Alzheimer's disease is not accelerated aging
...s, and functional imaging methods such as positron emission tomography (PET) and functional MRI in healthy adults and individuals with Alzheimer's disease, as well as new techniques that enable imaging of amyloid plaques in people living with Alzheimer's. Together, these point toward a disrupted network in th...Natural mineral locks up carbon dioxide
...Because carbon dioxide will be the last gas in the emission stream treated, there are two options for commercial implementation. Fossil fuel burning plants could simply place a serpentine reactor as the last component of their emissions clean up and sequester carbon on site.
