In a study in ACS' journal Environmental Science & Technology, they describe hints that one flame retardant, banned years ago in some areas, actually remains in use. "To the authors knowledge, this is the first study to report on flame retardants in baby products," the report states.
Heather M. Stapleton and colleagues point out that health concerns led to a phase-out in use of penta brominated diphenyl ethers (pentaBDE), once the most popular flame retardant, prior to 2004. Flame retardants are added during manufacture to reduce the risk of polyurethane foam catching fire and to slow down burning if it does. Seeking to meet government flammability standards, manufacturers then turned to other flame retardants, which in many cases, have less health data available. The situation left gaps in knowledge about exactly which flame retardants were being used in polyurethane foam products, and at what concentrations. Stapleton's group set out to fill those gaps.
They detected potentially toxic flame retardants in 80 percent of the polyurethane foam samples collected from 101 common baby products. Among them were compounds associated with pentaBDE, suggesting that the substance - banned in 172 countries and 12 U.S. states - still remains in use, as well as two potential carcinogens, TCEP and TDCPP. "Future studies are therefore warranted to specifically measure infants exposure to these flame retardants from intimate contact with these products, and to determine if there are any associated health concerns," the report states.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
