Women with ductal carcinoma in situ, a non-invasive form of breast cancer, are more likely to experience a recurrence after treatment if their DCIS is of a high nuclear grade or is detected by palpation during a breast examination, according to a study in the November 19 issue of the Journal of the National Cancer Institute.
DCIS accounts for about 20% of all newly diagnosed cases of breast cancer in the United States and is initially treated surgically, either by mastectomy (removal of the entire breast) or lumpectomy (removal of the tumor and minimal surrounding tissue). Some women will experience a recurrence, but it is unclear what characteristics are associated with the risk of recurrence.
Karla Kerlikowske, M.D., of the San Francisco Veterans Affairs Medical Center, and her colleagues examined information about 1,036 women in the San Francisco Bay area who were age 40 or older when diagnosed with DCIS and treated with lumpectomy alone.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

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...
