POPSViruses can catch colds, says study that redefines life itself Prof La Scola and his colleagues were surprised to spot a smaller type of virus attached to the virus-making factory inside infected cells. The new virus - Sputnik - was unable to infect cells by itself but seemed to hijack the larger to achieve its infectious aims. By regulating the growth and death of plankton, giant viruses - and satellite viruses such as Sputnik - could be a major influence on ocean nutrient cycles and climate. "These viruses could be major players in global systems," Nature is told by Prof Curtis Suttle, an expert in marine viruses at the University of British Columbia in Vancouver.

POPSBrain Imaging Helps Explain Behavior The fMRI study showed that, during the viewing of angry faces, the activity of a structure called the insula, involved in the response to unpleasant situations, depended on which version of the CREB1 gene a participant inherited. “We were surprised to see that variation in the CREB1 gene would account for more than 20 percent of the difference in how healthy participants weighed different options and expressed specific preferences,”

POPSArt of the DEAD: Ancient Irish High Cross Art
"About 200 of them survive, in varying condition, many of them decorated with scriptural scenes. This iconography, some of it simple, some of it ingeniously complex, has been meticulously explored by archaeologist/art historian Dr Peter Harbison in his definitive three volume study, The High Crosses of Ireland (Bonn, 1992). It is a major work which is yet to be published in Ireland. In it Harbison has identified ancient Christian Rome from AD 400 onwards as the most likely inspiration for the Irish crosses, "but the figure sculpture may have come to our shores largely through the filter of the empire of Charlemagne and his sons in central Europe". The compositions for the biblical panels on the Irish crosses are often similar to those found on frescoes in continental churches. " During the past 20 years or so, several of the high crosses have been moved indoors in an attempt to prevent further erosion. One of the first to be relocated was the cross at the Rock of Cashel which was re
