an accelerating speeda shift to city centersa new focus on small citiesan ever-increasing demandPeople can live without private cars.

You feel the same emotions – it is just as raw, just as fresh… You can't turn off that stream of memories, no matter how hard you try.

While excessive optimism can promote bad investment patterns, resulting in a real-estate bubble, the report's writers downplay that potential outcome in that it has not yet occurred.

Where are you in the cycle of renewal: Are you actively preserving the present, or selectively forgetting the past, or boldly creating the future? What advice would Leah give you to move you ahead on your journey? Once we're on the path of growth, we can continually move through the seasons of transformation and renewal.

When you can quote a specific number like a fifth of the patients were able to quit, that's compelling.

What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.

Viewing the past in high definition can make it very difficult to get over pain and regret.

Veiseh can even put a date on when those tapes started recording: 15 December 2000, when he met his first girlfriend at his best friend's 16th birthday party.

They can only afford small apartments.

There's part of this sickening horror of knowing you're walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second.

The people with HSAM I've interviewed would certainly agree that it can be a mixed blessing.

The middle-aged person, Barth continued, can see death in the distance, but moves with a measured haste to get big new things done while there is still time.

The least that can be concluded from this research is that companies need to think harder about managing teams.

The bulk of the research shows that there may be a pause, or a shifting of gears in the 40s or 50s, but this shift can be exciting, rather than terrifying.

She can add multiple details to the design to communicate her idea.

Previous behavioural studies have shown that learning new information can lead to forgetting.

People can enjoy services around the clock.

Loosely managed teams can become hotbeds of distraction—employees routinely complain that they can't get their work done because they are forced to spend too much time in meetings or compelled to work in noisy offices.

Leah easily could have fallen into a trap of feeling content; instead, her energy sparked a period of experimentation and renewal.

It can enlarge our brain capacity.

It can easily be made into a work of art.

It can bring wealth and honor to them.

It can be very hard to forget embarrassing moments, says Donohue.

It can be terrifying for the unprepared.

It can be quite rosy.

It can be burdensome.

It can be a new phase of one's life.

Interestingly, their memories are highly self-centred: although they can remember autobiographical life events in extraordinary detail, they seem to be no better than average at recalling impersonal information, such as random ( ' , 任意选取的) lists of words.

Instead of giving people practice, the gradual reduction likely gave them cravings ( ' , 瘾) and withdrawal symptoms before they even reached quit day, which could be why fewer people in that group actually made it to that point.

I could tell you everything about every day after that.

I could imagine what the teacher was saying or what it looked like in the book.

HSAM can be both a curse and a blessing.

Fantasy proneness could be considered a tendency to imagine and daydream, whereas absorption is the tendency to allow your mind to become absorbed in an activity – to pay complete attention to the sensations ( ' , 感受) and the experiences.

Emailing the neuroscientist and memory researcher Jim McGaugh one day, she claimed that she could recall every day of her life since the age of 12.

Donohue, now a history teacher, agrees that it helped during certain parts of her education: I can definitely remember what I learned on certain days at school.

Could he help explain her experiences?McGaugh invited her to his lab, and began to test her: he would give her a date and ask her to tell him about the world events on that day.

Calling out our fears explicitly, as Leah did, can help us act decisively.

But at least, she says, they can maximize the odds of success.

As much as we would like to cling on to our past, even the saddest moments can be washed away with time.

With Facebook she could stay connected with her family no matter how far away they were.

With Facebook she could keep her relatives up to date on what she was doing.

This behaviour may have evolved as dogs gradually learned they could benefit from avoiding conflicts with humans.

There is lots of snow around, and the ground freezes, which can make life difficult for animals.

She could see their photos and read their status updates.

Mules have strong muscles like horses; but they eat less, can work longer, and are gentler, like donkeys.

It was like living in an age you could never have imagined, and that never has come back.

If I could go back in history and live when I liked, I wouldn’t go back very far.

And men were in jeans, and could wear their hair long too.

You should live your life attempting to identify and control those things which you can genuinely control.

You can't just say, ‘Let's put this person in a residential care home instead of a nursing home—she will be much better off, Dr.Robison said.

Yet I, too, have resisted the idea that food shortages could bring down not only individual governments but also our global civilization.

Worry only about things that you can control.

Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate.

We can live a peaceful life despite the various challenges of the modern world.

Today, when time zones have less and less meaning, there is little tolerance for offices' closing for lunch, and worsening traffic in cities means workers can't make it home and back fast enough anyway.

This danger can be avoided, according to computer science professor Stuart Russell, if we figure out how to turn human values into a programmable code.

These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times.

The findings shed light on normal age-related changes in mental function, which could aid in understanding the process of dementia ( ' , 痴呆), according to the researchers.

