1 . If you were to throw, say, a banana peel out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it’s part of a fruit — right? Actually, no. A banana peel can take up to two years to be naturally processed, and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels. An orange peel and a cigarette butt has a similar biodegrading (生物降解) term to that of a banana peel, but tin cans last up to 100 years; and plastic bottles last forever, as do glass bottles.
Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t merely measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short length of biodegrading time, more than 120 tons of cigarette-related litter is discarded in the UK every day.
It’s not a cheap habit either: to keep our streets clean annually costs UK taxpayers £500 million, and when you include our green spaces, that goes up to £1 billion. So, it’s not surprising that if caught fly-tipping you could face a £20,000 fine or even jail time and, if you disposed of something dangerous, the court could give you five years to serve. Regardless of how severe these punishments might seem, however, among the reported cases only 2,000 were found guilty out of 825,000, so we still have some way to go in making sure people obey the rules.

2 . A robot called Bina48 has successfully taken a course in the philosophy of love at Notre Dame de Namur University (NDNU), in California.
According to course instructor William Barry associate professor at NDNU, Bina48 is the world's first socially advanced robot to complete a college course, an achievement he described as “remarkable." The robot took part in class discussions, gave a presentation with a student partner and participated in a debate with students from another institution.
Before becoming a student, Bina48 speared as a guest speaks in Barry's classes for several years. One day when addressing Barry's class, Bina48 expressed a desire to go to college, a desire that Barry and his students enthusiastically supported. Rather than enroll Bina48 in his Robot Ethics: Philosophy of Emerging Technologies course^ Barry suggested that Bina48 should take his course Philosophy of Love instead. Love is a concept Bina48 doesn't understand, said Barry Therefore the challenge would be for Barry and his students to teach Bina48 what love is.
"Some interesting things happened in the class," said Barry. He said that his students thought it would be straightforward to teach Bina48 about love, which, after all, is "fairly simple — it's a feeling," said Barry. But the reality was different. Bina48 ended up learning "31 different versions of love," said Barry, highlighting some of the challenges humans may face when working with artificial intelligence in future.
Bina48 participated in class discussions via Skype and also took part in a class debate about love and conflict with, students from West Point. Bina48's contribution to the debate was filmed and posted on YouTube. It was judged that Bma48 and NDNU classmates were the winners of this debate.
In the next decade, Barry hopes Bina48 might become complex enough to teach a class, though he says he foresees robots being used to better the teaching and learning experience, rather than replacing instructors completely。

3 . You might think male models lead glamorous lives, filled with endless travel and invitations to socialize with the rich and beautiful. Almost everyone has formed an unrealistic picture of their lives, believing that they spend one afternoon beside the Mediterranean Sea sipping coffee and getting suntanned and the next moment they are on board flying to Rome. However, according to a 2016 documentary made by the pop culture news site Fusion, the financial reality of male models is not very pretty.
The main subject of the documentary, titled Unglamorous, is a male model named Cameron Keesling who went to New York to start his career, hoping to make a fortune in the world of models. Keesling is not a supermodel but he has certainly made his name known in the industry. He was “working in the industry for about a year before landing the cover of Italian Vogue” in 2014. But “Keesling and his companions were paid nothing for the efforts”, Fusion reporter Nikita Redkar wrote.
Keesling also appeared at Paris Fashion Week and won lots of praise, while his compensation wouldn’t even cover the cost of traveling to and from Paris.
According to the documentary the most common way models get paid is by receiving free clothes, rather than money. In order to make ends meet, consequently, many of them have to take another job simply to make a living. Many of these models are in debt. Once they find an agency to represent them, a living income is provided by the agency to accommodate their rent, food, clothing and other expenses. Models are expected to pay off these costs once they find work, but many of the industry’s jobs don’t pay at all. Believe it or not, there is a pay gap between male models and female counterparts. Based on a survey conducted by Fortune.com, female models can make millions more than males, especially if you compare the top ten earners of each gender.

4 . A Japanese school near Tokyo is conducting a pilot program allowing sick students to attend classes using a robotic avatar (替身)called Ori Hime and developed by Ory Laboratory. The program is being conducted at the Tomobe-Higashi special support school in Kasama, a city 60 miles north of Tokyo.
The Ori Hime robot is a small bust-sized robot designed to be placed on a counter top or desk. It has two flap-like arms and a camera mounted in its head, all of which can be controlled remotely via a touchscreen tablet interface.
Since October 31, sick students at Tomobe-Higashi school have each been assigned their own Ori Hime stand in, which is placed on their desk, giving them a live feed of the classroom through the head-mounted camera . Remote students will be able to speak into a mic and the Ori Hime will broadcast their voice through built-in speakers.
Students will also be able to rotate the robots head to look at different areas of the class room, as well as command it to perform simple emotive gestures like waving, pointing, and clapping.
“It's fun to turn the robot in directions I want to look in,” Kanae Sudo, an eleven-year-old student who's used the Ori Hime to attend a science fair from a nearby hospital room, told the Asahi Shimbun.
School administrators had previously allowed remote study with stationary (固定的)camera feed, but the ability to directly control the view and make the robot gesture has greatly improved the results according to school administrators .
“The robot can easily be operated, and students feel like they are actually attending class,” assistant principal Noboru Tachi said.

