1 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?

2 . You can remember the face, but can't put a name to it. Many of us have been caught in this embarrassing situation. But researchers say it is often easier to remember someone's name than what they look like.
Twenty-four volunteers were shown 40 pictures of strangers, paired with random(随机的) names. They were given time to memorize the faces and names before being tested on which they thought they had seen before.
The participants could remember up to 85 percent of the names but only 73 percent of the faces. When they were shown a different picture of the same person, the participants could recall only 64 percent of faces, according to the study, led by the University of York.
That may be because faces are only recognized visually(视觉地), while names can be both spoken and written down so appear in our visual and audio memory. When people were shown famous people, they also remembered their names more accurately than their photographs. Co-author Dr Rob Jenkins, from the university’s psychology department, said, ''Our study suggests that, while many people may be bad at remembering names, they are likely to be even worse at remembering faces. This will surprise many people as it is against our initial understanding. Our life experiences with names and faces have misled us about how our minds work. '' Remembering names gets harder with age, leading to many uncomfortable moments for middle-aged people when they run into people they know.
But to study whether names are harder to recall than faces, the researchers, whose findings are published in the Quarterly Journal of Experimental Psychology, used a ''fair test'' where the participants were presented with strangers' names and faces.

3 . 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.

4 . Cassandra Warren, a baby-sitter, was in a rush and feeling a little overcome with work and planning her 200-person wedding. As she was getting invitations for her weddings in the mail one day last year, she hurriedly addressed one to her aunt and uncle in Oregon.
A week later, the invitation came back, with a handwritten note on the return envelope: “I wish I knew you. Congratulations! I’ve been married for 40 years—it gets better with age.” A $ 20 bill was inside.
Cassandra was at a professional crossroads and had been having a tough day. In fact, she nearly broke down, telling her husband-to-be, Jesse Jones, about her depression just as she opened the misdirected envelope. And the magic envelope wasn’t finished with its surprises. Cassandra looked closer and saw that on the envelope were “Live long and prosper”, a nod to space-based film Star Trek (《星际迷航》).
Casandra and Jesse have no idea who the anonymous note writer is. But they figure the Star Trek reference was because the person noticed the “fandom” corner of their invitation, which had both a Star Wars light-saber (光剑) and a Harry Potter wand (魔杖). “She assumed we’d understand her message,” Cassandra says. “Which we did.”
The following night Casandra and Jesse went out o dinner with a friend who was going overseas with the military. They happily put the $20 toward their bill. Then Casandra stopped by a store and bought another card—a thank-you card. She wrote her aunt and uncle’s incorrect address on the envelope again to “Kind Stranger.” Inside, she wrote, “Thank you for the note and taking the time to send it. Not many people would have done that. It was a big blessing after the day I was having. I am thankful for people like you still being in the world.”

| D．Cassandra doesn’t know her uncle and aunt’s address. |
5 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
