Now scientists from Harvard Medical School have developed a way to increase the predictive accuracy of genetic mutations as forerunners of diseases that may develop down the road. Using large-scale genomic analysis, the team has succeeded in illuminating patterns that can help predict symptoms likely to be caused by poorly
September 12, 2017 Brain scientists have identified a genetic programme that controls the way our brain changes throughout life. The programme controls how and when brain genes are expressed at different times in a person's life to perform a range of functions, the study found. Experts say the timing is so precise that they can tell the age of a person by looking at the genes that are expressed in a sample of brain tissue. Scientists analysed existing data which measured gene expression in brain tissue samples from across the human lifespan - from development in the womb up to 78 years of age. They found the timing of when different genes are expressed follows a strict pattern across the lifespan.
