| A potential new target to fight drug-resistant pathogens identified Posted: 18 Dec 2012 05:23 AM PST Researchers from Max Planck Institute for Biophysical Chemistry in Göttingen are in search for new generation antibiotics to fight against multidrug-resistant bacteria. They have now identified a potential new target - a bacterial protein called elongation factor P (EF-P). They found that in the presence of EF-P, more than two consecutive residues of proline could be made. Drugs that block the production of proteins which causes virulence in these bacteria could aid in the quest for better antibiotics. |
| Plumes across the Pacific deliver thousands of microbial species to West Coast Posted: 17 Dec 2012 02:26 PM PST A surprising number of microorganisms – 99 percent more kinds than had been reported in findings published just four months ago – are leaping the biggest gap on the planet. Hitching rides in the upper troposphere, they’re making their way from Asia across the Pacific Ocean and landing in North America. |

What could be perceived as child’s play is the focus of serious theoretical research by Manoj Chaudhury and Partho Goohpattader, two physicists from Lehigh University, Bethlehem, Pensylvania, USA. Their study, which is about to be published in EPJ E, has one thing in common with childhood behaviour. It introduces a mischievous idea, namely studying the effect of random noise, such as vibrations, on the ball. They found it could lower the energy barrier to set the ball in motion. |
| Nanoparticles amplify tumor signals, making them much easier to detect in the urine Posted: 17 Dec 2012 12:45 PM PST Finding ways to diagnose cancer earlier could greatly improve the chances of survival for many patients. One way to do this is to look for specific proteins secreted by cancer cells, which circulate in the bloodstream. However, the quantity of these biomarkers is so low that detecting them has proven difficult. |
| New form of cell division found Posted: 17 Dec 2012 12:38 PM PST Researchers at the University of Wisconsin Carbone Cancer Center have discovered a new form of cell division in human cells. |
