"Had He created the Earth perfectly spherical, its axis might have been perpetually shifting by the influence of the other bodies of the system," Jefferson once told Thomson.
The wide geographical latitude (a typical axis might span Tarrytown and South Ossetia, or Manhattan and Tashkent) is in stark contrast to the narrowness of the characters' options, and the high price they pay for exercising any one of them.
Mars's surface is currently far too cold for life to exist, but in the past, the planet's axis might have periodically tipped over so that its north pole pointed at the sun during summer.
The change in rotational speed was probably too small to observe; however, the change in rotational axis might be detectable with observations made over an extended period of time.
Thus, the Nf1-Ras-Ets axis might be one of the select molecular pathways that are perturbed for initiation and maintenance in glioma.
In parallel with the existing human studies, we hypothesized that the HPA axis might be severely dysfunctional with subsequent severe electrolyte disturbances.
Climatologists John Kutzbach and Zhengyu Lui of the University of Wisconsin, Madison, however, thought the precession of Earth's axis might be the missing ingredient.
Despite studies suggesting that a dysfunctional HPA axis might be present before the clinical syndrome becomes apparent, the functioning of the HPA axis in high risk populations has not been well defined.
Our findings uncovered a novel signaling network initiated by SET that epigenetically modulated ESCC properties and suggest that targeting the regulatory axis might be a promising strategy to inhibit migration and metastasis.
The temple axis might also be designed to align with locations of religious significance, such as the site of a neighboring temple or the rising place of the sun or particular stars.
Tidal forces are thought to generate the heat that keeps Europa's ocean liquid, and a tilt in the spin axis might suggest that more heat is generated by tidal forces.
