1 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie—all without other people hearing the sound. That is the possibility presented by “sound beaming,” a new technology from Noveto Systems, an Israeli company.
On Friday, the company presented a desktop device that sends sound directly to a listener without the need for headphones or a special receiver. Noveto Systems gave The Associated Press (AP) a chance to test its Sound Beamer 1.0 before its debut. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie. The sound seems so close it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D technology that finds and follows the ear position of the listener. It sends ultrasonic waves to create sound pockets by the user’s ears. Sound can be heard in stereo or 3-D. The 3-D method creates sound on all sides of the listener The demo version of the device included nature videos of birds on a lake, bees flying and a quiet waterway. By changing a setting, the sound can follow a listener around when they move their head. It also is possible to move out sound beam’s path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology. Its chief executive officer Christophe Ramstein said a smaller version of the device will be ready for release to consumers next year.

2 . These days there is so much tempting technology to look at: smart phones, tablets, computer games and TV screens. Much of children's entertainment and education comes from using them, so it's no wonder they spend so much time staring at them. But even if the saying that looking at a screen for too long gives you square eyes isn't true, there is still some concern. So, should we be worried?
Certainly for children who spend hours glued to a screen, there is a concern that their health might be at risk. Also there is a fear that their eyesight is declining too. Although there's not much evidence to prove this yet, recent findings have brought the problem into light.
Chris Hammond, consultant at St Thomas' Hospital, says “We find short-sightedness is becoming more common It has greatly spread in East Asia, Singapore, Taiwan, South Korea where approaching 90 of 18-year-olds are now short-sighted.”
But can this be linked to children's obsession with using electronic gadgets? Annegret Dahlmann, expert at Moorfields Eve Hospital in London. says lack of natural light seems to be the key issue. She's suggested that children in East Asia study a lot, using computers, smart phones or tablets, and they go outside less. Wearing glasses is one solution, but it's not ideal.
This leads to a dilemma: achieving short-term academic success or protecting your long-term eyesight. It's always going to be a challenge to drag children away from their screens and it's likely that more and more studying will be done online. But despite that, Professor Hammond says. “In countries like urban China, where 10% of children in each class per year are becoming short-sighted from about the age of six. there's an argument for saying we should be trying to prevent it.” It's evidence we can't turn a blind eye to. So, maybe it's time to hit the “off” button and get our children outside?

3 . The spot of red was what first caught Randy Heiss's attention on December 16. He was biking on his ranch in Patagonia, Arizona, a town near the U. S. -Mexico border. Heiss walked toward it, and found on the grassland was a broken balloon with its string attached to a piece of paper.
“Dayami,” it read on one side, in a child's writing. It was a Christmas wish list, all in Spanish He suspected that a child had tried to send Santa Claus a Christmas wish list by balloon, something he used to do himself when he was a kid. And he wondered whether he could find the child who had sent this one.
It would be difficult, but based on the prevailing wind, Heiss was pretty sure where it came from—just across the border, the city of Nogales, Mexico.
Heiss then posted about his quest on Facebook, attaching photos, hoping his friends in Nogales might know the girl's family.
A few days passed with no leads. Heiss worried that time was running out before Chirstmas. On December 19. he sent a private Facebook message to Radio XENY. a radio station based in Nogales The next morning. Heiss awoke to a message from Radio XENY: They had located Dayami, an eight-year-old girl, and her family, who indeed lived in Nogales. “It just changed my entire day.” said Heiss. Having bought just about everything on Dayami's list and a few other toys, as they had learned that Dayami had a younger sister, Heiss and his wife. at the Radio XENY. met the family.
“Their eves were wide open with wonder.” Heiss said of the two sisters' reactions. “Like. ‘Oh my gosh, this really did work!’”
Not wanting to disappoint the girls who still believed in Santa Claus, Heiss and his wife told them they were “Santa's helpers”.
“It was a beautiful and healing experience for us...” Heiss said, “Since our only son died ten years ago, being around children at Christmas time has been absent in our lives.” Heiss said. “We now have friends for life. And, for a day, that border fence with its wire melted away.”

