New research shows that creatures emit faint light that destroys death
Credit: Journal of Physical Chemistry Letters (2025). doi:10.1021/acs.jpclett.4c03546 The light in someone else’s life may not be just another person, but in the literal sense of light. According to a recent study by researchers at the University of Calgary, all living systems emit light without the need for external excitation due to a biological phenomenon known as ultraweek photon emission…

Switchable singlet fission: pH triggers molecules to split or emit light from the sensor
Designing our work by fusing tetracendimers and pyridyl end groups. Credit: Natural Communication (2025). doi:10.1038/s41467-025-58168-9 An international team of researchers managed to control the flow of molecules’ energy with the help of their pH values. The results of this study, led by Friedrich Alexander Universitat Erlangen Nurnberg (FAU), could, for example, contribute to the development of new sensors for medical…

Oceans emit sulfur, cooling the climate more than previously thought
Scientists have successfully quantified methanethiol emissions in the oceans on a global scale for the first time. Credit: Rafel Simó (ICM-CSIC) Researchers have for the first time quantified global emissions of sulfur gas produced by marine life, revealing that sulfur gas is cooling the climate more than previously thought, especially in the Southern Ocean. The study, published in the journal…
