1 . In recent studies we have been investigating mirror writing by typical 4- to 6-year-old children. The term is used because the characters — numbers and capital letters — are reversed (反向), yet are correct when looked at in a mirror.
Mirror writing entered the scientific literature in 1878. The explanations for the phenomenon were not only insufficient but also often wrong. One of them is — writing with the left hand. Throughout the 20th century, scientific journals have published mirror writing mostly produced by left-handed children. Even today, left-handedness is often the favorite explanation of teachers when children produce mirror writing.
The explanation we find for the phenomenon of mirror writing of characters works on two successive levels, the first cerebral and the second behavioral. The cerebral level shows that the brain removes orientation (left or right) when storing images, a process called symmetrisation or mirror generalization. This mirror-generalization process leads children aged 5 to know, from memory, the shape of the characters, but not their left/right orientation. Given the features of the process — horizontal mirror in the visual modality (视觉模式) — it is important to note that the initial learning of the form of the characters by the children is mainly visual, and that the children only produce horizontal mirror writing.
At the behavioral level, when children write the characters from memory, they must give them an orientation. In countries whose primary languages are written in Latin characters — written from left to right — children most often point them toward the right. This leads them to reverse mainly the left-oriented characters: J, Z, 1, 2, 3, 7, and 9. However, when spatial constraints cause them to write from right to left, the children instead reverse the right-oriented letters.
Since this explanation has nothing to do with the handedness of the children, it can be predicted that right-handed children will reverse characters almost often as left-handed children, and that – left-handed or right-handed – children will primarily reverse left-oriented characters in Western culture. This is because they strictly orient the characters in the direction of writing.

3 . Most people, if you quizzed them, probably wouldn’t know how much of all global trade is done by sea. It’s one of several reasons that the pollution and carbon emissions from shipping gain much less attention than those from road transport and other industries. It’s over the horizon, out of sight and out of mind.
Today, the international shipping industry is the main mode of transport for around 90 per cent of world trade. It’s powered almost entirely by fossil fuels. Studies show that alternative technologies and zero-emission fuels — including electrofuels such as hydrogen, ammonia and methanol — have the potential to significantly reduce the industry’s carbon footprint and thus require urgent implementation (实施). There’s just one catch: they don’t exist yet.
Even if the technology were available, the infrastructure (基础设施) for that technology or fuel is going to take time to develop. And an even bigger challenge is going to be whether that methanol or ammonia fuel is green, which touches on other industries such as renewable electricity. Do we even have enough renewable electricity in the world to be able to generate these fuels? It’s a complex supply chain that requires cooperation across the industry. It’s not something that one company can solve by itself.
According to Piotr Konopka, senior manager for energy and decarbonisation (碳减排) programs at DP World, there are some simple behavioral changes that can help cut down on fuel used in the meantime, from the regular maintenance and reduced idling of port equipment to the implementation of weather routing that helps ships avoid rougher, more fuel-intensive stretches of water. “Of course, efficiency is unlikely to ever reduce emissions by more than five or ten per cent, but it’s definitely a low-hanging fruit,” he says.
“This is the last moment for the IMO to act decisively to eliminate shipping emissions” says Delaine McCullough, shipping emissions policy manager at environmental NGO Ocean Conservancy. “We need countries to demand that the IMO set strong emission-reduction goals and take action at home if the IMO fails to do the right thing.”

4 . A common claim states that a sheet of paper cannot be folded in half more than seven times. But is this true?
In 2002, Britney Gallivan, then a junior in high school in Pomona, California, folded a single piece of paper in half 12 times. She currently holds the Guinness World Record for the most times to fold a sheet of paper in half.
The prompt that led Gallivan to accomplish this was an extra-credit challenge in math class to fold anything in half 12 times. Her teacher asked the students to fold something thicker: a piece of paper.
Gallivan said “it was very frustrating, as I had many unsuccessful attempts at trying to fold different papers in half. I began to question if folding paper in half more than eight times could be impossible.” However, Gallivan recalled. “I knew I needed to understand what was limiting the folding progression.”
The equations (方程式) that Gallivan came up with calculated how many times a sheet of paper could be folded. She found that in order to fold many times, a long thin sheet is needed — the more a sheet is folded, the thicker the resulting stack becomes, and once the stack becomes thicker than it is long, there is nothing left to fold. She ultimately set her record with a sheet of tissue paper she found online that was 4,000 feet (1,219 meters) — more than three-quarters of a mile, or over a kilometer long, Guinness World Records noted.
“Working on the problem took a tremendous amount of time and effort,” Gallivan said. “As frustrating as it was at times, I learned an immense amount from the experience, which has been valuable to me throughout my life in more capacities than one would expect.”
Since Gallivan set her record, others have made claims of folding a sheet of paper more than 12 times. Still, “I anticipate that my current record will be surpassed,” Gallivan said.

