Conflicting evidence about long-distance animal navigation.
Because of conflicting evidence about several fundamental issues, long-distance animal navigation has yet to be satisfactorily explained. Among the unsolved problems are the nature of genetic spatial control of migration and the relationships between celestial and magnetic compass mechanisms and between different map-related cues in orientation and homing, respectively. In addition, navigation ...
متن کاملCarcinogenicity of asbestos: convincing evidence, conflicting interests.
In spite of hard epidemiological and clinical evidence associating asbestos fibre with asbestosis and cancer, the issue is controversial and likely to remain so. The focus is now shifting to non-occupational exposure, differential risk to various asbestos fibre types and the relatively low level of carinogenicity of the chrysotile form. This creates further space for scientific debate and the o...
متن کاملZoopharmacognosy in Diseased Laboratory Mice: Conflicting Evidence
Zoopharmacognosy denotes a constellation of learned ingestive responses that promote healing and survival of infected or poisoned animals. A similar self-medication phenomenon was reported in diseased laboratory rodents. In particular, a series of studies revealed that autoimmune MRL/lpr mice readily consume solutions paired or laced with cyclophosphamide (CY), an immunosuppressive drug that pr...

متن کاملImprovement of DS Evidence Theory for Multi-Sensor Conflicting Information
A new DS (Dempster-Shafer) combination method is presented in this paper. As data detected by a single sensor are characterized by not only fuzziness, but also partial reliability, the development of multi-sensor information fusion becomes extremely indispensable. The DS evidence theory is an effective means of information fusion, which can not only deal with the uncertainty and inconsistency o...
