The c-myc gene is commonly activated in a variety of human tumors. As a new report in the October 1 issue of Genes & Development shows, scientists are gaining a better understanding as to why.
Dr. John Cleveland and colleagues at St. Jude Childrens Research Hospital have discovered that c-Myc is essential for tumor development, as it regulates factors necessary for the growth of blood vessels into tumors – lending a new potential target to anti-angiogenic cancer therapies.
The myc family of oncogenes (c-myc, N-myc, and L-myc) function in the control of cell proliferation, differentiation, and tumorigenesis. Although it has long been recognized that c-Mycs positive effect on cell proliferation can contribute to cancer development, scientists have also suspected that c-Myc has additional roles in the progression of malignancy. Dr. Cleveland and colleagues have discovered such a role: c-Myc is essential for tumor angiogenesis.

For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
An interdisciplinary research team at the Technical University of Munich (TUM) has built platinum nanoparticles for catalysis in fuel cells: The new size-optimized catalysts are twice as good as the best process commercially available today.
Fuel cells may well replace batteries as the power source for electric cars. They consume hydrogen, a gas which could be produced for example using surplus...

Physicists at the Max Planck Institute for Nuclear Physics in Heidelberg report the first result of the new Alphatrap experiment. They measured the bound-electron g-factor of highly charged (boron-like) argon ions with unprecedented precision of 9 digits. In comparison with a new highly accurate quantum electrodynamic calculation they found an excellent agreement on a level of 7 digits. This paves the way for sensitive tests of QED in strong fields like precision measurements of the fine structure constant α as well as the detection of possible signatures of new physics.

Quantum electrodynamics (QED) describes the interaction of charged particles with electromagnetic fields and is the most precisely tested physical theory. It...
