Evaluating Evolutionary Rates Could Shed Light Into Functions of Uncharacterized Genes
February 8, 2013 — Genes that have roles in the same biological pathways change their rate of evolution in parallel, a finding that could be used to discover their functions, said a researcher. Humans have nearly ... > full story -
Nucleus Structure Crucial to Understanding Diseases Discovered
February 8, 2013 — Scientists from Singapore and Germany have identified that the proteins lamin A and lamin B receptor are essential for holding silent genes in their correct position at the edge of the nucleus, in ... > full story -
Histone Modification Controls Development: Chemical Tags on Histones Regulate Gene Activity
February 8, 2013 — Every gene in the nucleus of an animal or plant cell is packaged into a beads-on-a-string like structure called nucleosomes: the DNA of the gene forms the string and a complex of proteins called ... > full story -
Protein Paves the Way for Correct Stem Cell Differentiation
February 7, 2013 — A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated. New research has ... > full story -

Translation Error Tracked in the Brain of Dementia Patients: Scientists Identify Enigmatic Aggregates Linked to Neurodegenerative Diseases
February 7, 2013 — In certain dementias silent areas of the genetic code are translated into highly unusual proteins by mistake. The proteins that have now been identified shouldn't actually ... > full story -
Sugar Influences the Onset of Flowering: Only When Light, Age and Energy Conditions Are Right Do Plants Flower
February 7, 2013 — Only when light, age and energy conditions are right do plants flower. A plant can reproduce successfully only if it flowers at the appropriate time. Therefore, a complex network of photoreceptors ... > full story -
Cells Forged from Human Skin Show Promise in Treating Multiple Sclerosis, Myelin Disorders
February 7, 2013 — Human brain cells created by reprogramming skin cells are highly effective in treating myelin disorders, a family of diseases that includes multiple sclerosis and rare childhood disorders called ... > full story -
Study Identifies Liver Gene That Regulates Cholesterol and Fat Blood Levels
February 7, 2013 — Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in ... > full story
