Geotimes December 2003 Hatheway et al.	Applied Geology in Service of the Public Welfare Engineering geologists play a crucial role in providing geological information to the public.
Geotimes December 2003 Sara Pratt	Ultraslow spreading centers In two of the deepest and most remote parts of the world, scientists have discovered a new class of "ultraslow" spreading ridge, where cold, solid slabs of mantle are being heaved to the surface to build new seafloor.
Technology Research News December 3, 2003 Kimberly Patch	Software paraphrases sentences Humans have many ways of expressing a given idea, but paraphrasing is a serious challenge for literal-minded computers. A new system that learns by tracking news stories from several sources is able to paraphrase at the sentence level.

Geotimes December 2003 Sara Pratt	Cool Cambrian triggers life A controversial hypothesis put forth by a team of German researchers says the Cambrian explosion -- the momentous increase in biodiversity 542 million years ago that spawned most modern animal groups -- was caused by life itself.
Geotimes December 2003 Naomi Lubick	Glacial earthquakes Seismologists have fingered glaciers as one source of newly discovered "slow" earthquakes.
Geotimes December 2003 Naomi Lubick	Vertebrates and tectonics Paleontologists suggested some new twists on tectonics and ecosystems at the annual meeting of the Society of Vertebrate Paleontology (SVP), held mid-October. Their ideas might offer answers to some key conundrums regarding extinction, speciation and the global distribution of vertebrate species.
Geotimes December 2003 Megan Sever	La Nina controls Amazon floodplain A team of geologists linked the floodplain depositional layers to rapidly rising floods that occur during La Nina events in Bolivia. Rather than corresponding to annual flooding events in the rainforests, each large sediment influx corresponded to a La Nina event in the historic record.
Geotimes December 2003 Naomi Lubick	Unknown Future for Coral Reefs Coral reefs are in danger and their recovery, when compared to historic coral reefs, is not assured. Though action is necessary to preserve reefs today, researchers do not know enough about how reefs function to guarantee that conservation and remediation will work.
Geotimes December 2003 David Applegate	Water is for Fightin' The High Plains aquifer could be a casualty in a political battle to prevent coordinated scientific characterization of this important groundwater system.
