| In cell culture, like real estate, the neighborhood matters Posted: 28 Aug 2011 02:12 PM PDT Ever since scientists first began growing human cells in lab dishes in 1952, they have focused on improving the chemical soup that feeds the cells and helps regulate their growth. But surfaces also matter, research shows.  |
| Controlling cells' environments: A step toward building much-needed tissues and organs Posted: 28 Aug 2011 02:12 PM PDT With stem cells so fickle and indecisive that they make Shakespeare's Hamlet pale by comparison, scientists have described an advance in encouraging stem cells to make decisions about their fate. The technology for doing so is an advance toward using stem cells in "regenerative medicine" -- to grow from scratch organs for transplants and tissues for treating diseases.  |
| Nano-thermometers show first temperature response differences within living cells Posted: 28 Aug 2011 02:12 PM PDT Using a modern version of open-wide-and-keep-this-under-your-tongue, scientists today reported taking the temperature of individual cells in the human body, and finding for the first time that temperatures inside do not adhere to the familiar 98.6 degree Fahrenheit norm.  |
| New roles emerge for non-coding RNAs in directing embryonic development Posted: 28 Aug 2011 11:10 AM PDT Scientists have discovered that a mysterious class of large RNAs plays a central role in embryonic development, contrary to the dogma that proteins alone are the master regulators of this process. The research reveals that these RNAs orchestrate the fate of embryonic stem cells by keeping them in their fledgling state or directing them along the path to cell specialization.  |
| Arabidopsis: Thanks to its flexible genome, the plant can adapt to various environmental conditions Posted: 28 Aug 2011 11:09 AM PDT The plant Arabidopsis thaliana is found throughout the entire northern hemisphere. But how does this small, inconspicuous plant deal with all these different extremes of environmental conditions? In order to discover the whole-genome sequence variation, the 1001 Genomes Project was launched in 2008. Researchers have now found that the Arabidopsis plant can adapt to various environmental conditions because of a very flexible genome.  |
