Embryonic stem cell therapy got a step closer to the clinic Thursday after US researchers said they filed a request for government approval of human trials. http://www.physorg.com/news177865555.html Medicine & Health Thu, 19 Nov 2009 15:40:01 EST news177865555 (AP) -- Prosecutors demanded a four-year prison term Monday for a South Korean scientist disgraced in a cloning scandal that shook the international scientific community and led to his trial on fraud and other charges. http://www.physorg.com/news170317359.html Biology Mon, 24 Aug 2009 07:23:19 EST news170317359 The US government on Monday unveiled final rules for embryonic stem cell research, laying out ground rules for "ethically responsible, scientifically worthy" studies eligible for federal funds. http://www.physorg.com/news166163911.html Biology Tue, 07 Jul 2009 06:30:09 EST news166163911 A US-based fertility doctor claimed to have cloned 14 human embryos and transferred 11 of them into the wombs of four women in an interview published Wednesday. http://www.physorg.com/news159609841.html Biology Wed, 22 Apr 2009 09:04:39 EST news159609841 Faced with a new federal policy that opens the door for more embryonic stem cell research, conservatives have geared up for a political battle at the national and state level that goes to the core of their beliefs about the sanctity of human life. http://www.physorg.com/news156451856.html Biology Mon, 16 Mar 2009 19:51:40 EST news156451856 (AP) -- A showdown is shaping up in some of the nation's most conservative states over embryonic stem cell research, as opponents draw language and tactics from the battle over abortion to counter President Barack Obama's plan to ease research restrictions. http://www.physorg.com/news156013060.html Biology Wed, 11 Mar 2009 17:58:21 EST news156013060 US President Barack Obama will on Monday sign an executive order reversing Bush administration restrictions on federal funding for stem-cell research, a senior administration official said. http://www.physorg.com/news155587890.html Biology Fri, 06 Mar 2009 18:52:07 EST news155587890 A team of researchers from the University of the Basque Country (UPV-EHU) have developed a mathematical classification which makes it possible to select human embryos for use in assisted reproduction treatments. Scientists have used the morphology of embryos to select the best candidates for implantation in the woman's uterus. http://www.physorg.com/news154706235.html Biology Tue, 24 Feb 2009 13:58:16 EST news154706235 Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications. The shortage of human donor eggs has led to efforts to substitute animal oocytes. http://www.physorg.com/news152802480.html Biology Mon, 02 Feb 2009 13:08:34 EST news152802480 James Thomson knew that to send a cell back to its past was no trivial matter. Like generations of biologists, the University of Wisconsin-Madison stem cell pioneer had been taught that development was a one-way street; it began with an embryo and finished with all the mature cells that make up the body. Yet in the summer of 2007, Thomson and scientists around the globe were racing to do what once had been thought impossible: to reverse the natural process and return old cells to their embryonic origin. They sought the healing potential of embryonic stem cells - immortal in a lab dish, able to become any cell in the body - but without the controversial destruction of human embryos. http://www.physorg.com/news150098009.html Medicine & Health Fri, 02 Jan 2009 05:53:29 EST news150098009
