Calgary researchers discover that life has a literal glow

Researchers at the University of Calgary have discovered that living organisms, including mice and plants, emit weak light as part of their metabolism, which is detectable with specialized cameras. In a study published in the Journal of Physical Chemistry Letters, they found that living mice emit more photons than dead ones, suggesting a link between life and light emission. The research may lead to non-invasive methods for assessing the health of plants and human tissues, although the exact biochemical processes behind this phenomenon are still not fully understood.
