That Fresh-Cut Grass Smell? It’s a Plant’s Distress Call – Asian Scientist Magazine

AsianScientist (Apr. 13, 2026)–That fresh, sharp scent released when grass is cut is often associated with calm and nostalgia, but beneath this sensory experience lies a sophisticated biological signal. These compounds, known as green leaf volatiles (GLVs), are released by plants within seconds of being wounded, attacked by herbivores, or exposed to environmental stress.
GLVs are active participants in plant defense. They suppress pathogens, warn neighbouring plants to prepare for attack, and at...

What wild poop can teach children about ecology [Book review]

For human beings, the topic of excreta is considered a subject of disgust and embarrassment. The Big Book of Wild Poop, written by Shweta Taneja, sets out to change the narrative of how humans, children in particular, view poop. In the animal world, excreta is not waste but information, food, camouflage and defence, the book says. For a dung beetle or a worm, it is a source of multivitamins. Some spiders disguise themselves with it to escape predators, while hoopoe mothers use it to protect thei...
