- A new Nature Scientific Reports paper (https://www.nature.com/articles/s41598-025-09785-3) claims that longer-wavelength sunlight (≈850 nm) penetrates human tissue, boosts mitochondrial membrane potential and ATP production, and measurably improves vision—especially when mitochondrial function has declined with age or disease.  
- Participants noted that 850 nm LEDs are now “super cheap,” making DIY photobiomodulation experiments feasible, although recent U.S. tariffs may raise prices.  
- Eli summarized the proposed mechanism: red/NIR light activates cytochrome c oxidase in mitochondria, increasing ATP; because the approach is hard to patent, large-scale clinical trials are scarce.  
- Eli plans to contact an Austin-based practitioner at OvalBio who combines LED photobiomodulation with hyperbaric oxygen therapy (HBOT) and has offered free sessions for data collection; results may be reported back to the channel.
