We all want to trust “the system” when it comes to issues such as potentially toxic chemicals that could affect our health. But new reports about polycarbonate baby bottles are disturbing. Research from the federal National Toxicology Program is said to raise ‘’some concern” about bisphenol A potentially leaching from polycarbonate baby bottles and other products. Rats exposed to the chemical showed disturbing changes, including some linked to cancer. Canadian health officials say bisphenol A may endanger humans and any may ban the substance from baby bottles. Polycarbonate producers such as Sabic Innovative Plastics are referring questions to Dr. Steven Hentges, a polycarbonate expert at the American Chemistry Council. The ACC has released a very guarded statement, which says that the new studies confirm their position that exposure to BPA is negligible. Dr. Hentges calls on the U.S. government to conduct more studies to affirm the safety of BPA. I wonder what Dr. Hentges is telling his family members about use of polycarbonate baby bottles, which are typically exposed to high heat in a dishwasher? I’ll bet he’s telling them to take no chances. Use safer BPA-free alternatives. Why take any chances? There are limits (big limits) to how far we should go to protect our chemical industry.
It’s not clear to what extent there are also health concerns about epoxy resins, which are typically made with bisphenol A and widely used as a coating in food n beverage cans.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Engineers at the University of California, San Diego are designing a robotic arm that takes inspiration from the loose, flexible, yet very strong structure of the armored plates on a seahorse's tail.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
The latest model of Liquid Robotics' Wave Glider autonomous, unmanned marine vehicle (UMV), the SV3, is reportedly the world's first hybrid wave- and solar-power-propelled unmanned ocean robot.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
