A Teenage Inventor

    The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

    Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia's method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia's method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn't have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

    Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

    "What affects one country affects everyone," Olivia told CNBC. "We have to work together to find answers to the huge challenges which cause harm to the global health." The Connecticut's teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

    Olivia hopes her success will inspire other girls interested in science and computers. "I would just encourage girls to try it in the beginning, and remind them that they don't have to feel naturally drawn or feel like they have a special talent for maths or science," she told CNBC, "but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests."

    After spending a long day driving the day before, Steinkamp left his hotel around 5:30 a.m. to a funeral in Green Bay, Wisconsin. About half an hour into his journey, he noticed a small strange sound coming from his front tire. By 7 a.m., he still had 70 miles ahead of him, but the noise was so loud that he knew he had no choice but to stop.

    Steinkamp figured there was little possibility that anyone in Wild Rose, Wisconsin-a tiny town with a population of 725-could help so early in the morning. Still, he look his chance at an auto repair shop. Luckily, Steinkamp spotted Glenn Geib stocking the shelves, and he asked for help.Giving Steinkamp a quick look, Geib asked why he was so dressed up, and Steinkamp explained his dilemma.

    The mechanic checked the car and told Steinkamp what he'd feared: the wheel bearing（轴承）was failing. Fixing it would take a few hours, but there was no chance the car would make it that distance without repairs.

    "I must have looked pretty stressed out at this time because Glenn then reached into his pocket, pulled out the keys to HIS vehicle and said 'Take my truck and get going,'" Steinkamp wrote in a Facebook post.

    The men had met just 10 minutes before and didn't know each other's names, but Geib insisted. Steinkamp made it to the funeral. When he came back to the garage seven hours later with a thankful heart, he stuck around to chat with Geib.

    "The 74-year-old mechanic turned a terrible day into a good one with a great lesson." Steimkamp wrote, "Just be kind and help if you can."

The Rapid Rise and Fall of Robot Babysitters

    During the winter of 2017, an 18-year old college student named Canon Reeves spent much of his time trailing a knee-high robot around Fayetteville, Arkansas, as it delivered Amazon packages to students. The robot, created by a start-up called Starship Technologies in 2014, is basically a cooler on wheels; it uses radars, sensors, and nine cameras to make deliveries. Reeves's job was to monitor how it handled various grounds, field comments from the public, and press the off switch if necessary. He said, "People would also ask if it could deliver beer." It couldn't.

    Broadly speaking, jobs of caring for robots fall under the umbrella of careers in automation, which include maintenance, engineering and programming. The demand for people with this skill set is considerable, with 20 million to 50 million new jobs to be expected in this category by 2030, according to the Mckinsey Global Institute. In the year that ended in June 2018, Indeed.com had almost three times the number of positions on the recruitment committee that ended in June 2016.

    Over the last year, a 34-year-old businessman named David Rodriguez spent hundreds of hours following a machine called the KiwiBot around UC Berkeley's campus while it delivered Red bull and other drinks to students. To retrieve (检索) orders, the app encourages students to give the robot a wave; the robot's digital eyes will roll depending on its mood. Rodriguez, who heads business development for the start-up, was tasked, early on, with monitoring the KiwiBot for problems – even carrying it, should the motors fail. Since April 2018, though, the KiwiBot has largely been left unattended, and the majority of human interactions involve technical checks and loading food into the robot. To eliminate the boring work, the team is developing a restaurant robot to collect and load orders – which could happen in 2020. However, Rodriguez assured me that his staff won't be out of work. Everyone holds double roles in the company. Greater robot self-governing just means employees will shift their focus to accounting, engineering, and design.

    Mckinsey estimates that millions of jobs globally could be lost to automation by 2030. "A huge number of jobs will be produced as autonomous vehicles are released into the environment," Ramsey said. In 2016, Bosch started training students from Schoolcraft College, a community college in Michigan, in autonomous-vehicle repair; Toyota has trained students in maintenance as well. "We might even see a return to low-level jobs where people come and fuel the car for you," Ramsey said. "Until we can wirelessly charge, someone needs to refuel them." The hardest-to-automate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.

    Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.