4 . Perhaps thousands of people have searched for a bronze chest full of gold and jewels hidden in the Rocky Mountains between Santa Fe and the Canadian border hidden by a millionaire adventurer. At least four people died in their search for the treasure.
But it's all over now. Fenn's Treasure has been found. The 89-year-old adventurer named Forrest Fenn, who created the treasure hunt, announced the news via his website. “I don't know the person who found it, but the poem in my book led him to the precise spot,” Fenn wrote. “The treasure was confirmed by a photograph the lucky finder sent me.”
Forrest Fenn, the man who started the hunt, lives in Santa Fe. He was a pilot in the Vietnam War and later accumulated his wealth as a dealer in art and antiques. Fenn was diagnosed(诊断) with cancer in 1988 and had planned to die peacefully in the woods with his treasure. But when his cancer became less serious, he changed his plan, eventually writing the poem that described his dream resting place, which is where he hid the treasure. The poem appeared in a memoir called The Thrill of the Chase. Fenn said that the chest wouldn't be found by accident; only a treasure hunter who correctly interpreted the clues(线索) would find it.
Several treasure hunters went missing while attempting to find the chest, including hunter Jeff Murphy and Mike Petersen, both of whom went missing in Yellowstone National Park in 2017. Fenn said that he had never been to the Yellowstone National Park, and that the treasure was not in a dangerous place. "It was in the thick forest of the Rocky Mountains and had not been moved from the spot where I hid it more than 10 years ago," Fenn wrote on his website. It is illegal to remove anything from a national park, which would cause trouble in legally claiming the treasure if it was found there.

5 . Having worked for more than a decade in finance in the oil industry in Canada, Tori Fahey found herself wanting more from life. But it wasn't through desperation that her circumstances changed: “I didn't get fed up and storm off, nothing like that; it was curiosity about other interests and wanting to experience something new.”
Fahey left her job and completed an MBA before setting up a move to New York to begin a degree. However, the opportunity of an open year between the MBA and the degree came up, and as a keen touring cyclist, Fahey realised that a much dreamed-about adventure was now becoming a possibility: "The ride in Africa had been on my fantasy list. It was a moment when I realised that I could do anything, so I should."
Fahey rode across Africa, a 7,500-mile trip that took four months. The whole experience had a life-changing impact. Fahey said: “Bicycles provide a literal freedom. You don't allow yourself to feel like that in everyday life because there are so many distractions. But when you' re out on the bike and there's nothing else, you' re really free to experience what life is.”
Post-degree, Fahey worked on projects with the UNDP(United Nations Development Project) in Montenegro with the aim of bringing investment to rural communities.
It was while working on these projects that the seeds were sown for the next new investment. “It was through my trip across Africa that I discovered pannier and rack systems inconvenient and I was never going to use them again.” Little did she know this would lead her to start up her own company.
In 2013, Apidura was born, producing storage solutions for people looking to travel the world by bike, race across continents and carry all they need to do so. It's now a successful global brand, but Fahey remains reflective about what else the company can do for people.

6 . Ever wonder how your brain works when making decisions bigger than medium versus spicy salsa, like buying a car or accepting a job offer? Researchers from the University of Dundee in Scotland conducted a study that clarifies why you may want to have a small bite before making that big decision.
Benjamin Vincent from the University of Dundee’s Psychology department and his co-author Jordan Skyrnka tested 50 people two times: once when they followed their normal eating patterns and once when they did not eat anything during the day. Using three different types of rewards (food, money, and song downloads), the team discovered when presented with the choice of receiving the reward now versus double the award at some point in the future, participants would usually volunteer to wait for 35 days to earn a larger bounty, but when they were hungry, they said they would only wait three days.
“We wanted to know whether being in a state of hunger had a specific effect on how you make decisions only relating to food or if it had broader effects, and this research suggests decision-making gets more present-focused when people are hungry,” Vincent said in a story about the study on the university’s website. “You would predict that hunger would impact people’s preferences relating to food, but it is not yet clear why people get more present-focused for completely unrelated rewards. Hunger is so common that it is important to understand the non-obvious ways in which our preferences and decisions may be affected by it,” he said.
In an earlier study of the subject by a team at Cambridge University in England, the researchers noted that serotonin plays a major role in the decision-making process. “Since the raw material for making serotonin—an amino acid called tryptophan — only comes from diet, levels of the chemical decline between meals,” reports a piece in the Telegraph about the study. “This can lead to aggressiveness and impulsiveness,” say the team.

