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 . In the past few decades, great progress has been made in the field of space exploration, which has enabled mankind to have a deeper understanding of the Solar System, our place in it and in the universe. “We sent probes(探测器) to every planet in the Solar System. This is by far the best one,” said Clayton, vice president of Blue Origin. “Let's focus right now on protecting the Earth environment, and then we'll go from there. Space science and technology should be people-centric and application-centric, and focus on improving human life. We need to have a strong footing on the Earth, learn to solve the day-to-day problems of the society.”
“Space technology can help achieve the 17 sustainable development goals to be achieved by 2030 set by the United Nations. Satellite monitoring can really help with agriculture. ” said Victoria, CEO of a company working on sustainable development, “Through Global Navigation Satellite System, animals' movement information recorded on self-recharging devices can be transmitted to the company server. Farmers can be alerted in real time if anomalies(异常现象）are detected. We can use it to ensure the traceability of the entire meat chain. As a result, it enables consumers to know that the beef they are eating does not come from protected areas or the cattle don't contribute to deforestation. ”
As early as 2007, Michael Griffin, former Administrator of NASA, put forward the concept of the “space economy” in a speech. He is very optimistic about the market prospect of commercial space and said, “According to the latest data, the global space industry could reach $1 trillion in 2040, up from $ 378 billion currently. I believe more business models and space activities will be created in the future to achieve the economic scale of $1 trillion. ”
As an entrepreneur(创业者）herself, Victoria thinks the thriving space market will bring countless opportunities for entrepreneurs. She mentioned future settlements on Mars or on the Moon. “If we are going to develop a new society outside the Earth, we will need all types of applications and all types of startups. But coming back to the Earth, there are so many problems that need to be solved, and space technology can really help with that.”

3 . With the world’s attention on vaccines (疫苗), now feels like a good moment to sing the praises of an often forgotten contribution to their development. Three hundred years ago this month, Lady Mary Wortley Montagu got her daughter inoculated (接种) against smallpox, making her child the first person in the West to be protected in this way. Without Montagu’s willingness to adopt a practice she had learned from other cultures, the introduction of vaccines around 80 years later would never have taken place.
Montagu first witnessed inoculation when she accompanied her husband to Turkey in 1717. Inoculation had started in Asia, probably in China, as early as the 10th century AD. Montagu observed how older women in Turkey took a tiny amount of pus (脓) from a person with smallpox. They then used needles to make cuts on people’s wrists and ankles and added the pus to their bloodstream. This helped people gain immunity from future infection.
Like other visitors to the country, Montagu took steps to ensure that her son was inoculated in Turkey. This worked well, but she knew that trying it in England would be far more challenging. Inoculation performed by unlicensed amateurs would threaten doctors’ professional standing and potentially rob them of valuable income. Churchmen also disagree with the practice, as they saw it as going against nature.
Back in England, Montagu observed the increased severity of smallpox infections. Eventually, in April 1721, she decided to use the Turkish practice to have her daughter inoculated, because she believed that the rewards would outweigh the risks. After a safe time had passed following the inoculation, Montagu allowed doctors to examine her daughter.
Doctors in Britain gradually accepted the practice. About so years later, a pioneering physician found smallpox vaccines to destroy smallpox completely. As early as last century, academics argued that Montagu was no more than an enthusiastic amateur. In truth, she made a vital scientific contribution towards finding the cure for smallpox.

4 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.
The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.
The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.
Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.
“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.
“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

5 . If you think you’d like to live on Mars, you may have that possibility by 2023. A Dutch company called Mars One will soon advertise for people interested in colonizing (开拓) Mars. If you have all the necessary skills, you could be one of the first colonists. Are you ready for the challenge?
You won’t have to pay for the mission to Mars. Mars One has already received money from some donors and is hoping to get more from TV viewers who will become interested in the show where all applicants have a debate for the rare chances.
The main responsibility of the first colonists is to create an artificial environment on Mars where there is no air to breathe and no land to farm. Scientists know it’s quite possible because something similar has already been done in Antarctica.
Another problem is that space travel to Mars takes nearly a year to get to Mars and the colonists will live the rest of their lives there. When a human lives in an environment without gravity or with low gravity for a long time, the systems in the body weaken. Luckily, spinning (旋转) the spaceship can create artificial gravity, and artificial gravity can ease these problems. It will also be difficult for Mars colonists to be far from home, living in small spaces, and seeing the same people over and over. Colonists with depression could put the mission in danger. Fortunately, a few years ago, a joint Russian and European project called the Mars500 Mission studied people’s reactions in a Mars-like environment. It is viewed as a great success because scientists were able to see how people handle emotional and physical stresses.
Recent studies show that seven percent of people would want to go on such an adventure.
Mars One will soon start accepting its first colonists. Are you interested?

