Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair.   view more (2008-01-04)

Remnants of ice age linger in gravity
Researchers have uncovered a large area of low but increasing gravity over North America - the lingering effect of the last ice age when sheets of ice sometimes three kilometres thick covered nearly all of Canada and the northeastern U.S.   view more (2007-05-11)

Hot climate could shut down plate tectonics
A new study of possible links between climate and geophysics on Earth and similar planets finds that prolonged heating of the atmosphere can shut down plate tectonics and cause a planet's crust to become locked in place.   view more (2008-05-13)

'Finger rafting:' Ice sheets that mesh when they meet
A study reported in Physical Review Letters demonstrates how ice sheets sometimes interlace when they meet, rather than riding over or under each other, and discusses the implications for other phenomena from plate tectonics of the Earth's surface to the design of self-assembling nanostructures.   view more (2007-03-02)

Earth's Moving Crust May Occasionally Stop
The motion, formation, and recycling of Earth's crust-commonly known as plate tectonics-have long been thought to be continuous processes. But new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth's geologic history, and may do so again. The findings... view more (2008-01-10)

UCL scientists create first earthquakes in the laboratory
Scientists at UCL have recreated earthquakes in the laboratory for the first time allowing them to better understand the origin of the largest and most violent earthquakes. This is the first time scientists have been able to generate and observe deep and intermediate focus earthquakes in the... view more (2002-11-14)

Scripps/UCSD geophysicist among international team finding evidence of first plate tectonics
Identification of the oldest preserved pieces of Earth's crust in southern Greenland has provided evidence of active plate tectonics as early as 3.8 billion years ago, according to a report by an international team of geoscientists in the March 23 edition of Science magazine.   view more (2007-03-23)

Biologist and geologist honoured in major international prizes
A Swiss developmental biologist, Walter Gehring, and a French geologist, Xavier Le Pichon, have each been awarded a prize of 1,000,000 Swiss Francs for their work on genes that control the development of the eye, and plate tectonics respectively. [Note: Swiss Francs 1 million is equivalent to... view more (2002-09-10)

Hotspots or Not? Isotopes Score One for Traditional Theory
One great beauty of plate tectonics theory is that it explains so many geological phenomena at one time. But plate tectonics could not explain the location of many volcanic islands - Hawaii, the Azores or the Galapagos Islands, often called "hotspots" - far from the edge of tectonic... view more (2006-12-07)

International Conference on Earth Science Research
These include the fields of sedimentology - the study of sediments; biogeography - pattern and distribution of living organisms; geomorphology - land forms and processes, and tectonics - the structure and movement of the Earth's crust.   view more (1999-08-16)

Eastern California shear zone puzzles seismologists
Residents and seismologists in Northern California focus on the San Andreas Fault, but a Penn State researcher thinks more questions should be asked about the Eastern California Shear Zone, a fault that ends or dissipates without a clear connection.   view more (2005-10-18)

Tectonic plates act like variable thermostat
Like a quilt that loses heat between squares, the earth's system of tectonic plates lets warmth out at every stitch.   view more (2007-08-14)

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)

Is a Russian peninsula really part of North America?
For many years geologists have harbored a belief that the Kamchatka Peninsula, shrouded in mystery and secrecy on Russia's east coast, actually sits on the same tectonic plate as the mainland United States, Canada and Mexico.   view more (2006-05-03)

Sumatra megaquake defied theory
The risks of Sumatra-style mega-quakes around the world have been sorely misjudged, say earth scientists who are re-examining some of the pre-December 2004 assumptions scientists made about such rare events.   view more (2006-03-28)

Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times... view more (1999-06-08)

Mars Express reveals the Red Planet's volcanic past
A new analysis of impact cratering data from Mars reveals that the planet has undergone a series of global volcanic upheavals. These violent episodes spewed lava and water onto the surface, sculpting the landscape that ESA's Mars Express looks down on today.   view more (2008-03-17)

Folded sediment unusual in Sumatran tsunami area
Sediment folding may have added to the exceptionally large tsunami that struck Sumatra on Dec. 26, 2004, according to an international team of geologists. "Tsunami models consider the rebound of the plate during the earthquake, but do not include permanent deformation, like folding, of the... view more (2007-02-05)

10 questions shaping 21st-century earth science identified
Ten questions driving the geological and planetary sciences were identified today in a new report by the National Research Council. Aimed at reflecting the major scientific issues facing earth science at the start of the 21st century, the questions represent where the field stands, how it arrived... view more (2008-03-13)

New data shakes accepted models of collisions of the Earth's crust
New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape.   view more (2007-02-08)

Lighting the Way: Measuring Surface Tension Just Got Easier
Inventors at Oxford University have developed a new method to indirectly measure the surface tension of liquid by tracking reflected light intensity to assess the surface configuration. The procedure is reliable, repeatable, quick to set-up and use, contact-less and non-destructive. Surface tension... view more (2003-09-05)

Building for the Future
Providing motorists with real time information on incidents and road delays, the Highway's Agency state-of-the-art National Traffic Control Centre (NTCC) is taking shape. From 2004, NTCC will play a vital role in the way traffic is managed. Based in the West Midlands, the purpose built centre has... view more (2003-12-01)

Lifeburn - heating systems for domestic application
Heating systems must adjust the thermal power to the needs of the user through the modulation of their thermal power. So a major efficiency, less polluting emissions and more comfort can be obtained. However, the difficulty to develop new radiant burners has slow down the appearing of new... view more (2002-09-23)

Stress Buildup Precedes Large Sumatra Quakes
The island of Sumatra, Indonesia, has shaken many times with powerful earthquakes since the one that wrought the infamous 2004 Indian Ocean tsunami. Now, scientists from the California Institute of Technology and the Indonesian Institute of Sciences are harnessing information from these and earlier... view more (2008-05-28)

UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the... view more (2007-06-01)
