Plants, like animals, employ hormones as messengers, which coordinate growth and regulate how they react to the environment. One of these plant hormones, auxin, regulates nearly all aspects of plant behavior and development, for example phototropism, root growth and fruit growth. Depending on the context, auxin elicits a range of responses such as cell polarization or division. In this week's edition of Science (DOI:10.1126/science.1245125), a team of researchers including Jiri Friml from IST Austria and led by Zhenbiao Yang of the University of California, Riverside, report finding the molecular mechanism by which the plant hormone auxin affects the organization of the cell's inner skeletons.

Vast fields of sunflowers, sprawling pine trees and slim cypresses, as well as vineyards as far as the eye can see - these are typical memories of Tuscany for all those who have been there. By contrast, Professor Dr. Beate Michalzik from the Friedrich Schiller University of Jena and her colleagues are interested in the more barren aspects of the region in Central Italy: In a study the Jena geographers analyzed the condition of the soil in the region known as 'Crete Senesi' between Florence and Grosseto, whose hills are typically characterized by erosion - for the moment at least, because the so-called badlands of Tuscany are acutely endangered.

Researchers from the University of Liverpool are leading a new campaign to tackle a disease in cattle that costs the UK economy £300m each year.

The £1 million project will look at how to improve the detection and control of liver fluke, a disease that is transmitted by the dwarf pond snail and is found on over 75% of UK dairy farms.

A comprehensive new study of global food supplies confirms and thoroughly documents for the first time what experts have long suspected: over the last five decades, human diets around the world have grown ever more similar-by a global average of 36 percent-and the trend shows no signs of slowing, with major consequences for human nutrition and global food security.
