The swimmers were surrounded by the dolphins for forty minutes before they were able to make them safety back to the beach. It was an uncomfortable experience as they were circled by a group of white sharks, which came within a couple of meters of them. Lifeguard Rob Howes was in the water with a colleague and his teenage daughter. He said around half a dozen dolphins suddenly appeared and forced them to gather together. The mammals swam in tight circles to create a protective wall between the white sharks and the lifeguards as the great white sharks were under the surface.
The swimmers said the dolphins were extremely upset and repeatedly slapped (拍打) the water with their tails as if to try to prevent the white sharks from attacking them. It’s a day they’ll never forget, especially for one who was on her first day as

【推荐1】There may be a reason why astronauts are crazy about the view from space but never mention the food. Astronauts aboard the International Space Station must drink meals out of a plastic squeeze-bag because of zero gravity. Food in space can only be reheated instead of being cooked fresh. Besides, meals for each crew member must be stored in advance and eaten in order. All of this may sound a little difficult to accept.
Therefore, it was one small step for interstellar (星际的) cuisine when U. S. astronaut Megan McArthur recently posted photos of herself holding a pancakes stuffed with beef, tomatoes and a fresh hatch chilli (红番椒) grown aboard the International Space Station itself.
“Best space pancakes yet,” she shared online.
Pesquet, a French astronaut, posted on Instagram, “It is such a joy to grow (and eat) your own food, and necessary for further exploration of our Solar System.” It seems there is a suitcase-sized space garden aboard the ISS (International Space Station) that holds about six “pillows” stuffed with clay and fertilizer, and a LED light. Astronauts have grown several kinds of vegetables including Chinese cabbage and red Russian kale (羽衣甘蓝) in this micro-plot, to test which plants might grow best during a long space voyage.
We called Melva Aguirre, who owns the Pepper Pot in Hatch, N. M., home of hatch chilli. She says the harvest of their famous local crop in outer space is the talk of the town. “Now the whole universe knows how great our chilli are,” she said. When I asked if she could recommend a hatch chilli recipe, Aguirre told me, “Just stuff it.” “Stuff it?” I asked, and she laughed and said, “I mean, in your mouth.” A recipe even I can follow.

【推荐2】While artificial intelligence (AI) technology continues to promote many aspects of human life, it’s now being applied to aiding the protection of giant pandas.
A nature reserve in Northwest China’s Gansu province has built an AI-enabled video monitoring system to better protect giant pandas. Installed with 300 infrared (红外线的) cameras, the monitoring system helps ensure the health and safety of 110 wild giant pandas there. It was put into operation more than two years ago, and has captured numerous photos and videos of pandas engaging in activities such as eating, resting and fighting for mates. It provides scientific data to help us grasp pandas’living conditions and establish conservation strategies. More importantly, it achieves real-time monitoring of the reserve so that we can discern the threats to the wildlife as early as possible. After all, the earlier the problems are found, the easier they may be solved.
A recent study found the monitoring system can automatically recognize various wild animals caught in the infrared cameras, allowing researchers to collect data on giant pandas while staying indoors. It’s shown that by using the AI-aided system to retain the filed photos of giant pandas, researchers obtain a 98% success rate of species recognition. Its success rate of recognizing other wild animals can top 80%. In 2021, this monitoring system captured 2,896 photos of giant pandas and other rare animals and filmed nearly an hour of footage, showcasing the reserve’s sound ecological environment as well as a gradual rise in the panda population there.
Liu Xingming, the head of the reserve’s administration, said researchers used the system not only to observe the dynamics and health of the giant panda population but also to learn about changes in the natural surroundings of their habitat. “The monitoring system has enabled systematic, scientific, and intelligent conservation of wildlife,” he added. “However, it is expected to be further improved and optimized in the near future.”

【推荐3】The moon hasn’t had an easy time over the years. Since the beginning of the solar system 4.5 billion years ago, its gray and lifeless surface has been repeatedly hit by space rocks, leaving behind a landscape full of broken stones. Beneath this surface, however, hide the moon’s most attracting secrets for human explorers, from a large amount of ice for producing drinking water to rocket fuel. More importantly, mapping the moon’s subsurface can show some hidden periods of solar system history. This is confirmed by fresh results from a Chinese rover (月球车).
The latest results come from the Chang’e-4 mission, run by the China National Space Administration. Launched in December 2018 and reaching the moon in early January 2019, the mission became the first to land on the far side of the natural satellite, targeting a region near the lunar south pole called the South Pole-Aitken Basin. The Chang’e-4 rover is still operational today and has been slowly moving across this region, traveling a few hundred meters since it landed.
Using a radar instrument on Chang’e-4, researchers have found that the rover is likely sitting on different layers of ejecta ( 喷 出 物 ) and a very clear order of layers can be seen. The rover’s radar instrument was able to enter up to 40 meters below the surface of the moon, more than twice the distance achieved by the former, the Chang’e-3 mission, which landed on the moon near side in December 2013. Data from the latest mission show three different layers beneath the rover. It is not currently possible to date the layers under Chang’e-4. But they do provide some information about lunar history dating back about four billion years.
The rover is continuing to move across the surface, making regular stops to take measurements and use its instruments.

J.K. Rowling has been spotted at cafes in Scotland working on a detective novel, a British newspaper reported Saturday.
The Sunday Times newspaper quoted Ian Rankin, a fellow author and neighbor of Rowling's, as saying the creator of the "Harry Potter" books is turning to crime fiction.
"My wife spotted her writing her Edinburgh criminal detective novel," the newspaper quoted Rankin as telling a reporter at an Edinburgh literary festival.
"It is great that she has not abandoned writing or Edinburgh cafes," said Rankin, who is known for his own police novels set in the historic Scottish city.
Rowling famously wrote initial drafts of the Potter story in the Scottish city's cafes. Back then, she was a struggling single mother who wrote in cafes to save on the heating bill at home.
Now she's Britain's richest woman - worth $1 billion, according to Forbes magazine - and her seven Potter books have sold more than 335 million copies worldwide.
In an interview with The Associated Press last month, Rowling said she believed she was unlikely to repeat the success of the Potter series, but confirmed she had plans to work on new books.
"I'll do exactly what I did with Harry - I'll write what I really want to write," Rowling said.
