Nobody likes doing the dishes, but it turns out that doing this daily task might pay off in an unexpected way. According to a new study published in the Journal of Pediatrics, washing dishes by hand instead of using a dishwasher might prevent the development of allergies.

    Researchers in Sweden surveyed the parents of 1,029 children ages 7 and 8. They discovered that children whose families hand-washed the dishes instead of using a machine were less likely to have allergies.

    Earlier research has shown that dishes washed by machine are cleaner than those washed by hand. So why would kids who eat off slightly dirtier plates be better off when we talk about preventing allergies? One explanation is based on a theory known as the "hygiene hypothesis (卫生假说)," which says the reason why kids develop allergies is that their surroundings are actually too clean.

    Your immune (免疫) system keeps you healthy by fighting germs (病菌) like bacteria and viruses. But when you have allergies, it overreacts and tries to fight ordinary things like pollen (花粉) or certain foods.

    Being exposed to germs, particularly early in life, is good training for the immune system, says the lead author of the study, Dr. Bill Hesselmar of Queen Silvia Hospital in Sweden. "You excite the immune system in various ways and it becomes tolerant."

    This study shows that while using the dishwasher might be easier, the old-fashioned method of cleaning up could be better for your health.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow (乌鸦) landed on their window.

    The father asked his son, “What is this?”

    The son replied, “It is a crow.”

    After a few minutes, the father asked his son for the second time, “What is this?”

    The son said, “Father, I told you just now. It's a crow. ”

    After a little while, the father again asked his son the same question for the third time, “What is this?”

    This time, the son said to his father in a low and cold tone, “It's a crow, a crow.”

    After a moment, the father again asked his son for the fourth time, “What is this?”

    This time the son shouted at his father, “Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW'. Are you not able to understand this?”

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page. The following words were written in it.

    Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feet angry, but instead felt affection for my son.

    So...

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. Be considerate to your parents.

    A Japanese company, Next Technology, has created a robot dog that can tell you how bad your feet smell, by using a powerful sensor fixed in its nose. If you feet don't have a bad smell. Hana-chan will happily wag its tail, if it's exposed to feet that are mildly smelly, it'll start to bark, and if they give off an extremely bad smell, it'll just fall over like the smell caused it to faint(昏倒).

    Foot odor (脚臭) is a big deal in Japan, where it's a custom for people to take off their shoes whenever they enter someone's home. In fact, exposing others to bodily odors can be considered annoyance in Japan. Some of the most brilliant minds in the country's tech industry have been trying to solve this problem. Last year, Thanko started selling axmpit (腋窝) fans designed to keep people's armpits nice and dry Now, we have Hana-chan.

    The robot dog has a special sensor for a nose, and can tell you if your feet smell just by sniffing them for a few seconds. According to some media reports, Hana-chan can help solve the problem of extremely smelly feet by spraying them with air freshener, but it's unclear whether this feature comes built-in, or if you'll have to pay extra for it.

    According to researchers at NextTechnology, the idea for Hana-chan was inspired by a person who desperately wanted some way to know if his feet smelled. "He told us his daughter had said his feet were smelly, " NextTechnology's Kimika Tsuji said. “But he didn't want to know how bad the odor was because he would feel hurt. That's why we developed this cute robot. "

    You may be able to make Hana-chan faint with your smelly feet, but it can have the same effect on budget-conscious people. NextTechnology plans to start selling the feet-smelling robot dog for ￥100, 000 ($9, 280) next May.

    The Poetry Foundation, recently named American poet Jack Prelutsky as the nation's first children's poet laureate (桂冠诗人). The group created the award as a way to increase children's love of poetry.

    As children's poet laureate, Jack Prelutsky will give two public readings in the next two years. He will also advise the Poetry Foundation about children's literature and take part in projects concerning children and poetry.

    Jack Prelutsky has been writing poetry for children for over forty years. He has written more than thirty five books of poems. His first book was called A Gopher in the Garden. It was published in 1967. His latest is called Behold the Bold Umbrellaphant and Other Poems.

    Jack Prelutsky is well known for creating new words by combining two words to create a new kind of creature. For example, he combined "radish" with "shark" to get "radishark". "Lion" and "broccoli" became "broccolion". He also created "umbrellaphant"， a mixture of the words "umbrella" and "elephant".

    Jack Prelutsky says that children like his poems because he writes about things they care about. Poetry researchers say that Jack Prelutsky's poems recognize children's feelings. An example of this is the poem My Sister Is a Werewolf which is about how it feels to be different.

    Jack Prelutsky also writes poems about American holidays. His poem It's Halloween is a very famous one about the holiday celebrated at the end of October.

In many ways, Providence Mount St. Vincent in Seattle is a typical senior living community. It is home to about 400 elderly people and provides them with different types of assistance. However, it is also the Inter-generational Learning Center—a preschool where children and seniors have the chance to bond（结成友好的关系）.

    Established in 1991, the ILC's purpose is to allow kids to learn about acceptance while also being nurtured. It also aims to help seniors develop a greater sense of self-worth and strengthen social interactions. Babies to prekindergarten-aged children are placed into six different classes at the ILC. The kids attend art and music classes, as well as story time and exercise time with the seniors. Marie Hoover, ILC director, said that interacting with the seniors has proven beneficial for the young ones, making them more open-minded.

    “For the ILC children, interacting with the residents is simply part of their day-to-day life here and the way aging is 'normalized', which may be the most important benefit they receive,” Hoover said.“ I've had parents call me years after their children have graduated from our program to let me know about some incidents when their child was the first to warmly greet someone who happened to be in a wheelchair.”

    As for the seniors, they're delighted by the companionship the children provide. The children bring so much energy and joy to our residents. Many of residents are widows or widowers and can become lonely. Their adult children may still be working, so they may not get to see them as often as they would like. Having the children stay with the old makes our residents feel they are still part of a community. The young and the old connect and learn from one another at this unique facility.

    Machines equipped with artificial intelligence (AI) have performed better than human beings in a high-level test of reading comprehension. Two natural language processing tools received higher test scores than humans in recent exams.

    One of the tools is a product of the American software maker Microsoft. The other was created by the Chinese online seller Alibaba Group. The company said that a deep-learning model developed by its Institute of Data Science of Technologies was the first to beat a human score in the reading comprehension test.

    The test is called the Stanford Question Answering Dataset. It was developed by researchers at Stanford University in California. It has over 100,000 questions and answers. They are based on information found in over 500 stories from the Wikipedia website. The answers to all the questions come from the reading material.

    The AI-powered machines were tested on whether they could provide exact answers to the questions after processing large amounts of information.

    Alibaba said its deep neural (神经的) network model received an “Exact Match” score of 82.44 on the Stanford test. Microsoft reported that a team at Microsoft Research Asia had a score of 82.65. It said the human score on the same questions and answers was 82.304. Many research organizations also appeared on the list—all with scores below 82.

    Alibaba said it has already used its reading comprehension model in different parts of its business. For example, the company is using machines to answer many incoming telephone calls from customers. The company says in the future, the technology could enable machines to guide visitors through museums or provide advice to medical patients.

    Microsoft noted that, overall, people are still much better than machines at understanding the complexity and nuances (细微差别) of language.
