Back in August, the FDA declared that bisphenol A, a substance found in many different kinds of plastics (including baby bottles) was safe for use in products that touch human food and drink. However, this decision is now being reexamined. Bisphenol A can potentially mimic estrogen in the human body and it may be connected to heart and liver disease.

Even with the doubts over whether BPA is truly harmful, several manufacturers have begun to make and advertise baby bottles and other products as BPA-free.

Thousands of scientists could be unwittingly ruining their own experiments merely by using standard plastic lab equipment, according to a new study. These findings may have strong implications for the methodology of basic research.

Andrew Holt, a researcher at the University of Alberta in Edmonton, Canada, was looking at how drugs affected the human enzyme monoamine oxidase B when he noticed that the drugs seemed to be inhibiting enzyme activity at much lower concentrations than they should

Bisphenol-a is a molecule found in many common rigid plastics. It also acts as an estrogen mimic in many different types of animals, including humans, causing or potentially causing lowered sperm count, increased risk of breask cancer, infertility in men and both toxic and neurotoxic effects. The Canadian government is preparing to label bisphenol-a as "toxic," and thereby forbidding it to be used in plastics that are meant to contain food or drink, such as baby bottles, water bottles and the linings of cans

Researchers announced this week that they are perfecting a procedure designed to turn pollution into a type of plastic used to make everything from DVDs to eyeglass lenses. The effort is being touted as a way to capture and use climate change–causing carbon dioxide (CO2) emissions from coal-fired power plants and other sources instead of releasing it into the atmosphere or burying it underground.
