In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if a hand is rested on a table, the table's surface is immediately felt against the skin.
The American 1985 ASM-135 ASAT test was carried out, in which the Solwind P78-1 satellite flying at an altitude of 555 kilometres (345 mi) was struck by the 14-kilogram (31 lb) payload at a velocity of 24,000 kilometres per hour (15,000 mph; 6.7 km/s). When NASA learned of U.S. Air Force plans for the Solwind ASAT test, they modeled the effects ...

Kessler has received numerous awards for his pioneering work, the most recent being the 2010 Dirk Brower Award for his half-century career in astrodynamics.; The central main-belt asteroid 11267 Donaldkessler, discovered by American astronomer Schelte Bus at the Californian Palomar Observatory in 1981, was named in his honor on 13 April 2017 (M.P.C. 103977).
[5] French mathematician Alexandre Grothendieck wrote about The Sleepwalkers that "The metaphor of the 'sleepwalker' was inspired by the title of the wonderful book 'the sleepwalkers' by Koestler". [6] Irish writer John Banville stated that the "original idea" of his Revolutions Trilogy came from his reading of The Sleepwalkers, [7] and also ...
Depending on geographical and environmental pressures, high-altitude adaptation involves different genetic patterns, some of which have evolved not long ago. For example, Tibetan adaptations became prevalent in the past 3,000 years, an example of rapid recent human evolution. At the turn of the 21st century, it was reported that the genetic ...
