2 . Compared to robots, human bodies are flexible, capable of fine movements, and can change energy efficiently into movement. Drawing inspiration from human gait, researchers from Japan crafted a two-legged biohybrid robot by combining muscle tissues and artificial materials. This method allows the robot to walk and pivot.
“Research on biohybrid robots, which are a mix of biology and mechanics, is recently attracting attention as a new field of robotics featuring biological function,” says corresponding author Shoji Takeuchi of the University of Tokyo, Japan. “Using muscles as actuators allows us to build a compact robot and achieve efficient, silent movements with a soft touch.”
The research team’s two-legged robot, an innovative bipedal design, builds on the legacy of biohybrid robots that take advantage of muscles. Muscle tissues have driven biohybrid robots to crawl and swim straight forward and make turns—but not sharp ones. Yet, being able to pivot and make sharp turns is an essential feature for robots to avoid obstacles.
To build a nimbler robot with fine and delicate movements, the researchers designed a biohybrid robot that copies human gait and operates in water. By alternating the electric stimulation between the left and right leg every 5 seconds, the biohybrid robot successfully “walked” at the speed of 5.4m m/min(0.002 mph). To turn, researchers repeatedly zapped the right leg every 5 seconds while the left leg served as an anchor.
The robot made a 90-degree left turn in 62 seconds. The findings showed that the muscle-driven bipedal robot can walk, stop, and make fine-tuned turning motions.
“Currently, we are manually moving a pair of electrodes to apply an electric field individually to the legs, which takes time,” says Takeuchi. “In the future, by integrating the electrodes into the robot, we expect to increase the speed more efficiently.
The team also plans to give joints and thicker muscle tissues to the bipedal robot to enable more complicated and powerful movements.

3 . Some children love reading, some dislike it, and many are in between. Most children and adults are drawn to reading materials that are engaging and understandable.
Compare books to films.
Encourage curiosity about vocabulary. As your child reads books, suggest that you look up difficult or unfamiliar words in the dictionary together.
Strengthen spelling skills. If you are making flashcards with difficult words, have your child practice spelling the words out loud or on paper. Give your child the opportunity to double-check spelling and find mistakes independently. This is a great strategy to use throughout the year.
A.Create literature with your child. |
B.Ask your child to make up stories. |
C.Compare how they are similar and how they are different. |
D.Have your child read a book and then check out the video version of the book. |
E.But, your child will eventually have to read uninteresting or complicated materials. |
F.It teaches your child to self-correct and also reduces their fear of dealing with difficult words. |
G.Consider making flashcards of these words and guessing the meanings before finding the definition. |
4 . The morning commute(通勤)is never fun, but if you pass through Stevenage on your way to work, your morning might be a little brighter thanks to Nala the cat.
Dragging yourself out of bed in the morning and off to work is hard, especially on dark winter mornings. You might be a little more inclined to head out of the house with a spring in your step if your commute started at Stevenage Station, where you’d be greeted by a ginger cat called Nala.
Usually found sitting on a ticket gate, four-year-old Nala lives close to the station with her owner Natasha Ambler, and often heads to station at rush hour to enjoy attention from commuters. Ambler created a social media page called The Adventures of Nala where hundreds of people have shared photos of the adventurous cat.
Recent photos include Nala waiting in line for her “cat-purr-ccino” at Costa, snoozing(打盹)on newspaper stands and posing with commuters at the station barriers.
Nala wears a GPS tracking device so that her travels can be traced, and is usually found at the railway station or the next door leisure park. As well as the usual collar with her name and owner’s contact information, Nala wears a tag to let people know that she’s not lost.
Ambler reported that she’s not worried about Nala in the slightest: She’s obviously well-loved and she’s very happy doing what she does—I just hope one day she doesn’t actually try to get on a train.
Nala brings a ray of joy to Stevenage commuters with her playful antics. Her presence not only brightens mornings but also fosters a sense of community, as evidenced by the shared photos and interactions on social media. Her owner’s care and Nala’s adventurous spirit ensure that she’s a beloved and safe addition to the station environment.

5 . Great whites, the largest predatory(捕食性的)sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Wildlife filmmaker Carlos Gauna and UC Riverside biology doctoral student Phillip Sternes were scanning the waters for sharks on July 9, 2023, near Santa Barbara on California’s central coast. That day, something exciting appeared on the viewfinder of Gauna’s drone camera. It was a shark pup(幼崽)unlike any they’d ever seen.
“We enlarged the images, put them in slow motion, and realized the white layer was being shed(脱落)from the body as it was swimming,” Sternes said. “I believe it was a newborn white shark shedding its embryonic layer.”
These observations are documented in a new paper in the Environmental Biology of Fishes journal. What Gauna and Sternes observed could help solve the longstanding mystery of great white birthing habits. This may well be the first evidence we have of a pup in the wild. Great whites, referred to only as white sharks by scientists, are gray on the top and white on the bottom. But this roughly 5-foot-long shark was pure white.
Though the paper authors acknowledge it is possible that the white layer the shark shed could have been a skin condition, the two believe what they saw was in fact a newborn great white. First, great white females give birth to live pups. A second reason is the presence of large, likely pregnant great whites in this location. Finally, this location off the coast of central California has long been proposed as a birthing location for great whites. Many scholars believe great whites are born farther out at sea.
Great whites are listed as an international endangered species. “Further research is needed to confirm these waters are indeed a great white breeding ground. But if it does, we would want lawmakers to step in and protect these waters to help white sharks keep thriving,” Sternes said.

The day I started working out with my personal trainer, Teresa, I told her that overall, I wanted to get in shape and get stronger. More specifically, I wanted to lose 10 pounds by swimsuit season.
“Good, you have both long-term and short-term goals,” Teresa said. “That will help keep you motivated.” Then she warned, “I’m going to push you pretty hard, Sue. And you’re going to have to push yourself, too.”
She had. And so had I. Yet here I was at the gym, months later, the same old Sue with the same weight. I looked in the mirror and said, “I’m still so fat. It’s too hard for me to lose 10 pounds.” 1 wasn’t feeling very motivated. “Let’s start with something different today,” Teresa said.
I thought she was going to show me a new exercise. Instead, she took something small and green out of her pocket. A rubber band(橡皮筋). Teresa took my right arm and placed the band onto my wrist, a determined look on her face. “This will solve your problem,” she assured me. I didn’t mean to be rude, but I had to ask, “How is this rubber band going to help me get in shape?”
“Your weight is not your biggest problem,” Teresa said. “What’s really holding you back is that you’re always putting yourself down.” I knew that better.1 had grown up constantly comparing myself to others, and I fell short every time.
Teresa said she was tired of hearing all the negative words I directed at myself. “Your negative thinking is a bad habit, and it’s time to break it,” she declared. The plan was simple. Every time I thought or said something that put myself down, I was supposed to pull the rubber band—hard—and break free from that negative mindset.
I agreed to try the rubber band. Then I left the gym and drove home. A pile of mail was waiting. I looked through it. There was an official-looking letter from my bank, 1 tore open the envelope. It was an overdraft(透支的) notice. One of my checks had bounced because I’d been late putting money into the account. My cheeks burned when I saw it was the birthday check I had sent to my niece. I really messed up now! How could I be so stupid?
