Low-cost reusable material could facilitate capture of carbon dioxide from power plants
Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide -... view more (2008-03-10)

Ocean acidification threatens cold-water coral ecosystems
Corals don't only occur in warm, sun-drenched, tropical seas; some species are found at depths of three miles or more in cold, dark waters throughout the world's oceans.   view more (2006-04-03)

Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers.   view more (2008-09-15)

Emission Reduction Assumptions for Carbon Dioxide Overly Optimistic, Study Says
Reducing global emissions of carbon dioxide (CO2) over the coming century will be more challenging than society has been led to believe, according to a research commentary appearing this week in the journal Nature.   view more (2008-04-03)

World's oldest rocks show how Earth may have dodged frozen fate of Mars
Carbon dioxide, a greenhouse gas that has become a bane of modern society, may have saved Earth from freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks.   view more (2007-02-06)

First ever 'wind scrubbers' to be built
The first phase of a working unit that can remove greenhouse gases from ordinary air is to be completed by the end of this year, according to a report in Chemistry & Industry magazine. Marina Murphy describes the groundbreaking work being done by brothers Allen and Burton Wright (and Burton's... view more (2004-04-02)

High-tech sieve sifts for hydrogen
Whether it's used in chemical laboratories or the fuel tanks of advanced automobiles, hydrogen is mostly produced from natural gas and other fossil fuels.   view more (2006-02-06)

Getting Warmer? Prehistoric Climate Can Help Forecast Future Changes
The first comprehensive reconstruction of an extreme warm period shows the sensitivity of the climate system to changes in carbon dioxide (CO2) levels as well as the strong influence of ocean temperatures, heat transport from equatorial regions, and greenhouse gases on Earth's temperature.    view more (2008-11-25)

Aerodynamic trailer cuts fuel and emissions by up to 15%
Creating an improved aerodynamic shape for truck trailers by mounting sideskirts can lead to a cut in fuel consumption and emissions of up to as much as 15%. Earlier promising predictions, based on mathematical models and wind tunnel tests by TU Delft, have been confirmed during road tests with an... view more (2008-04-18)

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)

Voyage to Southern Ocean aims to study air-sea fluxes of greenhouse gases
Scientists will embark this week from Punta Arenas, Chile, on the tip of South America, to spend 42 days amid the high winds and waves of the Southern Ocean. Here they hope to make groundbreaking measurements to explain how huge fluxes of climate-affecting gases move between atmosphere and sea, and... view more (2008-02-27)

World to be even hotter by century's end
If Earth's past cycles of warming and cooling are any indication, temperatures by the end of the century will be even hotter than current climate models predict, according to a report by University of California, Berkeley, researchers.   view more (2006-05-25)

Hypertension appears to be frequently undiagnosed in children and adolescents
In a study of children and adolescents with hypertension, only about one in four had been previously diagnosed with the condition, according to a study in the August 22/29 issue of JAMA.   view more (2007-08-22)

Doctors aggressively treat early heart attacks, research shows
An international study involving 467 hospitals in 12 countries found that doctors do a good job of aggressively treating the early stages of heart attacks - even before laboratory tests confirm the diagnosis.   view more (2007-04-10)

Research shows raised incidence of psychoses among migrant groups
Researchers examining the occurrence of psychoses among migrant groups have shown a raised incidence for all black and ethnic minority subgroups compared with white British counterparts, and reveal that the risk of psychoses for first and second generations varies by ethnicity.   view more (2008-11-05)

Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major... view more (2007-12-26)

Carbon sink capacity in northern forests reduced by global warming
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period (CUP) has on average decreased due to warmer autumn temperatures.   view more (2008-01-03)

Acne medication associated with abnormal blood test results
Elevated cholesterol levels and liver enzyme levels appear to be more common than previously thought among patients taking the acne medication isoretinoin, including those who had normal blood test results before beginning therapy.   view more (2006-08-22)

Geisinger study: PTSD a medical warning sign for long-term health problems
Geisinger research finds that veterans suffering from posttraumatic stress disorder (PTSD) are as likely to have long-term health problems as people with chronic disease risk factors such as an elevated white blood cell counts and biological signs and symptoms. However, few healthcare providers... view more (2008-02-14)

Climate swings have brought great CO2 pulses up from the deep sea
May 10, 2007, The Earth Institute at Columbia University—A study released today provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the... view more (2007-05-14)

Alarming growth in expected CO2 emissions in China, finds UC analysis
The growth in China's carbon dioxide (CO2) emissions is far outpacing previous estimates, making the goal of stabilizing atmospheric greenhouse gases even more difficult, according to a new analysis by economists at the University of California, Berkeley, and UC San Diego.   view more (2008-03-11)