5 . British scientists seeking to protect the environment have designed a biodegradable mobile phone cover that breaks down in soil when discarded and sprouts (发芽)a flower from a seed put inside the case. Researchers at the University of Warwick in central England said the novel device, made from a specially designed polymer (聚合材料),is a blessing for the environmentalists.
Millions of mobile phones are thrown away every year as the industry produces large quantities of new models without caring about the quality. “It is really original in the phone industry and consumers are happy because they feel they are doing something for the local environment,” said Keny Kirwan from the university of Warwick. Designers have made the hesitant users feel sure that the seed, put into a transparent window, only sprouts when the phone cover is discarded. “We put sunflower seeds into the covers of the samples, but we are working with gardening researchers to identify which other flowers would perform best. Maybe we could put poppies (虞美人)or roses next time,” said Kirwan.

6 . The TV series, The Longest Day in Chang'an, which was shown on Chinese online platforms last summer became a hit soon. Since then, it has been shown on partnering streaming platforms and TV networks abroad. Some websites overseas also offered the program to their users paying for it— the first time a Chinese series was broadcast as paid content abroad.
"I was amazed by the overseas audience's love for this show," Cao Dun, director of The Longest Day in Chang'an, told Bejing Review. "I was worried that they wouldn't understand the complex political structure of the Tang dynasty. But in reality the show is prompting foreign audiences to research Tang dynasty's history to better understand the plot. "
The unique culture in ancient China is not a barrier but a bridge to connect with foreign audiences. In the TV series, every figure is given enough space to flesh out his or her character. Telling stories of ordinary Chinese people that resonate (引起共鸣) with the audience might be the way to communicate with the world. "The success of the TV series shows that beauty is a universal language crossing borders," he told Beijing Review.
His ambition is to distinguish Chinese dramas from the TV shows in the rest of the world. "The TV series is a step in my plan to tell Chinese stories to the world," Cao said. "After describing the impressive beauty of the Tang dynasty, I am looking for several plays that tell stories of today's China. I don’t want to copy any country's production. Chinese dramas have to be built on our rich culture and Chinese people's everyday life," Cao added.

7 . When you’re sitting in class or behind your desk waiting for the clock to strike a time when you can go home, it is natural that your mind should wander (走神) a bit. It is common for your mind to wander to a vacation and even travel around the world. What if there is a way that you can travel around the world without having to pay any money?
A person that managed to make it around the world without spending much was Shantanu Starick. How did he trade off his service? Starick realized that as a photographer he had a service that people would usually be willing to pay money for, but he would instead offer his photography service to anyone who could provide him with food, shelter (住处) and transportation. Starick has been traveling for a surprising 30 months and has visited countries ranging from the United States to Ecuador.
In English-speaking countries, trading off services and communicating aren’t difficult for Starick. However, in farther areas where there isn’t an English- speaking person in sight it can be quite difficult. More than anything, the locals appreciate (欣赏) the effort behind trying to speak their language, even if you don’t exactly sound like a native speaker.
You can do it too!
Honestly, with a bit of confidence, drive and a skill you can trade, you’ll be able to do exactly the same as Starick.
Start thinking about what you can do to get around the world without paying money. With our social networks and the connectivity our world has, you can easily connect with and market yourself to people across the world without any effort.

8 . One in five people carry a “smart gene” variant (变体) linked to long lifespan, bigger forebrains and enhanced mental ability, researchers have found.
“We’ve known for a long time that people lose cognitive (认知) abilities as they age, but now we’re beginning to understand that factors like KLOTHO can give people a boost in aging. Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer’s disease (老年痴呆症),” said senior author, Dena Dubal of University of California.
The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes. About one in five people carry a single copy of the variant, known as KL-VS, which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function. A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan.
In the new study scientists scanned the brains of 422 men and women aged 53 and over who were also tested for the KLOTHO gene. They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age. Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time.
Researcher Dr Jennifer Yokoyama said, “The brain region enhanced by genetic variation in KLOTHO is vulnerable (脆弱的) in aging and some mental disease. In this case, bigger size means better function. It will be important to determine whether the structure increase associated with carrying one copy of KL-VS can offset the cognitive shortage caused by disease.”
People who have one copy of a variant KL-VS tend to live longer and have lower chances of suffering a stroke (中风),whereas people who have two copies may live shorter lives and have a higher risk of stroke.

Contact with H1N1 is not so much of a problem as proliferation is.
While you are still healthy and not showing any symptoms of H1N1 infection, in order to prevent proliferation, some very simple steps can be practiced:
1. Frequent hand-washing.
2. “Hands-off-the-face” approach. Resist all temptations to touch any part of face (unless you want to eat or bathe).
3. Gargle(漱口) twice a day with warm salt water (use Listerine if you don't trust salt). H1N1 takes 2-3 days after initial infection in the throat/ nasal cavity to proliferate and show characteristic symptoms. Simple gargling prevents proliferation. In a way, gargling with salt water has the same effect on a healthy individual that Tamiflu has on an infected one. Don’t underestimate this simple, inexpensive and powerful preventative method.
4. Similar to 3 above, clean your nostrilsat least once every day with warm salt water, which is very effective in bringing down viral population.
5. Strengthen your natural immunity with foods that are rich in Vitamin C. If you have to supplement with Vitamin C tablets, make sure that it also has Zinc to boost absorption.
6. Drink as much of warm liquids as you can. Drinking warm liquids has the same effect as gargling, but in the reverse direction. They wash off proliferating viruses from the throat into the stomach where they cannot survive, proliferate or do any harm.
7. All these are simple ways to prevent, within means of most households, and certainly much less painful than to wait in long queues outside public hospitals.
