The United States is a country of immigrants. It is a place where people from all over the world come to build a better life. Some immigrants bring their families. Some bring a few of their favorite things. Others come alone with nothing but determination. One thing that every immigrant brings with them is their culture.

    American immigration began in 1607 with the colony (殖民地) of Jamestown. In 1620, another group of people left England to build a settlement in America. They wanted to go to a place where they could practice their religion freely. Then many more people left their homes in Europe to build a better life in America. Many also came to America from Africa. By 1770, more than two million people had moved to America. Later on, more people came to the United States than ever before.

    In cities all over America, you can see different cultures that formed this country. Many things that you may think of as being “American” are actually from a foreign culture. Some of the best examples of this are the foods people eat. Pizza and spaghetti are foods that all Americans know and love. But both of them are from Italy. Baseball is an all-American sport. But the hot dogs that people eat during the game are a type of food that was brought to America by German immigrants.

    Over time, pizza and hot dogs have become a part of what is considered to be American food. In the same way, different groups of people have come together to define what an American is. An American can be a person of any background. An American can be of any faith. An American can be of any skin color. They can speak English clearly. They can speak English with an accent. Each new immigrant adds something new to American culture. It will keep changing as more people come to this country.

    The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

    ⒈How many times did you brush your teeth yesterday?

    Finding: A full 33% of seniors brush their teeth only once a day.

    Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

    ⒉How many times did you wash your hands or bathe yesterday?

Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number which doctors recommend.

    Step: We touch our faces around 3,000 times a day-often inviting germs（病菌）to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

    ⒊How often do you think about fighting germs?

    Finding: Seniors are not fighting germs as well as they should.

    Step: Do you know it is not your toilet but your kitchen sponge（海绵）that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

    A mother goat is able to pick out her own baby from its voice alone by the time the kid is just five days old.

    Researchers from University of London played kids' bleats to female goats and studied their responses. They were surprised to find that the animals were able to pick out their own kids' voices.

    “A mother and the kid rely a lot on smell to recognize one another and, in the wild, during the first week of their lives, the animals hide in grass and don't call much. It's a strategy they use to avoid enemies,” Dr Elodie Briefer, who led the research, explained to BBC News. “The mother call to the kids when she want them to come and feed, so we expected that kids would recognize the mothers' voices.” In fact, this was the case for deer, which also use this hiding strategy, although they do not belong to the same family of species as goats.

    She and her team recorded and played back young kids' calls to the female goats and recorded their responses. She explained, “Even when the calls came from kids that are five to six days old, we could see the mothers responding more to the voices of their own babies.” Hearing the voice of their own kids, the females would look towards the speaker that the sound was coming from, moving around and calling in response.

    The scientists say that understanding how goats behave and communicate is very important. “This helps us understand just how smart these animals are,” said Dr. Briefer. “Farmers might be able to change their way to raise goats considering this natural behaviour.”

Gottfried Wilhelm von Liebniz was a philosopher and mathematician in search of a model. In the late 1600s Leibniz decided there was a need for a new, purer arithmetic than our common decimal (十进制) system. He got his inspiration from the 5000-year-old book that is at the heart of Chinese philosophy: the I-Ching, or Book of Changes.

This ancient text was such an influence on Liebniz that he titled his article on the new arithmetic "Explanation of a new arithmetic and the ancient Chinese figure of Fu X". Fu Xi was the legendary first author of the I-Ching. The arithmetic that Liebniz described was binary (二进制) code, which is used in almost every modern computer, from iPhones to China's own Tihane-2 supercomputer.

To figure out what Liebniz learned in the I-Ching, we need to understand something that most of us have taken for granted. When we listen to an MP3, look at a digital photo or watch the latest TV drama, we are experiencing a digital representation of reality. That representation is basically just a string of binary signals that are commonly known as 1s and 0s. What Liebniz's gained from the book was that even the most complex reality could be represented in the binary form as 1s and 0s.

In the philosophy of the I-Ching, reality is not entirely real. It is something more like a dream. This dream of reality arises from the binaries of Yin and Yang, as they play out countless combinations, practically everything in the universe. It's not surprising then, from the l-Ching's perspective, that anything in the dream of reality can be represented in a string of 1s and 0s, processed by a computer.

The I-Ching was far more ambitious than the current practical applications of binary code. It is claimed that the I-Ching represents nothing less than the basic situation of human life itself. As a system for predicting the future, the I-Ching might disappoint, but as a way of questioning your own unconscious mind, it can be remarkably useful.

The I-Ching's teachings also contain warnings about our digital revolution. Binary code, powered by modern computers, has an amazing capacity to represent reality. However, the ancient authors of the I-Ching might have understood its potential-and its dangers-even better than we now do.

So when scientific thinkers ask whether computers can create "virtual realities" or "artificial intelligence", they are missing the point. Of course, we can create ever deeper and more complex layers of the dream of reality. The real question is, can we wake up from the dream we're in already?

As people are becoming more socially conscious about where their food comes from and how it impacts the planet, they are choosing animal-free plant-based options. Cow-free meat has been around for quite some time and the popularity of brands of the cultivated meat is rising. While there are a large number of plant-based milk substitutes, none of them have the same taste of cow's milk. Now, a food-tech company created real dairy products without harming a single cow or the planet.

The company stresses that their product produced in the lab is not a milk substitute but rather is the real deal. And it is very healthy. The company also says that the lab-produced milk tastes identical to the real thing and they hope to eventually replace cows by creating every dairy product sold. They expect to roll out plant-based cheese and yogurt in addition to milk. “Our company was founded with the mission to stop using animals to produce -our food because, as dairy lovers, we realize that giving up on milk is not an option,” John said. “But today's milk comes with an unreasonable price tag. The dairy industry is destructive to our planet, our health, and our animals, and is simply not sustainable anymore.”

The environmental price tag of dairy farming is way too high. According to the World Wildlife Fund, dairy cows add a huge amount of greenhouse gases to the atmosphere and-contribute to global warming and climate change as well as pollute the air around them. Dairy operations consume large amounts of water and run-off of manure and fertilizers from these farms get into local waterways. The production uses only 5 percent of the resources and produces only 1 percent of the waste of producing cow's milk according to the company. And they accomplish this by being 100 percent cruelty-free unlike dairy farms.
