  • Researchers develop first human model for studying the neuronal pathology of Leigh syndrome
    Leigh syndrome is the most severe mitochondrial disease in children. It causes severe muscle weakness, movement defects, and intellectual disabilities. It usually leads to death within the first years of life. No causative treatment is currently available. One of the genes frequently mutated in patients is SURF1, which encodes for a protein involved in the process of energy generation in the cells.

  • Study links genes with function across the human brain
    Many psychiatric disorders have genetic causes, but the exact mechanism of how genes influence higher brain function remains a mystery. A new study provides a map linking the genetic signature of functions across the human brain, a tool that may provide new targets for future treatments.

  • New method uses DNA biomarkers to flag prenatal environmental exposures in children
    Scientists at Columbia University Mailman School of Public Health developed a method using a DNA biomarker to easily screen pregnant women for harmful prenatal environmental contaminants like air pollution linked to childhood illness and developmental disorders. This approach has the potential to prevent childhood developmental disorders and chronic illness through the early identification of children at risk.

  • New, highly precise 'clock' can measure biological age
    Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an 'aging clock' that reads the biological age of an organism directly from its gene expression, the transcriptome. Bioinformatician David Meyer and geneticist Professor Dr Björn Schumacher, director of the Institute for Genome Stability in Aging and Disease at the CECAD Cluster of Excellence in Aging Research and the Center for Molecular Medicine Cologne (CMMC), describe their so-called BiT age (binarized transcriptomic aging clock) in the article 'BiT age: A transcriptome based aging clock near the theoretical limit of accuracy' in Aging Cell.

  • Genes identified that increase the risk of obesity but also protect against disease
    People living with obesity tend to have unhealthy glucose and lipid levels in their blood, as well as high blood pressure. As a result, they are more at risk of cardiovascular and metabolic diseases. But scientists have observed that up to 45% of people living with obesity have healthy blood pressure and glucose and lipid levels, and therefore may not be at high risk of disease. The reason why this group of people with obesity remain healthy, has been poorly understood.

  • How a gene called HAND2 may impact the timing of labor
    A new study illuminates how a gene called HAND2 may have a hand in the timing of human labor.
