Monitoring Yellowstone earthquake swarms
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)
Climate variability impacts the deep sea
Deep-sea ecosystems occupying 60% of the Earth's surface could be vulnerable to the effects of global warming warn scientists writing in the Proceedings of the National Academy of Sciences. view more (2009-11-03)
Nanoparticle synthesis allows particle size and shape to be tailored to end applications
Nanomaterials are increasingly gaining the attention of not only the scientific community, but also the public due to their unique properties which endear them to new and exciting applications. view more (2005-11-30)
Lunar rocks suggest meteorite shower
New age measurements of lunar rocks returned by the Apollo space missions have revealed that a surprising number of the rocks show signs of melting about 3.9 billion years ago, suggesting that the moon - and its nearby neighbor Earth - were bombarded by a series of large meteorites at that time. view more (2006-04-13)
Scientists penetrate fossil magma chamber beneath intact ocean crust - achieving scientific 'first'
Approximately 800 km west of Costa Rica an international team of scientists aboard the research drilling ship JOIDES Resolution has¡-for the first time-recovered black rocks known as gabbros from intact ocean crust. view more (2006-04-21)
New study explains why hotter is better for insects
Organisms have been able to adapt to environments ranging from cold polar oceans to hot thermal vents. However, University of Washington researchers have discovered a limit to the powerful forces of natural selection, at least when it comes to the adaptation of insects to cold temperatures. view more (2006-10-03)
Looking for life on Jupiter's icy moon Europa
While NASA and the European Space Agency focus on Mars rovers and future missions to search for life on the Red Planet, a determined core of scientists is lobbying for equal attention to a place they feel is just as likely to harbor life-Jupiter's icy moon Europa. view more (2007-02-26)
Watching rocks grow: Theory explains landscape of geothermal springs
Scientists at the University of Illinois at Urbana-Champaign have successfully modeled the spectacular landscapes seen at geothermal hot springs. view more (2006-07-06)
Nature press release for 12 July issue
[412175] RELICS: NEW HOMINID FOSSILS (pp175-178, 178-181; N&V) Some glimpses of the earliest human ancestry are revealed this week as researchers present new fossils of hominids — members of the human family — that lived more than 5 million years ago in what is now Ethiopia. Yohannes... view more... (2001-07-12)
Methane doesn't necessarily mean life on Mars, says Dartmouth study
Two Dartmouth researchers have weighed in on the debate over whether the presence of methane gas on Mars indicates life on the red planet. Mukul Sharma, Assistant Professor of Earth Sciences, and Chris Oze, a postdoctoral fellow, argue that the Martian methane could have been produced by inorganic processes just as easily as by bacteria. view more (2005-06-08)
Scientists visualize assembly line gears in ribosomes, cell's protein factory
Even as research on the ribosome, one of the cell's most basic machines, is recognized with a Nobel Prize, scientists continue to achieve new insights on the way ribosomes work. view more (2009-10-16)
Automating heating and ventilation
Homeowners looking to save heating costs can find themselves in a quandary. If they apply too much insulation to the outside walls and install airtight windows, the inflow of fresh air from outside is reduced. To prevent stale and humid air from causing mold to grow, approximately half of the air volume should be renewed every hour. But... view more... (2003-01-23)
Earth's original ancestor was LUCA, not Adam nor Eve
Here's another argument against intelligent design. An evolutionary geneticist from the Université de Montréal, together with researchers from the French cities of Lyon and Montpellier, have published a ground-breaking study that characterizes the common ancestor of all life on earth, LUCA (Last Universal Common Ancestor). view more (2008-12-18)
Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. view more (2007-05-11)
Marine bacterium suspected to play role in global carbon and nitrogen cycles
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. view more (2005-09-23)
Uranium isotope ratios are not invariant, researchers show
For years, the ratio of uranium's two long-lived isotopes, U-235 and U-238, has been considered invariant, despite measurements made in the mid-1970s that hinted otherwise. view more (2007-10-24)
NASA's Cassini images reveal spectacular evidence of an active moon
Jets of fine, icy particles streaming from Saturn's moon Enceladus were captured in recent images from NASA's Cassini spacecraft. The images provide unambiguous visual evidence the moon is geologically active. view more (2005-12-07)
Geologist troubleshoots silica problem at geothermal plants
In the debate over alternative energy resources, geothermal technology has received scant media attention. Advocates call it one of the cleanest, sustainable energy resources available. However, steep construction, equipment and drilling costs have prevented more widespread development of geothermal technology. view more (2007-03-14)
Deep biosphere research points to new methods for recovering petroleum
Miles below us, deep within Earth's crust, life is astir. Organisms there are not the large creatures typically envisioned when thinking of life. view more (2008-10-08)
All the carbon counts
Cutting down forests for agriculture vents excess carbon dioxide into the air just as industrial activities and the burning of fossil fuels do. view more (2009-05-29)
