U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows. view more (2009-02-09)
Iron on its route to the sea-floor: A new path
Iron dust, the rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or--a surprising new study finds--float up from the sea floor in the material spewed from hydrothermal vents. view more (2009-02-09)
Evidence of ancient hot springs on Mars detailed in Astrobiology journal
Data from the Mars Reconnaissance Orbiter (MRO) suggest the discovery of ancient springs in the Vernal Crater, sites where life forms may have evolved on Mars, according to a report in Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. view more (2009-02-12)
Novel protein complex enables survival in hostile environment
Biswarup Mukhopadhyay and Eric Johnson from the Virginia Bioinformatics Institute at Virginia Tech have discovered a novel enzyme that represents an ancient detoxification system and provides a clue to the development of early metabolism on earth. view more (2005-11-17)
Meteor impacts: Life's jump starter?
Meteor impacts are generally regarded as monstrous killers and one of the causes of mass extinctions throughout the history of life. view more (2005-08-09)
Bacteria 'Feed' on Earth's Ocean-Bottom Crust
Seafloor bacteria on ocean-bottom rocks are more abundant and diverse than previously thought, appearing to "feed" on the planet's oceanic crust, according to results of a study reported in this week's issue of the journal Nature. view more (2008-05-29)
Volcanic plumbing dictates development of deep-sea hydrothermal vents
After years of results that repeatedly dogged him, University of Oregon geologist Douglas R. Toomey decided to follow the trail of data surfacing from the Pacific Ocean. In doing so, he and his collaborators may have altered long-held assumptions involving plate tectonics on the ocean floor. view more (2007-03-22)
Radioactive crystals help identify and date ore deposits
Reddish-brown crystals of a radioactive mineral called monazite can act as microscopic clocks that allow geologists to date rock formations that have been altered by the action of high-temperature fluids, a process that frequently leads to the formation of rich ore deposits. view more (2006-08-01)
Study outlines eruption at undersea volcano
An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean's surface near the Mariana Islands northwest of Guam. view more (2006-05-25)
Scientists gain new insights into 'frozen' methane beneath ocean floor
An international team of scientists supported by the Integrated Ocean Drilling Program (IODP) has completed a unique research expedition aimed at recovering samples of gas hydrate, an ice-like substance hidden beneath the seafloor off Canada's western coast. view more (2005-11-01)
Genomics of large marine animals showcased in the Biological Bulletin
Though the slow moving purple sea urchin may look oblivious, lacking a head, eyes and ears, this prickly creature has an impressive suite of sensory receptors to detect outside signals. view more (2008-06-25)
Foot-dragging Mars rover finds Yellowstone-like hot spring deposits
Deposits of nearly pure silica discovered by the Mars Exploration Rover Spirit in Gusev Crater formed when volcanic steam or hot water (or maybe both) percolated through the ground. view more (2008-05-23)
Ancient organisms discovered in Canadian gold mine
Scientists have suspected that the three known domains of life -- eukaryotes, bacteria, and archaea -- branched off and went their separate ways around three billion years ago. But pinning down the time of that split has been an elusive task. view more (2007-08-21)
Deep-sea rocks point to early oxygen on Earth
Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists. view more (2009-03-25)
Discovering an ecosystem beneath a collapsed Antarctic ice shelf
The chance discovery of a vast ecosystem beneath the collapsed Larsen Ice Shelf will allow scientists to explore the uncharted life below Antarctica's floating ice shelves and further probe the origins of life in extreme environments. view more (2005-07-19)
Volcanic Activity Shaped Mercury After All
Scientists have long anguished over how little is known about Mercury, the innermost of the four terrestrial planetary bodies in our solar system. view more (2008-07-07)

The Seismological Society of America (SSA) is an international scientific society devoted to the advancement of seismology and its applications in understanding and mitigating earthquake hazards and in imaging the structure of the earth. view more (2009-04-10)
CU-Boulder technology used to identify unexpected bacteria in cystic fibrosis patients
Molecular technology developed by a University of Colorado at Boulder professor to probe extreme life forms in undersea hydrothermal vents has been used to identify unexpected bacteria strains in the lung fluid of Denver children suffering from cystic fibrosis, findings that may lead to more effective therapies. view more (2007-12-04)
Nanoparticle synthesis allows particle size and shape to be tailored to end applications
