The Rise of Oxygen Caused Earth's Earliest Ice Age
Geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. view more (2009-05-07)
Food-crop yields in future greenhouse-gas conditions lower than expected
Open-air field trials involving five major food crops grown under carbon-dioxide levels projected for the future are harvesting dramatically less bounty than those raised in earlier greenhouse and other enclosed test conditions — and scientists warn that global food supplies could be at risk without changes in production strategies. view more (2006-06-30)
Med school discovery could lead to better cancer diagnosis, drugs
A Florida State University College of Medicine research team led by Yanchang Wang has discovered an important new layer of regulation in the cell division cycle, which could lead to a greater understanding of the way cancer begins. view more (2008-11-24)
Promethei Terra, southern highlands of Mars
These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show a part of the southern highlands of Mars, called Promethei Terra. The images were taken during orbit 368 in May 2004 with a ground resolution of approximately 14 metres per pixel. The displayed region is centred around longitude 118°... view more... (2004-10-12)
Ethanol vehicles pose a significant risk to human health, study finds
Ethanol is widely touted as an eco-friendly, clean-burning fuel. But if every vehicle in the United States ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations would likely increase. view more (2007-04-18)
ALIS a multi-eyed voyeur in a plasma universe
The Northern Lights are a visible result of physical processes in inner space. By studying the optical signal from the Northern Lights and similar phenomena, we can gain new knowledge about the physics behind them. In the long run such pure research may be of great importance for applications in our future supply of energy and for future space... view more... (2003-06-24)
INTELLIGENT ANTI-CORROSION COATING GIVES TURBINES IMPROVED PROTECTION
British materials scientists have invented a revolutionary new protective coating for high performance industrial and marine gas turbines. The new system called Smartcoat, can adapt to different types of corrosion modifying its chemical structure in response. The new coating can protect turbines in a wide range of different corrosion scenarios,... view more... (1999-09-09)
Short RNA strand helps exposed skin cells protect body from bacteria, dehydration and even cancer
Every minute, 30,000 of our outermost skin cells die so that we can live. When they do, new cells migrate from the inner layer of the skin to the surface of it, where they form a tough protective barrier. view more (2008-03-03)
The nanoworld of corrosion
The effect of corrosion has an impact on about 3% of the world's Gross Domestic Product. From a positive point of view, however, chemical attack of metal surfaces may result into surface nano-structures with very interesting technological applications such as catalysts and sensors. view more (2006-02-10)
Termite insecticide a potent greenhouse gas
An insecticide used to fumigate termite-infested buildings is a strong greenhouse gas that lives in the atmosphere nearly 10 times longer than previously thought, UC Irvine research has found. view more (2009-01-22)
Nanomicroscopy reveals the collective transport of gold atoms in real-time
Researchers at Delft University of Technology used a High Resolution Electron Microscope to observe in real-time the collective transportation of gold atoms in a thin layer. view more (2007-02-06)
Sunscreens from the sea
Tiny floating plants protect themselves against the damaging effects of the sun's ultra violet rays using compounds that may prove very useful to the skincare industry. Scientists at the Plymouth Marine Laboratory are now working with Boots Company plc to develop the potential of these natural sunscreens for human skincare. "Because... view more... (2001-07-18)
Layered approach may yield stronger, more successful bone implants
Researchers from the American Dental Association Foundation (ADAF) and the National Institute of Standards and Technology (NIST) have developed a new method for layering two kinds of biomaterials into one strong, yet porous unit that may lead to improved reconstruction or repair of bones. view more (2007-08-20)
Rich nations' environmental footprints tread heavily on poor countries
The environmental damage caused by rich nations disproportionately impacts poor nations and costs them more than their combined foreign debt, according to a first-ever global accounting of the dollar costs of countries' ecological footprints. view more (2008-01-22)
Scientists use meteors to investigate climate change and giant waves at the 'edge of space'
A new research radar based in Antarctica is giving scientists the chance to study the highest layer of the earth's atmosphere at the very edge of space. view more (2005-05-23)
New policies needed to combat Global Change, says Commissioner Wallström
Never before have policy makers faced a more challenging task than responding to global change, said EU Environment Commissioner Margot Wallström, in an article in the International Herald Tribune today (http://www.iht.com/articles/125563.html) and in a statement made for the launch of a new book on global change*... view more...

MU Engineers Develop Safer, Blast-Resistant Glass
To protect from potential terrorist attacks, federal buildings and other critical infrastructures are made with special windows that contain blast-resistant glass. However, the glass is thick and expensive. view more (2009-09-11)
New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. view more (2008-05-15)
Soil emissions are much-bigger-than-expected component of air pollution
Nitrogen oxides produced by huge fires and fossil fuel combustion are a major component of air pollution. They are the primary ingredients in ground-level ozone, a pollutant harmful to human health and vegetation. view more (2005-06-07)
Record air pollution above the Arctic
Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ã-lesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found. view more (2006-05-11)
