CFRP recycling—into the battery instead of the garbage

The Fraunhofer ICT uses recycled, small chopped carbon fibers (top) to produce bipolar plates (bottom) for batteries and fuel cells. Credit: Fraunhofer ICT Carbon fiber-reinforced plastics are gaining importance as components of aircraft. The trend is increasing the need for sustainable recycling concepts. At the ILA from April 25 to 29, 2018 in Berlin, Fraunhofer will present a technology that converts recycled carbon fibers into materials for batteries and fuel cells. This saves costs, improves the CO2 balance and opens…

Certain immune cells behave differently in HIV-infected patients than they do in healthy individuals — ScienceDaily

A team of chemical and biomedical engineers from the Cockrell School of Engineering at The University of Texas at Austin, in collaboration with researchers from the University of Pennsylvania, have discovered that HIV-infected patients experience a dysfunction in a certain type of immune cell: the follicular helper T (Tfh) cell. In a paper published today in Science Immunology, the authors outline how, through combining a sophisticated sequencing technique with a mass cytometry method (the measurement of cell characteristics), they discovered…

Brain development disorders in children linked to common environmental toxin exposures — ScienceDaily

Exposures of pregnant women and children to common thyroid-hormone-disrupting toxins may be linked to the increased incidence of brain development disorders, according to a review published in Endocrine Connections. The review describes how numerous, common chemicals can interfere with normal thyroid hormone actions, which are essential for normal brain development in foetuses and young children, and suggests a need for greater public health intervention. Maternal thyroid hormones (TH) are essential for normal brain development of children and previous human studies…

Exposure to low levels of BPA during pregnancy can lead to altered brain development — ScienceDaily

New research in mice provides an explanation for how exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated “safe” human exposure level, can lead to altered brain development and behavior later in life. The research will be presented Monday, March 19 at ENDO 2018, the 100th annual meeting of the Endocrine Society in Chicago, Ill. BPA is a chemical that is added to many commercial products, including water bottles, paper receipts,…

Making better hair dyes — ScienceDaily

Graphene, a naturally black material, could provide a new strategy for dyeing hair in difficult-to-create dark shades. And because it’s a conductive material, hair dyed with graphene might also be less prone to staticky flyaways. Now, researchers have put it to the test. In an article published March 15 in the journal Chem, they used sheets of graphene to make a dye that adheres to the surface of hair, forming a coating that is resistant to at least 30 washes…

PET myocardial perfusion imaging more effective than SPECT scans in detecting coronary disease — ScienceDaily

Patients who receive cardiac positron emission testing (PET) imaging instead of single photon emission computed tomography (SPECT) scan experienced a significant increase in the detection of severe obstructive coronary artery disease, according to researchers at the Intermountain Medical Center Heart Institute in Salt Lake City. Both, PET and SPECT scans are nuclear imaging techniques that provide metabolic and functional information of the heart. PET scans provide better image resolution and quality, but have not yet gotten widespread adaptation compared to…

Is your stress changing my brain? Stress isn’t just contagious; it alters the brain on a cellular level — ScienceDaily

In a new study in Nature Neuroscience, Jaideep Bains, PhD, and his team at the Cumming School of Medicine’s Hotchkiss Brain Institute (HBI), at the University of Calgary have discovered that stress transmitted from others can change the brain in the same way as a real stress does. The study, in mice, also shows that the effects of stress on the brain are reversed in female mice following a social interaction. This was not true for male mice. “Brain changes…
