accumulation

In contrast, participants who were largely inactive showed faster accumulation of tau proteins in the brain, which is associated with Alzheimer's progression, and more rapid declines in thinking skills and daily functioning.

"However, it is important to proceed with caution. SEL1L also plays a crucial role in preventing the accumulation of damaged proteins, which is essential for long-term cellular health."

"Ultimately, we hope to learn how to optimize the circadian system to prevent amyloid accumulation and other aspects of Alzheimer's disease."

"This study supports the idea that, rather than direct adaptation, genome size in these species depends primarily on a balance between the accumulation and removal of this repetitive DNA," the researchers conclude.

But Water UK called for a ban on the chemicals to prevent accumulation.
