In the days before the Internet, critical thinking was the most important skill of informed citizens. But in the digital age, according to Anastasia Kozyreva, a psychologist at the Max Planck Institute for Human Development, and her colleagues, an even more important skill is critical ignoring. 

As the researchers point out, we live in an attention economy where content producers on the Internet compete for our attention. They attract us with a lot of emotional and eye-catching stories while providing little useful information, so they can expose us to profit-generating advertisements. Therefore, we are no longer customers but products, and each link we click is a sale of our time and attention. To protect ourselves from this, Kozyreva advocates learning the skill of critical ignoring, in which readers intentionally control their information environment to reduce exposure to false and low-quality information. 

According to Kozyreva, critical ignoring comprises three strategies. The first is to design our environments, which involves the removal of low-quality yet hard-to-resist information from around. Successful dieters need to keep unhealthy food out of their homes. Likewise, we need to set up a digital environment where attention-grabbing items are kept out of sight. As with dieting, if one tries to bank on willpower not to click eye-catching "news", he'll surely fail. So, it's better to just keep them out of sight to begin with.

The next is to evaluate the reliability of information, whose purpose is to protect you from false and misleading information. It can be realized by checking the source in the mainstream news agencies which have their reputations for being trustworthy. 

The last goes by the phrase "do not feed the trolls". Trolls are actors who intentionally spread false and hurtful information online to cause harm. It may be appealing to respond to them to set the facts straight, but trolls just care about annoying others rather than facts. So, it's best not to reward their bad behaviour with our attention.

By sharpening our critical ignoring skills in these ways, we can make the most of the Internet while avoiding falling victim to those who try to control our attention, time, and minds. 

Mosquitoes carry malaria (疟疾), which kills thousands of people each year. Now some researchers are trying to use genetic engineering to make the annoying insects into partners in the fight against the disease. 

For years, public health officials have tried to limit the disease by controlling mosquito populations. "But that approach is temporary, " says Anthony James, a professor of biology and genetics at the University of California, Irvine. "Because mosquitoes are extremely tough little insects, and their populations can quickly rebound. "

Therefore, James and his colleagues want to try a different approach: making mosquitoes themselves into malaria-fighting warriors, which is a complete departure from traditional ways of controlling malaria. 

To understand how it works, it helps to understand the life cycle of malaria. The malaria pathogen (病原体) is a parasite (寄生虫) that grows inside humans. It's passed via mosquitoes that move from person to person, sucking blood. "If we can make the mosquitoes difficult for the pathogens to survive, we can wipe out the disease, " he says. But making mosquitoes uninviting to malaria is a tough job.

To solve the problem, the team used a gene-editing technique called CRISPR. They started with genes from mice, whose immune systems do fight human malaria, engineered those genes, and then gave them to the mosquitoes. 

It turned out the malaria-fighting antibodies which gene-edited mosquitoes produced worked very well. They reduced the number of parasites in the mosquito before they were passed to a human host. 

James' team are now working on planning a field trial, which he hopes could be conducted on an island or in another isolated location.

But genetically changing wild animals does not sit well with environmentalists. "There's no need to engineer a mosquito, " says Dana Perls, senior program manager for the emerging technology program at the non-profit Friends of the Earth. Perls points out that naturally occurring methods for reducing malaria appear to be showing promise, as does a new vaccine (疫苗) against the disease. "Why take unnecessary risks and release a species that can't be recalled once it's released into the wild?" she asks.

Jose Alberto Gutierrez's life would never be the same again after finding a copy of Anna Karenina by Leo Tolstoy in the garbage 20 years ago. It happened while he was driving his garbage truck through wealthier neighborhoods at night and seeing deserted books. It sparked his desire to start rescuing books from the garbage. He took home 50 to 60 books every morning after his nine-hour shift. Eventually, he turned his book collection into a community library.

Colombia's capital city of Bogota has 13 million residents and 19 public libraries. However, these libraries tend to be far away from where rural and poorer communities live. The option of buying new books is non-existent for families struggling to make ends meet. Having access to a library of books and being taken away to another world while absorbed in a book is a luxury for the kids who visit Gutierrez's library.

Gutierrez grew up poor, and his family could not afford to educate him beyond primary school. Nevertheless, his mother was a keen reader and read stories to him every night. Her love for books left a deep impression on Gutierrez, who never let a lack of formal education stop him from reading classics by the likes of Victor Hugo, Mario Vargas Llosa and Gabriel Garcia Marquez. 

Today, his community library, called "The Strength of Words", occupies most of his home and is piled from floor to ceiling with fiction and non-fiction titles. Everything from school textbooks to story books can be found in his collection of more than 20, 000 books!

The Strength of Words library opens every weekend. It is not just school-going children who are enjoying the benefits of The Strength of Words library. Adults are also welcome to expand their horizons and develop new skills to build a better life for themselves. 

