1 . E-cigarettes Ban:Good news for Tobacco?
The proposed ban on flavored e-cigarettes may drive many Americans back to cigarettes,said Christopher Palmeri and Jeff Green in the Los Ange Times.
Responding to an outbreak of hundreds of serious lung illnesses from vapes(电子烟)that killed a seventh person this week, FDA(食物药品监管局)will outlaw everything but tobacco-flavored-cigarettes, as Michigan and New York state recently did. Flavors like buttered popcorn and mango helped create "an explosion" in teen vaping. But hundreds of thousands of teens already addicted to nicotine-and 9 million adults who vape--may simply replace vaping with tobacco products. By banning favored vapes the government may be "closing the shed door after the horse has gotten out."
Nobody vapes "because the flavor is so amazing," said David Marcus in The Federalist com. That's why the ban is so clueless."If kids want to taste bubble gum,they can buy,you know,bubble gum." Vaping giants like Juul need to be honest about the fact that they’re in the nicotine business, and monitor themselves accordingly. They should spend billions ensuring that stores don’t sell to minors instead of touting the "scientific conclusion"that e-cigarettes are safer than smoking. The burning involved in smoking cigarettes creates tar and a bunch of chemicals not present in e-cigarettes' watery vapor. True, but nicotine is also a dangerous and addictive drug and vaping liquid itself contains chemicals that damage blood vessels(血管)."The idea of safe smoking" is"a lie," and the vaping industry's fruit- and candy-flavored pods" are proof of evil intent."
"The massive increase in teen vapers" is a reasonable concern, said Robert Gebelhoff in Washington Post.com.But the evidence suggests that the lung illnesses that led the government to act were caused by black-market products cut with dangerous substance.Banning favored vapes will only drive more nicotine addicts and teens to the black market,which will be happy to provide fruity pods. Instead of banning flavors, the government "should empower the FDA to fully regulate the industry." That would let science,"not panic,guide our policy."

2 . The first patient who died on my watch was an older man with a faulty heart. We tried to slow it down with treatment, but it suddenly stopped beating completely. Later, whenever I would have a case like that one, I found myself second-guessing my clinical management. However, it turns out that thinking twice may actually cause more harm than good.
In a working paper, Emory University researchers found that when doctors delivering a baby have a bad result, they are more likely to switch to a different delivery method with the next patient, often unnecessarily and sometimes with worse results.
Because doctors make so many decisions that have serious consequences, the fallout from second-guessing appears especially large for us. A 2006 study found that if a patient had a bleed after being prescribed (开药) warfarin, the physician was about 20% less likely to prescribe later patients the blood thinner that prevents strokes (中风). However, if a patient was not on warfarin and had a stroke physicians were still no more likely to prescribe warfarin to their other patients.
These findings highlight interesting behavioral patterns in doctors. In the blood-thinner study, doctors were more affected by the act of doing harm (prescribing a blood thinner that ended up hurting doctors were more affected by the act of doing harm(prescribing a blood thinner that ended up hurting a patient) and less affected by letting harm happen (not prescribing a blood thinner and the patient having a stroke). Yet a stroke is often more permanent and damaging than a bleed.
But this phenomenon is not unique to medicine. ''Overreaction to Fearsome Risks'' holds true for broader society.
For instance, sensational headlines about shark attacks on humans in Florida in 2001 caused a panic and led the state to prohibit shark-feeding expeditions. Yet shark attacks had actually fallen that year and, according to the study, such a change was probably unnecessary given the extremely small risk of such an attack happening.
Humans are likely to be influenced by emotional and often irrational (不理性的) thinking when processing information, bad events and mistakes. As much as we don't want to cause an unfortunate event to happen again, we need to be aware that a worst situation that can be imagined doesn't necessarily mean we did anything wrong. When we overthink, we fail to rely on thinking based on what we know or have experienced. Instead, we may involuntarily overanalyze and come to the wrong conclusion.
I have treated dozens of patients who presented with the same illnesses as my first patient, who died more than a year ago. Instead of second-guessing myself, I trusted my clinical instinct (本能) and stayed the course. Every one of those patients survived. You should trust your instinct in your life, too.

