Every family unit is a complex social network influenced by numerous inputs. In nature, social organizations at the family and small-group level can range from violent to peaceful, monogamous to polyandrous, segregated to sharing work. On Wednesday August 4, 2004, scientists will gather for the symposium, "Family Dynamics: the Evolution and Consequences of Family Organization." The session, to be held during the Ecological Society of America’s 89th Annual Meeting in Portland, Oregon, will examine the varied structures of social organization and the conditions, from genetics to habitat, that affect the evolution and development of these groups.
Michael Neubert (Woods Hole Oceanographic Institution) will begin the session with an overview of the theories for family organization and implications of family structure on populations in his talk, "Family Dynamics: An introduction to the symposium with an example from invasion dynamics."
Andrew Dobson (Princeton University) will follow Neubert, describing how the social organization of hosts can affect the transmission of diseases in, "The coevolution of host social organization and pathogen transmission." Examining data from primates and carnivores, along with theoretical models, Dobson will also discuss the possible role of pathogens in shaping populations.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
