A community leads protection of the pangolin in a critical illegal trade corridor

In Nagaland’s Kiphire district, along the porous Indo-Myanmar border, pangolins have been hunted for decades — once due to cultural beliefs, and increasingly for trade, in a region identified as a key wildlife trafficking route.

“Our forefathers would say that if a pangolin enters a house, it was considered a bad omen or curse,” says L. Kipitong Sangtam, 61, a resident of Amahator village in Kiphire district. “In the past, if someone encountered a pangolin, they would try to catch and kill it,...

This Fish Glows By Stealing Light From Its Prey – Asian Scientist Magazine

AsianScientist (Apr. 29, 2026)– In the natural world, animals usually rely on their own genes to produce the traits they need to survive. These genes act like instruction manuals, telling the body how to make important molecules, including proteins that perform specific functions.
Researchers from Tohoku University in Japan have now found an exception: the golden sweeper (Parapriacanthus ransonneti), a schooling reef fish. They discovered that the fish can glow in the dark, not by making its own...

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...
