Separate teams of scientists ontwo continents revealed Tuesdaythat they have created stem cellsfrom human skin cells — a devel-opment that eventually could al-low researchers to sidestep thecontentious moral issues that havehobbled early studies in a promis-ing field.

The startling breakthrough washailed by parties on all sides of the

stem cell debate because it raisedthe prospect that the controversialdestruction of human embryosand the need to harvest eggs fromwomen donors might one day nolonger be needed.

“This has the potential to re-shape the politics and science of

stem cell research,’’ said Jesse Rey-nolds, a policy analyst for the Cen-ter for Genetics and Society, anOakland-based organization thatfavors stem cell studies.

The Rev. Thomas Berg, execu-tive director of the Westchester In-stitute, a Catholic ethics think tankin Thornwood, N.Y., said the newtechnique described in the two pa-pers is a major advance that passesethical muster. “This is almost amagical moment,’’ he said. “We

Nearly 100,000 pounds of liveDungeness crab apparentlycaught by Oregon fishermen nearthe Farallones are headed to BayArea seafood wholesalers for dis-tribution to consumers — a majorblow to local commercial fisher-men.

Hundreds of fishermen in SanFrancisco, Bodega Bay and HalfMoon Bay have been desperatelytrying to keep untested crab offdinner plates in the wake of theCosco Busan fuel spill in San Fran-cisco Bay. They have pledged notto harvest crab until the state con-firms the Dungeness are not con-taminated.

The state Office of Environ-

The Department of Fish andGame says that Dungeness caughtoutside a closed area of coastlinebetween San Mateo and Marincounties is safe to eat.
