As a treatment for advanced cancer, shark cartilage fails to benefit patients and its adverse effects lead to poor compliance. A clinical trial published in the July 1, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, finds there was no difference in overall survival or quality of life between patients who received shark cartilage and those who received a placebo.
Some experiments have shown that some forms of shark cartilage possess a modest ability to slow the growth of new blood vessels in laboratory cell cultures and in animals, but the effects on humans are not known. Interest in shark cartilage grew after a television news magazine aired a segment in 1993 that showed patients with advanced cancer in Cuba who had gone into remission after being treated with shark cartilage. The results of the study were never published in a peer-reviewed medical journal, and the National Cancer Institute (NCI) later concluded the results of the Cuban study were "incomplete and unimpressive."
Mayo Clinic Oncologist Charles L. Loprinzi, M.D., and his colleagues in the North Central Cancer Treatment Group (NCCTG) designed and conducted a randomized, placebo-controlled, double-blind clinical trial to investigate the efficacy associated with shark cartilage as a treatment for breast and colorectal cancer.

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...
