Research on Embryonic Stem Cells to Get OK, With Caveat

(Newser) - The Obama administration will issue new guidelines significantly expanding the scope of stem cell research in July, though some caveats leave scientists dubious, the New York Times reports. The new rules will likely allow federal funds to flow to researchers using surplus embryos created in fertility clinics, a practice the...

Vatican Condemns Obama Stem-Cell Decision

(Newser) - The Vatican is in a tizzy over President Obama’s decision to lift the federal ban on embryonic stem-cell research, the AP reports. A top official called it a “victory of politics over ethics” and said that “probably some drug companies, or some economic interests” influenced the move....

New Research Raises Hopes for Viable Human Cloning

Study finds cloned embryos share genetic traits with natural cells

(Newser) - Human cloning, for medicine or even reproduction, may be more realistic than ever, Wired reports. Researchers found genetic characteristics similar to normal human embryos in cloned human embryos. The findings are a first step toward therapeutic cloning, in which embryonic stem cells that can replace failing tissues are grown from...

Frozen Embryos Make Bigger Babies

Study finds no negative effects compared with fresh

(Newser) - When it comes to in vitro fertilization, frozen might be better than fresh, a new study shows. Infants born after being implanted in mothers' wombs as frozen embryos were no more likely than those from fresh stock to be born with congenital defects, the BBC reports; but they were also...

UK Approves Research on Human-Animal Embryos

Hybrids will be used for stem cell study

(Newser) - British legislators have voted to allow scientists to create hybrid human-animal embryos for stem cell research, the Daily Telegraph reports. The new laws will give British scientists more freedom to pursue hybrid research than those of any other country. The vote passed by a huge margin after supporters of the...

Human-Animal Embryos Created

Controversial cow-human creation lived for three days

(Newser) - In a brave new world breakthrough, British scientists for the first time have created animal-human hybrid embryos, the London Times reports. The nuclei of cow eggs were removed and replaced with ones from a human cell, creating "admixed" embryos—or "cybrids" whose genetic material is 99.9% human....
