1 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

2 . An advance in electronic publishing could make the e-book you are reading seem as dated as a silent film. Publishers hope to explore the growing success of e-books by releasing versions with added soundtracks（电影配音）and musical accompaniments.
The noises in the first multimedia books — released in Britain on Friday - include rain hitting a window in a Sherlock Holmes tale. When the plot of a book reaches the most exciting part, background scores will create tension.
Supporters argue that sound effects are the next logical development for e-books and will add excitement for younger readers. Critics, however, will argue that the noise will ruin the simple pleasure of having the imagination stimulated by reading.
Caroline Michel, chief executive of the literary agency, said the new generation of computer- literate readers was used to multiple sensory input. She said, “Young people have split computer screens where they may be watching television and replying to an email at the same time. If that's what the market wants then we should respond to the market.”
Book track's sound effects work by estimating the user's reading speed. Each lime you turn a page, the software reassesses where you have reached in the text and times the sounds to switch on accordingly. If the soundtrack becomes out of synch （同步），a click on any word will reset it.
Some authors fear that a soundtrack could destroy the peace and quiet of libraries and ruin the pleasure, of reading. David Nicholls, author of Our Day, the bestseller now released as a film, said, “This sounds like the opposite of reading. I have enough trouble reading an e-book because I'm constantly distracted by emails.
Stuart MacBride, the crime writer whose novel Shatter the Bones was an e-book bestseller, sells 18% of his books as electronic downloads. He said, “If I'm reading, I will do the noise in my head. I don’t need someone to tell me what lea cups clinking sounds like. That would irritate （激怒）me.”

3 . Covid-19 has brought a great deal of trouble for all of us since March 2020. During this time, mobile phones have been the solution for the boredom and restlessness caused from staying indoors. The most downloaded apps on play store 2020 are;
TikTok
TikTok was the most downloaded app. With over 111.9 million downloads, TikTok has seen a huge growth in 2020, twice more than what it got in 2019. 20% of its total downloads were from India and around 9. 3% of the total downloads were in the US.
Zoom
Zoom was the second most installed app in the overall downloads category. With nearly 94. 6 million installs, Zoom is the most used app for online meetings and virtual classrooms. 17% of its downloads were in the US and India. Offices and educational institutes were shut down and to continue working and studying from home, people relied heavily on Zoom for video conferencing and calling.
WhatsApp ranked third in overall downloads with more than 100 million downloads. It is one of the most popular and widely used chat applications; WhatsApp also supports communication between international phone networks.

4 . Few people realize that it takes the army of volunteers for one young child to have a half-hour riding lesson. I volunteer at Valley Therapeutic Equestrian Association (VTEA) in Alder grove. B. C. , close to the Washington State border. It takes a few paid staff and an army of volunteers-approximately eighty-to take care of a dozen horses and help with eighty or more children during the week. There is a large barn to clean, and hay nets and water buckets to brush and fill. Specific feeds for each horse must be prepared twice daily…. The list is endless.
To prepare a horse for a ride, someone has to bring it in from outside, at times sinking into inches of black, sticky mud during the winter months. Usually, two volunteers groom (刷洗梳毛) the horse and put on the special saddle. Then they lead the horse to where the lesson takes place. There, one volunteer leads the horse, and usually two walk alongside for safety, one on each side. Then the horse must be returned to the barn, unsaddled, cleaned and fed.
Yet so many people willingly give their time-because the children need us. Ranging in age from two upwards, the children have varying degrees of mental disabilities. Some have severe physical handicaps (残疾). Riding strengthens their muscles and bones, enabling them to enjoy a more fruitful life.
Throughout my past life as an accountant, business author and speaker, I volunteered on many levels and in many organizations. However, a terrible motor-vehicle accident changed my life in a split second when my car was hit—as was my head——causing severe brain injury. It was hard to accept a new "me" and her often-frustrating limitations, until I discovered that I needed to do something that I have a passion for. I’d loved horses from childhood, and working with them and with the children has helped turn my life around, making me warm from the inside out. The journey back has been painful but worthwhile. Now, fourteen years later, I am a different, more simplified person.

