Fusion conditions - Particle simulation studies of divertor plasmas
"Nuclear fusion" is the melting of light nuclei into heavier ones, a process that according to the laws of physics releases enormous amounts of energy. For the past 50 years many scientists have sought ways of harnessing this fusion reaction under controlled reactor conditions as a safe, clean and... view more (2002-02-25)

Laser Instead Of A Diamond Saw
St. Petersburg physicists have developed a plant that allows to cut sapphire crystals into almost ideally smooth plates being fractions of millimeter thick. The approach suggested by the researchers fundamentally differs from the traditional one. They suggest that sapphire should not be sawn by a... view more (2004-10-22)

Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth.   view more (2007-09-21)

Atoms under the mantle
At a depth of 2900 kilometres, the layer between the Earth's mantle and its core has always intrigued geophysicists because they are unable to explain the seismic data it generates.   view more (2007-03-07)

The Sun Flooded Europe
It will be easy to predict typhoon appearance if you know where it arises. One of the cyclone forming regions is the northern part of the Mediterranean along the French and Italian coast. Most of last summer cyclones came from there and flooded many European countries and Southern Russia, and even... view more (2002-10-25)

Mountain ranges rise dramatically faster than expected
Two new studies by a University of Rochester researcher show that mountain ranges rise to their height in as little as two million years-several times faster than geologists have always thought.   view more (2006-01-27)

Geologists study China earthquake for glimpse into future
The May 12 earthquake that rocked Sichuan Province in China was the first there in recorded history and unexpected in its magnitude. Now a team of geoscientists is looking at the potential for future earthquakes due to earthquake-induced changes in stress.   view more (2008-07-07)

Glacial pace of erosion was not so slow, new technique shows
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work.   view more (2005-12-12)

Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming.   view more (2006-10-26)

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)

Size-specific cracking shakes out at the nanoscale
Certain sizes of nanostructures may be more susceptible to failure by fracture than others.   view more (2008-08-04)

Asian rubies come always with marble and salt
Ruby is mineralogically the chromiferous variety of corundum gemstone, in other words an aluminium oxide in which some of the aluminium ions have been substituted by chromium. Chromium contributes, along with vanadium, another metal constituent of ruby, to the crystal's red colour. The most prized... view more (2004-01-30)

Durham scientist explores Sichuan fault
Durham University expert, Alex Densmore, is to explore the fault lines that caused the May 12th earthquake in China that killed 69,000 people.    view more (2008-08-14)

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)

New model describes avalanche behavior of superfluid helium
By utilizing ideas developed in disparate fields, from earthquake dynamics to random-field magnets, researchers at the University of Illinois have constructed a model that describes the avalanche-like, phase-slip cascades in the superflow of helium.   view more (2007-04-25)

'Ultrasound' of Earth's crust reveals inner workings of a tsunami factory
Research announced this week by a team of U.S. and Japanese geoscientists may help explain why part of the seafloor near the southwest coast of Japan is particularly good at generating devastating tsunamis, such as the 1944 Tonankai event, which killed at least 1,200 people. The findings will help... view more (2007-11-16)

Ancient glaciers still affect the shape of North America, say scientists
Long after the disappearance of the glaciers that once covered much of North America, the land they rested upon is still recovering from their weight - and the slow movement of this recovery includes horizontal motion never seen before.   view more (2005-12-15)

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)

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)

San Andreas earthquake observatory achieves milestone as drillers penetrate the active fault zone
The San Andreas Fault Observatory at Depth (SAFOD) reached a significant goal on Aug. 2 when scientists drilled into a seismically active section of the fault approximately two miles below the surface of the Earth.   view more (2005-08-04)

Fibroblasts
Where should stem cells be taken for transplantation in case of deep burns - from embryos or from the marrow? Russian transplantologists have determined that the skin restores quicker when the cell from mesenchyme of the marrow are used. Within a month, the rat's burn wound area would decrease by... view more (2003-11-06)

Ceramic material revs up microwaving
Quicker microwave meals that use less energy may soon be possible with new ceramic microwave dishes and, according to the material scientists responsible, this same material could help with organic waste remediation.   view more (2008-08-29)

Technology uses live cells to detect food-borne pathogens, toxins
Researchers have developed a new technology that can simultaneously screen thousands of samples of food or water for several dangerous food-borne pathogens in one to two hours.   view more (2008-03-03)

Videos extract mechanical properties of liquid-gel interfaces
Blood coursing through vessels, lubricated cartilage sliding against joints, ink jets splashing on paper-living and nonliving things abound with fluids meeting solids.   view more (2008-01-24)

Rerouting of Major Rivers in Asia Provides Clues to Mountains of the Past
Scientists have long recognized that the collision of the earth's great crustal plates generates mountain ranges and other features of the Earth's surface.   view more (2005-12-27)
