Scientists at the Weizmann Institute discovered that mice use their whiskers to produce ultrasonic sounds for echolocation, allowing them to navigate and identify objects in complete darkness, revealing a sophisticated biological sonar system that could inspire new human technologies.
Plants make ultrasonic popping sounds when they are distressed, according to a study by researchers at Tel Aviv University. The sounds are inaudible to humans but may be a call for help. The researchers found that plants emit noises when they are cut, dehydrated or infected. The sounds are produced by air bubbles in the plant's xylem tissue, which moves water. The researchers hope their findings will help farmers identify when their plants need water or are infected. They also plan to investigate whether damaged plants communicate with animals and other plants.
A new study from Tel Aviv University found that plants emit specific sounds when under stress, which can be detected by ultrasonic microphones. The sounds are too high for humans to hear, but can be heard by animals such as bats, mice, and insects. The study found that stressed plants emit dozens of sounds every hour, while unstressed plants emit less than one sound per hour. This discovery could prove beneficial in the agriculture industry, as more precise irrigation can save up to 50% of water expenditure and increase yield.
Plants emit ultrasonic sounds when they are thirsty or stressed, according to a study by Tel Aviv University scientists. The researchers used microphones to record the sounds produced by tomato and tobacco plants in a sound-protected box and a greenhouse. They developed machine learning models to identify the condition of the plants based on the detected sounds. The study suggests that humans could use this information to determine when plants need watering. However, scientists caution that there is no evidence that the sounds produced by plants are a form of communication.
Israeli scientists from Tel Aviv University have recorded airborne sounds from stressed plants for the first time and classified them. The study found that different species of plants speak in different "languages" and emit sounds at high frequencies beyond the hearing range of humans. The researchers believe that the sounds contain information about water scarcity or injury and could be utilized by humans with the right tools, such as sensors for precision agriculture. The findings could also have implications for understanding how other organisms might react to the sounds.
Plants emit ultrasonic sounds in rapid bursts when stressed, which nearby creatures may respond to, according to scientists. The sounds are too high-pitched for the human ear, but insects and small mammals can detect them, raising the prospect that the noises might influence their behaviour. The sounds might be useful for nearby creatures, perhaps affecting which plants animals feed on or where insects lay their eggs. The discovery could make irrigation more efficient by using microphones alongside other sensors to detect when plants are short on water.
