When seeing the doctor, you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance (安想) that all will be well. In such cases the doctor may prescribe a placebo.

    A placebo is a sugar pill, a harmless shot, or an empty capsule. The patient thinks it is medicine and begins to get better. How does this happen?

    The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.

    Placebos don't always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has lots of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.

    A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they'll also show a bad reaction to the placebo. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it.

    The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo.

    Skateboarding is an action sport which includes riding and performing tricks using a skateboard, as well as an activity for fun, an art form, an entertainment industry job, and a method of transportation. In 2016, it was announced that skateboarding will be represented at the 2020 Summer Olympics in Tokyo, Japan.

    There are various theories about the origins of Skateboarding, but it is generally held that the sport began in the 1940s on the west coast of the USA when metal wheels were attached to a narrow wooden board. In the 1950s, plastic replaced metal as the material of choice for the wheels, and the first "Roller Surfboard" become commercially available, which in turn developed into the skateboard that we know today. The sport was a big hit with the younger generation and grew in global popularity in the 1980s and 1990s. Since the late 1990s, skateboarding has become an important part of street culture.

    However, skateboarding has raised heated discussions in areas where the activity, although legal (合法的), has damaged stone works, steps, benches, and parks. Certain cities oppose the building of skate parks in their neighborhoods, for fear of increased crime (犯罪) and drugs in the area. The disagreement between the old image of skateboarding and a newer one is quite obvious: magazines such as Thrasher describe skateboarding as dirty, and still firmly tied to punk (朋克), while other publications, Transworld Skateboarding as an example, paint a more different and controlled picture of skateboarding. As more professional skaters use hip hop, or hard rock music in their videos, many urban youths, hip-hop fans and hard rock fans are also drawn to skateboarding, weakening the sport's punk image. Besides, group spirit influences the members of this community. In presentations of skateboarding, the evidence of crime is absent, and no attempt is made to tie extreme sports to any kind of illegal activity.

    The good news is that efforts have been made to improve recognition of the cultural heritage as well as positive effects of skateboarding in cities. By raising £790,000, the Long Live Southbank initiative managed to stop the destruction of a forty years old spot in London due to urban planning, a rescuing operation whose effect extends beyond skateboarding. The presence of skateboarders on this public space keeps the area under nearly constant watch and drives homeless people away, increasing the feeling of safety in the area. The activity attracts artists such as photographers and film makers, as well as a significant number of tourists, which in turn drives economic activity in the neighborhood.

    In early February 2019, 51-year-old Rainer Schimpf and his team set out to film South Africa's Sardine Run off the coast of Point Elizabeth Sardine Run, the annual migration(迁徙)of billions of sardines (a small sea fish), is a big draw for large predators, especially the dolphin and whale. Predators are animals that kill and eat other animals. In an attempt to obtain the best images of the incredible natural phenomenon, Rainer dived into the middle of a spinning ball of fish. Suddenly the sea moved around violently, and the experienced diver and his photographer Heinz Toperczer, who was filming from the boat, instantly realized something strange was going on. Suddenly dolphins shot out of the water, a white spray came out and then a whale appeared and grasped Rainer

    While Toperczer was filming the terrifying turn of events with his video camera, Rainer, who was trapped had first and engulfed(吞噬)in darkness inside the whales mouth, was trying to survive. Nothing can actually prepare you for the event when you end up inside the pure instinct(本能), "the diver told Barcroft TV. "Knowing in the whale's mouth, I tried to control my fear. But I was convinced that it was going to dive down and release me much deeper in the ocean."

    "The whale quickly realized he was no sardine! As the whale turned sideways, he opened his mouth slightly to release me, and I was washed out, together with what felt like tons of water, of his mouth," recalled Rainer. Though the entire incident lasted just 1.8 seconds, it felt like a year to Rainer.

    Still holding his underwater camera in his hand, the diver swam to his boat, where he was quickly rescued by the members of the team. The terrible adventure did not disturb Rainer for too long. After checking to ensure he had no injuries, the diver returned to the water to seek out more.

    "Depend on yourself" is what nature says to everyone. Parents can help you. Teachers can help you. Others can help you. But all these only help you to help yourself.

    There have been many great men in history. But many of them were poor in childhood, and had no uncles, aunts or friends to help them. Schools were few and not very good. They could not depend on them for education. They saw how it was, and set to work with all their strength to know something. They worked their own way till they became well­known.

    One of the most famous teachers in England used to tell his pupils, "I can not make worthy men of you, but I can help you make men of yourselves."

    Some young men do not try their best to make themselves valuable to the human beings. They can never gain achievements unless they see their weak­points and change their courses. They are nothing now, and will be nothing as long as they live, unless they accept the advice of their parents and teachers, and depend on their own honest efforts.

    Researchers in Australia have discovered an effective new method to capture the atmospheric carbon dioxide that is damaging our planet and transform it into something solid, making it much easier to store.

    Carbon capture isn't new, but previous methods call for the gas to be compressed into liquid and then injected underground. Widespread usage of that technology has been locked by economic and environmental concerns due to possible leaks. Instead, in a study published in Nature Communications, the group details their sustainable and cost-effective plan for transforming CO₂ into coal.

    This new process involves a liquid metal catalyst(催化剂)that is efficient in conducting electricity. CO₂ gas is dissolved in a container with some liquid. Once electricity charge is introduced, the CO₂ begins to turn into solid pieces of carbon, which can be collected and stored.

    What makes this particularly unique is that the entire process can occur at room temperature. Previous experiments have only shown a gas to solid conversion at extremely high temperature, which made it impossible on a large scale. Now, the researchers are hoping that their work will be used to create even further when it comes to carbon storage.

    In an interesting side benefit, the solid carbon also works as an electrode(焊条), which opens up a world of possibilities. "A side benefit of the process is that the carbon can hold electrical charge, becoming a super battery, so it could potentially be used as a part in future vehicles," explains Dr. Dorna Estrafilzadeh, a researcher. "The process also produces fuel as a by-product, which could also have industrial applications."
