New understanding of physical properties of chromatin may show how genome is encoded and decoded

University of Alberta researchers have found an answer to a fundamental question in genomic biology that has eluded scientists since the discovery of DNA: Within the nucleus of our cells, is the complex package of DNA and proteins called chromatin a solid or a liquid?

Mother's diet while breastfeeding can shape the profile of human milk oligosaccharides

Research has shown that human milk is the optimal nutrition source for neonates and infants. It confers protection against both immediately life-threatening infant diseases such as necrotizing enterocolitis, as well as later onset diseases in adults, like obesity, diabetes and inflammatory bowel disease.
