| Weather-making high-pressure systems predicted to intensify Posted: 05 Oct 2012 09:39 AM PDT High-pressure systems over oceans, which largely determine the tracks of tropical cyclones and hydrological extremes in much of the northern hemisphere, are likely to intensify this century, according to a new study. |
| Non-native plants show a greater response than native wildflowers to climate change Posted: 05 Oct 2012 07:09 AM PDT Warming temperatures in Ohio are a key driver behind changes in the state's landscape, and non-native plant species appear to be responding more strongly than native wildflowers to the changing climate, new research suggests. |
| Posted: 05 Oct 2012 07:09 AM PDT Coyotes are the largest of the mammalian carnivores to have made their way to, and thrived in, urban settings. A researcher estimates that about 2,000 coyotes live in the Chicago metro area. The coyote is "the test case for other animals," he says, such as wolves, bears and mountain lions. |
| Climate change: Aging of organic aerosols is caused by OH radicals Posted: 05 Oct 2012 05:25 AM PDT Atmospheric aerosol particles have a significant effect on climate. Researchers have now discovered that a chemical process in the atmosphere called aging determines to a major extent the concentration and the characteristics of aerosol particles. To date, this aspect has not been accounted for in regional and global climate models. |
| Climate sceptics more prominent in UK and US media Posted: 04 Oct 2012 05:09 PM PDT Climate sceptics are being given a more prominent, and sometimes uncontested, voice in UK and US newspapers in contrast to other countries around the world, new research suggests. |
| No evidence for 30-nm chromatin fibres in the mouse genome Posted: 04 Oct 2012 06:30 AM PDT Scientists have used three-dimensional imaging techniques to settle a long-standing debate about how DNA and structural proteins are packaged into chromatin fibers. The researchers revealed that the mouse genome consists of 10-nm chromatin fibers but did not find evidence for the wider 30-nm fibers that were previously thought to be important components of the DNA architecture. |
| Lessons from Iraq: Urban marshes and city survival Posted: 04 Oct 2012 06:29 AM PDT A scientist is continuing to build the case that natural wetlands, rather than irrigated fields, are the fertile ground from which cities initially emerged in Mesopotamia. And her conclusions about the importance of wetlands have particular resonance in southern Iraq. That area is both the site of her studies and the region where Saddam Hussein forcibly drained marshes to drive out the local populace after the first Gulf war. |
