In honor of the Earth Day celebration, NASA scientists unveiled the first consistent and continuous global measurements of Earths "metabolism." Data from the Terra and Aqua satellites are helping scientists frequently update maps of the rate at which plant life on Earth is absorbing carbon out of the atmosphere.
Combining space-based measurements of a range of plant properties collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) with a suite of other satellite and surface-based measurements, NASA scientists produce composite maps of our worlds "net primary production" every 8 days. This new measurement is called net production because it indicates how much carbon dioxide is taken in by vegetation during photosynthesis minus how much is given off during respiration. Scientists expect this global measure of the biological productivity of plants to yield new insights into how the Earths carbon cycle works, a critical step toward solving the climate change puzzle.
The rate of carbon fixation through photosynthesis is a basic property of life on planet Earth. It is the basis for capturing and storing the energy that fuels our worlds living systems and forms the foundation of the food webs. The oxygen we breathe is a byproduct of this photosynthesis. According to its creators, these new net primary productivity maps provide a fascinating new insight into the intimate connection between the living world and the physical world.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
