A new study has revealed a mechanism that counters established thinking on how the rate at which tectonic plates separate along mid-ocean ridges controls processes such as heat transfer in geologic materials, energy circulation and even biological production.
The study also pioneered a new seismic technique – simultaneously shooting an array of 20 airguns to generate sound -- for studying the Earths mantle, the layer beneath the 10- to 40-kilometer-deep crust on the seafloor. The research, led by the Georgia Institute of Technology with funding from the National Science Foundation (NSF), will be reported in the Dec. 9, 2004 issue of the journal Nature.
"Mid ocean ridges produce most of the volcanism on the Earth, releasing a lot of heat – in some places enough to support large biological communities on the seafloor," said Daniel Lizarralde, lead author of the Nature paper and an assistant professor in the Georgia Tech School of Earth and Atmospheric Sciences.

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
