1 . In nature, octopuses (章鱼) hunt mainly with their sense of touch, using their eight arms to feel out their environment for hidden creatures. Researchers at the University of Minnesota recently studied a different way octopuses hunt—when they identify prey (猎物) based on sight. The study findings show that the marine creatures are quite consistent and methodical in how they approach prey.
Lead researcher Trevor Wardill and his team placed California two-spot octopuses into water tanks, hiding them in caves where they would have one eye looking out. They then placed either fiddler crabs or white shrimp in the tanks to see how the octopuses would try to catch them, capturing the interactions on video. The crabs and shrimp behave differently when trying to escape from predators (捕猎者), so using both species gave the researchers an opportunity to see whether this led the octopuses to use a different arm for hunting depending on the prey.
Wardill’s team found that the octopuses almost always used the same arm to grab their prey. Specifically, the second arm from the middle of the octopuses’ body, on the same side of their body as the eye, caught the prey. If they needed more arms to grab prey, they would use the ones next to the second arm.
The octopuses also attacked differently depending on the prey. When faced with crabs, an octopus would move suddenly on top of the crab with its whole body. However, when catching shrimp, the octopuses would take one arm and reach out very slowly toward the shrimp, then grab it and latch (缠住) onto it with its other arms to pull it in.
Wardill and his team hope to do more research. They want to study the octopus’s brain as it attacks pre y to develop a better understanding of what role the creature’s nervous system plays in selecting the arms it uses.

2 . A comment from Zadie Smith caught my attention this week. Asked whether she had ever considered recording an album, the novelist responded, “I have a dream of having a Café Carlyle residency in New York in my 80s.” Here she is at the height of her success dreaming of a career Plan B just like the rest of us!
Weird Plan Bs fascinate me because for years I had one of my own. Despite being perfectly happy in my chosen profession, I had long harboured the fantasy of becoming a photographer and I took a lockdown leap and applied to art school to acquire some actual skills.
Has it brought me fame and riches? Not as yet. Like many people who dream of having a go at something different, I was focusing on creative fulfilment rather than my future finances. By the time I graduated in 2022, my dream of running a portrait photography business was looking a lot less practicable—in part thanks to AI head-shot generators.
If only I had had a little more Fobo, also known as the fear of becoming out-of-date. This workplace trend is an updated version of Fomo—the fear of missing out, which now feels like a poignant (辛酸的) throwback to more optimistic times. 22% of workers are worried that technology will put them out of a job. And who can blame them?
There is another reason that nurturing an alterative career might be risky. Research indicates that having a back-up plan can work against you. Having a Plan B as a safety net can cause people to make less effort at their day job and — unhelpfully — run a greater risk of losing it.
So, do I regret pursuing my Plan B? Not at all — hopefully I’ve got a few years before robot photographers take over the world, and I currently spend a day a week on photography. My only sorrow is something unexpected. For so many years. I had the fantasy of trying something new. My “someday” ambition sustained me through dull and boring days. But now I’m actually spending some of my week doing it, which has caused empty space in my life. It made me realize that having an alternative career to dream about is in itself sustaining and comforting. You might never do it, and that might not even matter. So, if you’ll excuse me, I need to go and start working on my Plan C...

4 . It was something rather irregular at an otherwise regular board of appeals meeting in Maine. A resident wanted a permission for not observing the no-chicken rule. But this wasn’t just any resident. It was C-Jay Martin, 25, who is blind and has epilepsy (癫痫) and autism. Chickens are what brought C-Jay joy despite his challenges. “Having something to share with other people was important to him,” said his mother, Amy Martin.
But Bangor is not OK with chickens. In fact, city rules clearly prohibit residents from keeping “fowl, goats, sheep, cattle or swine of any kind” and the municipal government urges the residents to obey the rules strictly. So, would the staid New England city of 31,000 make an exception for C-Jay and his emotional support hens?
It was with high hopes that Martin headed to the otherwise ordinary municipal meeting earlier this month. She told the appeals board she got the chickens in April after researching the Fair Housing Act, which prohibits discrimination in housing by landlords or municipalities, and finding it might allow her son an accommodation.
She was joined by neighbors and community members who showed up to support C-Jay and his chickens. One noted C-Jay regularly assumes the responsibility of feeding the chickens, despite his disabilities. Another said their cooing and soft noises are clearly a comfort to C-Jay. Others said Martin and C-Jay keep the chickens’ area in their yard very clean.
But there were some complaints. Some raised concerns about whether the presence of the chickens could attract rodents (齿类动物), and didn’t want an exception for C-Jay to open the door for others to keep banned animals.
City officials, seeming to side with C-Jay and his flock, assured attendees that no increased rodent activity would not be tolerated and any livestock permission would only apply to C-Jay Martin at his house.
In the end, it reached a consensus: the appeals board ruled that C-Jay had a need for the chickens. He would be allowed to keep them, although limits on the number were set, and noisy roosters prohibited.
Martin said her son is relieved and that his beloved chickens will stay. “When he’s sitting outside listening to an audiobook, or just hanging out in the backyard with the sun shining, he always knows where they are because he can hear them,” she said. “He’s never really alone.”

