Pitch-dark lab, one cell, a few photons a second — would you bet a diagnosis on that? Sardarabadi Hadi et al. (2023) review ways to boost BAL. But boost what? No full spectrum exists; the dominant emitter is unproven. How would you amplify the glow without rewriting the chemistry? #biophotons

Your cells glow because oxygen bites back. ROS chew on lipids → peroxyl radicals pair up → collapse into triplet carbonyls → flash! Photons from UVA to IR (Pospíšil et al. 2014). But which ROS runs the show in living tissue? Unproven. What quencher would you test first? #biophotons #Science

1923: an onion root, a quartz window, and Gurwitsch claiming cells beam UV at each other. Bold — but his 'detector' was cell division itself: circular. PMTs later proved the glow (Colli 1954; Popp coined 'biophoton'). da Nóbrega (2006) retells it. Who's your underrated pioneer? #biophotons #Science

Picture a cell whispering single photons in a pitch-black box. How do you count that? Kobayashi (2003) reviews Inaba's detector craft: chilled PMTs, single-photon counting. Caveat: at ~10 photons/s/cm², dark counts can fake your signal. What's your dark-count protocol? #biophotons #Science

Imagine counting single fireflies in a storm — your net decides what you catch. Mould et al. (2024): EMCCDs hit >90% efficiency, yet random gain lets one photon masquerade as two. PMTs stay gold standard; SPADs drown in dark counts. What do you trust for UPE? #biophotons #UPE #Science

"Biophotons are coherent like a laser" — Han et al. (2014). Their evidence? A flat spectrum instead of Boltzmann. But spectral shape ≠ coherence. No g(2), no interferometry, no photon-counting stats. Show me second-order correlations — then we talk lasers. #biophotons #Science

Your fingertip glows in the dark — a rainbow too faint to see. The catch: it takes heavy background subtraction to extract. Kobayashi et al. (2016) split human skin UPE into bands: blue-green ~ triplet carbonyls, red ~ singlet O2. Which band would you trust most? #biophotons #UPE #Science

Cifra (2011) traces how Gurwitsch's "mitogenetic radiation" — detected via onion root division — was confirmed by Colli's PMTs in 1954. The biology was real; the proof was circular. Old careful biophysics deserves respect. #Biophotons #HistoryOfScience #Science

Photon stats don’t need fancy gear. Martínez et al. (2007) used a digital oscilloscope to catch single photons—proving modest kit works if you respect the noise floor. Solid: clean counting logic. Not: classroom scope, not real-world UPE. What’s your dark-count protocol? #Biophotons #Physics
