More Trouble for the Schatten Lab, but One Potential Success

The U.S. Office of Research Integrity announced this week that it has found a former postdoc in Gerald Schatten's lab, Park Jong Hyuk, guilty of research misconduct for falsifying images in a manuscript on deriving embryonic stem cells from cloned...

My Second Scientific Paper: Matrix Protease Activity in Tumor Cell Invasion

The second paper from my undergraduate work at Texas A&M University was recently published in Molecular Cancer. The abstract can be found here, and the pdf of the full paper here. Molecular Cancer is an open access journal, so a...

More on Edible Cotton Seeds

Last month, I wrote a post about a research group at Texas A&M University that reported genetically engineering "edible cotton seeds" by using RNAi technology to stably and specifically knock out production of the gossypol toxin in the seeds of...

Congratulations to Daniel Rhoads

Via A Blog Around the Clock comes news that Daniel Rhoads, who writes the informative blog Migrations (and formerly A Concerned Scientist), has successfully defended his dissertation. So, after a few minor revisions, it looks like it won't be too...
