    Researchers in China and the United States have developed a new cataract(白内障)treatment with cells that has restored vision in babies in a trial and may eventually be used in adults.

    The treatment- by doctors and staff members at the University of California, San Diego School of Medicine and Sichuan and Sun Yat-sen universities in China-was published in March 9 edition of the scientific journal Nature.

    A cataract is a clouding of the normally clear lens(晶体)of an eye. Typical cataract operation involves the removal of the cloudy lens and the insertion of an artificial one. The new operation has been tested in animals and during a small, human trial. It resulted in fewer complications(并发症)than the current harmful operation, and in regrown lenses with superior visual function in all 12 of the baby cataract patients who received the procedure.

    A congenital cataract- lens clouding that occurs at birth or shortly after- is important cause of blindness in children. In the new research, Kand Zhang, head of ophthalmic genetics at US San Diego's Shiley Eye Institute, and his colleagues relied on the regrown potential of endogenous(同源的)stem cells.

    According to Zhang, endogenous stem cells are different from other stem cells that are typically grown in a laboratory, transplanted into a patient, and can have risks of immune(免疫的)rejection, infection or cancers. Zhang told CBS News, “We invented a new operation to make a very small opening at the side of a cataractous lens bag, remove the cataract inside, allow the opening to heal, and promote potential lens stem cells to regrow an entirely new lens with vision.”

    The human trial involved 12 babies under the age of 2 who were treated with the new method, while 25 babies received thee standard operation care.. The latter group experienced a higher incidence of pos- operation danger, early- onset eye high blood pressure and increased lens clouding. The scientists reported fewer complications and faster healing among the 12 babies who has the new procedure.

    What's the biggest online shopping day in the world? Not Valentine's Day. Not Cyber Monday or Black Friday. The winner is China's Singles' Day, celebrated on November11, or 11.11.

    Singles' Day began as a day for unmarried or uncoupled people to celebrate their lives. Single students, looking for an excuse to buy themselves presents, started it on November11,1993, reported The Guardian. It is symbolized by the four mumber ones in the date of November11 and is also called Double Eleven, in reference to the day it was started, said the BBC. It became a major shopping day in 2009. The CEO of an online shopping site --Alibaba-- tried to increase sales at the e-commerce company. The CEO, Daniel Zhang, launched an annual online sale on that day, said Fortune. When it first began, "Sigles' Day was very much an offline comfort to actual single people," noted the website atlas Obscura."A small group of students at Nanjing University are said to have chosen 11.11 as a day that singles could do activities like karaoke together." It quickly became a cultural phenomenon.

    Last year, Alibaba sold more than $1 billion worth of products in the first three minutes of the sales, reported Bloomberg News. Total sales on Singles' Day soared to $9 billion within 24 hours. That's four times bigger than Cyber Monday in the U.S., which is the Monday after Thanksgiving and traditionally a big shopping day. By comparison, online sales in the U.S. last year on Black Friday were just $1.5 billion, reported TechCrunch.

    Today, Singles' Day is very successful. Analysts say that this year, sales on China's Singles' Day will increase to a new high. In the U.S., Jennifer Wang, a co-founder of a company targeting Chinese-Americans, said, "We expect to have 3 million people coming to click Dealmoon for the Singles' Day launch." Some observers think Singles' Day could catch on globally.

    The burst of barking suddenly woke me up. It was 2:30 a.m. in the early morning. Wondering why Rock was making so loud noises, I decided to go to him. By the time I made it to the bottom of the stairs, he was running up. I felt strange, for he had never come up the stairs, no matter what. I think that was his way of telling me, “We've got to go back up.”

    When I got to the top of the stairs, I turned around and saw a light on, but I didn't remember leaving one on. I walked downstairs again, and that's when I saw fire. I immediately shouted to my wife to wake up and get our three kids. I grabbed a knife and cut out the plastic that covered the window to the porch roof. I then forced open the window and kicked out the screen. I got everybody out on the roof and threw a blanket out there so we wouldn't slip off. It was cold, January cold. Then I started screaming for help. But help never came.

    I was scared of heights, but I couldn't let my family burn up. So I just jumped off the roof and got the wind knocked out of me when I landed.

    I found our ladder, placed it against the house, and climbed back up to the roof. I wrapped my arms around my daughter and carried my nine-month-old with my teeth, by his little sleeper. Then I climbed down the ladder. Once on the ground, I had my little girl hold her brother, and I went back up to the roof to get my other daughter. Then I went back up again and got my wife. I tried to get my dog, but he just disappeared in the black smoke. I never saw Rock alive again.

    I have been unusually silent these past ten months. I had thought that silence would soon be coming to an end,, but I'm afraid I must tell you now that fate(命运)has decided on a different course for me.

    In August of last year, I underwent surgery to remove a cancerous tumor in my abdomen. That operation was thought to have been a success, but it caused a series of secondary complications – which I have been fighting in hospital ever since. It was along and hard fight with many setbacks, but I was steadily, if slowly, overcoming each obstacle along the way and gradually making my way back to health.

    However, recent tests have revealed that the cancer has returned. There was no sign or it as recently as a month ago, which means it is aggressive and spreading rapidly. My doctors tell me their best estimate is that I have only a few weeks left to live. This is the final conclusion. My fight is over.

