Greening seems to have increased during the 1980s and 1990s in the northern hemisphere from the arctic regions down to the 35th parallel of latitude (roughly southern Europe). This has been shown by measurements from space satellites. Some observers, however, have doubted the reliability of these measurements. In the latest issue of Science, a research team from the Institute for Climatic Impacts Research in Potsdam, the Max Planck Institute for Biogeochemistry in Jena, and Lund University presents new findings that support the satellite observations.
The research team has fed in the current values for temperature, precipitation, solar radiation, cloud cover, and carbon dioxide content during the period 1982-1998 in a model for vegetation growth. It is called the LPJ Model and was developed at Lund by Colin Prentice, Stephen Sitch, and Ben Smith. Of the three, the former two are now in Jena, whereas ecologist Benjamin Smith is associated with the Department of Physical Geography and Ecosystem Analysis at Lund University in Sweden.
Vegetation has been measured from space using AVHRR, Advanced Very High Resolution Radiometry. This is a spectroscopic method that can register when light reflects from the surface of green leaves.

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.
A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...
Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
