Vegan diet can halve your carbon footprint, study shows
FrontiersPeer-Reviewed Publication
Researchers from University of Granada and the Spanish National Research Council designed four ideal weekly menus with an equal energy value and following international recommendations for the daily intake of a wide range of macro- and micronutrients. Each menu was in accordance with an omnivorous Mediterranean, pesco-vegetarian, ovo-lacto-vegetarian, or vegan diet. The vegan diet reduced carbon emissions by 46%, water use by 7%, and land use by 33%, while the two vegetarian diets cut carbon emissions by up to 35%. The three plant-based diets were nutritionally balanced, except for small deficits in vitamin D, iodine, and vitamin B12, which can be remedied with supplements. The authors concluded that plant-based diets are equally nutritious and healthy as a Mediterranean diet, and much better for the planet.

Photon avalanche nanomaterials: from spark to surge
Chinese Society for Optical EngineeringPeer-Reviewed Publication
Photon avalanche (PA) upconversion, driven by a positive feedback loop that couples nonresonant ground-state absorption (GSA), resonant excited-state absorption (ESA), and highly efficient cross-relaxation (CR), gives rise to a threshold-triggered ultrahigh optical nonlinearity accompanied by uniquely prolonged rise-time dynamics. From spark to surge, this phenomenon can deliver tens to even hundreds of nonlinear orders at the nanoscale, redefining opportunities in imaging, sensing, and optical computing while opening a new paradigm for interrogating light–matter interactions.

Harnessing algae for a greener way to create functional gold nanoparticles
The University of OsakaPeer-Reviewed Publication
Researchers have developed an eco-friendly method to create gold nanoparticles (AuNPs) using microalgae. This "green synthesis" avoids harsh chemicals, resulting in nanoparticles that are more stable than conventional ones. When activated by a laser, these AuNPs effectively destroy cancer cells while showing lower toxicity to healthy cells. This breakthrough promises a more sustainable and safer approach to photothermal cancer therapy and other applications in nanomedicine.