    I wish to thank my doctors and caregivers, who efforts have been magnificent. My dear friends, who have given me a lifetime of memories and whose support has sustained me through these difficult months. And all of my partners at The Washington Post, Fox News, and Crown Publishing.

    Lastly, I thank my colleagues, my readers, and my viewers, who have made my career possible and given consequence to my life's work. I believe that the pursuit of truth and right ideas through honest debate and thorough argument is a noble undertaking. I am grateful to have played a small role in the conversations that have helped guide this extraordinary nation's destiny.

    I leave this life with no regret. It was a wonderful life – full and complete with the great loves and great endeavors that make it worth living. I am sad to leave, but I leave with the knowledge that I lived the life that I intended.

    Apple announced its new iPhones last week, but competitors' mobile phones can do many of the same things for less money.

    The new iPhone 8 and X have wireless charging, edge-to-edge glass screen and double cameras. But all of these features are already available in smart phones from China's Huawei and Oppo, and Korea's Samsung. While Apple asks buyers to pay $1,000 for its high-end model, some Asian phone makers can offer similar features for less.

    At one time, Chinese manufacturers copied features and designs from others to produce low-cost phones. But they have now added high-end features to their phones and they control nearly half the global mobile phone market.

    Media MarktSaturn is Europe's biggest electronics seller. A spokesperson for the store told Reuters that,“Huawei is seen as a relevant competitor to Apple and Samsung by covering all major price points and placing big investments in marketing and sales. '' She also said that the Chinese companies Huawei, ZTE, Lenovo and TCL were among the top-10 best-selling smart phones in its stores.

    Chinese manufacturers' fast growth has been fueled by strong sales in China. But they now export 40 percent of their smart phones. That is almost double the number from just three years ago, according to the Hong Kong investment company CLSA.

    Huawei is currently the world's third largest phone maker behind Samsung and Apple. According to research company Canalys, the Chinese company is getting closer to second-place Apple and might overtake it later this year.The Chinese company even made fun of Apple's new facial recognition feature with a Facebook video called "Real AI phone." Huawei plans to show its top-of-the-line Mate 10 phone on Oct. 16. The phone will have artificial intelligence features such as instant translation and image recognition and will cost less than $1,000.    Other Chinese companies are looking to enter the high-end smart phone market.

    A monk lived with his brother, a one-eyed idiot(a very stupid person).One day ,when the monk was scheduled to have an interview with a famous theologian(a scientist who studies religions) who had come from far away to meet him, he needed to take care of some matters and would therefore be absent when the theologian arrived. He told his brother: "Receive this scholar and treat him well!Don't say a word to him,and everything will be OK."

    The monk left the temple. Upon returning, he went to meet his guest.

    "Did my brother receive you properly?" asked the monk.

    "You brother is outstanding. He's a great theologian!" exclaimed the theologian with great enthusiasm.

"What do you mean? My brother—a theologian?" stuttered(结巴地说)the surprised monk.

    "We had a passionate conversation," replied the scholar." We communicated professionally by means of gestures. I showed him one finger and he replied by showing me two. Logically, I answered with three fingers and then he astonished me by raising a closed fist, ending the debate. With one finger, I implied the unity of Buddha. With two fingers, he expanded my point of view by reminding me that Buddha was inseparable from his theory. Delighted by the reply, with three fingers I expressed: Buddha and his theory in the world. Then he suggested a wonderful response, showing me his fist: Buddha, his theory and the world, all together as one whole. "

    A little later, the monk went to look for his one-eyed brother.

    "So how did it go earlier with the theologian?" he asked.

    "Very simple," said the brother. "He made fun of me; he show me one finger emphasizing that I have but one eye. Not wanting to fall into the conflict, I showed that he was fortunate enough to have two eyes. Critically, he continued, 'Be that as it may, between us, we have three eyes.' That was the straw that broke the camel's back. Showing him a closed fist, I threatened to lay him out right then and there if he didn't stop his insulting challenges."

    Last week, Vodafone started a test of the UK's first full 5G service, available for use by businesses in Salford. It is part of its plan to trial the technology in seven UK cities. But what can we expect from the next generation of mobile technology?

    One thing we will see in the preparation for the test is lots of tricks with the new tech. Earlier this year, operators paid almost £ 1.4 billion for the 5G wavelengths, and to compensate for that cash, they will need to catch the eye of consumers. In September, Vodafone used its bit of the range to display the UK's first hologram (全息) call. The Manchester City captain Steph Houghton appeared as a hologram in Newbury. It isn't all holograms, however: 5G will offer faster internet access, with Ofcom (英国通讯管理局) suggesting that video that takes a minute to download on 4G will be available in just a second.

    The wider application is to support connected equipment on the "internet of things" -not just the internet-enabled fridge that can reorder your milk for you, but the network that will enable driverless cars and delivery drones (无人机) to communicate with each other.

    Prof William Webb has warned that the technology could be a case of the emperor's new clothes. Much of the speed increase, he claims, could have been achieved by putting more money in the 4G network, rather than a new technology. Other different voices have suggested that a focus on rolling out wider rural broadband access and addressing current network coverage would be more beneficial to the UK as a whole.

    Obviously, 5G will also bring a cost to consumers. It requires a handset for both 5G and 4G, and the first 5G-enabled smart phones are expected in the coming year. With the slow pace of network rollout so far, it is likely that consumers will end up upgrading to a new 5 G phone well before 5 G becomes widely available in the next couple of years.