    The cottages could be an example of the industry' s odd love affair with "low technology," a concept associated with the natural world, and with old-school craftsmanship (手艺) that exists long before the Internet era. Low technology is not virtual (虚拟的) —so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by hand in the late eighteen-hundreds, are an obvious example, but Twitter's designs lie on the extreme end. Other companies are using a broader interpretation (阐释) of low technology that focuses on nature.

    Amazon is building three glass spheres filled with trees, so that employees can "work and socialize in a more natural, park-like setting." At Google's office, an entire floor is carpeted in glass. Facebook's second Menlo Park campus will have a rooftop park with a walking trail.

    Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. "We have lost the connection to the maker in our lives, and our tech engineers are the ones who feel impoverished (贫乏的) , because they're surrounded by the digital world," he says. "They're looking for a way to regain their individual identity, and we've found that introducing real crafts is one way to do that."

    This craft based theory is rooted in history, William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after the Industrial Revolution. The Arts and Crafts movement defined itself against machines. "Without creative human occupation, people became disconnected from life," Morris said.

    Research has shown that natural environments can restore(恢复) our mental capacities. In Japan, patients are encouraged to "forest-bathe," taking walks through woods to lower their blood pressure.

    These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office—even simple views of trees and flowers—felt their jobs were less stressful and more satisfying. If low-tech offices can potentially nourish the brains and improve the mental health of employees then, fine, bring on the cottages.

    Like any new ninth­grader on the first day of school, Joemar Class had ninth­grader emotion (情绪). He's not used to school in Hartford. He's used to going to school in his hometown of Florida, used to seeing his friends, used to having class in Spanish.

    "Nervioso，"he said in Spanish.

    We first met Joemar in mid­October in the San Juan Airport. His father, Guillermo Class, had sold his car to buy plane tickets to get his kids and fly them up from Puerto Rico. The island was almost destroyed (毁坏) by the deadly storm — Hurricane Maria.

    Now, they are settling into their new home in Hartford's South End. A week later, and, using his wife's car, Class drove 16­year­old Joemar to his first day at Bulkeley High School. After a short ride, he got out in front of his new school. Inside, he met Gretchen Levitz — the school's program director.

    "I see you have a new uniform (校服)," Levitz said. "You look great. Are you ready for a good first day？"

    Then he met a couple of teachers.

    "Hello," they each said in Spanish. They asked where he's from, and told him they were happy to see him. Then, Levitz took him on a quick tour of the school before classes began — to her office, the school store, the library, and the dining hall.

    A total of 19 languages are spoken in Bulkeley High School. "We have so many new students coming here from other countries every single day," Levitz said. "So it's not like he's the only one who has that feeling."

    "You could tell he's a little worried," Guillermo said as we left. "But, at the same time, he's looking forward to it."

Christmas in the United States is traditionally a time of gift-giving and family gatherings. But small towns across the country have their own traditions.

Middleburg, a small town in the state of Virginia, is known for its horses. For more than 50 years, Middleburg has organized a yearly Christmas parade. Men and women ride horses through the woods and fields. They follow hunting dogs as they search for a wild fox. But first, these hunters ride in the yearly parade, wearing their bright red hunting clothes and hats.

John Hale, a citizen of Middleburg says many city people visit his town." We have a lot of people from an urban area that come to visit, but it incorporates a lot of the old traditions." The night-time hayride is one such tradition. Small groups gather under the moonlight on an open wagon (四轮马车) filled with hay (干草). The passengers sing as farm horses pull the wagon slowly across the fields.

There are some newer traditions, too. Trey Matheu works at the nearby Salamander Resort. He says a visit to Middleburg is a chance to slow down for a day. He says Middleburg can be a calming, peaceful place without tension.

"Middleburg is an opportunity to take a step back, to take a deep breath, and understand that even though life is moving on at a very fast pace, there's really an opportunity where you're allowed to step off for a little bit."

Parade organizers say more than 13, 000 people attend even in below freezing weather. But if you ask, you will hear many different reasons why people come to watch the parade:

"I come here because I'm from a small town. I like how everybody comes together."

"I live right down that street, right there. And that's my dog."

Middleburg looks its best at Christmastime. That may be why so many people return each year.
