Ocean warming detrimental to inshore fish species, Australian scientists report
ScienceDaily (May 20, 2011) — Australian scientists have reported the first known detrimental impact of southern hemisphere ocean warming on a fish species.The findings of a study published in Nature Climate Change indicate negative effects on the growth of a long-lived south-east Australian and New Zealand inshore species — the banded morwong.Scientific monitoring since 1944 … Continue reading
Scientists fly through the clouds to piece together climate puzzle
ScienceDaily (Mar. 16, 2011) — As scientists try to better understand and put together the puzzle of Earth’s climate, the role of clouds remains one of the most important missing pieces.Researchers from four NASA centers, other U.S. agencies and several colleges and universities are set to participate in the Mid-latitude Airborne Cirrus Properties Experiment (MACPEX), … Continue reading
Scientists discover agave’s tremendous potential as new bioenergy feedstock
ScienceDaily (Feb. 17, 2011) — An article in the current issue of Global Change Biology Bioenergy reviews the suitability of agave as a bioenergy feedstock that can sustain high productivity in spite of poor soil and stressful climatic conditions accompanying climate change.Agave, which grows successfully under hot, dry conditions, is currently used in the production … Continue reading
Scientists identify new implications for perennial bioenergy crops
ScienceDaily (Mar. 1, 2011) — A team of researchers from Arizona State University, Stanford University and Carnegie Institution for Science has found that converting large swaths of land to bioenergy crops could have a wide range of effects on regional climate.In an effort to help wean itself off fossil fuels, the U.S. has mandated significant … Continue reading
Scientists study magma as geothermal energy source
Magma could one day become a viable geothermal energy source, according to a team of scientists.Researchers from the University of California Davis had been drilling near an Icelandic volcano in 2009 and accidentally hit magma, creating a “high quality geothermal well”, explained Peter Schiffman, professor of geology at UC Davis and a member of the … Continue reading
Two severe Amazon droughts in five years alarms scientists
ScienceDaily (Feb. 3, 2011) — New research shows that the 2010 Amazon drought may have been even more devastating to the region’s rainforests than the unusual 2005 drought, which was previously billed as a one-in-100 year event.Analyses of rainfall across 5.3 million square kilometres of Amazonia during the 2010 dry season, recently published in Science, … Continue reading
Time machine for climate scientists: Earth’s extreme weather events since 1871 reanalyzed
ScienceDaily (Jan. 25, 2011) — From the hurricane that smashed into New York in 1938 to the impact of the Krakatoa eruption of 1883, the late 19th and 20th centuries are rich with examples of extreme weather. Now an international team of climatologists have created a comprehensive reanalysis of all global weather events from 1871 … Continue reading
Scientists Generate Two Energetic Electronic States from One Photon
The breakthrough could lead to a 35 percent increase in light-harvesting yield in cells for photovoltaics and solar fuels.The experiments, using a process called singlet fission, demonstrated a 200 percent quantum yield for the creation of two triplets of the molecule 1,3-diphenylisobenzofuran (DPIBF) at low temperatures.In singlet fission, a light-absorbing molecular chromophore shares its energy … Continue reading
