The Consumption of fruit and vegetables is associated with a lower cardiovascular disease risk. Smoking may affect the strength of this association. The objective of this study was to compare the relationship between the frequency of fruit and vegetables intake and cardiovascular disease risk in male current, former and never smokers.A prospective study in men…

Reports in Science, a team from the International Human Microbiome Consortium (Nelson et al. and Qin et al describe the genome sequence of the bacterial species from the human microbiome. The contribution…
Read more\ Skyrmion makeover Celebrating the treasures of topological twists. Sometimes a scientific idea falls into obscurity as researchers turn their attention elsewhere, yet contains such mathemati¬cal beauty that it is revived again and again. Such is the story of the skyrmion: a concept that has had several makeovers since it was first formulated in the…

Read moreThere is insufficient information about the combined effects on breast cancer incidence of low-penetrance genetic susceptibility polymorphisms and environmental factors (reproductive, behavioural, and anthropometric risk factors for breast cancer). This study looks for evidence of gene-environment interactions, and compared genotypic relative risks for breast cancer across the other risk factors in a large UK prospective…
Read moreA ribosome in action The manufacture of proteins by ribosomes involves complex interactions of diverse nucleic-acid and protein ligands. Single-molecule studies allow for the first time, scientists to follow the synthesis of full-length proteins in real time. This is clearly demonstrated in articles by Bakmann and Uemera et al in Nature 15th April 2010 .Protein…
