Description
Maddelyn Harden watches heat stress break the inner parts of giant kelp cells that make new kelp. Forests of this kelp are in steep decline as seas warm. The 2026 study hones sharp imaging tools for the tiny sex stage of Macrocystis pyrifera, the phase that seeds each new forest. Cells from tough and weak strains face a range of heat loads.
Stressed cells showed green food-making parts drift out of place, crack apart, and then fade away. Cell cores broke up and lost their glow step by step. Germs that live with the cells grew fast in the heat. In brown algae, core and green parts share one outer skin, which may be why both fail at once. Tough strains showed far fewer flaws than weak strains at the same heat.