The doer of a good deed can feel spiritually rewarded even when they gain no concrete benefits.

The author has come to agree that food shortages could ultimately lead to the collapse of world civilization.

Stop worrying about what you can not controlAs we begin to examine our life, Soupios says, we come to Rule No.

States fail when national governments can no longer provide personal security, food security and basic social services such as education and health care.

Soupios say following the 10 Golden Rules based on ancient wisdom can guide us to the path of the good life where we stop living as onlookers and become engaged and happier human beings.

Since industrialization, maintaining such a slow cultural metabolism has been much harder, with the long midday meal shrinking to whatever could be stuffed into a lunch bucket or bought at a food stand.

Robots could also learn values from drawing patterns from large sets of data on human behavior.

Philip Sloane, a geriatrician ( ' , 老年病学专家 ) at the University of North Carolina: In a way, that could be liberating for families.

Personality isn't destiny ( ' , 命运 ), and everyone knows that individuals can learn to change.

Patterns of childhood eating can be hard to break when we're adults, which may mean that kids of depressed moms end up dying younger.

Once driverless cars are actually for sale, the early adopters will be the people who can afford to buy them.

Not everyone wants a driverless car now—and no one can get one yet—but among those who are open to them, every age group is similarly engaged.

More people who lived in cities and suburbs said they wanted to try driverless cars than those who lived in rural areasWhile there's reason to believe that interest in self-driving cars is going up across the board, a person's age will have little to do with how self-driving cars can become mainstream.

Millions of irrigation wells in many countries are now pumping water out of underground sources faster than rainfall can refill them.

Just because I have a business relationship with an individual and I can profit from that relationship, it does not necessarily mean that this person is my friend, Soupios says.

It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

It can be avoided if human values are translated into their language.

In a study last year, of all people surveyed, 48 percent said they wanted to ride in one, while 50 percent did notThe fact that attitudes toward self-driving cars appear to be so steady across generations suggests how transformative the shift to driverless cars could be.

I think what Aesop was suggesting is that when you offer a good turn to another human being, one can hope that that good deed will come back and sort of pay a profit to you, the doer of the good deed.

I mean, there are some cautious steps I can take, but ultimately I can not guarantee myself that.

I can not control whether or not I wind up getting the disease swine flu, for example, he says.

I can no longer ignore that risk.

Families can look a bit more for where the residents are going to be happy, Dr.Sloane said.

Easy-going people can also live a relatively long life.

Does assisted living really mark a great improvement over a nursing home, or has the industry simply hired better interior designers? Are nursing homes as bad as people fear, or is that an out-moded stereotype ( ' , 固定 看法 )? Can doing one's homework really steer families to the best places? It is genuinely hard to know.

But if we come up with an answer, robots could be good for humanity.

As artificial intelligence ( ' , AI) becomes increasingly sophisticated, there are growing concerns that robots could become a threat.

And involving the future resident in the process can be very important.

After a point, countries can become so dangerous that food relief workers are no longer safe and their programs are halted.

A reasonable assumption—don't families struggle to avoid nursing homes and suffer real guilt if they can't? In the initial results, assisted living residents did paint the most positive picture.

You probably think college students are experts at sleeping, but parties, preparations for tests, personal problems and general stress can wreck a student’s sleep habits, which can be bad for the body and the mind.

In any case, new graduate students can learn who their advisers or temporary advisers are by visiting or emailing the departmental office and asking for the information.

How can I help you?The massive decline in sleep happened so slowly and quietly that few seemed to notice the trend.

But many tech home   remedies can be explained by a little science.

We can lead people to eat less while helping the restaurant business.

We can cultivate a growth mind-set in children by telling success stories that emphasize hard work and love of learning.

They can have some say in how much their servers earn.

These experiments indicated that a focus on effort can help resolve helplessness and generate success.

The teachers must be free to teach in their own way—the curriculum should be flexible enough so that they can use their individual talents to achieve the goals of the course.

The mastery-oriented children, on the other hand, think intelligence is not fixed and can be developed through education and hard work.

The implication is a sharp decline in global trade, which has plunged partly because oilproducing nations can't afford to import as much as they used to.

Yet there are recent signs that the gap could be starting to shrink.

White storks feed on locusts ( ' , 蝗虫) and other insects that can become pests if their numbers get out of hand.

They could buy unique souvenirs there to take back home.

They can multiply at an accelerating rate.

They can better pull through the winter.

They can be solved with better management.

There are huge clusters of organic waste they can feed on, said Flack.

The reasoning behind this saying is that low oil prices discourage investment in new production capacity, eventually shifting the oil supply curve backward and bringing prices back up as existing oil fields—which can be tapped at relatively low marginal cost—are depleted.

