Google has kicked off Google Science Fair (GSF) 2014, its annual online competition for

bright, creative and ambitious teenagers who want to change the world with science. While the project is led by Google, it also has the backing of the Lego Group and world-famous publications National Geographic and Scientific American. The competition is open for students aged 13 to 18, who can sign-up now, form a team and begin working on a submission.

The winner will be rewarded with a ten-day exploration to the Galapagos Islands aboard the National Geographic Endeavor, as well as a VIP tour of ‘Spaceport America’ in New Mexico. Google is also throwing in a $50,000 scholarship and $10,000 for the winner’s school to purchase cutting-edge science lab equipment.

Google suggests that each project should be “an in-depth investigation of a science question or engineering problem” but otherwise, it’s up to students to pick and develop an idea that follows the competition rules.

Completed projects need to be submitted by May 12, 2014 at 11:59 PDT. Google will announce the regional competitors in June, ahead of global finalists in August and the competition winners in September.

Interested? Here are the rules.

Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of ageing as wrinkles and grey hair．But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age．In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s—much later than previously thought.

Furthermore, rather than losing many brain cells as we age, we retain them, and even produce new ones well into middle age．For years it’s been assumed that brain, much like the body, declines with age．But the longest, largest study into what happens to people as they age suggests otherwise.

This continuing research has followed 6,000 people since 1956, testing them every seven years．It has found that on average, participants performed better on cognitive(認(rèn)知的) tests in their 40s and 50s than they had done in their 20s．Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving.

Where they performed less well was number ability and perceptual speed—how fast you can push a button when ordered．However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond．In short, researchers are now coming up with scientific proof that we do get wiser with age.

Neuroscientists are also finding that we are happier with ageing．A recent US study found older people were much better at controlling and balancing their emotions．It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are sub-consciously aware that we have less time left in life: therefore, it becomes more important for us to be happy．

1.Barbara Strauch probably agrees that ______．

A．the young are better at handling important things

B．people’s brains work best between their 40s and 60s

C．a(chǎn)geing leads to the decline of the function of the brain

D．wrinkles and grey hair are the only symbols of ageing

2.The continuing research has found older people perform better on _____ .

A．vocabulary tests

B．number ability

C．perceptual speed

D．body balance

3.People are happier with age because ______.

A．they learn to value the time left

B．they know how to share feelings

C．they cannot focus on negative aspects

D．they do not realize the possible dangers

4.What is the main idea of the passage?

A．People get wiser with age．

B．People get more forgetful with age．

C．People get happier with age．

D．People get more self-aware with age．

Weighing the Options

Making decisions when shopping is often a tough call．Even if you’re satisfied with the first dress you try on, would you go on looking for alternatives, comparing styles and prices, until you literally dropped dead?

Psychology researchers have studied how people make decisions and concluded there are two basic styles．“Maximizers” like to take their time and weigh a wide range of options—sometimes every possible one—before choosing．“Satisficers” would rather be fast than thorough.

1. So even if they see what would seem to meet their requirements, they can’t make a decision until after they’ve examined every option to make sure that they’re making the best possible choice．Researchers followed 548 job-seeking college seniors at 11 schools from October through their graduation in June．They found that the maximizers landed better jobs．2.

“The maximizer is kicking himself because he can’t examine every option and at some point had to just pick something,” they say．“Maximizers make best decisions and end up feeling bad about them．3.”

Satisficers also have high standards, but they are happier than maximizers．Maximizers tend to be more depressed and to report a lower satisfaction with life, his research found.

Faced with so many choices in our lives, we need to learn how not to waste time and energy on our decision-making．

4. For instance, if you’re picking a restaurant for a lunch meeting, first deciding on a certain part of town or type of cuisine can narrow your options.

Once you’ve arrived at a decision, stick with it．5. To limit the number of options you can consider, you can set a time limit for decision-making．Say you are buying a new bag, you could spend an amount of time studying features, price and value—but if you give yourself only five minutes to make a decision, and there are only these bags you can consider, you’ll save time．You’ll be happier with your decision, too.

A．Maximizers are people who want the best.

B．First of all, decrease your range of options.

C．Comparing is often a must when you make a decision．

D．Just accept that no decision is ever completely perfect.

E．Satisficers make good decisions and end up feeling good.

F．The other is to make decisions more accurately at the beginning.

G．Their starting salaries were 20 percent higher but they felt worse about their jobs．
