The development of a new organism from the joining of two single cells is a carefully orchestrated endeavor. But even before sperm meets egg, an equally elaborate set of choreographed steps must occur to ensure successful sexual reproduction.

Changes at the Grocery Store Could Turn the Burden of Shopping with Children on Its Head

Avoiding power struggles in the grocery store with children begging for sweets, chips and other junk foods – and parents often giving in – could be helped by placing the healthier options at the eye level of children and moving the unhealthy ones out of the way.
