Scientific rigour: a heavy or light load to carry?

Spinal Anesthesia, Heavy Solution or Light?

LLY, writing in the Journal of the Michigan State Medical Society, says: " With the very great increase in the literature on spinal anaesthesia it seems regrettable that many articles appearing in the current literature are written either by the proponents or opponents of the method, and their analysis of the subject is reflected by opinions already formed as to its value or lack of valne." Any...

Semi-leptonic decays heavy-light to heavy-light

We present results for the QCD matrix elements involved in semi-leptonic decays of B-mesons into pseudo scalar heavy light states. The application of NRQCD heavy quarks allows for quark masses around the physical b-quark. We investigate the dependence of the form factors on the external momenta and looked at the mass dependence at zero recoil. For the first time, results for radially excited de...

Chromosome Segregation: Ndc80 Can Carry the Load

Dynamic attachments between kinetochores and spindle microtubules are required for chromosome bi-orientation in mitosis. A new study provides biophysical insight into how the Ndc80 complex may contribute to the formation of these attachments.

Planning and evaluating population interventions to reduce noncommunicable disease risk - reconciling complexity and scientific rigour?

Noncommunicable diseases (NCDs) are the leading global causes of morbidity and mortality. It is important to develop and deliver effective NCD prevention programs, but these have been difficult to evaluate. Technical approaches differ, with academic researchers, practitioners and policy makers each bringing different perspectives and priorities to the task of NCD program evaluation. Epidemiolog...
