1 . 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.

2 . New research by scientists at the University of Bristol explains how a “stop-start” pattern of evolution,governed by environmental change,could explain why crocodiles (鳄鱼) have changed so little since the age of the dinosaurs.
Crocodiles today look very similar to ones from 200 million years ago. There are also very few species alive today—just 25. Other animals such as lizards and birds have achieved a diversity of many thousands of species in the same amount of time. Prehistory also saw types of crocodile we don’t see today,including giants as big as dinosaurs,plant-eaters,fast runners and snakelike forms that lived in the sea.
The rate of their evolution is generally slow,but occasionally they evolve more apace because the environment has changed. In particular,this new research suggests that their evolution speeds up when the climate is warmer,and that their body size increases.
Lead author Dr. Max Stockdale said,“Our analysis used a machine learning algorithm (算法) to estimate rates of evolution. Evolutionary rate is the amount of change that has taken place over a given amount of time,which we can work out by comparing measurements from fossils and taking into account how old they are. For our study we measured body size,which is important because it interacts with how fast animals grow,how much food they need,how big their populations are and how likely they are to die out.”
The findings show that the limited diversity of crocodiles and their apparent lack of evolution result from a slow evolutionary rate. It seems the crocodiles arrived with an already efficient and versatile (多功能的) body plan that doesn’t require changes. This versatility could be one explanation why crocodiles survived the meteor (流星) impact at the end of the Cretaceous period,in which the dinosaurs died out. Crocodiles generally develop better in warm conditions because they cannot control their body temperature and require warmth from the environment.

4 . Haze (薄雾) and smoke from hundreds of Canadian wildfires covered most of the US Northeast for a second day — Wednesday, with New York City experiencing the world’s worst air quality over the last two days.
New York, the Big Apple became the Big Orange by midday Wednesday as the sky over the nation’s largest city fell into a deep hazy orange. Streets in Manhattan are like what they were like during the pandemic (流行病) as residents again wore masks and cared for warnings from health officials about the impact of PM2.5, which can lead to respiratory (呼吸的) illnesses.
New York Governor Kathy Hochul said on Wednesday that the state was making one million N95 masks available to the public. Approximately 400,000 N95 masks would be distributed at New York state parks, and at subway stations and other locations in New York City, Hochul said at a press briefing. An additional 600,000 masks would be made available at Homeland Security stockpiles (囤聚的物资) for local governments to pick up, she said.
Hochul called the poor air quality “a very serious, dangerous situation”. She recommended that people across the state cancel outdoor activities. “Simply stay indoors. Outdoors is dangerous in just about every part of our state,” the governor said. Officials at the briefing said they had been monitoring any potential rise in respiratory illnesses or health issues due to the poor air quality.
The city’s air was more polluted than all the world’s major cities on Wednesday morning, according to data from Swiss technology company IQAir. Dubai and Delhi came in second and third, respectively. Mike Hardiman, a staff in the National Weather Service, told The New York Times the city “smells like cigars”.

6 . From Jilly Cooper to Winston Clurehill, horse riders have long supported the emotional benefit of the human-horse bond. Hernan Melville, the author of Moby Dick, once argued: “No philosophers so thoroughly comprehend us as dogs and horses.”
When it comes to dogs, we have no doubt about it. But horses can tell when a human being is feeling unhappy, a study has found, although whether or not they care remains an open question.
The latest study, published in the journal Animal Cognition, sought to correct this. The question the researchers wanted to answer was; do horses understand a range of human emotions? To investigate this, they employed a technique often employed in studying baby cognition (认知); they showed the horses something that made no sense, and watched to see whether it puzzled them. One after another, the scientists put 28 horses in a room. Each horse was shown two pictures of the same person at the same time. In one picture the person had a happy face, in the other the person had a long face. At the same time they heard either a happy or sad voice.
From a human perspective, only one of the pictures made sense — the one with a voice that corresponded to the image. The other was “incongruent (不一致的)”. Were the horses similarly confused? It appears they were. What the scientists found was that on average the first time the horses saw the incongruent image, they spent longer looking at it.
Oceane Liehrmann, from the University of Turku in Finland, said this implied a level of emotional and cognitive complexity that we may not always credit to horses.
We don’t know whether horses themselves understand what it is to be sad, or experience the emotion. What the research suggested was that, however, it is possible they learn that it means something for a human — and that when we are sad they expect what we say to match how we look.

7 . Four Beautiful National Parks in New Zealand
Fiordland National Park
With over three million acres, the Fiordland National Park is the largest in New Zealand. It is also one of the most popular tourist attractions, drawing hundreds of thousands of visitors yearly to its dramatic landscape. When visiting, you will find beautiful fiords (峡湾), ancient rainforests, shining lakes, waterfalls, and snow-capped peaks.
Abel Tasman National Park
Located on the north end of the South Island is Abel Tasman National Purk, named after the first European explorer to find New Zealand. At nearly 60,000 acres, it is the smallest national park in the country, but it offers the perfect mix of relaxation and adventure. For instance, the park features sandy beaches, clear streams, forested hills, and mossy valleys. The best way to experience the area is by hiking, camping, kayaking, sailing and swimming.
Arthur’s Pass National Park
Also on New Zealand’s South Island is Arthur’s Pass National Park, featuring primarily mountainous terrain (地形). Arthur’s Pass includes the heart of the Southern Alps and consists of high, rough mountains, steep gorges and wide rivers. Because the area is not as developed as other parks and requires visitors to have a knowledge of route-finding and river-crossing, it is not typically an area for inexperienced recreationists.
Tongariro National Park
Tongariro was the 6th national park established in the world and the oldest in New Zealand. It’s been open to the public since 1887 and is the perfect destination for thrill-seekers and those who appreciate mother nature. The park contains three active volcanoes and features world-famous crossings for some of the best hiking and skiing in the world.

8 . In a joint effort to tackle the climate crisis, humans are turning to offshore wind farms (OWFs) as a source of renewable energy. OWFs are, quite literally, one of the biggest forms of renewable energy. The world’s largest OWF covers an area of 462 square kilometers, with each turbine (涡轮) standing 200 meters above the sea. It has the capacity to power over 1.4 million homes. But what impact do the towering turbines have on life in the waters below and the skies above?
It’s thought that OWFs could affect marine (海洋的) life in a number of ways, from noise disturbing the behaviors of fish and whales to changes in the diversity of species in the area. Seabirds that live in the North and Baltic Seas — where a vast majority of OWFs are placed — are also thought to be endangered by turbines. A report from Bird Life International found that twelve North and Baltic seabird species were at high risk of crashing with farms and seven at high risk of being displaced by their construction.
Not all impacts are negative though — some research has suggested that OWFs have the potential for environmental benefits too. A study following the movement of gray seals in the North Sea found that they were frequent visitors to two OWFs, searching between turbines for food. The researchers suggested that farms be acting like artificial reefs, representing a new and concentrated source of food. In areas where marine life has become less dense, it could allow life to flourish (繁荣) once again.
Even so, researchers explained that it’s difficult to predict the full extent of the potential environmental outcomes from these unexpected artificial reefs: “Only a small proportion of our study seals used wind farms or pipelines,” study author Deborah Russell told The Guardian at the time.
To avoid replacing one problem by creating a new one, it seems that researchers and developers will have to continue working hand in hand to ensure OWFs and marine life can successfully live side by side.

9 . 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.

10 . 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.
