When the scientists mixed the two vesicles, they observed that the ones with sucrose in which there was greater membrane tension did, indeed, grow by...DHA-rich diet protects brain from Alzheimer's damage, UCLA study shows
...epleted diet," observed Frautschy. "These changes closely resembled those we see in the brains of people with Alzheimer's disease." Although the mice on the DHA-supplemented diet also carried the Alzheimer's genes, they still performed much better in memory testing than the mice in the first group.

...one explanation for why humans and primates are so closely related genetically, but so clearly different biologically and intellectually. It is an established fact that 98 percent of the DNA, or the code of life, is exactly the same between humans and chimpanzees.
