accumulate

When heated, the base layers accumulate thermal radiation, which can be thought of as a bath of photons.

Where do plastics accumulate in the environment?

"We now know that plastics contain roughly 16,000 chemicals. Of these, it is known that over 4,200 are persistent in the environment, accumulate in living organisms, are transported over long distances or pose a potential hazard," says Annika Jahnke.

"While harmless on their own, these changes could be the basic building blocks of breast cancer. With further research into how these mutations arise and accumulate, we could potentially develop new and lifesaving preventive strategies, therapeutic approaches, and routes for early detection."

The researchers say the study raises important new questions about the nature of breast cancer development, including how mutations accumulate and over what timescale, and why the mutations only occur in luminal cells.
