Because of the extremely cold nature of dry ice, Continental Carbonic provides safety tips when handling for the upcoming Halloween season. Decatur, IL (PRWEB) October 01, 2013 Dry ice can be used very effectively to create spooky effects at Halloween. It's called "dry ice" because it does not melt like wet ice. Instead, dry ice converts into carbon dioxide gas, which creates the “fog” effect ideal for Halloween. Dry ice is extremely cold (-109°F/-78.5°C)....

long term climate feedback loop
2013-08-06 10:24:29

Brett Smith for redOrbit.com - Your Universe Online According to University of Hawaii at Manoa oceanographer Richard Zeebe, future warming due to the current burning of fossil fuels will cause the Earth's global temperatures to rise longer than expected. In his report, which was published in Proceedings of the National Academy of Sciences, Zeebe looked at the long-term climate effects of today's human activity thousands of years into the Earth's future. "When we talk about climate...

Researchers find that a changing atmosphere affects how much water trees require Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water, a Harvard study has found. Studies have long predicted that plants would begin to use water more efficiently as atmospheric carbon dioxide levels rose. A research team led by Research Associate Trevor Keenan and Assistant Professor of Organismic and...

University of Adelaide researchers have developed a new nanomaterial that could help reduce carbon dioxide emissions from coal-fired power stations. The new nanomaterial, described in the Journal of the American Chemical Society, efficiently separates the greenhouse gas carbon dioxide from nitrogen, the other significant component of the waste gas released by coal-fired power stations. This would allow the carbon dioxide to be separated before being stored, rather than released to the...

Decision Making And Perception Of Risk Affected By Hunger
2013-06-25 12:39:40

Max-Planck-Gesellschaft Different neural circuits process environmental signals depending on the state of satiation Hungry people are often difficult to deal with. A good meal can affect more than our mood, it can also influence our willingness to take risks. This phenomenon is also apparent across a very diverse range of species in the animal kingdom. Experiments conducted on the fruit fly, Drosophila, by scientists at the Max Planck Institute of Neurobiology in Martinsried have shown...

SAE International Cooperative Research Project's expanded, extensive evaluation of HFO-1234yf refrigerant shows no change in its previous safety conclusions; Reiterates that concerns raised by one automaker based on "unrealistic" testing MORRIS TOWNSHIP, N.J., June 25, 2013 /PRNewswire/ -- Honeywell (NYSE: HON) announced today that SAE International, the world's leading automotive engineering association, has concluded that Honeywell's new low-global-warming-potential mobile air...

Elevated Carbon Dioxide Is making Arid Regions Greener
2013-05-31 11:25:37

American Geophysical Union Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth´s atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide “fertilization effect” has, indeed, caused a gradual greening from 1982 to 2010. Focusing on the southwestern corner of North America,...
