Nature research paper: Mitochondrial fission factor senses and governs ferroptosis go.nature.com/46thBrP
Mitochondrial fission factor senses and governs ferroptosis - Nature
The mitochondrial–peroxisomal fission adaptor MFF is identified as a selective pro-ferroptotic mediator, and the newly developed MFF–SPARK sensor enables high-content screening of ferroptosis-sensitizing compounds and the discovery of upstream regulators of MFF.

For the first time, researchers have restored some vision to people with a common eye disease by using a prosthetic retinal implant. The treatment could improve the lives of an estimated one million people in the U.S. who lose their vision to the condition if it's approved for broader use.
