McGill research shows increased carbon dioxide levels decrease algae growth
The doomsayers may be right: our children may not inherit a bountiful and green world. According to researchers at McGill University, we have been overestimating the ability of plants to counteract the greenhouse effect. Their findings, published in the September 30 issue of Nature, suggest changing conditions in the earths atmosphere may have more harmful effects on plant life than previously believed.
The research, led by McGill University biologist Graham Bell, looked at the response of algae to high carbon dioxide concentrations. Their findings showed that the plants could not adapt to high carbon dioxide conditions. This disproves the previous assumption that plants can take up extra carbon dioxide in the environment. According to Bell, these findings may be applied to other plants species. Over the next century we may see a dramatic change in all plants (including agricultural species) as our use of fossil fuels increases and generates increased carbon dioxide levels.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
