It’s a question anyone might ask in the future: Should your household robot be cool? Or practical? For Sony Corporation, robots ought to be entertaining. The company’s 41 robot, SDR—4 X, can sing and dance.
But for automaker Honda Motor Co Ltd, such 42 should perform useful tasks for their 43 masters.
“It is in the end a machine, a 44 ,” said Masato Hirose, Honda’s chief engineer.
Sony’s chief researcher Toshi Doi said robots performing such tasks as 45for ill or disabled people would not necessarily need a human 46 .
“The attractiveness of the SDR—4 X is its 47”, he said.
“It has feelings. It has instincts(直觉).” Drawing from its 48of 60,000 words, an SDR—4 X robot 49 last week that it can ask a 50 in a high voice: “Please 51still for a minute while I memorize your face.”
It also 52 off its ability to walk on uneven(不平的)floors, and come to its owner when it’s 53. While Honda’s robot is 54 used mainly for entertainment, it is 55 that one day it will be a useful companion. So its robot have been 56to be 120cm tall – more than twice the height of the SDR—4 X. Hirose said 120cm is the 57a robot that moves around a home should be.
“If you are going to have something that can move with 58 in a human surroundings(环境), then it is better to 59 the robot like a human,” he said.
Hirose said that he hopes the robot will be 60 enough so that he can buy one for himself and let it get him a beer.

How often do you change your hairstyle or ask for new dresses? You may be 31 to follow trends（潮流）in Western countries, but young people in the United States don’t care as much about
32 as you do.
A recent survey(调查) among high school 33 in China, Japan, South Korea and the US found that 34 teenagers care more about their appearance than young people in the US.
This survey was held in 156 high schools in the four countries. More than 7,000 teenagers were
35 about their views on life and the world. South Koreans, at 83 per cent, cared most about their looks. They were 36 by the Chinese and Japanese, while US students showed the least interest in fashion at only 33 per cent.
“The different results show 37 of cultural background（背景）,” said Sun Yunxiao from the China Youth and Children Research Centre. He explained that in the US there are many different 38 of beauty, so teens are more 39 to be confident about their appearance.
US teenagers’ high self-confidence is displayed（展示） in the 40 . About 85 per cent are happy with themselves. The percentage of self-confident Chinese students stands at only 30 per cent.
What’s 41 , US students showed more individuality（个性）, with 88 per cent 42 that “people should follow their own interests rather than 43 of others”. This is much 44 than South Korea’s 69 per cent, China’s 49 and Japan’s 48.
Japanese students, at 52 per cent, are most dissatisfied with modern society. Chinese and Koreans follow at second and 45 most dissatisfied.
“ 46 to the survey, Chinese students are happy and disciplined (有纪律的). They have a strong wish to make a difference. 47 Chinese students need to be more independent and learn how to relax,” said Sun.
The students have different 48 backgrounds. But home and places where friends gather are the favorite places all teens seek happiness.
Exams and worries about life after graduation cause much 49 among most of the teens

Ausubel of Rockefeller University in New York, US. says the key renewable energy sources, including sun, wind and biofuels, would all require vast 1 of land if developed up to large scale production1 – unlike nuclear power. That land would be far better left alone2, he says. Renewables look attractive when they are quite 2 . But if we start producing renewable energy on a large scale, the fallout is going to be horrible. Instead, Ausubel argues 3 renewed development of nuclear.
Ausubel draws his conclusions by analysing the amount of energy renewables, natural gas and nuclear can produce in terms of power per square metre of land used3. Moreover, he claims that as renewable energy use increases, this measure of efficiency4 will 4 as the best land for wind, biofuels, and solar power gets used up.
Using biofuels to obtain the 5 amount of energy as a 1000 megawatt nuclear power plant would require 2500 square kilometres of farm 6 , Ausubel says. "We should be sparing land for nature5, not using it as pasture for cars and trucks," he adds.
Solar power is much more efficient than biofuel in terms of the area of land 7 , but it would still require 150 square kilometres of photovoltaic cells to 8 the energy production of the 1000 MW nuclear plant. In another example, he says meeting the 2005 US electricity demand via wind power alone would need 780,000 square kilometres, an area the size of Texas.
However, several experts are highly critical 9 Ausubel’s conclusions. John Turner of the US government’s National Renewable Energy Laboratory says that 10 the US got all of its power from solar energy, it would still need less than half the amount of land that has been paved over for highways. Further, it need not 11 additional land. The US could get a quarter of its energy just from covering rooftops of 12 buildings, he says.
According to Turner, the same "dual use" also applies to wind power6. "The footprint for wind7 is only 5% of the land that it 13 . Farmers can still farm the land that the turbines are on8. Turner says looking solely at land use is an oversimplification of the 14 . "I’m not sure I’d want to build one of these nuclear plants in Afghanistan9, but we could 15 put in wind and solar power," he adds.

