Article: Chinese scientists have found a new way to use cells found in human urine that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells that can grow into multi-functional nerve and brain cells. The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders. Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial cells in urine into NPCs. These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said. "These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient". Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said. Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases." "It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
Answer: Chinese scientists succeeded in making NPCs from human urine.

Article: Dad was always full of advice, but one of the biggest lessons he taught me one summer was about having a strong work ethic . When my brother and I were growing up, we mowed yards during the summer to earn pocket change. Dad was our salesman. He told our neighbors about our service and offered a price they could not refuse. My brother and I got $ 10 per yard. I later found out that our friends were charging $ 20 or more for the same amount of work. Every time we headed out to mow lawns , Dad was there to watch. I used to wonder why he came with us. He stood supervising our work in the heat when he could have been inside relaxing with air conditioning and an icy drink. One day we were cutting our next-door neighbor's yard, he always waited until the grass was knee-high to call us over. To make matters worse, we had an old lawn mower. This particular afternoon, I was finishing up and was tired and sweaty. I was just about to cut off the lawn mower when I saw Dad pointing to one piece of grass. He yelled, "You missed a piece." I frowned, hoping he would let it slide and let me go home. He kept pointing. So, tired and disappointed, I went back to cut that piece of grass. I said to myself, "That one piece isn't hurting anyone. Why won't he just let it go?" But when I reached adulthood, I understood his message ---When you're running a business, the work you do says a great deal about you. If you want to be seen as an entrepreneur with honesty, you must deliver a quality product. That single blade of grass meant the job was not done. Other neighbors took notice of the good work we did and we soon got more business. We started out with one client, but by the end of the summer we had five.
Answer: They mowed it carefully.
