New research suggests that bike share programs have a downside, but the program Seattle is launching this fall will have a key feature that could help mitigate it.

Researchers from the University of Washington and Washington State University looked at bicycle injury data from 10 major cities, both with and without bike share programs. They found that when a city gets a bike share program, a higher proportion of injuries to its cyclists are head injuries. 

It appears the economic recession has taken its toll on babies. Researchers have found the number of babies with severe head injuries nearly doubled in 2008 and 2009. Stress in the family seems to be a factor.
