Pacific coast turning more acidic
An international team of scientists surveying the waters of the continental shelf off the West Coast of North America has discovered for the first time high levels of acidified ocean water within 20 miles of the shoreline, raising concern for marine ecosystems from Canada to Mexico.   view more (2008-05-23)

Global atmospheric carbon level may depend primarily on Southern Ocean
Circulation in the waters near the Antarctic coast may be one of the planet's critical means of regulating levels of carbon dioxide in the Earth's atmosphere, according to Princeton researchers.   view more (2006-06-23)

Power plants are major influence in regional mercury emissions
The amount of mercury emitted into the atmosphere in the Northeast fluctuates annually depending on activity in the electric power industry, according to researchers at the Yale School of Forestry & Environmental Studies.   view more (2006-07-24)

A bumpy shift from ice house to greenhouse
The transition from an ice age to an ice-free planet 300 million years ago was highly unstable, marked by dips and rises in carbon dioxide, extreme swings in climate and drastic effects on tropical vegetation, according to a study published in the journal Science Jan. 5.   view more (2007-01-05)

Rising carbon dioxide levels increase risks to satellites
Climate change is widely attributed to the build-up of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. However, scientists from the School of Engineering Sciences at the University of Southampton have shown that the impact of carbon dioxide is being felt in space too.   view more (2005-04-18)

HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at... view more (2001-06-21)

Norwegian Supernet Keeps the Pharaohs in Place
Several of the world's best known cultural treasures are located in areas prone to earthquakes. A new metal alloy will secure their existence.   view more (2004-11-01)

CONVERTING WASTE VEGETABLE OIL INTO A USEFUL ENERGY SOURCE
A RESEARCHER in environmental engineering at Staffordshire University has developed a technique to convert unwanted cooking oil into a ‘biodiesel’ which is a much cleaner alternative to fossil diesel. Dr Tarik Al-Shemmeri, a Reader in Environmental Engineering at Staffordshire... view more (2002-09-09)

Three ESA satellites reveal Etna's complexity
As detected by ESA satellite sensors, the recent eruptions of the Mount Etna volcano in Sicily are throwing huge amounts of ash and trace gases into the atmosphere. Working with data from the Global Ozone Monitoring Experiment (GOME) sensor onboard ESA's ERS-2 spacecraft, scientists at the German... view more (2002-10-30)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
Diatoms - some of which are so tiny that 30 can fit across the width of a human hair - are so numerous that they are among the key organisms taking the greenhouse gas carbon dioxide out of the Earth's atmosphere.   view more (2008-01-24)

Greenhouse theory smashed by biggest stone
A new theory to explain global warming was revealed at a meeting at the University of Leicester (UK) and is being considered for publication in the journal "Science First Hand".   view more (2006-03-14)

Increase in atmospheric moisture tied to human activities
Observations and climate model results confirm that human-induced warming of the planet is having a pronounced effect on the atmosphere's total moisture content.   view more (2007-09-18)

MIT: Nanoengineered concrete could cut CO2 emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen.   view more (2007-01-30)

A Fresh Spin in Quantum Physics: The 'Spin Triplet' Supercurrent
For the first time, scientists have created a "spin triplet" supercurrent through a ferromagnet over a long distance.   view more (2006-02-16)

Liquid CO2 drives rapid thrust of diamond-bearing structures
Freeze-dried ice cream looks like the original product, and even tastes pretty good, but "drying" ice cream at room temperature would leave a sour-smelling, sloppy mess.   view more (2007-05-03)

Researchers mimic lotus leaves for self-cleaning PV arrays, non-stick MEMS
Researchers at the Georgia Institute of Technology are mimicking one of Nature's best non-stick surfaces to help create more reliable electric transmission systems, photovoltaic arrays that retain their efficiency, MEMS structures unaffected by water and improved biocompatible surfaces able to... view more (2006-10-16)

Scripps research scientists identify blood component that turns bacteria virulent
Scientists from the Scripps Research Institute have discovered the key chemical that signals Bacillus anthracis, the bacterium that causes anthrax, to become lethal. This finding opens up new avenues of exploration for the development of treatments for bacterial infections.   view more (2008-11-24)

Findings advance use of adult stem cells for replacement bone
In a significant advance for regenerative medicine, researchers at Rice University have discovered a new way to culture adult stem cells from bone marrow such that the cells themselves produce a growth matrix that is rich in important biochemical growth factors.   view more (2006-02-14)

Nitrogen in the air feeds the oceans
A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow?   view more (2005-08-11)

Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates.   view more (2006-02-17)

Scientists at the University of Liverpool are embarking on a research cruise to help them understand recent major changes in the temperature of the Atlantic.   view more (2005-05-10)

Bones from calves good for fastening tooth implants
On Friday, November 8, Mats Hallman, Department of Odontology, Jaw Surgery, Ume'å University in Sweden, will defend a thesis that presents favorable results from implanting bone powder from calves to anchor tooth implants in humans. Tooth implants have long been a well-tested method to create... view more (2002-11-05)

Sea level on the rise - in real and virtual worlds
The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models.   view more (2007-02-05)

Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist.   view more (2008-01-14)
