1 . In much of the western United States, drought and access to fresh water is a critical issue. However, recently California came up with a novel solution. The state approved regulations that allow agencies to purify wastewater for drinking. This recycled wastewater may be consumed in homes, schools, and businesses.
As the population in California has exploded in recent decades, the state has struggled to meet demands for fresh water. Recycled wastewater will allow the state to increase access to the precious resource.
Recycled wastewater is not new to the state. It has previously been used in ice hockey rinks (冰球场), for crops, and to generate artificial snow. But now, water agencies will have the option to put recycled wastewater back into pipes for drinking. California is only the second state to allow purified wastewater to be consumed. The first was Colorado in 2022.
While the idea of drinking recycled wastewater may be off-putting, regulators spent more than a decade developing rules and regulations to ensure safety. Independent panels of scientists also reviewed the state’s rules around recycled wastewater consumption. All water will be treated for pathogens (病原体) and viruses before being available for consumption.
So far, the state’s plan has been met with approval from large water agencies. Many of them have plans to construct wastewater recycling plans over the next few years. In Southern California, the Metropolitan Water District of Southern California has set a goal aiming to produce 150 million gallons of direct and indirect recycled water per day. This water will be in the pipes of the 19 million people throughout the six counties that the agency serves.
Officials are aware that a certain amount of public convincing may still be necessary. However, they remain optimistic about the future of the project, reminding consumers that the water is safe, and that recycled water is already in use in California.

3 . Airlines already place common-sense limits on young passengers. For example, on United Airlines, babies younger than seven days old can’t fly. And lately, there’s been a heated discussion about keeping little ones out of business class. Why draw a line there?
No one’s suggesting a ban on babies, or even kids, from flights. That wouldn’t make sense for passengers or airlines. Banning children from flights would be a financial disaster for airlines. That’s because leisure travel accounts for two-thirds of all air travel incomes, and people sometimes take their kids on vacation with them despite their kids’ screams, tantrums (发脾气) and meltdowns.
But maybe it’s time for a little course correction when it comes to children. Maybe there are places we should keep baby-free, such as a section of the plane, or the entire plane. It will benefit passengers because all or some of them will arrive at their destinations well-rested and ready for their vacation or work.
There are some passengers who believe airlines shouldn’t restrict young passengers from flying anywhere. They think people seem to forget that babies and toddlers are people. Restricting children may be an easy solution, but it will have long-term consequences. They’re not going to like the humans they grow up to be.
There’s an equally convincing argument that we should place sensible limits on babies. Some may have physiological challenges that make a flight unbearable. Others may not have the patience to sit in a pressurized aluminum tube for hours. Some of them are just not ready to sit still for a 12-hour flight. But the biggest challenge for babies and toddlers is the pressure changes on the climb to and fall from cruising (平稳行驶的) altitude.
Babies will keep flying anyway. So there are always a few ways of staying calm when you are seated close to a seat-kicking child who raises the noise level on your next flight, for example, asking a flight attendant for help, buying a good pair of noise-canceling headphones or earplugs or avoiding the babies entirely by booking the red-eye flights.

4 . “In the United States, 40 million Americans are food insecure. They don’t know where their next meal is going to come from,” said Aidan Reilly, who co-founded Farmlink. “Meanwhile, in the United States we’re throwing out over 100 billion pounds of food every year.”
Started during the hard period in spring 2020, Farmlink was initially supposed to help struggling families and food banks. Reilly and his childhood friend James Kanoff were reading and watching news about food shortages, and they learned that local farms were forced to destroy spare produce that they couldn’t sell, especially with restaurants, schools and hotels closed. Reilly, Kanoff and a group of friends worked together over Zoom, text and e-mail to contact farms. They didn’t really set out to start a nonprofit then but just thought it would be great to figure out one way to help starving (饥饿的) people.
With “we’ll come to you” as their catchphrase, the group rented trucks and attempted to do all the food pickup and deliveries themselves. They had a lot of difficulties in the beginning, but they made it work, moving more than one million pounds of produce from farms to food banks within just two months and transforming their project into a massive logistics operation in the process. Word spread, and more and more young people at home during the pandemic reached out to help.
Farmlink has worked with more than 100 farms and 300 communities in the United States, rescuing and moving enough food to distribute (配送) more than 64 million meals. “The bigger Farmlink gets, the bigger our worldview gets. There are everyday Americans who live next to us and don’t know how they’re going to feed their kids. And that’s exactly who we’re doing this for,” Reilly said.

