| In the eastern U.S., spring flowers keep pace with warming climate, blooming up to a month earlier Posted: 16 Jan 2013 04:53 PM PST Using the meticulous phenological records of two iconic American naturalists, Henry David Thoreau and Aldo Leopold, scientists have demonstrated that native plants in the eastern United States are flowering as much as a month earlier in response to a warming climate. |
| Malaria, typhoid -- not Ebola -- biggest health threat for travelers to tropics Posted: 16 Jan 2013 04:53 PM PST Feeling feverish after a visit to the tropics? It may not just be a bout with this year's flu. If you're a Western traveler, malaria and typhoid fever should top the list of diseases to discuss with your doctor when you return, especially following travel to Western Africa or India. |
| 'Shell-shocked' crabs can feel pain Posted: 16 Jan 2013 04:53 PM PST The food and aquaculture industries should reconsider how they treat live crustaceans such as crabs, prawns and lobsters. That's according to a researcher who has found that crabs are likely to feel pain. |
| Tree and human health may be linked Posted: 16 Jan 2013 01:38 PM PST Evidence is increasing from multiple scientific fields that exposure to the natural environment can improve human health. In a new study, the presence of trees was associated with human health. |
| New 'social' chromosome discovered in the red fire ant Posted: 16 Jan 2013 10:14 AM PST Researchers have discovered a social chromosome in the highly invasive fire ant that helps to explain why some colonies allow for more than one queen ant, and could offer new solutions for dealing with this pest. One of the researchers said, "Our discovery could help in developing novel pest control strategies. For example, a pesticide could artificially deactivate the genes in the social chromosome and induce social anarchy within the colony." |
| Posted: 16 Jan 2013 09:30 AM PST As rapid economic expansion continues to shape the Asian landscape on which many species depend, time is running out for conservationists aiming to save wildlife such as tigers and leopards. Scientists have used genetic analysis to find that the natural forest corridors in India are essential to ensuring a future for these species. According to two recent studies, these corridors are successfully connecting populations of tigers and leopards to ensure genetic diversity and gene flow. |
| New Antarctic geological timeline aids future sea-level predictions Posted: 16 Jan 2013 08:17 AM PST Radiocarbon dates of tiny fossilized marine animals found in Antarctica's seabed sediments offer new clues about the recent rapid ice loss from the West Antarctic Ice Sheet and help scientists make better predictions about future sea-level rise. This region of the icy continent is thought to be vulnerable to regional climate warming and changes in ocean circulation. |
| Iconic beach resorts may not survive sea level rises Posted: 16 Jan 2013 06:06 AM PST A leading coastal scientist has warned that some of the world's best known beach resorts may not survive projected sea level rises and that problems caused by changing sea levels are compounded by a lack of political will and short-term coastal management initiatives. |
| Ornamental fish industry faces increasing problems with antibiotic resistance Posted: 15 Jan 2013 11:38 AM PST The $15 billion ornamental fish industry faces a global problem with antibiotic resistance, a new study concludes, raising concern that treatments for fish diseases may not work when needed – and creating yet another mechanism for exposing humans to antibiotic-resistant bacteria. |
