Alzheimer's Disease and Glutathione (GSH)

A new study indicates the possibility to monitor the progression of Alzheimer's disease by monitoring glutathione (GSH)

In a breakthrough human study, anti-oxidant, glutathione (GSH), which protects the brain from stress, has been found to be significantly depleted in Alzheimer's patients compared to normal subjects. As GSH is a very important anti-oxidant that protects the brain from free radicals, the findings give us another measure to use when diagnosing potential for the advancement of Alzheimer's disease or recognizing those that are in the throes of Alzheimer's advancement.

-  Note: Glutathione is one of the body's major antioxidants, and is found to be deficient in pateints with cardiac problems.  It is also marketted as an important health supplement.

Tracking the movement of the tropics 800 years into the past

Tracking the movement of the tropics 800 years into the past

For the first time, scientists have traced the north-south shifts of the northern-most edge of the tropics back 800 years. The movement of the tropical boundary affects the locations of Northern Hemisphere deserts including the Sonoran, Mohave and Saharan. The Earth's climate system affects the movement of the tropics, which have been expanding since the 1970s. The research team found that in the past, periods of tropical expansion coincided with severe droughts.
