A sense of humor is something highly valued. A person who has a great sense of humor is often considered to be happy and socially confident. However, humor is a double-edged sword. Sometimes it can damage self-respect and annoy others.

    People who use bonding humor tell jokes and generally lighten the mood. They're thought to be good at reducing the tension in uncomfortable situations. They often make fun of their common experiences, and sometimes they may even laugh off their own misfortunes. The basic message they deliver is: We're all alike, we find the same things funny, and we're all in this together.

    Put-down humor, on the other hand, is an aggressive type of humor used to criticize others through teasing. When it's aimed against politicians, as it often is, it's extremely funny and mostly harmless. But in the real world, it may have a harmful effect. An example of such humor is telling friends an embarrassing story about another friend. When challenged about their teasing, the put-down jokers might claim that they are "just kidding," thus allowing themselves to avoid responsibility. This type of humor, though considered by some people to be socially acceptable, may hurt the feelings of the one being teased and thus have a bad effect on personal relationships.

    Finally, in hate-me humor, the joker is the target of the joke for the amusement of others. This type of humor was used by comedians John Belushi and Chris Farley—both of whom suffered for their success in show business. A small amount of such humor is charming, but routinely offering oneself up to be embarrassed destroys one's self-esteem, and fosters depression and anxiety.

    So it seems that being funny isn't necessarily an indicator of good social skills and well-being. In certain cases, it may actually have a negative effect on interpersonal relationships.

    Some people seem to have extraordinary memories. Zheng Aiqiang, a "memory athlete" on TV show Super Brain, can remember 2,660 numbers in just one hour!

    You would think people like this have special brains. But according to a recent study by researchers from the US and the Netherlands, the brain structures of ordinary people and 23 of the world's leading memory athletes show no difference.

    That's because good memories can be trained. New research in the journal Neuron(神经元期刊) suggests that you can become a super memorizer with just six weeks of hard training.

    Researchers found that technique(技巧) called loci, invented by ancient Greeks, can greatly help improve memory. By using loci, you are using your imagination to improve the brain's memory networks. You can link(关联) something you need to remember with a place that you know very well. For example, to remember a list of numbers, imagine yourself walking through your house. Each thing is linked to a number. For example, zero could be handle(把手) on the door and five could be the painting on the wall.

    In one study, some ordinary people were given 20 minutes to remember 72 words. First they could only remember 26 of them. But when they were taught loci, they could remember 62 words.

    "Not everyone can become a memory champion. But everyone using the technique can improve a lot from the level they're at," said Boris Konrad, one of the researchers in the study.

Seeds on Ice

    Close to the North Pole, remote and rocky Plateau Mountain in the Norwegian archipelago of Svalbard seems an unlikely spot for any global effort to safeguard agriculture. In this cold and deserted environment, no grains, no gardens, no trees can grow. Yet at the end of a 130-meter-long tunnel cut out of solid stone is a room filled with humanity's most precious treasure, the largest and most diverse seed collection—more than a half-billion seeds.

    A quiet rescue mission is under way. With growing evidence that unchecked climate change-will seriously affect food production and threaten the diversity （多样性） of crops around the world, the Svalbard Global Seed Vault （地窖） represents a major step towards ensuring the preservation （贮藏） of hundreds of thousands of crop varieties. This is a seed collection, but more importantly, it is a collection of the traits found within the seeds: the genes that give one variety resistance to a particular pest and another variety tolerance for hot, dry weather.

    Few people will ever see or come into contact with the contents of this vault. In sealed boxes, behind multiple locked doors, monitored by electronic security systems, enveloped in below—zero temperatures, and surrounded by tons of rock, hundreds of millions of seeds are protected in their mountain fortress. Frozen in such conditions inside the mountain, seeds of most major crops will remain viable for hundreds of years, or longer. Seeds of some are capable of retaining （保留） their ability to grow for thousands of years.

    Everyone can look back now and say that the Seed Vault was a good and obvious idea, and that of course the Norwegian government should have approved and funded it. But back in 2004, when the Seed Vault was proposed, it was viewed as a crazy, impractical, and expensive idea.

    We knew that nothing would provide a definite guarantee. But we were tired, fed up, and frankly scared of the steady, greater losses of crop diversity. The Seed Vault was built by optimists who wanted to do something to preserve options so that humanity and its crops might be better prepared for change. If it simply resupplied seed gene banks with samples those gene banks had lost, this would repay our efforts.

    The Seed Vault is about hope and commitment-about what can be done if countries come together and work cooperatively to accomplish something significant, long-lasting, and worthy of who we are and wish to be.

    Every time a new year is coming, people set out to better themselves. They promise they will lose weight, find a new job, or maybe even take that vacation they've always talked about. But why do we make these promises to ourselves, and where did this tradition come from? Why does this tradition live on when so many people fail to keep the resolutions(决定) they made? Well, we can start by blaming the ancient Babylonians.

    Around 4, 000 years ago in Babylon, the earliest recorded celebration honoring the coming of a new year was held. Calendars weren't as they are today, so the Babylonians did it in late March during the first new moon after the Spring Equinox(春分). The festivities were meant for the rebirth of the sun god, but the Babylonians made promises in order to please their gods. They felt this would help them start the new year off well.

    Resolutions continued on with the Romans. When the early Roman calendar no longer synced(同步) up with the sun, Julius Caesar decided to make a change. He consulted with the best astronomers and mathematicians of the time and introduced the Julian calendar, which more closely represents the modern calendar we use today. Caesar declared January 1 the first day of the year to honor the god of new beginnings, Janus. The Romans celebrated the New Year by offering sacrifices to Janus.

To this day, the traditions of the ancient Babylonians and Romans continue around the world. So much that Google launched a Resolution Map in 2013 where people could add resolutions and see others adding theirs in real time. However, no matter how many people participated in Google's project, the numbers are bleak when it comes to the number of people who maintain their resolutions—-only eight percent of people are successful in sticking them out.
