Compared to other causes of natural disasters, volcanoes offer clues only when they are about to erupt. Now, however, developments in monitoring systems have allowed scientists to develop sensors to detect and forecast eruptions more accurately.
University of Cambridge volcanologist Marie Edmonds says that scientists are now able to use very accurate sensors to monitor the gases volcanoes give out, which can give clues on the location of the magma. The sensors help with prediction because different gases are released at different stages of an eruption. When magma rises, pressure is released along with gases. Carbon dioxide is released early on and then, as the magma goes higher, Sulphur dioxide is released. The ratio of the two gases is used to detect the location of magma relative to the surface, telling researchers the coming of the eruption.
Edmonds is connected to an international group known as the Deep Carbon Observatory that has worked to put new gas sensors on fifteen of the most active and dangerous volcanoes to improve the forecasting of various types of eruptions. The gas sensors continually measure water vapor, sulphur dioxide, and carbon dioxide. They are placed inside large boxes with surface antennae and buried underground. Advances in electronics have increased their accuracy and lowered their cost, allowing more of them to be used worldwide.
Putting these sensors atop active volcanoes is dangerous. Scientists wear reflective suits that protect against heat, plus gas masks for protection from dangerous gases. They sometimes hike long distances in remote areas to reach a site. However, according to Edmonds, the work they do to save people’s lives makes a dangerous job worth it. She enjoys doing something that helps people.
Edmonds’ team has also attached sensors to a certain plane to measure gases released from a Papua New Guinea volcano for a short time, a technique developed to gather “snapshots” of the activity. These snapshots help researchers to better understand activities that lead to eruptions.

Have you got an addictive nature? Are you unable to stop yourself joining in your favorite computer games? This probably describes most of us because its only human nature to not want to miss out on something that everyone else is talking about.
Most crazes arrive suddenly and enthusiasm for them spreads quickly. They become a talking point on social media; we read about them, give them a try and, before we know it, we are hooked (钩住). In the past, these have been objects such as toys and games. Maybe you were the proud owner of a Rubik’s cube, which became the best-selling toy of all time-around 350 million have been sold so far.
Now, technology is driving the latest crazes. Games such as Angry Birds and Minecraft are crazes available on smartphones and computers that have been hard to put down.
Our addiction to crazes has been analyzed by scientists. One of them, Dr Ben Michaels, a clinical psychologist, explains that we want to experience the benefit that another person, or group of people, have experienced from something and this “hooks into an ancient evolutionary (进化的) fear of being left behind or abandoned by our tribes”; we have to join in or lose out.
Although becoming addicted to a computer game might not seem like a ‘benefit’, it can at least give you popularity among your friends. It allows you to learn new skills and gives you something to talk about at parties!
But fashions come and go and most crazes are just a flash in the pan so if one of them is not your cup of tea, don’t worry: there’ll be a new craze arriving very soon. Look at the addiction to loom bands (橡皮筋) - those little bands you could make jewellery and other things out of. For a brief period they were the must-have item for any schoolchild, now they’re the bargain bucket item in a discount shop or worse still, trash filling up our landfill sites!

Picture a young Chinese woman in a field, dressed in traditional hemp (麻布) clothing, as she picks flowers to create makeup for her cheeks. Imagine the same person making a bamboo sofa, cooking soy sauce and cooking up all sorts of delicious dishes.
It may sound hard to believe, but such a person exists in modern China, and her name is Li Ziqi. On Dec 14, she won Person of the Year in the category of cultural influence awarded by China Newsweek.
With a fan base of more than 21 million people on Sina Weibo and 7 million flowers on video-sharing site YouTube, Li has made a name for herself in a series of videos that show off a pre-industrial Chinese way of life in rural Sichuan province. “I want to do my part to let more people know about Chinese culture,” the bogger told China.org.cn. “Much of the popularity of my videos owes to the attraction of Chinese culture.”
Li sems to be a master of all kinds of sills—cooking, painting, designing and farming. She raises silkworms to sew a quilt for her grandmother and grows plants. Many videos show her picking seasonal ingredients from her own garden and cooking them up with her wood-fired work. A warm bowl of soup for the winter, a lighter plate of noodles for the summer, Li follows the seasons in her cooking, as China’s traditional 24 solar terms also do, and makes food suitable for the particular climate.
“She told the stories of China’s culture and that of China.” the official Sina Weibo account of China Central Television noted. The success of Li Ziqi also comes from her “passion for life, for her home and for her culture”. Indeed, Li’s simple pleasures amaze people living in the hustle and bustle of big cities. “She leads a life that many dream of, but don’t dare to give up their current life in exchange for,” iFeng.com wrote. Her handmade lifestyle is a fantasy for many. “In today’s society, many feel stressed,” she told the South China Morning Post. “When they watch my videos at the end of a busy day, I want them to relax and experience something nice, to take away some of their anxiety and stress.”

The act of social distancing has become an effective protective measure against the novel coronavirus and a part of everyday life across the world. Many countries have launched different social distancing measures. Some are strict while others are creative. Let’s take a look at three special quarantine (隔离) measures around the world.
Panama
With more than 3,000 confirmed cases by April 12, Panama has announced strict quarantine measures. One of them is to separate people by gender to go out.
Starting in April, males in the country are required to leave home on Tuesday, Thursday and Saturday while females can go out on Monday, Wednesday and Friday every week. No one is allowed to go out on Sundays. To further prevent the spread of COVID-19, citizens are able to leave their homes for only two hours at a time. But according to the Guardian, the restriction measures do not apply to civil servants or her important staff who are battling against the novel coronavirus on the frontline.
Colombia
ID numbers are unique identification tools for individuals, but they may also be used to decide when people can go out in Colombia during the novel coronavirus epidemic. According to the BBC, people in some Colombian towns are allowed to be outside based on the last digit (数字) of their national ID number. For example, in northwest-central Colombia, Barrancabermeja, people with an ID number ending in zero, four or seven are allowed to leave the house on Monday, while those with an ID number ending in one, five or eight can go outside on Tuesday.
France
Though outdoor exercise is a good way to keep healthy, it can sometimes cause too many people to gather in one place. In order to prevent the spread of COVID-19, Paris has forbidden all outdoor exercise between 10 am and 7 pm. Outside of this time span, people are allowed to exercise individually as long as it’s for less than an hour and within one kilometer of their home. If people break the rule, they will face fines of between €135 ( about 1,040 yuan) and €375.
