A new mathematical model of ecology created by University of Chicago scientists provides the most accurate reproduction to date of natural biodiversity, according to a new paper in the journal Nature. For almost a century, ecologists have conceptualized an ecosystem as the sum of pairwise interactions, such as predator and prey, herbivore and plant, or parasite and host. However, equations based on that theory failed to replicate the diversity and resilience of natural ecosystems. Building upon previous work that modeled competition between species as similar to a game of rock/paper/scissors, a team led by Stefano Allesina, Professor of Ecology & Evolution at the University of Chicago, found that adding additional competitors could generate stable and robust model ecosystems.

For the last two years, the Chameleon testbed has enabled researchers around the world to push the limits of cloud computing in areas such as astronomy, cybersecurity, and education. The project, led by the Computation Institute, has thus far served over 14000 users as an experimental, highly customizable environment where they can test new architectures and applications, at the kinds of scale needed for today's big data projects. To commemorate established achievements and plan for the future of the testbed, Chameleon will host its first user meeting this September at Argonne National Laboratory.

Using lists of names collected from publicly available websites, two University of Chicago researchers have revealed distinctive patterns in higher education systems, ranging from ethnic representation and gender imbalance in the sciences, to the presence of academic couples, and even the illegal hiring of relatives in Italian universities.
