US postdoc fabricates DNA data

By | May 9, 2008

A former postdoc at the University of Nebraska Medical Center (UNMC) falsified and fabricated DNA sequences and methylation status in unpublished data about a tumor suppressor gene, a UNMC investigation, in conjunction with the Office of Research Integrity (ORI), has found. From 2002-2005, Lois Bartsch worked in James Shull's laboratory at UNMC, researching the tumor suppressor gene, p16Cdkn2a, in rats. The investigation concluded that Bartsch altered the nucleotide sequence of the p16Cdkn2a pr

Autoimmune debate resolved?

By | May 8, 2008

New findings help resolve a long-standing debate in immunology over what type of cells are behind the progression of type-1 diabetes: attacker or protector cells. Scientists found that linkurl:autoimmune;http://www.the-scientist.com/supplement/2007-5-1/ destruction is likely due to a defect in levels of a cytokine within insulin-producing islets that reduce the numbers of protector cells. The research was published in today's online issue of linkurl:__Immunity.__;http://www.immunity.com/content

Microbes may have the capacity for a type of learning generally attributed to higher organisms, suggests a linkurl:paper;http://www.sciencemag.org/cgi/content/abstract/1154456 published online in Science today (May 8). "We have to start to think about bacterial behavior in a more sophisticated way," said linkurl:Saeed Tavazoie;http://genomics.princeton.edu/tavazoie/web/homes.html of Princeton University, who led the study. Researchers have long assumed that microbes respond to changes in the
