Penn researchers engineer first system of human nerve-cell tissue
Researchers at the University of Pennsylvania School of Medicine have demonstrated that living human nerve cells can be engineered into a network that could one day be used for transplants to repair damaged to the nervous system. They report their findings in the February issue of the Journal of... view more (2008-02-27)

Supercomputer Unleashes Virtual 9.0 Megaquake in Pacific Northwest
On January 26, 1700, at about 9 p.m. local time, the Juan de Fuca plate beneath the ocean in the Pacific Northwest suddenly moved, slipping some 60 feet eastward beneath the North American plate in a monster quake of approximately magnitude 9, setting in motion large tsunamis that struck the coast... view more (2008-02-27)

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)

Frigid Enceladus: An unlikely harbor for life
A new model of Saturn's icy moon Enceladus may quell hopes of finding life there. Developed by researchers at the University of Illinois, the model explains the most salient observations on Enceladus without requiring the presence of liquid water.   view more (2007-08-15)

'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)

3-D computer models aid research of Earth's core
The work of a University of Alaska Fairbanks post-doctoral fellow will be included in an article appearing in the upcoming issue of the journal, Science.   view more (2006-11-29)

Teachers discover that bacteria prefer milk chocolate
Bacteria prefer milk chocolate to dark chocolate and will swim towards it on an agar plate, so teachers have found out this week (15-19 July) at a summer school run by the Society for General Microbiology at the University of Reading. The experiment is one of a series of A-level practicals... view more (2002-07-17)

CT better than plain radiographs in diagnosing lumbar spine fractures
Lumbar spine fractures in a majority of patients with trauma can be detected by routine trauma abdomen and pelvis CT compared to plain radiographs, according to a recent study conducted by radiologists at the University of Cincinnati in Cincinnati, OH.   view more (2007-05-07)

Unique imaging uncovers the invisible world where surfaces meet
Hoping to find new ways of addressing environmental pollution, a physicist at the University of Wisconsin-Milwaukee (UWM) has developed some novel ways to observe what happens inside a cell when it comes in contact with contaminants or when toxic substances touch soil and water.   view more (2006-10-30)

Crystals For Extreme Electronics
Like silicon, silicon carbide is semiconductor and in some aspects, its characteristics are even better. Electrical strength of silicon carbide is ten times higher than that of silicon, heat conductivity is three times higher. Crystals of silicon carbide are almost perfect for power electronics.... view more (2002-01-24)

A sea change for earthquakes
A reconstruction of land movements and changes in sea levels for three massive historic earthquakes in Alaska gives clues that may help scientists forecast future earthquakes and earthquake-triggered tsunami. To be published in this week's Journal of Quaternary Scienceč the findings should help... view more (2005-02-21)

What we can learn from the biggest extinction in the history of Earth
Approximately 250 million years ago, vast numbers of species disappeared from Earth. This mass-extinction event may hold clues to current global carbon cycle changes, according to Jonathan Payne, assistant professor of geological and environmental sciences.   view more (2007-08-10)

Mars rovers find new evidence of 'habitable niche'; perilous third winter approaches
Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter -- and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January... view more (2007-12-26)

Geologist urges seismic shift in process for selecting EarthScope study sites
EarthScope, an enormous, nationwide earth science project, is poised to revolutionize understanding of earthquakes, fault systems, volcanoes and the North American continent's structure.   view more (2005-10-17)

Seismologists see Earth's interior as interplay between temperature, pressure and chemistry
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse.   view more (2007-10-26)

Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought.   view more (2008-04-11)

ANALYTICA 2004: Trapping Smallest Bioparticles
The Institut für Mikrotechnik Mainz GmbH (IMM) and the Norwegian NorChip AS have jointly developed a chip-based ”-concentrator. Suited for application in biomedical diagnostics, the dielectrophoresis (DEP) chip permits selective separation and concentration of polarisable bioparticles such as... view more (2004-05-10)

Geologists recover rocks yielding unprecedented insights into San Andreas Fault
For the first time, geologists have extracted intact rock samples from 2 miles beneath the surface of the San Andreas Fault, the infamous rupture that runs 800 miles along the length of California.   view more (2007-10-05)

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)

Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean.   view more (2007-04-13)

Mercury's shifting, rolling past
Patterns of scalloped-edged cliffs or lobate scarps on Mercury's surface are thrust faults that are consistent with the planet shrinking and cooling with time. However, compression occurred in the planet's early history and Mariner 10 images revealed decades ago that lobate scarps are among the... view more (2008-03-18)

ADE-ADE-BIOTEC present their first on-site plant for the treatment of pig purines
The novelty of the system lies in the possibility of having an on-site installation at the farm itself, thus avoiding the transport of the purines to other, off-site plants for their treatment.   view more (2004-12-09)