The cycle continues: Poorer parents have less time and fewer resources to invest in their children, which can leave children less prepared for school and work, which leads to lower earnings.

The consumer was ultimately to be mentioned as well, especially by the likes of Dorothy Shaver, who could point to the sales figures at Lord & Taylor.

The birds can easily eat pieces of plastic or rubber hands and they can die, said Flack.

The International Monetary Fund calculates that countries can generate substantial fiscal revenues by eliminating fossil fuel subsidies and levying carbon charges that capture the domestic damage caused by emissions.

Students use forums to chat, play games, and solve problems together at no cost, or they can pay a few hundred dollars to take courses with trained teachers.

Some are pricey—a three-week intensive program can cost $4,500 or more—but most offer scholarships.

Progress in the development of renewables could be fragile, however, if fossil fuel prices remain low for long.

Participation grows through friends and networks and if you realize that's how they're growing, you can start to take action and bring in other students, he said.

Parents who are white, wealthy or college-educated say too much involvement can be bad.

Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies.

Most people would love to get students from more underserved populations, but they just can't get them in the door.

Moreover, nonparticipation by nations, if sufficiently widespread, can undermine the political will of participating countries to act.

Migrating birds affect ecosystems both at home and at their winter destinations, and disrupting the traditional routes could have unexpected side effects.

Funding agencies note that data paid for with public money should be public information, and the scientific community is recognizing that data can now be shared digitally in ways that were not possible before.

Even people whose data are less popular can benefit.

Early childhood experiences can be very consequential for children's long-term social, emotional and cognitive development, said Sean Reardon, professor of poverty and inequality in education at Stanford University.

Different upbringings set children on different paths and can deepen socioeconomic divisions, especially because education is strongly linked to earnings.

Could utility alone justify the new ideas of the American designers? Fashion is often regarded as a pursuit of beauty, and some cherished fashion's trivial relationship to the fine arts.

By making the effort to organize and label files so others can understand them, scientists become more organized and better disciplined themselves, thus avoiding confusion later on.

Addressing differences in the earliest years, it seems, could reduce inequality in the next generation.

About 80% of our company's year-over-year declines in comparable sales can be attributed to shortfalls ( ' , 短缺) in cold-weather goods, said chief executive Terry Lundgren in a press release.

The don’ts can be self-fulfilling because your mind response to pictures.

In an era of instant information, shoppers can use their mobile phones to find deals.

However, today is a new era in which taking antibiotics can cause some very dangerous and potentially life threatening situations.

Can you tell us how you first became interested in this subject matter?( ' , 9 ) Wh e n f a c i n g a n e w situation, some people tend to rehearse their defeat by spending too much time anticipating the worst.

What can be done about mass unemployment? All the wise heads agree: there're no quick or easy answers.

We believe negotiation could work.

Those dangers can be addressed with farmer and consumer education, he said, while the free water and nutrients from human waste can help urban farmers in developing countries to escape poverty.

This proposal could save Medicare more than $100 billion over the next decade.

They can easily see through the businesses' tricks.

They can be dealt with through education.

They can be addressed by improved sanitation.

There're steps we can take that would make some difference, and Mayor Rahm Emanuel is trying some of them—yet the union is resisting.

The stimulus package provided money to convert the inefficient, paper-driven medical system to electronic records that can be easily viewed and transmitted.

The idea is that we are taking more out of what you might call the planet's environmental bank balance than it can sustain; we are living beyond our ecological means.

The bills in both chambers would create health insurance exchanges on which small businesses and individuals could choose from an array of private plans and possibly a public option.

Television advertising could do with a boost.

Saying that there're no easy answers sounds wise, but it's actually foolish: our unemployment crisis could be cured very quickly if we had the intellectual clarity and political will to act.

No other manufacturer can produce anything like it.

More than 80% of those cases can be attributed to contact with contaminated water and a lack of proper sanitation.

Many contemporary ideas about kitchen design can be traced back to another American, Christine Frederick, who set about enhancing the efficiency of the housewife.

It's kind of a Wild West, anybody can claim themselves to be green.

In theory, interactive advertising can engage viewers in a way that 30-second spots do not.

In cases where sewage mud is used, expensive chemical fertilizer use can be avoided.

If private plans demanded similar productivity savings from providers, and refused to let providers shift additional costs to them, the savings could be much larger.

But could Norway keep its standard of living and yet cut its emissions to Moroccan or even Ethiopian levels? That question, repeated across a dozen environmental issues and across our diverse planet, is what will ultimately determine whether the human race is living beyond its ecological means as it pursues economic revival.

Anything produced in the West can be labeled green.

