The natural vegetation covering the globe looks like it does because of the climate, doesnt it? Forests are found where water is abundant and it is not too cold, deserts are found where it is dry. This is what our intuition tells us – but it is not always true.
New research carried out by Bond, Woodward and Midgley from University of Cape Town, University of Sheffield and the South African National Biodiversity Institute of and published in the February 2005 issue of New Phytologist has shown that a potent force overrides climate in shaping vegetation – fire.
Much of the world is covered by vegetation that seems out of place, for example in Mediterranean regions of South Africa low shrublands are found where rainfall is great enough to support forests. We also know, from satellite imagery, that wildfires are a global phenomenon occurring on all vegetated continents. Bond et al. suspected that fires are common in areas where vegetation does not "fit" the climate. If true, this suggests that fire has a major effect on the ecosystems of the world. So, how different would the world look if we could switch fire off?

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...

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...
