    We meet people in our working lives who can play both the roles of "night owl" and "early bird", go to bed late and get up early, but be energetic all day long. These "short sleepers" are enviable, but we can't emulate them. What makes them so "super-energy"? A new US study has found the key - a genetic mutation in a receptor called NPSR1. The mutation plays an important role in human sleep science, and its introduction into mice can reduce sleep without showing signs of lack of sleep and impaired memory formation, the researchers said in a paper published in the journal Science Translational Medicine on June 16.
    sleep is vital to human health, scientists know little about how to regulate the timing and quality of sleep. The average person needs at least seven hours of sleep a night to get enough energy the next day, and a long sleep of less than six hours can lead to memory loss and increase the risk of obesity, heart disease and stroke. But for "short sleepers", 6 hours of sleep is enough, even if only 4-6 hours a day, will still live dragons and tigers.
    To understand the genetic secrets of "short sleepers," researchers at the University of California, San Francisco and the University of Utah worked together to sequence the genes of two members of a family of "short sleepers" and found mutations in a gene in their body called NPSR1. The researchers introduced the mutation into mice and found that they were more active and sleep-deprived than their wild counterparts. What's more, these mutant mice were well-recovering, and although they had less sleep and more sleep stress, their memory tests were as good as those in wild mice. In addition, mutant mice showed some biological differences because their neurons were extremely sensitive to the neuropeptide NPS that interacts with NPSR1.
    researchers say the findings highlight the importance of NPSR1 subjects in human sleep biology and illustrate the relationship between sleep regulation and memory consolidation. They also stress that improving sleep efficiency can benefit the general population and patients with sleep disorders, such as insomnia, but the role of NPSR1 needs to be better informed before new treatments for sleep problems can be developed.