Another, discussing national politics, said, I feel like one person can't do that much, and I get the impression most people don't think a group of people can do that much.

A place where women could work more efficiently.

A place where high technology could be applied.

A case can be made that rich nations export environmental problems, the most graphic example being climate change.

The negative impacts of natural disasters can be seen everywhere.

Researchers at Duke University scrutinized more than 160 published studies and found an absence of strong evidence that any of these approaches can make a big difference.

Now, a new study that began with about 1,000 children in New Zealand has tracked how a child’s low self-control can predict poor health, money troubles and even a criminal record in their adult years.

But now Israeli researchers are reporting that even sleeping in the same room can have negative consequences: not for the child,but for the mother.

A new study has failed to find any conclusive evidence that lifestyle changes can prevent cognitive decline in older adults.

You can see that we're here to stay, said Vladimir Cheberdak, 57, chief of the Bellingshausen Station, as he sipped tea under a portrait of Fabian Gottlieb von Bellingshausen, a high-ranking officer in the Imperial Russian Navy who explored the Antarctic coast in 1820.

University education is becoming attractive to students who can afford it.

Their behaviors can be found in almost all teenagers on earth.

Their behaviors can be an invisible threat to society.

The Paris agreement has been widely hailed as a positive step forward in addressing climate change for all, although the details on addressing climate justice can be best described as sketchy.

That is bad news for any firm that may hope that smartwatches can make up ground for maturing smartphone and tablet markets.

That could be another explanation for why companies seem to be strengthening their talk of the practicality of their devices.

So what other variables could be used if the racial concept is thrown out? Yudell said scientists need to get more specific with their language, perhaps using terms like ancestry or population that might more precisely reflect the relationship between humans and their genes, on both the individual and population level.

Scholars warn that Antarctica's political drift could blur the distinction between military and civilian activities long before the continent's treaties come up for renegotiation, especially in parts of Antarctica that are ideal for intercepting ( ' , 拦截) signals from satellites or retasking satellite systems, potentially enhancing global electronic intelligence operations.

Mental problems can now be found in large numbers of teenagers.

It is still easy to be dazzled by the display of drones ( ' , 无人机 ), 3D printers, virtual reality goggles ( ' , 眼镜 ) and more smart devices than you could ever hope to catalog.

Having to install a different app for each smart appliance in your home is annoying; it would be nicer if you could manage everything together.

Graduates from elite universities usually can get decent jobs.

Fancy packaging can help to engage new smokers.

Essentially, I could not agree more with the authors, said Svante Pääbo, a biologist and director of the Max Planck Institute for Evolutionary Anthropology in Germany.

Beyond the Antarctic treaties, huge obstacles persist to tapping these resources, like drifting icebergs that could jeopardise offshore platforms.

Assumptions about genetic differences between people of different races could be particularly dangerous in a medical setting.

And even before then, scholars warn, the demand for resources in an energy-hungry world could raise pressure to renegotiate Antarctica's treaties, possibly allowing more commercial endeavours here well before the prohibitions against them expire.

According to the survey, that lack of enthusiasm could stem from concerns about privacy and security.

A full 18 percent have even returned devices until they feel they can get safer guarantees against having their sensitive information hacked.

You say your shop has been doing well, could you give me some idea of what doing well means in facts and figures?Birds are famous for carrying things around.

You can think of it as physical attraction.

We hope you enjoy the series about how you can make a difference by becoming a social worker.

We can’t expect kids to turn off that admiration when the same person is selling sugar.

The solution: set priorities—add up the annual cost of each item, then consider what else you could buy with the same money.

The bodies of fish and other meat eaters can build up high levels of the chemicals.

Some, like homing pigeons can be trained to deliver messages and packages.

Professor Henderson, could you give us a brief overview of what you do, where you work and your main area of research? I have many Business English students.

People who live, hunt or fish near bird coloniesneed to be careful, the researchers say, The birds don’t mean to cause harm, but the chemicals they carry can cause major problems.

Operationally, you could think intimacy as you share secrets: you share information with this person that you don’t share with anybody else.

Now what’s interesting about the theory is what do you have if you only have one out of three or two out of three? What do you have and how is it different if you have a different two out of three? What’s interesting about this kind of theorizing is it gives rise to many different combinations that can be quite interesting when you break them down and start to look at them carefully.

Now there’s a lot more evidence of how powerful a celebrity, especially a professional athlete can be in influencing children’s behavior.

It’s no surprise that high-profile athletes can influence children’s eating behaviors, but the scientists were able to quantify how prevalent these endorsements are in the children’s environment.

Few of us can fill up the tank without buying a few snacks, cigarettes, soft drinks or other items we can live without.

Even today, says the legend, the girls can be seen above the towering rock as seven shining stars in the night sky.
