Researchers create a new window on leading genetic cause of Alzheimer’s

Scientists have detected over 300 proteins associated with lipoproteins in the central nervous system, far more than previously thought. The most common protein, apolipoprotein E (APOE), plays a key role in delivering nutrient-rich lipids and protein tools to perform tasks such as wound healing and neuron creation.

Fall snow levels can predict a season's total snowpack in some western states

Researchers found that fall snow levels are a good predictor of total snowpack in some western states, particularly in northern regions like Alaska, Oregon, and Washington. This prediction works due to cooler air temperatures and weather patterns that help retain snow on the ground, adding to the total snowpack.
