Dartmouth professor makes case for ethically universal stem cell lines
...rally deserving of protection, the challenge is to find methods of deriving hESCs that either leave the blastocyst intact and unharmed or avoid the use of normal blastocysts in the first place.

...he potential of egg preservation as well to really find out which is the best option: ovarian tissue or pure eggs. Also, a better way to preserve eggs which last about 24 hours outside the body without preservation would reduce the cost and logistical issues of coordinating donor eggs.

The cells that cover the lining of the lung are stimulated by the presence of talc to produce a factor that inhibits the growth of b...New bacterium discovered -- related to cause of trench fever

... mRNA stability level, Huang added. The idea is to find the mechanisms underlying the function of FMRP so in the future, we can develop more effective interventions. Huang said future studies will look more closely at how FMRP works with NXF2 to regulate its targets. She said, We expect to identify mor...Neuronal activity gives clues to working memory

We hope to find out if lignin content changes over time, with different growing conditions, or with different stock material, Smith said, so we can determine if there is an optimal time to harvest a particular crop.
