Macquarie University researchers discovered that honeybee stingers continue delivering venom after detaching from the insect. High-speed video analysis reveals tiny valves act as collapsible pistons to drive a continuous flow of venom into victims.
Scientific American reports on a study published in Science identifying "saprotropism," a new plant movement where roots bend away from decaying tissue. Researchers discovered this behavior accidentally, noting Arabidopsis thaliana roots avoided rotting apple patches, suggesting plants actively evade harmful microbial environments.
This review of Jonathan Silvertown's 'Nature's Magicians' explores the evolutionary significance and ecological functions of leaves. The author contends that the book successfully demystifies leaf biology, highlighting their critical role in oxygen production, carbon sequestration, and soil fertility.
The Indian Express explains how tiger stripes provide camouflage by breaking up the animal's outline against vegetation. Citing wildlife photographer Indrajit Ghorpade, the piece notes that prey animals' dichromatic vision makes orange tigers less conspicuous than to humans, aiding hunting success.
