A group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change in the biosphere, a planet-wide tipping point that would have destructive consequences absent adequate preparation and mitigation.
A detailed analysis of more than 4 million absorbent minerals has determined that new materials could help electricity producers slash as much as 30 percent of the “parasitic energy” costs associated with removing carbon dioxide from power plant emissions.
The research by scientists at Rice University, the University of California, Berkeley, Lawrence Berkeley National Laboratory (LBNL) and the Electric Power Research Institute (EPRI) was published online this week in the journal Nature Materials (“In silico screening of carbon-capture materials”).
Out of 150 entries an image of a nano-structure resembling a giraffe has won first prize in the 2012 Science as Art competition of the Materials Research Society. The creator of the picture is Shaahin Amini a Ph.D. student at … Continue reading
To produce the maximum amount of energy, solar cells are designed to absorb as much light from the Sun as possible. Now researchers from the University of California, Berkeley, have suggested – and demonstrated – a counterintuitive concept: solar cells should be designed to be more like LEDs, able to emit light as well as absorb it. The Berkeley team will present its findings at the Conference on Lasers and Electro Optics (CLEO: 2012), to be held May 6-11 in San Jose, Calif.
A team of scientists of Rutgers University, the University of California (LA & Davis) and the University of Alabama has today announced the discovery of a thus far undocumented species of frog. Although in face of the worldwide amphibian decline … Continue reading
When assessing the climate system it doesn’t hurt to include some geography to your statistical assumptions. After all, without mountains, oceans and coastlines there would be no weather, just one boring climatic average – and therefore no ground to create … Continue reading
We knew there must have been a connection between climate warming and damaging droughts in the world’s largest rainforest, as the two globally hottest years on record (2005 and 2010) coincide with the two record droughts in the Amazon – … Continue reading
Such an oil spill, which occurred during the 2007 Cosco Busan collision (container ship vs bridge) in San Francisco Bay, is (supposed to be) peanuts compared to for instance the 1989 Exxon Valdez’s 32,000,000 gallons of crude, or the BP … Continue reading
