1 . Have you ever heard about Black Friday and Cyber Monday? Surely, they are all about finding the best deals on holiday gifts for yourself and family members. And have you heard about GivingTuesday? Here is something about it!

GivingTuesday is observed annually on the Tuesday after Thanksgiving, which encourages people to help those in need by making financial donations or doing good in their local community. The “Global Day of Giving” was started in 2012 by New York City nonprofit 92nd Street Y and the United Nations Foundation.

Unlike Black Friday, GivingTuesday serves a more altruistic purpose. In its first year, the movement brought in almost $10 million for charities, and things have only improved since. In 2019, many GivingTuesday social media campaigns worldwide helped raise an amazing $ 1.9 billion from 27 million donors! Over the past five years, many higher education institutions have also been using the Tuesday after Thanksgiving to ask alumni for donations. In 2019, the University of Michigan, which calls it Blueday, received 5887 gifts totaling over $4 million, while Pennsylvania State University raised $710 000 to benefit over 85 University programs.

Though donating money certainly helps, there are many other ways to support the great cause, especially during the COVID-19 pandemic. You can video tutor kids struggling with online learning, or team up with an adult to get groceries or medications for an elderly neighbor. Alternatively, call on your peers to help you with a service project that addresses an issue close to your heart, or pick one from the several ideas suggested on the GivingTuesday website. You can also donate your gently-used clothes and toys to local shelters, or mail a handwritten note to a grandparent or a friend you miss seeing.

2 . The joy of giving is real, according to a study. Research presented in the Journal of the Association for Psychological Science shows that those who give gifts are happier — and happier for longer — than those who receive gifts.

Researchers conducted two studies last year. In one，participants were given $5 every day for five days and were required to spend the money on the same thing each day. Some participants were required to spend the money on themselves, while others were required to give to make a donation to charity. In a second experiment that was done online, participants played 10 rounds of a word puzzle game and each won 5 cents per round, which they could keep or donate.

In both experiments, participants reported their overall happiness. Those who donated their money showed that their happiness declined at a much slower rate than those who kept the money or spent it on themselves.

The researchers note that when people focus on an outcome, they can easily compare outcomes, which may diminish their sensitivity to each experience. When people focus on an action, they may focus less on comparison and instead experience each act of giving as a unique happiness-inducing event. Further analyses ruled out some potential alternative explanations, such as the possibility that participants who gave to others had to think longer and harder about what to give, which could promote higher happiness.

The results are especially interesting because according to one of the researchers, Ed O’Brien of the University of Chicago Booth School of Business, they conflict with past research. “If you want to sustain happiness over time, past research tells us that we need to take a break from what were currently consuming and experience something new. Our research reveals that the kind of thing may matter more than assumed: Repeated giving, even in identical ways to identical other，may continue to feel relatively fresh and relatively pleasurable the more we do it,” O’Brien said.

So for all the holiday gifts you give this season, expect to feel happy and know that feeling is going to stick around for a while.

3 . 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.

4 . Experts are warning about the risks of extremely picky(挑剔的)eating after a teenager living on a diet of chips and crisps developed lasting sight loss. Eye doctors in Bristol cared for the 17-year-old after his sight had gone to the point of blindness. Tests showed he had serious vitamin deficiency(缺乏). Dr. Denize Atan, who treated him at the hospital, said, “His diet was basically a portion of chips from the local fish and chip shop every day. He also used to snack on crisps and sometimes white bread and ham, and not really any fruit and vegetables.”

The teenager saw his doctor at the age of 14 because he had been feeling tired and unwell. At that time he suffered from vitamin B12 deficiency, but he did not stick with the treatment or improve his poor diet. Three years later, he was taken to the Bristol Eye Hospital because of progressive sight loss.

He was not overweight or underweight, but he had lost minerals from his bones, which was really quite shocking for a boy of his age. In terms of his sight loss, he met the standards of being blind. “He had blind spots right in the middle of his sight,” said Dr Denize Atan, “That means he can’t drive and would find it really arduous to read, watch TV or recognize faces.”

Dr Denize Atan said that parents should learn about the harm that can be caused by picky eating, and turn to experts for help. For those who are concerned , she advised, “It’s best not to be anxious about picky eating , and instead calmly introduce one or two new foods with every meal.” She said multivitamin tablets can supplement(补充) a diet, but cannot take the place of eating healthily. “It’s much better to take in vitamins through a varied and balanced diet,” she said, adding that too many certain vitamins , including vitamin A, can be harmful ,“so you don’t want to overdo it.”

