| Termites create sustainable monoculture fungus farming Posted: 22 Nov 2009 02:00 PM PST Food production of modern human societies is mostly based on large-scale monoculture crops, but it now appears that advanced insect societies have the same practice. Our societies took just ten thousand years of (mainly cultural) evolution to adopt this habit and we are far from convinced that it is sustainable. Farming ants and termites had tens of millions of years to evolve their fungus farming systems and here monocultures are apparently evolutionary stable. |
| Sugar-coated polymer is new weapon against allergies and asthma Posted: 22 Nov 2009 02:00 PM PST Scientists have developed sugar-coated polymer strands that selectively kill off cells involved in triggering aggressive allergy and asthma attacks. Their advance is a significant step toward crafting pharmaceuticals to fight these often life-endangering conditions in a new way. |
| Toward home-brewed electricity with 'personalized solar energy' Posted: 22 Nov 2009 02:00 PM PST New scientific discoveries are moving society toward the era of "personalized solar energy," in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities. |
| Researchers find new piece of bovine spongiform encephalopathy (BSE) puzzle Posted: 22 Nov 2009 02:00 PM PST A new treatment route for bovine spongiform encephalopathy (BSE) and its human form Creutzfeldt Jakob disease could be a step closer based on new results from scientists in the UK. The team has found that a protein called Glypican-1 plays a key role in the development of BSE. |
| Sweet as can be: How E. coli gets ahead Posted: 22 Nov 2009 02:00 PM PST Scientists have discovered how certain bacteria such as Escherichia coli have evolved to capture rare sugars from their environment giving them an evolutionary advantage in naturally competitive environments like the human gut. |
| Shifting blame is socially contagious Posted: 22 Nov 2009 02:00 PM PST Merely observing someone publicly blame an individual in an organization for a problem -- even when the target is innocent -- greatly increases the odds that the practice of blaming others will spread with the tenacity of the H1N1 flu. |
| Solar winds triggered by magnetic fields Posted: 22 Nov 2009 08:00 AM PST Solar wind generated by the sun is probably driven by a process involving powerful magnetic fields, according to a new study led by researchers based on the latest observations from the Hinode satellite. |
| 'Slimming gene' discovered that regulates body fat Posted: 22 Nov 2009 08:00 AM PST Scientists have discovered a previously unknown fruit fly gene that controls the metabolism of fat. Larvae in which this gene is defective lose their entire fat reserves. Mammals carry a group of genes that are structurally very similar. The scientists therefore hope this research could lead to new medicines to fight obesity. |
| DNA molecules in moss open door to new biotechnology Posted: 22 Nov 2009 08:00 AM PST Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research. |
| Tooth-binding micelles containing antimicrobials may provide long-term cavity protection Posted: 22 Nov 2009 08:00 AM PST A new study suggests that tooth-binding micelles (or particles) may provide long-term cavity protection by adhering to tooth surfaces and gradually releasing encapsulated antimicrobials. Formulation of a mouthwash-based delivery system is anticipated, ultimately simplifying application and increasing at-home patient compliance. |
| Energy-saving powder may allow exploitation of unused reserves of natural gas Posted: 22 Nov 2009 08:00 AM PST Chemists are using a simple method to convert methane to methanol -- something that has the potential to exploit previously unused reserves of natural gas. |
| Health-care debate linked to risk of dying in US and Europe Posted: 22 Nov 2009 08:00 AM PST A new Web site allows users to explore differences in the probability of dying across European countries and the US states for men and women of different ages and races. |
| Mysteriously warm times in Antarctica Posted: 22 Nov 2009 02:00 AM PST A new study of Antarctica's past climate reveals that temperatures during the warm periods between ice ages (interglacials) may have been higher than previously thought. The latest analysis of ice core records suggests that Antarctic temperatures may have been up to 6°C warmer than the present day. |
| Bone implant offers hope for skull deformities Posted: 22 Nov 2009 02:00 AM PST A synthetic bone matrix offers hope for babies born with craniosynostosis, a condition that causes the plates in the skull to fuse too soon. |
| Clearer view of how eye lens proteins are sorted Posted: 22 Nov 2009 02:00 AM PST New research reveals how proteins that are critical for the transparency of the eye lens are properly sorted and localized in membrane bilayers. The study analyzes how interactions between lipid and protein molecules can selectively concentrate proteins in certain regions of the cell membrane. |
| Three IVF attempts double chances of live birth Posted: 22 Nov 2009 02:00 AM PST Just one in three women gives birth after a single IVF attempt, but the cumulative chance of a live birth increases with each cycle -- where women are offered three cycles nearly two thirds go on to have babies, reveals new research. |
| Emissions increase despite financial crisis Posted: 22 Nov 2009 02:00 AM PST Fossil carbon dioxide emissions increased by 40 percent from 1990 to 2008, according to new findings. Coal has bypassed oil as the largest source of CO2 emissions. |
| Bypassing the blues: Telephone treatment for depression post-bypass surgery improves quality of life Posted: 22 Nov 2009 02:00 AM PST Coronary artery bypass graft patients who were screened for depression after surgery and then cared for by a nurse-led team of health care specialists via telephone reported improved quality of life and physical function compared to those who received their doctors' usual care, according to a new study. |
