Alzheimer's plaques found in dolphins' brains hint at toxin risk

In a new study, researchers revealed the discovery of beta-amyloid plaques in the brains of stranded dolphins, the same plaques associated with Alzheimer’s disease in humans. The finding builds upon existing evidence of an association between toxic cyanobacterial blooms and Alzheimer’s risk, though there’s still not enough evidence to determine whether this toxin puts humans at risk. Past research identified …
