The amount of "hedging" language—words that suggest room for doubt—used by prominent newspapers in articles about climate change has increased over time, according to a new study by the University of Colorado Boulder.
The study, published in the journal Environmental Communication, also found that newspapers in the U.S. use more hedging language in climate stories than their counterparts in Spain.
PULLMAN, Wash.—Researchers at Washington State University have used a super-cold cloud of atoms that behaves like a single atom to see a phenomenon predicted 60 years ago and witnessed only once since.
The phenomenon takes place in the seemingly otherworldly realm of quantum physics and opens a new experimental path to potentially powerful quantum computing.
Tinkering with climate change through climate engineering isn't going to help us get around what we have to do says a new report authored by researchers at six universities, including Simon Fraser University.
After evaluating a range of possible climate-altering approaches to dissipating greenhouse gases and reducing warming, the interdisciplinary team concluded there's no way around it. We have to reduce the amount of carbon being released into the atmosphere.
WASHINGTON D.C. June 3, 2014 -- One of Leonardo da Vinci's masterpieces, drawn in red chalk on paper during the early 1500s and widely believed to be a self-portrait, is in extremely poor condition. Centuries of exposure to humid storage conditions or a closed environment has led to widespread and localized yellowing and browning of the paper, which is reducing the contrast between the colors of chalk and paper and substantially diminishing the visibility of the drawing.
"Water is everywhere, is biocompatible, cheap, and easy to apply," said Legrain. Using water instead of solder also speeds up the folding of each individual structure. If the water-based process is further developed to fold multiple structures at once, it could become cheaper than current self-folding approaches, said Legrain.
HOUSTON – (June 3, 2014) – Rice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads.
A porous material invented by the Rice lab of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and lets it go once the pressure is released. The material shows promise to replace more costly and energy-intensive processes.
Results from the research appear today in the journal Nature Communications.
WOODS HOLE, Mass.— As forests age, their ability to grow decreases, a new study by Marine Biological Laboratory (MBL) scientists and colleagues has determined. Since most U.S. forests are maturing from regeneration that began about 100 years ago when extensive clear-cutting occurred, the study suggests the future growth of U.S. forests will decline.
There are only around 500 North Atlantic right whales alive today. In an effort to further protect these critically endangered animals, a recent NOAA regulation required large vessels to reduce speed in areas seasonally occupied by the whales. The policy of notifying--but not necessarily citing--speeding vessels in protected areas was effective in lowering their speeds, helping to protect these magnificent creatures from ship collisions, while keeping punitive fines to mariners to a minimum.
PORTLAND, Ore. — A widely available dietary supplement that had been considered safe — and that some claim provides anti-aging and other health benefits — caused significant developmental abnormalities in the pancreas of offspring of pregnant monkeys who were given the supplement, according to a study published today in the FASEB Journal, from the Federation of American Societies of Experimental Biology.
Because of the results, authors of the study strongly recommend that pregnant women or women who might get pregnant avoid taking the supplement.
Some 56 million years ago, a massive pulse of carbon dioxide into the atmosphere sent global temperatures soaring. In the oceans, carbonate sediments dissolved, some organisms went extinct and others evolved.
A new Yale-led study challenges the long-held assumption that climate is the primary driver of how quickly organic matter decomposes in different regions, a key piece of information used in formulating climate models.
In a long-term analysis conducted across several sites in the eastern United States, a team of researchers found that local factors — from levels of fungal colonization to the specific physical locations of the wood — play a far greater role than climate in wood decomposition rates and the subsequent impacts on regional carbon cycling.
The paleoclimate record for the last ice age — a time 21,000 years ago called the "Last Glacial Maximum" (LGM) — tells of a cold Earth whose northern continents were covered by vast ice sheets. Chemical traces from plankton fossils in deep-sea sediments reveal rearranged ocean water masses, as well as extended sea ice coverage off Antarctica. Air bubbles in ice cores show that carbon dioxide in the atmosphere was far below levels seen before the Industrial Revolution.
Troy, N.Y. – Research published today in the Proceedings of the National Academy of Sciences makes it possible to predict how subjecting metals to severe pressure can lower their electrical resistance, a finding that could have applications in computer chips and other materials that could benefit from specific electrical resistance.
