PLoS Biology : Publishing science, accelerating research

How do social animals, from insects to humans, limit the spread of disease by deploying community-level responses to pathogens? This primer , describing research by Sylvia Cremer and colleagues , highlights active immunization of healthy ants by infected ants as one intriguing example. You can also listen to the accompanying PLoS Podcast , featuring an interview with the authors.

The Micro- and Nanotechnology Research Group of the Universitat Politècnica de Catalunya (UPC) has produced silicon photovoltaic cells with a conversion efficiency of 20.5%, the highest level achieved in Spain using this material. This figure is comparable to results obtained by leading research groups in the field at the international level.

Last year’s artificial cell was created by J. Craig Venter and colleagues using a "top-down" approach: they replaced the genome of a bacterium, Mycoplasma genitallium , with a synthetic DNA sequence they designed to contain the minimum set of genes required for life. It was an amazing feat, but all of the machinery necessary to make the cell work was already present within the bacterial shell.
