The behaviour of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important—is not enough to achieve such reductions: the behaviour of the people using the building has to change too.

The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency, which instead focus on architectural and technological developments.

"Technology is going to assist but it is not going to do everything," explains Katy Janda, a UKERC senior researcher, "consumption patterns of building users can defeat the most careful design." In other words, old habits die hard, even in the best-designed eco-home.

Another part of the problem is information. Households and bill-payers don't have the knowledge they need to change their energy-use habits. Without specific information, it's hard to estimate the costs and benefits of making different choices. Feedback facilities, like smart meters and energy monitors, could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.

Social science research has added a further dimension, suggesting that individuals' behaviour in the home can be personal and cannot be predicted—whether people throw open their windows rather than turn down the thermostat, for example. Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.

People who grow up outside of cities are better at finding their way around than urbanites, a large study on navigation suggests. The results, described online on March 30 in Nature, hint that learning to handle environmental complexity as a child strengthens mental muscles for spatial skills. 

Nearly 400,000 people from 38 countries around the world played a video game called Sea Hero Quest, designed by scientists and game developers as a fun way to collect data about people's brains. Players piloted a boat in search of various targets.

On average, people who said they had grown up outside of cities, where they would have probably encountered lots of complicated paths, were better at finding the targets than people who were raised in cities.

What's more, the difference between city residents and outsiders was most obvious in countries where cities tend to have simple layouts (布局), such as Chicago with its streets laid out at 90-degree angles. The simpler the cities, the bigger the advantage for people from more rural areas, cognitive scientist Antoine Coutrot of CNRS and his colleagues report.

Still, from these video game data, scientists can't definitively say that the childhood environment is behind the differences in navigation. But it's possible. "As a kid, if you are exposed to a complex environment, you learn to find your way, and you develop the right cognitive processes to do so," Coutrot says.

Other factors have been linked to navigational performance, including age, gender, education and even a superior sense of smell. Figuring out these details will give doctors a more precise baseline (基准) of a person's navigational abilities. That, in turn, might help reveal when these skills weaken, as they do in early Alzheimer's disease, for instance.

Do you think cookies can tell stories? Jasmine Cho, 35, does.

A baker, artist, entrepreneur and activist, Cho tries to spread knowledge about social justice issues and diversity through the delicious medium of cookies.

It was in high school that she discovered her love of baking. At a sleepover a friend taught her how to make a dessert, "sort of demystifying baking and that whole process".

Later, Cho realized her second passion: learning more about her Asian, American culture. An elective in college that taught Asian-American immigrant experiences brought an emotional moment for her. "So many emotions came up that I just couldn't articulate. It was like this mix of anger, of relief, empowerment, sadness..." Cho said.

Cho realized she could combine these two passions to educate others about influential Asian American people and showcase matters that were important to her. With her online bakery, she designed cookie portraits about people she admired and posted the images on Instagram. "I don't think I ever really knew how to communicate these stories until I found cookies," Cho said. "Cookies are just so disarming. Who doesn't like cookies?"

One cookie that Cho has identified with deeply is one she made of George Helm, a Hawaiian activist in the 1970s.

"It's insane the amount of injustice that the native Hawaiian population has faced as well through the whole annexation (吞并) of the kingdom. There were so many horrific stories that I heard about nuclear testing and the fallout ( 核爆炸后的沉降物) impacting native Hawaiian populations in all of this," Cho said, "George Helm was one of those activists who really represented the spirituality of the native Hawaiians and the connection to their land, to nature."

Among her amazing cookie art are other political figures such as Larry Itliong, a Filipino-American labor organizer, and pop culture figures such as Keanu Reeves, a Canadian actor.

Cho hopes her cookie art continues to inspire people to be creative and think positively.

"Instead of trying to think of something new and original, just look inward and see, maybe there's already a passion or a love that you have," Cho said. "Use that for something that will serve the world in a better way."

The Fitting-in of Suzy Khan

The first time I saw Suzy Khan, I knew I had to help her. She was really small for her age of 12. The boys in my class often 1  about her and laughed their heads off. She would open a book, pretending to read, with tears dropping on the open page.

All I knew was that she was an orphan (孤儿) from Africa. She had just been adopted by a family in town who 2  that the best way for her to learn American ways of life was to be with American kids. I looked down at this 3  girl and promised myself that somehow I would help her.

But how could I help her 4  in with us? There had to be a 5  .

One day, when I went into the classroom, I saw that Suzy had 6  her geography book to a picture of a train, and in her notebook, she had made a(n) 7  copy.

I was surprised and thought that she could do something in the coming 8 show. So, I took her to see the art teacher, Miss Parker, and showed her what Suzy had 9 . "why, it's wonderful," said Miss Parker, who then showed us a poster she had painted 10 the talent show. "I need more of these, but I just don't have enough 11 . Could you help me, Suzy?"

On the day of the talent show, Suzy's 12 were everywhere — all over the hall and all over the school, each one different.

"And finally," said Mr Brown, the schoolmaster, at the end of the show, "we have a (n) 13 award. I'm sure you've all noticed the wonderful posters." Everyone nodded. "One of our own students 14 them."

I could hear everyone whispering. "Who in our school could draw 15 well?"

Mr. Brown waited a while before saying, " 16 this student worked so hard on the posters, she deserves a 17 ,too. Our mystery(神秘) artist is our new student — Suzy Khan!"

Mr. Brown thanked her for all the wonderful posters and gave her a professional artist's set. "Thank you," she cried.

I 18 , at that time when I was looking at her excited face, she'd probably never 19 anything in her whole life.

Everyone started to 20 their hands. Suzy Khan gave them a shy smile and the applause was deafening. I knew then Suzy was going to be all right.

— It is said that she hired a fitness instructor last year and ____ since.

—I'd like to, but I'm afraid I ____ a very important meeting when you return.
