Most airlines go all out to ensure their passengers have the best possible flight experience. Now, Europe's low-budget airline, easyJet, wants to extend the positive experience beyond the plane ride with “Sneakairs”—smart shoes that allow visitors to explore new cities and towns without ever looking at a map.

    To transform Sneakairs from an ordinary shoe to a tour guide, all the wearer has to do is enter his or her desired destination into the easyJet smartphone app. A built-in GPS will determine the wearer's starting location while the Google Maps navigation(导航) tool will help chart the best route. Whenever a change of direction is necessary, the app will communicate with the appropriate shoe via the Bluetooth and cause it to vibrate(振动). For example, if the wearer needs to turn right, he/she will feel the sensation in the right shoe. Should the user miss the turn, the smart shoes will both vibrate at the same time, reminding him/her to change course.

    Visitors that wander off the suggested path or decide to take a break for a cup of coffee or a meal have nothing to worry about. The smart app will automatically determine the new location and chart out a new route, once the desired destination is reached. Sneakairs will vibrate three times to inform the user of the arrival and then go back to being ordinary shoes—until their navigation services are needed again!

    Sneakairs is certainly not the first navigation shoe in the market. However, easyJet is the first airline to offer them to passengers just as they are about to land in an unknown city. However, before Sneakairs can go mainstream, the easyJet team still needs to make some adjustments. Among the challenges that need to be addressed is the smart shoe's three-hour battery life, which is hardly enough for a tourist to catch all the delights a new or town has to offer!

    Jealousy is such a powerful emotion that at least one study has characterized it as the third leading cause of non-accidental homicide(杀人) in all cultures. In a recently published study, researchers experimented with dogs to see whether they, like humans, have the nature of jealousy.

In an experiment, the authors took 36 dogs—along with their owners—and observed the dogs' behavior as their masters interacted with three non-living objects. One object was a children's book, which they read aloud; another object was a plastic pumpkin lantern; and the third was a mechanical stuffed dog that gave out a bark when the owner pressed a button.

    Former studies concluded that babies were probably capable of jealousy. In the experiment, their mothers showed attention to a life-like doll instead of their child, and other objects. The babies were reportedly more likely to respond with “negative” behavior if their mother turned to pay her attention to the doll.

    In the dog experiment, authors instructed the dog owners to push the bark button on the stuffed dog's head, and then speak to it sweetly, while ignoring their own dog. After that, they showed attention to the pumpkin lantern, and read the children's book, while also ignoring their dog.

    It is interesting to see the dogs were far more likely to act aggressively when their owners spoke to the stuffed dog than when they paid attention to the other objects. One-fourth of the dogs snapped at the stuffed dog, while only one dog snapped at the lantern or the book. The dogs were also more likely to push or touch their owners as they interacted with the mechanical dogs, and tried to get in between the owner and the stuffed dog more frequently than the other objects.

    “One possibility is that jealousy developed in species of many young relying on the parents, the young compete for parental resources such as food, attention, care, and affection,” the authors wrote.

    When a driver slams on the brakes to avoid hitting a pedestrian crossing the road illegally, she is making a moral decision that shifts risk from the pedestrian to the people in the car. Self-driving cars might soon have to make such ethical (道德的)judgments on their own — but settling on a universal moral code for the vehicles could be a tough task, suggests a survey.

    The largest ever survey of machine ethics, called the Moral Machine, laid out 13 possible situations in which someone's death was unavoidable. Respondents were asked to choose who to spare in situations that involved a mix of variables: young or old, rich or poor, more people or fewer. Within 18 months, the online quiz had recorded 40 million decisions made by people from 233 countries and territories.

    When the researchers analyzed these answers, they found that the nations could be divided into three groups. One contains North America and several European nations where Christianity has been the dominant (占支配地位的)religion; another includes countries such as Japan, Indonesia and Pakistan, with strong Confucian or Islamic traditions. A third group consists of countries in Central and South America, such as Colombia and Brazil. The first group showed a stronger preference for sacrificing older lives to save younger ones than did the second group, for example.

    The researchers also identified relationships between social and economic factors in a country. They found that people from relatively wealthy countries with strong institutions, such as Finland and Japan, more often chose to hit people who stepped into traffic illegally than did respondents in nations with weaker institutions, such as Nigeria or Pakistan.

    People rarely face such moral dilemmas, and some cities question whether the possible situations posed in the online quiz are relevant to the ethical and practical questions surrounding driverless cars. But the researchers argue that the findings reveal cultural differences that governments and makers of self-driving cars must take into account if they want the vehicles to gain public acceptance.

    At least Barbara Wage, who heads a group working on autonomous-vehicle ethics at Audi in Ingolstadt, Germany, says such studies are valuable. Wage argues that self-driving cars would cause fewer accidents, proportionally, than human drivers do each year—but that people might focus more on events involving robots.

    Surveys such as the Moral Machine can help to begin public discussions about these unavoidable accidents that might develop trust. "We need to come up with a social consensus," she says, "about which risks we are willing to take."

Three grade 11 students from Harbour View High School, Canada, wanted to convey their message of fighting climate change to a younger audience. So, they wrote a children's book named Keeping It Cool as part of a project.

Upon receiving their first order of 12 copies, Claire Malco, the illustrator of the book, vividly recalls the moment when the realization struck. "I just sat there with my mouth open and was like, wow, this is actually happening," Malco told CBC News.

Coauthored by Joanna Jackson and Olivia Jordan, the book employs age-appropriate analogies (类比), coupled with vibrant illustrations, to promote actions kids can take against climate change. To explain the concept of the atmosphere, for example, the young authors drew a bubble(气泡) around Earth throughout the story. They also call for actions, such as planting trees and vegetable gardens – explaining how plants absorb CO2 from the "bubble" atmosphere just like a vacuum cleaner (真空吸尘器). The book also tells kids how they can avoid polluting the bubble by trying to walk, bike or scoot instead of taking a car or bus.

"The entire second half of the book is just things kids can do without needing their parents' support … We wanted it to be something that every kid could finish," Jordan explained to CBC News.

On Earth Day, the students visited a local elementary school where they read their stories and facilitated discussions about the text with every grade 5 class. They spread awareness that, regardless of age, anybody can help make a positive impact on Earth's climate."Educating students was the intention when writing this book. Having the opportunity to present to 10 different classes helped us gain insight on how to better our presentation and content, as well as see the impact this book will have on students," the students told Our Canada Project.