5 . Sometimes, determining which projects you should devote your time and energy to first takes energy you don’t have to spare (which is why we have tips for how to do it). But even when you know what tasks need to be done, you still need to figure out how to prioritize them. Try the 3-3-3 method.
This technique comes from Oliver Burkeman, author of Four Thousand Weeks: Time Management for Mortals($13.99). He advocates planning each workday around a 3-3-3 model, first devoting three hours to deep work on your most important project. Next, complete three other urgent tasks that don’t require three hours of focus. Finally, do three “maintenance” tasks, like cleaning, answering emails, or scheduling other work.
What distinguishes this method from other approaches are those first three hours of deep work. Jumping into them first means you’ll be fresh, focused, and more likely to be able to jump into a task without getting distracted. Keep those three hours free of emails, texts, chats, or other menial duties, to the best of your ability. (Check out our full guide to engaging in deep work here.)
Deep work produces major productivity, so you’ll get a lot accomplished if you commit to it, but you can’t stay in that mindset (思维模式) forever. You’ll top out after about three hours, so it’s best to have those three other, smaller tasks lined up and ready to go so you can stay productive even while slowing down into less demanding responsibilities.

6 . In an awe-inspiring incident, a young killer whale recently demonstrated remarkable intelligence by seeking assistance from a group of humans to save its trapped mother, which challenged our conventional understanding of wild predators (食肉动物).
The online viral video, shared by Alvin Foo, began with a young killer whale emitting distressing cries towards a group of people on a boat. Recognizing the urgency of the situation, the concerned individuals promptly responded by contacting a rescue team. The young whale’s desperate request for help touched more people’s hearts and set a truly extraordinary chain of events in motion.
As the rescue team arrived, they were amazed to witness the young killer whale’s playful interaction with the humans. The whale appeared elated, seemingly understanding that assistance had finally arrived. This interaction between the mother killer whale and rescuers underlined the potential for mutual understanding beyond the boundary of traditional predator-prey relationships.
The young whale took on the role of a guide, leading the rescue team to its mother trapped in a fishing net. It navigated the water with purpose, as if fully aware that the humans possessed the means to save its mother. This display of intelligence left the rescuers in awe, highlighting the complex cognitive abilities of these magnificent marine creatures. With its guidance, the rescue team swiftly initiated the liberation process, carefully cutting the net to free the trapped whale. Astonishingly, they seemed to understand that the humans were there to help and did as asked.
The instant the mother whale was finally freed, an eruption of joyous cries filled the air. The emotional outpouring conveyed the immense gratitude of both the mother whale and the young whale to the humans who had intervened. As the rescue team made their way back to shore, the two whales swam alongside them. This heart-warming sight emphasized the lasting impact of the rescue. The bond formed through this extraordinary rescue operation was well obvious, proving that the profound connections can be established between various species. The journey back to safety symbolized the victory of compassion over adversity.

7 . Meteorites (陨石) can offer clues about what the early solar system was like. But finding them is far from difficult. Now, some scientists are turning to drones (无人机) and machine learning to help spot freshly fallen meteorites much more efficiently. “A team of six people on a meteorite-hunting expedition can search about 200,000 square meters per day,” says Seamus Anderson, a planetary scientist in Australia.
Around 2016, Anderson began toying with the concept of using drones to take pictures of the g round to look for meteorites. That idea blossomed into a Ph.D. project. In 2022, he and his colleagues reported their first successful recovery of a meteorite spotted with a drone. They’ve since found four more meteorites at a different site. Drone-based searches are much faster than the standard search way. “You’re going from about 300 days of human effort down to about a dozen or so,” he says.
Anderson and his workmates have used drones to search for meteorites in remote parts of Western Australia and South Australia. The team is tipped off about a fall site by networks of ground-based cameras that track meteoroids flashing through the Earth’s atmosphere. The researchers have to do a series of fun but difficult work before the hunt. They pack a four-wheel drive vehicle with drone and computer equipment, battery charging stations, generators, fuel, food, camping equipment, tables, chairs and much more. The drive to the fall site can take more than a day, often on rough or nonexistent roads. Anderson says, “You hope you don’t pop a tire.”
After arriving, the team flies its primary drone at an altitude of about 20 meters. Its camera takes an image of the ground once every second, and the scientists download the data every 40 minutes or so when the drone lands to receive fresh batteries. A typical day of flying can net over 10,000 images, which are then divided digitally into 100 million or so smaller sections. Those “tiles”, each 2 meters on a side, are fed into a machine learning algorithm (算法) that has been trained to recognize meteorites based on images of real land rocks which are spray-painted black.

