Nobel Prize Goes to Stem Cell Trio

Medicine award recognizes US, British pioneers in gene targeting in mice

(Newser) - The Nobel Prize in medicine was awarded today to three stem-cell researchers who developed techniques for manipulating genes in mice. Mario R. Capecchi,  Martin J. Evans and Oliver Smithies  pioneered a process called gene targeting that allows specific genes to be turned on or off. This in turn allows... More »

Stem Cells Show Promise for Sick Lungs

Cells injected in mouse tails 'recolonize' lungs in breakthrough research

(Newser) - Scientists have successfully implanted stem cells into the lungs of mice in breakthrough research that could one day be used to develop new treatments for cancer patients or those suffering from major respiratory ailments. It's the first time stem cell research has focused on lungs because of the complex nature... More »

Brits Approve Experiments on Human-Animal Embryos

Hybrids to be created for stem cell research

(Newser) - Controversial experiments with embryos that are part human, part animal will be approved by a British commission tomorrow, the Guardian reports. Researchers hope to create the hybrid embryos to extract stem cells for use in potential treatments of Alzheimer's and Parkinson's diseases, and possibly motor neuron problems and spinal cord...

Human Stem Cells Grow Heart Muscle

Rats' cardiac tissue regenerated, halting progress of disease

(Newser) - Researchers are using human embryonic stem cells to regrow heart muscle and actually stop the progression of heart failure in rats. Although stems cells injected into rat heart tissue had previously been shown to become muscle tissue, very few had survived. Now  a team from the University of Washington has... More »

Common Virus Linked to Obesity

Fat cells exposed to virus grow in size and number

(Newser) - A virus that causes sore throats and eye infections may also contribute to obesity, new research suggests. leaving infected people with more and larger fat cells than uninfected people have. The discovery could lead to the development of anti-obesity vaccines and may help explain why some obese people have healthy... More »

Fake Cloner Stumbled Onto Major Stem Cell Find

Scandal overshadowed self-fertilizing eggs

(Newser) - The South Korean stem cell researcher who faked cloning a human egg and forged research results actually made a huge discovery without realizing it. Scientists reviewing his work have discovered that his team's embryonic stem cells were the product of unfertilized eggs that underwent parthenogenesis, or divided on their own,... More »

Fat Stem Cells Used to Grow Breasts

Breakthrough treatment could be ready next year

(Newser) - Bigger breasts—even new breasts—can be grown using a new treatment that extracts stem cells from fat in the stomach or buttocks, the BBC reports. The breakthrough could help women who have had mastectomies, or rival implants for those seeking bigger breasts. More »

Mouse Stem Cell Discovery Speeds Cures

'Missing link' embryonic cell boosts fight against Parkinsons, diabetes

(Newser) - British scientists have discovered a new type of stem cell in mice that's much closer to human embryonic stem cells, making them invaluable in the search for cures for diseases like Parkinson's and diabetes. Two independent teams from Oxford and Cambridge today revealed the "missing link" cells, which can... More »

Bush Kills Stem-Cell Bill

Wields veto for third time in presidency; Dems come out swinging

(Newser) - President Bush delivered the expected veto of a stem-cell research bill this afternoon, issuing instead an executive order to encourage the development of non-embryonic stem cells. "I will not allow our nation to cross this moral line," Bush said, setting off a predictable firestorm of protests from Dems.... More »

Bush Prepares to Re-Veto Stem Cell Bill

Without override votes, Dems force prez to renew unpopular rebuff

(Newser) - President Bush plans to sic the third veto of his presidency on a new bill that would soften restrictions on stem-cell research. Congressional Dems sent the bill to the president this week, and it looks eerily similar to one Bush sent back to fail a congressional override in January. More »

House OKs Stem Cell Bill; Veto Expected

(Newser) - The House approved the stem cell bill today by a wide but not veto-proof margin, sending the legislation to the White House to await rejection by President Bush. The bipartisan bill, which loosens restrictions on federal funding of embryonic stem cell research, passed the Senate in April and sailed through... More »

Stem Cell Breakthrough Spares Embryos

Technique sidesteps both ethical and technical difficulties

(Newser) - Normal skin cells can be transformed into the equivalent of stem cells in mice, researchers report, and the new technique may revolutionize research on humans. Because it doesn't involve embryos or eggs, the process skirts the ethical quagmires surrounding human stem cell research; the easy availability of raw material and... More »

Stem Cell Cure for Blindness in Sight

Fix for macular degeneration could be available in 5 years

(Newser) - A pioneering stem cell technique developed by British scientists and backed by an anonymous American benefactor could soon cure blindness in millions of people suffering from macular degeneration, the Daily Mail reports. The procedure involves injecting lab-grown embryonic stem cells into the back of an affected eye to repair the... More »

Britain OKs Human-Animal Hybrids for Research

(Newser) - The British government has reversed its stance on the creation of human-animal hybrid embryos and will propose allowing scientists to use them as sources of stem cells. Scientists developing treatments for incurable diseases would be allowed to grow the hybrid embryos for no longer than two weeks, and implanting them... More »

Bald Take Note: Mice Grow New Hair Follicles

(Newser) - In what could lead to a cure for baldness, scientists have discovered a technique for regrowing hair in an adult mammal for the first time. University of Pennsylvania researchers suceded in stimulating the growth of new skin complete with hair follicles in mice, the Sydney Morning Herald reports. More »

Bible Belt Brings Fight to Europe

Evangelicals attack stem cells, gays, truancy laws on the continent

(Newser) - American evangelicals have opened a new front in the culture wars—across the Atlantic.
