Magnetoreception
Few subjects in animal behavior have more exotic mystery than magnetic-field sensitivity. A force we cannot sense, generated by events no one completely understands, creates field lines that pass through our bodies without any evident effect on us or on them. It is an energy felt as much by migrating lobsters on the sea floor as by ocean-crossing birds thousands of meters overhead, transduced i...
متن کاملStep-by-Step Acquisition of the Gibberellin-DELLA Growth-Regulatory Mechanism during Land-Plant Evolution
Angiosperms (flowering plants) evolved relatively recently and are substantially diverged from early land plants (bryophytes, lycophytes, and others [1]). The phytohormone gibberellin (GA) adaptively regulates angiosperm growth via the GA-DELLA signaling mechanism [2-7]. GA binds to GA receptors (GID1s), thus stimulating interactions between GID1s and the growth-repressing DELLAs [8-12]. Subseq...
متن کاملMagnetoreception in eusocial insects: an update.
Behavioural experiments for magnetoreception in eusocial insects in the last decade are reviewed. Ants and bees use the geomagnetic field to orient and navigate in areas around their nests and along migratory paths. Bees show sensitivity to small changes in magnetic fields in conditioning experiments and when exiting the hive. For the first time, the magnetic properties of the nanoparticles fou...
متن کاملA Proposal for an Electron-Transfer Mechanism of Avian Magnetoreception
In spite of many years of research, the mechanism of avian magnetoreception remains a mystery due to its seemingly insurmountable intricacies. Recently Xie and colleagues proposed that IscA1 can act as a protein biocompass due to the measured intrinsic ferromagneticity, and thus named it MagR. However, Meister’s calculations showed that the interaction energy of the magnetic moment of IscA1 wit...
متن کاملAn "unavoidable" death in a people's marathon.
With the increase in jogging and distance running as a means of attaining and maintaining fitness, and in the light of the difficulty in advising certain groups of patients about their capacity for such exercise, we report on several potentially avoidable factors in the death of a 45 year old Sheffield Marathon runner in June 1983.
