Using models that simulate the interaction between global climate and land ecosystems, atmospheric scientists from the Lawrence Livermore National Laboratory have shown that compensating for the carbon dioxide "greenhouse effect" by decreasing the amount of sunlight reaching the planet (geoengineering) could create a more vigorous ecosystem while helping to curb global warming.
The study suggests that planetary-scale engineering projects to lessen the amount of solar radiation reaching the Earths surface will likely do little to prevent the effects of increased greenhouse gases on the terrestrial biosphere. In fact, plants could experience growth spurts.
In a paper entitled: "Impact of Geoengineering Schemes on the Terrestrial Biosphere," Livermore researchers Bala Govindasamy, Starley Thompson, Philip Duffy, Ken Caldeira and University of Wisconsin collaborator Christine Delire, modeled the impact on Earths land biosphere due to various schemes that would reduce the amount of sunlight reaching the planets surface. The research appears in the Nov. 26 online edition of Geophysical Research Letters.

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...
