The northernmost part of the Baltic Sea, between Finland and Sweden, recently provided an ideal location for scientists to successfully address critical issues relating to sea ice validation before CryoSat is launched in September.
Unlike last years CryoSat Validation Experiments (CryoVEx 2004), which focussed on land ice and took place in Greenland and the Canadian Arctic, the recent validation activities in the Baltic scrutinised issues relating to sea ice. The experiment examined the possible sources of error that could arise in the sea-ice thickness maps that will be generated using data from ESAs ice mission CryoSat.
Errors can arise, for example, where a snow layer is present on top of the sea ice. The weight of the snow tends to push the ice floes lower into the water, so that CryoSat, which translates the height of the ice surface above the waterline into ice thickness data, would underestimate the true thickness of the ice. Validation campaigns, thus, form a critical component of the whole mission; they provide the only means to reach a comprehensive assessment of how accurate CryoSat-derived ice thickness maps are.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
