It can be concluded from the passage that, during the past two years, ----.

Few recent papers in biology have received as much
praise as Woo Suk Hwang's 2004 and 2005
announcements of cloning human embryonic stem
cells – or fallen as fast into disrepute with the
discovery that they were rank fakes. Embryonic stem
cell (ESC) research is no less promising today than it
was before Hwang's deceit was revealed; most
investigators continue to believe that it will eventually
yield revolutionary medical treatments. The fact that
no one has yet derived ESCs from cloned human
embryos simply means that the science is less
advanced than has been supposed over the past two
years. Still, Hwang has badly undermined the
reputation of a field that already has more than its
share of political and public relations problems. Some
longtime opponents of ESC research will
undoubtedly argue that Hwang's lies only prove that
the investigators cannot be trusted to conduct their
work ethically, and the public may believe them.