6 . Indonesian university student Tyas Sisianindita spends about eight hours a day on her phone. That time includes watching videos, chatting with friends and using social media. "At night, when I can't sleep, I can use my phone for up to five hours," she said, noting she checks her phone countless times from morning until night. She even checks it while in class.
Tyas goes to the University of Indonesia, where a team of students recently developed a device meant to fight phone addiction. The students spent three months creating the device, which can help internet users like Tyas diminish time they spend looking at their phones.
Inventor Irfan Budi Satria led the development team. The device is called “Nettox", which combines the words “internet" and "detox (排毒)". Users wear it on their arm. The device has a sensor that measures hemoglobin (红蛋白) oxygen levels and changes to the heart rate called HRV. Studies have found that using a mobile phone for long hours can lower HRV levels. The Nettox device makes a sound when HRV and blood oxygen levels fall, which reminds wearers to stop using their phones.
For people between the ages of 18 and 25, the HRV should stay above 60. At a recent trial, Tyas' HRV reading was 44.
Internet addiction is a growing social issue in Indonesia. In October, two teenagers were treated for their addiction to internet gaming, media reported.
Irfan Budi Satria's team is working to improve Nettox's accuracy. HRV readings can change depending on whether the user is a man or woman, and what their body shape and health conditions are.
The team aims to get a patent for their invention with the university by next year. Irfan says Nettox is for people already trying to change their behavior. "Our goal is to help people who want to free themselves from internet addiction," he said.

7 . When you hear the beginning of your favorite song from the radio, suddenly your neck is covered in goose bumps.
It's such a thing that a group of scientists call “skin excitement”—a feeling of cold caused not by a drop in temperature or sudden scare, but by the sense of beauty. “Skin excitement” can come from a song, a painting, a moving movie scene, or even a beloved memory-pretty much anything that causes the giving out of pleasure-soaked dopamine in your brain. But it does not come for all of us.
Your favorite music uncovers a lot about your personality，and so does how you respond to that music. Studies suppose that as few as 55 percent of people experience “skin excitement” when listening to music. And if you count yourself among this group, the goose bumps on your skin aren't the only giveaway—scientists can read it in your brain, too. In a new study published in the journal Social Cognitive and Affective Neuroscience, Harvard researchers performed brain scans on 10 students who said they reliably got cold when listening to music, and 10 students who didn't. They found that the cold-prone brains may really be excited by stronger emotions.
Cold-prone brains are generally more likely to show stronger emotional intelligence than no-cold brains. Cold-prone minds tend to have unusual active imagination, reflect more deeply on their emotions, and appreciate nature and the beauty of music and art to a stronger degree than no-cold brains.
So, what type of music causes the chills? It seems that the type is not so important; participants in the new study reported getting cold from songs of every kind. And any song connected with a strong emotional memory of the listener can produce the most reliable results. For me, that's the song Sailing to Philadelphia by Mark Knopfler, which I listened to as a kid in the car with my dad, on the way to the summer camp.

