What determines the number of species in a given area? The amount of energy available to organisms (an areas primary productivity) has been shown to be a key determinant of plant and animal biodiversity. However, it is not known if primary productivity can affect bacterial biodiversity. In an article to appear in the July 2003 issue of Ecology Letters, researchers led by a team at Stanford University report for the first time that primary productivity can, in fact, influence the diversity of bacterial communities.
They used a series of experimental ponds to demonstrate that increasing primary productivity can alter the number of taxonomic groups of bacteria present, and that the nature of this response can vary among different bacterial taxonomic groups. Bacteria may well comprise the majority of the earths biodiversity, and understanding the relationship between primary productivity and bacterial diversity is an important step toward understanding the processes responsible for the maintenance of bacterial biodiversity.

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
