Eldon Musk, the entrepreneur and CEO of Tesla and Space X, may have a little more time on his hands, as he's leaving his position on the board of the Open AI, according to a blog post.

    The departure is likely the result of Tesla's moving into the field of Artificial Intelligence (AI), which he said in 2017 would be the “best in the world” and would even be able to “predict your destination.” Musk will continue to “donate and advise the organization,” Open AI said in a blog post on Feb. 20, adding that “As Tesla continues to become more focused on AI, this will avoid a potential future conflict for Eldon.”

    Musk and Y Combiner CEO Sam Altman co-founded the nonprofit enterprise in December 2015, its mission is to develop safe artificial general intelligence and ensure those developments are made public. Open AI researchers published a paper on the site ArXiv.org, detailing the possible secure threats that come with “malicious” AI. In fact, Musk has heard the “evil AI” alarm several times. On Aug. 11, 2017, he warned that artificial intelligence poses a bigger threat to humanity, and he told a gathering of state governors that the government needs to regulate AI before robots start “killing people.”

    Musk's departure from the Open AI board could mean big things for Tesla. As Eton Goodbye, a financial reporter, noted on Futurism, the move “could signal that Tesla is more deeply committed to their own AI projects than we thought.” He added, “Those who have had their ears to any rumors (谣言) that Tesla is ready to deliver vehicles capable of Level 5 autonomy could take this new Open AI development as a sign that the company is inching closer to that unapproachable goal.” No company has reached that level of autonomy, which means that a driverless car could navigate any road under any conditions and that all the human “driver” would need to do is to input a destination.

    As any plane passenger will confirm, a crying baby is almost impossible to ignore, no matter how hard you try. Now scientists believe they may have worked out why. A baby's cry pulls at the heartstrings(扣人心弦) in a way while other cries don't, researchers found.

    Researchers found that a baby's cry can trigger unique emotional responses in the brain, making it impossible for us to ignore them—whether we are parents or not. Other types of cries, including calls of animals in great pain, fail to get the same response—suggesting the brain is programmed to respond specifically to a baby' cry.

    A team of Oxford University scientists scanned the brains of 28 men and women as they listened to a variety of calls and cries. After 100 milliseconds—roughly the time to blink(眨眼)—two parts of the brain that respond to emotion lit up. Their response to a baby's cry was particularly strong. The response was seen in both men and women—even if they had no children.

    Researcher Dr Christine Parsons said, “You might read that men should just notice a baby and step over it and not see it, but it's not true. There is a special processing in men and women, which makes sense from an evolutionary view that both men and women would be responding to these cries.” The study was in people who were not parents, yet they are all responding at 100ms to these particular cries, so this might be a fundamental response present in all of us regardless of parental status.

    Fellow researcher Katie Young said it may take a bit longer for someone to recognize their own child's cries because they need to do more “fine-grained analysis”. The team had previously found that our reactions speed up when we hear a baby crying. Adults performed better on computer games when they heard the sound of a baby crying than after they heard recordings of adults crying.

    "An apple a day keeps the doctor away." Similarly, if we drink a little more water every day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fiber, without giving us too much fat and sugar. But why is water important?

The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.

    Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems start as a result of dehydration (脱水)-—a lack of water in the body. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stage of dehydration. In fact, we are advised to drink water before we feel thirsty.

    These doctors think that health problems such as headaches, high blood pressure and asthma (哮喘) could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.

How Did Poetry Begin?

Poems can make you feel emotions, like anger or sadness, depending on the words and how they are put together. That is the 1 of poetry. 

Poetry 2 even before humans knew how to read and write, dating back to around 3000 BCE. Some of the earliest poetry was 

3 or sung, and was used as a way to record and pass down historical and religious stories and cultural traditions from one generation to the next. Since writing was not practised then, certain sounds and rhymes were used to make these stories 4 and therefore, memorable. 

There are 5 three types of ancient poetry. The first was an epic(史诗) or long narrative(叙事的) poetry usually about a 6

event. The second type was lyric(抒情的) poetry or poetry that 7

personal feelings. Finally there was drama or stories written in verse and usually 8 like Greek tragedies and Shakespeare's plays. 

The invention of the printing press(印刷机) in the 15th century brought poetry to the common people. This was followed by several major literary periods, during which poetry 9 dramatic changes. They started with Europe's Renaissance period from the 14th to the 16th century, which first helped poetry and poets like Shakespeare and Sir Walter Raleigh become popular. 

The Romantic period saw 10 poems that expressed a poet's joys, hopes, and sorrows in a conversational tone. Then came the Victorian era, which saw the 11 of structured poems and the birth of modern "12 verse" poetry. American poet Walt Whitman's Leaves of Grass is 13 to be the first example of free verse poetry. 

Modern poetry is a 14 of all of these styles. We still see rhymes in children's poems and in the popular African-American styles of hip hop and rap music, which are a 15 of rhymed poetry put to a musical beat. 

For many students who desire to move around but not far freely, one of the most common vehicles is the bicycle. For such a seemingly simple invention, its story is not that simple.

Most historians trace its origin back to 1817, when a German nobleman named Karl von Drais invented a wooden, two-wheeled machine that riders moved forward with their feet. His invention became popular in both England and France, where it eventually became known as the velocipede. Unfortunately, it was eventually banned as a danger to pedestrians and was rarely seen after the early 1820s.

Things were quiet for several decades until the bicycle development took off in the 1860s. An important milestone happened in Paris in 1863 when pedals (踏板) were added to the front axle (轴) . This occurred in Pierre Michaux's workshop but it's unclear whether he or his employee, Pierre Lallement, should be given credit for the innovation. Lallement moved to the United States, where he obtained a patent for "improvements in velocipedes" in 1866. These new machines proved to be popular, and the name "bicycle" had come into use by 1869. However, many people referred to them as "bone shakers", which described their clunky ride due to a heavy wooden frame and steel wheels.

In the 1870s, "high wheelers" or "penny-farthings" became popular. However, with a large front wheel and a much smaller rear wheel, they could be dangerous, if riders had to stop suddenly, as they would "take a header" when their momentum (动量) carried them over the front wheel onto their heads. Eventually, English inventor John Kemp Starley designed a "safety bicycle" with two same small wheels, a chain drive, and a set of gears. With tires added in and brake (刹车) systems bettered in the following decades, bicycle production had skyrocketed to over one million bicycles by 1899.

Mass production of bicycles increased their popularity greatly, since they became affordable for the average person. Over the course of the 20th century, manufacturers continued to improve the features and design of bicycles as new technologies appeared.
