Psychologists have announced the results of a two-year study into dream control. The experiment shows that it is now possible for people to create their perfect dream, and so wake up feeling especially happy and refreshed. Researchers also discovered that people's dreams were especially bizarre around the time of a full moon.

In many group-living species, high-rank individuals bully their group-mates to get what they want, but their contribution is key to success in conflict with other groups, according to a study that sheds new light on the evolutionary roots of cooperation and group conflict. In a series of mathematical models, researchers uncovered a mechanism for explaining how between-group conflict influences within-group cooperation and how genes for this behavior might be maintained in the population by natural selection.

A new generation supercomputer, capable of more than one million billion calculations a second, is to be inaugurated. ARCHER will help researchers carry out sophisticated, complex calculations in diverse areas such as simulating Earth's climate, calculating the airflow around aircraft, and designing novel materials.

A mathematical model can predict with more than 90 percent accuracy the blood glucose levels of individuals with type 1 diabetes up to 30 minutes in advance of imminent changes in their levels -- plenty of time to take preventative action. A person's blood glucose levels fluctuate in response to his or her insulin dose, meal intake, physical activity and emotional state. How great these fluctuations are depends on the individual, explain the researchers.
