1 . Animals can adapt quickly to survive unfavorable environmental conditions. Evidence is mounting to show that plants can, too. A paper published in the journal Trends in Plant Science details how plants are rapidly adapting to the effects of climate change, and how they are passing down these adaptations to their offspring(后代).
Plants are facing more environmental stresses than ever. For example, climate change is making winters shorter in many locations, and plants are responding. “Many plants require a minimum period of cold in order to set up their environmental clock to define their flowering time,” says Martinelli, a plant geneticist at the University of Florence. “As cold seasons shorten, plants have adapted to require shorter periods of cold to delay flowering. These mechanisms allow plants to avoid flowering in periods when they have fewer opportunities to reproduce.”
Because plants don’t have neural(神经的) networks, their memory is based entirely on cellular(细胞的),molecular(分子的),and biochemical networks. These networks make up what the researchers call somatic memory(体细胞记忆). “It allows plants to recognize the occurrence of a previous environmental condition and to react accordingly,” says Martinelli.
These somatic memories can then be passed to the plants’ offspring via epigenetics(表现遗传). “Several examples demonstrate the existence of molecular mechanisms modulating plant memory to environmental stresses and affecting the adaptation of offspring to these stresses,” says Martinelli.
Going forward, Martinelli hopes to understand even more about the genes that are being passed down. “We are particularly interested in decoding the epigenetic alphabet without changes in DNA sequence(序列),”he says. “This is especially important when we consider the rapid climate change, we observe today that every living organism, including plants, needs to quickly adapt to survive.”

2 . As you read this, pause to reflect on your recent interactions. As a politician, husband, and father, I encounter various spoken language styles: analytical or chatty, formal or informal, pointed or gentle, cooperative or decisive. Talk is the currency of politics. It is our way of negotiating, debating, and persuading. Talk is also the currency of learning-how we develop our ideas, deepen our thinking and share our feelings.
That’s why I want speaking skills, sometimes called “oracy”, to play an important part in Labor’s plans for a reformed school curriculum (课程).
Employers value speaking skills equally with reading and writing. The ability to speak well and express yourself should be something every child should master. But the curriculum doesn’t allow us to provide this. This is short-sighted. An inability to express your thoughts fluently is a key barrier to getting on and doing well in life.
Oracy is in part about good public speaking and debating skills, but in reality, it’s about teaching young people to make strong arguments, choose wise words, understand their audience, form meaningful social connections, and use facial expressions and body language to convey their message. Above all else it’s about finding your voice. To work out who you are and what you believe. If reading opens up a world of imagination and possibility, then speaking and listening opens up a lifetime of empowerment-a chance for those who feel invisible in their own country to be heard. It is about the confidence to speak out, to call out injustice or harm.
And the other side of speaking is listening, which can also be taught. Listening, truly listening, develops tolerance and understanding. And as parents we can play our part. We’ve all been there, at mealtimes, silent as we all stare at our devices. Our job, all of ours, is to get off our screens and give young people, and adults, the gift of listening.
So, oracy―speaking and listening―needs to be placed firmly at the heart of school life.

3 . The sperm whale is an astonishing creature. It’s longer than a semi-truck, weighs more than 90, 000 pounds and is the largest member of the toothed whale family. It’s known to dive 6, 500 feet in search of food, and to stay down there for longer than an hour at a time.
Perhaps most fantastically, the sperm whale’s brain weighs as much as 20 pounds-the biggest of any species on Earth. But when it comes to brains, is size all that matters? There’s a lot we don’t know about the sperm whale’s intelligence because it’s difficult to carry out neurological (神经的) testing on such a huge marine mammal. But some clues point to sperm whales being much smarter than we give them credit for.
A 2021 study published in Biology Letters, for example, looked back to 19th-century historical logbooks from whalers. Researchers found that sperm whales were at first easy to catch-but almost immediately, the whales learned how to evade hunters and whaling success dropped by 60 percent. The study suggests that the whales passed information to one another through soundwaves to avoid being caught.
Animals that have big brains usually have a few things in common. They usually live long lives; for example, sperm whales can live for 70 years or longer. Additionally, they’re capable of complex behaviors and they tend to be more socia1. Whales may work together to hunt or communicate in a language all their own.
What’s more, humans, whales and dolphins all have spindle neurons in their brains. These nerve cells make us capable of deeper thought, such as reasoning skills, memory, communication and adaptive thinking. And like humans, whales have emotional intelligence- meaning they＇re capable of empathy, grief and sadness. Still, in proportion to (与…成比例)our body size, the human brain is bigger than that of the sperm whale.
Yet there’s still so much we don’t know about how smart sperm whales really are. And just like the whalers of a century ago, we have likely been underestimating marine mammals, whether large or small, for as long as we’ve known of their existence.