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't 1 it to be blue - the name has nothing to 2 the color of our closest celestial（天体） neighbor.
A full moon 3 on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the 4 moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be 5 in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up 6 New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when 7 of the moon enters the Earth's shadow. The 8 will not be visible in the Americas.
A full moon occurs 9 29.5 days, and most years have 12. 10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The 11 time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't 12 again until 2028.
Blue moons have no astronomical 13 , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a 14 in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon 15 after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar 16 a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the 17 decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a 18 moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay 19 on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm 20 celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.
Using prediction models, British and Australian researchers 1 that improving efficiency, increasing carbon capture and 2 fossil fuel dependence in farming would not be enough to 3 emissions targets.
But combining these steps 4 a 30 percent reduction in livestock（家畜） 5 in major meat-producing nations and a similar 6 in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.
The study found that in Britain, a 30 percent 7 intake of animal-source saturated（饱和的） fat by adults would reduce the 8 of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.
In Sao Paulo, Brazil, it could mean as 9 as 1,000 premature deaths reduced in a year, they said.
10 the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising 11 for meat, particularly in countries with growing economies, could 12 livestock production up by 85 percent from 2000 levels 13 2030.
The scientists said global action was needed to maximize the benefits of cutting meat production and 14 , and that the environmental 15 "may apply only in those countries that currently have high production levels."
The study was 16 in The Lancet medical journal as part of a series in climate change and health 17 the Copenhagen global climate summit scheduled next month.
In a second study, British scientists found that increased walking and cycling, and 18 cars, would have a much greater impact on health 19 low-emission vehicles in rich and middle-income countries.
Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential 20 impacts of their plans."

Don't blame genes for aging facial skin. A new study of twins suggests you can 1 those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.
Because twins share genes, but may have 2 exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues 3 in the latest issue of Archives of Dermatology.
Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is 4 more to environment and lifestyle than 5 factors.
But when it 6 skin cancer, the researchers say their findings support previous reports that 7 environment and genes affect skin cancer risk.
Baron's team 8 facial skin of 130 twins, 18 to 77 years old, who lived 9 in the northern Midwest and Eastern regions of the U.S. who were 10 the Twins Days Festival in Ohio in August 2002.
At this time, each of the twins also 11 reported how their skin burned or tanned 12 sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.
The study group 13 of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.
From these data, the researchers 14 strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental 15
16 contrast, sunscreen use and drinking alcohol appeared correlated with 17 skin damage.
Baron and colleagues say the current findings, which highlight ties between facial 18 and potentially avoidable 19 factors -- such as smoking, being overweight, and 20 overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't 1 it to be blue - the name has nothing to 2 the color of our closest celestial（天体） neighbor.
A full moon 3 on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the 4 moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be 5 in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up 6 New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse（月蚀） on New Year's Eve when 7 of the moon enters the Earth's shadow. The 8 will not be visible in the Americas.
A full moon occurs 9 29.5 days, and most years have 12. 10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The 11 time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't 12 again until 2028.
Blue moons have no astronomical 13 , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a 14 in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon 15 after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar 16 a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the 17 decades later, the definition caught on. For purists（语言纯正癖者）, however, this New Year's Eve full moon doesn't even qualify as a 18 moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay 19 on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm 20 celebrating, I'll take a peek（眯着眼睛看） at that brilliant orb（天体） as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

For some people, the sight of a mouse can be reason to scream. For other mice, the same sight can be reason to sing.
Mice will probably 21 sing their way to any concert, but researchers in the United States have found 22 that mice do, 23 , sing.
Scientists already knew that mice make ultrasonic(超声波) sounds—noises that are too high-pitched(高音的) for people to hear 24 special equipment.
To find out whether mice put such sounds together in song-like 25 , the researchers recorded the sounds of 1 mice. Using computer 26 , they were able to separate the sounds into specific types of syllables(音节), and found the mice produced about 10 syllables per second.
The results showed that nearly all of the mice repeated sequences(顺序) of syllables in different patterns. That’s enough to meet the definition of what scientists 27 song. But not all scientists are 28 _ that what the mice are doing is 29 singing. To prove it, the researchers must show that there’s learning involved. And, they need to __ 30 why the mice sing.
