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.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
