Researchers at the University of Scotland have discovered a protein that can influence viruses developing and even can control cancer. Now the fight is on to fully understand how it works in the hope of turning the laboratory research into a treatment.
The protein is called Hira. Technically it is a histone(组蛋白)complex, but it is easier to understand in terms of what it can do. Three years ago Dr Taranjit Singh Rai and colleagues at the Beatson Cancer Institute and Glasgow University reported that Hira could possibly suppress the division of cells that causes cancer. In the course of that research, Dr Rai found out something unusual. In the lab they have established that the Hira protein has a role to play in the anti-viral fight, thus, making it have a fundamental role to play in fighting against cancer.
The trick in using it to fight diseases may lie in increasing Hira levels in our cells. “I think what researchers might be interested in is how we can increase levels of this protein to deal with the viruses better, Dr Rai said.
Dr Rai has led an international study and support has come from Cancer Research UK and the results are published in the journal Nucleic Acids Research. But there is a major concern that the research is still limited to the laboratory.
It is going to take some time, probably years, before this work can move out of the lab and into clinics and hospitals. But the researchers are excited Hira will one day be the basis of a new approach in medicine.

Howard Carter Finds King Tut's Tomb
Howard Carter was only 17 years old when he first went to Egypt in 1891. His father was quite successful as a portrait painter in England. Howard had a great deal of artistic talent, but he did not want to become a portrait painter like his father. He wanted adventure. With his father's help, he got a job with an archaeologist who was on his way to Egypt. This was an exciting opportunity for young Howard Carter.
In Egypt, Howard Carter worked as an artist for some of the best Egyptologists(埃及古 物学者)of his time. An Egyptologist is an archaeologist whose focus is learning about ancient Egypt. It was not long before Howard Carter was quite well known among Egyptologists, not only as an artist but also for his knowledge about ancient Egypt and archaeology.
Howard Carter wanted to hunt for King Tut's tomb, but that took men and money. Howard Carter finally got lucky. Lord Carnarvon was a very rich man. Lord Carnarvon allowed Howard Carter to hire 50 men to help him search for Tut's tomb.
In November 1922, by the light of a candle, Howard Carter cut a hole in a secret door. Lord Carnarvon and Howard Carter carefully looked through the hole. What they saw through the peephole(窥视孔)) was amazing! They could not believe their eyes! The room was filled with treasures—couches shaped like animals, jeweled chests, vases, statues, and even chariots(二轮战车),all glittering with gold. It took months to move the treasures they found in the first room alone before they could open the doors in that room that led to other rooms! In other rooms, they found the chair King Tut had used as a small child.
The tomb was an incredible discovery, not only for its monetary value but also for its history. Historians learned so much about the people who lived over 3,000 years ago, about their culture and beliefs and daily life, from the objects found in King Tut's tomb. Howard Carter became world famous.

One of my second graders, Debbie, had been unusually quiet in my Family Living class. When I asked her if something was wrong, she replied, “I don't feel like talking today. I'm sad. My best friend's parents are going to get divorced(离婚的). Her father moved out of the house. I told her I would share my dad with her, but I know it isn't the same. ”
I was surprised to learn that almost every child in my primary grade Family Living classes seemed to have some personal acquaintance (了解)with divorce—through friends of the family, neighbors, relatives, or much closer to home—their own parents. For many of them, divorce was just a normal part of life. Emily once said, “I want to be a doctor or nurse when I grow up, so after I get married and divorced, I'll be able to support myself. Then there was Billy, who stated, “When my mom gets married again next week, we're all going on a honeymoon.
Sometimes parents fight about the kids," said Kimberly. “My parents are divorced and my mom keeps pulling on one of my arms and my dad pulls the other. ” How sad, I thought, that a child would feel like her parents were actually pulling her apart because they each wanted more of her than the other should. “I hate that my parents are divorced! exclaimed Greg. “It's all my fault, too. I bite my nails too much. ”
Lori tried to look at things from a more positive perspective. “Your mother and father got mad at each other, but it doesn't mean they got mad at you," said Lori. “Lori is right," I said. Sometimes a husband and wife realize that they no longer love each other and decide it will be best for the whole family if they don't live together anymore. But that doesn't mean they stop loving their children, and it certainly doesn't mean that it is the children's fault!
“Maybe your mom and dad will change their minds and get undevoured,” Eric told Greg. “Then you can all be together again. ” Greg shook his head. “No, that won't happen. ” And then, with a thoughtful expression on his face, he said, “You know something? Divorce is like a cake. You cut it in half and it's separated forever. ”
