　　We believe every kid deserves a childhood.The opportunity to be a kid.Sunshine in dark days.That’s why we’ve partnered with The Sunshine Kids?.

　　The non-profit Sunshine Kids? established in 1982, is committed to bringing sunshine to young cancer patients’ lives by providing positive group activities and emotional support, helping them do what kids are supposed to do—have fun and celebrate life.The foundation provides a variety of free programs and events for kids receiving cancer treatments in hospitals across North America.

　　Each year Berkshire Hathaway HomeServices network members raise $2 million+ through a wide variety of fundraisers and community events, and through ticket sales and contributions made at our annual Sales Convention.

　　The Sunshine Kids? and Berkshire Hathaway HomeServices look forward to the day when the Foundation will no longer need to exist. But until that day, both organizations remain dedicated to the cause.

　　Talk to your Berkshire Hathaway HomeServices agent to see how you can bring sunshine into the lives of young cancer patients.

　　Researchers around the world interested in uncovering complex human disorders, such as Alzheimer’s disease, could soon have access to cloned monkeys with genomes that have been edited to display these conditions in China.

　　On 24 January, scientists at the Institute of Neuroscience (ION) in Shanghai reported that they had used gene-editing to disable a gene in monkeys that is crucial to their sleep- wake cycle.The scientists then cloned one of those monkeys to produce five primates (灵 长目动物)with almost identical (相同的) genes.It is the first time that researchers have cloned a gene-edited monkey.

　　Primates are the best animal model for studying higher cognitive (认知的)functions and brain disorders in humans, says neuroscientist Mu-ming Poo, ION’S director and co-founder of the new 720 million yuan (US$106 million) centre.The advantage of creating cloned monkeys is that it reduces the number of animals needed for certain types of experiments, such as testing whether a drug works.

　　But some scientists think that experiments using monkeys should be a last approach because of their higher levels of cognition.Mitchell Lazar, who studies metabolic disease at the University of Pennsylvania, says that some experiments in mice—for example, research into the genes behind human diseases—are equally appropriate scientifically as in primates.Research in mice is also more accepted by the public, and the animals are cheaper and quicker to produce.Lazar worries that if scientists have ready access to populations of gene-edited monkeys, they might use them for experiments when rodents (啮齿动物)would do.

　　Poo says that mice are not a good substitute for studying higher cognitive functions and brain disorders in humans.He argues that cloning will reduce the burden on monkeys by cutting the number used in labs.The ION follows strict international guidelines for animal research, he says.

　　Poo’s team will continue to study the effect of gene editing on their five cloned monkeys.The group disabled a gene, BMAL1, that has a crucial role in maintaining circadian rhythm (生理节奏)，the internal clock that helps a healthy sleep-wake cycle.In people, BMAL1 mutations have been linked to diabetes, hypertension and depression.

　　The monkeys with the disabled BMAL1 genes move more at night and sleep less overall.They also display psychosis-related symptoms, such as fear and anxiety, when put in unfamiliar environments.

　　The team ’ s next step is to look in detail at the neural (神经的`)mechanisms that might create these problems.It will also take advantage of the genetically identical monkeys to hunt for diagnostic markers of circadian rhythm-related disorders and possible treatments.

　　1.Why were the genetically identical monkeys cloned?

　　A.To prove scientists’ innovation in cloning animals.

　　B.To study the rare characteristics of cloned monkeys.

　　C.To explore many possibilities for monkeys’ cognition.

　　D.To provide improved animal models of human diseases.

　　2.What does Mitchell Lazar think of cloning monkeys?

　　A.It is of little value.

　　B.It is of much practice.
