Second Undersea Canyon Expedition To Study Ocean Crust Construction![]() The second Duke University-led expedition since 1999 to a deep underwater canyon will take geologists to another place in the eastern Pacific Ocean where new sea floor was forged out of volcanic lava within the past several million years. Officials Deny Russian Spaceport A Threat ![]() Russia's space agency has established that space activities connected with the Baikonur cosmodrome do not impact directly on the health of nearby residents. Major Caribbean Earthquakes And Tsunamis A Real Risk ![]() A dozen major earthquakes of magnitude 7.0 or greater have occurred in the Caribbean near Puerto Rico, the U.S. Virgin Islands and the island of Hispaniola, shared by Haiti and the Dominican Republic, in the past 500 years, and several have generated tsunamis. NASA/French Satellite Data Reveal New Details Of Tsunami ![]() For the first time, orbiting satellites have observed and measured a major tsunami event in open ocean, the Indian Ocean tsunami that resulted from the magnitude 9 earthquake southwest of Sumatra on December 26. The measurements are of tremendous value to researchers worldwide and will aid our understanding of these events. More Than Monkey See, Monkey Do? ![]() Mammals other than humans can distinguish between different speech patterns. Neuroscientists in Barcelona report that rats, like humans (newborn and adult) and Tamarin monkeys, can extract regular patterns in language from speech (prosodic) cues. The report appears in the January issue of the Journal of Experimental Psychology: Animal Behavior Processes, which is published by the American Psychological Association. NASA Details Earthquake Affects On The Earth ![]() NASA scientists using data from the Indonesian earthquake calculated it affected Earth's rotation, decreased the length of day, slightly changed the planet's shape, and shifted the North Pole by centimeters. The earthquake that created the huge tsunami also changed the Earth's rotation. Queen's Discovery Sheds New Light On Ancient Temperatures ![]() A new discovery by a team of Queen's University scientists suggests that ancient earth was much colder than previously thought � a discovery that has broad implications for those studying the earth's climate. |
Our Cosmic Self-Esteem![]() Interview with Sir Martin Rees, Part 3- Britain's Astronomer Royal, Martin Rees, took time from his busy schedule to talk with Astrobiology Magazine's Chief Editor and Executive Producer, Helen Matsos.

Earth Is Still Ringing From Quake ![]() Almost two weeks after the earthquake and ensuing tsunami that devastated huge areas of Asia, the Earth is still ringing like a bell, according to ANU scientists. Subduction Zone, Shallow Depth Make Lethal Mix In Earthquake ![]() The position of the earth's tectonic plates is key, says Lehigh University seismologist. The location of the recent earthquake that triggered a deadly tsunami in the Indian Ocean came as no surprise to geologists, says Anne Meltzer, a world-renowned seismologist at Lehigh University. Ants Genetic Engineering Leads To Species Interdependency ![]() Findings reported last week reveal how an evolutionary innovation involving the sharing of genes between two ant species has given rise to a deep-seated dependency between them for the survival of both species populations. The Dynamo In The Cornfield ![]() In an underground bunker that brushes up against a barnyard on one side and a cornfield on the other, scientists from the University of Wisconsin, Madison, are trying to solve an enduring cosmic mystery: how does the Earth generate its magnetic field - the vast, invisible web that shapes the aurora, makes compass needles point north, and shields us from solar storms? |
