The similarities between elephant and human behavior has been a curiosity to scientists worldwide. These huge beasts are not so different from us. Their devotion to their family is just as powerful as the friendships between humans. In order to prevent future elephant attacks, people must first understand the similarities between elephants and themselves.

    Because deaths are felt so deeply in elephants, memories of people harming or killing other members are not forgotten. Due to the Uganda-Tanzania War in Africa, poaching (偷猎) elephant increased during the 1970's and continued, despite government restrictions. However, ecologists like Eve Abe did not see this as simple poaching; they saw it as a “mass destruction. “Elephants that have witnessed the murder of a matriarch, are more likely to become violent and attack humans. Many aggressive elephants do not act without reason; they are suffering from Post Traumatic Stress Disorder (PTSD). At a young age, humans invade their life, kill their parents, and ultimately destroy their peaceful environment. More and more calves live neglected lives without a mother figure, and have to become a parent early for survival. Humans that had a difficult childhood or early family life also suffer from aggression and pain. Young elephants have been known to have “nightmares,” waking up suddenly and screaming. These are clearly signs of stress, as males grow up to be increasingly hostile (敌对的) humans and target certain villages where painful experiences had occurred.

    Although many see elephants as massive, violent, and simple-minded animals, their social structure is not unlike many human societies. Humans and elephants have been on parallel paths. However, if people continue practicing ignorance over the cruel treatment of these creatures, then collision will become inevitable. Cruel treatment of elephants still goes on, but by understanding the similarities between us, it can be stopped.

    Artificial intelligence（AI）is making it possible for companies to monitor workers' behavior in great detail and in real－time（实时的）. Start to slack off（懈怠）and AI could talk to your boss.

    One company offering such services is London－based start－up Status Today. Its AI platform relies on a regular supply of employee data, including everything from the files you access to when you use a key card.

    From this, it builds a picture of how employees normally function and signals any unusual performance. The idea is to spot when someone might become a security risk by doing something different from their usual behavioral patterns. “All of this gives us a fingerprint of a user, so if we think the fingerprint doesn't match, we raise a warning, ”says Mircea Dumitrescu, the company's chief technology officer.

    The system also aims to catch employee actions that could accidentally cause a security breach（漏洞）, like opening malware（恶意软件）. “We're not monitoring if your computer has a virus。”says Dumitrescu. “We're monitoring human behaviors. ”

    But catching the security breach means monitoring everyone, and the AI can also be used to track employee productivity. “It seems like they are just using the reputation of AI to give an air of lawfulness to old－fashioned workplace surveillance（监视）, ”says Javier Ruiz Diaz of digital campaigning organization the Open Rights Group. “You have a right to privacy and you shouldn't be expected to give that up at work. ”

    Exactly how companies use the system will be up to them, but it's hard to shake the picture of an AI constantly looking over employees' shoulders. “It will bother people, and that could be counterproductive if it affects their behavior, ”says Paul Bernal at the University of East Anglia.

Phil Legg at the University of the West of England says it will never catch every security risk. “If people know they're being monitored, they can change their behavior, ”he says.

In an attempt to fight with the nation's food wastage problem, Denmark has opened the world's first supermarket that sells expired(过期的) or damaged products. Ever since the grand opening in Copenhagen last Monday, people have been lining up outside WeFood for a chance to purchase discounted items that would otherwise have ended up in the trash because of damaged packaging or very short use—by dates. Food, cosmetics, and other household items at WeFood are priced at least 30 to 50 percent lower than at regular stores.

    “WeFood is the first supermarket of its kind in Denmark and perhaps the world, as it is not just aimed at low-income shoppers but anyone who is concerned about the amount of food wastage produced in the country,” said project head Per Bjerre. “Many people see this as a positive and correct way to approach the issue.”

    While Denmark alone is estimated to waste about 700,000 tons of food every year, the United Nations has stated that globally, food waste amounts to 1.3 billion tons. About 795 million people in the world are undernourished. Denmark, however, has adopted several measures to clean up its act, wasting 25% less food than it did five years ago.

    The WeFood project is a collaboration between The Food Bank and charity DanCurch Aid. Together they raised nearly $150.000 over the past year through crowdfunding. They also had to face many obstacles while convincing the government to permit the sale of expired food. They were finally allowed to carry out the project, and the store is now run only by volunteers. Profits are used to fund DanChurch Aid's other projects in developing nations like South Sudan and Bangladesh.

    Provided WeFood's remains popular in the long term and if it is able to maintain its food deliveries, DanChurch Aid plans to open multiple branches across Denmark.

In 2011, Nancy Ballard went for a routine check-up that turned into something extraordinary. In fact, she was carrying a painting of a plant she'd done when she arrived at her doctor's San Francisco office. "It would be great if we had artwork like that for our chemotherapy(化疗) rooms," the nurse said. Ballard asked to see one. 

She was shocked by what she found. The walls were dull and bare, and the paint was falling. It was a depressing room for a depressing routine—patients were restricted to chemo drips for perhaps several hours, often with nothing to look at other than those sad walls. Ballard didn't have cancer herself, but she could sympathize with the patients. "I couldn't imagine how anyone could even think about getting healthy in a room like that," she says. As it happened, Ballard's physician, Stephen Hufford, was ill with cancer himself, so finding time to decorate the rooms was low on his to-do list. So Ballard made it her task to brighten up the place. 

She started by emailing 20 local designers. "I wrote, ‘You don't know me. But my heart hurts after seeing these rooms,'" she remembers. She then asked whether they would donate their time and money to transform just one of Dr Hufford's rooms each. 

As it happened, six of them wrote back almost immediately. Six rooms got new paint, light fixtures, artwork and furniture. Dr Hufford was delighted. "All the patients feel relieved of the pain because of it," he said. He even noted that his own tone of voice was different in the rooms and that he was better able to connect with his patients. 

Ballard was so encouraged by the patients' reactions that she created a non-profit organization to raise money and decorate more spaces. Since then, she has worked on 20 projects, including one in Pennsylvania. "We were in Philadelphia for a ribbon-cutting(剪彩), and a woman was there on her third battle with cancer," says Ballard. "When she saw what we'd done, she said, ‘I'm gonna beat it this time. I thought I wasn't going to, but now I know I'm gonna beat it.'"
