Today, the world's diversity (多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.

    There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!

    The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world's seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.

    Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault (斯瓦尔巴全球种子库). Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.

    Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth more than it cost.”

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple — eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so-called similarity attraction theory — where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble (咬), while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions (交易) from the start.”

    Harley Street psychologist Dr. Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    To personal trainer Sammy Callari, 13-year-old Parker Seward is more than a client(客户). He's his "little brother". Over the past year, the pair have bonded. They play basketball together, share meals and dance to hip-hop like no one's watching.

    The trainer was asked to work with the 13-year-old boy, who has Down syndrome(唐氏症), because his coworker who dealt with the boy was out of town last spring. Callari had never worked with someone with a disability before. He was anxious the first day he met Parker. But Parker's big smile and cheery introduction immediately put him at ease. He reminded Callari of himself when he was a teenager. Like Parker, Callari has also faced his fair share of challenges over the years.

    As a high schooler, Callari described himself as being the weak kid. When it came to sports, he was always overlooked. His dream of playing baseball in college quickly faded away. When he went to college, Callari turned to a new sport. His younger brother trained him to become a boxer. Callari participated in five matches. Out of four of those fights he was the underdog, and he won three times. "I know how it feels," Callari said. "Society tells you that you can't do this, you can't do that." When it comes to Parker, Callari refuses to accept the word "can't".

    The friends meet twice a week to train. They bike, box, run and work on their core with push-ups. Parker has a short attention span, so it's Callari's job to keep him focused. "If Parker can do it, if he's having fun, even with his frustration, then people will ask, "Why can't I do that?" Callari said. "That's the whole task right now."

    Callari recalls Parker's mom once thanking him for taking a "chance" on her son. Callari told her he never viewed it that way. Parker may be the student, but Callari says he's also the one who's learning.

    Despite what so many people would love to believe，NASA hasn't discovered any evidence of past or present intelligent life on Mars. Therefore, when the Curiosity rover  (好奇号探测器)found something suspicious on the Red Planet's surface, they were not only surprised but also a little bit worried.

    The thin fragment (碎片)was suspicious enough to guarantee its own name, with NASA's Curiosity rover team calling it the “Pettegrove Point Foreign Object Debris，” named for where it was discovered. With no idea what it was or where it came from, the rover's handlers began to worry that it might actually be a piece of the rover itself，suggesting some unseen damage or other issue with the robot. Thankfully，those concerns seem to have been unfound.

    In a new update from NASA the object has now been identified as a natural piece of rock rather than a piece of any man-made craft or vehicle. The team analyzed the unusual object with a tool called the Chem Cam RMI. The instrument uses a laser (激光器)to sniff out the makeup of anything that is pointed at, and the results for this particular piece of debris revealed that it's actually just a very thin piece of rock.

    NASA describes the inspection: The planning day began with an interesting result from the previous plan's Chem Cam RMI analysis of a target that was referred to as “Pettegrove Point Foreign Object Debris”(PPFOD)，and supposed to be a piece of spacecraft debris fact. In fact it was found to be a very thin slice of rock, so we can all rest easy tonight. Curiosity has not begun to shed its skin!

    How this particularly thin sliver of rock got to where it is—and why it seems to be a different colour than the surrounding sand and debris—remains unexplained, but at least the rover isn't falling apart.

    LaVonn was helping out in her dad's store when a little boy, about five or six years old, came in. He was wearing a brown and oversized coat with dirty, old clothes beneath it. His shoes were broken, and only one had lace (鞋带). The boy looked around the store, picked up several items, examined them one by one and then carefully put them back on the shelf.

    LaVonn's dad walked over to the child and asked if he could help. The little boy said, "I'm looking for a gift for my brother." After 20 minutes, the child picked up a toy airplane. He held it carefully in his hands as if it were made of glass and carried it to LaVonn's father.

    "How much is this?" he asked. "My brother loves airplanes." LaVonn's dad answered, "How much money do you have?" The little boy reached into his coat and pulled out some small change (零钱). He spread his money out on the table and began to count. "I have twenty-seven cents," he answered. Her dad picked up the coins and said, "The airplane costs exactly twenty-seven cents! Wait here and I'll pack it up for you."

    The little boy walked out of the store with the gift and a smile of total satisfaction on his face. LaVonn made her way back to the shelf and she found the plane was priced at $11.98.She never mentioned it to her father. Her father didn't say anything more about it either, but she realized later, "My best gift that Christmas was seeing my dad's love in action."
