The Radar Search For Martian Water
Until the last few years, Mars has been regarded as a cold, arid world that lost most of its water long ago. However, recent observations by NASA's Mars Global Surveyor and Mars Odyssey spacecraft have provided tantalising evidence that huge amounts of water may be hidden just below the surface.... view more (2003-04-01)

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)

Study identifies food-related clock in the brain
In investigating the intricacies of the body's biological rhythms, scientists at Beth Israel Deaconess Medical Center (BIDMC) have discovered the existence of a "food-related clock" which can supersede the "light-based" master clock that serves as the body's primary timekeeper.   view more (2008-05-23)

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments
UC Irvine School of Medicine researchers have discovered how new neurons born from endogenous neural stem cells are sent to regions of the brain where they can replace old and dying cells, a finding that suggests how stem cell therapies can be specifically targeted to brain regions affected by... view more (2005-06-24)

Immigrant Sun: Our star could be far from where it started in Milky Way
A long-standing scientific belief holds that stars tend to hang out in the same general part of a galaxy where they originally formed. Some astrophysicists have recently questioned whether that is true, and now new simulations show that, at least in galaxies similar to our own Milky Way, stars such... view more (2008-09-16)

Deployment to Iraq war associated with increased risk for adverse neuropsychological effects
U.S. Army soldiers who return from military deployment to the Iraq war have an increased risk for mild neuropsychological compromise, including poorer memory and sustained attention performance and greater feelings of tension and confusion.   view more (2006-08-02)

Climate variation in the tropical Pacific: coral provides proof
The Younger Dryas period, about 12 000 years ago, was marked by a sharp cooling event in the Northern Hemisphere. Temperatures there fell by between 2 and 10°C. The East Antarctic in contrast experienced an episode of warming. Data have up to now been insufficient or too inconclusive to enable... view more (2004-05-03)

Stalagmites May Predict Next Big One along the New Madrid Seismic Zone
Small white stalagmites lining caves in the Midwest may help scientists chronicle the history of the New Madrid Seismic Zone (NMSZ) - and even predict when the next big earthquake may strike.   view more (2008-09-26)

San Andreas Fault Observatory at Depth reveals new insights into the 'earthquake machine'
The San Andreas Fault Observatory at Depth (SAFOD)-the first underground observatory to provide physical samples and real-time seismological data from deep inside an active fault zone-is yielding surprising new clues about the origin of earthquakes.   view more (2005-12-06)

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)

Undersea microbes active but living on the slow side
Deeply buried ocean sediments may house populations of tiny organisms that have extremely low maintenance energy needs and population turnover rates of anywhere from 200 to 2,000 years.   view more (2006-02-21)

Smithsonian coral biodiversity survey of Panama's Pearl Islands
A comprehensive survey of coral biodiversity in Panama's Las Perlas Archipelago, published in the journal Environmental Conservation by researchers from the Smithsonian Tropical Research Institute and their colleagues, has resulted in clear conservation recommendations for a new coastal management... view more (2008-07-08)

A new magnetic phenomenon may improve RAM memories and the storage capacity of hard drives
The application of 'displaced vortex states'-small magnetic circular movements of just a few thousandths of a millimetre-may accelerate the arrival of a new type of magnetic memory (MRAM) that does not disappear when a computer is switched off.   view more (2006-03-03)

For sardine and anchovy, El Ni'ħo events do not always have the same effects
Near the coasts of Peru and Chile, the Humboldt Current ecosystem is the world's most productive fishing zone. This cold-current zone, with frequent coastal upwellings (2), occupies less than 1 % of the world's ocean surface and provides 15 to 20 % of global maritime catches.   view more (2005-03-01)

Nanopowder Consisting Of Identical Particles
High-quality nanopowders made of refractory ceramics are a rare and very expensive material. All known methods of their manufacturing face the same problems - scanty quantities, extensive variety of particle sizes and expensive production. Researchers from the town of Tomsk have invented and... view more (2004-03-26)

'Missing Beach' Returns to Donegal
The sandy beach at Five-Finger Strand in Donegal has returned as predicted by University of Ulster researchers. The beach, which had lost its sand and for the past several years was an unattractive gravely surface, has now reverted to its former glory. A study, undertaken by the University's... view more (2004-02-19)

'Dead Zone' causing wave of death off Oregon coast
The most severe low-oxygen ocean conditions ever observed on the West Coast of the United States have turned parts of the seafloor off Oregon into a carpet of dead Dungeness crabs and rotting sea worms, a new survey shows. Virtually all of the fish appear to have fled the area.   view more (2006-08-11)

Geron Demonstrates hESC-derived cardiomyocytes improve heart function after myocardial infarction
Geron Corporation (Nasdaq: GERN) today reported its scientists and collaborators have demonstrated that human embryonic stem cell (hESC)-derived cardiomyocytes improve heart function when transplanted after myocardial infarction.   view more (2007-08-27)

Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.   view more (2006-02-17)

Getting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a... view more (2008-08-20)

Epileptic seizures can be triggered by rubbing the skin
An epileptic seizure can be triggered by repeatedly rubbing a small, well defined area of skin, reports research in the Journal of Neurology, Neurosurgery and Psychiatry. The phenomenon, described by the researchers as “rub epilepsy,” is described in a series of case studies. None of... view more (2001-03-13)

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)

Heat-seeking the invisible killers
Land-mines kill or maim some 20,000 people every year. Locating these loathsome weapons is vital. But what mine-busters really want is guidance - like that provided by a unique European infrared-camera system - on where to start searching.   view more (2005-02-11)
