Fear may be felt in the heart as well as in the head, according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting (收缩) and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain reacts to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said: “Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed. Therefore our hearts can also influence what we see and what we don’t see—and guide whether we see fear.”
To further understand this relationship, the scientists also used a brain scanner (扫描仪) to show how the brain influences the way the heart changes a person’s feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear,” Dr Garfinkel said.
“We hope that by knowing more about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety (焦虑) disorders, and also for those who may be suffering from serious stress disorder.”

【推荐1】①What is the worst disease in the world? Many people might say it is cancer. Cancer will kill about 9.6 million people in the world this year, according to WHO. Scientists have been working to find ways to beat cancer. A lot of progress has been made in this field.
②James P Allison from the US and Japanese researcher Tasuku Honjo discovered a new cancer treatment that helped them win the 2018 Nobel Prize in Medicine in October. The new treatment can help people effectively(有效地)fight cancer cells(细胞). It is hoped that this treatment can be used to treat most cancers in the future.
③This is not the only recent improvement in cancer treatment. In November, the US approved a new cancer drug called Vitrakvi. Instead of being effective only for treating specific types of cancer, this drug can be used to treat 17 different kinds of cancer, USA Today reported.
④Finding cancer as early as possible is the best way to beat it. To check people for cancer, doctors must collect tissue(组织)from a patient’s turmor(肿瘤), Australian scientists developed a simple cancer test that can detect cancer in a patient’s blood. The test takes less than 10 minutes and it is about 90 percent accurate(准确).
⑤With all of these treatments, cancer can be effectively controlled. Honjo believes most kinds of cancer will become treatable by 2050. “Even if we cannot completely eliminate the turmor, we can still live while still having part of a turmor.” Honjo added.

【推荐3】In England, people can go to the nearby hospital to see a doctor when they are ill. The doctor usually asks about their problems or illness, and then he or she will give them a prescription (处方) for some medicine.
Not all people go to see a doctor when they feel sick. For example, when they only have a cold, they don’t go to see their doctors. They only go to the medicine shop to buy some medicine.
When people are badly ill, the doctor will go to their houses. In an emergency (紧急情况) people can call 999 for an ambulance. The ambulance can take them to the hospital very soon. When they are in hospital, their friends or family members can go to see them at a certain time, but they can’t stay long.
Usually people have to pay for the doctors’ prescriptions. And the price is the same for any kind of medicine. But when children, students, old people or people without jobs go to see their doctors, they don’t have to pay for their prescriptions.

【推荐1】Walk or drive to work? Which way is lower in carbon? To be friendly to the environment, you may choose to walk. Have you ever tried to live a low-carbon life through your diet?
A new study from the University of Oxford has looked into the health and environmental influences of 15 foods common in western diets. Among these, plant-based foods included fruits, vegetables, nuts and potatoes. It also studied animal-based foods, including red meat, chicken, milk products, eggs and fish.
According to the study’s lead researcher, Michael Clark, “Choosing better and greener diets is one of the main ways people can improve their health and protect the environment.” That is to say, plant-based diets are much healthier for us and kinder to the environment.
To get this result, researchers compared the influence of eating another portion (一份) of each food with the increased risk of a few illnesses. They also find out the environmental harm for each animal-based food and each plant-based food.
By using this method, the study found that red meats were the most unfriendly foods to the environment. Keeping farm animals produces a large number of methane (甲烷) that keeps 30 times more heat than CO2. As well as making the earth warmer, eating too much red meat is known to increase the risk of a few illnesses, such as heart trouble.
Plant-based diets can give us the same health benefits (好处) in a much greener way. According to the study, without eating or using meat and milk products, global farmland use could be cut down by more than 75% and still feed the world.
Speaking to the Guardian, Tim Benton of Chatham House said, “If we can give peopled reasonable official advice of what a healthy and green diet is, the world and its people would be in a much better place.”

【推荐2】Is the whale the world’s largest fish? No. It looks like a fish, but it is really a mammal(哺乳动物). Then what’s the world’s largest fish? It’s the whale shark(鲸鲨).
Although the whale shark is our biggest fish and lives in the ocean(海洋) around the world, few people have ever heard of it. Scientists have not been studying whale sharks for very long. Much more needs to be learned about them.A whale shark is sometimes called a “ gentle giant(温柔的巨人)”. It likes to be alone and doesn’t care a bit about divers or humans. The biggest whale shark weighs 24, 250 pounds and is nearly 40 feet long. This makes it heavier and longer than a school bus.
Inside its huge mouth are great numbers of very small teeth. To count all of them, you’ll need to do some math. The whale shark’s teeth are arranged in rows. There are between eleven and thirteen rows on each jaw(颌) and around three hundred teeth in each row.
However, the whale shark rarely uses its teeth. It does not chew or bite its food. Large amounts of water are pulled into its mouth and then pushed out through its gills(腮).
For a few months every year, a group of whale sharks comes to the Ningaloo Reef, off Western Australia. This gives scientists a wonderful chance to study the large fish.
Whale sharks do live in the ocean around the world, but no one knows their population. It is possible that our biggest fish may need protecting. It is one of the reasons why scientist continue to learn about these gentle giants.

【推荐3】China’s South-to-North Water Diversion Project (南水北调工程) is a huge project which has three water lines: east, central and west. Each water line is over 1,000 kilometers. The central line is over 1,400 kilometers long. It starts at Danjiangkou and runs through Henan, Hebei, Beijing and Tianjin. On such a long transportation journey, how can we make sure the water is clean and safe?
All year round, the instruments under the water are working for changes of water. If something unusual is found, the staff will take action right away.
The drones (无人机) over the water surface are flying to check the river. They can fly up to 400 meters in height and 5 kilometers in distance. The cameras carried by the drones can provide the water condition of the river. On these facts, people will know whether the water situation is safe or not.
Besides, the water from Danjiangkou needs to go through the “two nets” before entering the riverbed. Almost all the big floating (漂浮) objects on the water are kept off the gates. Then the cleaning robots will work much further against the small ones.
The staff are required to monitor the water quality every day so that every drop of water can meet the safety standard. The central line project includes 5 fixed laboratories, I mobile laboratory, 13 water quality monitoring stations...in Henan, Hebei, Tianjin, and Beijing. They are all working day and night to make people drink clean and safe water.
The primary purpose of the central line is to provide living water for the people along the line. So the water quality is of great importance. With those efforts, the water quality of the central line project meets the Class Ⅱ standard for surface water, Nearly 80 million people along the line get clean water from it since its opening in December, 2014.

【推荐2】You might not think much about where your garbage goes. But now you might want to know. On July 1, Shanghai had a new garbage sorting policy(垃圾分类政策). People there need to put different kinds of garbage into different bins. Other cities in China will do the same soon.
Why is garbage sorting a big problem? It’s because there is too much garbage these days. It is bad for our land, air and water. In fact, we can make use of some garbage again. And first, we need to sort(分类) our garbage. For example, if you put an old battery(电池) into the “harmful waste(有害垃圾)’’ bin, people can use it to make new batteries. But if you don’t, the battery will end up somewhere else. Then, it will be bad for the environment(环境).
Can’t factories sort garbage for us? Yes, they can. But it takes many workers to do this and needs lots of money. If we all sort our own garbage, things will become much easier.
