They are the most common repeated elements in the human genome; more than a million copies are scattered among and between our genes. Called Alu elements, these relatively short, non-coding sequences of DNA cause genomic structural variation. Now scientists have developed a novel computational tool that predicts genomic instability that can lead to disease. Source: […]

Bioengineers have demonstrated that a gel-like material containing tiny magnetic particles could be used to manage chronic pain from disease or injury. Broadly, the study demonstrates the promising use of biomechanical forces that push and pull on cells to treat disease. Source: Bioengineers use magnetic force to manage pain

Medical researchers have found a lower prevalence of overweight and obesity among youth in Grenada compared to US adolescents. The differences may reflect the impact of the westernized diet and lifestyle. The research may lead to a change in worldwide obesity prevention strategy.
