| New insight in how cells' powerhouse divides Posted: 02 Sep 2011 10:31 AM PDT New research puts an unexpected twist on how mitochondria, the energy-generating structures within cells, divide. The work could have implications for a wide range of diseases and conditions.  |
| How 'railways' within cells are built in order to transport essential cargos Posted: 02 Sep 2011 08:02 AM PDT Every cell in the human body contains a complex system to transport critical material such as proteins and membrane vesicles from one point to another. Researchers have now come one step closer to understanding the elusive mechanics of this process.  |
| Growth hormone helps repair the zebrafish ear Posted: 02 Sep 2011 05:37 AM PDT Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible. However, both birds and fish are able to re-grow the damaged hair cells and restore hearing. New research shows that growth hormone is involved in this regeneration in zebrafish.  |
