Off the coast of Hawaii's Big Island swim masses of colorful tropical fish. Some of these fish will be caught and sold, ending up in aquariums around the world. Is the industry putting populations of the fish at risk?

    Scientists who have studied the Big Island fishery say it is well managed. Rules put in place more than 15 years ago have helped to protect the fish. Along 35% of the coastline, for example, fish collecting is banned. Two years ago, the state cut the number of fish species for the aquarium trade from hundreds to just 40.

    Conservationist Robert Wintner objects to the findings. Wintner, who owns snorkel shops across Hawaii, started the Snorkel Bob Foundation to protect the island's coral reefs(珊瑚礁). He says he simply doesn't see yellow tang(刺尾鱼)in the protected areas. “There should be millions of them,” he says. “Where are they?”

    Wintner says people believe the numbers in reports. But few people have actually dived into the coral reefs to see for themselves how many fish can be found there. According to Wintner, the coral reefs along the coast should be filled with yellow tang, but they are “virtually empty”. Empty reefs are not good for tourism, Wintner points out, which brings out $800 million yearly. By contrast, the aquarium-fish trade brings out just $2 million yearly.

    I live in the center of the city and there is a largeparking lot full of parking spots nearby. Rain is a rare occurrence in LA,so cars easilycollect pollutants and dust. Together with my friends,I decided it shouldbe a kind gesture to surprise the owners with a car wash.So we bought carwashing supplies and brought out all the bath towels we could find.With all the suppliesin hand, wewere able to convince another roommate to help out as well and we beganwatering down the cars.

    Every once in a while, someone would come by and asked usseemingly stupid men, "Who told you to wash the cars?" or, even better, "who paid you to wash their cars?" Weexplained we just wanted to do something kind. But our response was often me with aneven more confused look.

    As the afternoon went on, some other friends that came byunderstood our goal of the spontaneous event and started helping out with someof the duties. Firstone friend then two, and by the time we had cleaned the entire lot,we had an entire carwashing crew with independent individually assigned tasks and duties.

    I wasn't cleaning cars to be able to afford a new phone.I was cleaning carssimply because I wanted to offer the car owners kindness.There was noequipment to weigh our value created. We couldn't measure our success indollars earned over the time spent washing cars when we could have been earningtwice as much at work.

    I now realize, first hand, that there is a special energy createdwhen you choose to think bigger than yourself and act in service of others andmaybe, likeme, you'llfind it's actually the greatest gift you' you'll ever get.

    An “adulting conference” (AC)this week allowed Kentucky high school seniors the chance to learn how to change a tire, how to cook and other basic life skills—things that they may not have learned at home or in classes. A series of photos posted by Bullitt Central High School on social media shows students taking “adulting conference” are learning about personal finances, resumes and other essential skills at the event, which has been widely reported on the local and national news outlets.

    “I saw a Facebook post that parents passed around saying they needed a class in high school on taxes and cooking,” AC organizer Hardin told Louisville's WAVE 3 News. Those skills are taught at school theoretically, she said, but the event gave students a chance to fill in gaps in their knowledge.

    Students could choose to attend three workshops out of 11 total options, the school says. The workshops were held in cooperation with numerous community partners.

    Some young people have left home and graduated school without having those gaps filled, according to a report this week from CBS New York, which documented a trend of young people seeking outclasses to learn basic life skills.

    While attending a cooking class, 29-year-old Elena Toumaras told the station she's struggling with “simple things.”

    “I was so used to, when living at home, my mom always cooking,” she told the station.

    An“Adulting School” in Portland, Maine, aims to use a new online format to teach the youths skills like conflict resolution, sewing and appreciation for all, the station says.

    Students' financial literacy has been of particular concern to some experts, as financial education in schools has stagnated(停滞)in the U.S., with only 17 states requiring students to take classes in personal finance—a number that hasn't risen in years.

    “The majority of U.S. states are failing our students by declining to offer these fundamental courses which are critical to their financial stability and security later in life. And this will be changed.” Nan J. Morrison, president and CEO of the Council for Economic Education, told CNBC.

