The gradual subduction of the Juan de Fuca plate beneath the North American plate puts tremendous stress on the seafloor, creating cracks and fissures, hydrothermal vents, seafloor spreading, and literally hundreds of small earthquakes on a near-daily basis.
Now a North American team of scientists has documented for the first time a new phenomenon – the creation of a void in the seafloor that draws in – rather than expels – surrounding seawater. They report their discovery in the July 15 issue of the journal Nature.
Oregon State University oceanographer Robert Dziak said the discovery is important because it adds a new wrinkle to scientific understanding of seafloor spreading, the fundamental process of plate tectonics and the creation of ocean crust. Dziak has a dual appointment with the National Oceanic and Atmospheric Administration’s Pacific Marine Environmental Laboratory.

Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz (Germany) together with scientists from Dresden, Leipzig, Sofia (Bulgaria) and Madrid (Spain) have now developed and characterized a novel, metal-organic material which displays electrical properties mimicking those of highly crystalline silicon. The material which can easily be fabricated at room temperature could serve as a replacement for expensive conventional inorganic materials used in optoelectronics.
Silicon, a so called semiconductor, is currently widely employed for the development of components such as solar cells, LEDs or computer chips. High purity...

Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
