Stressed plants emit noises that can be heard by nearby insects up to one metre away, scientists have found.
Tomato and tobacco plants suffering from dehydration or severed stems make the sounds — similar to bubble wrap popping — comparable in volume to normal human conversation, researchers in Israel report.
The frequency is too high for human ears to detect but they can likely be heard by insects, mammals and possibly other plants, according to the study published in the journal Cell on Thursday.
“Even in a quiet field, there are actually sounds that we don't hear and those sounds carry information,” said evolutionary biologist and senior author Prof Lilach Hadany, from Tel Aviv University.
“There are animals that can hear these sounds, so there is the possibility that a lot of acoustic interaction is occurring.”
Ultrasonic vibrations have been recorded from plants before, but the Israeli study provides the first evidence that it is airborne.
“Plants interact with insects and other animals all the time and many of these organisms use sound for communication so it would be very suboptimal for plants to not use sound at all,” Prof Hadany said.
Sound recordings of plants could be used in agricultural irrigation systems to monitor crop hydration and help distribute water more efficiently, the researchers say.
“The fact that plants are making these sounds opens a whole new avenue of opportunities for communication, eavesdropping and exploitation of these sounds,” said co-senior author and neuro-ecologist Yossi Yovel.
“Now that we know that plants do emit sounds, the next question is — who might be listening?
“We are currently investigating the responses of other organisms, both animals and plants, to these sounds, and we’re also exploring our ability to identify and interpret the sounds in completely natural environments.”
Researchers used microphones to record healthy and stressed tomato and tobacco plants, first in a soundproofed acoustic chamber and then in a noisier greenhouse environment.
They stressed the plants by not watering them for several days and cutting their stems. The team found that the stressed plants emit far more sounds than healthy ones.
The plant sounds resemble pops or clicks, and a single stressed plant emits between 30 and 50 an hour at seemingly random intervals.
“When tomatoes are not stressed at all, they are very quiet,” said Prof Hadany.
Water-starved plants began emitting noises before they were visibly dehydrated, and the frequency of sounds peaked after five days without water before decreasing again as they dried up completely.
They focused on tomato and tobacco plants because of their ease to grow and standardise in the laboratory but other plants were also tested.
“We found that many plants — corn, wheat, grape and cactus plants, for example — emit sounds when they are stressed,” Prof Hadany said.
The exact mechanism behind these noises is unclear, but the researchers suggest that it might be due to the formation and bursting of air bubbles in the plant’s vascular system, a process called cavitation.

Key findings of Jenkins report
- Founder of the Muslim Brotherhood, Hassan al Banna, "accepted the political utility of violence"
- Views of key Muslim Brotherhood ideologue, Sayyid Qutb, have “consistently been understood” as permitting “the use of extreme violence in the pursuit of the perfect Islamic society” and “never been institutionally disowned” by the movement.
- Muslim Brotherhood at all levels has repeatedly defended Hamas attacks against Israel, including the use of suicide bombers and the killing of civilians.
- Laying out the report in the House of Commons, David Cameron told MPs: "The main findings of the review support the conclusion that membership of, association with, or influence by the Muslim Brotherhood should be considered as a possible indicator of extremism."

- A ban on launches and other activities with ballistic missiles capable of delivering nuclear weapons, as well as ballistic missile technology transfer and technical assistance
- A targeted global asset freeze and travel ban on Iranian individuals and entities
- Authorisation for countries to inspect Iran Air Cargo and Islamic Republic of Iran Shipping Lines cargoes for banned goods

Pharaoh's curse
British aristocrat Lord Carnarvon, who funded the expedition to find the Tutankhamun tomb, died in a Cairo hotel four months after the crypt was opened.
He had been in poor health for many years after a car crash, and a mosquito bite made worse by a shaving cut led to blood poisoning and pneumonia.
Reports at the time said Lord Carnarvon suffered from “pain as the inflammation affected the nasal passages and eyes”.
Decades later, scientists contended he had died of aspergillosis after inhaling spores of the fungus aspergillus in the tomb, which can lie dormant for months. The fact several others who entered were also found dead withiin a short time led to the myth of the curse.

Why are asylum seekers being housed in hotels?
The number of asylum applications in the UK has reached a new record high, driven by those illegally entering the country in small boats crossing the English Channel.
A total of 111,084 people applied for asylum in the UK in the year to June 2025, the highest number for any 12-month period since current records began in 2001.
Asylum seekers and their families can be housed in temporary accommodation while their claim is assessed.
The Home Office provides the accommodation, meaning asylum seekers cannot choose where they live.
When there is not enough housing, the Home Office can move people to hotels or large sites like former military bases.
