1 . LONDON (Reuters) — Quiet place — Britain’s Queen Elizabeth is preparing to have her swans counted.
Buckingham Palace has announced that the annual Swan Upping, a tradition dating back to the 12th century which involves a census (审查) of the swan population on the River Thames, will be conducted by the Queen’s official Swan Marker from July 20 to 24.
“With the assistance of the Queen’s Swan Warden, Professor Christopher Perrins of the University of Oxford, the swans and young cygnets (小天鹅) are also assessed for any signs of injury or disease,” Buckingham Palace said in announcing the count.
The process involves the Swan Marker, David Barber, rowing up the Thames for five days with the Swan Warden in traditional skiffs while wearing special scarlet uniforms and counting, weighing and measuring swans and cygnets.
It may seem odd, but it is very important to the Queen. According to custom, Britain’s sovereign owns all unmarked, mute swans in open water, but the Queen now exercises the right only on stretches of the Thames and its nearby tributaries.
In medieval times, the Swan Marker would not only travel up the river counting the swans, but would catch as many as possible as they were sought after for banquets and feasts.
This year, the Swan Marker and the Swan Warden are particularly keen to discover how much damage is being caused to swans and cygnets by attacks from dogs and from discarded fishing tackle (渔具).
It is also an important year because Queen Elizabeth has decided to join her team of Swan Uppers for part of the census. She will follow them up the river and visit a local school project on the whole subject of swans, cygnets and the Thames.
“Education and conservation are essential to the role of Swan Upping and the involvement of school children is always a rewarding experience,” Buckingham Palace said.

2 . Each spring, millions of people take photos among the famous cherry trees around the Tidal Basin in Washington DC-some even get married there. That’s what Jody Axinn did 10 years ago.
“Now, the romantic spot is unrecognizable. The whole section is under water,” says Axinn who is revisiting the cherry trees with her family. “When I got here 10 years ago, the place was flooded regularly, but certainly not twice a day, every day.”
There are two forces working together to affect the Tidal Basin, the trees and monuments around it. The seawall around the basin, built with mud dug up from the Potomac River bottom, has sunk about five feet over the past century.
“At the same time, the water level in the basin has gone up by more than a foot because of climate change,” explains Leslie Frattaroli, manager of the National Park Service (NPS). “The Tidal Basin looks like a small lake, but it’s actually part of the Potomac River, because there are gates at the upstream and downstream ends of the basin that allow river water to rush through. Therefore, it is gradually rising along with the level of the world’s oceans.”
Combining these two factors, the water is six feet above where the seawall was originally designed to keep it out. Later this spring, the park service will start to raise parts of the walkway around the basin and along the Potomac River.
“It would be impossible to complete the $113 million project without removing the cherry trees along the water,” Leslie says. “The good news is that when the project is completed in 2027, 274 new cherry trees will be planted.”
Among the trees to be removed is a very famous little tree known as “Stumpy”. At high tide (潮汐), the base of the tree is flooded. Although it is in extremely bad conditions, its remaining three or four small branches burst into flower each spring, with the Washington Monument standing tall in the background.

3 . Having studied more than 400 groups of honeybees in Brazil for two years, a group of biologists led by Viviana Di Pietro report that, like humans, honeybees are capable of learning new traditions which are then handed down over generations.
“The most obvious example is that honeybees can build their homes according to different architectural traditions which are then handed down over generations,” they write. “We found that around 95% of the honeybees built their homes in a horizontal (与地面平行的) style, while 5% of them preferred a spiral (螺旋形的) structure. In each case, the tradition was passed down to the next generations.”
Since honeybees showed a strong preference for a horizontal structure, it was surprising that spiral structures occurred at all. “With the help of video cameras, we found that there was a noticeable difference in average building rate between the two styles.” the researchers add.
In order to rule out a genetic (遗传的) explanation for the different styles, the researchers took honeybees from the groups that built in spiral tradition close to the groups that built in horizontal tradition. The imported honeybees soon learned to build their homes in the local style, which was then passed down to their children as they eventually grew up. “It is very likely that the imported honeybees might have changed the style as a way of correcting the construction errors made by their ancestors.” the researchers suggest.
The findings have surprised observers of animal culture, as they suggest that honeybees can learn and hand down different building traditions over generations. This has changed the way of thinking about culture, which is often strictly defined as behaviour directly handed down from human parents to their children until it becomes a tradition in a group.
“Insect culture was thought impossible. Less than a century ago, culture was thought to be uniquely human,” says biologist Andrew Whiten of the University of St Andrews, who was not involved in the research. “But the new research has offered strong evidence pointing to the opposite.”

