Protecting Sight #241: A concrete idea to reduce carbon emissions. Fibrotic lens capsule, loose zonules, CTRs, and capsular retractors. A white macula post-PPV. Happy #NationalPizzaDay!

Welcome to my daily learning journal. My daily goal is to watch one Ted Talk and one cataract surgery. I also plan to read one journal article and read/listen to a book chapter, podcast, or significant work.

Here is today’s list:

1. Ted Talk – Karen Scrivener: A concrete idea to reduce carbon emissions. “Concrete is the second most-used substance on Earth (behind water), and it’s responsible for eight percent of the world’s carbon footprint. Cement researcher Karen Scrivener shares the research behind a pioneering new kind of cement known as LC3, which could slash carbon emissions from this crucial building material by 40 percent, if adopted at scale.” (

Love these innovations to reduce carbon emissions in the years ahead.
