Discovery suggests presence of diamonds in northern Saskatchewan
Researchers at the University of Alberta have found evidence that a 2,000-kilometre corridor stretching diagonally across northern Canada was under tremendous pressure to split in two about 2.7 billion years ago. It is the first evidence suggesting enormous continental landforms and plate tectonics existed that long ago. "Rifts are one hallmark of plate tectonics, and there is a huge debate in our field about whether or not large continents and plate tectonics existed on Earth in the Archean age, which is pre-2.5 billion years ago," said Dr. Larry Heaman, a professor of earth sciences at the U of A.
"Our findings suggest that a form of plate tectonics did occur in the Archean," said Dr. Russell Hartlaub, a post-doctoral fellow working with Heaman and lead author of a paper on the Archean rift discovery that appears recently in Precambrian Research.

Augsburg chemists and physicists report how they have succeeded in the extremely difficult separation of hydrogen and deuterium in a gas mixture.
Thanks to the Surface Acoustic Wave (SAW) technology developed here and already widely used, the University of Augsburg is internationally recognized as the...
Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
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...
