1 . Hidden in the trees, behind the leaves, look closely and you’ll see eyes staring back at you. This is SlothBot, a robot inspired by the famously slow animal-sloth (树獭).
For the next several months, visitors to the Atlanta Botanical Garden will be able to observe the testing of the new high-tech tool in the battle to save some of the world’s most endangered species. Researchers are testing the SlothBot near the Garden’s popular Canopy Walk.
Built to take advantage of the low-energy lifestyle of real sloths, SlothBot demonstrates how being slow can be ideal for certain applications. Powered by solar panels and using innovative power management technology, SlothBot moves along a cable strung between two large trees as it monitors temperature, weather, carbon dioxide levels, and other information in the Garden’s 30-acre midtown Atlanta forest.
“Slowness is a design principle of SlothBot,” says Magnus Egerstedt, professor and chair in the Georgia Institute of Technology’s School of Electrical and Computer Engineering. “That is not how robots are typically designed today, but being slow and energy-efficient will allow SlothBot to stay in the environment to observe things we can only see by being present continuously for months, or even years.”
About three feet long, SlothBot’s imaginative 3D-printed shell helps protect its motors, gearing, batteries and sensing equipment from the weather. The robot is programmed to move only when necessary, and will locate sunlight when its batteries need recharging.
“The most exciting goal we’ll demonstrate with SlothBot is the union of robotics and technology with conservation,” says Emily Coffey, vice president for conservation and research at the Garden. “We do conservation research on endangered plants and ecosystems around the world, and SlothBot will help us find new and exciting ways to advance our research and conservation goals.”
“SlothBot could do some of our research remotely and help us understand what’s happening with pollinators(传粉者), interactions between plants and animals, and other phenomena that are difficult to observe otherwise," Coffey adds.

2 . Born blind is unfortunate in any case. But things were even harder for Srikanth Bolla who was born in a small village in India, where the common belief was that kids with disabilities were “of no use” and therefore, better off dead. Fortunately, Srikanth’s parents loved their son and refused to give him up. Instead, they encouraged the blind boy to dream big and reach for the stars.
Srikanth did not disappoint his parents. The now twenty-four-year-old man is the founder and CEO of Bollant Industries.
Of course, getting here was not easy. Being both blind and poor meant that Srikanth had to face hard challenges. As a young boy, Srikanth attended a regular school near his home. Unfortunately, the students and teachers didn’t quite like him because of his disability. As a result, the young boy was largely ignored and often spent the entire day alone.
Concerned this would hold back Srikanth’s development, his family decided to send him to a special school in Hyderabad. Sure enough, the young boy soon rose to the top of his class, earning awards in speech and debate competitions. But Srikanth was prevented from studying science when he reached 10th grade, because it was thought too dangerous for a blind student. Not wanting to give up, Sriksanth took legal action and became the first blind student in the country allowed to study science.
Later, after graduating from the Massachusetts Institute of Technology, Srikanth set up Bollant Industries in 2012. For just four years, it has become a powerhouse with over 450 employees,70% of whom are physically challenged.
Being disabled doesn’t mean being unable. “If the world looks at me and says ‘Srikanth, you can do nothing’, I will look back at the world and say I can do anything,” says the young man.

4 . Volunteering is a great way to help your community. It is something that people should be doing more often, because it is a great way to help out those less fortunate. Another reason that you should volunteer is that it has a lot of health benefits, which people don’t seem to really know about.
Reduce depression (抑郁)
Volunteering is a great way to decrease depression, especially if you are someone who doesn’t have a great support system at home.
A lot of volunteering involves packing boxes or moving things, and that is very good for your heart. You can actually walk the dogs and clean cages at a local animal shelter, which are all ways to stay active. If you are volunteering to do something you love, you may not even notice that it takes a great deal of physical energy, so it’s much better than just working out because you enjoy it.
Make you feel satisfied (满意的)
When you do voluntary work, you feel this satisfaction out of what you are doing, because you know you are helping other people. When you feel this satisfaction, your mental and physical health improves, and you just feel better overall (全面的).
Reduce anxiety
A.Help you stay active |
B.The results are as follows |
C.Build up your mental strength |
D.Here are four health benefits you can get through volunteering |
E.If you always feel embarrassed at new social occasions, then volunteer |
F.A lot of people become depressed because they don’t have friends or families |
G.In order to stay healthy, you have to keep a balance between your mind and body |
5 . The history of Azerbaijani cinema dates back to the end of the 19th century, during which, many excellent movies have been filmed, which are still watched and admired by everyone.
These movies were filmed in many beautiful places: from the comfortable and winding streets of the Icharishahar(Old City)—UNESCO World Heritage Site in Baku—to the beautiful fruit gardens and forests of beautiful areas of Azerbaijan.
Here, on these streets, one of the most famous Azerbaijani films, Arshin Mal Alan, directed by Rza Tahmasib, was filmed.
Filmed in 1945 and characterized by its amazing plot, beautiful music, great singing and acting, Arshin Mal Alan quickly became a box office sensation (轰动).
It remains an important cultural touchstone across Eurasia and has been translated into 86languages and shown in 136 countries.
The film is about pure love, women’s rights, and a young couple’s dreams for a modern way of life.
The plot tells us about a rich young man named Asker. One day, he decides to get married. However, according to the Eastern rule, a bride (新娘) needs to cover her face before the wedding. But soon he finds a solution to this problem. On the advice of his friend Suleyman, Asker dresses up as a street seller of cloth. By selling goods, these sellers can enter houses where the women and girls choosing their cloth don’t cover their faces. Now Asker can go into any yard and choose a bride.
The film has a lot of entertaining moments, songs and humour. The black-and-white version of this film has also been restored and can now be viewed in colour.
However, this is not the only movie that was filmed in the Old City. For example, in the films Amphibian Man and The Diamond Arm, you can see the streets well known to every Azerbaijaní.

