In his hotly anticipated announcement Wednesday, President Bush ordered NASA scientists to plan for a manned "foothold on the moon." They might look through their old filing cabinets to start, because the U.S. government and its contractors have been planning lunar colonies since long before Neil Armstrong took his one giant leap for mankind in 1969. Who knows... Maybe it'll be the next austrailia. Moon Base: NASA's Recurring Dream |

Brain reverberations during sleep |

In this study, Ribeiro et al. demonstrate that long-lasting neuronal reverberation following novel waking experiences can occur in several forebrain sites and is strongly enhanced during slow-wave sleep. Because neuronal reverberations are sustained for long periods, this may support a mechanism to recall and amplify memories until they are effectively stored. On the basis of differences observed between REM and slow-wave sleep in this and previous studies, the authors propose that the two phases of sleep play separate and complementary roles in memory consolidation. Thus, the two stages of sleep give the brain a chance to process the novel events of the day in peace. ### PLEASE MENTION PLoS BIOLOGY (www.plosbiology.org) AS THE SOURCE FOR THESE ARTICLES.

One of the most important principles of physics, that disorder, or entropy, always increases, has been shown to be untrue. "Scientists at the Australian National University (ANU) have carried out an experiment involving lasers and microscopic beads that disobeys the so-called Second Law of Thermodynamics, something many scientists had considered impossible."

"Monkeys can manage mathematics. Dolphins can be decisive. But US psychologists have broken new ground in the animal intelligence challenge. They have proved that animals are also smart enough to join the "don't-knows". It means that animals, like humans, may be capable not just of thinking, but of thinking about thinking, of knowing that they don't know. Psychologists call this "metacognition", evidence of sophisticated cognitive self-awareness. Ordinary mortals know it as "dithering"." Animals 'can think about thought' |