5 . You’ve heard the predictions from some of the brightest minds about AI’s influence. Tesla and SpaceX’s chief Elon Musk worries that AI is far more dangerous than nuclear weapons. The late scientist Stephen Hawking warned that AI could serve as the “worst event in the history of our civilization” unless humanity is prepared for its possible risks.
But many experts, even those who are aware of such risks, have a more positive attitude, especially in health-care and possibly in education. That is one of the results from a new AI study released Monday by the Pew Research Centre.
Pew canvassed the opinions of 979 experts over the summer, a group that included famous technologists, developers, innovators, business and policy leaders. The interviewed experts, some of whom chose to remain anonymous, were asked to join in the discussion of a serious and important question: “By 2030, do you think it is most likely that advancing AI and related technology systems will improve human capacities and control them?”
Nearly two-thirds of experts predicted most of us will be mostly better off. But a third thought otherwise, and a majority of the experts expressed at least some concerns over the long-term impact of AI on the “essential elements of being human”. Among those concerns were data abuse, loss of jobs and loss of control brought by autonomous weapons and cybercrime. Above all, by taking data in and spitting answers out, those “black box” tools make decisions in digital systems. It is an erosion in our ability to think for ourselves.

6 . Some termite (白蚁) species have figured out how to enjoy the shelter of the huge complex nests that the insects build without contributing to their construction. They avoid the full anger of their builder hosts by being extremely easy-going.
Animals that live in the nests of another species without affecting them are known as inquilines. Inquiline termites are unique among termites in being unable to make their own nests. Instead, they live in the hallways built by another termite, Constrictotermes cyphergaster. Until now, it has been unclear how the two parties kept peaceful in such tight quarters because termites are typically very aggressive towards outsiders.
Helder Hugo at the University of Konstanz in Germany and his colleagues collected Constrictotermes cyphergaster’s nests in the Brazilian Cerrado and brought them into the laboratory. They then placed host and tenant (房客) termites in either open or narrow areas and used video to track and record the ways in which the two species reacted to each other.
Right from the start, the inquiline’ termites moved around less than their hosts and interacted little with them, even in the much narrower area. “Many times,” says Hugo, “when two unrelated groups are put together in a limited space—such as an experimental area—the outcome is conflict with losses from both sides.” But that didn’t happen here. Despite attacks from host termites, the tenant termites were obedient. Hosts would bite or attack the inquilines with strong chemicals, but their targets never responded in the same way, choosing to flee. Some ignored the hosts completely.
“We did not expect that they would never fight back,” says Hugo, noting that the inquilines are capable of protecting their own place with mouths. “By preventing conflict going worse, inquiline termites may considerably improve their chances of living together with their host termites peacefully.”
“Passiveness does not necessarily lead to defeat, but can be a very useful strategy, saving energy and resources,” she adds. “Nature may not always be red in tooth and claw, and aggression is not any more successful a strategy than ‘cowardice’ (儒弱).”

7 . A new device works like a solar panel, except that it doesn't harvest energy from the sun. It absorbs energy from the cold night sky.
A prototype(原型)of the device produced enough electricity at night to power a small light bulb. A bigger version might one day light rooms or charge phones. It also could power electronics in remote or low-resource areas that lack electricity.
The device makes use of the temperature difference between Earth and outer space.It then uses that difference to create electricity. As long as one side of it is cooler than the other, the generator can produce electricity.The cooler side faces the sky and is attached to an aluminum plate. That plate is sealed beneath a transparent(透明的)cover and surrounded with insulation(隔热材料)to keep out heat.The bottom of the generator is attached to an exposed aluminum plate. That plate is warmed by the local air. At night, the top plate can get a couple of degrees Celsius cooler than the bottom of the generator.
Researchers tested a 20-centimeter prototype one clear December night in Stanford,California. The generator produced up to about 25 milliwatts of power per square meter of device. That was enough power to light a small light-emitting diode, or LED bulb. Further improvements might increase its production to at least 500 milliwatts per square meter. To do that, the system might need more insulation around the cool top plate.
The device also could help power remote weather stations or other environmental devices,says Aaswath Raman. He is a materials scientist who worked on the device at the University of California, Los Angeles. This may be useful in polar regions that don't see sunlight for months at a time,Raman says. “If you have some low-power load and you need to power it through three months of darkness, this might be a way.”

