Farmers might be able to get help tending and harvesting crops using a new sensing technology from Carnegie Mellon University's Robotics Institute (RI). Researchers have invented a tool called SonicBoom that can find crops like apples based on the sound they make. The novel technology, still in the early stages of development, may someday be used by farm robots for tasks like pruning vines or locating ripe apples hidden among the leaves. /news/2025-08-agricultural-sensor-crops-vibrations-alternative.html Biotechnology Agriculture Thu, 14 Aug 2025 16:23:04 EDT news674407382 In the selection of specialty coffees, those that score above 80 points in blind tests are free of physical and sensory defects. Greenish-colored beans are known to give the drink an astringent taste, which is described as harsh, pungent, and dry. These beans are therefore discarded, along with broken, black, burnt, pitted, or undersized beans. /news/2025-08-fermentation-unripe-coffee-beans-high.html Biotechnology Agriculture Wed, 13 Aug 2025 16:45:04 EDT news674322301 Just as overlapping ripples on a pond can amplify or cancel each other out, waves of many kinds—including light, sound and atomic vibrations—can interfere with one another.
