Researchers in Finland are working to develop a comprehensive, multidisciplinary model of the carbon cycle and its impacts on climate change in northern ecosystems. The focus of work in the Academy of Finland’s Global Change Research Programme (FIGARE) has been on the uptake and release of carbon in different ecosystem reservoirs, the atmosphere, vegetation, trees, forest land and lakes.
‘The carbon dioxide content in the earth’s atmosphere is slowly and steadily increasing. Given the results we have accumulated over the years using highly accurate instruments that measure carbon dioxide flows, it is now possible by means of meteorological methods to establish what kinds of sinks and sources there are for carbon dioxide, to know where carbon dioxide is stored and where it is released from,’ says Professor Timo Vesala from the University of Helsinki.
In Finland, atmospheric carbon dioxide is regularly monitored among other things by means of point measurements in forest environments. This method yields local information on how much carbon dioxide is stored in forests and how much is in turn released. ‘This is important and valuable information even though it sheds no light on the bigger picture of carbon exchange. It is used by researchers to try and model and predict the process of carbon exchange in the forest ecosystem. The model we are now working on will be useful if it can predict factors that have an impact on the carbon cycle in different weather conditions,’ Professor Vesala continues.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
