Type 1 diabetes, also referred to “juvenile diabetes” due to the typically early development of the disease, is caused when pancreatic cells that produce insulin are attacked by the body, thus decreasing the individual’s ability to produce insulin without medication. Recently, the rates of type 1 diabetes have been on the rise within the U.S. and scientists are searching to understand why this is the case. German-based scientist, Ezio Bonifacio, has been studying children after birth with a predisposed genetic history of diabetes.

Recent studies are being performed to improve and restore hearing of mice lacking the gene required for hearing. The experiment utilizes gene therapy to target the inner ear hair cells, which send neural inputs of balance and hearing. Scientists used a combination of a virus gene-carrier, adeno-associated virus (AAV), and exosomes, a protective cellular “bubble,” as a vehicle for the gene therapy. This combined method was found to allow the gene to bind to the hair more effectively, compared to using only AAV. The findings showed that nine of the twelve mice treated with this form of gene-therapy saw improvement in hearing and balance. While this study is ongoing, it will be years before the experiment is tested on human subjects.
A recent article published in Science Magazine is providing evidence that air pollution contributes to the development of Alzheimer’s Disease. While it has been established that air pollution plays a role in lung cancer and asthma, new studies are showing the neurological impact with dementia and Alzheimer’s development.