8 . A work of art created by artificial intelligence (AI) has been sold by a major art seller for the first time. The print sold for an unexpectedly large amount of $432, 500. The artwork was bought during an auction (拍卖) Thursday at Christie’s, an art house, in New York City. Officials had predicted it would sell for between $7, 000 and $10, 000.
In a website post, Christie’s said the AI-created work was the first ever sold by a major auction house. It praised the sale as a signal of “the arrival of AI art on the world auction stage.”
The artwork, called “Portrait (肖像) of Edmond Belamy,” was made by a machine learning algorithm (算法). The AI system was created by members of an art group called Obvious in Paris, France. It shows the portrait of a man, looking similar to subjects shown in historical paintings. Christie’s described some differences of the AI-created work compared to other art it sells. For example, it said some parts of the face were not as clearly drawn as those painted by artists. Also some parts of the print were left empty. However, Christie’s sale organizer Richard Lloyd said the piece was very similar to many others sold over many years.
Three creators from the art group Obvious cooperated on the process that made the print. First they put a collection of 15,000 portraits into a machine learning system. The portraits were painted by artists from the time period between the 14th and 20th centuries. Then a tool called the “Generator” made a new image based on the information entered into the system. After that, another tool, called a “Discriminator”, attempted to find differences between the human-made image and the one created by the Generator. Then the image was improved. “The aim is to fool the Discriminator into thinking that the new images are real-life portraits. Then we have a result.” Obvious group member Hugo Caselles-dupre said in a statement.

9 . As I stuck in the mud (泥), with my bike on top of me, I wondered what had forced me to come here. Madagascar is not a good place for a cycling holiday: one of the world's poorest countries, only 11 percent of roadway is paved (铺). South of the town of Antalaha, where I started, the road was in worse condition.
I appeared from a week in the wilderness and reached the start of the Route National 5 at Maroantsetra, but my dream of a smooth road and speed was suddenly destroyed by mud. The "worst road in the country" changed my bicycle into a burden (负担) for days. Finally, I was claimed by the road. Tired. Alone.
As I wiped (擦) the mud from my face and looked upwards, I was greeted by a Malagasy man. He helped me stand up and smiled playfully while he pointed to my bike, which sat next to his. I started again. But I fell again in the mud. Angrily, I told him to go on, but if he understood he showed no sign of it. His smile forced me back onto the bike. We continued like this for hours. But I fell less. Studying my quick guide, slowly I learned. As we passed through a village, a group of children saw me and shouted loudly. His only words were: "Their parents tell them while people steal and eat them. Funny, no?"
I tried to ask why, but he had already set off. I tried to catch up; as I got closer, he took it as a challenge and sped up. We raced along the road. I rode a little faster and I was just behind, about to catch up with him. With a smile, he sped up and was away, leaving me breathless.

10 . Alexa is Amazon’s cloud-based voice service available on hundreds of millions of devices from Amazon and third-party device manufacturers. With Alexa, you can build natural voice experiences that offer customers a way to interact with the technology they use every day.
Alexa is always eavesdropping (窃听). (So are Siri, Google Assistant, and any other virtual assistant you invite into your home.) This is and isn’t as horrible as it sounds. Although it’s true that the device can hear everything you say within range of its microphones, it is listening for its wake word before it starts recording.Once it hears that —“Alexa” is the default (默认), but there are other options — everything in the following few seconds is considered to be a command or a request and is sent to (and stored on) servers in the cloud, where the correct response is triggered. Think of a smart speaker like a dog: It’s always listening, but it understands only “cookie,” “walk,” or “Buddy.” Everything else goes right over its head.
Every time Alexa hears a command, Amazon — its parent company — has just learned something about you. Maybe the company learned only that you like to listen to the Police, or that you like funny jokes, or that you turn your lights off at 11 p.m. every night. If you were to say “Alexa, where should I bury the body?” you’re not going to have the police showing up at your door. (I know because I’ve tried it.)
Alexa does make mistakes.Sometimes this can be funny, such as when Alexa hears its wake word in a TV show.Other times it’s more serious, including an instance in 2018 when Alexa mistakenly sent an entire private conversation to a random person’s Echo device. Occasionally there are even humans listening to your request for weather reports or trying to figure out what you meant when you added “mangosteens” to your shopping list. Sound disturbing? You likely already agreed to it in the app’s terms of use when you installed the device.
What bits of privacy are you willing to sacrifice for the convenience provided by a smart speaker? If you trust that Amazon’s intentions are no more immoral than getting a better idea of what you want to buy on Prime Day, then you have your answer. If you worry about your private information falling into the hands of the wrong people, then you have another answer.
