Under the EU Sixth Framework Programme (FP6) for Research and Development (2002-2006) 2.2 million Euros have been awarded to the 3DGENOME-research program. FP6 is one of the worlds largest research programmes, with a budget of 17.5 billion Euros, of which around 3 billion Euros is available for life sciences research. The main objective of the 3DGENOME program is to understand how the human genome, consisting of a number of very long DNA molecules that carry our genetic information, are coiled up inside our cells. By changing the way that DNA is folded, cells control the switching on and off genes, which are the units of genetic information. Results will help to understand errors in our genetic system that for instance result in tumour formation. The research program is conducted by a consortium of seven European partners and is coordinated by the Swammerdam Institute for Life Sciences of the University of Amsterdam in The Netherlands.
The human cell orchestrates the activity of its about 35,000 genes in an extremely efficient and reliably way. These genes are bits of information on DNA. Each of our cells contains DNA molecules with a total length of 2 meters, folded inside a cell nucleus of only 1/100th of a millimetre diameter. This is comparable to packing 20 km of thin wire inside just a tennis ball. Evidently, the DNA thread is extremely folded inside a cell. This folding plays an important role in how a cell switches genes on and off, thereby deciding how the cell behaves. Folding decides whether a cell becomes a skin cell, a liver cell or a neuron, and whether a cell is healthy or sick.
The 3dgenome program should lead to a breakthrough in our understanding of how our genome functions. Using advanced microscopic techniques in combination with novel data analysis software, the consortium of European scientists intend to establish a three-dimensional map of the DNA fibre inside the human cell. This spatial structure will be related to patterns of switched off and stitched on genes along the DNA molecule.

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...
