At 80 years old，scientist Jane Goodall continues to enjoy the joy of discovery.“Trees can communicate with each other，” she said during her Nov.16，2014 China visit to celebrate the 20th anniversary of the China establishment of her youth organization Roots & Shoots，which has grown to more than 600 branches in the country among 150，000 active groups globally.

    Jane Goodall still travels 300 days a year in all around the world and says she absorbs energy from the inspired people she meets in each country.The elderly activist and the youth take inspiration from each other.

    On Nov.16，2014，she visited the project of Roots & Shoots which was set up in Beijing.“She thought our project was great，” says 16－year－old Beijing Experimental High School student Qi Zhengyang，whose group helps protect a wetlands in the suburbs of Beijing.“She said we're doing a good job.She paid attention to us.”

    Jane Goodall plans to continue to set up Roots & Shoots branches as many as possible throughout the world.“I'll go on as long as I can，” she says.“I hope I maintain physical health as long as possible because there's so much to do.” Her aspiration for the organization in China is to expand in rural areas.Most branches are in big cities as Beijing and Shanghai.

    It was publishing her findings about chimpanzees (My Friends the Wild Chimpanzees)  more than half a century ago that made Jane Goodall a household name in the world.She was named United Nations Messenger of Peace in 2002.

    Some of the members in Roots & Shoots realize Goodall is 80 and has already considered who'll lead the movement once she's gone.“It can be all of us，” she says.“A group is stronger than one person.We can do more working together.”

    The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

    A ten-year-old from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

    That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing cold weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids his age would have, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth to Danny's hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old had fallen down on some ice in her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they waited for the ambulance (救护车) to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny, for following up on his hunch!

    Chinese researchers say they have come up with a simple way to find out a person's biological age —how much the body has aged physically – through a urine (尿) test.

    Their findings will help researchers conduct numbers of ageing studies and even predict a person's risk of age-related diseases, according to a paper published in the journal Frontiers in Ageing Neuroscience.

    Another paper by researchers at the Beijing Hospital and the West China Hospital in Chengdu, Sichuan province, said on Tuesday that people aged at different rates due to changes in their genetic make-up and their environment.

    Chronological age – which is based on one's birth date —was not an exact measure of biological age so a more exact method was needed, the team said.

    Ageing is driven by the lifelong gradual accumulation(积累) of a broad variety of molecular (分子) faults in the body's cells. The team said they had identified a matter 8-oxoGsn that indicated increases in oxidative (氧化性) damage in urine as people's bodies aged.

    Cai Jianping, a co-author at the Beijing Hospital, said: “As we age, we suffer increasing oxidative damage and so the levels of oxidative matters increase in our body.” The team tested the levels of 8-oxoGsn in urine samples from 1,228 Chinese people aged two to 90 and concluded the marker helped accurately determine the stage of biological ageing in adults.

    They had previously found that 8-oxoGsn levels also increased with age in the urine of animals such as mice.

    The team has also developed a rapid analysis technique called ultra-high-performance liquid chromatography(层析法), which can process up to 10 urine samples an hour, according to the study.

    When I was nine years old, I loved to go fishing with my dad. But the only thing that wasn't very fun about it was that he could catch many fish while I couldn't catch anything. I usually got pretty upset and kept asking him why. He always answered, "Son, if you want to catch a fish, you have to think like a fish." I remember being even more upset then because, "I'm not a fish!" I didn't know how to think like a fish. Besides, I reasoned, how could what I think influence what a fish does?

    As I got a little older I began to understand what my dad really meant. So, I read some books on fish. And I even joined the local fishing club and started attending the monthly meetings. I learned that a fish is a cold-blooded animal and therefore is very sensitive to water temperature. That is why fish prefer shallow water to deep water because the former is warmer. Besides, water is usually warmer in direct sunlight than in the shade. Yet, fish don't have any eyelids (眼皮) and the sun hurts their eyes. The more I understood fish, the more I became effective at finding and catching them.

    When I grew up and entered the business world, I remember hearing my first boss say, "We all need to think like sales people." But it didn't completely make sense. My dad never once said, "If you want to catch a fish you need to think like a fisherman." What he said was, "You need to think like a fish." Years later, with great efforts to promote long-term services to people much older and richer than me, I gradually learned what we all need is to think more like customers. It is not an easy job. I will show you how in the following chapters.

    A story posted by The New York Post Monday tells the tale of Katrina Holte, a Hillsboro woman who quit her job to cosplay a 1950s housewife.

    Let me start by expressing admiration to Holte for using her 2019 freedoms to follow her 1950s dreams. Everyone should be so lucky as to get to decide what they wear and how they spend their time. That's the future our foremothers fought for.

    But as much fun as I am sure she is having living a vintage (复古的) life, which literally includes watching shows like "I Love Lucy" and listening to vinyl recordings (刻录碟片), I think it's important to remember that being a 1950s housewife was actually totally awful, and something our grandmothers and mothers fought against.

    For example, once I called my grandma and asked her for her recipe for Cloud Biscuits, these delicious biscuits she used to make that we would cover with butter and homemade raspberry jam on Thanksgiving.

    "Why would you want that?" she said. "Go to the store. Go to the freezer section. Buy some pre-made biscuits and put them in the oven."

    She straight-up refused to give me the recipe, because it was hard and took a long time to make. In her mind, it was a waste of time.

    Getting off the phone, it occurred to me that spending every day of your life serving a husband and five children wasn't fun at all. And then there are the grandchildren who eventually come along demanding Cloud Biscuits, a whole new expanded set of people to feed.

    She was basically a slave to those hungry mouths, cooking scratch meals three times a day.

    When she wasn't trapped in the kitchen, she had to keep the house clean, make sure she looked good enough to be socially acceptable, and make sure her kids and husband looked good enough to be socially acceptable. And she had no days off.

    I know my grandma loves her kids and her grandkids, her husband and the life she led, but man, it must have been a lot of thankless, mindless labor.

    No wonder everyone went all-in on processed foods when they came around. Imagine the nice break something like a microwave dinner would give a woman working, unpaid, for her family every single day?

    I also had another grandma. She was a scholar who helped found the Center for the Study of Women in Society at University of Oregon. She was a pioneering second-wave feminist who wrote books, gave lectures and traveled the world.

    But, she did all of that after divorcing my grandpa, when most of her kids were out of the house. Back then, in the 1950s and the 1960s, there was no illusion about women "having it all". How could that even possibly happen? If you were taking care of a family, waiting on your husband, you had no time to follow your dreams, unless you made that your dream.

    A lot of women took that approach. We call it Stockholm Syndrome now.

    And of course, these women I am talking about are upper-middle-class white women. Romanticizing the 1950s is especially disgusting when you think about how women of color and poor women were treated back then, and the lack of education and choices available to them.

    Because the women in this country demanded something approaching equality, Holte has the chance to live out her fantasy. Not every woman in America is so lucky.

    We still don't have pay equality and in many states, we still don't have autonomy over our own bodies. Poor women and women of color still lack the opportunities of their wealthy and white peers.

    And while it's getting better, women are still expected to be responsible for the emotional labor of running a household and raising the children.

    But at least we can get jobs. At least we don't have to sew our own clothes, wear a full face of makeup every day and spend hours making Cloud Biscuits some ungrateful kid will wolf down, barely remembering to say thank you.
