Mya Le Thai is a scientist studying at the University of California, Irvine. She recently discovered a process that may result in batteries that last forever. Thai said she had been discouraged that the batteries for her wireless devices degrade. Over time, they fail to charge fully.

    Thai did not like to have keep her wireless laptop connected to an electrical outlet. She decided to do something about that problem.

    At first, she and her team thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子) batteries to last forever. Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a charge. Most of these batteries have a life span of about 7,000 charging cycles before they die.

    One of the reasons lithium-ion batteries degrade is their use of nanowires(纳米线) to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extremely efficient carriers of electricity, which makes them useful in batteries. But Thai said their thinness also makes them weak. "Nanowires break over time," she said. "That's why they lose capacity."

    But, Thai had a theory: The nanowires might last longer if covered with a material. She and the team tested her theory. The team tried many coverings for the wires. PMMA was one of them. The nanowires were coated with PMMA and cycled through charges 200,000 times. The PMMA coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability.

    Thai hopes to continue her research to understand why this material works so well and to see if any other material could create better results.

"It's kind of cool," she said. "I'm really glad people are showing interest in my work and not just in the work itself, but also in technology and energy."

    We walked in so quietly that the nurse at the desk didn't even lift her eyes from the book. Mum pointed at a big chair by the door and I knew she wanted me to sit down. While I watched mouth open is surprise, Mum took off her hat and coat and gave them to me to hold. She walked quietly to the small room by the lift and took out a wet mop. She pushed the mop past the desk and as the nurse looked up, Mum nodded and said, "Very dirty floors. "

    "Yes, I'm glad they've finally decided to clean them, "the nurse answered. She looked at Mum strangely and said, "But aren't you working late?"

    Mum just pushed harder, each swipe(拖一下)of the mop taking her farther and farther down the hall. I watched until she was out of sight and the nurse had turned back to writing in the big book.

    After a long time Mum came back. Her eyes were shining. She quickly put the mop back and took my hand. As we turned to go out of the door, Mum bowed politely to the nurse and said, "Thank you."

    Outside, Mum told me, "Dagmar is fine. No fever. "

    "You saw her, Mum?"

    "Of course. I told her about the hospital rules, and she will not expect us until tomorrow. Dad will stop worrying as well. It's a fine hospital. But such floors! A mop is no good. You need a brush."

    An introduction to this book is as superfluous as a candle in front of a powerful searchlight. But a convention of publishing seems to require that the candle should be there, and I am proud to be the one to hold it. About ten years ago I picked up from the pile of new books on my desk a copy of Sons and Lovers by a man of whom I had never heard, and I started to race through it with the immoral speed of the professional reviewer. But after a page or two I found myself reading, really reading. Here was—here is—a masterpiece in which every sentence counts, a book packed with significant thought and beautiful, arresting phrases, the work of a remarkable genius whose gifts are more richly various than those of any other young English novelist.

    To appreciate the rich variety of Mr. Lawrence we must read his later novels and his volumes of poetry. But Sons and Lovers reveals the range of his power. Here are combined and blended(混合的) sort of “realism” and almost lyric(抒情的) imagery and rhythm. The speech of the people is that of daily life and the things that happen to them are normal adventures and accidents; they fall in love, marry, work, fail, succeed, and die. But of their deeper emotions and of the relations of these little human beings to the earth and to the stars, Mr. Lawrence makes something near to poetry and prose(散文) without violating its proper “other harmony.”

    Take the marvellous paragraph on next to the last page of Sons and Lovers (Mr. Lawrence depends so little on plot in the ordinary sense of the word that it is perfectly fair to read the end of his book first):

    Where was he? One tiny upright speck of flesh, less than an ear of wheat lost in the field. He could not bear it. On every side the immense dark silence seemed pressing him, so tiny a spark, into extinction, and yet, almost nothing, he could not be extinct. Night, in which everything was lost, went reaching out, beyond stars and sun, stars and sun, a few bright grains, went spinning round for terror, and holding each other in embrace, there in the darkness that outpassed them all, and left them tiny and daunted(气馁). So much, and himself, infinitesimal, at the core a nothingness, and yet not nothing.

    Such glorious writing lifts the book far above a novel which is merely a story. I beg the reader to attend to every line of it and not to miss a single one of the many sentences that await and surprise you. Some are enthusiastic and impressive, like the paragraph above; others are keen, “realistic” observations of things and people. In one of his books Mr. Lawrence makes a character say, or think, that life is “mixed.” That indicates his philosophy and his method. He blends the accurately literal and trivial(琐碎的) with the extremely poetic.

