In an unprecedented pan-cancer analysis of whole genomes, researchers at the Ontario Institute for Cancer Research (OICR) have discovered new regions of non-coding DNA that, when altered, may lead to cancer growth and progression.

Scientists at EPFL have published two papers showing how genetics affects the ability of different individuals to fight off gut infections.

A new study by researchers from the Barcelona Institute for Global Health (ISGlobal), a centre supported by 'la Caixa,' has identified a key biological mechanism that puts men at higher risk of cancer: loss of function in certain genes of the sex-determining Y chromosome, which is present only in men.

Timely prediction may help prevent the condition using nutritional and lifestyle changes.

Studies of animal movement and behavior--including those addressing disease spread and animal conservation--should monitor animals at both regular and irregular time points to improve understanding of animal movement behavior, according to a new study by Penn State statisticians. The study is the first to provide guidance about sampling regimes for this type of biological research.

In a new study published in the advanced online edition of Molecular Biology and Evolution, scientists Alexandre Gouy and Laurent Excoffier have developed new computational tools to better analyze human genome datasets, and found more evidence of a legacy of ancient hominid adaptation, particularly to help fight off infectious diseases like malaria.

A dMRI study suggested that structural strengthening of connections involving subcortical regions associated with pain processing and weakening in connections involving cortical regions associated with hyperexcitability may coexist in migraine. Also, migraine attacks may impose plastic adaptations in the brain.