Despite having done so much for his community, Gutierrez is not yet content to call it a day. He continues to search through bins for reading material and has even travelled to book fairs in Mexico and Chile to sell his idea of building libraries from unwanted books.

Today, my family and I went hiking in the mountain where is rich in wildlife. We had a great time explored the beautiful scenery. We set out early in the morning, full equipped with snacks and water. During the climb, we watch the wildlife and took many photo. Besides, we have had a picnic lunch at the top of the mountain and enjoyed the peaceful surroundings. 

Personally, I felt a great sense of satisfaction after succeeding reaching the top. Though tiring, I considered them worth my time. Spending time with family in nature brought us much close to each other. 

The Hangzhou Asian Games served as not just a platform for Asian athletes(compete) in sports, but also a crucial stage to present the cultural (diverse) of Asian nations. 

"The Hangzhou Asian Games providedunique opportunity for people from 45 countries and regions to come together. " Yasuhiro Inomata said.

"This holds significant importance in promoting intercultural exchanges, as well as developing peace regionally and (globe), "Inomata added.

"The massive scale of this year's Asian Games not only reflects the development (achievement) in sports throughout Asia, but also ( symbolize) the unity of Asian people, " Raja Randhir Sing said, noting that the Hangzhou Asian Games presents a positive image of the mutual love and friendship (share) by Asian people.

" spectators, we felt that the message of unity and love was not just words but a feeling that reminded us that, despite our differences, we are all interconnected and(harmony) like one big family, " Kharaz, a reporter from Palestine, said.

"The Asian Games are an important platformdiverse traditions and cultures met, " Samir al-Musawi, head of the Iraqi delegation to Hangzhou, said to Xinhua.

In the post-war era, re-gifting and returning gifts to shops were commonly occurring. My mother and Aunt Florence ran a1 . For them finding desirable stock (储备物) for the store was an adventure. But the greatest2 of all was getting the wanted items without taking too many3 ones ‘paired' with them. This pairing resulted in a highly saleable item being paired with something that had to be heavily discounted just to move it off the shelves4 at a loss.

One item I particularly remember was an ugly ornament (饰物) framed in a horseshoe. My mother was shocked by its5  . My aunt patiently explained she had to buy it to6 some attractive crockery sets (瓷器套装) in high demand. She had paid ten pounds for it and hoped to get five pounds for it. After briefly7  it at ten pounds, she put it on our bargain table, expecting the crockery sets would sell quickly and cover the8  on it. Several days later she managed to sell the ornament for three pounds to a value d customer who 9 to give it to a neighbour, who loved horses. 

The following Saturday, our family was invited to a 21st birthday party, and my father was 10 with buying a suitable gift from the jeweler in town. However, he delayed his 11 because he had his car repaired. As a result, he 12 a wrapped present from our own store's stock. Little did he know that it was the 13 .

At the party, as the presents were14 , my mother held my shoulder tightly when she saw the ornament. The15 of our family, the gift's original purchaser, and the recipient's (接受者) family were a mix of shock and16 . My father, realizing his mistake, 17 that he thought it was a collector's item due to the ten pound price tag.

The next day, realizing my mother discovered the ornament which had been sold had been returned by Sheila, the recipient's mother, who 18 a ten pound refund , Aunt Florence burst into laughter, though the relationship between the19 owners of the ornament sourced.

 20  this event, I learned the value of giving cash or gift cards. 

To improve your confidence and set yourself up for sunnier times ahead, try these strategies:

Big yourself up. Rather than focusing on the negatives, make an effort to recognise your plus points. Make a list of the things you like about yourself and compliments people pay you. Give yourself a mini-makeover. Changing your appearance can have a significant impact on how you feel. It's amazing how good a new dress, a haircut, or having your teeth whitened can make you feel. Always stand tall just looking confident will help you feel more confident.

  Distance yourself from individuals who put you down. Research supports that supportive social relationships contribute to self-esteem. Make plans to spend time with these uplifting individuals and enjoy their company. 

Try something new. Stepping out of your comfort zone will give you a sense of achievement and help your self belief. It's the right season for this fun water sport! Would you like to paint better? Look around for an art class. You'll get to meet like-minded people too.

Spot your own talent. No? It's time to start! You might be surprised. It could be cooking cryptic crosswords, dancing, speaking a foreign language or repairing things. Doing more of the things that you do well and taking some time to improve will boost (增强) your self-confidence.

Honestly speaking, building self-esteem is a journey that takes time and effort. Be kind to yourself and practice these strategies consistently. 

A. Always fancied paddle boarding?

B. Make plans with positive people. 

C. Would you engage in outdoor exercise?

D. Refer to it when you're doubting your worth.

E. Spend time outdoors, preferably in green spaces. 

F. Do you ever think about your strengths and skills?

G. Even a humble shower can give your self-image a lift. 

Scientists have successfully recovered RNA, a form of genetic material, from the remains of the Tasmanian tiger, an extinct Australian animal. The discovery could help scientists learn more about these creatures before they disappeared from Earth. 

