The Light of Life? We actually do glow till our Death, study finds by Sayan Sen Image by Rafael Rendon via Pexels A study by researchers at the University of Calgary has found that living organisms produce an extremely faint light known as ultraweak photon emission, and that this glow appears to drop significantly after death. The research was published in the Journal of Physical Chemistry in April 2025 and quickly drew widespread attention, leading to more than 200 news stories about the findings. Ultraweak photon emission (or UPE), sometimes called biophoton emission, refers to tiny amounts of light released by living cells as a result of normal biological activity. A photon is the basic particle of light, and researchers say every living system examined so far, including plants and animals, has been found to emit these photons. The glow is far too faint to be seen by the human eye. “I suppose it has a little to do with people being reminded of auras,” says Dr. Christoph Simon, PhD, one of the authors of the study and a professor in the Department of Physics and Astronomy in the Faculty of Science. “It is a fact that living beings glow. It’s a very weak glow, but it’s there and visible with very sensitive cameras.” According to the study, the light involved is extremely weak, ranging from 10 to 1,000 photons per square centimetre per second across a spectral range of 200 to 1,000 nanometres. For comparison, a nanometre is one-billionth of a metre and is commonly used to measure wavelengths of light. Detecting emissions at such low levels requires highly specialized equipment. To study the phenomenon, researchers used electron-multiplying charge-coupled device (EMCCD) and charge-coupled device (CCD) cameras. These imaging systems are designed to detect extremely small amounts of light, including individual photons, while minimizing background noise. The technology allowed researchers to capture signals that would otherwise be impossible to observe. The team worked with the Human Health Therapeutics Research Centre at the National Research Council of Canada (NRC) in Ottawa to examine photon emissions in mice. Researchers took two-hour exposure images of the animals before and after death and compared the results. “We saw that the level of light that they emit – this biophoton glow – is distinctly different between living and dead animals,” says Dr. Daniel Oblak, PhD, an associate professor in Physics and Astronomy and the corresponding author of the study. The images showed a clear decrease in photon emissions after death across the entire body of each mouse. According to the researchers, this provided direct evidence that living and dead tissue produce different levels of ultraweak photon emission. “It’s a very small amount and it’s, of course, very tricky to detect,” Oblak says. The study grew out of discussions between Simon, whose research interests include quantum biology, and Oblak, whose work focuses on detecting light for quantum communication experiments. Quantum biology is a field that explores whether processes described by quantum physics, which studies matter and energy at very small scales, may also play a role in living systems. “Since I work as a quantum physicist on light detection for quantum communication, I thought that experimentally we have a lot of the tools to be able to detect the light,” Oblak explains. The researchers also investigated UPE in plants and found that the light changed in response to stress. When plants were exposed to higher temperatures or physically injured, their photon emissions increased. Chemical treatments also affected the glow. Among the substances tested, the local anesthetic benzocaine produced the strongest emission response when applied to injured plant tissue. These findings suggest that ultraweak photon emission is closely linked to biochemical and metabolic activity inside living organisms. Metabolism refers to the chemical reactions that allow cells and organisms to stay alive and function. Because these reactions change when an organism experiences stress, injury or disease, researchers believe UPE may provide a way to monitor those changes. The researchers stress that the glow is a physical and biological phenomenon, not a metaphysical one. Oblak says more research is needed to understand exactly how the light is produced and what information it may reveal about the condition of living tissue. “We must understand what that is to figure out what’s happening,” he says. “If we can understand how that relates to certain influences on the body – stress, diseases – then that could be used as a diagnostic tool.” The researchers believe the technique could eventually help scientists study health and disease without invasive procedures. Because UPE can be measured without adding dyes, markers or labels, it may offer a way to monitor whether tissue is healthy, damaged or alive. In plants, it could help researchers better understand how organisms respond to injury, heat and other forms of stress. While the work is still in its early stages, the study demonstrates that ultraweak photon emission imaging can provide a non-invasive and label-free way to observe biological activity. Researchers say the approach could become a useful tool for studying vitality, stress responses and other important processes in both animals and plants.

Rufus 4.15.2393 Beta 2 by Razvan Serea Rufus is a small utility that helps format and create bootable USB flash drives, such as USB keys/pendrives, memory sticks, etc. Despite its small size, Rufus provides everything you need! Oh, and Rufus is fast. For instance it's about twice as fast as UNetbootin, Universal USB Installer or Windows 7 USB download tool, on the creation of a Windows 7 USB installation drive from an ISO (with honorable mention to WiNToBootic for managing to keep up). It is also marginally faster on the creation of Linux bootable USBs from ISOs. A non-exhaustive list of Rufus supported ISOs is available here. It can be especially useful for cases where: you need to create USB installation media from bootable ISOs (Windows, Linux, UEFI, etc.) you need to work on a system that doesn't have an OS installed you need to flash a BIOS or other firmware from DOS you want to run a low-level utility Rufus 4.15.2393 Beta 2 changelog: Add RISC-V 64 support to UEFI:NTFS Improve the guards for using the "silent" option Improve the ability to cancel during write retries Improve progress reporting for compressed image extraction Fix unrestricted XML entity expansion and integer overflow in ezxml parser (courtesy of @esadowski4) [GHSA-55r2-34wg-8mv9] Fix "silent" Windows installation failing at 75% in most cases [#2960] Fix a crash during boot when using UEFI:NTFS on Snapdragon X based ARM64 platforms [#2934] Fix the first WUE option always being checked by default [#2965] Fix an infinite loop when using Windows ISOs that contain multiple WIMs Fix "Enable runtime UEFI media validation" checkbox not always being properly enabled Other WUE improvements/fixes for OneDrive removal and username validation (with thanks to @christian8641) [#2984, #2991] Download: Rufus 4.15 Beta 2 | 1.9 MB (Open Source) Links: Rufus Home Page | Project Page @GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
