In this animation you can see how metastasis and angiogenesis occur. Metastasis, or metastatic disease, is the spread of a cancer from one organ to another. This is first animation from series about oncology and cancer genesis.
In popular culture, mathematics is often deemed inaccessible or esoteric. Yet in the modern world, it plays an ever more important role in our daily lives and a decisive role in the discovery and development of new ideas - often behind the scenes.
In a rare case of having their cake and eating it too, scientists have developed a toolset that allows them to explore the complex interior of tiny, multi-layered batteries they devised. It provides insight into the batteries' performance without destroying them.
Tractor beam technology, if it were to exist, would be based on waves that go in the opposite direction, converging from out in space onto the point of origin. Researchers now showed that the idea may not be all science fiction.
One thousand billion operations per second - this peak value is achieved by semiconductor nano-lasers developed by physicist at the University of Jena together with their colleagues from Imperial College London.
Reflection zone plates enable lighter elements in material samples will be efficiently and precisely detected using scanning electron microscopy by providing high resolution in the range of 50-1120 eV.
Researchers found that by adding a specific atomic thin film layer to a transistor, the layer acted as a filter for the energy that passed through it at room temperature. The signal that resulted from the device was six to seven times steeper than that of traditional devices. Steep devices use less voltage but still have a strong signal.
A new method developed for studying battery failures points to the potential next step in extending lithium ion battery lifetime and capacity, opening a path to wider use of these batteries in conjunction with renewable energy sources.
