  如果让你选择一个动物，你准备选哪个？前段时间，纽约著名恶婆Leona Helmsley给她的爱犬留下巨额遗产，却没给孙子留下一个子儿，我说这女人前世一定是狗养的，不，今生就是。 
  
  
  
  中国日报网环球在线9月5日消息 英国人工授精与胚胎学管理局（HFEA）9月5日宣布，人类与动物细胞混合起来制造胚胎并用于医学研究原则上可以开展。
  
  
  据英国媒体报道，HFEA女发言人5日说，该机构将根据每次的研究申请，逐个进行审查。
  
  
  去年11月6日，来自纽卡斯特大学和伦敦国王学院的两个研究小组向HFEA提出将人类与动物细胞混合起来制造胚胎并用于医学研究的申请。研究者计划从患有特殊病症的病人的皮肤细胞中提取细胞核，植入剔除了细胞核的牛或兔子的卵细胞中，制造出一个杂交胚胎细胞。
  
  
  反对者和一些宗教组织称，这项研究可能会颠覆人与动物之间的差别。还有一些伦理学专家称这项计划令人反感，听起来像最疯狂的天方夜谭。
  
  
  去年12月，英国政府发表白皮书，其中包含将几乎所有人和动物胚胎研究定为违法的提议，从而引发一些科学家和医学研究组织的反对。据悉，这项研究一直得到一些诺贝尔奖获得者以及一些科学、医学研究机构的支持。
  
  
  HFEA今年9月3日公布了对这项备受争议的计划的民意测验，结果显示多数人对科学家们制造人兽杂交胚胎的反应平和。

  将动物的卵子去除细胞核，然后将一个提取自成人细胞的细胞核注入其中，从而制造出一枚混合卵子。这样制造出的混合卵子主要还是人类细胞，因为它99.9％的成分是人，另外0.1％的成分是动物。

  The cause of death was heart failure, her longtime spokesman, Howard J. Rubenstein, said.
  
  Mrs. Helmsley came to public attention after her marriage in 1972 to New York’s pre-eminent real estate investor and broker, Harry B. Helmsley. In his heyday, the forceful, respected Mr. Helmsley had accumulated real-estate worth an estimated $5 billion, including the Empire State Building, the Helmsley Building on Park Avenue, and the Flatiron Building.
  
  Mr. Helmsley divorced his wife of 33 years to marry her, but Mrs. Helmsley’s real power began in 1980 with her appointment as president of the Helmsley hotels. The chain at the time ran 30 hotels around the country, including the Park Lane and St. Moritz in New York, as well as the Harley and the flagship Helmsley Palace.
  
  “It was Harry’s idea,” she said at the time. “He thinks I deserve it, he thinks I’m good. He said I was so involved in the business, I might as well be president and he’d be chairman. He said the best thing about it was that the board of directors meeting was over when we got out of bed.”
  
  Although hotel employees throughout the Helmsley empire were aware of Mrs. Helmsley’s hair-trigger temper and had arranged a warning system when she left her apartment on the way to one of the hotels, it was not until she starred in glossy advertisements for the hotels that she became a household name. The first ads, for the Harley, showed a smiling Mrs. Helmsley proclaiming that she wouldn’t settle for skimpy towels and couldn’t get along without a phone in the bath, and “why should you?” Occupancy increased to 70 percent from 25 percent.
  
  The Harley success led to ads for the Helmsley Palace. Mrs. Helmsley, in evening dresses revealing more than a little décolletage, posed in various settings in the hotel, proclaiming “It’s the only Palace in the world where the Queen stands guard.” Later, the hotel gift shop featured outsize gilt-trimmed playing cards, every second card featuring pictures of the Queen.
  
  The advertisements appeared for a decade, and they worked. Mrs. Helmsley and her insistence on first-rate service gave the Helmsley hotels a personality.
  
  George Lois, a well-known advertising executive, gave another reason in the anti-Helmsley book “Palace Coup” by Michael Moss. “The employees in the photos look at her as if they’re scared to death,” Mr. Lois said. “Her attitude fit right in with the mood of the Reagan administration: It’s O.K. to chew out the little guy.’’
  
  Some of the Queen’s luster was tarnished in 1986 when court documents and law enforcement officials said she had failed to pay sales taxes in New York on hundreds of thousands of dollars of jewelry she purchased at Van Cleef & Arpels, the exclusive Manhattan store. Two senior store officers were indicted on charges that they operated a scheme by which customers with out-of-state addresses could have their purchases recorded as being mailed to them, thus avoiding city and state taxes.
  
  According to the records, Mrs. Helmsley made 10 such jewelry purchases that were recorded as having been mailed to the Helmsley estate in Connecticut. Two of the specified purchases totaled $485,000, which would have required taxes of $40,000. Mrs. Helmsley’s lawyers said she had believed that the price she was paying was inclusive of sales tax. But in 1990 a State Supreme Court judge, John A.K. Bradley, revealed that Mrs. Helmsley had admitted before grand juries in 1985 that she had “actively participated from a fraudulent sales-tax scheme perpetrated on the state of New York.” The two Van Cleef officials later pleaded guilty in the case, but Mrs. Helmsley had received a grant of immunity and could not be charged.
  
  In 1987 a series of adverse articles in The New York Post about the Helmsleys, set off by one of their disgruntled employees, led to a broad investigation. The following year Harry and Leona Helmsley were indicted by federal and state authorities on charges that they had evaded more than $4 million in income taxes by fraudulently claiming as business expenses luxuries they purchased for Dunnellen Hall in Greenwich, Conn, a 28-room Jacobean mansion on 26 acres with a sweeping view of Long Island Sound that they bought in 1983. . The house was the setting for a 1968 movie, “A Lovely Way to Die,” starring Kirk Douglas.

  中国人在报道这一类新闻时总喜欢使用耸人听闻的字眼。所谓“人兽杂交”是指人和动物通过性交而产生新的一代，人和动物的基因各占一半。英国批准的这一项计划不过是使用基因技术在人类的基因中加注约不到千分之一的动物基因，来治疗某些疾病。这和“人兽杂交”有着天壤之别。
  
  要知道，许多哺乳类动物的基因有很多相同之处。人和牛的基因甚至有90%以上是相同的。但那并不代表我们人就是牛，也不能说牛就是人。即使我们人类之间基因还是有微小的差别的。我们人类的基因中注入千分之一的牛的基因后，我们还是人类。何况，这种基因的注入是有所针对和控制的，只改变某个很小的特征，并不是要创造出一个新的物种。
