Couples live together for convenience, not to test marriage
Many couples who move in together don't do it with marriage in mind, a small study of New York City residents suggest. Nearly all of the people interviewed who lived with a boyfriend or girlfriend said the major impetus was finances, convenience or housing needs.

Why athletes get injured
Some sportspeople are more prone to injury than others, and it's all to do with combinations of movement rather than fitness. Based on the performance of cricket players, mathematicians have created a model of the body that shows combinations of joint movements. Where a player is unable to modify a certain movement, the repeated action is more likely to cause an injury.

Spring through fall, cities are greener longer than neighboring rural regions
Summer can sometimes be a miserably hot time for city dwellers, but new research shows that an urban setting allows plants to bask in a hot-house environment that keeps them greener longer. Recent NASA-sponsored research from a team of geographers in Boston University's Center for Remote Sensing shows that the growing season for vegetation in about 70 urban areas in North America is, on average, 15 days longer than that in surrounding rural regions.

The brain activation of a group of high-functioning autistic participants was measured using functional MRI during sentence comprehension and the results compared with those of a Verbal IQ-matched control group. The groups differed in the distribution of activation in two of the key language areas. The autism group produced reliably more activation than the control group in Wernicke's (left laterosuperior temporal) area and reliably less activation than the control group in Broca's (left inferior frontal gyrus) area. Furthermore, the functional connectivity, i.e. the degree of synchronization or correlation of the time series of the activation, between the various participating cortical areas was consistently lower for the autistic than the control participants. These findings suggest that the neural basis of disordered language in autism entails a lower degree of information integration and synchronization across the large-scale cortical network for language processing. The article presents a theoretical account of the findings, related to neurobiological foundations of underconnectivity in autism.
