2 . A team of scientists is studying the sound of the forest in Ecuador to learn how artificial intelligence (AI) could follow animal life in recovering environments.
When scientists want to measure new forest growth, they can study large areas of land with tools like satellites. But understanding how fast and in what number wildlife is returning to an area is more difficult. Sometimes it requires an expert to listen through sound recordings and pick out animal calls.
Jorg Muller, an expert on birds, wondered if there was a different way. So, he turned to bioacoustics (生物声学), which uses sound to learn more about animal life and their living environments. Muller and his team recorded wildlife sounds in Ecuador. They first had experts listen to the recordings and list the sounds of different animals. Then, they examined the sound quality to measure the environment. Finally, they ran two weeks of recordings through an AI computer program trained to understand 75 different bird calls.
The program was able to pick out the calls on which it was trained. However, scientists wondered if the program could correctly identify the number of different kinds of plants and animals in each environment. To see if the program could do that, the team used two different controls. One was from the experts who listened to the recordings, and the second was based on examples from each environment, which can be used to understand biodiversity (生物多样性).
Since the number of sounds that are found to be used to train is limited, the AI program could only identify one-fourth of the bird calls experts could. But it was still able to correctly measure biodiversity levels in each environment, the study said. It also said the results show the AI program is a powerful tool to measure the recovery of animal societies in some forests. The study showed that biodiversity found from recordings can be measured in a cost-effective and complete way and measure environments.
There are still areas for improvement, including the lack of animal sounds on which to train AI models. And the method can only catch animals that use sound to communicate.

4 . For Cruz, who grew up in Peru’s mountainous region of Cuzco, fog represents a massive opportunity. As a boy, he had to hike for more than an hour every day across hills to collect water from the nearest source. But over time, he realized that during the rainy season, droplets of water would gather in the large leaves of banana trees. So one day he and his father tried to build a canal system with the leaves to collect water and it turned out a success. But afterwards, he moved to Lima at the age of 25.
There, shocked by the water shortages and expensive water supply that some of the city’s poorest residents were faced with, Cruz set up El Movimiento Peruanos sin Agua in 2005. The idea was to deploy the method he learned in his hometown on a larger scale, which would provide free, independently sourced and easily accessible water to those who needed it most. He began installing (安装) a traditional fog catcher model developed in the 1980s.
At the highest point of Los Tres Miradores, there is a curious set of large structures that resemble a fleet of ships in the sky. They are so-called “fog catchers”. Netted devices, made of high density Raschel polyethylene and spanning several meters wide, are lined up at the top of a misty mound and linked by a network of tubes that lead to storage containers. The 40 fog catchers there provide enough water for 180 families, whether to bathe, clean, drink or to irrigate crops on small garden patches.
Supporters believe that fog catchers have the potential to improve water supply for communities around the world among the ever-challenging circumstances. German researcher Lummerich says, “They are cheap, easy to construct.” In a world searching for water supply systems, it is one important puzzle piece that can make an essential difference locally.
However, there are some issues. For one, fog catchers require space, which is not always easy to come by in cities, let alone urban slums. At the same time, fog catchers must be properly cleaned and maintained to stay effective. Most crucially, appropriate climate conditions are required. Fog isn’t everywhere.

7 . How to write tip-top articles
Articles, like all pieces of writing, can be divided into three sections, a beginning, a middle and an end.
The middle is the biggest part, and from the reader’s point of view it’s the most important — it is where the content lies.
Endings are as important as introduction, and for the same reason. They are your last chance to impress readers and editors.
The best way to get good at intros and endings is to read a lot of them in a wide variety of magazines and newspapers.
All the above considered, you are bound to write excellent and impressive articles.
A.It’s also the easiest bit to write. |
B.You will keep your writing fresh. |
C.Beginnings, by contrast, can be more difficult to do well. |
D.If you seize it, the editors may keep coming back to you with more work. |
E.That means writing a lot of good beginnings and ends that editors and readers appreciate. |
F.So you should conclude the piece with a flourish (华丽辞藻), or a satisfying sense of completion. |
G.Whenever you come across one that grabs your attention, copy the style in your own article. |
8 . Honeybees are in trouble. While they’ re crucial for promoting biodiversity and producing food for healthy human diets, honeybees face many threats, including habitat loss, climate change, air pollution and disease-causing organisms.
But now, there’s hope for helping honeybees fight back against one of the many stressors they face, a deadly infectious disease known as American foulbrood. To fight the disease, the U.S. Department of Agriculture approved for use the world’s first honeybee vaccine (疫苗), developed by Dalan Animal Health.
Bacteria called Paenibacillus larvae cause American foulbrood, which kills honeybees while they are in the pupal (蛹的) or pre-pupal stage. Until now, there was no “safe and sustainable” way to prevent American foulbrood. The only treatment involved antibiotics (抗生素), which are expensive, have limited effectiveness and take lots of time and energy for beekeepers to apply. To stop the spread, beekeepers are often forced to burn infected bees. That makes the vaccine a game changer.
“Our vaccine is a breakthrough in protecting honeybees,” says Annette Kleiser, CEO of Dalan Animal Health. “We are ready to change how we care for insects, impacting food production on a global level.”
Beekeepers will mix the vaccine, which contains dead P. larvae bacteria cells, into the food that worker bees eat. Then, when the worker bees produce their milky royal jelly (蜂王浆), the queen will eat it and the vaccine. Then, the vaccine will protect her developing offspring from the disease.
Under a conditional license from the USDA, Dalan Animal Health now plans to distribute limited amounts of the vaccine to commercial beekeepers. From there, they hope to offer it for sale throughout the U.S. sometime this year.
The federal agriculture agency awards conditional licenses to products that meet an emergency, situation, limited market, local situation or special circumstance. The USDA requires products that receive these types of licenses to be pure and safe, and have a reasonable expectation of effectiveness. Generally, conditional licenses come with restrictions and cover a limited period of time. Once that period ends, the agency evaluates the product’s effectiveness to determine whether to renew the conditional license or award a regular product license.

Jane Brown sat carefully putting papers into a folder. She had been at the Gateway Nature Center’s office all morning and was tired of filing. She wanted desperately to work with the animals. She had been a weekend volunteer that whole school year and had done extensive research, reading books and websites on natural history. But her mom, who was the assistant director of the center, said Jane was still too young.
Suddenly, the quiet was broken by Amy bursting in. She had been a volunteer a bit longer than Jane and wandered around like she owned the place. “Hurry up, Jane,” she ordered. Jane willed herself to remain still and just smiled back.
Just then, Jane’s mother rushed into the room with Mr. White, the manager. “The hurricane is now approaching the Gulf Shore Preserve,” Mrs. Brown reported. “It needs help preparing for it. I have to go down there with the staff. We’ll take the bridge, so we shouldn’t be gone long. I need you girls to help Mr. White get the storm shutters (护窗) down in the aviary (鸟舍). Then, stay inside with Mr. White. Call me on my cellphone if there’re any problems,” Mrs. Brown directed as she rushed out. Jane was excited to have an opportunity to help the birds.
Amy announced she was now “in charge”. Jane smiled again, saying nothing. Mr. White and the girls worked quickly and were soon back inside. But when Mr. White called Jane’s mother, a worried expression crossed his face. “A storm has flooded the bridge, and they’re stuck there. Also, the storm is heading our way,” he said. Amy was frightened. After silently considering for a few seconds, Jane said calmly, “We should move the birds to the reptile house (爬行动物馆). It’s on higher ground.” Mr. White and Amy nodded. They rushed out of the building. Once inside the aviary, Jane watched Amy lunge (猛冲) from cage to cage.
