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.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
