NEW YORK (Reuters) – A long-awaited report on workplace wellness programs, which has still not been publicly released, delivers a blow to the increasingly popular efforts, Reuters has learned, casting doubt on a pillar of the Affordable Care Act and a favorite of the business community.

According to a report by researchers at the RAND Corp, programs that try to get employees to become healthier and reduce medical costs have only a modest effect. Those findings run contrary to claims by the mostly small firms that sell workplace wellness to companies ranging from corporate titans to mom-and-pop operations.

NEW YORK, May 23 (Reuters) – A headline-making paper last
week announcing that scientists had, for the first time, cloned
human embryos and harvested stem cells from them contains minor
errors, the authors acknowledged on Thursday. The mistakes
raised questions about how well the journal that published the
paper vetted it but probably do not undermine the study’s
central claim.

In a statement, the journal, Cell, said “there were some
minor errors” in the paper, but “we do not believe these errors
impact the scientific findings of the paper.”