8 . A shocking news report has revealed that more than one in five species of maple trees faces extinction, warning that 75% of the threatened species are “geographically restricted” in their native regions.
The trees are experiencing a vast decline in habitat, due to urban development, wood harvesting and agricultural expansion. Time is running out for the world's biodiversity. Every recent survey of plants and animals in the wild points to this. This is happening nearly everywhere rarer maples exist. And because of climate change, the narrow habitats that support species at the edges of dry places and at the tops of mountains are quickly disappearing.
The trees can be found in subtropical and tropical regions, as far south as Indonesia. The only species found in the UK, the field maple is not under threat. Not only are the trees a popular attractive feature in parks and public spaces, but they are a key part of the natural ecosystem in woodlands, as well as being an important wood crop in several countries. Although the sugar maple in North America, which produces maple juice, is not endangered, two of the closest relatives to the species are endangered.
The report notes that conserving at-risk species in their natural habitat is the best conservation tactic. But collections in botanical gardens and seed banks-called "ex situ collections" can act as insurance policies against extinction. There are currently 14 species of maple, including four that are critically endangered, which are absent from these types of collections.
One species in Mexico, the Acer binzayedii, is in “desperate need of conservation"”despite only being discovered in 2017. “It is at risk from climate change in its cloud forest habitat and threatened by logging and forest fires while it is also absent from 'ex situ collections',” the report adds. The report recommends developing conservation plans, monitoring species currently not at risk to ensure populations are maintained, and adding those missing maple species to seed banks.

9 . Scientists say baby sharks are at risk of being born smaller and without the energy they need to survive because of warming oceans from climate change. Scientists studied epaulette sharks, which live off Australia and New Guinea. They found warmer conditions sped up the sharks' growing process, which meant the sharks were born earlier.
John Mandelman, chief scientist of the Anderson Cabot Center for Ocean Life said the findings could be used in the study of other sharks.
Mandelman said it is widely believed that epaulette sharks are "hardy," or able to survive difficult conditions. "What it means is that this species is more vulnerable than we thought, and this could be true of other sharks," he added.
The scientists studied 27 sharks using the New England Aquarium's reproduction program. Some were raised in average summer water temperatures. Others were raised in higher temperatures. They found the sharks raised in warmer temperatures weighed much less than those raised in average temperatures.
One study this year found that worldwide numbers of oceanic sharks and rays dropped more than 70 percent between 1970 and 2018. Overfishing is a main concern, while climate change and pollution also threaten sharks.
Carolyn Wheeler, a doctoral student at the University of Massachusetts Boston and the author of the epaulette shark study, said while all the sharks survived, those raised in warmer temperatures were not strong enough to survive for long in the wild. She added that if the sharks are born smaller than usual "they are probably going to have to start looking for food sooner — and they're going to have less time to adjust to their surroundings."
Mariah Pfleger, an ocean scientist said the study should serve as a warning to ocean governing agencies that careful supervision is needed to prevent the loss of more sharks." This study further shows that sharks will not be immune to a warming ocean," Pfleger added.

10 . In Japan, some workers who regularly drink beer at the end of the day are giving their livers a rest by turning to beer that is free, or nearly free of alcohol.The liver is the organ that works to remove alcohol from the body. Masuda, one of beer lovers, said he is paying more attention to his health now that he is older.
Asahi is a large beverage company in Japan, which made 20 percent more money from low-alcohol beer in 2020 compared to the year before. Kirin is another company that makes things to drink. It saw sales grow by 10 percent last year and expects another increase this year.
The increase in sales of non-alcoholic beer might be the result of many Japanese people spending more time at home. In the past, they would order beers together while going out. More people are trying to stay healthy as well. Also, fewer people are drinking beer, as wine and other alcoholic drinks become more popular. But the new interest in low-alcohol beer has helped the beverage industry in Japan.
In recent years, many companies started making non-alcoholic beers. They caught on in places like Australia and Germany but not in Japan – until this year.
The chief of Suntory, another large beverage company in Japan, said people only responded to non-alcoholic beer advertising when the product started to taste better. Many people agree that today's non-alcoholic beers taste better than they used to. Asahi's "Beery" has very little alcohol. But it is supposed to have more taste than earlier versions of low-alcohol beer because of a new way of removing the alcohol. The company plans to offer more low-alcohol beers in coming years.
Kazuo Matsuyama is marketing chief for Asahi, who said most beer companies used to advertise to people who had a drink every day. That was about 20 million people. But there are about 80 million people in Japan between the ages of 20 and 60." But now we need to look at others." Matsuyama said.
