Next time you raise an eyebrow at the views of your partner, friend, sibling (兄弟姐妹) or colleague, remember they could be helping to make you smarter.

    New research shows that intelligence is not fixed but can be boosted throughout adulthood by family members, bright mates and intellectually stretching (拉伸) careers.

    The study challenges the commonly held belief that intelligence is static by the age of about 18. Current scientific consensus suggests that intelligence is controlled by genes, with environmental factors such as schooling and nutrition playing a partial role up to this age. After this point, IQ scores stabilize (稳定).

    But James Flynn, professor of political studies and psychology at the University of Otago in New Zealand, argues that people can “upgrade” their own intelligence throughout their lives. He believes intellectual stimulation (刺激) from others is crucial as the “brain seems to be rather like a muscle – the more you use it, the stronger it gets”. However, the opposite is also true – so people sharing a home or workplace with those who are intellectually challenged risk seeing their IQ levels fall as a result.

    He found the “understanding quality” of a family changes the IQs of all members, especially children. It can “lift” or hold back, depending on the “gap between their brightness and that of their siblings and parents”. A bright ten-year-old with brothers and sisters of average intelligence will suffer a five to ten point IQ disadvantage, compared to a similar child with equally bright siblings. However, children with a low IQ could gain six to eight points by having brighter siblings and special educational treatment to help pull them up.

    Professor Flynn also concluded that although genetics and early life experiences determine about 80 percent of intelligence, the remaining 20 percent is linked to lifestyle. This means that people can raise their IQ, or allow it to fall, by ten points or more. Therefore, the best way to boost IQ level is to mix with bright friends, find an intellectually challenging job and marry someone cleverer.

    Does the future of filmmaking lie in virtual reality (VR) films?

    An ambitious team led by Yale senior Celine Tien might hold the answer to that question.

    Tien produced,directed and acted in Pippa's Pan,which she says is “one of the world's first live-action VR films.”The film,which was completed in April,mixes live action with VR sections.Some of the characters were created via animation（动画）and other techniques that distinguish the film from 360° VR videos like the ones frequently seen on YouTube.

    “360° VR videos are stagnant,which means you don't move with them and see a 360° view of whatever they're filming.”Tien explained.“What we're doing is immersive（沉浸式的）VR.When you put on the goggles (a kind of special glasses) you can physic.ally walk around in the space,pick up objects and engage with the environment.It's a huge difference.”

    The immersive VR film experience is different for everyone who interacts with the medium,but that doesn't mean the film's ending will change for each viewer.

    The film stars two Chinese-speaking actors."It's a love story about a woman suffering from Alzheimer's disease who is trying to bring back memories of her husband,"Tien said.

    The film has already been recognized by the VR industry.After handing in a short demo to the AT&T Developer Summit Conference,Tien and her team were invited to Las Vegas in January,where they came in third place.

    If you're dying to see the film already,your choices area bit limited: Pippa's Pan can't be seen in movie theaters unless they happen to have VR goggles available.According to Tien,many theaters in China will soon have the ability,which makes sense considering China is the film's target market.

    Pippa's Pan will be released in three languages: Chinese,English and Korean.“It can get spread in different ways: at film festivals with VR set ups and through HTC or Oculus headset stores,”Tien says.“If you have VR goggles you can download it and experience it yourself.We will also cooperate with movie theaters that have VR set ups.”

    On August 25, Hurricane Harvey made landfall in Southern Texas. The storm lasted for days, pouring almost 52 inches of rain. The downpour has caused widespread flooding, forcing more than 32,000 people into shelters and damaging the city's water supply system.

    The only silver lining is that disasters like these seemed to unite people. While the number of organizations and individuals that have gone all out to assist the victims is too many to list, here are some highlights of the outpouring of support that has made headlines this past week.

    A week ago, NFI player JJ Watt set up a website with a goal to raise $200,000. Soon he has collected over $18 million, and the donations keep pouring in. The thrilled football star wants to ensure the money is used where needed, saying, “We're trying to make sure it goes directly to the people. So our first wave of operation is we'll have nine semi-trucks going out there and I will go straight into the communities and hand stuff out there.”

    Ordinary individuals are not shying away from helping either. Jim McIngvale, the owner of a furniture store, turned his two 100,000-square-foot warehouse into shelters. When asked if he was concerned about the furniture that was being used by those living there, he responded, “These people are nice. They're taking care of the furniture. Furniture's made to be sat on, slept on or laid on. It's just a product.”

    There are also many unsung heroes that are putting their lives at risk to help others. After discovering an elderly man trapped inside his truck, local people made a human chain through the dangerous water to drag him to safety.

    While there is not much anyone could have done to prevent the loss, people across the US are doing everything they can to help its people recover.

    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

    Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport's rules require that a race walker's knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It's this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

    Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

    However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

    As a result, she says, some of the injuries associated with running, such as runner's knee, are uncommon among race walkers. But the sport's strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture. A new finding suggests that parents, social workers, psychologists and lawyers should be careful with their hands as well as their words. 

Gestures can be as informative as speech, but hand gestures are so common that we rarely notice we're using them. 

While the recall of both adults and children are easy to react to suggestion, the memories of children are known to be particularly influenced, said lead researcher Sara Broaders of Northwestern University. Kids are used to looking to adults to tell events for them and can be misled even if not intentionally(故意地). 

Previous research, for example, has shown that detail-loaded questions often cause false answers; when asked, say "Did you drink juice at the picnic?", the child is likely to say "yes" even if no juice had been available. It is not that the child is consciously lying, but rather the detail is quickly formed into his or her memory. 

To avoid this problem, social workers have long been advised to ask children only open-ended questions, such as "What did you have at the picnic?" But an open-ended question paired with a gesture, briefly meaning a juice box, is treated like a detailed question. That is, children become likely to answer falsely. 

And it isn't just a few kids: 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture. Gestures may also become more popular when talking with non-fluent language users, such as little kids, Broaders said as hand movements can impart meaning of unfamiliar words and phrases. "It certainly seems reasonable that adults would gesture more with children. "

In general, Broaders advises parents and other adults to "Try to be aware of your hands when questioning a child about an event. Otherwise, you might be getting answers that don't reflect what actually happened. "
