A new study that will look at 50,000 sisters of women diagnosed with breast cancer opened today for enrollment across the United States. The Sister Study, conducted by the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health, will investigate environmental and genetic causes of breast cancer. The Sister Study is the largest study of its kind to look at breast cancer risk factors.
Women of all backgrounds and ethnic groups are eligible for the study if they are between the ages of 35 and 74; live in the United States; have never had breast cancer themselves; and have a sister living or deceased who has had breast cancer. To recruit a diverse group of volunteers and to ensure the results benefit all women, researchers are especially encouraging African-American, Latina, Native American, and Asian women, as well as women 60 and older, to join the Sister Study.
Sisters may be the key to unlocking breast cancer risk mysteries. Dale Sandler, Ph.D., Chief of the Epidemiology Branch at NIEHS and principal investigator of the Sister Study said, By studying sisters, who share the same genes, often had similar experiences and environments, and are at twice the risk of developing breast cancer, we have a better chance of learning what causes this disease. That is why joining the Sister Study is so important.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
