| Scientists overcome major obstacle for stem cell therapies and research Posted: 08 Sep 2011 11:53 AM PDT Stem cells show great potential to enable treatments for conditions such as spinal injuries or Lou Gehrig's disease, and also as research tools. Scientists in the United States and Japan have developed a clever solution to the research obstacle of cell mixture purification that should prove more reliable than other methods, safer, and perhaps 100 times cheaper.  |
| Cellular communications visualized with a vibrant color palette Posted: 08 Sep 2011 11:51 AM PDT Scientists have dramatically expanded the palette of fluorescent highlighters that can be used to track the movement of messengers inside of single cells.  |
| The breathtaking dance of plants: How plants space out the pores through which they breathe Posted: 08 Sep 2011 11:50 AM PDT The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth, according to new research. The research could help scientists to tailor the number and arrangement of stomata to different environments. This could regulate the efficiency at which plants absorb carbon dioxide or diffuse water vapor.  |
| Posted: 08 Sep 2011 09:45 AM PDT In a significant advance for cosmetic and reconstructive medicine, scientists have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem cells.  |
| Genetic link to cattle diseases uncovered Posted: 08 Sep 2011 07:40 AM PDT The origin of three costly cattle diseases is genetically linked, according to new findings. Scientists have discovered a location on bovine chromosome 20 that is associated with the incidence of the most prevalent bacterial diseases -- pinkeye, foot rot and bovine respiratory disease (pneumonia) -- that affect feedlot cattle.  |
| Neutron scattering confirms DNA is as stretchy as nylon Posted: 08 Sep 2011 06:10 AM PDT Neutron scientists have measured how fast sound travels along DNA to determine its 'stiffness'. These findings help to explain how DNA folds, coils and denatures.  |