    To find a similar blending of tiny daily detail and wide imaginative vision, we must go back to two older novelists, Hardy and Meredith. I do not mean that Mr. Lawrence derives(源于) immediately from them or, indeed, that he is clearly the disciple(弟子) of any master. I do feel simply that he is of the elder stature(名望) of Hardy and Meredith, and I know of no other young novelist who is quite worthy of their company. When I first tried to express this comparison, this connection, I was contradicted by a fellow-critic, who pointed out that Meredith and Hardy are entirely unlike each other and that therefore Mr. Lawrence cannot resemble both. To be sure, nothing is more hateful than forced comparisons, nothing more boring than to discover parallels between one work of art and another. An artist's mastery consists in his difference from other masters. But to refer a young man of genius to an older one, at the same time pronouncing his independence and originality, is a fair, if not very superior, method of praising him.

    Full House was an American television show from the 1980s to the 1990s. It was among the most popular TV shows of its time. The show followed a single father who asks his friends to help him raise his three young girls. The last episode (集）of Full House aired in May 1995.

    But on Friday, the No 1 trending topic on Twitter in the U.S. was Fuller House. The new show is the long-awaited sequel (续集）series that follows the now-adult characters from Full House. The streaming service Netflix released 13 episodes of the new series at midnight Friday.

    Fuller House trended throughout the night and into Friday morning on Twitter and Facebook. The actors on the show were among :he :op 10 U.S. Google searches, as well Longtime fans of Full House admitted that they stayed up all night to watch the entire season.

    Excited fans tweeted about having waited more than 20 years for the sequel. But some viewers were not impressed with Fuller House. And television critic Hank Steuver of The Washington Post called the show, “a retread' He says the show is not some golden treasure* of family-friendly programming.

    Although most of the main characters from the original Full House have returned for Fuller House, the show's youngest character, Michelle Tanner, refused. Michelle was played by twins Mary-Kate and Ashley Olsen. The Olsens are now active in the fashion world. One episode of Fuller House even joked about their absence. One of her sisters on the show asks where Michelle is. Her father, Danny Tanner, responds: “Oh, she's busy in New York running her fashion empire.”

    The human-caused rise in CO₂ hasn't yet reached its full warming effect, owing to the considerable delay in its impact on ocean temperature. There is still another 0.5^oC of so of warming to occur over the coming decades based on the current concentrations（浓度）of CO₂ in the atmosphere, and far more warming beyond that if CO₂ concentrations continue to rise greatly with the business-as-usual burning of fossil oil. To improve the situation, the world needs to shift firmly from coal, oil and gas to renewable energy by around 2050 and from cutting down trees to planting trees and restoring degraded lands.

    So why do human begins keep dashing in a stupid way ahead, toward certain tragedy?

    The main reason is that our political institutions and giant corporations intentionally ignore the rising dangers and damage.   ①    Managing a major company is about maximizing shareholder value, not about telling the truth or avoiding great harm to the planet. Profit -seeking investors own the major media, or at least influence them through their advertising purchases. Thus, a small yet very powerful group keeps the fossil-fuel-based energy system at growing dangers to the rest of humanity today and in the future.

    We need a new kind of politics that starts with a clear goal: environmental safety for the planet's people, by fulfilling the Paris agreement, protecting biodiversity, and cutting pollution, which kills millions each years.   ②    The new politics will listen to scientific and technological experts, not self-interested business leaders and politicians.

       ③    Such a politics is possible. In fact, the public longs for it. A large majority of the American people,for example, want to fight global warming, stay in the Paris climate agreement, and support renewable（可更新的）energy. Yet, as long as a narrow and ignorant elite（精英）judges Americans and the rest of human beings to wander aimlessly in the political desert, the more likely it is that we will end up in a wasteland from which there will be no escape.  ④   

15 years ago, Erin Merryn met a kitten who needed a home when she was a college student.

He jumped into her arms and refused to let her go.

"I was attached immediately and decided that I would take a risk and try hiding a kitten in my college dorm where animals are obviously not allowed," Erin recalled.

A week later she was caught and given 48 hours to remove the cat. After several phone calls, Erin was able to find an old lady to take Bailey, the kitten. But Bailey did not get along with his new housemate. As soon as Erin learned that he would be sent away, she immediately offered to take him back. "I plotted for a month to convince my parents to let me keep him." said Erin.

Six years ago, Erin had Abby, her beautiful daughter. She didn't know what Bailey would think about the new addition when she brought her home from the hospital.

"But it was love at first sight." Erin said. Bailey stayed by Abby's side, guarding and showering her with love and purrs. As Abby grew, he became her protective brother, watching over her every step of the way. Abby picked up a book one day and tried to read it with Bailey by her side. He became her perfect audience, and the sweet boy was completely attracted by Abby as she told him stories of wonder.

A video showing Abby reading to Bailey went viral on the Internet in 2018. Numerous people followed Erin on social media platforms.

Unfortunately, on December 8, 2018, just months after becoming famous, the 14-year old cat passed away from kidney failure.

A full month after Bailey's passing, Erin still got cards and gifts from caring individuals. It is this love that Erin hopes Bailey's fans hold on to. She wants her furry "first-born" to be remembered as a symbol of compassion that inspires others to treat the world with love.
