    I am Peter Hodes, a volunteer stem courier. Since March 2012, I've done 89 trips of those, 51 have been abroad, I have 42 hours to carry stem cells(干细胞) in my little box because I've got two ice packs and that's how long they last, in all, from the time the stem cells are harvested from a donor(捐献者) to the time they can be implanted in the patient, we've got 72 hours at most, So I am always conscious of time.

    I had one trip last year where I was caught by a hurricane in America. I picked up the stem cells in Providence, Rhode Island, and was meant to fly to Washington then back to London. But when I arrived at the check-in desk at Providence, the lady on the desk said: “Well, I'm really sorry, I've got some bad news for you-there are no fights from Washington.” So I took my box and put it on the desk and I said: “In this box are some stem cells that are urgently needed for a patient-please, please, you've got to get me back to the United Kingdom.” She just dropped everything. She arranged for a flight on a small plane to be held for mere-routed(改道) me through Newark and got me back to the UK even earlier than originally scheduled.

    For this courier job, you're consciously aware than that box you're got something that is potentially going to save somebody's life.

Dear Dad,

    Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.

    You'll soon be 84 years old, Dad, and you and I will have had 55 Father's Days together. I haven't always been with you on Father's Day but I've always been with you in my heart.

    You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.

    The Father-Daughter Duel shifted into high gear ( 档位) when you taught me to drive the old Dodge and I decided I would drive the Chevy whether you liked it or not. The police officer who sent me home, after you reported the Chevy stolen, didn't have much tolerance for a stubborn 16 year old, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.

    Our relationship greatly improved when I married a man you liked, and things really turned around when we began making babies right and left. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.

    But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn't immediately occur to me that it was you because the man driving looked so elderly and fragile behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.

    I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking. It's about loving someone more than words can say, and it's wishing that never had to end.

    I love you, Dad.

Love,

Jenny

    It's surprising how much simple movements of the body can affect the way we think. Using expansive gestures with open arms makes us feel more powerful, crossing your arms makes you more determined and lying down can bring more insights(领悟).

    So if moving the body can have these effects, what about the clothes we wear? We're all well aware of how dressing up in different ways can make us feel more attractive, sporty or professional, depending on the clothes we wear, but can the clothes actually change cognitive (认知的) performance or is it just a feeling?

    Adam and Galinsky tested the effect of simply wearing a white lab coat on people's powers of attention. The idea is that white coats are associated with scientists, who are in turn thought to have close attention to detail.

    What they found was that people wearing white coats performed better than those who weren't. Indeed, they made only half as many errors as those wearing their own clothes on the Stroop Test (one way of measuring attention). The researchers call the effect “enclothed cognition,” suggesting that all manner of different clothes probably affect our cognition in many different ways.

    This opens the way for all sorts of clothes-based experiments. Is the writer who wears a fedora more creative? Is the psychologist wearing little round glasses and smoking a cigar more insightful? Does a chef's hat make the resultant food taste better?

    From now on I will only be editing articles for PsyBlog while wearing a white coat to help keep the typing error count low. Hopefully you will be doing your part by reading PsyBlog in a cap and gown (学位服).

    The ocean bottom, a region nearly 2.5 times greater than the total land area of the earth, is even today largely unexplored. Until about a century ago, the deep ocean floor was completely inaccessible and hidden beneath waters averaging over 3,600 meters deep. Totally without light and in the case of intense pressures hundreds of times greater than at the earth's surface, the deep-ocean bottom is a strange environment to humans, in some way, as fighting and remote as the outer space.

Although researchers have taken samples of deep-ocean rocks for over a century, the first detailed global study of the ocean bottom did not actually start until 1969, with the beginning of the National Science Foundation's Deep Sea Drilling Project(DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill very deep waters, taking samples of rocks from the ocean floor.

    The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, it sailed 600,000 kilometers and took almost 20,000 samples of rocks around the world. Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger's voyages, nearly all earth scientists agree on the theories of plate tectonics (构造学) and continental drift that explain many of the geological processes.

    The sample of rocks drilled by the Glomar Challenger has also provided a climatic record stretching back hundreds of millions of years. The information of past climatic change can be used to predict the future climate.

Start of Summer, the 7th term of the year, begins on May 6 and ends on May 20 this year. It signals the transition of seasons. Here are four things to learn about it.

Greeting Start ofSummer

The term Start of Summer originated at the end of the Warring States Period. Since it is a crucial time for the harvest of summer crops, ancient Chinese emperors in different dynasties attached great importance to the Start of Summer.

CheckingOne'sWeight

The custom of weighing people at the Start of Summer originated from the Three Kingdoms Period and prevails in South China today. It was believed this practice would bring health and good luck to the people weighed. It is said those who were weighed would stay healthy in the hot summer and those who weren't would suffer illness.

EatingEggs

In ancient China, people believed a round egg symbolized a happy life and eating eggs on the day of Start of Summer was a prayer for good health. They put leftover tea into boiled water together with eggs. Later people improved cooking methods and added spices to the eggs to make them taste delicious. Today tea egg has become a traditional snack in China.

Taking Care of theHeart

According to Chinese traditional medicine, Start of Summer is a key time to moisten the heart. When the weather grows hotter, dampness and heat can affect human health. Food rich in vitamins and cool in nature is highly recommended. Vegetables, such as cucumber, tomato, and watercress and fruits like watermelon, pear and strawberry are top recommendations.
