Dissertation work on leading wave power

harminka — Tue, 09 Dec 2008 14:54:13 -0600

A technology that is adapted to the special conditions for wave energy places the wave energy technology from Uppsala on the absolute cutting edge in the world. In his dissertation, Rafael Waters presents the findings from the experimental facility located in the sea outside Lysekil, Sweden, in which he has played a leading role in designing and constructing.

A class of powerful, invisible waves hidden beneath the surface of the ocean can shape the underwater edges of continents and contribute to ocean mixing and climate, researchers from The University of Texas at Austin have found.

Weather, waves and wireless, Super strength signalling

Nanoscale devices present a unique challenge to any optical technology — there’s just not enough room for light to travel in a straight line.

Scientists find elusive waves in sun's corona

harminka — Fri, 31 Aug 2007 04:56:24 -0500

Scientists for the first time have observed elusive oscillations in the Sun's corona, known as Alfven waves, that transport energy outward from the surface of the Sun. The discovery is expected to give researchers more insight into the fundamental behavior of solar magnetic fields, eventually leading to a fuller understanding of how the Sun affects Earth and the solar system.

Bursts of waves drive immune system 'soldiers' toward invaders

Scientists have discovered that torrents of microscopic waves propel white blood cells toward invading microbes. The discovery - recorded on videotape -- holds the potential for better understanding and treatment of cancer and heart disease.

Excitation Waves patterns Found In Brain’s Visual Processing Center

harminka — Wed, 01 Aug 2007 06:29:27 -0500

Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another. But scientists at Georgetown University Medical Center discovered that visual information is also processed in a different way, like propagating waves oscillating back and forth among brain areas.

New lens device will shrink huge light waves to pinpoints
