Breaking News: Growing Concerns Over STAP Cell Sources

March 27, 2014 | by Cynthia Fox | Comments

Cloning pioneer Teru Wakayama found two STAP stem cell batches made for recent Nature STAP papers were apparently not derived from a 129 mouse strain, as he was told, but F1 and B6 strains. While the erroneous data, which appeared in one of the papers, does not affect the works' main thrust, it is spurring calls for reviews of other STAP stem cell sources.

Nature Rejects Challenge to "Acid Stem Cells"; Scientists Try New Tips

March 24, 2014 9:51 am | by Cynthia Fox | Comments

Nature has rejected the paper of a top Hong Kong researcher whose lab several times failed to replicate results of the now-famous “acid bath” stem cell papers. That researcher is now trying to reproduce the work as it appears in yet another new updated protocol, posted Thursday by Harvard researchers. Meanwhile, in interviews, Harvard's Vacanti clarifies some mysteries.

"Acid Bath" Stem Cell Developments Rapidly Accumulate

March 17, 2014 10:16 am | by Cynthia Fox | Comments

Harvard's Charles Vacanti will post tips to make "acid bath" stem cells as early as today. This, even as "acid bath" lead author Haruko Obokata said she plans to withdraw her 2011 thesis. And four of 14 co-authors of "acid bath" papers—along with some coauthors’ boss— want them retracted. Yet that same boss signaled confidence in the papers' premise. “Almost too amazing,” says CIRM's recent chief.

New Stem Cell Sagas

February 25, 2014 11:20 am | by Cynthia Fox | Comments

A recipe detailing how to make extraordinary stem cells from ordinary cells—just by "stressing" them with acid—will "soon" be posted for all to try, says Riken. This could settle much controversy surrounding the cells...or spur more. Meanwhile, there have been "anecdotes" of success.

Stem Cells' Janus Faces

January 23, 2014 3:52 pm | by Cynthia Fox | Comments

Stem cells are the most potent cells in the body. But they can also become, it seems increasingly clear, the most dangerous cells in the body--serving as a biological safe house for HIV. Indeed, the ability of HIV to linger in the body for decades may be due to the simple fact that stem cells live for decades...Then, of course, there's cancer.

Dormant viruses can lie within a human host until the proper conditions for their activity are provided. You might think of viruses' as robots that need to take over a factory to make more of themselves. Without that, the viruses are dormant.

Nobel Aspirations

March 6, 2013 3:53 pm | by Cynthia Fox | Comments

Over the last few months, the Nobel Prize has generated much controversy—again. More than 3,000 scientists contributed to the most high profile science event of 2012: the discovery of the Higgs boson subatomic particle. Yet the Nobel can only be split between three laureates. Was the Nobel Prize finally obsolete, the press fretted, in one angst-ridden blog after another?
