Is climate change likely to increase disease in corals?
...ease that is spreading rapidly, leaving stripes of dead corals like ribbons of death in its wake. In a new study published by PLoS Biology, John Bruno, Amy Melendy, and colleagues show that the interaction between anomalously high ocean temperatures and the extent of coral cover is likely to account for t...Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host
...ther microbes that might grow in the corpse of the dead insect. To test their findings, the researchers produced a mutant Photorhabdus that is unable to make ST. Without ST, the bacteria were less virulent. The researchers then used a technique known RNA interference to prevent the insects from produci...Researcher receives $1.8M AIDS-related grant
