     <title>A RANK insider resolving the enigma of the fever chart</title>
   	 <description>Mammals have evolved a complex system for controlling bone remodeling. Babies require calcium for healthy bones and they obtain it from their mother's milk. Nursing mothers release calcium from their bones. Surprisingly, however, the same system also plays a key part in the control of fever and of female body temperature. This finding is reported in a paper in this week's issue of Nature from Josef Penninger's group at the IMBA in Vienna, Austria.</description>

     <title>How Did Evolution Begin?</title>
   	 <description>(PhysOrg.com) -- Life's ability to replicate itself is essential for evolution, yet even the simplest kind of replication requires a relatively complex system. So what kind of non-replicating system might have served as the predecessor of evolution, paving the way for life as we know it? The answer, according to a recent study, is a kind of "prelife" -- a chemical system that can lead to information and diversity, and that is capable of selection and mutation, but does not yet have the ability to self-replicate.</description>

     <title>Scientists find universal rules for food-web stability</title>
   	 <description>The findings, published in this week's issue of Science, conclude that food-web stability is enhanced when many diverse predator-prey links connect high and intermediate trophic levels. The computations also reveal that small ecosystems follow other rules than large ecosystems: differences in the strength of predator-prey links increase the stability of small webs, but destabilize larger webs.</description>

     <title>Social scientist suggests new research framework to study complex systems</title>
   	 <description>The often-used one-size-fits-all approach to policies aimed at achieving sustainable social-ecological systems needs to be updated with a diagnostic tool to help scholars from multiple disciplines better frame the question and think through the variables, asserts social scientist and political economist Elinor Ostrom.</description>

     <title>A global model for the origin of species independent of geographical isolation</title>
   	 <description>(PhysOrg.com) -- The tremendous diversity of life continues to puzzle scientists, long after the 200 years since Charles Darwin's birth.  However, in recent years, consistent patterns of biodiversity have been identified over space, time organism type and geographical region.</description>

     <title>New book suggests Earth perhaps not such a benevolent mother after all</title>
   	 <description>(PhysOrg.com) -- In the past 50 years it has become commonplace to think of Earth as a nurturing place, straining mightily to maintain equilibrium so that life might continue and flourish.</description>

     <title>Tough times, complex systems -- a modernisation story</title>
   	 <description>(PhysOrg.com) -- Tough economic times call for tough measures to remain competitive. That goes for software modernisation as well. A European project has just released a prototype of a software engineering platform that could help companies save time, money and energy as they scramble to upgrade complex IT systems. The timing could not be better.</description>

     <title>Being Isaac Newton: Computer derives natural laws from raw data</title>
   	 <description>If Isaac Newton had access to a supercomputer, he'd have had it watch apples fall - and let it figure out the physical matters. But the computer would have needed to run an algorithm, just developed by Cornell researchers, which can derive natural laws from observed data.</description>

     <title>Synthetic biology yields clues to evolution and the origin of life</title>
   	 <description>Researchers in the field of synthetic biology are still a long way from being able to assemble living cells from scratch in the laboratory. But according to biochemist David Deamer of the University of California, Santa Cruz, their efforts are yielding clues to the mystery of how life began on Earth.</description>

     <title>Scientists create working artificial nerve networks</title>
   	 <description>Scientists have already hooked brains directly to computers by means of metal electrodes, in the hope of both measuring what goes on inside the brain and eventually healing conditions such as blindness or epilepsy. In the future, the interface between brain and artificial system might be based on nerve cells grown for that purpose. In research that was recently featured on the cover of Nature Physics, Prof. Elisha Moses of the Physics of Complex Systems Department and his former research students Drs. Ofer Feinerman and Assaf Rotem have taken the first step in this direction by creating circuits and logic gates made of live nerves grown in the lab.</description>

     <title>Analysis Shows Uptick Rule Vital to Market Stability</title>
   	 <description>(PhysOrg.com) -- A new study by researchers at the New England Complex Systems Institute found that interpretations of data from an SEC pilot program used to justify the repeal of the "uptick rule" in the summer of 2007 are unsound. The uptick rule was designed to limit the rapid selling of borrowed shares and was implemented after the crash of 1929 to prevent future crashes.</description>

     <title>Complex systems and Mars missions help understand how life began</title>
   	 <description>(PhysOrg.com) -- Understanding how life started remains a major challenge for science. At a European Science Foundation (ESF) and COST ‘Frontiers of Science` conference in Sicily in October, scientists discussed two new approaches to the problem. The first applies complex systems theory to the chemistry that preceded early life. The second involves studying Mars, which may yield ample evidence about what Earth was like when life evolved.</description>
