Unihemispheric slow-wave sleep (USWS) is sleep in which one half of an animal's brain is at rest, while the other half remains alert. During USWS, only one eye is closed, allowing the animal to remain alert to activity in its environment. It has been observed in various species of birds, dolphins, seals, lizards, and manatees. This type of sleep probably resulted from environmental factors such as an abundance of predators or the need to continue moving while asleep. Some birds are able to rest both halves of their brains at the same time to remain active for longer periods of time than would be possible with the mental alertness normal sleep allows. In fact, this mode of sleeping is the most common, and terrestrial mammals generally do sleep with both hemispheres at the same time.
This phenomenon has been studied by behavioral neurophysiologists Niles/Niels C. Rattenborg, Steven L. Lima, Charles J. Amlaner and other colleagues of Indiana State University Department of Life Sciences. They have published content in Nature on the subject. USWS is possibly the first animal behavior which uses different regions of the brain to simultaneously control sleep and wakefulness.
How much sleep do you actually need? In a recent story in Time magazine, a 2002 study found that Americans receiving between 6-and-a-half and 7-and-a-half hours of sleep live the longest, and that a higher death risk is associated with people receiving too little or too much sleep. In fact, more than 1-million American adults participated in the study that found sickness is U-shaped, meaning people receiving very short sleep and those receiving very long sleep are linked to more illnesses, and those range from depression to obesity and heart disease. The report also said that people suffering from insomnia should restrict time spent in bed and this treatment is actually more powerful and effective than using prescription sleeping pills.

One employee at Fred Meyer accidentally entered the LP code this spring versus the CD-DVD edition when ordering REM’s latest “Accelerate” album. Boxes of the vinyl disks got shipped to many Fred Meyer locations and some chose to sell the LPs, reporting 20 sales the first day.
