| History is key factor in plant disease virulence Posted: 21 Apr 2012 05:39 PM PDT The virulence of plant-borne diseases depends on not just the particular strain of a pathogen, but on where the pathogen has been before landing in its host, according to new research results.  |
| Mild winters are detrimental to butterflies Posted: 20 Apr 2012 09:38 AM PDT Mild winters, such as the one many of us just experienced, can be taxing for some butterfly or possibly other species.  |
| Posted: 20 Apr 2012 07:55 AM PDT A scattergun approach to borehole drilling in Africa is likely to be unsuccessful. This is the message from a group of researchers who have, for the first time, quantified the amount, and potential yield, of groundwater across the whole of Africa. They estimate the total volume of groundwater to be around 0.66 million km3 – more than 100 times the available surface freshwater on the continent – and hope that the assessment can inform plans to improve access to water in Africa, where 300 million people do not have access to safe drinking water.  |