3 . Professor Stephen Hawking recently came out with a serious warning for people. While at the Starmus Festival, a festival in Trondheim, Norway, celebrating science and the arts, Hawking warned people that the human race is in serious danger.
Hawking criticized President Donald Trump for denying climate change. Then the physicist warned the audience, “I am not denying the importance of fighting climate change and global warming, unlike Donald Trump, who may just have taken the most serious, and wrong, decision on climate change this world has seen.”
Hawking proposed that the leading countries should send astronauts to the Moon before 2020 to restart a movement of more exploration in space. BBC reported that Hawking suggested that we “build a lunar base in 30 years’ time and send people to Mars by 2025.”
According to BBC, Professor Hawking said, “Spreading out into space will completely change the future of humanity.” He continued, “I hope it would unite competitive nations in a single goal, to face the common challenge for us all.” The physicist shared more ideas to motivate the younger generation to continue exploring space. Hawking stated, “a new and ambitious space program would excite (young people), and stimulate interest in other areas, such as astrophysics and cosmology.”
Hawking also revealed his vision for other forms of energy that could move us to a new planet. He warned the audience, “The Earth is under threat from so many areas that it is difficult for me to be positive.” He continued, “Our natural resources are being drained, at an alarming rate. We have given our planet the disastrous gifts of climate change, rising temperatures, reduction of the polar ice caps, deforestation, and decimation (大量毁灭) of animal species. We can be ignorant, unthinking lot (人).”
The professor warned the audience that doing nothing would lead nowhere. He said, “If we succeed, we will send a probe (航天探测器) to Alpha Centauri within the lifetime of some of you alive today. It is clear we are entering a new space age. We are standing at the threshold (起点) of a new era. Human colonization and moving to other planets is no longer science fiction, and it can be science fact.” Hawking advised the audience to move to other worlds because we are running out of space.

4 . Kyle Cassidy and three other members of the Annenberg Running Group were stretching on the grounds of the University of Pennsylvania, waiting for a few latecomers. The Penn colleagues and other community members meet three days a week for a roughly 30-minute jog and an occasional lecture. That's right― during some runs, one of them delivers a talk. Topics range from the brain to Bitcoin.
But on this day last January, it would not be their normal run. The first clue that something was off was the man who sprinted past them. "Running at an amazing pace," Cassidy told Runner's World admiringly. Cassidy discovered why the sprinter was so fleet of foot when another man ran by, yelling, “Help! He took my phone and laptop!"
At that, the group did what running clubs do: They ran, trailing the suspect down the streets of Philadelphia until he ducked into a construction site. The runners split up. Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot （赃物）in a backyard.
No luck. So they decided to ask residents whether they'd seen the guy. When they knocked on the door of one row house, they were in for a surprise. Unknown to them, he had already emerged from the construction site—and was hiding behind a bush by that very house. As the owner opened the door, the suspect darted out from behind the bush ... and right into the arms of campus police, who'd joined the chase shortly behind the runners.
The members of this running group are not hard-core athletes. But they do understand the benefit of a little exercise. ''Running is typically a useless sport where you turn fat cells into heat," Cassidy told The Philadelphia Inquirer. "But occasionally it can be useful, and here was one of those opportunities."

5 . Time and how we experience it have always puzzled us. Physicists have created fascinating theories, but their time is measured by a pendulum (钟摆) and is not psychological time, which leaps with little regard to the clock or calendar. As someone who understood the distinction observed, ''When you sit with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like two hours. ''
Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age. They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass. For example, a day at the office flies compared with a day at the beach.
Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real idea of when we’ll arrive, we experience the trip as lasing a long time. But the return trip, although exactly as long, seems to take far less time. The novelty of the outward journey has become routine.
When days become as identical as beads (小珠子)on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day-- to stop time, so to speak.
Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems to be full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn't have to be.

