Professor Kang Sung-keun of Seoul National University told the Korea Times that tests show a stem cell line featured in their report in Science has genetic material from two parents. A university panel found that Stem Cell Line No. 1 was created from an unfertilized egg.
The panel found signs that the cells' genetic material did not match the original donor.
"The university may have made an error, as such phenomenon can happen in cancerous cells, which share a lot of characteristics with stem cells," Kang said. "That means that the cell line may indeed be a cloned but damaged one.".
Hwang has already enjoyed a measure of vindication. A report last week in Nature said that Snuppy, claimed by Hwang to be the first cloned dog, is the real McCoy.
Hwang's claim to have developed patient-specific stem cells has been determined to be fraudulent.

Mapping brain cancer to find best treatment
There's never a good time to have brain cancer. Still, Karl DuBose tries to look on the bright side. "It's weird to say, but today - and here in Seattle - might be the best time and place to get this disease," said the 45-year-old Everett, Wash., man, who was slammed with the diagnosis last summer.

Where does the gene activity of youth go? New findings may hold the key
New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age. A report in the November 26th issue of the journal
Cell, a Cell Press publication, reveals that a protein perhaps best known for its role in the life-extending benefits of a low-calorie diet also maintains the stability of the mammalian genome—the complete set of genetic instructions "written" in DNA.

Physicists Receive Patent for Improved Cancer Therapy Device
Four physicists at the U.S. Department of Energy's Brookhaven National Laboratory have been awarded U.S. Patent No. 7,432,516 B2 for the design of a “medical synchrotron” capable of delivering precision doses of proton radiation to cancerous tumors with minimal damage to surrounding healthy tissue. The new device would be more precise and less costly than existing proton-therapy systems, potentially increasing the availability and benefits of this treatment for cancer patients worldwide. The Brookhaven scientists are now seeking industrial partners to license and commercialize the technology.
