The study found that nondaily cannabis use decreased among those aged 12 to 25 and 35 to 49 before 2007, and increased among all adults after 2007, particularly among adults 26 to 34.

| Finding genes controlling ovarian reserve could hold key to better female fertility care
|
 Jackson Laboratory Assistant Professor Ewelina Bolcun-Filas, Ph.D., is looking at how multiple genetic factors regulating oocyte development determine the differences in each woman's ovarian reserve. Bolcun-Filas has received a five-year grant totaling $2,165,475 from the Eunice Kennedy Shriver National Institute of Child Health and Human Development to investigate these genetic factors, using special, genetically diverse mouse populations.
