Bush used the veto for the first time.

George Bush finally vetoed a bill this week after five and a half years in office. (1) Strangely, this is a plan that most Americans support: it will expand federal funding for embryonic stem cell research. Both the House of Representatives and the Senate passed the bill by a large margin, but it did not reach the level of veto, so Mr. Bush's words are final, at least before the mid-term elections in 1 1 month.

This week, George? Bush finally exercised his veto power for the first time in his five and a half years as president. Strange to say, this is a bill that most Americans support-increasing federal funding for embryonic stem cell research. Although both the Senate and the House of Representatives passed the bill, they did not get a majority to avoid the president's veto power. So Bush's opinion is decisive, at least until the mid-term elections in June 1 1.

Stem cells are cells that have not yet decided what they want to be when they grow up. In other words, they can become blood cells, brain cells or almost any other type of cells. Their versatility makes them very useful in medical research. The biggest obstacle is that the best stem cells are obtained from human embryos, which will kill the embryos. For the most ardent anti-abortion people, including Mr. Bush and many of his core supporters, this is murder. Proponents of embryonic stem cell research point out that groups of embryos are produced during fertility treatment, and most of them are frozen or destroyed indefinitely. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _. (Is it really wrong to apply them to research that may save lives? (2) Yes, Mr. Bush said on July 65438+ in 2009 that there were some families standing next to him who "adopted" others' frozen embryos and used them to give birth to their own children.

Stem cells are cells that have not yet been identified as mature cells. In other words, they can become blood cells, brain cells or almost all other types of cells. Their versatility makes them very useful in medical research. The ethical problem that hinders stem cell research is that the best stem cells are collected from killed human embryos. For most people who are firmly opposed to abortion, including Bush and his core supporters, this is murder. Proponents of stem cell research point out that the embryos used in the research are all formed by artificial conception, and most of them will be frozen or killed indefinitely. Is it really wrong to apply them to research that may save lives? In July 2009, 65438+ Bush said, yes. Some families who "adopted" other people's frozen embryos to conceive their own children also stood on his side.

Bush's veto did not stifle stem cell research. Scientists who refuse federal funds can do whatever they want. The government still funds research on stem cells extracted from adults, which will not kill D. Mr. Bush made a decision in 20001year to allow federally funded scientists to conduct experiments on the few embryonic stem cell "lines" that existed at that time and could be propagated in the laboratory.

Bush's veto did not completely stop stem cell research. Scientists who disdain federal funding will do it if they want to. The government will still provide funds for adult stem cell research, which does not have to kill stem cell donors. In 200 1 year, Bush decided to allow government-funded scientists to conduct experiments only on a few collected stem cell lines, which can be propagated in the laboratory.

Nevertheless, scientists are very angry with Mr. Bush. Federal funds will definitely push them to those treatments faster. Research based on adult stem cells may be promising, but it is far less promising than research based on embryonic stem cells. Some people worry that the gene pool represented by these dozens of embryonic stem cell lines is too narrow, and they cannot expand indefinitely without destroying them. (4) Other countries, such as Britain and China, are enthusiastically conducting embryonic stem cell experiments. But the most innovative country in the world is shrinking.

However, scientists are still very dissatisfied with Bush. The federal government's funding will certainly push them to find a cure for those intractable diseases faster. Although adult stem cell research may have a good prospect, it is still not as good as embryonic stem cells. Others worry that the gene spectrum contained in those frozen embryonic stem cell lines is too narrow, and its application scope will not expand if it is not destroyed. Other countries, such as Britain and China, are conducting embryonic stem cell experiments in full swing, while the United States, the most innovative country in the world, has backed out.
