Fuji Fine Pix Z20fd: This sub-$200 digital camera is the perfect thing for any high school student. Available in five eye-catching colors, the Fine Pix Z20fd is a 10-megapixel(兆像素) camera. Media kids will appreciate the camera’s blog and auction mode, as well as the “one touch” movie recording option that allows them to edit movies before sharing them online. This is certainly an affordable camera for photo-lovers of any age.

2010 was the year the Earth struck back.
Earthquakes, heat waves, floods, volcanoes, super typhoons, blizzards (暴风雪), landslides and droughts killed at least a quarter million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
“It just seemed like it was back-to-back(接二连三) and it came in waves,” said Craig Fugate, who heads the US Federal Emergency Management Agency. It handled a record number of disasters in 2010.
“The term “100-year event’ really lost its meaning this year.”
And we have ourselves to blame most of the time, scientists and disaster experts say.
Even though many disasters have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and strange year for everything from wild weather to earthquakes.
Poor construction and development practices make earthquakes more deadly than they need be. More people live in poverty in vulnerable buildings（危房） in crowded cities. That means that when the ground shakes, the river floods, or the tropical cyclone hits, more people die.
Disasters from the Earth, such as earthquakes and volcanoes “are pretty much constant,” said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. “All the change that’s made is man-made.”
The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people – many of them living in poverty- and more poorly built shanties(棚户区) ,than it did 25 years ago. So had the same quake hit in 1985 instead of 2010; total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
Climate scientists say Earth’s climate also is changing thanks to man-made global warming, bringing extreme weather, such as heat waves and flooding.
The excessive(过多的) amount of extreme weather that dominated 2010 is a classic sign of man-made global warming that climate scientists have long warned about. They calculate that the killer Russian heat wave – setting a national record of 111 degrees – would happen once every 100,000 years without global warming.
Data show that 18 countries broke their records for the hottest day ever.
“The Earth strikes back in response to bad human decision-making,” said Debarati Guha Sapir.” “It’s almost as if the policies, the government policies and development policies, are helping the Earth strike back instead of protecting from it. We’ve created conditions where the slightest thing the Earth does is really going to have a surprising impact.” White House science adviser John Holdren said we should get used to climate disasters or do something about global warming. “The science is clear that we can expect more and more of these kinds of damaging events unless and until society has sharply reduced the amount of heat-trapping gases and particles(颗粒).”

Catch yourself daydreaming while washing the dishes again? If this happens often you probably have a pretty capable working memory and a sharper brain, new research suggests.
This mind wandering, it seems, actually gives your working memory a workout. Working memory is the mental work space that allows the brain to juggle multiple thoughts at the same time. The more working memory a person has, the more daydreaming they can do without forgetting the task at hand.
Researchers studied groups of people from the University of Wisconsin－Madison community, ranging in age from 18 to 65. The volunteers were asked to perform simple tasks, like pressing a button every time they took a breath or clicking in response to a letter popping up on a computer screen; these tasks were so easy that their minds were likely to wander, the researchers figured.
The researchers checked in periodically, asking the participants if their minds were on task or wandering. When the task was over, they measured each participant's working memory capacity by having them remember letters while doing math questions. Though all participants performed well on the task, the researchers noticed that the individuals who indicated their minds had wandered more than others also scored higher on the working memory test.
“What this study seems to suggest is that, when circumstances for the task aren't very difficult, people who have additional working memory resources allocate them to think about things other than what they're doing，” said Jonathan Smallwood, a study researcher of the Max Planck Institute for Human Cognitve and Brain Science.
When our minds run out of working memory, these off－topic thoughts can take the main stage without us consciously meaning them to; for instance, arriving at home with no memory of the actual trip, or suddenly realizing that they've turned several pages in a book without understanding any of the words.
“It's almost like your attention was so absorbed in the mind wandering that there wasn't any left over to remember your goal to read，” study researcher Daniel Levinson, said in a statement.
People with overall higher working memory were better able to stay focused when the task at hand required it. Those who had low working memory often had their thoughts drift away from the task, and did less well at it.
The findings add to past research suggesting these mind drifts can be positive moments. For instance, daydreaming has often been associated with creativity—researchers think that our most creative and inventive moments come when daydreaming. It's likely that the most intelligent among us also have high levels of working memory, Levinson noted.

If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing:"Busy!""Crazy busy!".It is,pretty obviously,a boast disguised as a complaint. And the common response is a kind of congratulation:"That's a good problem to have,"or"Better than the opposite."
Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are.What those people are is not busy but tired.Exhausted!Dead on their feet.It's almost always people whose busyness is purely self-imposed:work and obligations they've taken on voluntarily,classes and activities they've "encouraged" their kids to participate in.They're busy because of their own ambition or drive or anxiety,because they're addicted to busyness and dread that they might have to face in its absence.
Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work.It's something they have chosen.Busyness serves as a kind of existential reassurance(令人安心的保证），a measure against emptiness,obviously your life cannot possibly be silly or tiny or meaningless if you are so busy,completely booked,in demand every hour of the day.
Idleness is not just a vacation.It is as necessary to the brain as vitamin D is to the body,and deprived of it we suffer a mental affliction as ugly as rickets.The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole,for making unexpected connections and waiting for the wild summer lightning strikes of inspiration."Idle dreaming is often the essence of what we do,"wrote Thomas Pynchon.Archimedes' "Eureka"in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.
