Scientists in bone battle

A losing battle: weight regain does not restore weight loss-induced bone loss in postmenopausal women.

Previously, we reported significant bone mineral density (BMD) loss in postmenopausal women after modest weight loss. It remains unclear whether the magnitude of BMD change in response to weight loss is appropriate (i.e., proportional to weight loss) and whether BMD is recovered with weight regain. We now report changes in BMD after a 1-year follow-up. Subjects (n = 23) in this secondary analys...

By the scientists, for the scientists

My association with the JCB began very early in my scientific career. In fact, it predated my understanding that there would even be a scientific career. In the mid-1970s while still an undergraduate, the JCB published my very first paper, a contribution noted perhaps less so for its reporting the characterization of the first known protein in plant cell walls than for a footnote that called at...

Do Scientists Pay to Be Scientists?

This paper explores the relationship between wages and the scientific orientation of R&D organizations. Firms who adopt a science-oriented research approach (i.e., “Science”) allow their researchers to pursue and publish an individual research agenda.. The adoption of Science may be associated with a “taste” for Science on the part of researchers (a Preference effect) and/or as a “ticket of adm...

Humans as Scientists: Scientists as Humans

This article discusses how constructivist psychology might contribute to studies of the history and philosophy of science. It is suggested that this would be a fruitful topic for graduate research, and a brief analysis is provided of what would be required to model the construct systems involved in the Priestley-Lavoisier controversy over the roles of phlogiston and oxygen in calcification. It ...