8 . Recent research confirms what our farming ancestors have known for centuries about hedges (树篱). They conserve precious soil by acting as windbreaks and absorbing rainwater that would otherwise wash it from the fields. And hedges store carbon, putting them in the front line of our bi d to tackle the climate crisis.
However, hedges have had a tough time in the poor countryside, with farmers encouraged to tear them down in pursuit of maximum production and larger field s to accommodate ever-larger machinery. What’s more, some hedges have been ignored. If left to their own devices, they’ll eventually become a line of trees. Some hedges each year lose their structures and fail to fulfil the primary duty as a barrier. Around a half of the nation’s hedges have disappeared in the past century.
There are signs that “the tide is turning”. The search for net zero has aroused many organizations’ interest in the humble hedge’s role as a carbon sink. The Climate Change Committee is recommending a 40 percent increase in hedges: an additional 200,000 km. Such recommendations are starting to drive policy. Cash-pressed farmers will be encouraged to create new hedges and improve their management of existing ones under the new Environmental Land Management Schemes, which will replace many of the existing agricultural support payments in coming years. Meanwhile, initiatives such as Close the Gap, led by the Tree Council, is providing funding and support to plug the gaps in existing hedges with new planting. There’s even an app to help time-pressed farmers do a quick survey to spot where their hedges need some help.
This is a good time for hedges. Take some of the most pressing challenges facing the countryside, and indeed, the world as a whole — the climate crisis, soil erosion (侵蚀), insect attack and wider biodiversity loss — and hedges are part of the solution.

9 . Let’s get to some famous attractions in London!
Chinatown
At the beginning of the 20th century, many Chinese immigrants gathered together in the East End of London and set about creating businesses to provide services for Chinese people who frequented the area. In the 1930s and 1940s, with a large inflow of immigrants from Hong Kong and a growth in popularity of Chinese cooking style, many Chinese restaurants opened elsewhere.
Natural History Museum
It was ever known as part of the British Museum which was established in 1753. The museum exhibits a large number of cultural relics. It holds collections coming from every continent around the globe. It exhibits millions of life and earth samples, and visitors can witness collections having great scientific value like samples that were collected by Charles Darwin.
Madame Tussauds London
The museum is created by the w ax sculptress, Marie Tussaud. Located on Marylebone Road, it is the first Madame Tussaud’s museum, which opened about 200 years ago, though there are now a variety of other branches within different cities around the globe. The museum hosts lifelike figures, including royal people, film stars, sports stars and models.
Royal Observatory, Greenwich
The Royal Observatory, Greenwich in London, has played a global role in the history of astronomy and navigation. It was established in 1675 with the key function being to set right the places of the fixed stars and find the desired navigational places. With its position overlooking the River Thames in central London, it makes for an excellent tourist attraction on a year-round basis.

10 . Getting rid of(丢弃) old tyres(轮胎) has long been a problem. Every year many tyres are thrown. Some of the ways might be better than getting rid of them, but they are not especially green.
Energy recovery(回收利用) is one common way. This includes burning tyres to produce electricity, or as a way to provide heat for other industrial processes. But that produces planet-warming pollution. Tyres can be whole or broken in construction projects, such as repairing roads. There are, however, worries about chemicals from the tyres coming out and polluting the ground.
So some companies have begun exploring another pleasing idea. Since tyres are mostly made from hydrocarbons(碳氢化合物), it should be possible in principle to turn old tyres into environmentally friendly materials which can be used to run some cars they came from. One of the most thoughtful companies is based in Oslo, Norway. Later this year the company will start building a huge tyre-reused factory in Sunderland in northeastern England. In a couple of years, when the factory is fully operational, it will be able to turn 8 million old tyres into new products.
The process works by dividing a tyre into its three main parts. One is steel, which is used to support the structure of a tyre and which can be easily reused. The second is powder used to improve the continuous use of the tyre. The third is rubber. Some of that will be natural rubber from the rubber trees. The carbon black can be reused to make new tyres. That is of interest to tyre makers because it helps efforts to become carbon neutral(碳中和).