4 . The Atacama Desert in northern Chile stretches from the Pacific to the Andes across an expanse of red-orange rock mountains and peaks. It’s a dream destination for tourists. But the Atacama Desert is also one of the world’s fast-growing dumps (垃圾场) of abandoned clothes. The scene in northern Chile has been shown in one online video-large amounts of abandoned clothes stretch as far as the eye can see.
Chile is home to one of South America’s largest duty-free ports-located in the coastal city of Iquique. The duty-free port was established in 1975 to help generate jobs and improve local economy. As fast fashion exploded, so did imports. Millions of tons of clothes arrive annually from all over the world.
“The free zone was a ’true transformation’ for the city’s residents,” says Bernardo Guerrero, a sociologist that studies Iquique’s history and culture. “They suddenly had access to things they could never have imagined.” Clothing began washing in and out of Iquique like waves as global fashions changed. Guerrero recalls a time when almost everybody in the city wore the same style of puffer jacket.
The free zone has also developed into a sorting site for abandoned clothes. Mehmet Yildiz, who operates a clothing import business, brings in clothes from the United States and Europe. Once the clothes reach Iquique, workers separate them into four categories according to quality. Yildiz then exports the best to other countries for resale. Clothing that the importers don’t want will be delivered a few miles outside Alto Hospicio, where it goes through another cycle of sorting and resale in street markets. Clothing that doesn’t sell at the market is sent to the desert, and much of it is made from materials that won’t biodegrade (生物降解).
As helpful as resale markets might have been in an earlier era, they’ve been flooded with the large amounts of the mounting discards. New efforts, large and small, are under way to deal with clothing waste, and attention to the mess in the desert may inspire additional projects.

5 . “Earth” has always been an odd choice of name for the third planet from the Sun. After all, if an alien examines it through a telescope, he would note that two-thirds of its surface is covered not by earth at all, but by oceans of water.
However, most of the oceans on Earth remain unexplored. For example, photographers are fond of pointing out that scientists have mapped nearly all the oceans’ surface, but less than a quarter of the seabed. Biologists think the oceans might host more than 2 million species of animals, of which they have so far identified perhaps a tenth.
A new project may change this. Launched in London on April 27th, 2023, Ocean Census aims to discover 100,000 new species of ocean animals over the coming decade. Its first ship, Kronprins Haakon, set sail on April 29 for the Barents Sea.
The project is launched for two reasons. One is that the longer scientists wait, the less there will be to study. “Top on our agenda are species thought to be in the greatest danger from climate change,” says Oliver Steeds, founder of the project. “Otherwise, the forest is burning down and we won’t know what was there before it is lost.”
The second reason is technological. Biologists find about 2,000 new species a year, a rate hardly changed since Darwin’s day. Ocean Census is betting that it can go faster. Fancy cameras on remote-operated vehicles, for instance, allow scientists to scan deep-sea creatures such as jellyfish without removing them from their habitat. Just as the huge pressures of the deep sea are deadly for humans, taking such a jellyfish to the surface for examination may reduce it to gooey slime (黏液).
Exactly what the new effort might turn up, of course, is impossible to predict. But history suggests it will be fruitful. Half a century ago, scientists discovered hot seabeds that were home to organisms living happily in conditions that, until then, had been thought harmful to life. These days, such hot seabeds are thought to be one possible candidate for the origin of all life on Earth.

