    Dogs are likely to have complex emotions such as jealousy(嫉妒)and pride, according to a new scientific research.

    Dogs feel very jealous when they find that they are unfairly treated. And they do not like seeing their owners being kind to other creatures, especially other dogs. They often react negatively(消极地)when their owners bring home new pets, the research found. “Dogs show a strong aversion to unfair treatment,” Dr. Friederike Range of the Vienna University said.

    At first, people believed most animals lack(缺少)the “sense of self” , which is needed to experience so-called secondary emotions such as jealousy, embarrassment or guilt. These emotions are more complex than feelings such as anger or joy.

    Besides dogs research, another research includes cows, horse, cats and sheep, and all the results have shown that animals are far more self-aware than we thought.

    Dr Paul Morris, a psychologist at the University of Portsmouth who studies animal emotions, told The Sunday Times, “We are learning that dogs, horses, and perhaps many other species are far more emotionally complex than we ever realized. They can suffer simple forms of many emotions we once thought only primates (灵长类) could experience. ”

    In research among dog owners, Dr Morris found almost all of them reported jealous behavior by their pets. The dog often tried to keep their owner away from a new lover in the early days of a relationship.

    Behavioral experts suggest that owners should keep a close relationship with the dog as usual when a new pet or child comes along in order to prevent jealous activity from the dog such as interruptions with barking.

    On a flight from Dallas, Texas, to Cincinnati, Ohio, to visit a friend in 2013, event planner Paige Chenault daydreamed about the grand birthday parties she'd throw for her daughter one day. (Paige was five months pregnant at the time.) Then, flipping through a magazine, she saw a photo of an impoverished Haitian boy, skinny. "I thought, this kid has nothing," Paige says.

    The image stayed with her, and she resolved to do something to help. "I decided I would use my talents to throw birthday parties for homeless kids," Paige says. For the next four years, Paige and her husband, Colin, took time out from parenthood to visit shelters to determine how best to pull off the parties.

    Finally, in January 2017, Paige launched the Birthday Party Project, a nonprofit organization, and recruited friends and family to help decorate Dallas's 75- occupant Family Gateway Shelter with balloons and streamers, celebrating the birthdays of 11 boys and girls, with 60 more homeless kids in attendance. "That first party was better than I could have ever imagined," says Paige.

    Now Paige and her staff of three paid employees work with regional volunteers to plan monthly themed parties at 15 shelters across the country, some of which house abused or abandoned kids. Each child celebrating a birthday that month gets a $30 gift, a decorative place mat, and an individual cake or cupcake.

    One of Paige's favorite parts of each party is when the kids make a wish and blow out the candles. "They rarely get a chance to dream big," says Paige.

    Her daughter, Lizzie, now seven, often helps out at the parties. Paige says, "The one thing I've always wanted is for my kid to be generous."

    Being able to take advantage of truly unlimited data is a smartphone user's dream, but everyone I've talked to about 5G is more excited about the usage unlocked by next - generation wireless devices. From smart home security to self - driving cars, all the Internet - connected equipment in your life will be able to talk to each other at lightning - fast speed with reduced delay.

    "5 G is one of those forerunners, along with artificial intelligence, of this coming data age," said Steve Koenig, senior director of market research for the Consumer Technology Association. "Self - driving vehicles are emblematic in this data age - they show application of data completely. With one single task, driving, you have large amounts of data coming from the vehicle itself, and a variety of sensors (传感器)are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about conditions down the road. There's lots of data behind that task, which is why we need the speed and lower latency ((延迟).

    AR glasses and virtual (虚拟的)reality headphones haven't yet been inside the mainstream, but tech companies are joyfully saying that such equipment will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to improve - or even replace - smartphones.

    Ericsson showed at February's Mobile World Congress in 2019 how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on outside equipment for processing power.

    But don't get too excited. There's still a lot of work to be done in the meantime, including some necessary testing to make sure the radio plays nicely with basic systems and service construction so that 5G isn't concentrated only in big cities.

    Finland is the happiest place on Earth, according to the 2018 World Happiness Report of 156 nations.

    The report, released Wednesday by the United Nations'Sustainable Development Solutions Network, ranks the countries of the world based on six different categories of well-being: income, freedom, trust, life expectancy, generosity and social support. This year's report also pays special attention to the happiness of each country's immigrants.

    The U.S. dropped four spots from 2017 and landed in 18th place, and last year's winner, Norway, came in second place — followed by Denmark, Iceland and Switzerland.

    “The top five countries all have almost equally high values for the six factors found to support happiness, and four of these countries—Denmark, Switzerland, Norway and now Finland — have been in first place in the six World Happiness Report rankings since the first report" in 2012, "co-editor John Helliwell told CNN. “In a division with such excellent teams, changes in the top spot are to be expected."

    Rounding out the top 10 happiest countries was Canada in sixth place, then New Zealand, Sweden and Australia. The order of the top 10 nations changed from the 2017 list but the countries did not, according to the report. They were also 10 of the 11 top spots in the immigrant happiness category (including Mexico — 24th overall, but 10th in immigration).

    "The most striking finding of the report is the remarkable consistency between the happiness of immigrants and the locally born," Helliwell said in a statement. "Although immigrants come from countries with very different levels of happiness, their reported life evaluations resemble those of other residents in their new countries. Those who move to happier countries gain, while those who move to less happy countries lose."

    Other major world powers placed in significantly low spots on the list. Germany came in 15th, the UK was 19th — followed by Japan in 54th place, Russia in 59th and China in 86th.

    The report, based on surveys completed by citizen volunteers, came just under a week before World Happiness Day on March 20, when the UN declared to recognize "the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings around the world and the importance of their recognition in public policy objectives"
