarters (like the storied Lloyd's shipping is doing now) to asia? Time Zone. Still can't beat a morning's work--after a good night's sleep.

When Jones, the nighttime trucker based in South Amboy, New Jersey, has a stretch of eight hours in the daytime to sleep, his body won't allow him.
"I will wake up after four hours," he said. "I'm wide awake. I can't go back to sleep. That has to do with the sun is out and the birds are singing." |

Scientists isolates the gene responsible for regulating sleep:
--------------------------------------------------------------------------------
Scientists find rare gene behind short sleepers
Yahoo!
By LAURAN NEERGAARD, AP Medical Writer Lauran Neergaard, Ap Medical Writer – 2 hrs 31 mins ago
WASHINGTON – Scientists have discovered a gene that helps a mother and daughter stay alert on about six hours sleep a night, two hours less than the rest of their family needs.
It's believed to be a very rare mutation, not an excuse for the rest of us who stay up too late. But the finding, published in Friday's edition of the journal Science, offers a new lead to study how sleep affects health.
The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little increases the risk of health problems, including memory impairment and a weakened immune system. A major 2006 study estimated that as many as 30 million Americans suffer chronic insomnia, and millions more have other sleep disorders, including sleep apnea.
University of California, San Francisco, researchers have long hunted genes related to how and when people sleep. In 2001, they discovered a mutation that puts its carriers' sleep patterns out of whack: These people regularly go to bed around 7:30 p.m. and wake around 3:30 a.m.
Now the same team has found a gene involved in regulating length of sleep. In one family, the 69-year-old mother and her 44-year-old daughter typically go to bed around 10 p.m., and Mom rises around 4 and her daughter around 4:30, with no apparent ill effects. The rest of the family has typical sleep patterns.
Blood tests showed the women harbored a mutation in a gene named DEC2 that's involved in regulation of circadian rhythms, the body's clock. A check of more than 250 stored DNA samples didn't find another carrier.
Then lead researcher Ying-Hui Fu, a neurology professor, and colleagues bred mice and fruit flies that carried the mutation. Sure enough, the flies' activity and brain-wave measurements on the mice showed those with the mutation slept less — and the mice needed less time to recover from sleep deprivation.
The result: A model that "provides a unique opportunity" to study the effects of different amounts of sleep, Fu concluded. |

The need for sleep is still a mystery to us at this point. But many scientists are diligently working on the "problem."

| Quote: | Even a 90-minute nap can significantly improve our ability to master new motor skills and strengthen our memories of what we learn, researchers at the University of Haifa in Israel reported last month in Nature Neuroscience. "Napping is as effective as a night's sleep," said psychologist Sara Mednick at the University of California in San Diego.
.....
Sleep is controlled partly by our genes. The difference between those of us who naturally wake at dawn and night owls who are wide-eyed at midnight may be partly due to variations in a gene named Period3, which affects our biological clock. Variations in that gene also make some people especially sensitive to sleep deprivation, scientists at the U.K.'s University of Surrey recently reported. |
