Curcumin, the yellow pigment found in the spice turmeric and a key ingredient in yellow curry inhibits melanoma cell growth and stimulates tumor cell death, according to a new study. Published in the August 15, 2005 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study also elucidates curcumins intracellular mechanisms of action in this type of tumor.
As well as showing antioxidant and anti-inflammatory effects, curcumin has been shown to have anti-cancer properties. In other tumors, it has been demonstrated to inhibit tumor growth and stimulate apoptosis, an intracellular mechanism for cells of all types to "kill" themselves. To evaluate the compounds efficacy in melanoma, researchers led by Razelle Kurzrock, M.D. of the University of Texas M. D. Anderson Cancer Center in Houston treated three melanoma cell lines with curcumin at different doses and for different duration.
Results show that curcumin treatment decreased cell viability in all three cell lines in a dose-dependent manner. Moreover, curcumin induced apoptosis in tumor cells at high concentrations for short periods of time and low concentrations for long periods of time--a new finding in the study of curcumin.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
