　　Stacey Gabriel of the Broad Institute says mapping just one SNP used to cost almost a dollar per patient (患者). Today, she says, it often costs less than one cent. In the past, it was possible to test only one hundred genotypes (基因型) in a day. But now, she says, it is possible to perform millions of tests in a day.

　　In the past, some scientists have questioned whether using haplotypes is the best way to find genetic information. Some still express concerns about the effectiveness (效力) of this method. But several studies already have been published using the new information.

　　For example, scientists at Yale University in New Haven, Connecticut (康涅狄格), used the HapMap to connect a gene to macular degeneration (恶化). That is a leading cause of blindness in older people.

　　VOICE TWO:

　　Palestinians in a prison in Israel have found the ruins of an ancient Christian place of worship. Some archaeologists (考古学家) say it could be the oldest church ever found in the homeland of Jesus. But other experts say it is unlikely the church is as old as suggested.

　　The prison is in Megiddo. Israeli officials had ordered a dig to search for ancient objects before a planned addition to the prison (监狱). The government often orders such digs before building in historically important areas. Megiddo is where the battle of Armageddon (哈米吉多顿(世界末日善恶决战的战场)) takes place in the Bible.

　　VOICE ONE:

　　The Israeli Antiquities Authority began the dig months ago with about sixty prisoners for labor. On October thirtieth, one of them discovered the floor of the ancient building. Archeologist Yotam Tepper, the leader of the dig, called it "the find of a lifetime."
