    Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mice's genes are so similar to humans', their findings could lead to the treatment of more genetic diseases.

    Scientists at the University of California, Davis studied information from a data bank of mice's genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.

    Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.

    "This is extremely valuable for people with hereditary eye disease," said researcher Professor Ala Moshiri. "All researchers are going to start using these data. In the past, we knew the problem was there but we didn't know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable." Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby's parents!

    Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice's genes to those of patients.

(1)、How many hereditary-sight-loss-related genes were newly found?
A、86. B、261. C、300. D、347.
(2)、Why is the percentage of genetic eye problems mentioned in paragraph 3?
A、To show the significance of studying mice's genes. B、To prove mice's genes are similar to humans'. C、To warn the high risk level of suffering them. D、To explain how common they are among people.
(3)、What should scientists do first to unlock secrets of genetic blindness?
A、Compare humans' genes with mice's. B、Recognize each gene's role of humans. C、Set apart a gene of a mouse each time. D、Figure out each gene's function of a mouse.
(4)、What can be a suitable title for the text?
A、New Ways to Cure Sight Loss B、Genes Found Behind Eye Problems C、Genetic Diseases Discovered in Mice D、Humans Genes Causing Eye Diseases

He graduated from high school in 2006 and was accepted at the University of Southern California to study film. But he put it off —why study movies when you can star in them.

    Scientists around the world are striving for effective detection of cancer in the early stages,which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body,and a Chinese scientist may have found a quick way of knowing whether malignant tumors(恶性肿瘤)exist in a patient's body,with just one drop of blood.

    Malignant tumors in early phases can be cured.However,it's extremely difficult to be aware of cancer in its early stages,as patients don't show obvious symptoms and thus it can only be found in its later stages,which is already too late,so to detect cancer early remains a global challenge for scientists.

    Back in 1989,scientists have found a kind of heat shock proteins (HSP),named Hsp90α,which existed in human bodies and can be used as a cancer biomarker detection kit.Scientists around the globe have been working on it since then,and more than 10,000 journals have been published on accredited magazines,yet no one has actually turned their research results into medical products.

    However,Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code,after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins.The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood.This means they are able to "create" the protein,in any quantity,and at any time they wish to.

    The kit has since been used in clinical trials involving 2,347 patients at eight hospitals in China.It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer,and it succeeded. Now,the kit has been approved to enter the Chinese and European markets,24 years after Hsp90α was discovered.

    How's your happiness quotient (指数)? Science tells us that if you want to increase your "happiness quotient" every day, it's important to take time and accept the present blessings (恩赐) in your life.

    I wanted to share a moment of feeling about some of my blessings and what's in my life to be grateful for as Thanksgiving approaches.

    One of our family traditions at our Thanksgiving meal is to go around the table and to let each one share something we're especially thankful for.

    I'm going to recite lots of things, including that I'm grateful for my health, my loving husband, and the wonderful relationship we share. My husband joins me for 3-mile walk to start our day. The exercise habit keeps our moods in check and the ups and downs of life easier to manage. We talk as we walk, sharing ideas, worries and good feelings too. Sometimes we argue a little until we figure out what to do. We always come up with something. What a blessing that is!

    It is so much to be grateful for. I feel I am the luckiest woman alive. It's my wish for you that you'll be able to spot something in your life. I hope yet you will savor (体味) and appreciate it.

    Many of us spend the holiday with our aging parents or other loved ones. In my work at AgthgParents.com, we just reminded everyone that you never know if there will be another Thanksgiving with these loved ones. We can't take the day for granted. Just be in the moment. We suggest that you verbally give thanks to your parents, no matter what conditions your aging parents may be in now. Do what you can to be tuned in to what you need as well as what your family needs.
