Researchers have long linkurl:debated;http://www.the-scientist.com/news/home/53256/ the presence of stem cells in the pancreas that generate insulin-producing beta cells. Now researchers have shown that beta cells are indeed produced in the adult mouse pancreas, which means the tissue must contain stem cells. The linkurl:paper,;http://www.cell.com/content/article/abstract?uid=PIIS0092867407016169, published today (January 24) in Cell, "reconciles some conflicting observations that have been aro

A nine-year-old girl enrolled in a stem cell therapy trial has died, according to the company running the trial, StemCells, Inc. An independent committee ruled that the death was not caused by the stem cell treatment. The girl was one of six children being treated for a neurodegenerative disorder -- called Batten Disease -- with transplants of linkurl:neural stem cells;http://www.the-scientist.com/blog/display/54169/ derived from fetal tissue.

I just got a call from John Collins, former chair of the biochemistry and molecular biology department at the University of New Hampshire, who told me that as of today he is officially reinstated as a professor. Collins had been banned from campus since last June after an incident involving another professor, and then dean of research, Stacia Sower, which you can read about linkurl:here;http://www.the-scientist.com/news/display/53383/ and linkurl:here.;http://www.the-scientist.com/news/display/

A linkurl:report;http://stemcells.alphamedpress.org/cgi/reprint/2007-0252v1.pdf published online today that researchers have cloned human embryos is not that much of an advance, according to one stem cell expert, Douglas Melton, at Harvard University. Researchers at Stemagen Corporation in La Jolla, Ca, reported that they cloned human embryos from adult oocytes using linkurl:somatic cell nuclear transfer,;http://www.the-scientist.com/article/display/53224/ according to a report published online

The new mandate that requires NIH-funded researchers to make their published papers publicly available threatens publisher and author interests, according to a linkurl:statement;http://www.pspcentral.org/publications/AAP_press_release_NIH_mandatory_policy.pdf released yesterday (January 3) by the Association of American Publishers (AAP). The mandate was signed into law by the president on December 26 as part of the 2008 appropriations bill, which went through many linkurl:iterations;http://www.

Modeling with model organisms Eye of Science / Photo Researchers, Inc Fruit fly genetics may help us understand how organisms can - or can't - adapt to climate change. By Andrea Gawrylewski Related Articles: 1 Hoffman's team reported that on the East Coast of Australia, the classical latitudinal genetic clines of Drosophila have shifted over the past 20 years an equivalent of 4 degrees latitude (some 400 km), which means that genetic clines are now found in f

The protein linkurl:Nanog,;http://www.the-scientist.com/article/display/53404/ long considered essential to maintaining pluripotency and promoting differentiation in embryonic stem cells, may play a lesser role in those processes, according to a study published this week in Nature. "The previous paradigm was that Nanog was infinitely coupled to differentiation," Ian Chambers of the University of Edinburgh, lead author of the study, told The Scientist. This new work has shown, Chambers continue
