A Possible Breakthrough in Reviving Extinct Species

My first choice is the dodo bird, although they did specifiy mammals here. Look through your freezers, please, for any freezer-burned meat you may have forgotten.
"Researchers at the Riken Center for Developmental Biology in Kobe, Japan, used cells from mice that had been frozen for 16 years at -20 Celsius (-4 degrees Fahrenheit).

They extracted the nucleus and injected it into eggs whose DNA had been removed. Several steps later, the scientists were able to clone the mice.

'This is the first time a mammal has been cloned from a sample stored at conditions reasonably close to what might be expected in permafrost,' Teruhiko Wakayama, who led the study, said in a statement.

'(It) gives some hope for those who might seek to clone extinct species from frozen carcasses.'" [CNN]

The advertisements are for Sw

Little Town Beseeches Obama’s Health Chief

This is from one of many town meetings across America about health care. It is the first one that former Senator, Tom Daschle , has attended. We have to keep the pressure on for a universal single-payer system. Nothing else makes practical sense. Mr. Daschle was joined at the meeting, which was held at the town’s firehouse, by several dozen other people. Among them were doctors and administrators from Reid Hospital in nearby Richmond, who told of patients who were flooding the emergency room there because they did not have primary care doctors or insurance coverage. “Our population hasn’t grown, yet our emergency department census has more than doubled,” Dr. Michael Baldwin, the department’s director, said of changes over the last 24 years. “Everyone used to have his own doctor. Now little more than half do.” Dr. Joseph Fouts, one of the area’s few general practitioners, said he dealt nearly every day with patients who had found jobs carrying health benefits but who were denied coverag
