Tell us your story

"China and Me, Five Years from Now"

My dad was a nice man who didn't talk very much. He used to work as a mechanic fixing army planes, but he was sent back after getting injured. Later, he opened a garage with his friend, who sold it behind his back. People took advantage of him, but he couldn't turn down a favor.

That's why I felt more than a little confused when a policeman called my office, asking me to pick him up at the station. The old man was found walking alone along the highway. When a police patrol car stopped him, he explained that he was traveling to Nebraska to claim his million dollars.

"What million dollars?" I asked Dad, who was sitting quietly in the passenger's seat as we drove home. Dad took out a wrinkled letter and read, "We are now authorized to pay one million dollars to Woodrow T. Grant of Billing, Montana. "

I never knew dad wanted to be a millionaire. I asked him what he would do with the prize money, to which he replied that he wanted a new truck. His driver's license has expired (失效) fifteen years ago when he reached his seventies.

I knew that the letter was a scam (骗局), but the old man was as stubborn as a mule. He even slept with that stupid letter in his hand. He memorized it word for word. I didn't think he could memorize anything anymore. He wouldn't stay at home either, but ventured out onto the highway again and again, until the police sent him back. In the end, I had to give up. I called in sick at work and the two of us set out in my car to claim his prize.

We traveled past several states. Dad remained silent, while I found it hard to control my temper. Finally, I decided to ask the question. "Why on earth do you need a million dollars for a stupid truck?" Dad replied, "The rest is for you. I wanted to leave you something." His words made me speechless.

The following day, we arrived at our destination. Dad's heart leaped with joy as I opened the car door for him. He marched toward the specific spot marked in the letter. However, when someone answered the door, he saw their puzzled expression. At that moment he knew that he was not a millionaire. He stood there in stunned silence as tears rolled down his cheeks.

On our way back, we stopped at a truck-dealer's. Dad cast his eyes towards his favorite truck, and then he looked at me. I realized the truth of his disappointment, so I decided to buy it for him. We drove his treasured vehicle back home with the wind in our face. Although I was tired, what I felt at that moment is something money cannot buy.

In the future, chances are we don't need to depend on human donations for life-saving skin grafts (移植).

That's the goal of Xeno Therapeutics, a biotech non-profit organization. The US Food and Drug Administration approved the group's initial application for temporary skin grafts removed from genetically modified (基因改良) pigs. This means that they can start testing pig skin grafts on people who have experienced severe burns.

Skin, the body's largest organ, plays an important role in blocking pathogens (病原体) from reaching our organs inside. It also helps the body keep a constant temperature. People with severe skin damage are at a high risk of developing deadly infections as a result of changes in temperature.

At the moment, the only skin grafts available in the US come from the dead people who have agreed to be organ donors, or patients who have gone through surgery to remove skin after large weight loss. These human skins used for grafts are not easy to find.

Xeno Therapeutics, which gets its name from animal-to-human transplants, has raised pigs that have skin remarkably similar to our own. Grafts from these pigs are therefore more likely to hide without being detected by the host's immune system — at least temporarily. The idea is that they could be used for immediate burn treatment, followed human skin graft treatment later.

"I'd say that just like comparing a Coke with Pepsi, it would be hard to tell which was the human skin and which was the pig graft," said Xeno Therapeutics CEO Paul Holzer.

The non-profit organization has been working to conduct the clinical trials, which will only be testing the grafts' safety and tolerability in six patients with severe burns. Assuming the results are positive after a month, the grafts will need to pass through two more stages of testing before they can be approved for widespread clinical use.

Several other groups around the world are working to make animal organs suitable for clinical medicine. In Brazil, researchers are exploring using tilapia skin as temporary bandages for burn victims whose skin is regrowing.

Mercury (汞), an unusual element, is poisonous and can be found just about everywhere. It can also exist as an organic compound, the most common of which is methylmercury (甲基汞). While we can take steps to avoid both elemental and inorganic mercury, it is much harder to avoid methylmercury.

Most of the mercury in the environment comes from coal-burning power plants. The concentration of mercury in the air from power plants is very low, so it is not immediately dangerous. However, the mercury is then washed out of the air by rainstorms and eventually ends up in lakes and oceans.

The mercury in the water doesn't immediately get absorbed by fish, as elemental mercury doesn't easily spread into cells. However, methylmercury spreads into cells easily, and certain bacteria in the water change the elemental mercury to methylmercury. Methylmercury in the water spreads into plankton (浮游生物). Small animals eat the plankton and absorb the methylmercury in the plankton and then large animals eat small animals and absorb the methylmercury. Because each animal passes the methylmercury much more slowly than it absorbs it, methylmercury builds up in the animal over time and is passed on to whatever animal eats it.

As people became aware of the concentration of mercury in fish, many reacted by removing seafood from their diet. Scientists have studied the effects of mercury. By determining the levels of mercury consumption that cause any of the known symptoms of mercury poisoning, they were able to identify a safe level of mercury consumption. The current recommendation is for humans to take in less than 0. 1 microgram of mercury for every kilogram of weight per day. This means that a 70-kilogram person (about 155 pounds) could safely consume 7 micrograms of mercury per day.

Nutritionists recommend that, rather than remove fish from our diet, we try to eat more of the low-mercury fish and less of the high-mercury fish. Low-mercury species tend to be smaller fish while high-mercury species tend to be the largest carnivorous (食肉的) fish. Awareness of the particulars of this problem, accompanied by mindful eating habits, will keep us on the best course for healthy eating.