6 . Learning a second language is tricky at any age and it only gets tougher the longer you wait to open that dusty French book. Now, in a new study, scientists have pinpointed the exact age at which your chances of reaching fluency in a second language seem to plummet: 10.
The study, published in the journal Cognition, found that it’s “nearly impossible” for language learners to reach native-level fluency if they start learning a second tongue after 10. But that doesn’t seem to be because language skills go downhill. “It turns out you’re still learning fast. It’s just that you run out of time, because your ability to learn starts dropping at around 17 or 18 years old,” says study co-author Joshua Hartshorne, an assistant professor of psychology at Boston College.
Kids may be better than adults at learning new languages for many reasons. Children’s brains are more plastic than those of adults, meaning they’re better able to adapt and respond to new information. “All learning involves the brain changing,” Hartshorne says, “and children’s brains seem to be a lot more skilled at changing.”
Kids may also be more willing to try new things (and to potentially look foolish in the process) than adults are. Their comparatively new grasp on their native tongue may also be advantageous. Unlike adults, who tend to default (默认) to the rules and patterns of their first language, kids may be able to approach a new one with a blank slate (石板).
These findings may seem discouraging, but it was heartening for scientists to learn that the critical period for fluent language acquisition might be longer than they previously thought. Some scientists believed that the brief window closes shortly after birth, while others stretched it only to early adolescence. Compared to those estimates, 17 or 18 — when language learning ability starts to drop off — seems relatively old.
“People fared better when they learned by immersion (沉浸), rather than simply in a classroom. And moving to a place where your desired language is spoken is the best way to learn as an adult. If that’s not an option, you can mimic an immersive environment by finding ways to have conversations with native speakers in their own communities,” Hartshorne says. By doing so, it’s possible to become conversationally proficient — even without the advantage of a child’s brain.

7 . A Bridge Linking Art and the Audience
According to a 2018 report, people aged between 16 and 24 make up about 15 percent of the population but only 10 percent of museum-goers. Similarly, people aged over 35 go half as much as you would expect from their population size. We have reached the point of recognising the disconnection between art and the audience but haven’t yet determined how to bridge the gap. Two answers to tackling this challenge lie in telling a greater diversity of art histories and communicating these stories in more accessible ways.
In 2018, a radio program called Art Matters was started with the aim of discussing art from a pop-culture viewpoint with topics that would engage younger and more diverse audience. It offers an accessible pathway to art history with conversations on different topics. Art history is about storytelling; art content shines when there is an effort to bring audience along for the discussion.
More traditional institutions are paying attention. Recently the Getty Museum issued a social-media challenge for people to recreate paintings using items they had at home. Users displayed incredible creativity, and the museum was flooded with submissions. This reaction proves that there is a potential desire for the audience to engage with art topics if the format is appealing. Since many people feel intimidated and think that there’s a base level of understanding required to join the conversation, the Getty initiative serves as a reminder that there are many pathways to engaging with it.
Another result of the Getty challenge was the exposure given to a diversity of artworks. The famous opera singer Peter Brathwaite, for example, made scores of attractive recreations highlighting centuries of black paintings. His efforts opposed the idea that there were not many historical paintings of black figures. It is extremely important that we do a better job of showing the complex and diverse stories that are represented in art.
Social media have offered a platform for people who have not traditionally had a seat at the table. Anyone can recognise a gap in the field and address it. Accounts have gathered tens of thousands of followers. They are the proof that there is hunger to hear these art histories, and these themes work brilliantly for museum programming.
But there is only so much that can be done without the museums and galleries changing meaningfully from within. We need to see a better balance of these stories represented in permanent collections. We also need a much wider diversity of people and interests represented on board. Ensuring that art-and writing and talking about art-is able to continue on the rising generation of storytellers, inside and outside of institutions, getting the funding and support they need to paint a brighter picture for the part.

| B．Fewer and fewer young people go to museums. |
| C．Art appears too distant from common audience. |
| D．Adult audience has a different understanding of art. |

