Environment, Bioethics Under Vatican's Scrutiny

Church updates Catholic morality for modern, globalized life

(Newser) - Catholics must guard against "new sins" such as polluting the environment and using genetic modification, the Vatican says. Their church has updated the concept of sin for the contemporary world, paying special attention to the expanding and morally murky world of bioethics, a top official from the Apostolic Penitentiary,...

Angry Students Block Pope Visit

Profs say appearance would be affront to 'people of science'

(Newser) - Pope Benedict XVI has scrapped plans to speak at a prestigious Italian university after unprecedented protests by furious students and professors who accused him of justifying Galileo's trial and "affronting" people of science, the Los Angeles Times reports. The pope once described as "reasonable" the 400-year-old heresy trial...

Third Team Turns Skin Into Stem Cells

First time cells were taken from a volunteer, not lab grown

(Newser) - A third team of scientists has successfully turn skin cells into stem cells that can be coaxed into becoming any kind of tissue. The American researchers are the first group to manage the feat with a volunteer's cells, not cells grown in a lab, which demonstrates that such cells could...

Embryonic Stem-Cell Issue Still Dogs GOP

Pols can't nix research and back in-vitro clinics: Time writer

(Newser) - Last week's breakthrough in stem-cell research—the creation of cells from skin rather than embryos—is a tremendous scientific advance, writes Michael Kinsley in Time magazine. But the new science doesn't let hypocritical GOP politicians dodge the controversy over embryonic stem cells: They will still be risking human lives with...

New Stem Cells Cancer-Free

Kyoto scientists nix tumors in mice with new cell cocktail

(Newser) - Scientists who recently turned skin into embryonic stem cells are now tweaking the process to reduce cancer risk, Reuters reports. A team at Kyoto University grew live mice with a cell cocktail, but said the rodents grew tumors. So they nixed a gene called c-Myc1 and the next batch came...

Scientists Make Stem Cells Without Embryos

Long-awaited breakthrough bypasses ethical wrangling

(Newser) - Scientists have figured out how to make stem cells out of ordinary skin cells—a long-awaited breakthrough that could bypass ethical wrangling over embryos and eggs. Two teams of researchers, one American and one Japanese, arrived at the process independently, the Washington Post reports. One scientist called the discovery "...

Dolly Scientist Dumps Embryo Cloning Method

Switches to less controversial Japanese technique

(Newser) - The scientist who created the cloned sheep Dolly is now abandoning the technique he pioneered in favor of a rival method of cell modification developed in Japan. The Japanese approach, which genetically manipulates adult human cells, has proven less controversial than embryonic stem cell research. But scientist Ian Wilmut insists...

Scientists Clone Monkey Embryos

Stem cells successfully extracted, raising hopes for humans

(Newser) - Oregon scientists have successfully cloned dozens of monkey embryos and extracted stem cells from them, a long-sought breakthrough that raises hopes of doing the same in humans. After years of failure—and even fraud—scientists feared a fundamental barrier to primate cloning, the Independent reports. “To me, it’s...

Sprouting Eyes in Petri Dishes

Research that gave tadpoles a third eye could be boon for human sight

(Newser) - A lab fluke that resulted in tadpoles growing third eyeballs could be a major boon for human sight, leading to replacement optic parts or even whole eyes grown in petri dishes. A recent research project accidentally happened upon a trigger for eye formation in frogs—a nitrogen-bearing molecule—that may...

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...

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...

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...

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...

Ex-Surgeon General Alleges Censorship

Former top doc says administration plays politics with science

(Newser) - The Bush administration "did not want to hear the science" on subjects such as stem-cell research and abstinence-only sex ed, the ex-surgeon general says, and he was muzzled and marginalized when he tried "to be the doctor of the nation—not the doctor of a political party."...

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...

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....

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.

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...

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.