5 . Yoga originated in ancient India some 5,000 years ago. It has since spread across the world to many cultures. In the last few years, yoga has been offering classes aiming at the hearing impaired(听障者).

Most yoga classes are based on a model in which students learn by listening to their teacher's statements. As many yoga positions limit the ability to see the teacher, hearing-impaired participants who rely on lipreading (唇读) or sign language are left on their own during a class.

Recognizing the hearing -impaired are eager to attend yoga classes, one British yoga studio determined to fill the lack. Bethaney Mouzer, a yoga instructor launched Sign Yoga in 2019, with the goal of bringing yoga to people for whom the practice may have previously been forbidden.

Mouzer, who was born to non-hearing parents, is used to existing two worlds. After becoming a yoga teacher in 2015, she fielded requests from many people who were interested in yoga, but struggled to find teachers to accommodate their needs.

At first Mouzer started out small, holding single-day workshops at local studios in Birmingham and Worcester, where she signed continuously throughout the classes. The sessions were an immediate hit, and Mouzer began posting classes online via a Facebook page called Sign Yoga. Finally, once there was enough demand, Mouzer also started teaching in London.

Today, Sign Yoga is a mostly online company, with live Zoom classes and pre - recorded lessons accessible to students, as well as occasional in-person classes held in local parks. Mouzer ran a Deaf Accessible Yoga Teacher Training workshop in May.

8 . Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.

Artificial light at night can affect every aspect of insects' lives, the researchers said. "We strongly believe artificial light at night — in combination with habitat loss, chemical pollution.invasive (入侵的) species, and climate change — is driving insect declines, " the scientists concluded after assessing more than 150 studies.

Insect population collapses have been reported around the world, and the first global scientific review published in February, said widespread declines threatened to cause a "catastrophic collapse of nature's ecosystems".

There are thought to be millions of insect species, most still unknown to science, and about half are active at night. Those active in the day may also be disturbed by light at night when they are at rest.

The most familiar impact of light pollution is moths (飞蛾) flapping around a bulb, mistaking it for the moon. Some insects use the polarisation of light to find the water they need to breed, as light waves line up after reflecting from a smooth surface. But artificial light can scupper (使泡汤) this. Insects are important prey (猎物) for many species, but light pollution can tip the balance in favour of the predator if it traps insects around lights. Such increases in predation risk were likely to cause the rapid extinction of affected species, the researchers said.

The researchers said most human-caused threats to insects have analogues in nature, such as climate change and invasive species. But light pollution is particularly hard for insects to deal with.

However, unlike other drivers of decline, light pollution is relatively easy to prevent. Simply turning off lights that are not needed is the most obvious action, he said, while making lights motion-activated also cuts light pollution. Shading lights so only the area needed is lit up is important. It is the same with avoiding blue-white lights, which interfere with daily rhythms. LED lights also offer hope as they can be easily tuned to avoid harmful colours and flicker rates.

10 . It is sometimes jokingly said that you may skip a meal a day without any adverse effect but skip using your WeChat for an hour and you will feel distinctly unwell. It is an acknowledgement of the fact that the app is no longer only a fun tool but an essential part of life for millions.

Launched in January 2011, this messaging, social media and mobile payment app today has more than 1 billion individual users. People use it for everything, from applying for a business license to booking a hospital appointment to keeping up with family and friends, shopping and paying bills—activities that are part and parcel of our everyday life.

When it was first introduced, WeChat was only an app supporting voice, video, picture and text messages between two persons or among a group. But today it has become ubiquitous.

In the past, people carried their wallet and keys with them wherever they went; today, a smart phone with WeChat installed is all they need in daily life. Its functions like Moments and mini programs and the official WeChat accounts of government agencies and companies have made communication and public services accessible and convenient like never before.

WeChat is also widely used by enterprises. Figures from Tencent show there are around 15 million WeChat official accounts, which enjoy 5 billion followers. Most businesses use their WeChat groups as a standard marketing kit. This has immensely reduced advertising, marketing and communication costs, and in the background of the novel coronavirus disease, made operations faster, contactless and safe.

However, there are concerns about the downsides of WeChat, such as addiction among primary school children. Equally serious is the misuse of WeChat for fraud or instigating crimes. However, it has to be kept in mind that these fallouts are not really the fault of WeChat, but due to the misuse of the app.

If we learn to temper our use of messaging apps with prudence and pragmatism, we could be looking forward to yet new conveniences and experience in this decade with the rapid development of 5G technology and artificial intelligence. Ultimately, the choice is ours, whether to use WeChat or any other new invention, wisely or wantonly.