5 . Researchers have claimed a major step forward in the field of organ transplantation after a monkey survived for more than two years with a genetically engineered pig kidney.
Scientists have spent decades working out whether animal organs could ever work properly and safely in humans without them being rejected by the patient’s immune system, but the challenges have proved immense.
For the latest trial, researchers used a gene-editing tool called Crispr to alter genes in Yucatan miniature pigs before transplanting their kidneys into macaques (猕猴). The modifications altered genes to prevent organ rejection and remove pig viruses that could potentially be activated in recipients.
Writing in the journal Nature, the scientists describe how 21 monkeys got on after their kidneys were removed and a single genetically modified pig kidney was implanted. Monkeys typically survived no more than 24 days when the kidneys were edited to disable three genes that triggered immune rejection. But when the scientists added seven human genes that reduce blood clotting (结块), inflammation and other immune reactions, the monkeys survived seven times longer, typically for 176 days. When combined with treatment to restrain the immune system, the researchers report that one monkey survived for more than two years — 758 days — with the transplanted organ.
Curtis, the chief executive of eGenesis, said the long-term survival of at least some of the monkeys had put eGenesis on course to satisfy the US Food and Drug Administration requirement to see at least 12 months’ survival in animals before the team can launch a clinical trial in humans. “We are well on our way there,” Curtis said. “There simply aren’t enough kidneys to go around. In our opinion it’s the only near-term practicable solution.”
The team uses Yucatan miniature pigs as donors because at maturity their kidneys are roughly the same size of those in the adult human. In the monkey trial, the kidneys were transplanted at two to three months when the organs were much smaller.
Prof Tatsuo Kawai, an author on the study at Harvard Medical School, said the scientists expected the modified pig organs to perform better in humans than monkeys because “they are a better match”.

Every morning before going to school, Galen would stand in front of their bookshelf in the living room, focusing his sights on one book titled “The Greatest Explorer That Never Was”. It was kept on the top shelf. His mom would always read it to him when he was feeling sad. And lately, he’d always been feeling sad. His mom died.
He would try to think of a way to get the book. He’d thought about asking his dad for help but his dad had been spending more time in his office. Galen was on his own for this one and he saw it as a challenge he needed to overcome. This was his test.
At school, he would draw up plans on how he would do it. First, he planned on using the ladder they kept in the shed (小屋). So when he got home, he threw his bag on the couch and carried out the plan. But when he had his hands on and tried to carry it, immediately he realized that the plan was a failure-the ladder was too heavy for him to carry to the living room. He left the shed, defeated. He took out the notebook that he’d written his plans on. He crossed out using a ladder. He went to bed that night determined to come up with a new plan that would work.
His next plan was to use his mom’s old trampoline (蹦床). Using it would allow him to jump high enough, reach the top of the shelf, grab the book, and land on the ground. He did this about four or five times before deciding that this plan, like the one before, wouldn’t work.
Galen started coming with other plans as the days went on. After the unsuccessful mop and broom plan, he stayed up late that night hatching a new plan, which had a higher success rate than the others. It was to climb to the top of the shelf until he could just take the book. He’d just have to hold on to the sides a little tighter so that he wouldn’t fall off.

8 . Benefits of sharing jokes as a family
A well-chosen joke can have a big impact when speaking to a crowd or attempting to redirect a tense meeting.
Jokes improve language skills.
Jokes encourage reading and learning. Many parents and teachers report that joke books help motivate their reluctant or struggling readers to read more. Since jokes, by design, are for sharing, reading them aloud is particularly good practice for kids who struggle with reading fluently.
A.Jokes help kids build social relationships. |
B.Jokes aren’t just for the public stage, though. |
C.Humor can even help a person deal with mood disorders. |
D.Studies show humor can make information more memorable, too. |
E.Jokes are quick lessons about sounds in words and word meanings. |
F.Humor encourages family connection and can help ease kids’ anxiety. |
G.Also, it’s been a good chance to explain jokes he didn’t quite understand. |
9 . Adaptations are currently popular in the movie industry. We’re all familiar with film adaptations of books.
The most well-known version of a film being adapted to books is via the novelisation (小说化). Movie novelisations went through a boom period before the internet era. Fans wanted to know more about the fictional worlds and experience the story again in a new way.
Meanwhile, the screen to page process has also opened up the possibility of sequels (续篇). Perhaps there simply wasn’t financial investment to create a follow-up to a film. Maybe a sequel idea simply felt more appropriate for a novel.
But what are the benefits of reading a novel instead of waiting for the big screen version? Well, a novel can take its reader deeper into the mind of the characters that the film had to represent in a more visual way.
Book adaptations of films obviously won’t ever replace cinema, and there’s no need to choose one or the other.
A.But what about book adaptations of films? |
B.Besides, descriptions can be more detailed too. |
C.For a time, they were everything for cinema lovers. |
D.Films being adapted to books has been talked repeatedly. |
E.But they couldn’t simply google it, or immediately purchase the production on tape. |
F.Regardless, some terrific films have been expanded upon thanks to this medium. |
G.Actually, these two mediums are considerably interdependent and complementary. |
