The Earth Microbiome Project (EMP) is a proposed massively multidisciplinary effort to analyze microbial communities across the globe from many environments. The first EMP Conference is scheduled for June 2011 in Shenzhen, China. The goal is to understand microbes (Bacterial, Archaeal, Eukaryal and Viral) in terms of whom they are and what they do; it is the grand challenge of microbial ecology.

ScienceDaily (Jan. 12, 2011) — Geologists at Brown University and the University of Washington have a cautionary tale: Lose enough species in the oceans, and the entire ecosystem could collapse. Looking at two of the greatest mass extinctions in Earth’s history, the scientists attribute the ecosystems’ collapse to a loss in the variety of species sharing the same space. It took up to 10 million years after the mass extinctions for the ecosystem to stabilize.
The world’s oceans are under siege. Conservation biologists regularly note the precipitous decline of key species, such as cod, bluefin tuna, swordfish and sharks. Lose enough of these top-line predators (among other species), and the fear is that the oceanic web of life may collapse.
In a new paper in Geology, researchers at Brown University and the University of Washington used a group of marine creatures similar to today’s nautilus to examine the collapse of marine ecosystems that coincided with two of the greatest mass extinctions in the Earth’s history. They attribute the ecosystems’ collapse to a loss of enough species occupying the same space in the oceans, called “ecological redundancy.”

ScienceDaily (Nov. 13, 2008) — In future, polymethyl methacrylate (PMMA for short) – better known as acrylic glass – could be made from natural raw materials such as sugars, alcohols or fatty acids. Compared with the previous chemical production process, this biotechnological process is far more environmentally friendly. A new enzyme discovered by Dr. Thore Rohwerder und Dr. Roland H. Müller, called 2-hydroxyisobutyryl-CoA mutase, makes it possible to turn a linear C4 carbon structure into a branched one. Compounds of this type are precursors of MMA. Parent compounds may of course include intermediate products from the petrochemical industry. This enzyme, integrated into metabolically appropriate microorganisms, can also transform sugars and other natural compounds into the products desired. Dr Thore Rohwerder has been nominated as one of three candidates for the European Evonik research award for his discovery.
A new report released by the Wildlife Conservation Society names 12 deadly pathogens likely to spread into new geographic regions of the endangering both human and animal populations. The “deadly dozen” includes ebola, avian flu, cholera, yellow fever, tuberculosis and other diseases that could easily spread with changing temperature and precipitation patterns, causing challenges to health, health care systems, national economies, and ecosystems.
