Understanding such force distributions is crucial for the prediction of the failure condition of these materials. This study shows that the force distributions can be accurate...Researchers compare chicken, human genomes
...fferences between human and chicken genes were not uniform across the board, however. Chicken genes involved in the cell's basic structure and function showed more sequence similarity with human genes than did those implicated in reproduction, immune response and adaptation to the environment.
