An extraordinary self-regulating heating effect that can be achieved in a particular type of magnetic material may open the doors to a new strategy for hyperthermia cancer treatment, researchers say. "This strong, self-regulated heating effect is unmatched by other materials," an investigator said. "It opens a novel design strategy for realising in vivo hyperthermia therapy."

Physicists have gained new insights into dark energy and the theory of gravitation by analyzing data from the "Planck" satellite mission of the European Space Agency (ESA). Their results demonstrate that the standard model of cosmology remains an excellent description of the universe. Yet when the Planck data is combined with other astronomical observations, several deviations emerge. Further studies must determine whether these anomalies are due to measurement uncertainties or undiscovered physical correlations, which would also challenge Einstein's theory of gravitation. Thus, the analysis of the Planck data gives major impetus for research during future space missions.

Martian colonists could use an innovative new technique to harvest energy from carbon dioxide thanks to new research. The research proposes a new kind of engine for producing energy based on the Leidenfrost effect -- a phenomenon which happens when a liquid comes into near contact with a surface much hotter than its boiling point. This effect is commonly seen in the way water appears to skitter across the surface of a hot pan, but it also applies to solid carbon dioxide, commonly known as dry ice.

Computer scientists have developed a technique that could enable virtually anyone to print out customized displays of their own in future -- in all shapes and sizes and onto various materials. A regular home printer could be used to print wafer-thin displays onto paper, so these printed displays might present custom-designed icons or even respond to touch.

Nanoparticles can function as carriers for medicines to combat lung cancer, scientists say, after developing nanocarriers that site-selectively release medicines/drugs at the tumor site in human and mouse lungs. The scientists report that this approach led to a significant increase in the effectiveness of current cancer medicines in lung tumor tissue.

When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison.

The chemical signature of water vapor emitted by combustion sources such as vehicles and furnaces has been found in the smoggy winter inversions that often choke Salt Lake City. The discovery may give researchers a new tool to track down the sources of pollutants and climate-changing carbon dioxide gas.