6 . My 88-year-old grandfather and I are both starting 2022 as new college graduates. He was unable to continue school because he got married and started a family in the 1950s. Over the next few decades, he managed to balance his roles as a husband, a father of five, working at a local bank and taking a college class here and there.
Our higher education journey together at Palo Alto College began in 2016. I had just graduated from high school then and my grandfather, 82, was determined to take classes to make his lifelong dream of earning his bachelor’s degree become a reality. In 2017, we were both admitted into the University of Texas at San Antonio. I majored in engineering while my grandfather majored in literature. We would have lunch together and work silently side-by-side in the library. There were also many times when I drove him to school in my car. That was really special because I could always show off him and shout out my grandpa was here.
When COVID-19 broke out suddenly, my grandfather asked for leave from school. I often assisted him with his schoolwork online. Over the past year, his health has continued to decline and he now has difficulty speaking. As graduation day approached in December, my family and I persuaded university officials to approve of my grandfather having a degree of recognition. We had the expectation that he could have that memory before his death.
My grandfather was worried he would steal the show from my graduation moment when I told him we were graduating together. I told him this is our moment and that I want to share it with him. I’m so grateful and proud that I was able to have this moment with him. Applause run through the hall when my grandfather was awarded to his bachelor’s degree at the commencement (毕业典礼).
I appreciate my grandfather’s lifelong passion of learning and his strong wills.

9 . “You should get a cat,” my doctor said. “A cat?” I couldn’t even look after myself. I took a deep breath and carefully considered the idea of welcoming a feline (猫科的) friend into my life.
Adopting an animal during the height of the pandemic was far from easy. When my partner and I found Cinnamon, her adoption profile made her out as the perfect kitten. We filled out the paperwork and had a few weeks to prepare for her arrival.
When she came home, it became increasingly obvious that Cinnamon didn’t understand “no”, “stop it” or “don’t do that”. She was the worst cat I’ve ever owned. I was beginning to doubt my doctor’s advice.
We decided to start taking her for walks. I could barely leave the house before, but my heart couldn’t say no to Cinnamon. Cinnamon showed me what bravery looked like if there was a dog at a park, she would run toward it. She jumped without knowing where she would land. She loved adventure. I found myself mirroring her behavior after a while, jumping out of bed without a second thought. I began to find the motivation to get out of bed in the morning.
Cinnamon unfortunately passed away after a medical accident, leaving a cat-sized hole in my heart the day she left us at only six months old. I’m no stranger to sadness or grief, but losing my pet so suddenly was the most confusing emotional experience I’ve ever had. She was supposed to help me through more of my life than the three short months we had her.
Our time is often cut unpredictably, unmistakably short. It would be a shame to live life being anything less than brave and adventurous.

10 . In late May, America announced a plan to greatly expand offshore wind energy installations (安装) along the Pacific, Atlantic, and Gulf coasts, with the ultimate goal of adding clean energy enough to power 10 million homes by 2030. But is it realistic?
Those standing on the side of answering yes to this question understand that innovation (创新) is the key to pulling off the project. Unlike the open plains and rounded hills that traditionally host wind turbines, analyzing the seafloor situation for proper placement isn’t a simple exercise. With only 20% of the ocean seafloor mapped, we basically know more about the surface of Mars than we do Earth’s hidden depths.
Startup Bedrock is aiming to help shine a light on this problem by detecting the seas with its new electric self-driven underwater vehicles (AUV). Traditional ocean mapping techniques are ship-based, usually limited to the surface. Thus, traditional sea surveys can take up to a year to collect and process data. But Bedrock’s AUVs send data to a cloud-based platform called Mosaic that allows computers to start working with the results nearly right away and from anywhere in the world.
While using AUVs to map the seafloor helps improve our understanding of Earth’s oceans, Bedrock was careful that this do not come at the expense of sea life. The company uses smaller sensors that are close to the seafloor and operate in sound frequencies safe for animals. In addition, the AUVs only travel at roughly 2. 3 mph to 3. 45 mph, which reduces the chance of animal or environmental damage as they are moving.
Beyond the offshore wind industry, Bedrock is also exploring other ways its AUVs might benefit other marine-based efforts. “Currently our AUV surveys are designed for offshore wind projects, cable laying, nearshore environmental mapping for coastal management,” says Bedrock CEO and co-founder DiMare. “In the future, we’re also capable of serving new markets, helping to make ambitious government goals a reality.”
