A pineapple pesticide that made its way into milk in Hawaii also made its way into men's brains, and those men were more likely to develop Parkinson's disease, a study finds. It's the latest in a very long series of studies linking various pesticides to Parkinson's, which is caused by the loss of certain brain cells. More:

The varied hormones in our bodies exert their effects by attaching to specific receptors. Once this attachment is established, a hormone initiates a unique, complex chain of events that regulate our body's development and function. Think of each hormone as a member of an orchestra that is performing a demanding, perpetual symphonic work. Hormone disrupters are chemicals that interfere with this delicate process. More:

Every day thousands of people make decisions that affect the chemical market. Most decisions are about the costs, availability, and performance of products; few involve consideration of human health or the environment. If the consumer market offers an important opportunity for promoting safer chemical production and consumption systems, the amount of chemical information in the market must expand, and the number of products that take health and environment into account must increase.

Chemistry is having “an innovation crisis”, according to John Warner, co-author of the 12 Principles of Green Chemistry. “We need to ask if the way we’re training future scientists is fitting the need of society.” “Instead of enacting another law that bans or regulates a chemical or a molecule that has a toxic or environmentally destructive effect, we need to think about how we invent a product that doesn’t have that effect”, he said.
