Sport fields: Catalysts for physical activity in the neighborhood?
If you're a woman, older adult, or have higher levels of education, you're less likely to be sufficiently physically active. Those are some of the findings of a new University of Alberta study examining people's actual and perceived access to sport fields as catalysts for physical activity. View More (2012-03-12)
Bacterial plasmids -- the freeloading and the heavy-lifters -- balance the high price of disease
Studying self-replicating genetic units, called plasmids, found in one of the world's widest-ranging pathogenic soil bacteria -- the crown-gall-disease-causing microorganism Agrobacterium tumefaciens -- Indiana University biologists are showing how freeloading, mutant derivatives of these plasmids benefit while the virulent, disease-causing plasmids do the heavy-lifting of initiating infection in...

If consumers are close to fitness goals, do they prefer a larger or limited variety of products?
Consumers who believe they are making progress toward their goals are motivated by limited product variety, unlike people who think they are further from their goals, according to a new study in the Journal of Consumer Research. View More (2011-11-16)
How does a plant survive with few mates or pollinators? A European herb has figured out its own way
In plants that rely on animals for pollination, the number of seeds they produce, or their relative fitness, is influenced by pollinator visits and the successful deposition of pollen. View More (2011-11-11)
Do plants perform best with family or strangers? Researchers consider social interactions
In the fight for survival, plants are capable of complex social behaviours and may exhibit altruism towards family members, but aggressively compete with strangers. View More (2011-11-10)