7 . For uncounted generations, trillions of coral polyps (珊瑚虫) have lived and died, leaving behind a material called limestone. Throughout History, limestone was used to construct the Great Pyramid of Egypt, as well as many churches and castles.
Indeed, a living coral reef is remarkable, a “city beneath the sea” filled with a rich variety of life. Most coral reefs can be found in warm, shallow oceans. They occupy just a small part of the ocean floor, but host 25 percent of all ocean life. Each reef is full of colorful fish as well as coral that forms wonderful patterns. In addition to their beauty, the reefs are an important food source for fish, and for. humans.
Threats to coral reefs
Reasons for hope
These threats to coral reefs are very serious, but there is reason to hope that they will survive. If we take steps toward coral reef conservation, it is likely that these tiny creatures — which survived natural threats for millions of years — will be able to rebuild. As conservationist Robert Richmond says, “
| A．A diversity of life |
| B．A city above the sea |
| C．Given a chance, they can come back |
| D．Yet the greatest limestone structures in the world are built underwater |
| E．Various human activities can cause great harm to the world’s coral reefs |
| F．As a result, the fish became stunned, which makes them easy to collet. |
| G．This kills most living things nearby and causes damage to the reef’s structure |
8 . Have you ever paid attention to the color of the airplane seats? They’re almost always blue and there are very few exceptions to this rule. Some people think it reminds us of the sky. But the explanation isn’t that simple!
It is calming.
Color psychology plays an important role in selecting the fabric for airplane seats. “The idea is to help passengers feel at home, with relaxing colors and restful designs,” explained Shelly Zundell in a Boeing press release.
In a study reported by Popular Science, 48 percent of participants thought soda in a blue glass was more thirst-quenching (解渴的) than that served in glasses of other colors, probably because they connected blue with cold. Colors such as red and orange can make people feel warmer. Although it’s not unheard of, red is a less common color for airplane seats.
It is a universally well-liked color.
The right shade hides stains (污渍) well.
Dark blue seats are also just practical. Imagine how many people sit in them per day.
Darker shades are better at hiding stains and don’t show their wear as easily. Those dark blue seats will look fresher and newer for longer.
| A．It physically feels cooler. |
| B．It reflects a cool professionalism. |
| C．But is there any other explanation? |
| D．And who knows what gets spilled on them? |
| E．People often connect certain colors with certain feelings. |
| F．Feeling hot when you board an airplane is good for no one. |
| G．It’s hard to find someone who has strong feelings against the color blue. |
9 . The ocean depths contain the metals needed for the widespread use of battery-dependent technologies like electric vehicles, which will help reduce greenhouse gas emissions. Interested parties see this as a solution to our technological demands and the pressing need for a “green transition”. However, it raises a crucial question: should we mine the deepest stretches of the world’s oceans?
Some scientists and activists warn that seabed mining could cause an irreversible (不可逆的) chain reaction, severely harming the ocean and threatening entire ecosystems on the ocean floor. There are also potential risks to our health, including toxic metals entering the human food chain, and affecting climate change. The most significant direct impact of mining in remote ecosystems is the probable loss of habitat and biodiversity.
Dr Chong Chen is a deep sea biologist at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC). “There are undoubtedly many undiscovered species with abilities and functions that we cannot even imagine exist,” he says, “and we could lose them without knowing they ever existed.”
The mining process also disturbs seabed sediments (沉积物) and releases them back into the sea, raising additional concerns among scientists. Mining is for metals, whose stability of the construction are unchecked. “Some of those may be broken down and be directly into the water column,” says Jeffrey Drazen, professor of Oceanography with the University of Hawaii at Manoa. “Some of these metals are toxic to life.” says Professor Drazen. At the same time, he acknowledges the core challenge is ensuring whether the benefits of extracting (提取) deep-sea mineral resources outweigh the potential harm to our ecosystem. He notes that it’s a tough choice.
The positive development is that, for the first time, companies, governments, and civil society are actively participating in international discussions to create rules and regulations for the deep-sea mining industry before it begins.

10 . Despite the difficulties, the California coastal ecosystem is improving, largely thanks to the huge appetite sea otters (海獭) have for crabs. In a creative study, scientists revealed the return of otters to their former habitat in a Central California river mouth has slowed the decrease of the area’s river banks by up to 90%. “It would cost tens of millions of dollars for humans to rebuild these stream banks and restore these rivers. The otters are stabilizing them for free, in exchange for an all-you-can-eat crab feast,” said biology professor Brian Silliman, Ph. D. at Duke University.
Like many California river mouths, Elkhorn once was a habitat for otters, which need to eat around 20 to 25 pounds of food every day, with crabs being one of their favorite meals. But after fur traders hunted the local otter population nearly to extinction, the number of crabs exploded over the next century. Crabs dig into salt river soil, and over time can cause a salt river to wear away and collapse. Today, years after the otters returned, rivers and stream banks became more stable.
Angelini, one of the study’s authors, said that tool is an encouraging sign for her team as they face similar threats to Florida’s coastlines from sea level rise, storms, and extra nutrients overflowing into coastal waters. “All these seem unsurmountable,” Angelini said. “However, this study shows that, if we truly understand the ecosystem and know what tools to use, we can see significant benefits to the health and stability of these systems.”
The research team conducted large-scale surveys across 13 tidal (潮汐的) streams, as well as small-scale field experiments at five locations around the river mouth over a six-year period. Otters were not included in some lest sites but allowed to be used in others, using a caging system designed by Angelini.
“And all these years later, we now see these amazing results. It’s an inspiring story about the benefits of conservation and persistent, long-term research,” Angelini said.
