10、nes.“There really is a difference in brains that results in a more symmetric (对称的) brain in lefthanders，where the two sides are more equal，” said Daniel Geschwind，who led the research team.In the effort to understand how the brain shapes the mind，researchers have been trying to document the way gene

11、s and environment affect intelligence and mental abilities.They found that rightor lefthandedness is determined by genes.If a person has the gene for righthandedness，that person will be righthanded.People who do not have that gene，however，can be either left or righthanded.There is no specific gene f

12、or lefthandedness.Righthanders typically have larger left brains，where their language abilities are concentrated.Conversely，lefthanders have more balanced brains.The language abilities of lefthanders more often are concentrated on the right side.The UCLA researchers conducted brain scans on 72 pairs

13、 of male identical twins (同卵双胞胎) between 75 and 85 years old.They noticed that if identical twins carry the gene for hand preference，both must be righthanded.If they lack the gene，one twin can develop righthanded while the other can develop lefthanded.The researchers found that the brains of identic

14、al righthanded twins were very similar in size and structure.But when a lefthander was part of the twin set，the brains were different.The conclusion is that the absence of the gene for hand preference allows the brain to develop differently as the individual grows up，researchers said.【语篇解读】美国加州大学洛杉矶

22、d to 211Magalhaes team wanted to understand how the bowhead can live so long.To study this，the experts analyzed the animals complete set of genes，called its genome (基因组)The team also compared the whales genome to that of humans，mice and cows.The scientists discovered differences，including mutations

23、(突变)，in the whales genes.Those changes are linked to cancer，ageing and cell growth.The results suggest that the whales are better than humans at repairing their DNA.Thats important because damaged or flawed DNA can lead to diseases，including some cancers.Bowhead whales are also better at keeping abn