    Donna Strickland is a professor in the Department of Physics and Astronomy. Professor Strickland is one of the recipients( 受领者) of the Nobel Prize in Physics 2018 with Gérard Mourou, her PhD supervisor at the time. They published this Nobel-winning research in 1985 when Strickland was a PhD student at the University of Rochester in New York state. Together they paved the way toward the most intense laser pulses ever created.

    Professor Donna Strickland is only the third woman ever to have won a Nobel Prize in physics. She and her fellow winners were honored for what the Nobel Committee called ground-breaking inventions in laser physics. Professor Strickland devised a way to use lasers as very precise drilling or cutting tools. Millions of eye operations are performed every year with these sharpest of laser beams.

—"How surprising do you think it is that you're the third woman to win this prize? "

—"Well, that is surprising, isn't it? I think that's the story of Maria that people want to talk about — that why should it take 60 years? There are so many women out there doing fantastic research, so why does it take so long to get recognized? "

    Physics still has one of the largest gender gaps in science. One recent study concluded that at the current rates it would be more than two centuries until there were equal numbers of senior male and female researchers in the field.

    The last woman to win a physics Nobel was German-born Maria Goeppert-Mayer for her discoveries about the nuclei of atoms. Before that it was Marie Curie, who shared the 1903 prize with her husband, Pierre. This year's winners hope that breaking this half century hiatus will mean the focus in future will be on the research, rather than the gender of the researcher.

    Students perform less well in final exams if smartphones are allowed in class, for non-academic (非学业的) purposes in lectures, a new study in Educational Psychology finds. Students who don't use smartphones themselves but attend lectures where their use is acceptable also do worse, suggesting that smartphone use damages the group learning environment.

    Researchers from Rutgers University in the US performed an in-class experiment to lest whether dividing attention between smartphones and the lecturer during the class affected students' performance in within-lecture tests and a final exam. 118 students at Rutgers University took part in the experiment during one term of their course. Smartphones were not allowed in half of the lectures and allowed in the other half. When smartphones were allowed, students were asked to record whether they had used them for non-academic purposes during the lecture.

    The study found that having a smartphone didn't lower students' scores in comprehension tests within lectures, but it did lower scores in the final exam by at least 5%, or half a grade. This finding shows for the first time that the main effect of divided attention in the classroom is on the length of time in keeping memory, with fewer things of a study task later remembered. In addition, when the use of smartphones was allowed in class, performance was also poorer for students who did not use them as well as for those who did.

    The study's lead author, Professor Arnold Glass, added: "These findings should alarm students and teachers that dividing attention is having a not obvious but harmful effect that is damaging their exam performance and final grade. To help manage the use of smartphones in the classroom, teachers should explain to students the alarming effect—not only for themselves, but for the whole class."

    This is the first-ever study in an actual classroom showing a relationship between losing attention from smartphones and exam performance. However, more researches are required to see how students are affected by using smartphones after school.

    Sweetest Day is always the third Saturday in October. This holiday is much more important in some regions than in others (Detroit, Cleveland and Buffalo being the biggest Sweetest Day cities). It is a holiday that is gaining in popularity every year throughout the country.

    Sweetest Day is celebrated on the third Saturday in October as a day to make someone happy. It is an occasion which offers all of us an opportunity to remember not only the sick, aged, and orphaned, but also friends, relatives and associates whose helpfulness and kindness we have enjoyed.

    Over 60 years ago, a Cleveland man, believing that the city's orphans and shut-ins (卧病在床的人) too often felt forgotten and neglected, formed the idea of showing them that they were remembered. He did this through the distribution(分发) of small gifts. With the help of his friends and neighbors, he distributed these small remembrances on a Saturday in October. During the years that followed, other Clevelanders began to participate in the celebration ceremony, which came to be called "Sweetest Day". In time, the Sweetest Day idea of spreading cheer to the underprivileged(弱势群体)was broadened to include everyone, and became an occasion for remembering others with a kind act or a small remembrance. And soon the idea spread to other cities all over the country.

    Sweetest Day is not based on any single group's religious belief or on a family relationship. It is a reminder that a thoughtful word or deed enriches life and gives it meaning. Because for many people remembering takes the form of gift-giving, Sweetest Day offers us the opportunity to show others that we care, in a practical way.
