A recent study surveyed 5,000 British families about their experiences with volunteering and their mental health. Participants completed the same survey every two years from 1996 to 2008.

About 20 percent of the survey participants reported doing regular unpaid work Researchers found that these volunteers also scored highest on their mental health scores.The two were linked so directly that the more a person volunteered,the happier they were.

One could argue a chicken-and-egg theory: happier people are more likely to have the time,money,energy and resources to give back to others.But even when researchers adjusted for education,social class and total health,the link was there,suggesting that the mental increase came from volunteering and not the other way around.

According to Dr.Stephen G.Post,author of The Hidden Gifts of Helping,when you help others,your brain releases feel-good chemicals,which can help cells repair themselves and grow.And this translates to better health.

So volunteering can help improve both your physical and mental health—on one condition.You have to mean it. People who volunteered for "self-oriental" reasons,either because they were forced to do so for work or school or because they were trying to get away from problems in their lives,had a mortality（死亡率）risk that was similar to those who didn't volunteer at all.It was only when people were volunteering out of a true sense of sympathy that they saw any health benefits.

So whether it's arranging books at the library or walking dogs at the animal shelter,find a cause that's important to you and give it a try.Volunteering is a good way to develop a sense of connection that not only helps your community,but may also be good for you.

Scientists announced that they had found the gravitational waves（引力波）that confirmed a prediction made by Albert Einstein a century ago.The discovery,made with the Laser Interferometer Gravitational—Wave Observatory, known as LIGO,is the milestone（里程碑）in a decades—long search for signs of this phenomenon."The discovery will open a new window onto the universe,"said David Reitze,executive director of LIGO.

Since humans first watched skyward,we have relied on light of all wavelengths to describe the universe.The light that could be seen first showed the starry heavens,while infrared（红外线的）waves allowed us to see older and more distant stars.

But now,researchers will be able to sense the universe in a whole new way: with their "ears"."We can hear gravitational waves.We can hear the universe,"Gabriela Gonzalez,LIGO's spokeswoman at Louisiana State University,said."That's one of the beautiful things about this: We are not only going to be seeing the universe,we are going to be listening to it."

Gravitational waves,which Einstein predicted as part of his general theory of relativity,occur as objects accelerate or decelerate through space,much the way a boat moving on a lake sends waves across the water's surface. But they're so tiny that until now it's been nearly impossible to find them,even those caused by something as large as a planet moving around the sun.

To pick up this signal,scientists have to look for violent events in the universe.This particular signal appears to have been caused by a collision.That occurred about 1.3 billion years ago between two black holes,holding 29 and 36 solar masses（太阳质量）.

Fiona Harrison,chair of Caltesh's division of physics,mathematics and astronomy,guessed that hundreds of new events would be found over the next few years,allowing scientists to perform a range of different types of studies. "There are probably many events we haven't dreamed of and this is just the beginning,"she said.

How to improve your memory

There is no such thing as “bad memory”,and everyone can improve their memory as long as they are not suffering from loss as a medical condition.    13    

Stop thinking that you have a “bad memory”. Convince yourself that you do have a good memory that will improve.Too many people get stuck here and convince themselves that their memory is bad,that they are just not good with names and numbers just slip out of their minds for some reason.    14    

Use association(联想)to remember facts.    15    For example, if you have a hard time remembering that JKF was the president involved in the Bay of Pigs Invasion, just picture the handsome president swimming in an ocean surrounded by happy pigs.

Involve several scenes. You can stimulate(刺激)more parts of your brain by using as many senses as possible when memorizing information.    16    For example, the process of writing information by hand stimulates your brain and makes it easier to remember the information later.

    17    By developing new mental skills, especially complex ones such as learning a new language or learning to play a new musical instrument, and challenging your brain with puzzles and games, you can keep your brain active and improve its physiological(生理学上的)function.
