When I found out I was moving to India, it was beyond a nightmare. It was something I couldn't even imagine. The impression I had of India were only based upon a few summer visits to my grandparents, filled with heat, pollution and dirt. Even though I was only six years old, I know this would be a complete change from my comfortable life in Maryland.

    During my first six months in India, my expectations were met almost exactly. I hated my new apartment; I missed my school and friends back in Maryland, and I was sick of all the dirty marketplaces that filled the streets of New Delhi.

    After those six months were over I finally realized that I was going to be in India for a while. I knew that I had to start making the most of my new life. It was then that I became completely involved in my school. My school, the American Embassy School, was filled with international students: Europeans, Australians, Chinese, and Americans just like me. But they all welcomed me with open arms. It was amazing to be among such diverse students, who had such incredible experiences to share.

    Now, when I look back at my time in India, all I can think about is how fortunate I am to have had such a wonderful experience. My move to India not only allowed me to see a completely different side of the world, but I was also able to establish unbreakable bonds with so many interesting and amazing people. Even now, after quite some years, I am still in contact with my closest friends from the American Embassy School. I cannot even imagine what I would be like without having lived in India. I would have missed out on meeting so many extraordinary people, and I would be a completely different person today.

    After a confirmed rabies(狂犬病) case in Parke County, Indiana, experts are urging caution if you find a bat(蝙蝠) in your home or office.

    “If you try to kill a bat, you are more likely to get bitten,” said Joy O'Keefe, assistant professor of biology and director of Indiana State University's Centre for Bat Research, Outreach and Conservation. “Most bats people find in their houses are healthy and are not going to bite them and give them rabies.” But they could be a federally endangered species, such as the Indiana Bat, which is found in this area.

    So if you spot a bat in your home or office, don't kill it or touch it with bare hands, O'Keefe said. Instead, put on a pair of heavy gloves and gently move it into a box or bucket. Once contained, the bat can be removed outside.

    “If it's a healthy bat, it'll fly away eventually,” O'Keefe said. “If it doesn't move or seem to be healthy, you can take it to the health department to be tested.”

    This is the time of year when bats move from their summer resting sites to their winter resting sites, O'Keefe said.

    “We get calls every year during the first month of school year from people finding bats in the university's buildings,” said O'Keefe.

    Bats are a great help to people, as every night they can eat up to their entire body weight of insects. Bats, however, are facing great threats from epidemics(流行性疾病), habitat destruction and other things.

    “The best way the average person can help bats is by understanding them and by telling other people how awesome bats are and what bats do for us,” O' Keefe said. “Hopefully, it will make people think that if there's a bat in their house, they should try to get it out but not kill it. That would be really positive for bats—to not have people be one of their major threats.”

A new study reveals that pigeons (鸽子) can tackle some problems just like artificial intelligence, enabling them to solve difficult tasks that might challenge humans. Previous research has theorized that pigeons employ a problem-solving strategy, involving a trial-and- error approach, which is similar to the approach used in AI models but differs from humans' reliance on selective attention and rule use. To examine it, Brandon Turner, a psychology professor at the Ohio State University, and his colleagues conducted the new study. 

In the study, the pigeons were presented with various visual images, including lines of different widths and angles, and different types of rings. The pigeons had to peck (啄) a button on the right or left to indicate the category to which the image belonged. If they got it correct, they received food; if they were wrong, they received nothing. Results showed that, through trial and error, the pigeons improved their accuracy in categorization tasks, increasing their correct choices from about 55% to 95%. 

Researchers believed pigeons used associative learning, which is linking two phenomena with each other. For example, it is easy to understand the link. between "water" and "wet". "Associative learning is frequently assumed to be far too primitive to. explain complex visual categorization like what we saw the pigeons do," Turner said. But that's exactly what the researchers found. 

The researchers' AI model tackled the same tasks using just the two simple mechanisms that pigeons were assumed to use: associative learning and error correction. And, like the pigeons, the AI model learned to make the right predictions to significantly increase the number of correct answers. For humans, the challenge when given tasks like those given to pigeons is that they would try to come up with rules that could make the task easier. But in this case, there were no rules, which upsets humans. 

What's interesting, though, is that pigeons use this method of learning that is very similar to AI designed by humans, Turner said. "We celebrate how smart we are that we designed artificial intelligence: at the same time, we regard pigeons as not clever animals," he said.
