【推荐2】At five, I started getting ear infections. When I got a third infection, my parents couldn’t afford the treatment. I went deaf in my fight ear and was left with 20 percent hearing in my left at last. My doctors predicted that I would be thoroughly deaf but I’m not.

There was always music on in my house in my childhood. My dad was a DJ, so he played different kinds of music home and abroad. For my 18^th birthday, my dad asked me to deejay at the restaurant he owned. After doing that for a few weeks, I desired to learn more. I e-mailed DJ Shiftee, a distinguished New York City DJ: “ I know you like a challenge. How about teaching a deaf person to deejay?” He wrote back, “Challenge accepted.” He tutored me, helping me develop correct technique. I practiced four hours a day.

Now when I’m performing, muscle memory takes over. When I started, I wouldn’t tell the club managers that I was deaf. I would just shop up, introduce myself, and start playing music. They were always so astonished to hear I was a deaf DJ. Sometimes I would bring doctor’s notes to prove it. It was a comfort that they were giving me opportunities to perform because I was brilliant, not out of sympathy. Eventually people started calling me “ that deaf DJ”, and the name stuck.

What fascinates me most about deejaying is the creativity. I use software that turns the music into lines of color on a computer screen. I’m visually hearing the music. That is, cover your ears, and you’re able to hear the music in a different way. Music is not all about hearing. I play all sorts of get- togethers now. I also go to elementary schools for the deaf and talk to the students about motivation and believing in themselves. I’m big on talking to the parents. I tell them, “ My advice to you is let your kids chase their dreams. I’m a deaf DJ, so why not?”

Grilffith Taylor—an Australian geologist, had discovered a blood red steam pouring out of the ice cascades（瀑布）of Talor Glacier! Popularly known as the Blood Falls, scientists had not been able to find the reason behind the blood red liquid flowing through the ice---until recently. The mystery of the Blood Falls had finally been solved.

When these falls were first discovered, scientists had believed that the red colour came from a large amount of red algae（海藻）concentrated in the water. Red algae contain a pigment（色素）which reflects red light, making the algae appear red.

This theory made sense, until it was later found that algae do not play a part in the red color of the flowing liquid at all. What really causes Talor Glacier’s waters appear blood red, is the presence of iron oxide in the liquid. The waters of the blood falls are rich in salt and iron content, and when this water comes in contact with the air, it turns red—just like rust! The water in these falls is often referred to as “brine” by scientists because of the high salt content in the water.

This reasoning behind the red colors of the falls was found back in 2003. However, the entire mystery had not yet been solved. How is it then, that the Blood Falls are not frozen?

Researchers at the University of Colorado and University of Alaska found that inside the glacier, there was a network of channels and reservoirs that move the water around. Salt water has a lower freezing temperature. In addition, when any substance undergoes a change in state, it gives off heat. Therefore, the brine actually warm itself up while it’s freezing! How this works, is that when the brine is flowing through the Talor Glacier, some of it does freeze. As a result of changing state from liquid to ice, the brine gives off heat. This heat is enough to keep the rest of the rest of the brine in liquid form, which is why it flows out of the glacier.

Incredible new chemistry facts found, any mystery solved!

In August, it is very hot and wet in the southern part of the United States.People there have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.

The weather can also influence intelligence. For example, in a 2018 report by scientists, IQs of a group of students were very high when a very strong wind came; but after the strong wind, their IQs were 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August)．

Weather also has a strong influence on people’s feelings. Winter may be a bad time for thin people. They usually feel cold during these months.They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger.

Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on low­pressure days. There is “good weather” for work and health. People feel best at a temperature of about 18 ℃.

Are you feeling sad, tired, forgetful, or unhappy today? It may be the problem of weather.

Recently, China’s Xinhua launched(推出)the world’s first AI news presenters with the Chinese search engine Sogou. The news readers created by machine learning technology are based on two real-life newsmen. One is able to present newscasts in English; the other, in Mandarin Chinese.

Machine learning is used to examine video images and sounds of the two newsmen, which look and sound like real people. Some machine learning experts said the system showed off China’s latest progress in voice recognition, text-to-speech technology and data analysis. But several experts suggested that the term Al does not correctly describe abilities of the robotic news readers.

On social media, many Chinese noted that the AI presenters did not seem real. People blamed them for not being more lifelike. Others wondered about the effects robots might have on employment and workers. Some people argued that only low-level jobs requiring heavy labor will be easily replaced by robots. Others praised the technology as a way for companies to make money from low-cost labor machines.

Some businesses have experimented with similar technology for possible use in news operations. Britain’s BBC recently released a video that used machine learning to make it look like one of its news readers speaking different languages. The London-based company that developed the system says its goal is to “remove the language barrier” for many different kinds of video across the Internet.

Yes, there really is a job where you can get paid to taste ice-cream. Just ask John Harrion, an “Official Taste Tester” for the past 21 years. Testing helps manufacturers to be sure of a product’s quality. During his career Harrison has been responsible for approving large quantities of the sweet ice cream — as well as for developing over 75 flavors (味道).

Some people think that it would be easy to do this job, after all, you just have to like ice cream, right? No — there’s more to the job than that, says Harrison, who has a degree in chemistry. He points out that a dairy or food-science degree would be very useful to someone wanting a career in this “cool” field.

In a typical morning on the job, Harrison tastes and assesses 60 ice-cream samples. He lets the ice cream warm up to about 12℉. Harrison explains, “You get more flavor from warmer ice cream, which is why some kids like to stir it, creating ice-cream soup.”

While the ice cream warms up, Harrison looks over the samples and grades each one on its appearance. “Tasting begins with the eyes,” he explains. He checks to see if the ice cream is attractive and asks himself, “Does the product have the color expected from that flavor?” Next it’s time to taste!

Continuing to think up new ideas, try out new flavors, and test samples from so many kinds of ice cream each day keeps Harrison busy but happy — working at one cool job.
