A study in the Nov. 1 issue of the journal Sleep is the first demonstration of a specific neurochemical abnormality in adults with primary insomnia, providing greater insight to the limited understanding of the condition's pathology. 

Results indicate that gamma-aminobutyric acid (GABA), the most common inhibitory transmitter in the brain, is reduced by nearly 30 percent in individuals who have been suffering from primary insomnia for more than six months. These findings suggest that primary insomnia is a manifestation of a neurobiological state of hyperarousal, which is present during both waking and sleep at physiological and cognitive levels.

Children and teens in such conditions will not grow as tall or big as their healthy counterparts who were able to allocate more of their energy stores directly to growth.

In 2006, Al Gore alleged that Hurricane Katrina had been caused, or at least made worse, by global warming.    Bill Gray, one of the foremost hurricane experts in the world, disagreed.    Who was right?   Weather, and especially hurricanes, are not among things that are easy to predict but global warming is certain to have an impact.   What impact is all depending on what you want to believe.

Don't start feeling too secure about the so-called McEliece encryption system - a candidate for the security of Internet traffic in the age of the quantum computer, the predicted superpowerful computer of the future.
