9、（寿命）that are similar to humans, living for around 50 to 70 years. Now scientists believe they know why. A team at the University of Chicago, Us has found that elephants carry a large number of genes that stop tumors（肿瘤）from developing. To be precise , t hey found 20 copies of an anti-tumor gene call

10、ed TP 53 in elephants. Most other species , h umans included, only carry one copy. According to the research, which was recently published on the online science network BioRxiv, the extra copies of the gene improved the animals sensitivity to DNA damage. This lets the cells（细胞）quickly kill themselve

11、s when damaged before they can form deadly tumors. “An increased risk of developing cancer has stood in the way of the evolution of large body sizes in many animals,” study author Dr Vincent Lynch told The Guardian. If every living cell has the same chance of becoming cancerous, large creatures with

12、 long life spans like whales and elephants should have a greater risk of developing cancer than humans and mice do. But across species, the risk of cancer does not show a connection with body mass. This phenomenon was found by Oxford University scientist Richard Peto in the 1970s and later named “Pe

13、tos paradox”. Evolutionary biologists believe it results from larger animals using protection that many smaller do not, In the elephants case, the making of TP53 is natures way of keeping this species alive. The study also found that when the same genes were brought to life in mice, they had the sam

14、e cancer resistance as elephants. This means researchers could use the discovery to develop new treatments that can help stop cancers from spreading or even developing in the first place. “Nature has already figured out how to prevent cancer,” said Joshua Schiffman, an oncologist at the School of Me

15、dicine, University of Utah, US. “Its up to us to learn how different animals tackle（对付）the problem so we can use those strategies to prevent cancer in people.” 1.

19、le jar （泡菜坛） , as I can remember, sat beside the dresser in my parents bedroom. When ready for bed, Dad would toss any coins in his pockets into the jar. As they dropped, they landed with a merry jingle. Whenever the jar was full, Dad would roll up the coins. Every time he slid the box of rolled coi

20、ns across the counter at the bank toward the cashier, he would smile proudly and say, “ All for my sons college.” We would always celebrate each deposit by stopping for an ice cream cone. Dad would show me the coins in his change, saying “When we get home, well start filling the jar again.” He alway

21、s let me drop the first coins into the empty jar. “You might have to get to college on loose change,” he said. “But youll get there.” As years passed, I went to college, got married and took a job. Once, while visiting my parents, I noticed the jar was gone. It had served its purpose. My dad was a m

22、an of few words and never lectured me on the values of determination, perseverance or faith. The jar had taught me those far better than the most flowery of words could have done.

23、each other, taking turns holding their first grandchild. When Jessica began crying, my wife Susan took her from Dads arms to put her in my parents room. Susan came back, tears in her eyes and led me into the room. “Look,” she said softly. To my amazement, there, next to the dresser, stood the old pi

24、ckle jar, as if never removed, the bottom already covered with coins. I walked over to it, dug down into my pocket, and pulled out several coins. Choked by emotion, I dropped them into the jar.

29、ight futures. But is there anything wrong with a kind of “ overparenting style”? Parental involvement has a long history of being studied. Many of the studies, conducted by Diana Baumrind, a famous psychologist at the University of California, Berkeley, have found that a good parent is the one who i

30、s involved and reacts to her child in a positive way, who sets high expectations but gives her child independence. These “authoritative parents” appear to hit the sweet spot of parental involvement and generally raise children who do better academically, psychologically and socially than children wh

31、ose parents are not strict and less involved, or controlling and more involved. Why is this parenting style so successful? Authoritative parents actually help improve motivation in their children. Carol Dweck, a social psychologist at Stanford University, has done research that indicates why authoritative parents raise more motivated children. In a typical experiment, Dr. Dweck takes young children into a room and asks them to solve a simple puzzle. Most do so with little difficulty. But then Dr. Dweck tells some, but not
