Addition of longer wavelength absorbing chlorophylls into crops could increase their photosynthetic productivity by 26% - Nature Communications

Incorporation of the far-red light adaptation of cyanobacteria into crops has been suggested as a potential strategy to increase photosynthesis and yields, but the magnitude of this benefits has not b...

A chlorophyll fluorescence-based biofeedback system was developed to adjust LED intensity based on real-time plant responses, rather than using a fixed photosynthetic photon flux density (PPFD). The system was tested in a growth chamber with lettuce and cucumber.

Looks like burdock to me. I think that the 1) hooked burrs can cause discomfort if they get entangled in fur & 2) burdock contain lactones which can cause dermatitis on skin/or irritate digestion if eaten. But personally I would not consider it toxic

“I spend so much time on TikTok,” she said. “Hours and hours, until my eyes start hurting, which makes it hard to plan and do my schoolwork. With ChatGPT, I can write an essay in two hours that normally takes 12.”

"No work, no play" sounds like an incredibly rewarding college experience.