7 . Kleon Papadimitriou, a Greek student, had been stuck in Scotland, where he studies, with no way to return to Athens while flights were shut down. So he decided to take a bike.
He began researching what it would take to make the trip on two wheels. He once competed in a race in 2019 and was briefly trained for several weeks — but that was about all the biking experience he carried with him.
Initially, he thought the idea was more of a “dream”— an absolutely hard long journey. But soon he began purchasing the equipment he'd need. He purchased a bike, and told the news to his parents and friends.
Papadimiriou travelled anywhere between 35 and 75 miles per day, crossing initially through England and then onto the Netherlands. He biked along the Rhine in Germany for several days, passed through Austria and cycled down along the eastern coast of Italy before he took a boat to the Greek port of Patras.
Throughout his trip, he set up camp in fields and forests. He spent the last few moments of each day writing down his progress, tracking the next day's path and checking in with family and friends.
“It's just now dawning on me how big of an achievement this was.” Papadimitriou says of his 48-day journey. “And I did learn a lot of things about myself, about my limits, my strengths and my weaknesses. I really hope that the trip can inspire at least one more person to go out of their comfort zone and try something new, something big.”
1. What can we infer about Kleon Papadimitriou?| A．He was forced to leave for Scotland on bike. | B．He had a few biking experience before. |

8 . Reducing plastic waste isn't easy because the cheap material is found in almost every household item. Now, a delicious and nutritious solution has come up to help reduce our dependence on this environmental hazard.
David Christian, the co-founder of Evoware, says the idea of creating the biodegradable (生物降解的) products came from concern at the country’s high pollution rate. Indonesia is home to four of the world's worst polluted rivers. Since single-use packaging is a large contributor to the problem, Evoware decided to deal with that first.
After investigating various materials, the company settled on seaweed. Unlike corn, commonly used for biodegradable containers, seaweed does not require resources like water or large amounts of space. Since Indonesian farmers already harvest more seaweed than they can sell, it's easy for the company to find the material.
Though they will not reveal their production process, Evoware says the seaweed packaging contains no chemicals and is safe to consume. The company has also invented single-use cups, which can break down 30 days after they're thrown away.
While replacing plastic with the seaweed products may seem appealing to most of us, it is a hard-sell in Indonesia. According to Christian, ''The awareness to reduce single-use plastic is still very low. This makes our bioplastic unnecessary.” Also a factor is the cost, which is higher than using plastic. Hopefully, Evoware will succeed in convincing Indonesians and people worldwide that switching to their products will be helpful to protecting our beautiful planet.

9 . We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell, a team of researchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of sea-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as these people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houseboats; in recent times, they’ve also built houses on stilts (支柱) in coastal waters. “They are simply a stranger to the land,” said Redney C. Jubilado, a University of Hawaii researcher who studies the Bajau.
Dr. Jubilado first met the Bajau while growing up on Samal Island in the Philippines. They made a living as divers, spearfishing or harvesting shellfish. “We were so amazed that they could stay underwater much longer than us local islanders,” Dr. Jubilado said. “I could see them actually walking under the sea.”
In2015, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it seemed like the perfect chance for natural selection to act on a population,” said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.

10 . Life satisfaction is the way persons evaluate their lives and how they feel about their directions and options for the future. It's a measure of well-being and may be evaluated in terms of mood, satisfaction with relations with others and with achieved goals and self-concepts to cope with daily life. It's having a favorable attitude towards one's life as a whole rather than just an evaluation of current feelings. Life satisfaction has been measured in relation to economy, education, experiences, and residence, as well as many other topics.
Life satisfaction can reflect experiences that have influenced a person in, a positive way. These experiences have the ability to motivate people to pursue and reach their goals. As a matter of fact, in these experiences there are two kinds of emotions that may positively influence how people understand their life. Hope and optimism both consist of emotional processes that are usually directed towards the reaching of goals. People who have higher life satisfaction are always full of hope for a better future; additionally, optimism is linked to higher life satisfaction, while pessimism is related to symptoms in depression.
The psychologist, Yuval Palgi, studied the old-old-people who were primarily in their nineties. This subject group was found to have thought highly of their past and present, but they thought lower of their future. A large factor that was talked about in life satisfaction was intelligence. The experiments talk of how life satisfaction grows as people become older because they become wiser and more knowledgeable, so they begin to see that life will be better as they grow older and understand the important things in life more. But when they step into their nineties, future becomes a luxury to them.
According to Seligman, the happier people are, the less they are focused on the negative. Happier people also have a greater tendency to like other people, which promotes a happier environment, which then correlates to a higher level of the persons' satisfaction with their life.