The researchers extracted the recovered RNA from the skin and muscle of a Tasmanian tiger specimen (标本) stored in a Swedish museum since 1891. This is the first time RNA has been successfully recovered from an extinct animal. The Tasmanian tiger was once a top predator, known for hunting kangaroos and other animals. The last known Tasmanian tiger is believed to have died in a Tasmanian zoo in 1936. Emilio Mármol Sánchez, from the Centre for Palaeogenetics, led the study describing these research results. Sánchez believes that the recovered RNA material provides a glimpse into the true biology of the Tasmanian tiger, offering insights into the cells and tissues of these extinct creatures. 

While Scientists have in recent years taken RNA from different ancient animals and plants, how long RNA could survive at room temperature has been a subject of debate among researchers. The well-preserved condition of the Tasmanian tiger remains, which were in a state of semi-mummification (半木乃伊化), suggests that RNA can survive for longer periods under certain conditions. 

The Tasmanian tiger looked similar to a wolf, except for the tiger-like lines appearing on its back. When people arrived in Australia about 50, 000 years ago, large animal population losses followed. The arrival of European colonizers in the 18th century destroyed the remaining populations around the island of Tasmania. 

Private "de-extinction" programs have been launched with the aim of bringing back some extinct animals. These include the Tasmanian tiger, flightless dodo bird and wooly mammoth.

However, many researchers have warned about the difficulties of using genetic processes to actually recreate an extinct species. While Sánchez said he too has concerns about such processes, he noted that he does "advocate for more research on the biology of these extinct animals. "

Bird expert James Zook has been collecting records on nearly 430 kinds of tropical birds on farms and natural forests in Central America for 18 years. While birds do best in natural rainforests, Zook said some species usually found in forests can establish populations in "diversified farms".

"In these diversified farms, you see growth over the long term in bird species with specialized needs, which include safe and protected areas from the sun for birds to build their homes and different kinds of food sources. Besides, that kind of farming is very different to industrial agriculture or agriculture where only one crop like pineapple or bananas are planted, " said Nicholas Hendershot in a recent study.

University of California environmental scientist Natalia Ocampo-Penuela, who was not involved in the study, notes that the research provides rare detailed data over a long period, demonstrating that diversified farming can support forest bird populations. 

The study reveals that 75 percent of the 305 bird species found in diversified farms showed stable or growing populations over the study period. This includes birds like the collared aracari and members of the manakin family known for their complex mating dances. 

Smithsonian Migratory Bird Center scientist Ruth Bennett, although not involved in the research, said, "It's a huge contribution to have documented that some birds aren't just going there, but staying there and populations are growing. "

Still, such safe environments, called habitats, do not balance out overall population losses from the creation of large industrial farms from natural forests, the writers warned. Zook compared a large pineapple farm to a "bird desert. "

Increasingly, scientists say saving species will require paying attention to areas affected by humans, not just untouched areas. Ocampo-Penuela says that conservation efforts should extend beyond protected areas to areas where some species can live. 

Now, Tenjen Sherpa, a Nepalese mountain guide, has set a new goal for himself; to become the youngest person to conquer all the peaks twice. 

Last month, together with Norwegian climber Kristin Harila, Tenjen, 35 years old, broke the previous record for the fastest climb of the 8, 000-meter-plus mountains. In just 92 days, they reached the final summit, K2, surpassing the previous record of 189 days. 

Tenjen is now preparing for his next challenge, starting with a climb of Mount Shishapangma in China within the next two months. He has already successfully climbed seven of the peaks twice and aims to conquer the remaining seven by next spring. 

His journey began in 2016 when he first climbed Mount Dhaulagiri in Nepal. Since then, he has made several similar climbs each year, including four trips to Mount Everest. Particularly, Tenjen and his three brothers also hold a record as the most siblings to summit Mount Kanchenjunga, the world's third-tallest mountain, behind Everest and K2.

Tenjen started working as a mountain guide to back his family. In April, he joined Harila's expedition to Mount Shıshapangma, hired by the Kathmandu-based company Seven Summits Treks. Together, they continued their journey, conquering the rest of the peaks.

Tenjen plans to climb Shishapangma for the second time in the upcoming fall carrying pictures of a deceased brother who never had the opportunity to conquer this mountain. He intends to bury these images at the mountaintop. 

Tenjen told Associated Press that Sherpas do not get enough government recognition for their hard work. "It is not possible to just continue climbing mountains as you grow older, so what else is there than to think of migrating abroad, " Tenjen pointed out.

Tenjen never attended school growing up. He has difficulty reading and writing. But, living in Kathmandu, Nepal's capital, his children are able to get an education. Tenjen thinks, though, that since more children will be growing up in cities in the future, they will not have the skills to become Sherpas.
