Research suggests strong Indian crust thrust beneath the Tibetan Plateau
— 9 Apr 2011 | Geology and palaeontologyFor many years, most scientists studying Tibet have thought that a very hot and very weak lower and middle crust underlies its plateau, flowing like a fluid. Now, a team of researchers at the California Institute of Technology is questioning this long-held belief and proposing that an entirely different mechanism is at play…
How materialistic advertising messages negatively shape the female body image
— 6 Apr 2011 | HealthPsychological research has consistently shown that women feel unhappy with their body after looking at images of thin, idealised models, which are typically represented in the media. However, today's consumer culture and media promote not only the ideal of perfect beauty, but also that of the material affluent lifestyle, both of which are commonly depicted together, and highlight the benefits of beauty and of owning material goods to one's personal success and fame. A new study from the British Journal of Social Psychology is the first to examine the impact of materialistic messages and values - the desire for financial success and an affluent lifestyle on women's feelings about their own body…

Research discovers how marijuana affects the way the brain processes emotional information
— 6 Apr 2011 | HealthDrugs like marijuana act on naturally occurring receptors in the brain called cannabinoid receptors. However, the mechanisms by which these drugs produce their sensory and mood altering effects within the brain are largely unknown. Research led by Steven Laviolette at The University of Western Ontario has now identified a critical brain pathway responsible for the effects of cannabinoid drugs on how the brain processes emotional information. The findings, published in The Journal of Neuroscience, also help to explain the possible link between marijuana use and schizophrenia…
