日期：2013-11-20 A Dartmouth-led team has found a more accurate method to determine the ages of boulders（岩石） deposited by tropical glaciers, findings that will likely influence previous research of how climate change has impacted ice masses around the equator（... 阅读全文>>

日期：2013-11-20 UT Dallas computer scientists have developed a technique to create 3-D images that finds practical applications of a theory created by a famous mathematician. This technique uses anisotropic（各向异性的） triangles -- triangles with sides that vary... 阅读全文>>

日期：2013-11-20 For nearly as long as astronomers have been able to observe asteroids（小行星） , a question has gone unanswered: Why do the surfaces of most asteroids appear redder than meteorites（陨石） -- the remnants of asteroids that have crashed to Earth? In... 阅读全文>>

日期：2013-11-19 Researchers now have stronger evidence of granite（花岗岩） on Mars and a new theory for how the granite -- an igneous rock（火成岩） common on Earth -- could have formed there, according to a new study. The findings suggest a much more geologically... 阅读全文>>

日期：2013-11-19 From a bacteria's perspective the environment is one big DNA waste yard. Researchers have now shown that bacteria can take up small as well as large pieces of old DNA from this scrapheap（废料堆） and include it in their own genome. This discovery m... 阅读全文>>