5 . Most of us would like to be more creative, but we assume there is little we can do about it. Psychology professor K. Anders Ericsson claims that with enough practice, any of us can become experts. However, he is quick to add that this requires a specific kind of practice that Ericsson calls ‘deliberate practice’: that is, pushing beyond one’s comfort zone and setting goals that are above one’s current level of performance. He says he has yet to find the limits on being successful and he doesn’t believe them to be real.
Ericsson has looked primarily at artistic and athletic skills, but can these findings apply to creativity? Most experts agree that even if most people cannot hope to become creative geniuses, they can learn to become more creative through practice. Psychologists claim that there are actually two levels of creativity, which they refer to as’Big C’ and ‘small c’. Big C creativity applies to breakthrough ideas, ones that may change the course of a field or even history. Small c creativity refers to everyday creative problem solving, like creating a new recipe or improving a process, which psychologists subdivide further into similar and different thinking. Similar thinking involves examining all the facts and arriving at a single solution. In contrast, different thinking involves coming up with many possible solutions. What most people think of as creativity generally involves different thinking and can be taught, practised and learnt.
Even with practice, different thinking alone cannot make one creative, however. Scott Barry Kaufman, a cognitive psychologist, says that most creative people share one personality quality: openness to new experience. Since this quality and these processes have been identified, less creative people can try to emulate them. Normally, we tend to reproduce what we already know because creative ideas move us into unfamiliar territory involving risks and following the usual behaviors is comfortable.
Moving outside of our comfort zone, engaging indeliberate practice and tolerating contradictory ideas, risk and failure are all things we can learn to do better. It is unlikely that doing so will transform any of us into creative geniuses, but it does have the potential to increase our level of creativity.

7 . Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.
Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.
It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.
“Jazz seems like it’s not really a part of the American appetite,” Moran tells National Public Radio’s reporter Neal Conan. “What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It’s actually color, and it’s actually digital.”
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.
Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it’s the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”

8 . The student arrived early, sat front and center, and stood out in my classroom in more ways than one. I’d say that he was about 40 years older than his classmates in my undergraduate communications class. He eagerly jumped into class discussions, with his humor and wisdom of experience. And he was always respectful of the other students’ perspectives, as if each of them were a teacher. Jerry Valencia walked in with a smile—and he left with one too.
“These students gave me the confidence that I didn’t need to feel bad about my age,” Valencia says.
One day, I spotted Valencia on campus. He said he would have to stop taking classes that semester and reapply for next year. By then, he hoped to have earned enough money and have his student-loan papers in order. He asked seriously whether he could still sit in on my communications class.
Sure, I said. But he wouldn’t get any credit.
No problem, he said.
Soon there he was again, back at his old desk, jumping into our discussions on how to find and tell stories in Los Angeles—a 63-year-old man with as much energy and curiosity as any of the youngsters in class.
A lot of Valencia’s classmates apparently knew he couldn’t afford that semester’s tuition but was still doing the homework. “Here he is, willingly taking a class for the delight of it and benefit of learning,”says Jessica Espinosa, a 25-year-old junior. Afterward, I overheard Valencia wanted to stay in school until he earned a master’s degree, but it had taken him 12 years to finish community college, so he had a long way to go.
There is something splendidly unreasonable about Valencia’s determination to get a four-year degree and then a master’s. At his current pace, he’ll be 90 when he finally hangs all that paper on the wall. But that doesn’t seem especially relevant. He’s found all the youthful energy and academic opportunity stimulating. Valencia’s grade in my class this semester will not show up on his transcripts(成绩单). But I’m giving him an A—and in the most important ways, it counts.

In my first attempt to get control over my technology use, I set my phone to vibrate rather than ring. Soon after, another problem appeared. The act of continually checking the phone became a habit. I knew then that using only tips to permanently reform digital life is difficult. We should go past the notification settings (通知模式) on our devices or apps and consider the more essential topic of why we use so many apps in the first place. What all of us who are struggling with these challenges need is a technology usage philosophy, something that explains from the ground up which digital tools we allow into our lives, why, and under what conditions.
Cal Newport, a professor of computer science, defines Digital Minimalism (极简主义) as a “philosophy of technology use in which you focus your online time on a small number of carefully selected activities that strongly support the things you value, and then happily miss out on everything else.”
To do so, however, we cannot passively allow the tools and apps provided by the internet age to control how we spend our time or how we feel. Instead, we must take steps to draw the positive aspects of these technologies while sidestepping the negative aspects.

10 . Would you take a trip if you couldn’t use your cellphone? A new tour company called Off the Grid is asking travellers to put their cellphones away and not even use them for photos. The company founder, Zach Beattie, is developing his business, using money he saved from a tech job at a mapping company. He’s hired guides for every trip but will help lead the first few himself.
The first trip is to Lisbon, Portugal, in July. It takes 7 to 10 days, with small groups of up to 16 people. Prices range from $1,500 to $1,650, including accommodations, meals and ground transportation. The plan includes at least three excursions (远足) and two social events, with an emphasis on unique experiences over bucket-list sightseeing. The tour also includes surfing lessons, yoga on the beach, a day of sailing and dinner with a local family.
“When you’re somewhere new, there’s a lot to see and a lot of cool and interesting people to meet,” Beattie said. “Your phone can distract (使分心) you.” The phone ban won’t be enforced quite as strictly as it seems at first glance. “We want it to be voluntary,” he said. “We’re not collecting phones and throwing them in a locked trunk. It’s held by you, but put in your pocket, and you state your intentions for the week, whether that’s checking your social media once or twice a day or a total blackout.”
Tour-goers also get a “dumbphone” without Internet access that’s loaded with numbers for group leaders and other participants, both for emergencies and to promote socializing. Participants may bring regular cameras, but Beattie is hiring a photographer for each tour so there will be plenty of photos to remember the trip. Once the trip is over, participants will have access to those photos for use in social media posts.
