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.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