8 . These days, it's not unusual to see middle-aged men collecting Star Wars action figures, office workers wearing Hello Kitty accessories, or celebrities like David Beckham playing with Lego bricks. It's becoming more and more common to see adults taking an interest in toys, comic books and the activities that are traditionally associated with children. This phenomenon has given rise to a new word: kidult.
What lies behind the phenomenon? One is about adults' nostalgia （怀旧之情）for the carefree days of childhood, and this is especially true with today's fast-paced, stressful lifestyles. Another is about a societal change in recent decades where people are starting families later. As a result, they have more time and money to spend on themselves. Some adults could only window-shop for their dream toys when they were kids, but now they can afford that radio controlled car or high-priced doll they have always wanted.
Businesses have been quick to exploit the kidult trend, and the number of toy stores that target adults has risen. Companies are repackaging products from past decades and also bringing out new ones for adults. Lego, for example, has brought out an architectural series featuring landmarks from around the world.
Society traditionally disapproves of adults who refuse to put aside childhood interests, viewing the refusal as a sign of social immaturity and irresponsibility. Those who agree with this view sometimes claim that kidults are suffering from the pop-psychology concept known as Peter Pan Syndrome, an anomaly （异常）that people remain emotionally at the level of teenagers. On a grander scale, these kidult opponents （对手）argue that such delayed adulthood causes couples to marry later and have fewer children. This in turn can lead to shrinking national economies, for there needs to be a generational replenishment （补充）
of the workforce.
From the standpoint of kidults, though, this phenomenon is seen as nothing but harmless fun. Kidults insist that having youthful interests keeps them young, happy and creative, and their refusal to conform to society's acceptable tastes shows independent thinking. Besides, they argue that being part of the social trend of delayed adulthood is not purely a personal choice. The real causes include expensive housing, increased educational requirements for employment and poor work opportunities.
Whether the kidult phenomenon will continue to grow or prove to be a passing trend is anyone's guess. As the debate about it continues, remember that there is nothing wrong with being young at heart.

9 . Pangolins (穿山甲) are the most trafficked (非法交易) mammals in the world and are facing extinction. To draw attention to these scaly (有鳞片的), anteater-like animals, a new wildlife documentary, Eye of the Pangolin, is attempting a unique way to inspire action and conservation. Partnering with the non-profit organization Pangolin. Africa, the documentary was made available on YouTube in May 2019. The intention is to reach communities wherever the Internet is available, especially African communities, who live near the animal’s habitats.
Over two years, the documentary crew traveled to South Africa, Ghana, Central African Republic and Gabon in search of the four unique species of pangolin, which has never been achieved before. Filmmakers Bruce Young and Johan Vermeulen say that they went into the shoot knowing relatively little about pangolins, but grew to respect and appreciate the animals. Getting close to the creatures over two years was a crash course in these secretive creatures. Johan Vermeulen said, "One thing however that might seem unimportant is that they are actually quite fussy eaters. You would think they would eat any type of ant, but they all prefer a specific type ant."
Pangolins are hunted illegally across Africa for their scales, which are used for traditional medicine, and their meat. In April 2019, Singaporean customs officials conducted two separate seizures of 24 tons of pangolin scales, which equals to the death of 69,000 pangolins.
Though the documentary focuses less on the trafficking of pangolins, and more on the animals in their natural habitat, the aim of the documentary is to inspire viewers around the world to call for action to end trafficking and protecting these unique creatures.
Filmed on location in South Africa, Ghana, Central African Republic, and Gabon, this powerful documentary is the story of two men on a mission to get all four species of African pangolin on camera for the very first time.

10 . Confused by food nutrition labels? You’re not alone. Now, researchers have suggested an alternative: labelling the amount and type of exercise needed to burn off the calories.
Current food and drink labels display nutritional information such as the amount of calories and fat. However, researchers led by Prof. Amanda Daley at Loughborough University say that these labels are having a limited effect on changing buying habits. Instead, they propose a labelling system called ‘physical activity calorie equivalent or expenditure’ (PACE) (体育活动热量当量), which shows how many minutes or miles of physical activity are needed to burn off the calories. For example, a small bar of milk chocolate contains 230 calories, which would take about 42 minutes of walking, or 22 minutes of running, to burn off.
They pooled the data from 14 previous studies which compared the impact of PACE labelling with that of other types of food labelling, or with no food labelling at all. They calculated that PACE labelling could cut a person’s daily calorie intake by up to 200 calories. “Public health agencies may want to consider the possibility of including policies to promote PACE food labelling as a strategy that contributes to the prevention and treatment of obesity (肥胖) and related diseases,” said the researchers.
The UK’s Royal Society for Public Health has already called for PACE labelling to replace the current system. However, not everyone is convinced. A spokesperson for the eating disorder charity Beat said: “We believe that anti-obesity campaigns that focus on weight instead of health are ineffective and that recommending more exercise is an ineffective and over-simplistic approach to a complex problem. Most urgently, public health campaigns must consider people’s mental as well as their physical health, moving from obesity-shaming to evidence-based campaigns that build confidence and support healthy eating.”
