1 . Electrically powered vertical-take-off-and-landing (eVTOL) aircraft—flying cars are an idea whose time has not quite yet come, but is fast approaching. Many firms are offering various designs. None of these, however, will be Jetson-like family flying cars. Pivotal, based in Silicon Valley, by contrast has crafted something that people can purchase and pilot themselves. Helix is a single-seat vehicle, so “flying motorbike” might be more accurate. From next year, many people will be able to order one for personal use, though they will not be able to take delivery until June.
Marcus Leng founded Pivotal in 2011, and some back-of-the-envelope calculations he made suggested that electric lift-off of a human-carrying craft, using motors powered by the lithium-ion batteries ought to work. He thus built a model and flew it in the garden of his house in Warkworth, Ontario.
Now, after ameliorating it, the firm thinks it has something marketable. The aircraft has, nevertheless, changed little in its fundamentals over the years. It has two pairs of wings and eight propellers (螺旋桨), making it slightly resemble a squashed “H” when seen in the sky from below. And there is no undercarriage. Instead, its belly is curved in a way similar to a humpback whale’s, so it rocks to stability after landing.
Pilot’s licence or not, buyers will still need some training to fly a Helix. Pivotal insists on this. For the same reason, the craft’s software will stop the pilot doing anything that does not fit its safety rules. And if, despite this, something does go wrong, it is fitted with a parachute(降落伞).
The Helix’s top speed is a respectable 100 kph, but its range is only 30 km. And refueling it is a bit of a pain. Filling up from the mains takes four and a half hours, though a special high-power system similar to those employed for electric cars can bring that down to 75 minutes. While Helix still doesn’t compare to the flying car from the Jetsons, it could be a step forward.

Acts of kindness have the power to not only brighten our day but also restore our faith in humanity. While young children are often reminded to be kind, real-life examples of young people showing charity prove that kindness knows no age limit.
In the busy city of Detroit, 14-year-old twin sisters, Makhia and Makyla Vincent, were on their usual route to school when something caught their attention. On the snow-covered ground lay a wallet, seemingly out of place. “What do you think we should do?” Makyla whispered, her voice low.Makhia bit her lip, her eyes locked on the wallet. “I don’t know, but we can’t just leave it here. What if the owner needs it desperately?” Finally, worry and curiosity got the better of them, and they decided to take a look inside.
Slowly, Makhia reached out and picked it up. As she opened it, the sisters gasped at the same time. To their surprise, they discovered a large amount of cash, bank cards, and a military ID. It was clear that whoever owned this wallet held great value for these possessions. Instantly, the girls knew exactly what they had to do. Coming from a family with a veteran (退伍军人) grandfather, the sisters felt a deep sense of empathy for the person who had lost the wallet.
The girls looked closer to inspect the military ID. It belonged to a Marc Walsh, a middle- aged man who looked serious. “We have to find this Marc Walsh,” Makhia declared, her voice filled with determination. “But how?” Makyla asked. Makhia thought for a moment, “Maybe there’s an address on one of these cards. Let’s see if we can find any clues.”
They carefully examined the bank cards and discovered that one of them had an address on it. It was located not far from where they stood. With a sense of purpose, the twins decided to make their way to the address, wallet in hand.

3 . On July 28, I retired from my position. After teaching for many years, I looked forward to kayaking (划独木舟) with my grandsons, seeing friends and traveling for leisure with my husband. But my body had other plans for me. A broken spine (脊椎) in my back took me down a path that upended my plans.
I have long had back pain. However, I pushed through the pain to do my work, which worsened my condition. Doctors urged an operation when increased disability meant I could not sit, stand or walk for a long time. But I wanted to see whether physical therapy (治疗) could create an easier option.
Indeed, hard work with a great physical therapist has let me improve my mobility, sitting and standing. But X-rays told a different story. My spine was unstable and bending. After careful consideration and a second opinion from another professional, I agreed to surgery yet in the near term. Needless to say, the past months have been tough and the way ahead will be even tougher. Kayaking with my grandsons in the peacefulness of the lake is all out of reach, for now.
When I met my physical therapist for the first time, I was a mess. He listened to me outline my history with tears and then calmly said, “You have to make friends with your body.” I have repeated that line to myself daily and worked to embrace my body. I have focused on gratitude. I’m grateful that I do not have a fatal disease. I’m grateful that the body I have remains alert to the world, loved by family and friends. I’m grateful that I am still myself.
I don’t know exactly how the future will play out. The surgeon assures me that I should be able to get in my kayak by summer. But I may have to make friends with a different body, one that is mine regardless of the shape.

8 . Remember Malcolm Gladwell’s famous “10,000-hour rule” from his bestselling book Outliers? It proposes that achieving mastery in any field requires roughly 10,000 hours of practice, emphasizing the importance of early professionalization and intensive practice for becoming an elite in a particular field.
This approach, known as “deliberate practice”, encourages setting goals from a young age, investing time and specializing in a specific field. On paper, it sounds like a good path to success, but when we look at the lives of elite athletes, musicians and scholars, we find a different story. In reality, many individuals who have risen to the top of their respective fields took a more diverse and winding route. They often explored a wide range of activities, gained a broad skill set, and only specialized at a later stage in life. In other words, the idea that one must know one’s specialization from a young age is fundamentally wrong.
Studies have shown that an approach called the “sampling period” is often more effective for achieving success. During this phase, individuals try various activities, gain diverse skills, identify their strengths and weaknesses, and only choose a field to specialize in once they have a clearer understanding of their passions and abilities.
Elite athletes, for example, rarely specialize in a single sport at a very young age. Instead, they engage in a variety of sports during their formative years, which allows them to acquire broad physical skills and discover their interests and talents. These early diversification experiences provide valuable lessons that can be applied to their chosen sports.
Consider the journey of Roger Federer, one of the greatest tennis players of all time. At the age of 6, he dabbled in rugby, skiing and wrestling, only returning to tennis later. The trial period benefited him not just because he found his true passion but also because his experiences in various sports enriched his tennis game with a unique set of skills.

10 . Someday, you may no longer need to brush your teeth by hand. Instead, a group of billions of nanoparticles (纳米粒子) could automatically do all that work for you. It would be especially life-changing for people who find it difficult or impossible to hold and move a toothbrush.
Steager, an engineer at the University of Pennsylvania (Penn) in Philadelphia and Hyun Koo, an inventor and dental researcher there, found a way to form the nanoparticles into long, skinny bristles (刷毛), a lot like the ones on a toothbrush. But these bristles shape-shift to fit whatever surface they encounter.
The tooth-cleaning robot works thanks to two magnets (磁铁). One goes each side of the teeth. The nanoparticles sit in a liquid between the magnets. When the magnets are turned off, the nanoparticles move randomly in the liquid. As soon as one magnet gets turned on, the nanoparticles gather together near its center. When the researchers turn on the other magnet and turn off the first one, the nanoparticles extend outward in long, skinny bristles When there’s a tooth in the way, these bristles can’t stretch out as far as they want. So they push against the tooth’s surface. If there’s a gap between teeth, they push into the gap. Moving the magnets makes the bristles move against and between teeth. All that motion cleans the teeth. As a bonus, the nanoparticles also have strong power to kill viruses.
The new device is just a proof of concept The researchers still need to turn it into a product that people will want to use. “There’s a lot of engineering to get from here to there, but every good idea needs to have a start.” says Steager.
