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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
