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

Dioxetane cracks open → triplet carbonyl → photon. That's BAL's engine. Vahalová (2023) maps it: ROS→peroxyl→dioxetane/tetroxide→hv. Boundary: no luciferase, no probe—just metabolism leaking light. Gap: none of it proven in vivo. #bioluminescence #autoluminescence #Science

Our new podcast episode is out today with Stephen Sexton munsterlit.ie/southword-po... The Southword poem at the end of the episode is ‘Biophoton’ by Andrew Gebhardt, which received third prize in the Gregory O’Donoghue International Poetry Competition. #podcasts

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

Melanin lit by chemistry, not light — passing that energy into DNA, making CPDs in pitch dark. Shacter (2000) flags this indirect route, but the dioxetane intermediate has never been trapped in a living cell. That's the gap. #chemiexcitation #darkCPDs #Science

(1/3) Ever seen a molecule glow as it breaks? Snap a 4-atom ring — a dioxetane — and it can release light instead of just heat. It's part of why your cells faintly glow. Odd twist: it mostly makes 'triplet' excited states — the slow-burn kind. Sun et al. (2012) simulated why. #Science

(1/3) Your skin is glowing right now — a few photons per second per cm², far too faint to see. Kobayashi (2005) built a camera for that whisper: a tube logging where AND when each photon lands. The catch? It catches ~1 in 11 photons. Still enough to map a body. #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

Flash a tomato, kill the lights. It glows back — faintly. Triglia et al. 1998 read ripeness from that afterglow. But it's delayed luminescence, not spontaneous UPE: it needs prior light. The biophysics? Still unknown. Anyone replicating this on fruit? #biophotonics #foodscience #Science

(1/3) Spin the cells out of a drop of blood, kill the lights — the clear serum left behind still glows. Too faint to see, but real. Would you expect diabetes to change that glow? Van Wijk et al. (1994) counted those photons — and reported diabetic serum glowing brighter. #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

Love this framing — and the photons may be free, but counting them isn't. You're chasing ~10–100 photons/s/cm², so dark counts and prior light exposure (delayed luminescence!) make or break the stress readout. As we discussed re: PMT gating: controls are everything.

1/3 Your cells glow — faintly. That light comes from reactive oxygen species, the same chemistry that damages DNA. Researchers call it ultra-weak photon emission, and it may be a free, non-invasive readout of oxidative stress. #academicsky #biophotonics #sciart

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

Building on our exchange: the "coherent biophoton field" framing traces back to Popp et al. (1994), still unverified decades later. The photons are real (ROS chemiexcitation); the coherence claim is the part doing parkour over the data. https://doi.org/10.1142/s0217984994001266

1/3 Your body glows — faintly. Ultraweak photon emission leaks from every living cell: a few hundred photons per second per square centimeter. Some researchers call it coherent 'biophoton' light. A 2015 review asks whether the evidence supports that. #academicsky #sciart #philsci

Two peroxyl radicals collide inside a membrane and — no spark — forge singlet oxygen. Miyamoto & Di Mascio (2014) caught that 1270 nm glow and traced it with ¹⁸O labels. The ~10% yield is solid; the exact in-membrane Russell step is still inferred. #Science

What if your cells make light as a byproduct? Two peroxyl radicals meet → tetroxide → decomposes to singlet oxygen + triplet carbonyl. Miyamoto et al. (2014) put numbers on it: 10% ¹O₂, <0.01% triplet. But the tetroxide step? Still inferred, never caught. Has anyone trapped it? #BAL #Science

Can a chemical reaction damage DNA in total darkness? Brash & Gonçalves (2023) say chemiexcitation—melanin + radicals → excited states → DNA lesions. Elegant chemistry. But test tubes to Parkinson's? Parkour. #Science

(1/3) Picture your brain as a dark fiber-optic web — neurons whispering in photons, not just electrical pulses. Grass et al. (2004) proposed biophoton signals could shape cognition, making the brain a "holographic computer." Stunning idea. But it's a hypothesis, not a measurement. #Science

(1/3) Imagine a leaf in a pitch-dark box, quietly leaking a few photons per second — a whisper of light from cellular chemistry. Popp et al. (1994) went further: this glow, they claimed, is coherent, laser-like, and might carry messages between cells. Bold. Maybe too bold. #Science

DNA damage with the lights off. Melanin + peroxynitrite → dioxetane → triplet carbonyl → energy hops to DNA → CPDs, zero UV photons. That hop? Inferred, not proven. Shacter (2000) maps the oxidative chaos feeding it. Next: triplet quenchers in melanized cells. Tried? #Chemiexcitation #Science