5 . Have you ever wondered why most store-bought tomatoes are so tasteless? Does it relate to climate change or soils? The answer has something to do with farmers’ income: Tomato farmers care about output, and the genetic variants (基因变体) associated with output are not associated with tasty tomato flavor, a new study finds.
Is it possible to bring back the rich, sweet flavor of the tomato? To find out, Denise Tieman, research assistant at the University of Florida, explored which genes are associated with tomatoes’ taste.
In an attempt to fix supermarket tomatoes, Florida researchers looked at 398 different types and identified the chemical and genetic makeup of each one. They had participants taste-test 101 varieties, cross-referencing the participants’ favorites with their research findings. They ended up with 13 genetic compositions that are most likely responsible for giving tomatoes their flavor. The researchers then measured the content of the 13 flavor compositions in each of the tomatoes, and identified about250 genetic loci (遗传基因座) that controlled tomato flavor. And the researchers also wanted to explore why supermarket tomatoes have no taste.
It turns out that for industrial growers, it all comes down to priorities (优先性). North American consumers want year-round availability, so farmers started raising their plants for qualities like firmness, shelf life, high output and disease resistance, says Tieman. “Not to discount any of that because it’s all important. We want to have tomatoes in the grocery stores year round and be able to ship them long distances when it’s winter in the north. If they have to be shipped from Florida or Mexico, you need to have all those features.” But as growers planted tomatoes to meet those priorities, the flavor gradually disappeared.
Going back to the old varieties is not an option—at least, not for grocery stores. But the researchers believe that there is hope for a growable tomato that’s both long-lasting and flavorful in about three to five years.

6 . Traditionally, the number of meaningful social relationships one can maintain is around 150. This concept finds its roots in the natural development of the human brain. However, in the digital age, where our social connections extend far beyond the geographical boundaries (界限), we easily create more connections with the help of the rising online platforms. Then, a question arises: Does the digital age rewrite the rules of social connection?
A study published in Cyberpsychology, Behavior, and Social Networking explored the effect of social media usage on the size of social circles and the closeness of relationships. The researchers found that more time spent on social media made for a larger number of online “friends,” but not a larger number of offline friends. Further, the findings were not linked to feelings of closeness towards online or offline friends.
Another study from the European Journal of Information Systems studied the link between social media usage and “social overload” — the feeling that too much of the energy for socializing is being used up by online relationships. The authors found that social media usage directly contributed to the experience of social overload, related to digital tiredness and dissatisfaction with social media.
With social media platforms rising, one’s ability to connect with people challenges the traditional concept. The brain, used to manage a limited number of relationships, now fights against the difficulties of dealing with a large number of digital connections, leading to a less attention and feeling investment (投入) in a relationship. And the online shallow connections can not develop meaningful, lasting relationships that stand the test of digital distance.
Therefore, in the digital age’s social whirlwind, instead of drowning (淹没) in a sea of weak interaction (互动), choose to engage in meaningful conversations and focus on the handful of relationships that truly fit your heart. Hug the beauty of face-to-face connections, allowing the richness of human interaction to flower beyond the digital world. By doing so, we create digital and physical spaces that truly improve our well-being.

7 . If sales generally feel hard to resist, the sale in front of Arron Schurevich was the ultimate test: a new car just like the one he’d loved. And it was more than a 20% discount. “I figured that I would be a fool not to take advantage of that,” says Schurevich. After he drove the car off the lot, the deal turned sour. The brand-new car quickly needed repairs. Schurevich now jokes that he paid a tax for being a fool.
Why is it so hard for the human brain to resist a discount? Spotting something you’d like to buy activates your brain’s reward circuitry (奖赏回路). It gets especially heightened if it’s something you’ve been fascinated by — say, the same car you’ve enjoyed for years. Additionally, the discount itself often registers as a win, delivering its own kind of joy, says Jorge Barraza, a consumer psychologist at the University of Southern California.
“Not only are we getting the product,” Barraza says, “but we’re also getting that reward that we discovered something; we’ve earned this extra thing.”
Stores, of course, know all this and try to push our buttons. “Limited-quantity, limited-time, scarcity-marketing promotions—they get people’s blood pumping,” says Kelly Goldsmith, who studies this as a marketing professor at Vanderbilt University.
It’s really hard to always approach sales rationally. One buying strategy experts recommend is to make a shopping list in advance and then, stick to it. Another is to research items — beforehand or on the spot, checking online — to weigh whether the sale is really a good deal.
“The human brain has essentially evolved to feel first and think next, which is why you need to give yourself time to cool off from your instant reaction when in front of a sale,” says Goldsmith.

8 . People don’t usually become homeless suddenly. It’s a chutes-and-ladders (阶梯状) process. A large new statewide study takes a closer look at the period just before homelessness, by asking a representative sample of almost 3,200 homeless people from all over the state about the dilemma they fell into, and what would have helped.
Some of the findings were unsurprising: in the state with the nation’s largest homeless population, people are unhoused because they don’t have enough money, or have experienced trauma (创伤). A quarter of all survey participants had experienced family violence, and their lives and health get much worse once homelessness strikes. But some of the report’s data run counter to popular perception: for example, most homeless people are not from out of state, contrary to the common belief that homeless people move to California for the weather and policies.
The study’s lead author, Dr. Margot Kushel, says there’s a “doom loop” of homelessness, where people have jobs that don’t cover living expenses, so they lose their homes, and the resulting instability makes it harder to keep their jobs.
Kushel points to really exciting models of homelessness prevention, where in low-income communities, they’ll have subway and bus posters saying, “Are you at risk of becoming homeless? Call us.” These programs might offer anything from cash to finding landlords or roommates. “What was really striking to us was how little money people thought it would have taken,” says Kushel. Most participants suggested that less than $500 a month, or a onetime payment of $10,000, would have kept them housed. Kushel cautions that the vast majority of mental health issues among the study participants are anxiety and depression. It’s likely that the lack of resources results in those conditions, rather than the illness causing the homelessness. “The driving issue is clearly the deep poverty,” Kushel says.
