1 . Imagine driving down a country road past a huge, open field where goats are eating grass. Suddenly a truck breaks down and makes a loud noise. Just as suddenly, the goats fall to the ground.
A few moments pass. The goats are back on their feet. What just happened? Well, the goats were very frightened and dropped to the ground, but not all goats act like this. There is only one kind of goat that behaves this way when it is surprised. It is called a Tennessee Fainting Goat.
In the 1800s, a farmer arrived in Marshall County, Tennessee, with a few goats and a cow. People say he came from Nova Scotia, Canada. Since the man did not talk much, no one knew where he got these goats. When he left, he took the cow, but he sold the goats.
The behavior of one of the goats was different from most others. Being frightened caused the goat’s body to go stiff and sometimes fall over. No one had seen goats do this before. They began to call this new goat a Tennessee Fainting Goat.
This special kind of goat does not actually faint. They just look like they do. The fainting goats stay awake. The baby goats, however, usually do fall over, but the good thing is that they do not have far to fall. Some older ones learn to stand near something like a fence or a tree, just in case they are frightened.
Now there are about three thousand fainting goats in the United States. People enjoy raising them, because goats of this kind are gentle, smart, and playful. They just get scared stiff now and then. The moment of stiffness only lasts about ten or fifteen seconds. Then the goats walk and act like any other goat.

2 . The structure of DNA plays an important role in medicine and biology. But you may not know that its founder is a female scientist and goes through a lot on her way to make scientific research. Rosalind Franklin was born in London, England on July 25, 1920. On April 16, 1958, at age 38, she died from cancer. Franklin was responsible for much of the research and discovery work that led to the understanding of the structure of DNA.
Franklin was interested in science and attended one of the few girls' schools in London that taught physics and chemistry. When she was 15, she decided to become a scientist. Her father was decidedly against higher education for women and wanted her to be a social worker. Franklin's aunt decided to support her and she agreed to pay for her full schooling. Within weeks, Franklin's aunt got her mother to support her going to college also. Months later, Franklin's aunt and mother got her father to agree with it. Franklin was very excited that she was going to college and did a good job in her study.
After her graduation from college, Franklin started her research on DNA. However, there were so many quarrels in her life because Franklin and her research partner did not get along. Franklin and her partner's arguments set them back on the study of DNA quite a bit. At the time they were working against another pair to find the story of DNA. Because of Franklin and her partner's fights, another pair found the structure of DNA first and won the Nobel Prize for it four years after Franklin died. Many scientists felt sorry for her early death and thought that the winners had stolen her research about DNA.

3 . At Aizo Chuo Hospital in Japan, employees greet newcomers, guide patients to and from the surgery area, and print out maps of the hospital for confused visitors. They don’t take lunch breaks or even get paid. Why? They’re robots!
Robots have long worked in factories, helping to build cars and electronic appliances. But today’s robots don’t just do the jobs of people－they actually look and act a lot like people.
Kansei, a robot from Japan, has a plastic face covering 19 movable parts. The robot can make 36 facial expressions in response to different words. Kansei shakes in fear at the word “war” and smiles when it hears the word “dinner”.
Researchers in Europe are going even further with iCub, a “baby” robot. They are teaching it to speak and hold conversations.
The ability to interact is crucial for robots that will one day work closely with humans, says robotics professor ChrisAtkeson. “This will require robots to understand what you say and how you are feeling and respond with appropriate emotions,” he told WR News.
Japanese scientist Minoru Asada agrees. He is building a robot called CB2 that acts like a real baby. “Right now, it only goes, ̒Ah, ah. ̓ But as we develop its learning function, it will start saying more complex sentences and moving on its own,” Asada says. “Next-generation robots need to be able to learn and develop by themselves.”
Intelligent robot will become more important in the future, as populations age and the number of human workers declines in many countries. “We’re going to have many more old people and not enough young people to care for them,” says robot researcher Matthew Mason. “Technology can help the old people live at home longer, instead of going to nursing homes.”

4 . Tears well up in people's eyes for a lot of reasons. A teardrop running down the cheek is the ultimate symbol of sadness, but people may also cry because they just cut an onion, or maybe they're trying to blink out an eyelash.
For the most part, tears help maintain healthy eyes. When you blink, basal (基底的) tears clean and smooth the eyes, which helps you to see clearly, according to the American Academy of Ophthalmology. Moreover, reflex (反射性的) tears, or those that happen unconsciously, help clear the eyes of irritants (刺激物), including dust and the gas that's produced when a knife slices a raw onion, said Andre Silva, a doctoral student of psychology at the University of Minho in Portugal.
Emotions can also bring about tears in humans. These emotional tears can serve as a means of nonverbal communication. Silva said, “Babies cry to signal to their mothers that something's up. It's a pure attention call. Some people think that babies are capable of controlling adults by crying, but that idea is false and misleading, as a baby is not conscious of being tricky: In a way, we can consider these tears as being somewhere between basal tears and emotional tears.”
As people grow older, they begin to use their tears to express emotions, such as happiness or sadness. These tears may promote compassion and empathy in others. But beware of people who may use their tears to control others. “Some sensitive people may be easily controlled through the crying of others, and may easily shed tears that can also be used by others to control them,” he said.
So, emotional tears have both advantages and disadvantages. “They are a powerful communication device and a powerful manipulative (操纵别人的) device,” Silva said. Crying also makes it hard for some people to mask their feelings when they're in the middle of an extreme emotional state.

5 . American billionaire Elon Musk has demonstrated a technology designed to use a computer chip inside the head to control the brain. During a video demonstration on Friday, Musk provided details about the system, called Neuralink.
Musk says he hopes the technology can be used to treat neural disorders and help spinal injury victims regain body movement. Musk also believes the system could be used in the future to improve intelligence to help humans keep up with supercomputers and artificial intelligence (AI) technology.
During the show, Musk showed off a model of the Neuralink device. It is about 23 millimeters wide. It is designed to be implanted into a person's skull. Small wires would connect the device directly to the brain.
The Neuralink system is currently being tested in pigs, with plans to seek government approval for human testing sometime in the future.
A pig named Gertrude was also shown during the show. Musk explained that Gertrude had a Neuralink chip inside its head. The device is meant to record nerve activity in the pig's nose and mouth.
Musk said the company had three pigs, each with two chips. He described the animals as "healthy, happy and indistinguishable from a normal pig." Musk said the company was able to predict with "high accuracy" a pig's leg movement on a running machine using data from the chip.
Musk noted that Neuralink first wants to use the device on people with severe spinal cord injuries to help them talk and move using their brain waves. He said he is hopeful that, in the long term, those people could regain "full-body motion."
Some neuroscientists not linked to the company said the presentation suggested Neuralink had made great progress with the technology. However, they warned that many more studies will be needed to test the long-term success of such devices.
