On a Tuesday afternoon in America's tech wonderland,Michael Feno,owner of Lucca Ravioli, stood outside his dear pasta restaurant,posing for pictures,his customers in tears.After 94 years, Lucca's doors shut on the last day of April 2019.A few blocks away,Borderlands Cafe closed the same day after 10 years in business.Owner Alan Beatts could not keep workers,even with a$15 minimum hourly wage.Who could live on$15 an hour in this city?
Tech is not what everyone talks about in San Francisco.It is money.Its estate(房地产）is the nation's costliest.A single-family home lists for$1.6 million,while$3,700 in monthly rent will get you a one-bedroom apartment.
For decades,this attractive city of hills,bordered by water on three sides,was a precious harbor for immigrants and artists.That's no longer the case.In a time of rare consensus(共识）， everyone agrees that something has become bad in San Francisco.
The city is rich in what other areas desire:start-ups,high-paying jobs,educated young people and rising property values.In the shadow of such wealth,however,San Francisco struggles with a homeless problem,which even forced Mayor London Breed to send a team to clean up human waste on the streets.
To many citizens,San Francisco has become unrecognizable in 10 years,as if it had received cosmetic surgery(整容手术）。It has less of what makes a city energetic.It has the lowest percentage of children of any major American city,and is home to about as many dogs as humans under the age of 18.To take a midday tour downtown is to be surrounded by an army of young workers,mostly white and male.Seeing a child who is learning to walk is similar to finding an endangered animal.
The city has also become less of a home to artists and musicians,because they cannot afford their practising spaces.How will the city create its next Grateful Dead or generation of Beat Writers? ＂Part of being an artist is being an observer of what's going on,says Victor Krummenacher,a member of a rock band who left the city in 2019 after 30 years."In this area,you're only stuck in the jam and costs.”
Everyone has a story about what is not here anymore:the inability to find a hardware store,a shoe repair or an independent music club.Businesses that were part of the memory,tradition and the lives of San Franciscans are being replaced with hipster(潮人）shops,which work to keep an artificial memory of its past.

We've known for years that plants can see,hear,smell and communicate with chemicals.Now, reported New Scientist,they have been recorded making sounds when stressed.
In a yet-to-be-published study, Itzhak Khait and his team at Tel Aviv University, in Israel, found that tomato and tobacco plants can make ultrasonic(超声的)noises. The plants "cry out" due to lack of water,or when they are cut. It's just too high-pitched(音调高的）for humans to hear.
Microphones placed 10 centimeters away from the plants picked up sounds in the ultrasonic range of 20 to 100 kilohertz(干赫兹)。Human hearing usually ranges from 20 hertz to 20 kilohertz."These findings can change the way we think about the plant kingdom,”they wrote.
On average,"thirsty"tomato plants made 35 sounds an hour,while tobacco plants made 11. When they were cut,tomato plants made an average of 25 sounds in the following hour,and tobacco plants 15.Unstressed plants produced less than one sound per hour,on average.
Perhaps most interestingly,different types of stress led to different sounds.The researchers trained a machine-learning model to separate the plants' sounds from those of the wind,rain and other noises of the greenhouse.In most cases,it correctly recognized whether the stress was caused by dryness or a cut.Water-hungry tobacco appears to make louder sounds than cut tobacco,for example.Although Khait and his colleagues only looked at tomato and tobacco plants,they think other plants also make sounds when stressed.
If farmers could hear these sounds,said the team,they could give water to the plants that need it most.As climate change causes more droughts,they said this would be important information for farmers. "The sounds that drought-stressed plants make could be used in precision(精准) agriculture, "said Anne Visscher at the Royal Botanic Gardens,Kew,in the UK.
Khait's report also suggests that insects can hear the sounds up to 5 meters away and respond. For example,a moth(蛾子）may decide not to lay eggs on a water-stressed plant.Edward Farmer. at the University of Lausanne,Switzerland,is doubtful.He said that the idea of moths listening to plants is"a little too speculative”。
If plants are screaming(尖叫）for fear of their survival,maybe we should be glad we can't hear them.
